Detailed ways

The present application is described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, under the premise of no conflict, the embodiments or technical features described below can be arbitrarily combined to form new embodiments.

FIG1 is a schematic diagram of a first embodiment of a plastic frame of the present application. The present application discloses a plastic frame 110, which is used to support a display panel 300. The plastic frame 110 includes a first frame 111 and a second frame 120 connected end to end. The first frame 111 is used to connect to the side of the display panel 300, and the second frame 120 is used to connect to one side of the light incident surface of the display panel 300. A groove 140 is provided on one side of the first frame 111 and the second frame 120 close to the display panel 300, and the groove 140 is filled with a Filled with fixing glue 170; the first frame 111 and the display panel 300, as well as the second frame 120 and the display panel 300 are connected via the fixing glue 170; that is, the display panel 300 is connected to the glue frame 300 via the fixing glue 170, and a part of the fixing glue 170 will be filled in the groove 140 due to external force extrusion and other factors, and the other part of the fixing glue 170 remains on the upper surface of the first frame 111 and the second frame 120, and is tightly connected to the side of the display panel 300 and one side of the light incident surface.

In the present application, grooves 140 are provided on the first frame 111 and the second frame 120 that respectively connect the side and bottom of the glue frame 110 and the display panel 300. The surface area of the first frame 111 and the second frame 120 that connect the side and bottom of the display panel 300 is increased by the grooves 140. When the display panel 300 is installed on the glue frame 110, the first frame 111 limits the display panel 300, and the second frame 120 supports the display panel 300. The fixing glue 170 is filled between the first frame 111 and the second frame 120 and the display panel 300. The fixing glue 170 is filled into the grooves 140, thereby increasing the connection area between the fixing glue 170 and the glue frame 110, improving the stability of the connection between the display panel 300 and the glue frame 110, and effectively improving the problem that the glue frame 110 and the display panel 300 are easily detached due to the narrow adhesion width of the narrow-frame display device 10.

Furthermore, the plastic frame 110 is made of plastic or rubber material. When the gap distances between the first frame 111 and the second frame 120 and the display panel 300 are both D, the relationship is satisfied: 0.1 mm ≦ D ≦ 2 mm. The sealing gap between the display panel 300 and the plastic frame 110 can be freely adjusted between 0.1 mm and 2 mm to achieve a narrower frame or a better buffer protection effect.

Among them, the glue frame 110 is black or gray in color, and is made of plastic, synthetic rubber, etc.; the shape of the groove 140 can be a U-shaped or V-shaped groove 140, and the groove 140 serves to increase the contact surface area of the glue and reduce the risk of glue overflow; the fixing glue 170 can be black or gray hot melt glue, epoxy glue, etc.

In this embodiment, by using black sealing glue to bond the wrapping frame 110 and the side and bottom of the display panel 300, a relatively complete protection is formed for the entire side of the display panel 300, and due to the large sealing area, the overall fixing effect is better; it can replace the conventional double-sided tape fixing method and effectively reduce the risk of edge screen breakage and peeling of the narrow-frame display panel 300.

Specifically, as shown in Figure 1, there are multiple grooves 140, some of the grooves 140 are set on the first frame 111, and are arranged at intervals along the thickness direction of the display panel 300; some of the grooves 140 are set on the second frame 120, and are arranged at intervals along the length direction of the display panel 300, and the grooves 140 are arc-shaped or conical.

In the present application, a plurality of grooves 140 are arranged at intervals on the first frame 111 and the second frame 120. The surface area of the first panel and the second frame 120 connected to the side and bottom of the display panel 300 is increased by the structural design of the plurality of grooves 140. When the display panel 300 is installed on the glue frame 110, the first frame 111 limits the display panel 300, and the second frame 120 supports the display panel 300. The fixing glue 170 is filled between the first frame 111 and the second frame 120 and the display panel 300. The fixing glue 170 is filled into the plurality of grooves 140 of the first frame 111 and the second frame 120, thereby increasing the connection area between the fixing glue 170 and the glue frame 110. At the same time, in the present application, The groove 140 is arc-shaped or conical, which is beneficial to improving the connectivity between the fixing glue 170 and the glue frame 110. For example, when the groove 140 is arc-shaped, the entire groove 140 gradually narrows from the opening position to the bottom position of the groove. When the fixing glue 170 flows into the multiple grooves 140 of the first frame 111 and the second frame 120, the fixing glue 170 has a certain gripping force in the groove 140 and is not easy to detach from the groove 140, thereby improving the connection stability between the fixing glue 170 and the glue frame 110, and further improving the connection stability between the display panel 300 and the glue frame 110, effectively improving the problem of easy detachment of the glue frame 110 and the display panel 300 due to the narrow adhesion width of the narrow-frame display device 10.

In one embodiment, the cross section of the groove 140 is an arc shape, in which case the groove 140 may be a spherical groove; the groove 140 is dug out on the upper surface of the first frame 111 or the second frame 120, the groove 140 is spherical, and the top of the groove 140 is a small opening; the spherical groove 140 may be formed by digging, or by integral injection molding with the glue frame 110. When the spherical groove 140 is provided and the fixing glue 170 is applied, a part of the fixing glue 170 flows into the groove 140 and fills the groove 140; another part of the fixing glue 170 forms a thin colloid film on the upper surface of the first frame 111 or the second frame 120, and the colloid film and the fixing glue 170 in the groove 140 are connected through the opening at the top of the groove 140, and the two together connect the display panel 300 and the fixing glue 170 of the glue frame 110.

Since the groove 140 is spherical, the groove 140 tightly wraps the part of the fixing glue 170 located in the groove 140, and the fixing glue 170 is not easily pulled out from the first frame 111/the second frame 120, so that the fixing glue 170 and the first frame 111/the second frame 120 are tightly connected together, and the fixing glue 170 located on the upper surface of the first frame 111/the second frame 120 is relatively flat, and the colloid film of the fixing glue 170 is tightly connected to the display panel 300, which makes the display panel 300 and the glue frame 110 tightly connected together through the fixing glue 170, and the two are not easy to separate, thereby enhancing the installation stability of the display panel 300. Due to the tight connection between the display panel 300 and the glue frame 110, the two can be regarded as a whole, and when the ambient temperature changes, the two will not separate, and the two will move as a whole when deformed to adapt to the deformation caused by the change in ambient temperature, so as to avoid the display panel 300 being stretched or compressed alone to generate stress, resulting in damage to the display panel 300.

At the same time, since the first frame 111/the second frame 120 has a plurality of grooves 140, the fixing glue 170 filled in the grooves 140 forms a plurality of supporting points, and the plurality of supporting points also support the display panel 300. Moreover, the fixing glue 170 can expand and contract in the grooves 140, and when the ambient temperature changes, the fixing glue 170 in the grooves 140 deforms, thereby forming a plurality of floating supporting points for the display panel 300 through the fixing glue 170 in the grooves 140, further playing a role of buffering and protecting the display panel 300.

Figure 2 is a schematic diagram of a second embodiment of the rubber frame of the present application. As shown in Figure 2, the embodiment shown in Figure 2 is an improvement based on Figure 1. A plurality of grooves 140 are arranged on the first frame 111, and the extension direction of the groove bottom is inclined toward the direction where the second frame 120 is located. There is an inclination angle β between the groove 140 and the second frame 120; the inclination angle β between the groove 140 and the second frame 120 is an acute angle.

The present embodiment is different from the previous embodiment in that the present embodiment tilts the plurality of grooves 140 disposed on the first frame 111 toward the direction where the second frame 120 is located, so that the bottoms of the plurality of grooves 140 on the first frame 111 are more inclined to be perpendicular to the direction of the display panel 300. When the fixing glue 170 is applied between the display panel 300 and the glue frame 110, the fixing glue 170 will actively flow into the plurality of grooves 140 obliquely disposed on the first frame 111 due to the influence of gravity, and form a sinking trend until the entire groove 140 is completely filled, and the fixing glue 170 is fixed to the first frame 111. The glue 170 forms a "rivet"-like effect in the groove 140, so that the fixing glue 170 has a certain gripping force in the multiple grooves 140 of the first frame 111, and the fixing glue 170 is not easy to separate from the grooves 140 located on both sides of the glue frame 110, thereby improving the connection stability between the fixing glue 170 and the glue frame 110, and further improving the connection stability between the display panel 300 and the glue frame 110, effectively improving the problem of easy detachment of the glue frame 110 and the display panel 300 due to the narrow adhesion width of the narrow-frame display device 10.

Figure 3 is a schematic diagram of a third embodiment of the rubber frame of the present application. As shown in Figure 3, the embodiment shown in Figure 3 is an improvement based on Figure 1. The groove 140 includes a first groove 112 and a second groove 123. The first groove 112 is arranged on the first frame 111, and the second groove 123 is arranged on the second frame 120. The width of the first groove 112 is smaller than the length of the first frame 111 in the vertical direction, and is larger than half of the length of the first frame 111 in the vertical direction. The width of the second groove 123 is smaller than the length of the second frame 120 in the horizontal direction, and is larger than half of the length of the second frame 120 in the horizontal direction.

This embodiment is different from the previous embodiment in that, in this embodiment, only one groove 140 structure is provided on the first frame 111 and the second frame 120, namely, the first groove 112 and the second groove 123. The surface area of the first frame 111 and the second frame 120 connected to the side and bottom of the display panel 300 is increased by the first groove 112 and the second groove 123, and the width of the first groove 112 is smaller than the length of the first frame 111 in the vertical direction, and larger than half of the length of the first frame 111 in the vertical direction. The width of the second groove 123 is smaller than the length of the second frame 120 in the horizontal direction, and larger than half of the length of the second frame 120 in the horizontal direction. Such a design enables the first groove 112 and the second groove 123 to form a sufficiently large accommodating space on the first frame 111 and the second frame 120.

When the display panel 300 is installed on the glue frame 110, the first frame 111 limits the display panel 300, the second frame 120 supports the display panel 300, and the fixing glue 170 is filled between the first frame 111, the second frame 120 and the display panel 300. The fixing glue 170 will be filled into the first groove 112 and the second groove 123, thereby increasing the connection area between the fixing glue 170 and the glue frame 110, improving the stability of the connection between the display panel 300 and the glue frame 110, and effectively improving the problem of easy detachment of the glue frame 110 and the display panel 300 due to the narrow adhesion width of the narrow-frame display device 10.

Furthermore, after the fixing glue 170 is filled in the first groove 112 and the second groove 123 , it will be integrally embedded and fixed in the first groove 112 and the second groove 123 , further enhancing the connection stability between the fixing glue 170 and the display panel 300 and the glue frame 110 , making it difficult for the display panel 300 to peel off from the glue frame 110 .

Figure 4 is a schematic diagram of the structure of the first groove and the second groove in the fourth embodiment of the rubber frame of the present application. As shown in Figure 4, the embodiment shown in Figure 4 is an improvement based on Figure 3. The groove 140 includes a first groove 112 and a second groove 123. The first groove 112 is arranged on the first frame 111, and the second groove 123 is arranged on the second frame 120. The first groove 112 and the second groove 123 are both cross-shaped, and the bottom depth of the first groove 112 and the second groove 123 gradually increases from the end to the center.

The present embodiment improves the structure of the groove 140. In the present embodiment, only one groove 140 is provided in the first frame 111 and the second frame 123, namely, the first groove 112 and the second groove 123. By setting the first groove 112 and the second groove 123 to be cross-shaped, when the fixing glue 170 is applied between the glue frame 110 and the display panel 300, the fixing glue 170 will flow into the cross-shaped groove 140 of the first frame 111 and the second frame 120 respectively. After the fixing glue 170 completely fills the first groove 112 and the second groove 123, the fixing glue 170 also forms a cross shape in the first groove 112 and the second groove 123. The cross-shaped fixing glue 170 has good adsorption force and stability in the cross-shaped first groove 112 and the second groove 123. In addition, the multiple groove walls formed in different directions by the cross-shaped first groove 112 and the second groove 123 help to fix the fixing glue 170, thereby improving the fixing The stability of the connection between the glue 170 and the first groove 112 and the second groove 123 makes it difficult for the fixing glue 170 to fall off from the first groove 112 and the second groove 123; and, since the bottom depth of the cross-shaped first groove 112 and the second groove 123 gradually increases from the end to the center, when the fixing glue 170 flows into the first groove 112 and the second groove 123, it will form a similar "anchor" effect in the first groove 112 and the second groove 123, so that the fixing glue 170 has a certain gripping force in the first groove 112 and the second groove 123, and it is not easy to fall off from the first groove 112 and the second groove 123, thereby improving the connection stability between the fixing glue 170 and the glue frame 110, and further improving the connection stability between the display panel 300 and the glue frame 110, effectively improving the problem that the glue frame 110 and the display panel 300 are easily adhered and fall off due to the narrow adhesion width of the narrow-frame display device 10.

In addition, in order to further improve the stability of the connection between the plastic frame 110 and the display panel 300, the present application also improves the structure of the plastic frame 110, and the specific improvements are as follows:

Figure 5 is a schematic diagram of the fifth embodiment of the rubber frame of the present application. As shown in Figure 5, the embodiment shown in Figure 5 is an improvement based on Figure 1, and a covering member 113 is provided at one end of the first frame 111 close to the light emitting surface of the display panel 300, and the covering member 113 is buckled on the edge of the light emitting surface of the display panel 300.

In this embodiment, a covering member 113 is provided on a side of the first frame 111 close to the light emitting surface of the display panel 300. When the display panel 300 is installed on the glue frame 110, the first frame 111 and the second frame 120 of the glue frame 110 are first connected from the side and bottom of the display panel 300, and a fixing glue 170 is filled between the first frame 111 and the display panel 300 and between the second frame 120 and the display panel 300, so that the first frame 111 and the second frame 120 are respectively adhered from the side and bottom of the display panel 300. At the same time, the covering member 113 is buckled from the edge of the light emitting surface of the display panel 300. The combination of snap-fit fixing and adhesive fixing makes the connection between the display panel 300 and the glue frame 110 more stable. Even if the performance of the adhesive is reduced due to the increase in usage time or the influence of harsh environment, the display panel 300 will not fall off directly from the glue frame 110, thereby further improving the service life of the display module 100.

FIG6 is a schematic diagram of a first embodiment of the display module of the present application. As shown in FIG6 , the display module 100 further includes a support member 150 and a display panel 300. The support member 150 is disposed on a side of the second frame 120 away from the display panel 300. The support member 150 is connected to the second frame 120 to support the second frame 120 and form a receiving space with the second frame 120. The display panel 300 is installed in the plastic frame 110. When the display module 100 is an LCD (liquid crystal display) display module 100, the display module 100 further includes an optical module 160, which is installed in the receiving space.

The display module 100 in the present application may be a display module 100 of LCD, OLED, or Micro-LED. Since the rubber frame 110 in the present application is mainly made of plastic or rubber material, and the rubber frame 110 itself needs to bear the weight of the display panel 300 and may also be affected by external forces, during the long-term use of the display module 100, the rubber frame 110 is prone to deformation and may tear against the fixing glue 170, causing the fixing glue 170 to fall off the rubber frame 110.

In order to solve this problem, the present application additionally adds a support member 150 in the display module 100. The support member 150 in this embodiment can be made of metal material, specifically copper or iron. The second frame 120 is made of the support member 150, which can effectively prevent the rubber frame 110 from deforming and can provide relatively stable support for the display panel 300. In addition, since the support member 150 is set on the side of the second frame 120 away from the display panel 300 in the present application, and the support member 150 itself has a certain structural strength and is not easy to deform, the support member 150 can be used to carry the optical module 160, and the optical module 160 can be installed in the accommodating space formed between the support member 150 and the rubber frame 110. In this way, the original backplane structure can be eliminated, and the support member 150 can be used to replace the backplane, which is conducive to further reducing the overall size of the display module 100 and realizing the design of a narrow-frame and thin display device 10.

During the assembly process of the display panel 300 and the display module 100, the side and bottom sides of the display panel 300 in contact with the glue frame 110 are pre-coated with fixing glue 170, and then bonded to the glue frame 110. After being cured in a corresponding high temperature environment, they are assembled and fixed to the support member 150. Alternatively, the glue frame 110 and the support member 150 can be assembled and fixed first, and then the fixing glue 170 is applied to the corresponding position of the glue frame 110, and then fixed to the display panel 300, and the assembly is completed after being cured in a corresponding high temperature environment.

Since the support member 150 of the present application can replace the traditional back plate to support the optical film, and the material of the support member 150 can be metal or hard plastic, when the display device is in working state, the display panel 300 and the support member 150 will expand due to heat, and when the display device is not in working state, the display panel 300 and the support member 150 will shrink due to cold, and the expansion amount of the support member 150 is significantly greater than the expansion amount of the display panel 300. In order to improve the expansion and deformation of the support member 150 and the display panel 300 when heated or cooled, The support member 150 and the plastic frame 110 connected to the support member 150 are stretched or compressed on the display panel 300, and the display panel 300 is stretched or compressed on the plastic frame 110, causing damage to the display panel 300. Therefore, the present application also improves the support member 150, the plastic frame 110, and the connection between the support member 150 and the plastic frame 110, so as to ensure that the plastic frame 110 and the display panel 300 as a whole are protected when the support member 150 expands and contracts due to heat and cold; the following is a specific exemplary description:

FIG7 is a schematic diagram of a second embodiment of the display module of the present application. As shown in FIG7, the embodiment shown in FIG7 is an improvement based on FIG6. A protrusion 121 is provided on a side of the second frame 120 away from the display panel 300. The protrusion 121 includes a first connecting member 124 and a second connecting member 125. One end of the first connecting member 124 is connected to the second frame 120, and the other end is connected to one end of the second connecting member 125. The other end of the second connecting member 125 extends toward the direction of the first frame 111, and the first connecting member 124 is perpendicular to the second frame 120, and the second connecting member 125 is perpendicular to the second frame 120. There is a gap between the first connecting member 124, the second connecting member 125 and the second frame 120; the support member 150 includes a first supporting portion 151, a second supporting portion 152 and a third supporting portion 153, and the first supporting portion 151 and the second supporting portion 152 are respectively connected to the two ends of the third supporting portion 153 to form a U-shaped frame; the first supporting portion 151 and the second supporting portion 152 are respectively embedded in the gap between the second connecting member 125 and the second frame 120, and have a preset distance d between them and the first connecting member 124; the preset distance d is equal to the maximum expansion amount of the display panel 300.

This embodiment improves the structure of the support member 150 and the rubber frame 110. The rubber frame 110 is supported by the support member 150 with a U-shaped frame structure. When installing the support member 150 on the rubber frame 110, the first support part 151 and the second support part 152 of the support member 150 are first embedded and fixed in the gap between the second frame 120 and the second connecting member 125, so that the support member 150 can be stably fixed on the rubber frame 110, and the L-shaped protrusion 121 formed by the first connecting member 124 and the second connecting member 125 can better suspend and support the support member 150, so that the support member 150 is not easy to fall off from the rubber frame 110, which further improves the ability of the support member 150 to carry the optical module 160 and improves the structural stability of the display module 100.

Under the influence of the structural design of the glue frame 110 of the present application, the installation process of the display panel 300 of the present application is different from the traditional display panel installation process. After the traditional display panel and the glue frame are installed, there is a gap between the glue frame and the display panel, and the expansion of the display panel is released through the gap between the glue frame and the display panel, that is, the traditional display panel and the glue frame are actually in a partially separated state. After the display panel 300 of the present application is installed on the glue frame 110, glue is applied in the gap between the glue frame 110 and the display panel 300, and the glue flows into the groove 140 of the glue frame 110, thereby increasing the adhesive area of the glue, so that the glue frame 110 and the display panel 300 are better connected as a whole, and the display panel 300 is not easy to fall off from the glue frame 110, and the expansion of the display panel 300 directly acts on the glue frame 110, so that the glue frame 110 and the display panel 300 are deformed together.

In actual operation of the display module 100, as the display module 100 is used for an increased time, the display panel 300 expands due to heat, and the expansion of the display panel 300 causes the plastic frame 110 to deform. The protrusion 121 of the plastic frame 110 deforms toward the outside of the display panel 300 under the extrusion effect, and the distance between the first connecting member 124 of the protrusion 121 and the first supporting portion 151 and the second supporting portion 152 of the supporting member 150 in the gap gradually decreases. When the expansion of the display panel 300 reaches the maximum, the first connecting member 124 of the protrusion 121 just aligns with the first supporting portion 151 and the second supporting portion 152 of the supporting member 150. 52, the expansion of the display panel 300 is released by changing the spacing between the first support portion 151 and the second support portion 152 and the first connecting member 124 of the protruding portion 121 in the gap, thereby forming a buffer for the expansion of the display panel 300. That is, the present design can reduce the risk of the display panel 300 falling off the plastic frame 110, while transferring the squeezing of the plastic frame 110 by the original expansion of the display panel 300 to the change in displacement between the plastic frame 110 and the support member 150, thereby releasing the expansion of the display panel 300, and effectively reducing the risk of damage caused by squeezing between the display panel 300 and the plastic frame 110 after the display panel 300 expands due to heat.

FIG8 is a schematic diagram of a third embodiment of the display module of the present application. As shown in FIG8 , the embodiment shown in FIG8 is an improvement based on FIG6 . The rubber frame 110 is made of an elastic and deformation-resistant material. A protrusion 121 is provided on the side of the second frame 120 away from the display panel 300. The protrusion 121 includes a first connecting member 124 and a second connecting member 125. The first connecting member 124 is provided between the second frame 120 and the second connecting member 125. One end of the first connecting member 124 is connected to the second frame 120, and the other end is connected to the second connecting member 125. The second connecting member 125 is parallel to the second frame 120. The support member 150 includes a first supporting portion 151, a second supporting portion 152 and a third supporting portion 153. The first supporting portion 151 and the second supporting portion 152 are respectively connected to the two ends of the third supporting portion 153, and the first supporting portion 151 and the second supporting portion 152 are respectively connected to the second connecting member 125.

The traditional back panel is fixed to the plastic frame by screws and other structures. The back panel is complicated to install and has an integral hard contact with the plastic frame. The expansion of the back panel will directly pull the plastic frame, which can easily cause damage to the plastic frame and the display panel connected to the plastic frame.

This embodiment improves the structure of the support member 150 and the rubber frame 110. When installing the support member 150 on the rubber frame 110, the first support portion 151 and the second support portion 152 of the support member 150 are first connected to the second connecting member 125 of the rubber frame 110 respectively by adhesive or double-sided tape, so that the support member 150 can be stably fixed on the rubber frame 110, and the adhesive is used to form a buffer layer-like effect between the support member 150 and the rubber frame 110, which is conducive to releasing the expansion of the support member 150.

The plastic frame 110 in this embodiment is made of an elastic and deformation-resistant material, and its own deformation can better buffer the large expansion of the support member 150. In the actual operation of the display module 100, as the display module 100 is used for an increasing period of time, the support member 150 is heated and expanded, and the first support portion 151 and the second support portion 152 of the support member 150 will generate a pulling force on the plastic frame 110 toward the outside of the display panel 300 due to the expansion, and the pulling force generated by the expansion of the support member 150 will first be transmitted to the second connecting member 125 of the plastic frame 110, and the second connecting member 125 will form a After the first buffer release, the pulling force will be transmitted to the first connecting member 124. Since the first connecting member 124 and the second connecting member 125 are in different directions, the pulling force generated by the deformation of the support member 150 is released from different directions through the first connecting member 124 and the second connecting member 125, which effectively weakens the effect of the pulling force on the plastic frame 110, making it difficult for the expansion of the support member 150 to be transmitted to the display panel 300, and effectively protecting the risk of the support member 150 expanding and driving the plastic frame 110 to squeeze the display panel 300, thereby damaging the display panel 300.

That is, the present design can reduce the risk of the display panel 300 falling off the plastic frame 110, while transferring the squeezing of the plastic frame 100 caused by the expansion of the support member 150 and the display panel 100 to the internal deformation of the plastic frame 110, thereby releasing the expansion of the support member 150, and effectively reducing the risk of damage caused by squeezing between the display panel 300 and the plastic frame 150 after thermal expansion.

FIG9 is a schematic diagram of a fourth embodiment of the display module of the present application. As shown in FIG9 , the embodiment shown in FIG9 is an improvement based on FIG8 , and the first connecting member 124 is inclined toward the outside of the display panel 300 , and the inclination angle α between the first connecting member 124 and the second connecting member 125 is an obtuse angle.

When the support member 150 expands due to heat, the first support portion 151 and the second support portion 152 of the support member 150 will expand toward the outside of the display panel 300. At this time, the pulling force generated by the expansion of the support member 150 is first transmitted to the second connecting member 125, and then transmitted to the first connecting member 124 by the second connecting member 125. When the first connecting member 124 tilts toward the outside of the display panel, the pulling force transmitted to the first connecting member 124 will be transmitted along the expansion direction of the support member 150, which is beneficial for the first connecting member 124 to release the expansion of the support member 150. When the temperature of the support member 150 continues to rise, the support member 150 expands too much toward the outside of the display panel 300, and the rubber frame 110 can withstand greater deformation, which is not easily transmitted to the display panel 300, thereby avoiding the expansion of the support member 150 and causing the rubber frame 110 to damage the display panel 300.

When the support member 150 expands due to heat, the display panel 300 will also expand due to heat, and the direction of expansion of the display panel 300 is the same as the direction of expansion of the support member 150, both of which expand toward the outside of the display panel 300. Therefore, the first connecting member 124 inclined toward the outside of the display panel 300 conforms to the expansion direction of the display panel 300 and the support member 150, and can buffer and release the expansion of the display panel 300 and the support member 150 at the same time, further improving the expansion release ability of the rubber frame 110 for the display panel 300 and the support member 150, and effectively reducing the risk of damage to the display panel 300 due to compression between the display panel 300 and the support member 150 and the rubber frame 110 after the display panel 300 and the support member 150 expand due to heat.

FIG10 is a schematic diagram of a fifth embodiment of the display module of the present application. As shown in FIG10 , the embodiment shown in FIG10 is an improvement based on FIG6 . The plastic frame 110 further includes a third frame 130 . The third frame 130 is formed by extending the first frame 111 in a direction away from the light emitting surface of the display panel 300 . A protrusion 121 is provided on a side of the second frame 120 away from the display panel 300 . The protrusion 121 extends in a direction away from the second frame 120 . There is a gap between the third frame 130 and the protrusion 121 . The support member 150 includes a first support portion 151, a second support portion 152 and a third support portion 153, the first support portion 151 and the second support portion 152 are respectively connected to the two ends of the third support portion 153 to form a U-shaped frame; the first support portion 151 and the second support portion 152 are respectively embedded in the gap between the third frame 130 and the protrusion 121; a buckle portion 131 is provided at one end of the third frame 130 away from the first frame 111, and the buckle portion 131 is buckled on the side of the third support portion 153 away from the optical module 160.

The present embodiment improves the structure of the support member 150 and the plastic frame 110. The plastic frame 110 is supported by the support member 150 of the U-shaped frame structure. When the support member 150 is installed on the plastic frame 110, the first support portion 151 and the second support portion 152 of the support member 150 are first embedded and fixed in the gap between the third frame 130 and the protruding portion 121 of the second frame 120. Then, the third support portion 153 of the support member 150 is buckled and fixed by using the buckle portion 131 of the third frame 130, so that the support member 150 can be stably fixed. On the rubber frame 110, the buckle portion 131 of the third frame 130 can effectively support the support member 150, further improving the ability of the support member 150 to carry the optical module 160, and making the support member 150 less likely to deform, effectively improving the problem that after the support member 150 is deformed due to the weight of the optical module 160 itself, the rubber frame 110 is pulled, causing the rubber frame 110 and the fixing glue 170 to tear and fall off; and the support member 150 is not easy to fall off from the rubber frame 110, further improving the structural stability of the display module 100.

Figure 11 is a schematic diagram of the sixth embodiment of the display module of the present application. As shown in Figure 11, the embodiment shown in Figure 11 is an improvement based on Figure 10, and the second frame 120 is respectively provided with through grooves 122 at positions corresponding to the first support portion 151 and the second support portion 152, and the width of the through grooves 122 is smaller than the width of the first support portion 151 and the second support portion 152 in the vertical direction.

This embodiment is different from the previous embodiment in that, in this embodiment, a through groove 122 is provided at a position of the second frame 120 corresponding to the first support portion 151 and the second support portion 152, and the structure of the through groove 122 will further increase the surface area of the second frame 120; and the width of the through groove 122 is smaller than the width of the first support portion 151 and the second support portion 152 in the vertical direction, so that the first support portion 151 and the second support portion 152 of the support member 150 will not pass through the through groove 122 and be inserted into the through groove 122, so as to prevent the first support portion 151 and the second support portion 152 from being inserted into the through groove 122 and contacting the display panel 300.

When the display panel 300 is installed on the glue frame 110, the fixing glue 170 is filled in the gap between the display panel 300 and the first frame 111 and the second frame 120. The fixing glue 170 will flow into the through groove 122 of the second frame 120 and completely fill the through groove 122 of the second frame 120. In this way, the area for the fixing glue 170 to adhere to the second frame 120 is further increased, thereby improving the stability of the connection between the display panel 300 and the glue frame 110, and effectively improving the problem of the glue frame 110 and the display panel 300 being easily detached due to the narrow adhesion width of the narrow-frame display device 10.

In addition, due to the provision of the through groove 122 on the second frame 120, after the fixing glue 170 is filled between the second frame 120 and the display panel 300, a "T-shaped" structural shape is formed between the display panel 300 and the second frame 120, that is, the fixing glue 170 is fixed in the through groove 122 of the second frame 120 in a manner similar to a rivet, and because the fixing glue 170 itself has a certain degree of viscosity, the fixing glue 170 in this embodiment has both adhesive and embedded fixing effects, further enhancing the connection stability between the fixing glue 170 and the display panel 300 and the glue frame 110, so that the display panel 300 is not easily peeled off from the glue frame 110.

Figure 12 is a schematic diagram of the seventh embodiment of the display module of the present application. As shown in Figure 12, the embodiment shown in Figure 12 is an improvement based on Figure 11, and the first support portion 151 and the second support portion 152 are respectively provided with a receiving groove 154 corresponding to the position of the through groove 122, and the recessed direction of the receiving groove 154 is the same as the extension direction of the through groove 122.

The present embodiment is different from the previous embodiment in that, in the present embodiment, a receiving groove 154 is further provided at the positions of the first supporting portion 151 and the second supporting portion 152 corresponding to the through groove 122 respectively; when the fixing glue 170 is filled between the first frame 111, the second frame 120 and the display panel 300, the fixing glue 170 will first flow into the through groove 122 of the second frame 120, and then flow into the receiving groove 154 of the first supporting portion 151 and the second supporting portion 152 through the through groove 122 of the second frame 120. At this time, the fixing glue 170 will fix the second frame 120 and the display panel 300. The first support portion 151 and the second support portion 152 of the support member 150 are bonded at the same time, which not only allows the fixing glue 170 to be bonded to the second frame 120, but also allows the fixing glue 170 to be bonded to the support member 150, further increasing the bonding area of the fixing glue 170, so that the bonding stability between the fixing glue 170 and the glue frame 110 is further improved, and by bonding the fixing glue 170 to the support member 150, the fixation between the support member 150 and the glue frame 110 is more stable, effectively preventing the support member 150 from falling off the glue frame 110.

It should be noted that, in the present embodiment, the covering 113 can be formed by directly folding one end of the first frame 111 close to the light-emitting surface of the display panel 300, that is, the covering 113 and the first frame 111 are integrally formed; or the covering 113 and one end of the first frame 111 are rotatably connected. When the display panel 300 needs to be installed on the rubber frame 110, the covering 113 can be rotated to a position flush with the first frame 111, and the display panel 300 is installed on the rubber frame 110 from top to bottom, and then the covering 113 is rotated to a position flush with the light-emitting surface of the display panel 300 to form a snap-on fixation for the display panel 300. Such a design can simplify the installation steps of the display panel 300 and the rubber frame 110, and effectively prevent the display panel 300 from falling off the rubber frame 110; in the present embodiment, only the covering 113 and the first frame 111 are integrally formed as an example.

The display module 100 of the present application may be a backlight module or an OLED display module 100 , etc., and the present application does not impose any specific limitation thereto.

FIG13 is a schematic diagram of an embodiment of a display device of the present application. As shown in FIG13 , the present application further discloses a display device 10, including a rear shell 200. The display device 10 also includes the above-mentioned display module 100, and the rear shell 200 wraps the display module 100. The rear shell 200 is generally made of metal or plastic. Since the display module 100 includes easily damaged optical films, optical devices, etc., the display module 100 is wrapped by the rear shell 200 to protect the display module 100, so as to prevent the display module 100 from colliding with the outside world and causing damage.

The display device 10 in the present application can be a narrow-framed electronic device with a display function, such as a mobile phone, a computer, a TV series, or a tablet computer. The present application does not limit the specific type of the display device 10.

In the narrow-frame display device 10, since the width of the portion where the display panel 300 and the display module 100 can actually be connected by adhesive is relatively narrow, the adhesive connection between the display panel 300 and the display module 100 in the display device 10 is prone to peeling off during use or transportation, or as the usage time increases and under the influence of environmental factors.

In view of the above problems, the present application improves the glue frame 110 in the display device 10 that is actually connected to the display panel 300 by gluing. The specific improvements are as follows:

In the present application, grooves 140 are provided on the first frame 111 and the second frame 120 that respectively connect the side and bottom of the glue frame 110 and the display panel 300. The surface area of the first frame 111 and the second frame 120 that connect the side and bottom of the display panel 300 is increased by the grooves 140. When the display panel 300 is installed on the glue frame 110, the first frame 111 limits the display panel 300, and the second frame 120 supports the display panel 300. The fixing glue 170 is filled between the first frame 111 and the second frame 120 and the display panel 300. The fixing glue 170 is filled into the grooves 140, thereby increasing the connection area between the fixing glue 170 and the glue frame 110, improving the stability of the connection between the display panel 300 and the glue frame 110, effectively improving the problem that the glue frame 110 and the display panel 300 are easily detached due to the narrow adhesion width of the narrow-frame display device 10, and further improving the quality and service life of the display device 10.

It should be noted that the inventive concept of the present application can form a large number of embodiments, but the application document is limited in length and cannot be listed one by one. Therefore, under the premise of no conflict, the embodiments or technical features described above can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effects will be enhanced.

The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
