Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be fully described by the detailed description with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, not all embodiments, and all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without inventive efforts fall within the scope of the present invention.
Fig. 1a is a schematic top view of a touch display panel according to an embodiment of the present invention. As shown in fig. 1a, the touch display panel 100 includes a display region 110 and a non-display region 120 disposed around the display region 110, and further, the touch display panel 100 includes a first substrate 111, a second substrate 112 disposed opposite to the first substrate 111, a touch electrode (not shown), a frame-shaped sealing structure 121, a pad contact 122, and a retaining wall 123, wherein the retaining wall 123 is disposed outside the frame-shaped sealing structure 121.
FIG. 1b is a schematic cross-sectional view taken along the dashed line AB in FIG. 1 a. As shown in fig. 1b, the touch electrode 113 and the pad 122 are located on a side of the second substrate 112 away from the first substrate 111, and the touch electrode 113 is electrically connected to the pad 122. The frame-shaped sealing structure 121 and the retaining wall are disposed between the first substrate 111 and the second substrate 112.
For example, in the embodiment of the present invention, the first substrate 111 may be an array substrate, and the second substrate 112 may be a color filter substrate.
According to the technical scheme provided by the embodiment, the retaining wall 123 is arranged between the first substrate 111 and the second substrate 112 in the non-display area 120 of the touch display panel 100, and the retaining wall 123 is located at the outer side of the frame-shaped sealing structure 121, so that glass fragments generated during cutting of the touch display panel 100 are prevented from entering a gap between the first substrate 111 and the second substrate 112 in the non-display area 120 where the pad contact 122 is located, pressure applied in the binding process of the touch flexible printed circuit board cannot indirectly act on the glass fragments, the problem that the metal wiring 115 on the first substrate 111 is broken due to the fact that the glass fragments are pressed downwards under force is avoided, and the production yield of products and the stability of the touch display panel are improved.
For example, the touch display panel 100 in this embodiment may be a special-shaped touch display panel. Specifically, the special-shaped touch display panel is a touch display panel with a finger shape not rectangular. When the touch display panel 100 is cut, the cutting path angle of the special-shaped touch display panel is relatively changeable, and compared with the rectangular touch display panel 100, more glass fragments are generated, so that more glass fragments enter a gap between the first substrate 111 and the second substrate 112 in the non-display area 120 where the pad contact 122 is located, and the risk of breakage of the metal wiring 115 on the first substrate 111 in the binding process of the touch flexible printed circuit board is increased. Therefore, the method of using the retaining wall 123 to prevent the glass debris from entering between the first substrate 111 and the second substrate 112 has a more obvious effect in the profiled touch display panel 100, and improves the production yield of the product and the stability of the touch display panel.
Alternatively, the pad contact 122 includes a plurality of pad leads 1221 arranged in sequence, and the dam 123 extends along the arrangement direction X of the pad leads 1221.
Illustratively, the length of the pad lead 1221 along the width direction Y of the dam 123 ranges from 600 μm to 900 μm.
It should be noted that the retaining wall 123 extends along the arrangement direction X of the pad pins 1221, so that the retaining wall 123 can be disposed around the region where the pad contact 122 is located, and further the retaining wall 123 can prevent glass debris from entering the gap between the first substrate 111 and the second substrate 112 in the non-display region 120 where the pad contact 122 is located, thereby avoiding the problem that the metal trace 115 is broken due to the glass debris being pressed down by force during the binding process of the touch printed circuit board.
As shown in fig. 1a, the retaining wall 123 includes a first retaining wall 1232 corresponding to the pad contact 122, and second retaining walls 1231 located at two sides of the first retaining wall 1232 in the arrangement direction X of the pad pins, and the length of the first retaining wall 1232 is greater than or equal to the total length of the plurality of pad pins 1221 along the arrangement direction X of the plurality of pad pins 1221.
For example, the width of the first retaining wall 1232 is smaller than the width of the second retaining wall 1231, the width of the first retaining wall 1232 ranges from 50 μm to 200 μm, and the width of the second retaining wall 1231 ranges from 600 μm to 800 μm. Here, the width of the first retaining wall 1232 and the width of the second retaining wall 1231 refer to the length of the first retaining wall 1232 and the second retaining wall 1231 in the direction perpendicular to the extending direction of the retaining wall 123, and since the second retaining wall 1231 is located at both sides of the first retaining wall 1232 in the arrangement direction X of the pad pins 1221, when the width of the second retaining wall 1231 is greater than the width of the first retaining wall 1232, the second retaining wall 1231 can cover both sides of the first retaining wall 1232, thereby preventing the glass chips generated in the cutting process from entering the inside of the touch display panel 100 from both sides of the first retaining wall 1232.
It should be noted that the total length of the plurality of pad leads 1221 is the sum of the width of the plurality of pad leads 1221 in the X direction and the length of a plurality of gaps, where a gap refers to a gap between two adjacent pad leads 1221. Because the width of second retaining wall portion 1231 is greater than the width of first retaining wall portion 1232, consequently, the length that sets up first retaining wall portion 1232 is greater than the total length of a plurality of pad pins 1221, can avoid second retaining wall portion 1231 to shelter from the light-permeable zone that part pad pin 1221 corresponds, make light can direct irradiation to the welding agent that every pad pin corresponds in the X direction, the solidification of welding agent is accelerated, realize pad pin 1221 and touch-control flexible printed circuit board's effective electricity and be connected.
Alternatively, as shown in fig. 1a and 1b, since the first retaining wall 1232 does not overlap with the pad lead 1221 along the width direction Y of the retaining wall 123, and the length of the first retaining wall 1232 is greater than or equal to the total length of the pad leads 1221 along the arrangement direction X of the pad leads 1221, the retaining wall 123 does not overlap with the pad contact 122 along the stacking direction Z of the first substrate 111 and the second substrate 112. By the arrangement, a sufficient light-transmitting area can be reserved for the pad contact 122, and the solder between each pad pin 1221 and the touch printed circuit board can be effectively cured by being irradiated by light.
As shown in fig. 1a and 1b, the touch display panel 100 and the frame-shaped sealing structure 121 may be octagonal, and the display area 110 may be circular. Illustratively, the black matrix layer 114 is used to block the portion outside the circular display area 110 so that light does not pass through the blocked area, thereby defining the display area 110 as a circle.
In fig. 1b, the touch electrode 113 extends to the outside of the frame-shaped sealing structure 121 to form a pad 122, i.e., the touch electrode 113 and the pad 122 may belong to the same complete film layer. In this embodiment, the forming manner of the pad contact 122 is not limited, and the pad contact 122 may be an independent structure in contact connection with the touch electrode 113, and may be disposed on a side of the touch electrode 113 away from the second substrate 112, or may be disposed on the same layer as the touch electrode 113.
It should be noted that, because the actually produced touch display panel 100 has a certain error with respect to the standard size, in order to avoid overlapping of adjacent structures, a certain gap is reserved between the adjacent structures when the standard size is designed.
For example, as shown in fig. 1b, the distance a between the first wall 1232 and the pad contact 122 along the wall width direction Y may be in a range of 0 to 100 μm.
Optionally, the distance b between the first retaining wall 1232 and the edge of the second substrate 112 may be in a range of 0 to 300 μm.
FIG. 1c is a schematic cross-sectional view along the dashed line CD in FIG. 1 a. As shown in fig. 1c, the distance c between the second barrier portion 1231 and the frame-shaped sealing structure 121 may be in the range of 0 to 250 μm.
It should be noted that the retaining walls 123 shown in fig. 1 a-1 c can be obtained by forming retaining wall strips and then forming openings on the retaining wall strips at positions corresponding to the pad contacts 122, or by using a mask to form the retaining walls in one step. In addition, the blocking wall 123 in this embodiment may also be a strip structure with a constant width, and is disposed around the pad contact 122, as shown in fig. 1 d.
Fig. 2a is a schematic cross-sectional view of another touch display panel along a dashed line AB in fig. 1a, and fig. 2b is a schematic cross-sectional view of another touch display panel along a dashed line CD in fig. 1 a. In this embodiment, the retaining wall includes a first retaining wall portion 1232 and a second retaining wall portion 1231. Unlike fig. 1b and fig. 1c, in the present embodiment, the blocking wall is disposed on the second substrate 112 and has a gap d with the first substrate 111. It is to be noted that, in order to more clearly describe the arrangement of the retaining walls, the cross-sectional structure diagram in the embodiment does not show the touch electrode structure.
As shown in fig. 2a and 2b, the first and second blocking wall portions 1232 and 1231 include a black matrix layer 114 on a side of the second substrate 112 adjacent to the first substrate 111, and a supporting spacer layer 116 on a side of the black matrix layer 114 adjacent to the first substrate 111.
Alternatively, the black matrix layer 114 in the retaining wall is formed at the same time as the black matrix layer 114 in the display region 110, and the supporting spacer layer 116 in the retaining wall is formed at the same time as the supporting spacer layer 116 in the display region 110.
It should be noted that, in practical production, the first substrate 111 and the second substrate 112 are connected to form the touch display panel 100 after being respectively completed, the black matrix layer 114 is disposed on the second substrate 112, and the supporting spacer layer 116 is also generally disposed on the second substrate 112, so that, in order to form the retaining wall without increasing the process, in this embodiment, corresponding structures are simultaneously formed at the reserved positions of the retaining wall when the black matrix layer 114 and the supporting spacer layer 116 in the display region 110 are formed, and then the retaining wall is formed by stacking. It should be noted that the sum of the thicknesses of the black matrix layer 114 and the supporting spacer layer 116 is generally smaller than the distance between the first substrate 111 and the second substrate 112, so that a gap d exists between the retaining wall formed in the above manner and the first substrate 111, and the size of the gap d is limited to the case that glass debris cannot enter between the first substrate 111 and the second substrate 112, specifically, d is greater than or equal to 0 and less than or equal to 250 μm.
It should be noted that the retaining wall may also be a laminated structure of other films on the premise that the gap d between the retaining wall and the first substrate 111 satisfies the above condition. For example, the retaining wall may be a stacked color-resisting structure 117, and optionally, the color-resisting structure 117 of the retaining wall is formed at the same time as the color-resisting structure 117 in the display area 110, as shown in fig. 2c and fig. 2 d.
Fig. 3a is a schematic cross-sectional view of another touch display panel along the dashed line AB in fig. 1a, and fig. 3b is a schematic cross-sectional view of another touch display panel along the dashed line CD in fig. 1 a. In this embodiment, the retaining wall includes a first retaining wall portion 1232 and a second retaining wall portion 1231. Unlike fig. 2a and 2b, in the present embodiment, the blocking wall is disposed on the first substrate 111 and has a gap e with the second substrate 112. It is to be noted that, in order to more clearly describe the arrangement of the retaining walls, the cross-sectional structure diagram in the embodiment does not show the touch electrode structure.
It should be noted that the retaining wall may also be a multi-layer stacked structure when disposed on the first substrate 111, except that the stacked layer is a layer structure disposed on the first substrate 111.
It should be noted that, the thicknesses of the layers on the first substrate 111 and the second substrate 112 may vary according to the design and the actual production conditions, and therefore, the thickness of the dam may be smaller than or equal to the distance between the first substrate 111 and the second substrate 112 no matter the dam is disposed on the first substrate 111 or the second substrate 112. On the premise that the glass debris cannot pass through the gap between the retaining wall and the first substrate 111 or the second substrate 112, the thickness of the retaining wall is not particularly limited as long as the thickness of the retaining wall is not greater than the distance between the first substrate 111 and the second substrate 112.
Optionally, a liquid crystal layer may be disposed between the first substrate 111 and the second substrate 112 of the touch display panel in the invention, and the touch display panel is a liquid crystal touch display panel.
Optionally, an organic light emitting layer may be further disposed between the first substrate 111 and the second substrate 112 of the touch display panel, and the touch display panel is an organic light emitting touch display panel.
It should be noted that, although the light emitting principles of the liquid crystal touch display panel and the organic light emitting touch display panel are different, in the present invention, the retaining walls are disposed in the same manner, and the retaining walls can prevent glass debris from entering between the first substrate 111 and the second substrate 112 in the non-display region 120 where the pad contacts 122 are located.
Optionally, the touch display panel in the invention may also be a non-heterogeneous touch display panel. For example, fig. 4 is a schematic top view structure diagram of another touch display panel provided in the embodiment of the present invention. As shown in fig. 4, the touch display panel 300 includes a display region 110 and a non-display region 120 surrounding the display region 110, and further, the touch display panel 300 includes a second substrate 112, a touch electrode (not shown), a frame-shaped sealing structure 121, a pad contact 122 and a retaining wall 123, where the first substrate 111 and the second substrate 111 are disposed opposite to each other, the retaining wall 123 is disposed at an outer side of the frame-shaped sealing structure 121, and the touch display panel 300, the frame-shaped sealing structure 121 and the display region 110 are rectangular.
It should be noted that, as in the heterogeneous touch display device, the touch electrodes (not shown) and the pad contacts 122 of the touch display panel 300 in the embodiment are located on the side of the second substrate 112 away from the first substrate 111, and the touch electrodes (not shown) are electrically connected to the pad contacts 122. The frame-shaped sealing structure 121 and the retaining wall 123 are disposed between the first substrate 111 and the second substrate 112.
It should be further noted that glass fragments are generated when the touch display panel 300 is cut, and the retaining wall 123 can prevent the glass fragments from entering into a gap between the first substrate 111 and the second substrate 112 in the non-display area 120 where the pad contact 122 is located, so that the glass fragments are not forced to be pressed down in the binding process of the touch flexible printed circuit board, thereby avoiding the breakage of metal wires on the first substrate 111, and improving the production yield of products and the stability of the touch display panel 300.
Fig. 5 is a schematic structural diagram of a touch display device according to an embodiment of the invention, and as shown in fig. 5, the touch display device 400 includes a touch display panel 410 according to any embodiment of the invention.
The touch display device 400 provided by the embodiment of the invention adopts the touch display panel 410 described in any embodiment of the invention, and the retaining wall structure arranged in the touch display panel 410 prevents glass debris generated when the touch display panel 410 is cut from entering between the first substrate and the second substrate in the non-display area where the pad contact is located, so that the problem of metal wire breakage caused by the fact that the glass debris is pressed down under force in the binding process of the touch flexible printed wiring board is avoided, the display effect of the touch display panel 410 is improved, and the display performance of the touch display device 400 is improved.
