Description

  The present invention relates to a cover device disposed on a display unit (display surface) of a display panel, and a display device-equipped display panel including the cover device.

At present, various image display devices (hereinafter simply referred to as “display devices”) such as audio visual (AV) devices, mobile phones, pocket computers, electronic books, and personal digital assistants (PDAs) capable of searching for Internet information as small electronic devices. Has been developed and popularized.
Many of these display devices are originally developed from stationary electronic devices for small and portable applications. With the spread of the Internet connection environment, the size and capacity of recording media, and the miniaturization of parts, the number of functions is increasing.

  In particular, in recent years, the number of products that support audio functions for listening to music and recorded audio and display functions for viewing moving images and still images has increased significantly, and display devices with display surfaces with excellent image display performance have expanded rapidly. Yes. As a typical display device, a so-called display panel having a display unit such as a liquid crystal display (LCD) or an organic EL display (OELD) has been developed.

  The display panel is capable of full-color display, and it is convenient for the user to easily grasp the information. On the other hand, there is a problem that when the user carries the display panel, the display unit is easily damaged by dropping, impact, excessive pressing, or the like. In particular, recently, display panels having a large display unit and particularly improved image display performance have been rapidly commercialized, and it is required to appropriately protect display panels having such a large display unit. Yes.

  On the other hand, conventionally, as shown in the display device of Patent Document 1, for example, a configuration in which a slide-type cover is provided on the housing of the display device has been proposed. In this configuration, the display unit is covered and protected when not in use, and when in use, the cover is slid to another area on the surface of the housing and retracted to expose the display unit to the outside.

JP 2006-31348 A

However, since the cover of Patent Document 1 and the like slides as it is on the surface of the casing (retreat area) other than the display unit when in use, a dead space larger than the area of the cover must be provided as a retreat area in advance on the surface of the casing. Don't be. This dead space cannot contribute to image display or operation because of its structure.
Here, since the size of the cover is set in proportion to the area of the display unit to be protected, the retreat area increases as the display unit becomes larger. Accordingly, it is necessary to provide a large retreat area on the surface of the housing. Further, when the cover is retracted, a part of the operation buttons existing in the retreat area may be covered, which may cause a problem that certain operations cannot be performed.

The existence of such a dead space is a major limitation in reducing the size of the display panel, which is a major problem in terms of improving the effective screen ratio of the display unit and achieving both a large display panel and portability. It becomes.
The present invention has been made in view of the above problems, and appropriately protects the display surface from the outside when not in use, prevents the occurrence of cracks and scratches, and effectively suppresses the occurrence of dead space during use. An object of the present invention is to provide a cover device that can be expected to improve the effective screen ratio and a display panel with a cover device using the same.

  In order to solve the above-described problem, one aspect of the present invention is a cover device that covers the display surface of a display panel having a display surface on one main surface, and is in a state in which the display panel moves freely and extends. A cover body that covers at least a part of the display surface; and a fastening portion that is fastened to the display panel at one end of the cover body, and covers the display surface by extending the cover body from the one end side. The first state and the second state in which the cover body is contracted by approaching the fastening portion from the opposite direction to the one end side.

According to the cover device of the present invention, in the first state, the display surface of the display panel is covered by extending the stretchable cover body, and the display surface is appropriately protected. Thereby, even if a display device having a large display surface is carried outside, it is possible to effectively prevent the display surface from cracking or being damaged by contact with the outside.
On the other hand, in the second state, the cover body is contracted by a user operation and retracted to an area other than the display surface on the one main surface. As described above, according to the present invention, when the panel is used, the retracted area can be made as small as possible by retracting the cover body while retracting it while exposing the display surface. As a result, it is possible to contribute to downsizing the casing of the display panel without impairing the portability and operability of the display panel. In addition, it is possible to secure a large display area in the display panel, improve the effective screen ratio, and contribute to the enlargement of the screen.

  As described above, according to the present invention, it is possible to suppress the generation of cracks and scratches on the display surface due to pressing and dropping while achieving both portability of the display panel and a large screen.

<Embodiment 1>
(Configuration of display device 1 with cover device)
FIG. 1A is a diagram showing a schematic configuration of a display device 1 with a cover device (hereinafter simply referred to as “display device 1”), which is an example of the present invention. The display device 1 includes a portable information terminal 20 and a cover device 10 disposed on the portable information terminal 20.

  The portable information terminal 20 is a smartphone that is a typical small display device. It has a flat, thin rectangular parallelepiped housing having a first main surface (front surface) 201 and a second main surface (back surface) 202. On the first main surface 201, a large rectangular display unit (display surface 203) including a liquid crystal display or an organic EL display, an operation unit 204, and a speaker unit 200 are arranged. The second main surface 202 is not illustrated as a whole, but is formed of a smooth curved surface so as to be continuous with the first main surface 201.

  Note that the “display panel” in the present specification basically refers to a panel having a thin casing such as the portable information terminal 20, but is not limited to such a configuration, and has a certain thickness in the Z direction. All display devices such as a rectangular parallelepiped shape, a semi-cylindrical shape, and a polygonal column shape are included in the “display panel”. Further, the “cuboid” does not need to be a strict hexahedron, and even if some of the side surfaces sandwiched between the first main surface 201 and the second main surface 202 have a gentle shape like the portable information terminal 20. Good.

The cover device 10 is provided on a guide member (a pair of guide rails 101a and 101b) extended in the X direction, a cover body 102 provided across the pair of guide rails 101a and 101b, and one end side of the cover body 102. It is comprised with the fixed part 1023 made. In addition, the cover apparatus 10 should just be provided with the cover body 102 and the fastening part 1023 at least.
The guide rails 101a and 101b are guide members that guide the cover body 102 in one direction (here, the direction along the X axis) along the surface of the first main surface 201 of the portable information terminal 20, and FIG. ), The guide grooves 1010a and 1010b are formed so as to face the cover body 102 along the Y-axis direction.

  In the first embodiment, the cover body 102 includes an elongate cover body 1021, a slide shaft (sliding body) 1021c arranged to project from each valley fold 1021b in the Y direction, and one end in the longitudinal direction of the cover body 1021. It is composed of a knob 1022 provided on the side and a magnet portion 1025. As the slide shaft 1021c, a known bare link shaft or roller shaft may be used in addition to the metal shaft. The cover body 102 only needs to include at least the cover body 102.

  The cover main body 1021 is a bellows-like body (here, a sheet-type accordion-like body) having a plurality of fold-folded portions 1021a and valley-folded portions 1021b. For example, a sheet material (natural material such as cotton) having excellent flexibility and mechanical strength. Fiber, synthetic fiber such as polyester, vinyl chloride resin, urethane resin, or the like). The material is not limited to this, and in consideration of texture, operability, and aesthetics, in addition to cardboard, Japanese paper, leather material, PET resin, a rubber material having a stretchable material itself can be used.

  The cover body 1021 covers the entire display surface 203 of the first main surface 201 using the bellows-like form when it is used and protects it from the outside, and shrinks to a compact shape when not in use. 203 can be retreated. In addition, although the protective effect of the display surface 203 is improved by using a hard material for the material of the cover main body 1021, it should be noted that if it is too hard, it may be difficult to expand and contract.

The covering size of the cover body 102 may be a covering size that covers at least a part of the display surface 203, but in view of effectively protecting the display surface 203, the covering size is as large as possible or larger than the size of the display surface 203. The size is preferred.
Here, the cover main body 1021 is integrally formed, but the present invention is not limited to this. For example, a plurality of strip members may be connected by hinges or the like at each of the mountain folded portions 1021a and the valley folded portions 1021b. Is possible.

  When the cover device 10 is provided, the guide rails 101a and 101b are passed through the outer side of one side of the rectangular display surface 203 along the X direction and the outer side of the one side with respect to the portable information terminal 20. Is disposed using a double-sided tape or an adhesive. Then, the cover main body 1021 is interposed between the guide rails 101a and 101b, and the guide pins 1021c are slidably carried inside the guide grooves 1010a and 1010b. Further, the fastening portion 1023 is fixed below the first main surface 201 with a double-sided tape or an adhesive.

(Effect of display device 1)
The state of the display device 1 having the above configuration will be described with reference to FIGS. 1 (a) and 1 (b) and FIGS. 2 (a), 2 (b) and 2 (c).
When the display device 1 is not used (first state), as shown in FIGS. 1B and 2B, the user uses a knob 1022 provided on one end side in the longitudinal direction of the cover body 1021. Then, the cover body 102 is pushed up in the reverse X direction with a finger. As a result, the cover body 102 is guided by the guide rails 101 a and 101 b and slides in the reverse X direction along the surface of the first main surface 201 of the portable information terminal 20. The user continues to move the cover body 102 and moves to a position where the display surface 203 is covered. When the sliding amount is maximized, the magnet portion 1025 provided at the tip of the cover body 102 is attracted to the magnet portion 1024 provided on the display surface 203, and the cover body 102 is held in position. As a result, the display surface 203 completely covered with the cover body 102 is appropriately protected by the cover body 102 from external impacts and cracks and scratches due to excessive pressing (FIG. 2B).

In addition, when the display surface 203 is a touch panel type, it is possible to prevent malfunctions and erroneous inputs from occurring by covering the display surface 203 with the cover body 102 when not in use.
In addition, the cover body 102 can be expected to prevent malfunctions and erroneous inputs to the operation unit 204.
On the other hand, when the display device 1 is used (second state), the user pushes down the cover body 102 in the X direction with a finger to expose the display surface 203 (FIG. 1A). At this time, the cover body 102 is smoothly guided along the guide rails 101a and 101b and is slid in the X direction (FIGS. 1A and 2C). At this time, the cover body 102 is folded and contracted at the mountain fold portion 1021a and the valley fold portion 1021b, and is retracted to the lower region of the display surface 203 in a more compact shape than the first state.

As described above, since the cover body 102 can be retracted in a small area when in use, the portable information terminal 20 can be downsized and the effective screen ratio can be improved.
Furthermore, in any of the above operations, the cover body 102 can be smoothly slid by the slide shaft 1021c carried on the guide rails 101a and 101b. Therefore, switching between the first state and the second state is very easy. It can be done freely with the user's one-handed operation. Even during the operation of the cover device 10, the operability of the side operation unit 205 is not hindered, so that the user can freely operate the side operation unit 205.

Such various effects cannot be obtained by the conventional technology such as Patent Document 1 in which a hard cover having a fixed slide amount is provided.
In addition, the cover apparatus 10 in the display device 1 is a product that can be detached from the portable information terminal 20 independently, and can be applied to various display devices other than the portable information terminal 20.

In the above example, the cover body 102 is completely retracted from the display surface 203 in the second state. However, in the first state, the display surface 203 is partially covered with the cover body 102, and in the second state, the cover body 102 is retracted to such an extent that the exposed area of the display surface 203 is smaller than that in the first state. May be. Even in this case, a certain protective effect for the display surface 203 can be expected. However, it should be noted that at least operability, display characteristics, and protection performance of the display surface 203 are not impaired.
<Embodiment 2>
FIG. 3A is a diagram schematically showing the structure around the cover device 10A according to the second embodiment. The cover device 10A has a configuration in which the pair of guide rails 101a and 101b and the guide pin (sliding body) 1021c are omitted from the cover device 10.

  Even in the cover device 10A having such a configuration, it is possible to expect the same effect as the cover device 10 by operating the cover body 102A. That is, when not in use, the cover 102 can be extended and expanded with respect to the display surface 203 of the portable information terminal 20 in FIG. 1 to appropriately protect the display surface 203 from the outside, and the display surface is cracked by pressing or dropping. And the generation of scratches can be suppressed.

Further, when the display surface (not shown) is a touch panel type, it is possible to prevent the occurrence of malfunctions and erroneous input problems by covering with a cover body 102A when not in use.
In addition, the cover body 102 </ b> A can be expected to have an effect of preventing erroneous operation / incorrect input to the operation unit (not shown).
On the other hand, in use, the cover body 102A can be compactly contracted on the first main surface 201, and the occurrence of excessive dead space can be effectively prevented.

Here, as shown in FIG. 3B, which is a side view, the magnet unit 1026 is provided at the lower part (lower part in the X direction) of the operation unit 204, and is completely used during use as shown in FIG. It is also preferable that the retracted cover body 102A is fixed by being attracted to the magnet portion 1025 of the cover device 10A that has been retracted and retracted.
The folding direction of the cover body 102A is not limited to the X direction parallel to the plane of the display surface (first main surface) as shown in FIG. 3B, and the plane of the display surface (first main surface) It may be folded in the vertical Z direction.

In the first and second embodiments, the cover bodies 102 and 102A are folded. However, when the cover bodies 102 and 102A are formed into a sheet shape from a flexible material such as a resin film, cloth, or fiber material, a roll is used during use. It is also possible to take it up and retract from the display surface.
<Embodiment 3>
Next, FIG. 4 is a diagram illustrating a schematic configuration of the cover apparatus 10B according to the third embodiment.

  The cover device 10B includes a blind curtain-like cover body 102B and a frame body 101f surrounding the cover body. A plurality of strip members (slat portions 1027) are arranged at regular intervals and are connected to each other by connecting yarns 1028a and 1028b provided near both ends in the longitudinal (Y) direction. A knob 1022 and a magnet portion 1025 are disposed on the slat portion 1027a at the end in the extending direction.

The frame body 101f serves to guide the expansion and contraction of the blind curtain cover body 102B, and is disposed using a double-sided tape, an adhesive, or the like so as to surround the display surface 203 of the belt information terminal 20. Each slat part 1027 is accommodated in the frame 101f.
Further, as shown in FIG. 4, each of the slat portions 1027 and the frame body 101f is provided with two holes 1027b and 1010c, respectively, and a retracting thread 1029 is inserted into the holes 1027b and 1010c in a U shape. . Both ends of the retracting yarn 1029 are fixed to the slat portion 1027a at the end in the extending direction. In the cover device 10B, the retracting thread 1029 and the frame body 101f function as a fastening portion that fastens the cover body 102B to the portable information terminal 20 side.

With the above configuration, when the retracting thread 1029 is pulled out from the frame body 101f in use, the slat portions 1027 and 1027a are pulled in the X direction, and the interval between the slat portions 1027 and 1027a is shortened and contracted as a whole. As a result, an opening region is generated inside the frame 101f, and the display surface 20 is exposed to the outside through the opening region.
On the other hand, when the user slides the knob 1022 in the reverse X direction when not in use, the slat portions 1027 and 1027a are drawn out at predetermined intervals, and the slat portions 1027 and 1027a are in a lying posture, and the display surface 20 is moved. It can be covered and protected (in FIG. 4, slat portions 1027 and 1027a are set up for explanation). In addition, by covering with the slat portions 1027, 1027a,
It is adequately protected from cracks and scratches caused by external impact and excessive pressure.

In addition, when the display surface (not shown) is a touch panel type, it is possible to prevent the occurrence of malfunctions and erroneous inputs by covering with a cover body 102B when not in use.
In addition, the cover body 102B can be expected to have an effect of preventing erroneous operation / incorrect input to the operation unit (not shown).
The magnet portion 1025 disposed on the slat portion 1027a is attracted to the magnet portion 1024 (see FIG. 1A) provided at the upper portion of the display surface 203, so that the position of the cover body 102B is favorably maintained. The
<Embodiment 4>
Next, FIG. 5 is a partial perspective view schematically showing a structure around the cover device 10C according to the fourth embodiment.

The cover device 10C includes a pair of guide rails 101a and 101b and a pay-out type cover body 102C.
For example, the cover body 102 </ b> C includes a plurality of plate-like members 1020 a to 1020 f formed using a resin material (such as polycarbonate) having a certain mechanical strength. As shown in FIG. 5, the plate-like members 1020a to 1020f are arranged so as to overlap each other in the same order from top to bottom. Hanging portions 1028a to 1028f extending in the Z direction are erected on one side (here, one side on the far side in the reverse X direction) of the side surfaces along the longitudinal (Y) direction of the plate-like members 1020a to 1020f. The height of the hanging part 1028a is set to the total thickness of all the plate-like members 1020a to 1020f, and the heights of the other hanging parts 1028b to 1028f are reduced by the thickness of each plate-like member 1020a to 1020f in the same order. I am letting. Accordingly, when the uppermost plate-like member 1020a slides in the X direction, the hanging portions 1028a to 1028f of the adjacent plate-like members 1020a to 1020f come into contact with each other, and all the plate-like members 1020a to 1020f slide in the X direction. To do. Guide pins 1031a to 1031f are provided at both ends in the Y direction from the hanging parts 1028a to 1028f so as to protrude to the outside. The guide pins 1031a to 1031f may be formed integrally with the plate members 1020a to 1020f.

Also, ribs 1030b to 1030f are erected in the Z direction directly above the hanging portions 1028b to 1028f of the plate members 1020b to 1020f, and each plate member engages with a rib of the adjacent plate member immediately below. Thus, the first engagement portion is configured.
Further, of the side surfaces along the longitudinal (Y) direction of the plate-like members 1020b to 1020f, the other side (here, one side on the front side in the X direction) abuts the ribs 1030b to 1030f on the side surface when the cover body 102C is extended. Claw portions 1029a to 1029e that can be engaged with each other are formed, and the second engagement portion is configured by engaging each.

The pair of guide rails 101a and 101b is substantially the same as in the first embodiment, but restriction pins 1011a and 1011b are arranged so that the guide pins 1031a to 1031f do not fall off.
In the cover device 10 </ b> C having the above configuration, the payout-type cover body 102 </ b> C is disposed on both side surfaces along the X direction of the display surface 203 of the portable information terminal 20 with the pair of guide rails 101 a and 101 b in FIG. . As shown in FIG. 5, the guide pins 1031a to 1031f of the plate-like members 1020a to 1020f are inserted and arranged in the guide grooves 1010a and 1010b of the guide rails 101a and 101b. As described above, in the cover device 10C, the guide rails 101a and 101b and the guide pins 1031a to 1031f also serve as a fastening portion of the cover body 102C.

FIGS. 6A and 6B show the state before and after using the display device 1A in which the cover body 102C is disposed on the portable information terminal 20. FIG.
At the time of use, as shown in FIG. 6A, the user operates the knob 1022 of the plate-like member 1020a in the X direction. Accordingly, the plate-like members 1020a to 1020f are stacked on each other, slide in the X direction along the pair of guide rails 101a and 101b, and retract from the display surface 203. At this time, in the cover body 102C, the claws 1029a to 1029e and the ribs 1030b to 1030f are separated so that the plate-like members 1020a to 1020f are disengaged, slide independently of each other, and retract while being contracted as a whole. Therefore, the user can perform a quick operation when the display surface 203 is exposed, and can operate the operation unit 204 well and enjoy the display content of the display surface 203. Moreover, since the plate-like members 1020a to 1020f overlap in a compact manner and the apparent total area of the cover body 102C shrinks, the area of the dead space can be suppressed as much as possible, and the effective screen ratio in the display device 1A can be improved. .

  On the other hand, when not in use, as shown in FIG. 6B, the user operates the knob 1022 of the plate-like member 1020a in the reverse X direction. Accordingly, the plate-like members 1020a to 1020f are engaged with each other when the claws 1029a to 1029e and the ribs 1030b to 1030f come into contact with each other, and are sequentially drawn out in the reverse X direction. The cover body 102 </ b> C expands to increase the area, and finally covers the entire display surface 203. When the magnet portion 1025 disposed under the knob 1022 is attracted to the magnet portion 1024 provided on the upper portion of the display surface 203, the cover body 102C is positioned, and the display surface 203 is well protected from the outside. . Here, by forming the plate-like members 1020a to 1020f with a material having a certain mechanical strength, an excellent protective effect can be expected particularly for the display surface 203. In addition, malfunction and erroneous input of the display surface 203 and the operation unit 204 can be well prevented.

Note that the number of plate-like members is not limited to six, and may be, for example, about three.
In the third and fourth embodiments, a plurality of plate-like members are engaged with the claw portions and ribs. However, the claw portions and ribs are not essential and can be slid independently for each plate-like member. It can also be arranged. In this case, a gap may be generated between the plate-like members when the cover body is deployed when not in use, but the developed plate-like member can be expected to protect the display surface.
<Embodiment 5>
Next, FIG. 7 is a partial perspective assembly view schematically showing a structure around the cover device 10D according to the fifth embodiment. The basic structure of the cover device 10D is the same as 10C, and a cover body 102D composed of plate-like members 1034a to 1034f is slidably supported by a pair of guide rails 101c and 101d. The pair of guide rails 101c and 101d are provided with guide grooves 1012a to 1017a, 1012b to 1017b corresponding to the respective plate-like members 1034a to 1034f.

  Here, the plate-like members 1034a to 1034f do not use guide pins, and the planar end portions 1032a to 1032f and 1033a to 1033f at both ends in the longitudinal (Y) direction of the plate-like members 1034a to 1034f are guided grooves of the respective guide rails. It is inserted into 1012a to 1017a, 1012b to 1017b, and is slidably supported. Accordingly, the cover body 102D is directly fixed to the portable information terminal side by the pair of guide rails 101c and 101d.

Next, FIG. 8A is a perspective view schematically showing a configuration of a display device 1B according to Embodiment 5 including the cover device 10D.
The display device 1B is a so-called touch panel type information terminal, and the large display surface 214 of the main unit 213 housed in the thin casing 21 is connected to the outside through the opening 215 in the first main surface 216 of the casing 21. Exposed. Inside the housing 21, guide rails 101c and 101d (101d not shown) are disposed on a pair of side surfaces along the X direction of the display surface 214, respectively. The plate-like members 1034a to 1034f are slidably supported in the guide grooves 1012a to 1017a, 1012b to 1017b of the guide rails 101c and 101d.

  Even in this configuration, various effects similar to those of the fourth embodiment can be expected. That is, at the time of use, the user operates the knob 1022 to slide the cover body 102D in the X direction.
