JP 2008-288801 A

  However, in the conventional display device, the frame member that holds the display panel is fixed to the cover member or formed integrally with the frame member. A front plate is attached so as to close the opening of the cover member in a state where the display panel is held by the frame member. Therefore, the display surface of the display panel is exposed until the front plate that covers the display surface of the display panel is assembled.

  In addition, as in the conventional display device described above, a peripheral device such as an antenna element or a camera is attached around the display panel. Therefore, it is necessary to attach various parts before attaching the front plate to the cover member, and the display panel is exposed for a long time. As a result, there is a high possibility that dust such as dust or dust adheres to the display surface of the display panel while the front plate is attached to the cover member.

  Further, the front plate and the cover member are fixed by engaging an engaging portion and an engaging receiving portion provided on the outer periphery of each. And the outer periphery vicinity of the display panel in the front plate was not fixed. Therefore, the vicinity of the display panel on the front plate is easily bent in a direction orthogonal to the surface direction. As a result, since the front plate is bent, a gap is generated between the display panel and the front plate, and there is a possibility that dust, dust, or the like may enter from the gap.

  In order to prevent the front plate from being bent, a method in which a fixing hole is provided near the outer periphery of the display panel of the front plate and fixed to the cover member using a fixing screw is conceivable. However, in such a configuration, since it is necessary to provide a fixing hole in the appearance surface of the front plate, there is a problem that the aesthetic appearance of the device is impaired.

  In the conventional configuration, when removing the cover member and the peripheral device, it is necessary to remove all of the front plate, the display panel, and the peripheral device. For this reason, the work of exchanging parts such as changing the color of the cover member or changing the peripheral device has become very complicated.

  In view of the above problems, an object of the present invention is to provide a display device and a display device assembly method that can prevent dust and dirt from adhering to the display surface of the display panel and can increase the rigidity of the entire device. It is in.

  In order to solve the above problems and achieve the object of the present invention, the display device of the present invention has the following configuration. The display device includes a display panel capable of displaying an image, a front plate covering the display surface of the display panel, and a cushion member attached to the front plate and interposed between the display surface of the display panel and the front plate. ing. In addition, a frame member is provided that covers a back surface portion and a side surface portion opposite to the display surface of the display panel and is fixed to the front plate in a state where the display panel is held. A cover member is disposed on the back surface side opposite to the display surface of the display panel and is attached to the front plate to which the frame member is fixed, and covers the frame member holding the display panel.

The method for assembling the display device of the present invention includes the following steps (1) to (5).
(1) The process of attaching a cushion member to the front plate which covers the display surface of the display panel which can display an image.
(2) A step of fitting the display panel into a recess provided in the frame member and covering the back surface portion and the side surface portion on the opposite side of the display surface of the display panel with the frame member.
(3) A step of fixing the frame member fitted with the display panel to the front plate and covering the display surface of the display panel with the front plate.
(4) A step of attaching a peripheral device to the front plate to which the frame member is fixed.
(5) A step of covering the frame member and the peripheral device by fixing the cover member to the front plate which is disposed on the back surface side opposite to the display surface of the display panel and to which the frame member and the peripheral device are fixed.

  According to the display device and the display device assembly method of the present invention, the display panel is held between the front plate, the frame member, and the cushion member by holding the display panel on the frame member and then fixing the display panel to the front plate. be able to. In addition, the time for which the display surface of the display panel is exposed during the assembly work can be shortened, and the time for dust or dirt to adhere to the display surface can be shortened. In addition, since the dustproof property of the display panel can be ensured before the step of attaching the peripheral device or the cover member, the operation of attaching the peripheral device or the cover member can be performed in a normal environment outside the clean room.

  In addition, by fixing the front plate, the display panel, and the frame member together, the rigidity of the entire apparatus is increased and the front plate is prevented from being bent. Therefore, it is possible to prevent a gap from being generated between the front plate and the display panel. As a result, it is possible to prevent dust and dirt from adhering to the display surface of the display panel during assembly work or after assembly is completed.

  Furthermore, since only the cover member can be removed without disassembling the display panel, the frame member, and the front plate, it is possible to easily change the cover member such as changing the color of the cover member.

It is sectional drawing which expands and shows the principal part.

  As shown in FIG. 4, the frame member 13 is formed in a thin container shape with one surface opened. The frame member 13 has a main surface portion 13a formed in a substantially rectangular shape, and side walls 13b, 13c, 13d, and 13e surrounding the main surface portion 13a.

  The first side wall 13b and the second side wall 13c disposed on both sides in the longitudinal direction of the main surface portion 13a and the third side wall 13d disposed on one side in the short side direction are substantially perpendicular to the main surface portion 13a. ing. And the 4th side wall 13e arrange | positioned at the other side of the transversal direction of the main surface part 13a bend | folds in the circular arc shape from the other end of the transversal direction of the main surface part 13a, and is continuing. The area of the main surface portion 13 a is set to be approximately the same as the area of the display panel 10.

  Then, the display panel 10 is fitted into the recess formed in the frame member 13. Thereby, the display panel 10 is held by the frame member 13. Although not shown, a second cushion member is provided on at least one of the side surface portion of the display panel 10 or the side walls 13b, 13c, 13d, and 13e of the frame member 13. The second cushion member urges the display panel 10 toward the side walls 13b, 13c, 13d, and 13e of the frame member 13, and eliminates the gap between the display panel 10 and the frame member 13. As a result, shakiness caused by a dimensional error between the display panel 10 and the frame member 13 can be removed.

  The first side wall 13b and the second side wall 13c are provided with a fixing portion 34 for fastening the fixing screw 41. As shown in FIG. 5, the fixing portion 34 is provided at a location corresponding to the screw portion 28 b provided in the frame member 20 when the frame member 13 is fixed to the front plate 11.

  The fourth side wall 13e is provided with an engagement receiving portion 35 that engages with an engagement claw 28a disposed on the other side of the frame member 20 in the short direction. Although not shown in the drawings, the first side wall 13b, the second side wall 13c, and the third side wall 13d are also formed with engagement receiving portions 35 that engage with the engagement claws 28a provided on the frame member 20.

  As shown in FIG. 5, the frame member 13 is fixed to the frame member 20 by fastening and fixing with the fixing screw 41 and the engagement claw 28 a and the engagement receiving portion 35 while the display panel 10 is held. Thereby, the display panel 10, the front plate 11, and the frame member 13 are fixed integrally. In this way, by integrating the front panel 11, the display panel 10, and the frame member 13, it is possible to regulate bending and twisting in the direction orthogonal to the surface direction of the front panel 11, and the entire display unit 3 can be controlled. Stiffness can be increased.

  Here, the front plate 11 is fixed to the frame member 13 at the periphery of the opening 22. Therefore, the strength of the peripheral portion of the opening 22 of the front plate 11 can be increased, and the peripheral portion of the opening 22 in the front plate 11, that is, the vicinity of the outer periphery of the display panel 10 in the front plate 11 can be prevented from bending. Can do. Thereby, when the front plate 11 is bent, a large gap is generated between the front plate 11 and the display panel 10, and dust and dust can be prevented from entering the display surface 10a side of the display panel 10. .

  In this example, as an example of the fixing method of the frame member 13 and the front plate 11, the fixing screw 41 and the engaging claw 28a are used. However, the present invention is not limited to this. For example, the frame member 13 and the front plate 11 may be fixed with only the fixing screw 41. When only the fixing screw 41 is used for fixing, the frame member 13 and the front plate 11 can be firmly fixed and the assemblability can be improved as compared with the case where the fixing claw 28a is used for fixing.

  Alternatively, the frame member 13 and the front plate 11 may be fixed only by the engaging claws 28a. When it fixes only with the engagement nail | claw 28a, the magnitude | size of a fixing | fixed part can be made small and the area which mounts a peripheral device and the magnitude | size of the display panel 10 can be enlarged.

  In addition, as shown in FIG. 6A, the display panel 10 is disposed between the frame member 13 and the front plate 11. And the display surface 10a of the display panel 10 faces from the opening part 22 of the front plate 11. FIG.

  Furthermore, the back surface portion of the display panel 10 is covered with the main surface portion 13a of the frame member 13, and the side surface portion of the display panel 10 is covered with the side walls 13b, 13c, 13d, and 13e of the frame member 13. Further, the display surface 10 a of the display panel 10 is covered with the front plate 11. Therefore, the display panel 10 is sealed in a space P formed by the front plate 11, the frame member 13, and the first cushion member 14 (see FIG. 6B). Thereby, it is possible to prevent dust and dust from entering between the display surface 10 a of the display panel 10 and the clear panel 21 of the front plate 11.

  As shown in FIG. 6B, a first cushion member 14 is interposed between the display panel 10 and the frame member 20. Here, the display panel 10 is pressed against the first cushion member 14 side by fixing the frame member 13 to the front plate 11. Therefore, the outer edge of the display surface 10a of the display panel 10 and the first cushion member 14 are in close contact with each other. Thereby, it can prevent more effectively that dust and dust adhere to the display surface 10a of the display panel 10. FIG.

  Examples of the material of the frame member 13 having the above-described configuration include metal materials such as magnesium alloy and stainless steel. The frame member 13 may be formed of engineer plastic.

FIG. 7 is a perspective view showing a state in which peripheral devices are mounted on the front plate 11.
As shown in FIG. 7, a peripheral device including antenna elements 15 and 15, a camera module 16, a second input unit 17, and the like is mounted on the frame member 20 of the front plate 11. The two antenna elements 15 each have an antenna portion 15a capable of transmitting and receiving radio waves, and a ground plate (hereinafter referred to as “GND plate”) 15b connected to the antenna portion 15a. Moreover, the wiring 15c is connected to the antenna part 15a.

  The two antenna elements 15, 15 are arranged one by one on the first installation part 23a and the second installation part 23b. The GND plate 15 b of the antenna element 15 is in contact with the main surface portion 13 a of the frame member 13. As a result, the antenna element 15 is grounded. When the antenna element 15 is provided as a peripheral device, the frame member 13 is preferably made of a metal material such as a magnesium alloy in order to perform grounding.

  Here, in the conventional display device 100 shown in FIG. 10, the GND plate 104 b of the antenna element 104 is disposed on the back side of the display panel 101 over the rib 105. In order for the GND plate 104b to easily get over the rib 105, it is necessary to provide a cutout in the rib 105. Therefore, in the conventional display device 100 as shown in FIG. 10, the height of the rib 105 is partially reduced, and the side surface of the display panel 101 cannot be completely held. As a result, the strength of the entire apparatus has been reduced.

  Further, by providing the notch in the rib 105, stress concentrates on the notch, and a large force is easily applied to the display panel 101. And the location which provided the notch may become a starting point when a crack arises in the display panel 101. FIG.

FIG. 8 is a cross-sectional view of the display unit 3 shown in FIG. 1 taken along line NN.
As shown in FIG. 8, the GND plate 15 b of the antenna element 15 of the display unit 3 of this example is in contact with the surface of the main surface portion 13 a of the frame member 13 opposite to the surface facing the display panel 10. Therefore, unlike the conventional GND plate 104b of the antenna element 104, it is not necessary to get over the rib 105, so that the side walls 13b, 13c, 13d, and 13e of the frame member 13 do not have to be provided with a notch. Therefore, the height of the side walls 13b, 13c, 13d, and 13e can be set to the same length over the entire circumference. Thereby, since there is no location where stress concentrates on the frame member 13, the starting point of the crack of the display panel 10 can be eliminated.

  Then, the height of the side walls 13b, 13c, 13d, and 13e of the frame member 13 can be increased to the limit within the range of the thickness of the display unit 3. Therefore, the side surface portion of the display panel 10 can be reliably covered with the side walls 13b, 13c, 13d, and 13e of the frame member 13. As a result, the display panel 10 can be strongly protected, and dust and dust can be effectively prevented from entering the display surface 10a side of the display panel 10.

  Returning to FIG. 7, the second input unit 17 includes a second key type input unit 18 including two keys and a touch panel type touch input unit 19. Examples of the input method of the touch input unit 19 include a capacitance method and a resistance film method.

  The second key type input unit 18 is mounted on the first installation unit 23a. And the 2nd key type input part 18 faces from the 1st operation window 24 provided in the 1st installation part 23a, and the exposure window 30 of the clear panel 21 (refer FIG. 1). The touch-type input unit 19 is installed in the second installation unit 23b so as to face the second operation window 25 provided in the second installation unit 23b.

  The second key type input unit 18 and the touch type input unit 19 are connected via a flat cable (FFC: Flexible flat cables) 31. The second key type input unit 18 and the touch type input unit 19 are connected to the main body unit 2 side by wiring extending from either the second key type input unit 18 or the touch type input unit 19.

  Furthermore, the camera module 16 is mounted on the second installation portion 23b. The camera module 16 is disposed between the antenna unit 15 a of the antenna element 15 and the touch input unit 19. The lens portion of the camera module 16 faces the imaging window 26 provided in the second installation portion 23b.

  Moreover, the hinge part 4a which comprises the hinge mechanism 4 is attached to the both sides of the other end of the transversal direction of the main surface part 13a. One end of the hinge portion 4 a is fixed to the display portion 3, and the other end is fixed to the main body portion 2. And one end and the other end of this hinge part 4a are connected so that rotation is possible. Therefore, the display unit 3 and the main body unit 2 are rotatably connected by the hinge unit 4 a constituting the hinge mechanism 4.

  The cover member 12 is formed in a container shape having a substantially rectangular shape. The cover member 12 has a central portion that bulges in a direction opposite to the front plate 11 and a peripheral portion that is rounded. Further, a fixing claw (not shown) is provided on the outer edge of the cover member 12. Note that an engagement receiving portion (not shown) is provided on the outer periphery of the front plate 11. The fixing claw of the cover member 12 engages with an engagement receiving portion provided on the outer periphery of the front plate 11.

  As shown in FIG. 8, the cover member 12 is disposed on the side opposite to the appearance surface of the front plate 11 and is detachably attached to the back side of the front plate 11. The cover member 12 covers the frame member 13, the display panel 10, the two antenna elements 15 and 15, the camera module 16, and the second input unit 17.
