[0009] Before specifically describing the embodiments of the present disclosure, an overview of the embodiments will be described. This embodiment relates to a display device mounted on a vehicle. In the display device, for example, a display panel is housed inside a chassis with an opening at the front side, and a frame-shaped frame (hereinafter referred to as a "front frame") is attached to the front opening of the chassis. Here, the front frame is a design part and a part that is touched by the hands of the occupants. The front frame is formed of resin. When the front frame and the chassis are separate structures, it is necessary to reduce the thickness of the front frame in order to narrow the frame. However, simply making the front frame thinner may make the front frame more likely to come off the chassis due to external forces such as vibration. Therefore, it is difficult to ensure at least one of the strength and rigidity of the display device. Therefore, in order to ensure strength and rigidity, the front frame is provided with a certain thickness. This may result in certain restrictions on the miniaturization of the product and the narrowing of the frame, which may reduce the freedom of design.
[0010] In order to ensure strength while narrowing the frame, for example, it is possible to insert mold the chassis and the front frame. This allows the display device to have a chassis-insert integrated structure in which the front frame is inserted into the chassis. When the chassis is manufactured by die casting, for example, the glass lens of the display panel is adhered to the chassis with an adhesive member. In the chassis-insert integrated structure, even if the front frame is thin, the front frame is less likely to come off the chassis due to external forces, so strength is ensured.
[0011] When manufacturing a chassis by die casting, it is necessary to renew the mold at a certain frequency. Considering the cost and versatility, it is desirable to manufacture the chassis by a method other than die casting. For example, a chassis can be manufactured using sheet metal. On the other hand, when a glass lens is bonded to a chassis with an adhesive member, a high flatness is required for the bonding surface with the glass lens. It is more difficult to ensure flatness with a chassis made of sheet metal than with a chassis made of die casting. If the flatness of the bonding surface between the glass lens and the chassis is low, the display panel may not be attached evenly to the chassis. This may cause black unevenness in the liquid crystal in the display panel, resulting in a decrease in contrast or deterioration in quality. In addition, if the flatness of the bonding surface is low, the adhesive member may easily peel off. Here, flatness refers to the degree of surface unevenness, warping, undulation, or distortion. The flatness is defined, for example, in JIS G 3193, but is not limited thereto. The flatness may be a flatness that is a value indicating the width of an object when it is sandwiched between two completely flat planes from above and below.
[0012] In the display device according to this embodiment, the front end of the chassis is covered with a front frame, and the glass lens is fixed to the chassis via the front frame. The front frame is made of resin, so the flatness of the mounting surface on which the glass lens is mounted can be increased. In the following description, "parallel" and "orthogonal" do not only mean completely parallel and orthogonal, but also include cases where the parallel and orthogonal orientations deviate from the parallel and orthogonal orientations within a margin of error.
[0013] FIG. 1 shows the structure of the interior of a vehicle 10. A windshield 52 is disposed in front of a dashboard 50 disposed at the front of the cabin. A steering wheel 54 is disposed on the right side of the dashboard 50, but the steering wheel 54 may be disposed on the left side of the dashboard 50. A center console 56 extending in the vertical direction is disposed in the center of the dashboard 50, and a display device 100 is fitted into the center console 56. Also, only the lower part of the display device 100 may be fitted into the center console, and the entire design of the display device 100 may be exposed to the outside. The display device 100 is included in an electronic device such as a navigation device. The display device 100 may be capable of displaying a map image or the like. The display device 100 may be a meter display disposed in front of the steering wheel.
[0014] 2(a)-(b) show the structure of the display device 100. As shown in FIG. 2(a)-(b), an orthogonal coordinate system including an x-axis, a y-axis, and a z-axis is defined. The x-axis and the y-axis are mutually orthogonal. The z-axis is perpendicular to the x-axis and the y-axis, and extends in the vertical direction of the display device 100. The positive directions of the x-axis, y-axis, and z-axis are defined as the directions of the arrows in FIG. 2(a)-(b), and the negative directions are defined as the directions opposite to the arrows. Here, the positive direction of the x-axis is sometimes called "forward" or "front side", the negative direction of the x-axis is sometimes called "rear" or "rear side", the positive direction of the y-axis is sometimes called "right side" or "right side", the negative direction of the y-axis is sometimes called "left side" or "left side", the positive direction of the z-axis is sometimes called "upper side" or "upper side", and the negative direction of the z-axis is sometimes called "lower side" or "lower side". Therefore, it can be said that the x-axis extends in the front-rear direction, the y-axis extends in the left-right direction, and the z-axis extends in the vertical direction.
[0015] FIG. 2(a) is a perspective view showing the appearance of the display device 100. FIG. 2(b) is a cross-sectional view of the display device 100 taken along line A-A' in FIG. 2(a). A plate-shaped glass lens 110 extending in the yz plane is disposed on the front surface of the display device 100. The glass lens 110 is a light-transmitting member and is formed of glass. Resin may be used for the glass lens 110 instead of glass, and the glass lens 110 may be called a transparent member. The peripheral portion of the glass lens 110 is surrounded by the front frame 120. The front frame 120 is, for example, rectangular. The front frame 120 may be round. The entire peripheral portion of the glass lens 110 may be surrounded by the front frame 120, or a part of the peripheral portion may not be surrounded by the front frame 120. For example, the upper side and the left and right sides of the peripheral portion of the glass lens 110 may be surrounded by the front frame 120, and another member may be attached to the lower side. The distance between the periphery of the glass lens 110 and the front frame 120 is defined as the frame width. Reducing the frame width corresponds to narrowing the frame. For example, the frame width is set to 10 mm or less.
[0016] The front frame 120 is disposed on a part of the front surface and a part of the side surface of the display device 100. A rear frame 130 is disposed on the rear side of the front frame 120 so as to cover the side surface and rear surface of the display device 100. In this way, the side surface and rear surface of the display device 100 are covered by the front frame 120 and the rear frame 130. The front frame 120 and the rear frame 130 are formed from resin. A material with sufficient breaking elongation or a material with a linear expansion coefficient close to that of the chassis 300 described below is used for the resin. This is to prevent cracking due to temperature changes.
[0017] Inside the display device 100 surrounded by the glass lens 110, the front frame 120, and the rear frame 130, a display panel 200 is disposed opposite the glass lens 110. An example of the display panel 200 is a liquid crystal panel. The display panel 200 emits display light toward the glass lens 110. The sides and rear of the display panel 200 are covered by a chassis 300. The chassis 300 is a sheet metal chassis and is made of iron. The front end of the chassis 300 is connected to the front frame 120. The front side of the front frame 120 is connected to the glass lens 110, and the rear side of the front frame 120 is connected to the rear frame 130.
[0018] In the following, FIG. 3 is also used to explain the structure of FIG. 2(b) in more detail. FIG. 3 is a partial cross-sectional view in which a part of FIG. 2(b) is enlarged. FIG. 3(a) shows the upper part of the display device 100, but the lower part, left part, and right part may have a similar structure. The glass lens 110 has a front surface 112 facing the front side and a rear surface 114 facing the rear side. A display panel 200 is attached to the center part of the rear surface 114 of the glass lens 110.
[0019] The display panel 200 includes an optical adhesive sheet 210, a liquid crystal panel 220, and a backlight unit 230. The liquid crystal panel 220 and the backlight unit 230 of the display panel 200 have a plate-like shape extending in the yz plane, and the liquid crystal panel 220 is disposed in front of the backlight unit 230. The liquid crystal panel 220 is also bonded to the rear surface 114 of the glass lens 110 via the optical adhesive sheet 210. The backlight unit 230 illuminates the liquid crystal panel 220, so that an image displayed on the liquid crystal panel 220 is emitted toward the glass lens 110 as display light. Therefore, the front surface of the liquid crystal panel 220 is also called a display surface 240. The display surface 240 has a rectangular shape in the yz plane. Side surfaces 260 are disposed in the xy plane and the zx plane of the backlight unit 230. For example, the display panel 200 includes four side surfaces 260.
[0020] The chassis 300 includes a rear plate 310 and a side wall 320, which are integrally formed. The rear plate 310 of the chassis 300 has a plate-like shape extending in the yz plane. The central portion of the rear plate 310 covers the backlight unit 230 from the rear side. The portion of the rear plate 310 that does not cover the rear side of the backlight unit 230 is a peripheral portion 312, and the peripheral portion 312 is provided with a side wall 320 extending toward the front side. The side wall 320 surrounds the side surface 260 of the display panel 200. The side wall 320 has an outer surface 322 and an inner surface 324. The inner surface 324 faces the side surface 260 of the display panel 200, and the outer surface 322 faces the opposite side to the inner surface 324. The combination of the rear plate 310 and the side wall 320 has a box shape with an open front side. The frontmost portion of the side wall 320 is a front end portion 330, which has a frame-like shape in the yz plane.
[0021] The front frame 120 is disposed between the front end 330 of the side wall 320 of the chassis 300 and the peripheral portion 116 of the rear surface 114 of the glass lens 110. The front frame 120 includes a front portion 180 and a rear portion 182, and the front portion 180 is located forward of the rear portion 182. The rear portion 182 is attached to the chassis 300 by gripping the side wall 320 from the front end 330 side. The portion of the rear portion 182 where the side wall 320 is gripped from the front end 330 side is the insertion groove 122. The structure of the front frame 120 and the chassis 300 is a chassis insert integrated structure. The chassis insert integrated structure is manufactured by insert molding the front frame 120 and the chassis 300. On the other hand, the mounting surface 124 is disposed in the front portion 180. As described above, since the front frame 120 is made of resin, the flatness of the mounting surface 124 can be made higher than the flatness of the chassis 300 .
[0022] A resin-made support member 400 is inserted between the front frame 120 and the glass lens 110. The support member 400 is integrally formed by a first portion 410 and a second portion 420. The first portion 410 has a frame shape in the yz plane, and is disposed between the mounting surface 124 of the front frame 120 and the rear surface 114 of the glass lens 110. The front surface of the first portion 410 is adhered to the rear surface 114 of the glass lens 110 by a first adhesive member 140. The rear surface of the first portion 410 is adhered to the second adhesive member 142 by a second adhesive member 142. The first adhesive member 140 and the second adhesive member 142 are, for example, double-sided tape. In addition, the second portion 420 is disposed from the inner portion of the first portion 410 toward the rear side. The second portion 420 supports the backlight unit 230. The support member 400 is used to bond the cover of the backlight unit 230 to the glass lens 110, but the support member 400 may be omitted depending on the shape of the backlight unit 230, etc. In this manner, the peripheral portion 116 of the rear surface 114 of the glass lens 110 is attached directly or indirectly to the attachment surface 124.
[0023] In order to narrow the frame, the thickness of the front frame 120 is reduced. In general, when the thickness of the front frame 120 is reduced, the front frame 120 becomes more likely to come off the chassis 300 due to an external force, and the strength is reduced. However, in this embodiment, since the chassis insert is integrated, even if the thickness of the front frame 120 is thin, the front frame 120 is less likely to come off the chassis 300 due to an external force, and the strength of the front frame 120 and the chassis 300 is ensured. This makes it possible to ensure strength and narrow the frame at the same time.
[0024] Below, modified structures for making it even more difficult for the front frame 120 to come off the chassis 300 even when an external force is applied will be described. Figures 4(a)-(f) show various structural examples of the front frame 120 and the chassis 300. Figure 4(a) is a perspective view of the combined structure of the front frame 120 and the chassis 300 as viewed from the front side. An area B is defined, and partial cross-sectional views along area B are shown as in Figures 4(b) to 4(f).
[0025] 4(b), a chamfering process is performed on a front end 330 of a side wall 320 of the chassis 300, thereby forming an inclined surface 332 between the front end 330 and an inner surface 324. At least a part of the insertion groove 122 of the rear portion 182 contacts the part of the front end 330 that has been chamfered, i.e., the inclined surface 332.
[0026] In FIG. 4(c), a through hole 326 penetrating between an outer surface 322 and an inner surface 324 is provided in a side wall 320 of the chassis 300. At least a part of the insertion groove 122 of the rear portion 182 is also located in the through hole 326 as a through hole filling portion 126. In FIG. 4(d), a protrusion 328 protruding outward from the outer surface 322 is provided in the side wall 320 of the chassis 300. The protrusion 328 is formed, for example, by half-punching. At least a part of the insertion groove 122 of the rear portion 182 covers the protrusion 328.
[0027] 4(e), a through hole 326 penetrating between an outer surface 322 and an inner surface 324 is provided in a side wall 320 of the chassis 300. A protrusion 328 protruding outward along an edge of the through hole 326 is provided in the outer surface 322 of the side wall 320. At least a part of the insertion groove 122 of the rear portion 182 is also disposed in the through hole 326 as a through hole filling portion 126, and covers the protrusion 328.
[0028] In Fig. 4(f), a claw portion 334 is provided by cutting and raising the side wall 320 of the chassis 300. The claw portion 334 extends toward the outside of the display panel 200 (not shown) and from the front side to the rear side. At least a part of the insertion groove 122 of the rear portion 182 covers the claw portion 334. Figs. 4(b)-(f) increase the contact area between the front frame 120 and the chassis 300, and also increase the adhesive force between the front frame 120 and the chassis 300.
[0029] 5(a)-(b) show various structural examples of the front frame 120 and the chassis 300. FIG. 5(a)-(b) are perspective views of the combined structure of the front frame 120 and the chassis 300 as viewed from below. In FIG. 5(a), a recess 336 extending from the front to the rear is provided in the front end 330 of the side wall 320 of the chassis 300. The recess 336 has a shape in which its width in the lateral direction increases with increasing distance from the front end 330. At least a portion of the rear portion 182 is also located in the recess 336 as an anchor 128.
[0030] 5(b) is different from FIG. 5(a) in the shape of the recess 336. The recess 336 has a stadium shape or a capsule shape. At least a portion of the rear portion 182 is located as the anchor 128 in the recess 336.
[0031] The conventional display device 100 is covered by a front frame 120 and a rear frame 130. The front frame 120 and the rear frame 130 may be integrally molded. FIG. 6 is a partial cross-sectional view showing an enlarged portion of a display device 100 according to a modified example. FIG. 6 is shown in the same manner as FIG. 3, and the glass lens 110, the display panel 200, the chassis 300, and the support member 400 are the same as those in FIG. 3. The integrated frame 170 is a member in which the front frame 120 and the rear frame 130 in FIG. 3 are integrated together, and is made of resin.
[0032] According to this embodiment, since the resin front frame has a mounting surface for mounting the peripheral portion of the rear surface of the glass lens, the flatness of the mounting surface can be increased even if the flatness of the chassis is low. Furthermore, since the flatness of the mounting surface is increased even if the flatness of the chassis is low, the display quality can be maintained even if the flatness of the chassis is low. Furthermore, since the rear portion of the front frame is attached to the chassis by being gripped from the front end of the side wall, the front frame is unlikely to come off the chassis even if an external force is applied. Furthermore, since the front frame is unlikely to come off the chassis even if an external force is applied, the strength of the display device can be ensured. Furthermore, since the strength of the display device is ensured while the frame of the display device is narrowed, the design freedom can be improved. Furthermore, since the glass lens is attached to the front frame with high flatness and the front frame and the chassis are integrated into a chassis insert structure, the frame can be narrowed while ensuring the quality of the display.
[0033] In addition, since a sheet metal chassis is used, versatility can be improved. In addition, the cost of using a sheet metal chassis can be reduced. In addition, since the chassis has an inclined surface, the contact area between the front frame and the chassis can be increased. In addition, since the contact area between the front frame and the chassis is increased, the adhesive strength between the front frame and the chassis can be improved. In addition, since the chassis is provided with a through hole, friction between the front frame and the chassis can be increased. In addition, since friction between the front frame and the chassis is increased, the adhesive strength between the front frame and the chassis can be improved.
[0034] In addition, since the chassis is provided with a protrusion, the friction between the front frame and the chassis can be increased. Furthermore, since the chassis has a claw portion, the friction between the front frame and the chassis can be increased. Furthermore, since the chassis is provided with a recess, the friction between the front frame and the chassis can be increased. Furthermore, since the front frame and the rear frame surround the chassis, the chassis can be protected. Furthermore, since the front frame and the rear frame are molded integrally, the number of parts can be reduced.
[0035] An overview of one aspect of the present disclosure is as follows. A display device according to one aspect of the present disclosure includes a glass lens having a front surface facing the front and a rear surface facing the rear, a display panel attached to a central portion of the rear surface, a chassis having a rear plate covering the display panel from the rear side and side walls extending from peripheral portions of the rear plate toward the front side while surrounding the side surfaces of the display panel, and a resin frame disposed between the front ends of the side walls and the peripheral portion of the rear surface. The frame includes a rear portion and a front portion located forward of the rear portion, the rear portion is attached to the chassis by gripping the side walls from the front end side, and the front portion has an attachment surface to which the peripheral portion of the rear surface is attached.
[0036] According to this embodiment, since the resin frame has a mounting surface for mounting the peripheral portion of the rear surface of the glass lens, the display quality can be maintained even if the flatness of the chassis is low.
[0037] The chassis may be a sheet metal chassis. In this case, the use of a sheet metal chassis can improve versatility.
[0038] The front end portion may have an inclined surface, and at least a part of the rear portion may be in contact with the inclined surface. In this case, since the chassis has an inclined surface, the adhesive strength between the frame and the chassis can be improved.
[0039] The side wall may have a through hole penetrating the side wall, and at least a part of the rear portion may be located within the through hole. In this case, since the chassis has a through hole, it is possible to improve the adhesive strength between the frame and the chassis.
[0040] The side walls may have protrusions, and the rear portion may cover the protrusions. In this case, the chassis is provided with protrusions, so that the adhesive strength between the frame and the chassis can be improved.
[0041] The side wall may have a claw portion extending from the front side to the rear side toward the outside of the display panel, and the rear portion may cover the claw portion. In this case, since the chassis has the claw portion, the adhesive strength between the frame and the chassis can be improved.
[0042] The front end portion may have a recess extending from the front side to the rear side, and at least a portion of the rear portion may be located within the recess. In this case, since the recess is provided in the chassis, the adhesive strength between the frame and the chassis can be improved.
[0043] The frame may be a front frame, and the display device may further include a rear frame that covers the chassis from the rear side. In this case, the front frame and the rear frame surround the chassis, so that the chassis can be protected.
