[0006] The problem to be solved by utility models

[0007] According to the aforementioned prior art, the allowable gap between the locked portion of the front frame and the locked portion of the rear frame can be increased, thereby enabling more reliable integration of the front and rear frames. On the other hand, aesthetics are also an important factor for the outer frame. Therefore, although not described in the aforementioned prior art, the outer frame sometimes employs a delicate structure for aesthetic reasons. However, when such a delicate structure is used, the outer frame may break upon impact, causing fragments to scatter.

[0008] One object of this invention is to provide a display device having an aesthetically pleasing outer frame with an elegant structure, while ensuring the safety of conventional display devices.

[0009] Methods for solving problems

[0010] To achieve the above objectives, a representative display device of the present invention displays an image on a front surface, comprising: a display panel; a structure surrounding the periphery of the display panel; an edge portion, which is an integrally formed member with a cross-section bent on the front surface side of the display device and attached to the periphery of the structure; and an elastic body disposed inside the bent portion of the edge portion and bonded to the structure and the edge portion.

[0011] Effects of the utility model

[0022] Next, the embodiments of the present invention will be described with reference to the accompanying drawings.

[0023] Implementation Plan 1

[0024] Figure 1 This is an external structural diagram of the display device according to implementation scheme 1.

[0025] Display device 10 is an in-vehicle display device installed in a vehicle.

[0026] The display device 10 includes a rear surface cover 20, a structure 30, and a display panel 40.

[0027] The display panel 40 is a lens assembly that includes a liquid crystal panel and a cover lens. The display output side of the display panel 40 is referred to as the display surface, and the other surface is referred to as the rear surface.

[0028] Structure 30 forms the outer frame surrounding the display panel.

[0029] The rear surface cover portion 20 is fixed to the structure 30 and covers the rear surface of the display panel 40 and the structure 30. In the display device 10, for convenience, the display output side of the display panel 40 is referred to as the front surface.

[0030] Figure 2 (a) and Figure 2 (b) is a reference example of the construction of the display device. The display panel 40 is a lens assembly with the following construction: a cover lens 41 is bonded to a liquid crystal display (LCD) 43 by a transparent adhesive (OCR: optically transparent resin) 42.

[0031] The display panel 40 is adhered to the structure 30a by a room temperature vulcanizing (RTV) silicone rubber adhesive 50.

[0032] Structure 30a is fixed to the rear surface cover portion 20, for example, by engaging with a protrusion. It should be noted that the shape of structure 30a differs from that of structure 30 in embodiment 1, and therefore different reference numerals are used.

[0033] exist Figure 2 (a) and Figure 2 In the reference example (b), the outer periphery of the structure 30a directly forms the outer frame of the display panel 40, i.e., the outer edge of the display device 10. The outer frame is easily seen by the user and greatly affects the aesthetic appearance of the display device 10. When the structure 30a is manufactured using resin or the like, the inner side of the edge portion is made hollow to avoid shrinkage marks and to form the desired high-precision shape.

[0034] The outer edge of the display device 10 protrudes beyond the display surface of the display panel 40 by a predetermined amount to protect the display panel 40.

[0035] In other words, when an object impacts the display device 10, it will strike the edge of the outer frame before hitting the display panel 40. However, if the inside of the edge is hollow, the edge will break upon impact with the outer frame, causing fragments to scatter.

[0036] Figure 3This is an illustration of the damage caused to the reference example. Figure 3 The image shows the state of object 60 impacting the outer frame, simulating the occurrence of an accident.

[0037] At this point, the impact point between the outer frame of structure 30a and object 60 breaks, and fragments scatter (C1). Furthermore, the boundary between structure 30a and rear surface cover 20 is damaged, causing fragments to scatter (C2). Additionally, the edge portion cracks midway, creating a large step (C3).

[0038] Figure 4 (a) and Figure 4 (b) is a structural diagram of the display device according to embodiment 1. In the display device 10 of embodiment 1, the structure 30 has an edge portion 31 attached to the periphery. In other words, the outer edge of the display device 10, which also serves as the outer frame of the display panel 40, is not formed by the outer periphery of the structure 30a itself as in the reference example, but is formed by a separate component.

[0039] The edge portion 31 is an integrally molded component with a curved cross-section, making the front surface of the display device 10 convex.

[0040] The edge portion 31 is bonded to the structure 30 by an elastic body 32 that fills the curved inner side of the edge portion 31.

[0041] The edge portion 31 protrudes from the display surface of the display panel 40 by a predetermined amount and protects the display panel 40.

[0042] As in the example, the display panel 40 is composed of a lens assembly in which a cover lens 41 is bonded to a liquid crystal display 43 using a transparent adhesive 42.

[0043] The display panel 40 is adhered to the structure 30 by RTV silicone rubber adhesive 50.

[0044] The structure 30 is fixed to the rear surface cover portion 20, for example, by engaging with the protrusion.

[0045] The structure 30 has a protrusion on its outer periphery, and the edge portion 31 is attached to the structure 30 by abutting the protrusion with the elastic body 32 exposed on the inner periphery side.

[0046] In other words, the display surface side of the outer edge of the structure 30 serves as the adhesive allowance for adhering the edge portion 31 to the elastic body 32.

[0047] The depth of the inner peripheral side of the edge portion 31 is less than the depth of the outer peripheral side of the edge portion 31.

[0048] Furthermore, since the gap 33 is provided along the entire circumference between the inner peripheral end of the edge portion 31 and the structure 30, the inner peripheral end of the edge portion 31 does not directly contact the structure.

[0049] Furthermore, the outer peripheral end portion of the edge portion 31 and the rear surface cover portion 20 form the side surface of the display device 10, and the gap 33 is provided along the entire circumference between the outer peripheral end portion of the edge portion 31 and the rear surface cover portion 20, so that the outer peripheral end portion of the edge portion 31 does not directly contact the rear surface cover portion 20.

[0050] Figure 5 This is an illustration of the damage caused by implementation scheme 1. Figure 5 This illustrates the state in which object 60 impacts edge 31. For example, when a vehicle equipped with display device 10 is involved in an accident, it is conceivable that a passenger's head, arm, etc., might impact display device 10. In this case, object 60 is part of the human body.

[0051] exist Figure 5 In the event of impact, the impact point between the edge portion 31 and the object 60 is damaged (C1). However, the inner side of the edge portion 31 is filled with and adheres to the elastic body 32, so even if the edge portion breaks into fragments, the edge portion will remain adhered to the elastic body 32 and will not scatter.

[0052] Furthermore, gaps 33 are provided between the edge portion 31 and the rear surface cover portion 20, and between the edge portion 31 and the structure 30. The gaps 33 and the elastic body 32 absorb impact. This prevents breakage (C2) at the end of the edge portion 31 and prevents cracks (C3) from forming along the middle of the edge portion 31. Even if a crack forms in the middle of the edge portion 31, the elastic body 32 fills the inner side, preventing large steps from forming. Therefore, even if the object 60 is a human body, injury caused by flying debris or breakage can be prevented.

[0053] The material of the elastic body 32 is preferably RTV (room temperature vulcanizing) silicone rubber.

[0054] If the elastic body 32 is made of the same material as the adhesive 50 used to bond the display panel 40 and the structure 30, the same equipment can be used to fill the elastic body 32 and apply the adhesive 50. Alternatively, filling the elastic body 32 and applying the adhesive 50 can be performed simultaneously in the same process.

[0055] Furthermore, by forming the structure 30 and the edge portion 31 as separate components, the edge portion 31 can be easily plated.

[0056] Figure 6 (a) Figure 6 (b) and Figure 6 (c) is an explanatory diagram of structure 30 and edge portion 31. Structure 30 has a protrusion that engages with rear surface cover portion 20. The plating location becomes hard and brittle, so if the edge is part of structure 30a as in the reference example, the protrusion must be protected from plating. To protect the protrusion from plating, it is necessary to mask the protrusion to prevent plating from adhering to it, or to perform two-color molding on the protrusion and the portion to be plating, but this results in an increase in the number of processes and increased costs.

[0057] On the other hand, in the display device 10 of embodiment 1, the edge portion 31 to be plated is a separate component. Therefore, the entire edge portion 31 can be plated and then bonded to the structure 30 by the elastic body 32.

[0058] Figure 7 (a) Figure 7 (b) and Figure 7 (c) is an explanatory diagram of the positioning component.

[0059] like Figure 7 (a) Figure 7 (b) and Figure 7 As shown in (c), the structure 30 includes a thin plate member 34 and a thin plate member 35.

[0060] The outer edge of the structure 30 has a step in a surface parallel to the display surface, and the surface facing the inner peripheral end of the edge 31 is further away from the display panel 40 than the surface to which the display panel 40 is attached.

[0061] The thin plate member 34 stands upright from the surface facing the inner peripheral end of the edge portion 31 in a direction perpendicular to the display surface. Furthermore, the step of the structure 30 and the thin plate member 34 clamp the inner peripheral end of the edge portion 31, thereby defining the positional relationship between the edge portion 31 and the structure 30 in a direction parallel to the display surface.

[0062] The thin plate member 35 stands outward from the surface of the structure 30 corresponding to the side surface of the display device 10 and abuts against the outer peripheral side of the edge portion 31, thereby determining the positional relationship between the edge portion 31 and the structure 30 in a direction parallel to the display surface.

[0063] Although not shown in the accompanying drawings, a thin plate member may be provided that rises from the structure 30 toward the inner peripheral end portion of the edge portion 31 and abuts against the inner peripheral end portion 31, thereby determining the positional relationship between the edge portion 31 and the structure 30 in a direction perpendicular to the display surface.

[0064] The thicknesses of the sheet metal members 34 and 35 are set such that these members break upon impact with the edge portion 31, and serve as cushioning members to mitigate the impact. This also applies to the sheet metal members that define the positional relationship between the edge portion 31 and the structure 30 in a direction perpendicular to the display surface.

[0065] The thin-plate component can position the edge 31 and the structure 30 and provide impact absorption.

[0066] As described above, the display device 10 disclosed in this utility model includes:

[0067] Display panel 40; structure 30 surrounding the periphery of display panel 40; edge portion 31, which is an integrally molded member with a cross-section curved on the front surface side of display device 10 and attached to the periphery of structure 30; and

[0068] An elastic body 32 is disposed on the inside of the curved portion of the edge portion 31 and is bonded to the structure 30 and the edge portion 31.

[0069] Therefore, even if the edge 31 is damaged, it can prevent fragments from scattering and large cracks from forming in the steps.

[0070] Furthermore, the depth of the inner peripheral side of the edge portion 31 is less than the depth of the outer peripheral side of the edge portion 31.

[0071] Furthermore, the gap is provided around the entire circumference between the inner peripheral end of the edge portion 31 and the structure 30, so that the inner peripheral end of the edge portion does not directly contact the structure.

[0072] In addition, a rear surface cover plate 20 is also provided, which is fixed to the structure 30 and covers the display panel 40 and the structure 30.

[0073] The outer peripheral end portion of the edge portion 31 and the rear surface cover portion 20 constitute the side surface of the display device 10; and the gap is provided along the entire circumference between the outer peripheral end portion of the edge portion 31 and the rear surface cover portion 20; and the outer peripheral end portion of the edge portion 31 is not directly connected to the rear surface cover portion 20.

[0074] Therefore, the impact is absorbed by the gap and the elastic body 32.

[0075] In addition, the depth of the inner peripheral side of the edge portion 31 is less than the depth of the outer peripheral side of the edge portion 31, and the outer peripheral end portion of the edge portion 31 and the rear surface cover portion 20 form the side surface of the display device 10. Therefore, the structure 30 does not expose the side surface, and the design of the side surface can be flexibly determined.

[0076] In addition, thin plate members are set on the structure 30, defining the positional relationship between the structure and the edge, and breaking when the edge is impacted to mitigate the impact.

[0077] Therefore, the edge 31 can be positioned and impact absorption can be achieved.

[0078] Furthermore, the structure 30 has a protrusion on its outer periphery, and the edge portion 31 is attached to the structure 30 by making the elastic body 32 exposed on the inner periphery side adjacent to the protrusion.

[0079] Therefore, the outer periphery of the structure 30 serves as the adhesive allowance for the elastic body 32.

[0080] In addition, the edge portion 31 can also be plated.

[0081] Since the edge portion 31 and the structure 30 are separate parts, the edge portion 31 can be plated and then bonded to the structure 30 without affecting the structure 30. This allows for greater freedom in designing the edge portion 31 at a low cost.

[0082] Furthermore, the elastic body 32 is room temperature vulcanized (RTV) silicone rubber, and the edge portion 31 and the structure 30 are preferably bonded together by RTV silicone rubber.

[0083] In addition, the elastic body 32 may also be made of the same material as the adhesive 50 that bonds the display panel 40 and the structure 30.

[0084] This type of construction facilitates equipment sharing and reduces processes.

[0085] The display device 10 can be an in-vehicle display device installed in a vehicle. For in-vehicle display devices, it is especially important to prevent structural components from being damaged or scattered in the event of an accident.

[0086] It should be noted that this utility model is not limited to the above examples, but includes various modified examples. For example, although the above examples have been described in detail for the purpose of describing this utility model in an easily understandable manner, this utility model is not necessarily limited to examples having all of the above configurations. Furthermore, not only can such configurations be deleted, but configurations can also be replaced or added.
