[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-12969 Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of the display device described in Patent Document 1, dimensional tolerances during molding of the frame portion (garnish) and the protective plate may result in a small clearance between the frame portion and the edge of the protective plate.In this case, it is possible that water or other moisture may enter the inside of the display device through the clearance, which may reduce the waterproofing properties. The present disclosure has been made in view of the above circumstances, and has an object to provide a display device that can improve waterproofness. [Means for solving the problem]

[0005] In order to achieve the above object, the display device according to the present disclosure comprises: a display unit for displaying an image; a protective plate that covers the display unit from the front and has a transparent portion through which light representing the image passes and an outer edge portion located outside the transparent portion; a housing having a side wall portion located behind the outer edge portion and accommodating a display unit inside the side wall portion; a garnish having a supported portion facing a back surface of the outer edge portion and supported by the side wall portion, and an upright wall portion facing an end surface of the protection plate and standing relative to the supported portion; an elastic member positioned between the supported portion and the display portion, [Effects of the Invention]

[0006] According to the present disclosure, the intended purpose can be achieved and waterproofness can be improved. [Brief explanation of the drawings]

[0007] [Figure 1] FIG. 1 is a front view of a display device according to an embodiment of the present disclosure. [Figure 2] FIG. 2 is a schematic cross-sectional view of the display device according to the embodiment taken along line AA in FIG. 1. [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of the present disclosure will be described with reference to the drawings.

[0009] 1 to 3, the display device 100 according to this embodiment includes a display unit 1, a protective plate 2, a housing 3, a garnish 4, and an elastic body (elastic member) 5. For example, the display device 100 is installed on the dashboard (instrument panel) of a vehicle.

[0010] Hereinafter, as directions relative to the display device 100, the direction in which the display unit 1 displays an image as described below will be referred to as the "front" (shown as "F" in FIG. 2), and the opposite direction will be referred to as the "rear" (shown as "B" in FIG. 2). The rear surface of a predetermined configuration provided on the display device 100 will also be referred to as the "rear face."

[0011] The display unit 1 includes a display such as an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display, and a frame that houses the display. The display unit 1 has a display surface 11 that displays an image on the front surface of the display. The display unit 1 is capable of displaying images showing various types of information related to the vehicle under the control of a control unit (not shown).

[0012] The protective plate 2 is configured to cover the display unit 1 from the front, and is configured by forming a light-shielding layer by printing or the like on a transparent plate made of organic glass or inorganic glass. The transparent plate is approximately rectangular when viewed from the front. For example, the light-shielding layer is formed on the back surface of the transparent plate. The transparent plate of this embodiment is flat, and the display device 100 is configured as a flat display type device. For example, the protective plate 2 is fixed to the front surface of the display unit 1 by optical bonding, and a transparent elastic resin 6 is filled between the protective plate 2 and the display unit 1 as a bonding member. In other words, in this case, the display unit 1 is configured to be fixed to the protective plate 2 by the transparent elastic resin 6.

[0013] The protective plate 2 has a transmissive portion 20 through which light representing an image displayed on the display surface 11 passes, and an enclosing portion 21 that surrounds the transmissive portion 20. The transmissive portion 20 is a portion of the aforementioned transparent plate where no light-shielding layer is formed. The enclosing portion 21 is a portion of the aforementioned transparent plate where a light-shielding layer is formed. The enclosing portion 21 is located on the outer edge of the protective plate 2, and has an outer edge portion 21a that faces a side wall portion 31 (described below) in the front-to-rear direction. In other words, the outer edge portion 21a is located outside the transmissive portion 20.

[0014] As shown in FIG. 2, the housing 3 is configured to house the display unit 1 and has a bottom 30 and a side wall 31 that stands forward from the outer edge of the bottom 30. The housing 3 is formed in a box shape with an opening surrounded by the front end of the side wall 31. The side wall 31 is located behind the outer edge 21a of the protection plate 2. The housing 3 houses the display unit 1 in a chamber surrounded by the side wall 31 and the bottom 30. In other words, the housing 3 houses the display unit 1 inside the side wall 31. The frame of the display unit 1 is fixed to the bottom 30 with screws S, for example.

[0015] The garnish 4 is a frame-shaped component formed around the edge of the protective plate 2, and is made of, for example, synthetic resin. The garnish 4 may also be made of metal. As shown in Figures 1 and 3, the garnish 4 is formed in an end-frame shape. Here, end-frame shape means that a portion of the garnish 4 is cut out, creating an end on the garnish 4 that runs along the outer periphery of the protective plate 2, and thus the garnish 4 does not completely surround the periphery of the protective plate 2. In other words, due to the presence of the cutout portion, the garnish 4 does not run along part of all of the edge surfaces of the protective plate 2. In the garnish 4 of this embodiment, a portion corresponding to one side of the protective plate 2, which is approximately rectangular when viewed from the front (the lower side extending in the left-right direction in Figure 1), is cut out.

[0016] The garnish 4 has a supported portion 41 that faces the back surface of the outer edge portion 21a and is supported by the side wall portion 31, and an upright wall portion 42 that faces the end face of the protective plate 2 and stands against the supported portion 41. As a result, the cross section of the garnish 4 has an L-shape, as shown in Fig. 2. Although not shown, the garnish 4 is engaged with the side wall portion 31 of the housing 3 by engaging means such as a hook mechanism.

[0017] As described above, with the garnish 4 having an end frame shape, even if the protective plate 2 and the garnish 4 interfere with each other, the garnish 4 can easily flex and deform, releasing stress and preventing damage to the protective plate 2 and the garnish 4. Furthermore, because the garnish 4 can flex and deform even if dimensional errors and thermal expansion or thermal contraction occur, the gap that occurs between the protective plate 2 and the garnish 4 can be reduced compared to conventional configurations in which the protective plate 2 is supported by the housing. Furthermore, the configuration of the display device 100 is simple because it is only necessary to make the garnish 4 and the housing 3 separate components.

[0018] For example, the display device 100 is provided so as to protrude from an opening formed in the dashboard of a vehicle. The imaginary line V shown in Fig. 1 indicates an example of the boundary between the part exposed from the dashboard and the part hidden within the dashboard. Therefore, the cutout part of the garnish 4 is usually not visible to the user of the display device 100, and the aesthetic appearance of the display device 100 is maintained.

[0019] As shown in Fig. 2, the elastic body 5 has a substantially rectangular cross section and is stretchably positioned (interposed) between the supported portion 41 of the garnish 4 and the display unit 1. The elastic body 5 is a sealing material made of, for example, a foam or elastomer, which prevents moisture such as water from entering the housing 3 through the gap between the protective plate 2 and the garnish 4 (the gap between the display unit 1 and the garnish 4), thereby improving waterproofing. For example, in Fig. 2, the left side surface of the elastic body 5 is fixed to the inner surface of the supported portion 41 with double-sided tape (not shown), and the right side surface of the elastic body 5 is fixed to the display unit 1 with double-sided tape (not shown). Although not shown, the elastic body 5 is formed in the shape of a rectangular frame when viewed from the front. Also, although not shown, in the display device 100, in the portion corresponding to the notch formed in the garnish 4 (the portion corresponding to one side of the protective plate 2 (the lower side extending in the left-right direction in Figure 1)), the outer edge portion 21a (enclosing portion 21) of the elastic body 5 is supported by the side wall portion 31 of the housing 3.

[0020] The present invention is not limited to the above-described embodiments, modifications, and drawings. Modifications (including the omission of components) can be made as appropriate within the scope of the present invention.

[0021] Although the above example shows the protective plate 2 in a flat plate shape, the protective plate 2 may be a curved plate shape (including a plate shape having a curved surface in part) or a curved plate shape. Furthermore, the protective plate 2 is not limited to a rectangular shape when viewed from the front, but may also be a polygonal shape. Where in the garnish 4 the notch is formed to form a frame shape with ends can also be determined arbitrarily depending on the conditions.

[0022] In the above description, in order to facilitate understanding of the present disclosure, descriptions of well-known technical matters have been omitted as appropriate.

[0023] This invention allows various embodiments and modifications without departing from the broad spirit and scope of this invention. Furthermore, the above-described embodiments are intended to explain this invention and do not limit the scope of this invention. That is, the scope of this invention is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and the meaning of the invention equivalent thereto are considered to be within the scope of this invention. [Explanation of symbols]
