Summary of the Invention

Problems to be Solved by the Invention

[0004] In the device described in Patent Document 1, since it is necessary to provide an elastic body on the end face of the protective plate, there is a risk that the configuration becomes complicated. On the other hand, if the gap between the end face of the protective plate and the garnish as a part of the housing is forcibly narrowed while simply omitting the elastic body, it may become difficult to assemble the protective plate to the housing due to dimensional errors and the influence of thermal expansion or contraction.

[0005] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a display device having a simple configuration and capable of suppressing a gap generated between a protective plate and a garnish.

Means for Solving the Problems

[0006] To achieve the above object, a display device according to the present disclosure includes: a display unit that displays an image; a transmissive portion through which light representing the image passes, and a protective plate having an outer edge portion located outside the transmissive portion and covering the display unit from the front; a housing having a side wall portion located behind the outer edge portion and accommodating the display unit inside the side wall portion; a garnish that faces the back surface of the outer edge portion and is supported by the side wall portion, and that has a standing wall portion that faces the end surface of the protective plate and stands against the supported portion; The garnish has an end frame shape and does not extend along some of all the end surfaces of the protective plate.

Advantages of the Invention

[0007] According to the present disclosure, a gap generated between the protective plate and the garnish can be suppressed with a simple configuration.

Modes for Carrying Out the Invention

[0009] An embodiment of the present disclosure will be described with reference to the drawings.

[0010] As shown in FIGS. 1 to 3, the display device 100 according to the present embodiment includes a display unit 1, a protection plate 2, a housing 3, a garnish 4, and an elastic body 5. For example, the display device 100 is installed on a dashboard (instrument panel) of a vehicle.

[0011] Hereinafter, as a direction with respect to the display device 100, the direction in which the display unit 1 displays an image as described later is defined as "front" (indicated as "F" in FIG. 2), and the opposite direction is defined as "rear" (indicated as "B" in FIG. 2). In addition, the rear surface of a predetermined configuration included in the display device 100 is also referred to as the "rear surface".

[0012] The display unit 1 includes a display composed of an LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence) display, or the like, 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 can display an image indicating various information related to the vehicle under the control of a control unit (not shown).

[0013] The protection plate 2 is configured to cover the display unit 1 from the front, and is formed by forming a light-shielding layer on a transparent plate made of organic glass or inorganic glass by printing or the like. The transparent plate has a substantially rectangular shape when viewed from the front. For example, the light-shielding layer is formed on the rear surface of the transparent plate. The transparent plate of the present embodiment is flat, and the display device 100 is configured as a flat display type device. For example, the protection plate 2 is fixed to the front surface of the display unit 1 by optical bonding, and a transparent elastic resin (not shown) is filled between the protection plate 2 and the display unit 1.

[0014] The protection plate 2 has a transmission portion 20 through which light representing an image displayed on the display surface 11 passes, and a surrounding portion 21 that surrounds the transmission portion 20. The transmission portion 20 is a portion of the aforementioned transparent plate where the light-shielding layer is not formed. The surrounding portion 21 is a portion of the aforementioned transparent plate where the light-shielding layer is formed. The surrounding portion 21 is located at the outer edge of the protection plate 2 and has an outer edge portion 21a that faces the side wall portion 31 described later in the front-rear direction. That is, the outer edge portion 21a is located outside the transmission portion 20.

[0015] As shown in FIG. 2, the housing 3 is configured to accommodate the display unit 1, and has a bottom portion 30 and a side wall portion 31 that stands forward from the outer edge of the bottom portion 30. The housing 3 is formed in a box shape with an opening in a portion surrounded by the front end of the side wall portion 31. The side wall portion 31 is located behind the outer edge portion 21a of the protection plate 2. The housing 3 accommodates the display unit 1 in a chamber surrounded by the side wall portion 31 and the bottom portion 30. That is, the housing 3 accommodates the display unit 1 inside the side wall portion 31. The frame of the display unit 1 is fixed to the bottom portion 30 by, for example, screws S.

[0016] The garnish 4 is a member formed in a frame shape around the end face of the protection plate 2 and is formed of, for example, a synthetic resin. Note that the garnish 4 may be formed of metal. The garnish 4 is formed in an end-framed shape as shown in FIGS. 1 and 3. Here, the end-framed shape means a shape in which a part of the garnish 4 is cut out, resulting in an end on the garnish 4 along the outer periphery of the protection plate 2 and not completely surrounding the periphery of the protection plate 2. That is, the garnish 4 does not extend along a part of all the end faces of the protection plate 2 due to the cutout portion. The garnish 4 of the present embodiment has a portion corresponding to one side (the lower side extending in the left-right direction in FIG. 1) of the protection plate 2 having a substantially rectangular shape when viewed from the front being cut out.

[0017] 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 a standing wall portion 42 that faces the end face of the protection plate 2 and stands with respect to the supported portion 41. The supported portion 41 has a surface portion 41a facing the elastic body 5 side and a back surface portion 41b facing the side wall portion 31 side. Thereby, as shown in FIG. 2, the cross-sectional shape of the garnish 4 is L-shaped. Although not shown, the garnish 4 is locked to the side wall portion 31 of the housing 3 by a locking means such as a hook mechanism.

[0018] As described above, according to the garnish 4 in the shape of a framed structure, even if the protective plate 2 and the garnish 4 interfere with each other, the garnish 4 can be easily bent and deformed, and by releasing the stress, breakage of the protective plate 2 and the garnish 4 can be prevented. Further, even if dimensional errors, thermal expansion or thermal contraction occur, since the garnish 4 can be bent and deformed, a gap generated between the protective plate 2 and the garnish 4 can be suppressed as compared with a configuration in which the protective plate 2 is supported by the housing as in the prior art. Further, since it is only necessary to make the garnish 4 and the housing 3 separate members, the configuration of the display device 100 is simple.

[0019] For example, the display device 100 is provided so as to project and stand out from an opening formed in the dashboard of the vehicle. The virtual line V shown in FIG. 1 shows an example of a boundary line between a portion exposed from the dashboard and a portion hidden inside the dashboard. Therefore, the cutout portion 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.

[0020] As shown in FIG. 2, the elastic body 5 has a substantially rectangular cross section and is located between the back surface of the outer edge portion 21a of the protective plate 2 and the supported portion 41 of the garnish 4. The elastic body 5 is, for example, a sealing material made of an elastomer, and thereby, it is possible to prevent water, dust, etc. from entering the inside of the housing 3 from the gap between the protective plate 2 and the garnish 4. For example, the front surface of the elastic body 5 is fixed to the back surface of the outer edge portion 21a with a double-sided tape (not shown), and the back surface of the elastic body 5 is fixed to the front surface of the supported portion 41 with a double-sided tape (not shown). Although not shown, the elastic body 5 is formed in a rectangular frame shape when viewed from the front. Further, although not shown, in the display device 100, in a portion corresponding to the cutout formed in the garnish 4 (a portion corresponding to one side of the protective plate 2 (the lower side extending in the left-right direction in FIG. 1)), the elastic body 5 is located between the protective plate 2 and the side wall portion 31 of the housing 3 and is fixed to both of them.

[0021] The present invention is not limited to the above-described embodiments, modifications, and drawings. It is possible to appropriately make changes (including deletion of components) without changing the gist of the present invention.

[0022] In the above description, an example where the protective plate 2 is flat has been shown. However, the protective plate 2 may be curved (including a plate shape having a curved surface in part) or may be a curved plate shape. Further, the protective plate 2 is not limited to a rectangular shape in a front view and may be a polygonal shape. And where to form a notch in the garnish 4 to make it an open-ended frame shape is also arbitrary according to conditions.

[0023] Furthermore, as shown in FIGS. 4 and 5, the supported portion 41 (surface portion 41a) may be provided with a protrusion X that supports the elastic body 5. In this case, in the surface portion 41a, an air layer Y is formed between the portion excluding the protrusion X and the elastic body 5. By configuring in this way, since only a part of the surface portion 41a, rather than the whole thereof, comes into contact with the elastic body 5, there is an advantage that the elastic body 5 is partially compressed and the compressive stress acting on the elastic body 5 is reduced. In the above description, the protrusion X is provided on the surface portion 41a. However, instead of this, for example, a protrusion having the same shape and function as the above protrusion X may be provided on the back surface of the outer edge portion 21a. Also, in some cases, instead of forming the protrusion X on the surface portion 41a and the outer edge portion 21a, protrusions having the same shape and function as the above protrusion X may be provided on the surface portion of the elastic body 5 and the back surface portion of the elastic body 5, respectively.

[0024] In the above description, for the purpose of facilitating the understanding of the present disclosure, the description of known technical matters has been appropriately omitted.

[0025] This invention can be implemented in various embodiments and modifications without departing from the broad spirit and scope of this invention. Also, the above-described embodiments are for explaining this invention and do not limit the scope of this invention. That is, the scope of this invention is indicated not by the embodiments but by the claims. And various modifications made within the scope of the claims and within the scope of the meaning of the invention equivalent thereto are regarded as being within the scope of this invention.
