Abstract
Description
Technical Field
[0001] The present disclosure relates to a video display device, and more particularly to a video display device capable of projecting a video onto a projection surface of a projector unit.
Background Art
[0002] Conventionally, a video display device has been proposed that deploys a screen installed on the ceiling portion of a vehicle or the like and projects a video or the like onto the screen (see, for example, Patent Document 1). In the video display device shown in Patent Document 1, a flexible flat display is housed in the ceiling portion of the vehicle, and when in use, the flat display is pulled out (deployed) in front of the rear seat to install the screen, and when not in use, the flat display is returned to the ceiling portion to store the screen in the ceiling. By installing such a video display device in a vehicle, a user sitting in the rear seat can enjoy a video on a large screen while the vehicle is in motion.

Summary of the Invention
Problems to be Solved by the Invention
[0004] However, when the screen is deployed in a general video display device, a large screen enters the user's field of view, so the projection surface of the screen becomes prominently recognized. For this reason, the unity with the interior (interior) of the vehicle cabin may be significantly impaired by the projection surface of the screen, or the atmosphere of the entire interior (interior) may be significantly damaged.
[0005] Furthermore, in typical video display systems, the screen is installed on the ceiling. When the screen is retracted into the ceiling, the outer surface of the video display system (such as the back of the screen) is exposed on the ceiling. This exposed outer surface could potentially detract from the overall uniformity of the vehicle's interior and significantly worsen the overall atmosphere of the interior.
[0006] The video display device disclosed herein was made in view of the circumstances described above, and aims to provide a video display device that does not impair the sense of unity with interior furnishings. [Means for solving the problem]
[0007] To solve the above problems, the video display device of this disclosure comprises a screen unit installed inside a vehicle and a video projection unit that projects an image onto the screen unit. The color tone of the projection surface of the screen unit onto which the image is projected is a color tone common to the color tone of the interior furnishings inside the vehicle surrounding the screen. [Effects of the Invention]
[0008] According to the video display device described herein, the video display device does not impair the sense of unity among interior furnishings. [Brief explanation of the drawing]
[0009] [Figure 1] This figure shows a schematic configuration of a video display device according to an embodiment. [Figure 2] This is a side cross-sectional view showing the structure of the screen portion according to the embodiment. [Figure 3] This is a side cross-sectional view showing the structure of another screen section according to the embodiment. [Modes for carrying out the invention]
[0010] An example of the video display device described herein will be shown and described in detail with reference to the drawings. Figure 1 is a diagram showing the schematic configuration of the video display device. The video display device 1 has a screen section 100 and a projector section (video projection section) 200. The screen section 100 is located between the rear seats S2 and the front seats S1 (driver's seat and passenger seat) of the vehicle 300 and is installed on the ceiling section 310 of the vehicle 300. The projector section 200 is located further back than the screen section 100 and is installed on the ceiling section 310 of the vehicle 300. For convenience of explanation, Figure 1 and Figures 2 and 3, which will be described later, are shown with "Fr." indicating the front of the vehicle, "Re." indicating the rear of the vehicle, "To." indicating above the vehicle, and "Bo." indicating below the vehicle, along with arrows indicating their directions.
[0011] The screen section 100 has a flat plate shape and is mounted on the ceiling section 310 of the vehicle 300 so as to be deployable and retractable, with its upper end as a pivot axis. When the screen section 100 is deployed, a projection surface 115 is formed on the plane on the rear (Re.) side of the vehicle (the side where the projector section 200 is installed). When the screen section 100 is deployed, the projection surface 115 is in an upright position and is positioned to face the user seated in the rear seat S2.
[0012] When the screen section 100 is retracted, as shown in Figure 1, the upper end of the screen section 100 rotates so that the projection surface 115 moves toward the ceiling surface, and the back surface of the screen section 100 (the plane opposite to the projection surface 115) becomes one with (parallel to) the ceiling surface. The back surface of the screen section 100 is referred to as the outer surface 117.
[0013] The projector unit 200, installed on the rear (Re.) side of the ceiling section 310, projects an image onto the upright projection surface 115. The projector unit 200 uses a laser light source. By using a laser light source, it is possible to project high-brightness light (image) onto the projection surface 115. Therefore, even in bright environments such as the interior of a vehicle during the daytime, a highly visible image can be projected onto the projection surface 115.
[0014] Figure 2 is a lateral cross-sectional view showing the structure of the screen section 100. The screen section 100 is composed of a base material layer 110 and a surface layer 120. The base material layer 110 has a flat plate shape, and the surface layer 120 is laminated on both sides of the base material layer 110 (the plane on the front (Fr.) side of the vehicle and the plane on the rear (Re.) side of the vehicle). The surface layer 120 laminated on the rear (Re.) side of the base material layer 110 forms the projection surface 115. In addition, the surface layer 120 laminated on the front (Fr.) side of the base material layer 110 forms the outer surface 117.
[0015] The surface layer 120 has a color tone that is consistent with the interior components of the vehicle, more specifically, with the color tone of the interior ceiling, doors, or seats. A consistent color tone means that, when a user views the surface layer 120, based on the user's visual perception (visual sensitivity, etc.), the surface layer 120 does not appear out of place (looks identical) to the color of the surrounding interior components. For example, this would include cases where neighboring colors are used on the color wheel, or where the surface patterns or designs are consistent.
[0016] In this embodiment, the same material as the interior components (for example, chairs and doors located around the projection surface 115) is used for the surface layer 120 that constitutes the projection surface 115. Therefore, when the unfolded projection surface 115 is viewed by the user, the user will not be aware of the difference in color tone between the interior components and the surface layer 120, and will be able to view the projection surface 115 as identical to the interior components without any sense of incongruity. Thus, the projection surface 115 (surface layer 120, screen portion 100) does not impair the sense of unity of the interior (interior components) or the overall atmosphere of the vehicle.
[0017] Furthermore, in this embodiment, the same material as the interior components (e.g., the ceiling) is used for the surface layer 120 that constitutes the outer surface 117. Therefore, even when the screen section 100 is stored in the ceiling, the user will not be aware of the difference in color tone between the interior components and the surface layer 120, and will be able to view the outer surface 117 without any sense of incongruity with the interior components. Thus, the outer surface 117 (surface layer 120, screen section 100) will not impair the sense of unity of the interior (interior components) or the overall atmosphere of the vehicle.
[0018] Furthermore, by using the same material as the interior components for the surface layer 120 (projection surface 115, outer surface 117), the texture of the surface layer 120 becomes the same as that of the interior components. Therefore, the texture of the projection surface 115 or the outer surface 117 (surface layer 120, screen portion 100) does not detract from the overall sense of unity or atmosphere of the car's interior (interior components).
[0019] When a user sitting in the rear seat S2 views an image using the image display device 1, the screen unit 100 stored in the ceiling unit 310 is unfolded to position the projection surface 115 directly in front of the user. By projecting an image from the projector unit 200 onto the projection surface 115, the image is reflected off the projection surface 115 and visible to the user. For this reason, the interior trim is preferably in a lighter gray color scheme rather than a dark color scheme.
[0020] In the above-described screen part 100, the epidermal layer 120 (projection surface 115, outer surface 117) used the same material as the interior trim. However, FIG. 3 is a side cross-sectional view showing a screen part 101 having a structure different from that of the interior trim. The screen part 101 includes a base material layer 110, a light reflection layer 130, a light transmissive printing layer 140, and a light transmissive tactile layer 150. The screen part 1 is configured by laminating the light reflection layer 130, the light transmissive printing layer 140, and the light transmissive tactile layer 150 in this order on both surfaces of the base material layer 110 having a flat plate shape. Similar to FIG. 2, the projection surface 115 is formed by the plane on the rear (Re.) side of the vehicle of the screen part 101, and the outer surface 117 is formed by the plane on the front (Fr.) side of the vehicle.
[0021] The light reflection layer 130 has the property of reflecting the video (light) projected by the projector unit 200. Also, the light transmissive printing layer 140 and the light transmissive tactile layer 150 have the property of transmitting the video (light) projected by the projector unit 200. The video projected by the projector unit 200 onto the projection surface 115 of the screen part 101 passes through the light transmissive printing layer 140 and the light transmissive tactile layer 150, is reflected by the light reflection layer 130, and is visually recognized by the user.
[0022] The light transmissive printing layer 140 is a layer (layer material) that reproduces the color tone of the screen part 101 visually recognized by the user through printing. In the present embodiment, the light transmissive printing layer 140 is printed with the same color tone as the interior trim inside the vehicle. Specifically, in the case of the light transmissive printing layer on the projection surface 115 side, the same color tone as that of the door, chair, etc. located around the projection surface 115 is printed with light transmissive ink. In the case of the light transmissive printing layer 140 on the outer surface 117 side, the same printing as that of the ceiling surface, etc. is performed.
[0023] By performing printing with a color tone common to the interior parts inside the vehicle on the light-transmissive printing layer 140, the user no longer becomes aware of the difference in color tone between the color tone of the interior parts and the color tones of the projection surface 115 and the outer surface 117, and can visually recognize the screen unit 101 with respect to the interior parts without a sense of incongruity. Therefore, the unity of the interior (interior parts) of the vehicle and the overall atmosphere, etc. are not impaired by the screen unit 101 (projection surface 115, outer surface 117).
[0024] The light-transmissive tactile layer 150 is a layer (layer material) that reproduces the texture of the screen unit 101 recognized (tactile recognition) by the user. In the light-transmissive tactile layer 150 of the projection surface 115, a texture common to the interior parts (doors and chairs) located around the projection surface 115 developed by a light-transmissive resin formed in an uneven shape is reproduced. Also, in the light-transmissive tactile layer 150 of the outer surface 117, a texture common to the interior parts (ceiling surface, etc.) around the housed screen unit 101 is reproduced.
[0025] The common texture means that the texture obtained when the user touches the light-transmissive tactile layer 150 and the texture of the light-transmissive tactile layer 150 felt by the user based on visual information are textures that do not cause a sense of incongruity with respect to the interior parts. For example, the case where they have common touches, surface roughness, etc. respectively applies.
[0026] By reproducing (realizing) a texture common to the interior parts inside the vehicle as the texture of the light-transmissive tactile layer 150, the user no longer becomes aware of the difference in texture between the texture of the interior parts and the textures of the projection surface 115 and the outer surface 117, and can visually recognize the screen unit 101 with respect to the interior parts without a sense of incongruity. Thus, the unity of the interior (interior parts) of the vehicle and the overall atmosphere, etc. are not impaired by the screen unit 101 (projection surface 115, outer surface 117).
[0027] As described above, regarding the video display device of the present disclosure, although the video display device 1 has been described in detail by showing the video display device 1, the video display device 1 of the present disclosure is not limited to the configuration of the video display device 1 shown in the embodiment.
[0028] For example, in the screen section 100 shown in Figure 2, the case where the same material as the interior components is used for the surface layer 120 has been described, but the material of the surface layer 120 is not limited to the same material as the interior components. The material of the surface layer 120 can be any material that has a common color tone with the interior components, and different materials may be used. Similarly, the material of the surface layer 120 can be any material that has a common texture with the interior components, and different materials may be used.
[0029] If at least one of the color tone or texture of the surface layer 120 is the same as that of the interior components, the user will be less likely to notice the difference between the interior components and the surface layer 120, and will be able to view the surface layer 120 of the screen section 100 (projection surface 115, outer surface 117) without any sense of incongruity with the interior components. Therefore, the surface layer 120 (projection surface 115, outer surface 117, screen section 100) will not detract from the sense of unity or the overall atmosphere of the car's interior (interior components).
[0030] Furthermore, the video display device 1 shown in the embodiment was described in the case where the screen sections 100 and 101 are installed in the ceiling section 310 in a manner that allows them to be stored and unfolded. However, the installation position and storage / unfolding method of the screen sections 100 and 101 are not limited to those shown in the embodiment.
[0031] For example, the screen units 100 and 101 may be embedded in the back of the front seat S1. Even when embedded in the back of the front seat S1, if the color tone or texture of the projection surface 115 visible to the user is consistent with the color tone or texture of the back of the embedded front seat S1, the screen units 100 and 101 can be viewed without any sense of incongruity with the interior components, and the screen units 100 and 101 (projection surface 115) will not detract from the sense of unity of the interior (interior components) or the overall atmosphere of the vehicle.
[0032] Furthermore, the screen sections 100 and 101 may be structured to unfold and store not in the ceiling section 310, but in the door section inside the vehicle, the back of the front seat S1, the armrest of the rear seat S2, etc. If they are installed in such a position and are structured to unfold and store, and the color tone or texture of the projection surface 115 and outer surface 117 of the screen sections 100 and 101 are consistent with the interior components, the screen sections 100 and 101 can be viewed without any sense of incongruity with the interior components, and the screen section 100 (projection surface 115, outer surface 117) will not detract from the sense of unity of the interior (interior components) or the overall atmosphere of the vehicle.
[0033] Furthermore, although the video display device 1 according to the embodiment has been described in which the screen sections 100 and 101 are deployed and stored in the ceiling section 310 of the vehicle 300 with the upper end as a pivot axis, the structure for storing and deploying the screen sections 100 and 101 is not limited to this structure. For example, as disclosed in Patent Document 1, the screen sections 100 and 101 may be deployed and stored by sliding. Even with such a structure, it is possible to achieve the same effects as the video display device of this disclosure.
[0034] Furthermore, the image projected onto the projection surface in the video display device of this disclosure is not limited to a moving image, but may also be a still image such as a photograph. [Explanation of Symbols]
