Problems solved by technology

[0010] However, in the prior art as described above, due to the disturbance light around the backlight display device, the light reflected by Fresnel on the back surface of the diffusion layer on the surface diffuses and enters from the front direction of the viewing side, so there is a surface area of ​​the screen. Problems that look whitish

Embodiment approach 1

[0161] like figure 1 As shown, the display switching device 10 according to Embodiment 1 is a display switching device that switches the display image by switching the irradiation of light from the positions of the plurality of light sources 7, and includes a lens array 6 arranged so that the light emitted from the positions of the plurality of light sources is arranged A plurality of lenses through which the light of the lens array 6 is respectively transmitted; the display layer 4, which includes a pixel area 45a through which the light condensed by the respective lenses of the lens array 6 passes; the diffusion layer 3, which is located on the opposite side of the light source position with respect to the lens array 6, Diffusion of transmitted light. The diffusion layer 3 is optically bonded to the layer on the light source position side of the diffusion layer 3, or is composed of the same material as the layer on the light source 7 side of the diffusion layer 3 (display l...

Embodiment approach 2

[0166] As in the first embodiment described above, the diffusion layer 3 is conventionally disposed on the display layer 4 (on the visual recognition side) in order to prevent the light from the light source position from diffusing between the display layer 4 and the lens array 6 to prevent crosstalk from worsening. In this regard, the inventors of the present application found that the diffusion layer 3 can be arranged between the display layer 4 and the lens array 6 by adopting the structure shown in the following embodiments.

[0167] like figure 2 As shown, the display switching device 10 of the second embodiment may be arranged in the order of the lens array 6, the diffusion layer 3, and the display layer 4 from the light source position side. For example, from light source 7 ( figure 2 The lens array 6, the diffusion layer 3, and the display layer 4 are arranged in the order from the bottom) side, and the diffusion layer 3 and the lens array 6 are optically bonded via...

Embodiment approach 3

[0187] In the display switching device 10, the diffusion shape 61 for diffusing the light transmitted through the lens array 6 may be formed on the display layer 4 side of the lens array 6. As shown in FIG. For example, as Figure 13 As shown, the display layer 4 and the lens array 6 may be arranged in this order from the visual recognition side, and the diffusion shape 61 may be formed on the display layer 4 side of the lens array 6.

[0188] According to such a configuration, since the diffusion layer and the lens array 6 are formed integrally, it is possible to suppress Fresnel reflection caused by disturbing light from the visual recognition side. In addition, since the diffusion layer may not be provided, the manufacturing cost of the display switching device 10 can be suppressed.

[0189] In the display switching device 10 described above, the diffusion shape 61 of the lens array 6 is formed of a plurality of lens shapes. In this structure, the height of the diffusion ...

Abstract

The invention provides a display switching device, a button device for a game machine, and a switch, which can restrain a display screen of a display layer from becoming white by visually recognizing reflected light of interference light in a pixel region by a user. The display switching device (10) switches the display image by switching the irradiation of light from the plurality of light source positions (7). A display switching device is provided with: a lens array (6) in which a plurality of lenses for transmitting light emitted from a plurality of light source positions are arranged; a display layer (4) including a pixel region through which the light converged by each lens of the lens array passes; and a diffusion layer (3) which is located on the opposite side of the light source position with respect to the lens array and diffuses the transmitted light. The diffusion layer is optically bonded to a layer located on the light source position side of the diffusion layer or is made of the same material as the layer located on the light source side of the diffusion layer.

Description

technical field [0001] The present invention relates to a display switching device, a button device and a switch for a game machine including the display switching device. Background technique [0002] Disclosed is a display switching device that transmits light from a plurality of light sources through a lens array composed of a plurality of minute lenses, condenses (condenses) light on a display layer, and diffuses the light through a diffusion layer. [0003] For example, in Patent Document 1, a backlight display device for automatic visual inspection of lenticular image cards is disclosed, which includes an illumination source that selectively illuminates individual images formed on a lenticular medium by design. In this backlit display device, the illumination source of the display directs light through the lenticular side of the lenticular image card in order to sequentially illuminate the individual images in sequence and to suit the visual distance of the card and th...
