Abstract

A display switching device (10) is provided, which switches a display image (P) by switching irradiation of lights from positions of a plurality of light sources (7). The display switching device includes: a lens array (6) in which a plurality of lenses are arranged; and a display part (45) including a plurality of pixel regions (45a) arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the positions of the plurality of light sources (7) with each of the lenses of the lens array (6), passes. A transmittance in each of the pixel regions (45a) is set corresponding to a predetermined stationary pattern. A total area of the pixel regions (45a) in the display part (45) is 60% or less of a total area of a sum of the pixel regions (45a) and the pixel surrounding regions (45b).

First claim

a lens array in which a plurality of lenses are arranged; and a display part, wherein the display part comprises: a plurality of pixel regions arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the plurality of light source positions with each of the lenses of the lens array, passes; and a pixel surrounding region arranged around each of the pixel regions and having a constant transmittance, wherein a transmittance in each of the pixel regions is set corresponding to a predetermined stationary pattern, and a total area of the pixel regions in the display part is 60% or less of a total area of a sum of the pixel regions and the pixel surrounding regions.

2 . The display switching device according to claim 1 , wherein the lens array comprises a plurality of lenses arranged two-dimensionally.

3 . A display switching device, switching a display image by switching irradiation of lights from a plurality of light source positions, the display switching device comprising:
a lens array in which a plurality of lenses are arranged; and a display part comprising a plurality of pixel regions arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the plurality of light source positions with each of the lenses of the lens array, passes, wherein a transmittance in each of the pixel regions is set corresponding to a predetermined stationary pattern, wherein a location dependency of a color or a reflectance in the display part resulting from a disturbance light emitted from a side opposite to a side where the lens array is arranged with respect to the display part is lower than a location dependency of a transmittance in the display part resulting from a light from a light source.

4 . A display switching device, switching a display image by switching irradiation of lights from a plurality of light source positions, the display switching device comprising:
a lens array in which a plurality of lenses are arranged; and a display part, wherein the display part comprises: a plurality of pixel regions arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the plurality of light source positions with each of the lenses of the lens array, passes; and a pixel surrounding region arranged around each of the pixel regions and having a constant transmittance, wherein a transmittance in each of the pixel regions is set corresponding to a predetermined stationary pattern, and with respect to reflection resulting from a disturbance light emitted from a side opposite to a side where the lens array is arranged with respect to the display part, a variation width of a reflectance of regions including both the pixel region and the pixel surrounding region in the plurality of pixel regions is smaller than a variation width of a reflectance in only the pixel region.

5 . The display switching device according to claim 4 , wherein a reflectance of the pixel surrounding region is constant.

6 . The display switching device according to claim 4 , wherein the display part further comprises a pixel surrounding region having a constant transmittance around each of the pixel regions, and
the pixel surrounding region blocks a light from the side where the lens array is arranged.

7 . The display switching device according to claim 4 , wherein a reflectance of the pixel surrounding region differs according to a reflectance of the corresponding pixel region.

8 . The display switching device according to claim 7 , wherein a dummy opening is provided in the pixel surrounding region at a position different from a position where the light is condensed by each of the lenses of the lens array.

9 . The display switching device according to claim 4 , wherein the display part further comprises a pixel surrounding region having a constant transmittance around each of the pixel regions, and
a total area of the pixel regions in the display part is 60% or less of a total area of a sum of the pixel regions and the pixel surrounding regions.

10 . A display switching device, switching a display image by switching irradiation of lights from a plurality of light source positions, the display switching device comprising:
a lens array in which a plurality of lenses are arranged; and a display part, wherein the display part comprises: a plurality of pixel regions arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the plurality of light source positions with each of the lenses of the lens array, passes; and a pixel surrounding region arranged around each of the pixel regions and having a constant transmittance, wherein a transmittance in each of the pixel regions is set corresponding to a predetermined stationary pattern, and a color or a reflectance resulting from a disturbance light emitted from a side opposite to a side where the lens array is arranged with respect to the display part differs depending on a location of the pixel surrounding region.

11 . A display switching device, switching a display image by switching irradiation of lights from a plurality of light source positions, the display switching device comprising:
a lens array in which a plurality of lenses are arranged; and a display part comprising a plurality of pixel regions arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the plurality of light source positions with each of the lenses of the lens array, passes, wherein a transmittance in each of the pixel regions is set corresponding to a predetermined stationary pattern, wherein the display switching device further comprises a dimming member, absorbing or diffusing a light, on a side opposite to a side where the lens array is arranged with respect to the display part.
