Display device
According to an aspect, a display device includes: a liquid crystal display panel provided with a plurality of pixels; and a light source provided with a plurality of light emission points and configured to emit light to the pixels of the liquid crystal display panel. A ratio of a pitch between the pixels arranged in a first direction to a pitch between the light emission points arranged in the first direction is 1:4n or 1:6n, wherein n is a natural number. A width of each light emission point in the first direction is larger than a width of each pixel in the first direction.
1 . A display device comprising:
a liquid crystal display panel provided with a plurality of pixels;
a light source provided with a plurality of light emission points and configured to emit light to the pixels of the liquid crystal display panel;
an acquirer configured to acquire viewpoint information of a user viewing the liquid crystal display panel; and
a controller configured to control image display through operation of the pixels based on the viewpoint information, wherein
a ratio of a pitch between the pixels arranged in a first direction to a pitch between the light emission points arranged in the first direction is 1:4n or 1:6n,
n is a natural number, and
a width of each light emission point in the first direction is larger than a width of each pixel in the first direction,
each pixel includes a plurality of sub pixels arranged in the first direction,
the viewpoint information includes information related to positions of a plurality of viewpoints and information indicating an arrangement direction of the viewpoints, and
the controller drives display of some or all of sub pixels included in at least the pixels positioned on straight lines connecting the light emission points and the viewpoints based on a relative rotation angle between the liquid crystal display panel and the arrangement direction and a relative positional relation between each viewpoint and each light emission point.
2 . The display device according to claim 1 , wherein
the pixels are arranged in a matrix having a row-column configuration in the first direction and a second direction orthogonal to the first direction,
a ratio of a pitch between the pixels arranged in the second direction to a pitch between the light emission points arranged in the second direction is 1:4n or 1:6n, and
a width of each light emission point in the second direction is larger than a width of each pixel in the second direction.
3 . The display device according to claim 1 , wherein the controller causes, among the sub pixels included in a pixel adjacent to a pixel including a sub pixel at a position intersecting an optical axis between the viewpoint and the light emission point, a sub pixel disposed closer to an intersection point with the optical axis between the viewpoint and the light emission point to transmit light therethrough.
4 . The display device according to claim 1 , wherein the acquirer includes
an image capturer configured to capture an image of the user, and
a processor configured to identify the arrangement direction, the relative rotation angle, and the relative positional relation for right and left eyes of the user based on the captured image of the user.
