Abstract: According to an aspect, a display apparatus includes: a plurality of light sources; a display device irradiated with light from the light sources; and a controller. The display area includes a plurality of partial areas corresponding to the light sources on a one-to-one basis. Each of the partial areas includes a first area and a second area, the first area being irradiated with light from a first light source that corresponds thereto, and the second area being irradiated with light from the first light source and a second light source adjacent to the first light source. The controller controls an operation of the first light source based on whether the first area requires the light from the first light source and whether the second area obtains light required for display output by receiving the light from the second light source.

Abstract: A display device is disclosed. In one embodiment, it includes a light source, a light guide including an entrance surface facing the light source and an exit surface from which light incident on the entrance surface exits, and a display panel including a display area in which a plurality of display pixels are arranged, with the display area facing the exit surface. The display panel is configured to selectively transmit light incident on the display area for displaying an image in the display area by driving the display pixels. A dimming panel including a dimming area faces the display area and the exit surface, and is configured to change a transmittance of light incident on the dimming area for each portion in the dimming area.
