Abstract
A backlight unit of the present disclosure includes: a backlight including a plurality of light-emitting devices that are allowed to emit light at mutually different timings and include a first light-emitting device and a second light-emitting device; and a controller that controls a light emission operation of the backlight to cause the first light-emitting device and the second light-emitting device to emit light with mutually different average light emission intensities in a first sub-frame period of a plurality of sub-frame periods provided corresponding to a frame period.
Claims16
A backlight unit, comprising:
- a backlight including a plurality of light-emitting devices that are allowed to emit light at mutually different timings and include a first light-emitting device and a second light-emitting device;
- and
- a controller that controls a light emission operation of the backlight to cause the first light-emitting device and the second light-emitting device to emit light with mutually different average light emission intensities in a first sub-frame period of a plurality of sub-frame periods provided corresponding to a frame period.
A display apparatus, comprising:
- a display section;
- and
- a backlight unit, wherein
- the backlight unit includes
- a backlight including a plurality of light-emitting devices that are allowed to emit light at mutually different timings and include a first light-emitting device and a second light-emitting device, and
- a controller that controls a light emission operation of the backlight to cause the first light-emitting device and the second light-emitting device to emit light with mutually different average light emission intensities in a first sub-frame period of a plurality of sub-frame periods provided corresponding to a frame period.
A display apparatus, comprising:
- a map generator that generates a luminance map on a basis of image data of a frame image;
- a display section that displays the frame image by scanning in a first direction;
- a backlight that includes a plurality of light-emitting devices arranged side by side in the first direction and a second direction intersecting with the first direction, and performs a light emission operation by scanning in the first direction;
- and
- a controller that generates light emission distribution information in the first direction in each of a plurality of sub-frame periods provided corresponding to a frame period, and controls the light emission operation of the backlight on a basis of the luminance map and the light emission distribution information.
A light emission control method, comprising:
- setting a plurality of sub-frame periods corresponding to a frame period;
- and
- controlling a light emission operation of a backlight to cause a first light-emitting device and a second light-emitting device in the backlight to emit light with mutually different average light emission intensities in a first sub-frame period of the plurality of sub-frame periods.
