Abstract
According to one embodiment, a display device includes a display panel including a display area which displays images, a plurality of light sources irradiating light to display an image on the display area and a control unit which sequentially causes the plurality of light source, which correspond to a plurality of areas divided from the display area, to emit light for each of the areas. The control unit repeatedly causes the light source, which corresponds to an area specified from the plurality of areas based on the image, to emit light during one frame period of displaying an image on the display area.
Claims14
A display device comprising:
- a display panel including a display area which displays images;
- a plurality of light sources irradiating light to display an image on the display area;
- a control unit which sequentially causes the plurality of light sources, which corresponds to a plurality of areas divided from the display area, to emit light for each of the areas;
- and
- a plurality of switches provided for the plurality of areas, wherein
- the control unit repeatedly causes the light source, which corresponds to an area specified from the plurality of areas based on the image, to emit light during one frame period of displaying an image on the display area,
- the plurality of light sources are arranged in a matrix along a first direction and a second direction,
- the plurality of areas extend along the first direction and are aligned along the second direction, and
- anodes of the light sources corresponding to each of the plurality of areas are electrically connected to a switch provided for the area.
A method executed by a display device comprising a display panel including a display area which displays images and a plurality of light sources irradiating light to display an image on the display area, the method comprising:
- when sequentially causing the plurality of light sources, which correspond to a plurality of areas divided from the display area, to emit light for each of the areas, repeatedly causing the light source, which corresponds to an area specified from the plurality of areas based on the image, to emit light during one frame period in which an image is displayed in the display area, wherein
- the display device comprises a plurality of switches provided for the plurality of areas,
- the plurality of light sources are arranged in a matrix along a first direction and a second direction,
- the plurality of areas extend along the first direction and are aligned along the second direction, and
- anodes of the light sources corresponding to each of the plurality of areas are electrically connected to a switch provided for the area.
