Abstract
A display apparatus is provided which can achieve suitable screen display luminance depending on video content as well as can reduce power consumption sufficiently. A liquid crystal display apparatus includes a liquid crystal panel that displays video and a light source that illuminates the liquid crystal panel, and the emission luminance of the light source is controlled depending on the genre of the video displayed on the liquid crystal panel. The emission luminance of the light source is adjusted while maintaining approximately constant white chromaticity (white balance).
Claims16
A liquid crystal display apparatus comprising:
- a liquid crystal panel that displays video, and a light source that illuminates the liquid crystal panel,
- wherein an emission luminance characteristic of the light source for a feature quantity of an input video signal is changed depending on a genre of video displayed on the liquid crystal panel.
A liquid crystal display apparatus comprising:
- a liquid crystal panel that displays video, and a light source that illuminates the liquid crystal panel with white light,
- wherein, depending on a genre of the video displayed on the liquid crystal panel, increase and decrease of the emission luminance of the light source are adjusted while maintaining approximately constant chromaticity of the white.
