1. A liquid crystal display apparatus comprising:
- a liquid crystal panel that displays video and a light source that illuminates the liquid crystal panel, which controls the emission luminance of the light source variably based on the feature quantity of an input video signal, wherein a genre information detecting means is provided for detecting genre information multiplexed with the input video signal and the luminance control characteristic of controlling the emission luminance of the light source variably based on the feature quantity of the input video signal is changed depending on the genre information detected by the genre information detecting means.

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).

12. 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 a genre determining means is provided for determining the genre of the video displayed on the liquid crystal panel and, when the genre of the video displayed on the liquid crystal panel is determined as an animation by the genre determining means, the emission luminance is decreased while maintaining constant chromaticity of the white. - View Dependent Claims (13, 14)
