DISPLAY DEVICE AND ELECTRIC APPARATUS
First Claim
1. A display device comprising:
- a first light source having a blue illuminant that emits blue light and a green phosphor provided to cover the blue illuminant,a second light source that emits light in a complementary relationship with the light from the first light source,a display element comprising pixels of plural colors that display colors different from each other, configured to be capable of displaying white color with the pixels of plural colors, where lights from the first light source and the second light source enter,an illumination control part configured to be capable of controlling lighting of the first light source and the second light source independently from each other, anda display control part that conducts a drive control of the display element for each pixel with use of an inputted video signal,the display control part converts the inputted video signal to a video signal for the former half of one frame time period and a video signal for the latter half of the one frame time period, on the basis of the inputted video signal and the colors of lights from the first light source and the second light source in the former half and the latter half of the one frame time period, and outputs the video signals toward the display element.

Abstract
It is an object of the present invention to provide a display device in which the color purity of red display can be improved and also to provide an electric apparatus using the same. A controller (19) of the display device is provided with an illumination control part (22) that turns on a light-emitting diode (first light source) (9C) to emit a cyan light during the former half of one frame time period and turns on a light-emitting diode (second light source) (9M) to emit a magenta light during the latter half of the one frame time period. In addition, a video signal converting part (21b) is provided to a panel control part (display control part) 21. The video signal converting part 21b converts an inputted video signal to video signals for the former half and the latter half of the one frame time period, on the basis of the inputted video signal and the colors of the lights in the former half and the latter half of the one frame time period. The present invention is applicable to, for example, a television receiver having a transmission type liquid crystal display device.
