Display device, drive method therefor, and electronic apparatus
First Claim
1. A display device comprising:
- a light source section having multiple light sources arranged in a plane to emit light in illumination colors including three primary colors of light;
a display section configured to display an image in monochrome color by modulating the light emitted from the light source section; and
a display control section configured to drive the light source section and the display section in a field sequential system in which the illumination colors of the light sources are switched for respective fields in one frame to perform color display;
wherein the display control section includesdetermining means for determining a degree of white or a degree of complementary color of the light sources on a basis of an amount of lighting of each of the illumination colors of the light sources, the amount of lighting being determined in accordance with a signal of a color image to be displayed,setting means for setting white components or complementary-color components of a color determined by a mixing ratio of the illumination colors, on a basis of a result of the determination performed by the determining means, andallocating means for allocating the white components or the complementary-color components, set by the setting means, to the fields.

Abstract
A display device includes: a light source section having multiple light sources to emit light in illumination colors including three primary colors of light; a display section for displaying an image in monochrome color by modulating the light emitted from the light source section; and a display control section for driving the light source section and the display section in a field sequential system. The display control section includes a determining section for determining a degree of white or a degree of complementary color of the light sources on the basis of an amount of lighting of each of the illumination colors of the light sources, a setting section for setting white components or complementary-color components of a color determined by a mixing ratio of the illumination colors, and an allocating section for allocating the set white components or the complementary-color components to the fields.
