DISPLAY DRIVING DEVICE, DISPLAY APPARATUS, AND METHOD OF DRIVING THEM
First Claim
1. A display driving device for driving a plurality of display pixels provided with a light emitting element, which performs color display and has any one of a plurality of light emission colors, comprising:
- a signal converter, which is supplied a display data, which corresponds to said each display pixel and includes a plurality of color components corresponding to said plurality of light emission colors and generates a gradation signal, which corresponds to the predetermined number of two or more display pixels having the light emtting element of different light emission colors from each other and is obtained by conversion of the display data,wherein the signal converter comprises;
a gamma correction curve generator which, based on a single conversion characteristic, generates gamma correction curves different from each other which correspond to the color components corresponding to the light emission color of each of the light emitting elements in the predetermined number of display pixels and set a relation between a value of the display data and a value of the gradation signal; and
a gradation signal generator which converts the color component of the display data with the use of the generated gamma correction curve corresponding to said each color component and generates in a time series manner the gradation signal corresponding to the predetermined number of display pixels.
