Abstract

The invention provides a method and a device for converting three-color data to four-color data. The conversion method comprises the steps of: determining a normalized stimulus value signal of a whitesub-pixel according to a minimum value of a first stimulus value signal after gain processing, a second stimulus value signal after gain processing and a third stimulus value signal after gain processing; and regarding a difference value between the first stimulus value signal after gain processing and a red stimulus value signal in a tristimulus value signal of the white sub-pixel as a normalized stimulus value signal of a red sub-pixel, regarding a difference value between the second stimulus value signal after gain processing and a green stimulus value signal in the tristimulus value signal of the white sub-pixel as a normalized stimulus value signal of a green sub-pixel, and regarding a difference value between the third stimulus value signal after gain processing and a blue stimulusvalue signal in the tristimulus value signal of the white sub-pixel as a normalized stimulus value signal of a green sub-pixel, so as to improve the penetration rate of light and screen brightness while solving the problems of large viewing angle color cast and color distortion.

Description

technical field [0001] The invention relates to the display field, in particular to a method and device for converting three-color data to four-color data. Background technique [0002] Generally, the liquid crystal display generates the color to be displayed by mixing the three-color light sources generated by the red sub-pixel, green sub-pixel and blue sub-pixel. The red, green and blue three-color light source is absorbed by the absorbing photoresist material in the red, green and blue sub-pixels (that is, the red sub-pixel, the green sub-pixel and the blue sub-pixel) to absorb the non-red, green and blue light bands, so that the red, green and blue sub-pixels The pixels generate corresponding red, green and blue light sources. For example, the red photoresist material of the red sub-pixel absorbs the visible light in the non-red wavelength range, and corresponds to the visible light penetration in the red wavelength range. Similarly, the green photoresist material of th...
