Abstract

The invention provides a method and device for conversion of tri-color data to four-color data. According to the conversion method, gain processing is carried out on a first stimulus value signal having the greatest influence on the mixed color in a tristimulus value signal of red sub-pixel in each of the pixel points, a second stimulus value signal having the greatest influence on the mixed colorin a tristimulus value signal of green sub-pixel, and a third stimulus value signal having the greatest influence on the mixed color in a tristimulus value signal of blue sub-pixel, so that the stimulus value signal of white sub-pixel can be adjusted according to the brightness of the pixel points, and subsequently a gray-scale value of the white sub-pixel can be calculated according to the stimulus value signal of the white sub-pixel, thus enhancing the light penetration rate and screen brightness, also reducing the projection brightness difference of the white sub-pixel in all directions atthe same time, and further improving the situation of large view angle color cast.

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...
