Abstract

The invention relates to a method and device for conversion of tri-color data to four-color data. According to the conversion method, a pixel point corresponded yield value is determined, and gain processing is carried out, a normalized stimulus value signal of white sub-pixel is determined according to a minimum value of gain processed stimulus value signals, the normalized stimulus value signalof the white sub-pixel is utilized to determine a tristimulus value signal thereof, the normalized stimulus value signals of red, green and blue sub-pixels are respectively determined according to thegain processed stimulus value signals and the tristimulus value signal of the white sub-pixel, so that the gain of the white sub-pixel can be consistent with the pixel point gain, and the influence of the white sub-pixel can be eliminated from the normalized stimulus value signals of the red, green and blue sub-pixels, while the light penetration rate and screen brightness are improved, the projection brightness difference of the white sub-pixel in all directions is reduced, and the situation of large view angle color cast is improved.

Description

technical field [0001] The present application relates to the field of display, 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 m...
