Abstract

The invention provides a method and device for converting three-color data to four-color data. In the conversion method, firstly, among the three-stimulus value signals of the red sub-pixel in each pixel, the first stimulus value signal that has the greatest influence on the mixed color color is determined, and among the three-stimulus value signals of the green sub-pixel The second stimulus value signal that has the greatest influence on the color mixing color, and the third stimulus value signal that has the greatest influence on the color mixing color among the three stimulus value signals of the blue sub-pixel, and then according to the first stimulus value signal, the first stimulus value signal, The minimum value of the two stimulus value signals and the third stimulus value signal determines the stimulus value signal of the white sub-pixel, and calculates the gray scale value of the white sub-pixel according to the stimulus value signal of the white sub-pixel, so as to reduce The differences in projected brightness of the white sub-pixels in various directions further reduce the large viewing angle deviation.

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...
