Pixel signal conversion method and device

Abstract

The present invention relates to a pixel signal conversion method and device. The pixel signal conversion method includes: obtaining a corresponding first stimulus value signal, a corresponding secondstimulus value signal and a corresponding third stimulus value signal according to an initial first sub-pixel signal, an initial second sub-pixel signal, and an initial third sub-pixel signal in a pixel signal; performing gain processing according to the maximum value and a minimum value in a stimulus value signal set, and obtaining a fourth sub-pixel signal from the minimum value, and obtaininga conversion first sub-pixel signal, a conversion second sub-pixel signal, and a conversion third sub-pixel signal; taking the conversion first sub-pixel signal, the conversion second sub-pixel signal, the conversion third sub-pixel signal and the fourth sub-pixel signal as the converted pixel signal. Based on this, when the converted pixel signal is applied to the mixed color display composed ofW, R, G, B four-color sub-pixels, the display effect is closer to the actual performance of the original R, G, B mixed color, large viewing angle color-biased defects are reduced, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of liquid crystal display technology, in particular to a pixel signal conversion method and device. Background technique [0002] In a traditional liquid crystal display, the three-color light sources generated by the three sub-pixels of R (Red), G (Green), and B (Blue) are generally mixed to produce the desired display color. R, G, and B three-color light sources are absorbed by the photoresist material of the three sub-pixels of R, G, and B to absorb the light bands of the non-R, G, and blue sub-pixel units, so that the three sub-pixels of R, G, and B produce corresponding R, G, B three-color light source. [0003] With the improvement of the resolution of the liquid crystal display, the increase of sub-pixels superimposes the decrease of the aperture ratio of the pixel corresponding to the sub-pixels, resulting in the loss of the transmittance of the high-resolution display and the decrease of the light ...
