Pixel signal conversion method and device

Abstract

The present application relates to a pixel signal conversion method and device, according to the initial first sub-pixel signal, the initial second sub-pixel signal and the initial third sub-pixel signal in the pixel signal, to obtain the corresponding first stimulus value signal, second stimulus value signal signal and the third stimulus value signal. Further, gain processing is performed according to the maximum value and minimum value in the stimulus value signal set, and the fourth sub-pixel signal is obtained from the minimum value, and the converted first sub-pixel signal, converted second sub-pixel signal and converted third sub-pixel signal are obtained. pixel signal. The converted first sub-pixel signal, converted second sub-pixel signal, converted third sub-pixel signal and fourth sub-pixel signal are used as converted pixel signals. Based on this, when the converted pixel signal is applied to a mixed-color color display composed of W, R, G, and B four-color sub-pixels, the display effect is closer to the actual performance of the original R, G, and B mixed-color colors, reducing the large viewing angle. Color cast defect, improve display effect.

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 ...
