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, the corresponding first stimulus value signal and the second stimulus value are obtained. signal and the third stimulus value signal. A fourth sub-pixel signal is obtained according to the second minimum value of the gain-processed stimulus value signal set. The converted first sub-pixel signal, the converted second sub-pixel signal and the converted third sub-pixel signal are respectively obtained according to the difference between the stimulus value signal and the corresponding fourth stimulus value signal. The first sub-pixel signal, the second sub-pixel signal, the third sub-pixel signal, and the fourth sub-pixel signal are converted as converted pixel signals. When the converted pixel signal is applied to a mixed 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, B mixed color, and the large viewing angle is reduced. defects, improve the 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 B 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 eff...
