Abstract

This application relates to a pixel signal conversion method and device, which obtains the first stimulus value signal, the second stimulus value signal and the third stimulus value signal according to the initial R sub-pixel signal, the initial G sub-pixel signal and the initial B sub-pixel signal in the pixel signal. value signal. Further, the W sub-pixel signal is obtained through the minimum value in the stimulus value signal set composed of the first stimulus value signal, the second stimulus value signal and the third stimulus value signal, and the converted R sub-pixel signal, R sub-pixel signal, and Convert G sub-pixel signal and convert B sub-pixel signal. Finally, the converted R sub-pixel signal, converted G sub-pixel signal, converted B sub-pixel signal and W 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 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...
