Pixel signal conversion method and device thereof

Abstract

The invention relates to a pixel signal conversion method and a device thereof. The method includes obtaining a first stimulus value signal, a second stimulus value signal, and a third stimulus valuesignal from an initial R sub-pixel signal, an initial G sub-pixel signal, and an initial B sub-pixel signal in a pixel signal. Further, a W sub-pixel signal is obtained by a minimum value in a stimulus value signal set consisting of a first stimulus value signal, a second stimulus value signal and a third stimulus value signal, and a converted R sub-pixel signal, a converted G sub-pixel signal anda converted B sub-pixel signal are sequentially obtained according to the minimum value. At last, convert R sub-pixel signal, convert G sub-pixel signal, convert B sub-pixel signal and W sub-pixel signal as converted pixel signal. Based on this, when the converted pixel signal is applied to the mixed color display composed of W, R, G, B sub-pixels, the display effect is closer to the actual performance of the original mixed color of R, G, B, which reduces the role bias defects of large vision and improves 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...
