Abstract:
1. A display, comprising: a plurality of pixels, each pixel of the plurality of pixels comprising four sub-pixels for displaying an image according to four color image values; and a signal transformation unit for transforming tricolor image values of the pixels into four color image values of the pixels; wherein among m pixels of the pixels having color saturation values of tricolor image values between 0.7 and 1, a ratio of Wmax and max{min [R, G, B] } of n pixels having similar color saturation values is not larger than 1, to smooth a relationship between the color saturation values of the n pixels and the ratio of Wmax and max{min[R,G,B]} of n pixels and reduce a gray level overlapping effect, where Wmax denotes a largest value of n white color image values of four color image values of the n pixels, and max{min[R,G,B]} denotes a largest value of n smallest tricolor values of the tricolor image values of the n pixels.
