Claim:
1. An image conversion method for converting RGB signal to RGBW signal, comprising: converting received RGB input signals of respective pixels in each frame into corresponding RGB luminance input values, respectively; determining a substitution rate of a W luminance output value of the respective pixels in each frame, according to the RGB luminance input values of the respective pixels in each frame, and accumulated proportions of RGB luminance output values and the W luminance output value in RGBW luminance output values of the respective pixels within a preset time before each frame; determining the RGBW luminance output values of the respective pixels in each frame, according to the determined substitution rate of the W luminance output value and the RGB luminance input values of the respective pixels in each frame; converting the determined RGBW luminance output values of the respective pixels in each frame into corresponding RGBW output signals, respectively, and outputting the same.
