A process of operating a PWM display system wherein some display data bits are assigned substantially equal time weights. Display data codewords are defined for every pixel intensity value to form display data codeword tables so that there are at least as many display data codeword tables as the number of display data bits with substantially equal time weights. The display pixel is subsequently operated in a digital manner according to the display data codeword in the selected display data codeword table to display a desired pixel intensity value. The display data codeword tables are configured so that immediately adjacent display pixels are operated so that identical pixel intensity values are displayed with different temporal sequences.
