  • REDUCED COMPONENT DISPLAY DRIVER AND METHOD
    Publication number: 20080055227
    Abstract: A display driver circuit for driving display elements in a row of a display array, includes an m input, n-bit input multiplexer; a digital to analog converter, and a one input, m output, analog output multiplexer. A clock source, clocks the input and output multiplexers, to sequentially provide an analog output corresponding to one of said m n-bit inputs, at a corresponding one of said m outputs of said output multiplexer.

  • REDUCED COMPONENT DIGITAL TO ANALOG DECODER AND METHOD
    Publication number: 20080055134
    Abstract: An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.
