Abstract:
A single integrated circuit device for controlling column and row drivers of an active matrix display comprising:row control circuitry for generating digital timing and control signals which are provided to the row drivers;column control circuitry for generating digital timing and control signals which are provided to the column drivers;analog circuitry for generating select analog voltages and providing the select analog voltages to the column drivers for driving a plurality of column electrodes of the active matrix display,registers coupled to the analog circuitry for storing digital values which correspond with the select analog voltages which are provided to the column drivers,a multiplexer coupled to the registers for selecting between the digital values; anda digital-to-analog converter within the analog circuitry for receiving the digital value selected by the multiplexer and providing to the column drivers the select analog voltage level which corresponds with the digital value selected by the multiplexer.
