ABSTRACT:
An IC driver mounted on a LCD display package contains a sensor for determining temperature of the LCD cell, and a digital value of the temperature is serially transmitted to a remote microprocessor which determines compensated voltage and sends voltage command data back to the IC driver which produces a drive voltage by a charge pump. A digital code on the LCD cell identifies cell response characteristics and the code is used by the microprocessor to calculate the desired voltage. A ROM in the IC driver stores many bit-mapped images which are selected by the microprocessor for display.
