DRIVER CIRCUIT FOR A LIQUID CRYSTAL DISPLAY

摘要

A display driver for generating a drive signal for driving a display element in response to a multi-bit input signal, the display driver comprising: an adding unit arranged to repetitively perform addition of the input signal to a feedback signal to generate a multi-bit sum signal and a single-bit carry signal representative of the sum of the input signal and the feedback signal; and a latch for receiving the sum signal for each repetition and storing it to form the feedback signal for the next repetition; the driver being arranged to form the drive signal in dependence on the carry signal.
