Abstract
An apparatus for driving a display includes a shift register, a first latch unit, a second latch unit, a data comparison unit and a level select unit. The shift register generates multiple latch signals according to a sync signal. The first latch unit latches a data signal in response to the latch signals to obtain multiple first data corresponding to multiple channels. The second latch unit is coupled to the first latch unit and latches the first data of the channels as multiple second data in response to a latch data signal. The data comparison unit responds to the latch data signal to respectively compare the first data and the second data corresponding to the same channel to output multiple third data corresponding to the channels. The level select unit selects multiple voltage levels corresponding to the channels according to the third data.
