Abstract
In a display apparatus having a plurality of pixel parts, each pixel part receives a data signal in response to a present gate signal and charges first and second pixel voltages having the same voltage level. A plurality of voltage controllers includes a level-down part to lower a voltage level of the second pixel voltage using a previous pixel voltage charged in a previous frame in response to a next gate signal and a level-up part to receive the lowered second pixel voltage in response to the next gate signal to boost up a voltage level of the first pixel voltage.
