Abstract:
1. A display apparatus, comprising: a plurality of gate lines to sequentially receive a gate signal; a plurality of data lines insulated from the gate lines, the data lines to receive a data signal; a plurality of pixel parts, each pixel part comprising a first pixel to receive the data signal to charge a first pixel voltage in response to a present gate signal and a second pixel to receive the data signal to charge a second pixel voltage in response to the present gate signal; and a plurality of voltage controllers, each voltage controller comprising a level-down part and a level-up part and being connected with the pixel parts in one-to-one correspondence, the 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, the level-down part being configured to be electrically connected with the first pixel in response to the next gate signal, and the level-up part to receive the lowered second pixel voltage to boost up a voltage level of the first pixel voltage in response to the next gate signal.
