Display apparatus and method of driving the same

摘要

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.

1. A display apparatus, comprising:
a first substrate; a first gate line disposed on the first substrate; a second gate line extending substantially parallel to the first gate line; a storage pattern disposed on the same layer as the first gate line and the second gate line; a data line crossing the first gate line and the second gate line; a first sub pixel electrode and a second sub pixel electrode disposed on the first substrate; a first thin film transistor comprising a first terminal connected to the first gate line, a second terminal connected to the data line, and a third terminal connected to the first sub pixel electrode; a second thin film transistor comprising a first terminal connected to the first gate line, a second terminal connected to the data line, and a third terminal connected to the second sub pixel electrode; a third thin film transistor comprising a first terminal connected to the second gate line, a second terminal connected to the second sub pixel electrode, and a third terminal connected to a first opposite electrode, the first opposite electrode overlapping with the storage pattern; and a fourth thin film transistor comprising a first terminal connected to the second gate line, a second terminal connected to the third terminal of the third thin film transistor, and a third terminal connected to a second opposite electrode overlapping with the first sub pixel electrode, wherein a width of the storage pattern is larger than a width of the first opposite electrode when measured along a line extending in a direction of the data line.
