ABSTRACT:
A pixel structure is provided. A data line and a scan line are disposed over a substrate. A first, a second, and a third thin film transistors (TFT) are electrically connected with the data line and the scan line respectively. A first width-to-length ratio, a second width-to-length ratio and a third width-to-length ratio of the first, second and third TFTs are the same. An impedance layer and the first TFT are connected in series. A first, a second, and a third pixel electrodes are electrically connected with the first, the second and the third TFTs respectively. A first, a second, and a third common line are disposed below the first, second and third pixel electrodes respectively. The first and second common lines are electrically connected to a first voltage and the third common line is electrically connected to a second voltage.
