Abstract
A pixel structure and a method for generating drive voltages in the pixel structure are disclosed. The pixel structure comprises a first sub-pixel electrode, a first com-line, and second com-line. The first sub-pixel electrode is applied with a first drive voltage. The first com-line transmits a first com-voltage signal. The second com-line transmits a second com-voltage signal. The first drive voltage is derived by combining the first com-voltage signal and the second com-voltage signal.
