## Abstract

A pixel structure includes data lines disposed along a first direction, scan lines disposed along a second direction and pixel units periodically disposed along the first and the second directions. In a first pixel unit, a first switch element is coupled to a first scan line and a first data line, the second switch element is coupled to the first scan line, and a third switch element is coupled to the first scan line. In a second pixel unit, a fourth switch element is coupled to a second scan line, the first data line and the second switch element, and a fifth switch element is electrically coupled to the second scan line and the third switch element. In a third pixel unit, a sixth switch element is coupled to a third scan line, the first data line and the fifth switch element.
