Method of driving liquid crystal display panel

Abstract

A method of driving a liquid crystal display panel is provided. The liquid crystal display panel includes a first scan line, a second scan line, a data line, a first pixel and a second pixel. The first pixel has a first switch, a second switch and a first pixel electrode. The second pixel has a third switch and a second pixel electrode. The driving method includes the following steps. At first, during a first time period, the first scan line and the second scan line are enabled at the same time, a first pixel voltage is inputted to the data line. Then, during a second time period, the first scan line is enabled, the second scan line is disabled, and a second pixel voltage is inputted to the data line. The second time period is shorter than the first time period.
