Abstract
An exemplary driving method of a display panel with half-source-driving structure is provided. The display panel includes at least one pixel each using a capacitor to store a voltage. A terminal of the capacitor is adapted to receive a display data inputted from a data line, and another terminal of the capacitor is electrically coupled to a common electrode. The driving method includes: obtaining a direct current power signal; coupling an alternating current signal with the direct current power signal to generate a common electrode driving signal; and applying the common electrode driving signal to the common electrode. A rising time of a rising edge and a falling time of a falling edge of the common electrode driving signal are modified to improve a V-line mura phenomenon of the display panel.
