  • Patent number: 8471801
    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.

  • Publication number: 20130155035
    Abstract: A method for driving a pixel circuit, which is adapted to drive a first pixel circuit coupled to a first gate line and a second pixel circuit coupled to a second gate line, is disclosed. The first pixel circuit receives display data before the second pixel circuit does. The method provides only one first enable pulse to the first gate line in a frame, and provides a second enable pulse and a third enable pulse to the second gate line in the same frame. The starting time of the second enable pulse is in an enabled time period of the first enable pulse, and the enabled time period of the third enable pulse is after the enabled time periods of the first and second enable pulses.
