Patent number: 8773418Abstract: By following properties that there is coupled noise, which is coupled from a display panel, within at least one common voltage used on the display panel, the at least one common voltage is fed-back into a pixel electrode driving module, and driving voltages are generated accordingly, so that the generated driving voltages carry noises closes to coupled noises of the display panel. As a result, while the driving voltages carrying noises from the at least one common voltage, the pixel electrode driving module is capable of driving a corresponding pixel electrode with a stable voltage difference, and thereby capable of relieving horizontal crosstalk and raising a display quality of the display panel.Type: GrantFiled: May 13, 2010Date of Patent: July 8, 2014Assignee: AU Optronics Corp.Inventors: Sheng-Liang Hsieh, Chun-Kuei Wen, Shih-Chieh Kuo, Che-Hsien Chen, Chao-Ching Hsu
