Patent number: 8730140Abstract: An LCD panel with function of compensating feed-through effect includes plural groups of pixels, a gate-driving circuit, a data-driving circuit, and a gamma voltage generator. Each group of pixels includes first pixel and second pixel. The first pixel and the second pixel share a data line, and are respectively coupled to first gate line and second gate line. When the gate-driving circuit drives the first gate line, the gamma voltage generator provides un-compensated gamma voltages for the data-driving circuit writing data to the first pixel. When the gate-driving circuit drives the first and the second gate lines at the same time, the gamma voltage generator provides gamma voltages compensated by a compensating voltage level for the data-driving circuit writing data to the second pixel. In this way, the feed-through effect suffered by the second pixel is compensated, so that each pixel of the LCD panel can display with correct brightness.Type: GrantFiled: June 10, 2013Date of Patent: May 20, 2014Assignee: AU Optronics Corp.Inventors: Fu-Yuan Liou, Shu-Huan Hsieh, Chung-Lung Li
