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.

A data line driving method adapted in a display panel driver circuit is provided. The display panel driver circuit comprises a plurality rows of gate lines and a plurality of data driver stages each corresponding to a data line group, wherein the data line driving method comprises the steps of: turning on the data driver stages in a first sequential order to input a first frame data in the data line groups corresponding to the data driver stages in each gate line activation time within a first frame period; and turning on the data driver stages in a second sequential order which is opposed to the first sequential order to input a second frame data in the data line groups corresponding to the data driver stages in each gate line activation time within a second frame period; wherein the first and the second frame period are two interlaced periods next to each other.
