Abstract

The invention discloses a liquid crystal display panel with compensable feed through effect, which comprises a plurality of groups of pixels, a grid driving circuit, a data driving circuit and a gamma voltage generator. Each group of pixels comprises a first pixel and a second pixel. The first pixel and the second pixel share one data wire, and the first and second pixels are coupled to first and second grid wires respectively. When the grid driving circuit drives the first grid wire, the data driving circuit writes data into the first pixel, and then the gamma voltage generator provides positive and negative gamma voltage to the data driving circuit. When the grid driving circuit drives the first and second grid wires at the same time, the data driving circuit writes data into the second pixel, and then the gamma voltage generator provides positive and negative gamma voltage added with compensation potential to the data driving circuit.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, and more particularly, to a liquid crystal display panel capable of compensating for the influence of the feed-through effect to display correct brightness. Background technique [0002] In the liquid crystal display panel, when the gate driving circuit drives a gate line, the data driving circuit can write data to the pixels connected to the gate line through the data line. However, when the gate driving circuit stops driving the gate line, the data stored in the pixels connected to the gate line will be affected by the voltage drop on the gate line, and will drop a feed-through potential (called feedthrough effect). In this way, the LCD panel may not display the correct brightness. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a liquid crystal display panel capable of compensating for the influence of the feedthrough effect to display correct bri...
