Abstract

The invention provides a compensation circuit of a liquid crystal display panel, comprising a plurality of source scanning lines, a plurality of grid scanning lines, a plurality of inverse grid scanning lines, a plurality of pixel units and a plurality of compensation units. Each of the source scanning lines is used for outputting a data voltage, each of the grid scanning lines is used for outputting a control signal, and each of the inverse grid scanning lines is used for outputting an inverse control signal; a pixel unit of the plurality of pixel units is discharged to a corresponding gray scale voltage according to the corresponding control signal and the corresponding data voltage, and a corresponding compensation unit is used for supplying a compensation voltage to compensate the voltage of the corresponding the gray scale according to the inverse control signal.

Description

technical field [0001] The invention relates to a compensation circuit of a liquid crystal panel, in particular to a compensation circuit for improving the flicker phenomenon of the liquid crystal panel. Background technique [0002] Please refer to Figure 1A , Figure 1A It is a schematic diagram illustrating a pixel unit 100 in a liquid crystal panel in the prior art. When the thin-film transistor (thin-film transistor, TFT) 104 in the pixel unit 100 receives the control signal VG output by the gate scan line 102 as a high potential VDDG, the thin-film transistor 104 is turned on and the source scan line 106 is turned on according to the data voltage VD. The liquid crystal capacitor Clc in the pixel unit 100 is charged and discharged to a corresponding grayscale voltage Vgray. At this time, the gate potential of the thin film transistor 104 is the potential VDDG of the control signal VG. Additionally, if Figure 1A As shown, Cgd is the parasitic capacitance of the thin ...
