Liquid crystal display panel and common voltage compensation method, device thereof
Abstract:
Disclosed is a liquid crystal display panel, comprising an array substrate and a common voltage compensation circuit. The array substrate comprises scan lines, data lines, common electrode lines and sub pixel units arranged in array. The scan lines provide driving voltages to the sub pixel units, and the data lines provide data voltages to the sub pixel units, and the common electrode lines provide common voltages to the sub pixel units. The common voltage compensation circuit comprises a feedback signal processor, an amplifier and a common voltage adjusting circuit, and the feedback signal processor is connected to the common electrode lines to obtain feedback signals of the common voltages, and the amplifier implements an amplifying process to the feedback signals after inversion to obtain compensation signals, and the common voltage adjusting circuit inputs the compensation signals to the common electrode lines.
