1. A liquid crystal display panel, comprising:
a first substrate comprising a plurality of data lines and a plurality of scan lines, and a plurality of pixel units defined by the data lines and the scan lines; a second substrate disposed to face the first substrate, and comprising a common electrode; and a driving circuit comprising:
a power module having a first input terminal, which is used for inputting an initial voltage to the common electrode; anda feedback unit having a second input terminal, a first output terminal, and a third input terminal used for inputting a DC voltage; wherein the second input terminal used for inputting an actual voltage at the common electrode; the first output terminal used for inputting a feedback voltage to the first input terminal;wherein when the actual voltage oat the common electrode is higher than the preset voltage, the feedback unit is used for lowering the voltage at the first output terminal and processing the input voltage at the second input terminal to output the feedback voltage via the first output terminal based upon the input voltage at the third input electrode, so that the actual voltage at the common electrode is equal to the preset voltage;wherein the first input terminal is connected with the common electrode, the first output terminal is connected with the first input terminal, and the second terminal is connected with the common electrode. |
