Claim Text:
1. A liquid crystal display panel, comprising a plurality of pixel units, each pixel unit comprising: a data line; a first scanning line; a second scanning line, adjacent to said first scanning line, and configured to transmit a preset scanning signal; a first switch, connected between said data line and a pixel electrode, and configured to be turned on when receives a scanning signal of said first scanning line; a second switch, connected between said pixel electrode and a common electrode, and configured to reach different turn-on states when receives the preset scanning signal of said second scanning line, said turn-on states comprising the state that the second switch is completely turned on and the state that the second switch is critically turned on for a certain time period, wherein said preset scanning signal includes a group of low-level voltages changing with a variation of data signal of said data line, and a high-level voltage being consistent with the scanning signal of said first scanning line; a storage capacitor, connected between said pixel electrode and said common electrode; and a liquid crystal capacitor, one end of which is connected to said pixel electrode, wherein when the first switch is turned on, said pixel electrode receives a data signal from said data line to have an electric potential; wherein during the process of said second switch being critically turned on for a certain time period, the electric potential of said pixel electrode decreases gradually through said second switch; and wherein at the moment when said second switch is completely turned on, the electric potential of said pixel electrode is changed instantaneously to a reference electric potential of said common electrode through said second switch.
