Abstract

A liquid crystal display panel comprises a gate drive, a source drive, multiple gate lines (202) and multiple data lines (203). The multiple gate lines (202) and the multiple data lines (203) define multiple pixel units (201). Each pixel unit (201) comprises a thin film transistor, a common electrode (2012) and a pixel electrode (2013). The data line (203) is used for charging the pixel electrode (2012). The liquid crystal display panel further comprises a common electrode line (204). The common electrode line (204) is connected to the common electrode (2014), and is used for providing an alternating common electrode voltage to the common electrode (2014), so that when a gate voltage of the thin film transistor is turned off, a voltage value of the pixel electrode (2013) is still close to a target voltage value of the pixel electrode (2013) when being charged by the data line (203). Also provided is a voltage control method of a liquid crystal display panel.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a voltage control method thereof. 【Background technique】 [0002] With the continuous development of liquid crystal display technology, users have higher and higher requirements on the quality of liquid crystal display. [0003] see figure 1 , figure 1 It is a driving circuit diagram of a liquid crystal display (Liquid Crystal Display, LCD) panel in the prior art, including a pixel electrode 101 , a gate line 102 , a data line 103 , a pixel capacitor 104 and a storage capacitor 105 . [0004] After the gate voltage (not shown) of the thin film transistor (Thin Film Transistor, TFT) is turned on, an electrical signal is written into the pixel electrode 101 by the data line 103 , giving the pixel electrode 101 a voltage signal to be filled. Afterwards, the gate voltage of the thin film transistor is turned off, and the pixel el...
