Abstract

The invention provides a liquid crystal display panel, a pixel capacitance residual charge driving circuit and a method thereof. The method comprises steps that a display control signal is inputted to the liquid crystal display panel, and the display control signal is used for controlling normal frame display of the liquid crystal display panel; a voltage of the liquid crystal display panel is controlled for boosting to a pre-determined value; a grid line is controlled for scanning display pixels of the liquid crystal display panel, and the liquid crystal display panel is controlled for displaying monochromatic frames. Compared with the prior art, the method is advantaged in that through control of an LCD Driver, display pixel capacitance residual charges of the liquid crystal display panel are released, a liquid crystal polarization problem is solved, no extra resource is occupied through the method, normal operation of the liquid crystal display panel is not influenced, detection through the LCD Driver is not required, and the method is further advantaged in that the method is simple and efficient, and normal display of the liquid crystal display panel is not influenced.

Description

technical field [0001] The present invention relates to the technical field of a liquid crystal display panel driving circuit and method, in particular to a liquid crystal display panel, a pixel capacitor residual charge driving circuit and a method thereof. Background technique [0002] If there is residual charge in the display pixel capacitor of the LCD panel, the liquid crystal is prone to polarization. After polarization, there will be afterimages of black lines or screen flickering, which will make the LCD panel unable to display and work normally. [0003] The existing method to solve the liquid crystal polarization of the liquid crystal display panel is generally to cut off the power of the liquid crystal display panel for a period of time, and then use it after the residual charge is slowly discharged by itself, which affects normal use. [0004] In addition, there is also a method of detecting the LCD Driver (driving circuit) to discharge the residual charge of the...
