Problems solved by technology

Taking the 127-gray-scale pixel as an example, since the average value of the positive and negative polarity driving voltage of the 127-gray-scale pixel cannot be guaranteed to be exactly the same as VCOM (reference voltage), so the 127-gray-scale pixel is under positive or negative polarity driving voltage. When it is inconsistent with the absolute value of the voltage difference of VCOM, the brightness of the pixels with the same gray level is inconsistent under the positive and negative polarity driving voltage.

Abstract

The invention provides a liquid crystal panel driving method and driving device. The driving method comprises the following steps of A, determining the current reverse rotation driving mode of a liquid crystal panel; B, performing preset operation on the gray value of all pixels of an image to be displayed of the liquid crystal panel; C, when the result value of the preset operation is greater than the preset value, changing the current reverse rotation driving mode. According to the embodiment, the flickering problem when the liquid crystal panel statically displays the image can be solved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal displays, and more specifically relates to a driving method and a driving device of a liquid crystal panel. Background technique [0002] Due to the characteristics of the liquid crystal molecules themselves, when a pure DC voltage is used to drive the deflection of the liquid crystal molecules in the liquid crystal display (LCD), it is easy to induce the polarized molecules in the liquid crystal material to generate a polar electric field, resulting in the existence of a constant DC bias voltage. , and then cause the image sticking phenomenon. For this phenomenon, the industry usually adopts an inversion driving method in which positive and negative polarities are reversed to improve it. However, when the liquid crystal panel is driven by a fixed inversion driving method, when the liquid crystal panel displays certain images statically, the brightness changes constantly, resulting in flic...
