Problems solved by technology

[0003] However, under the long-term operation of the liquid crystal display, the liquid crystal ions will gradually approach the two ends of the capacitor and accumulate on the electric plate, resulting in the imbalance of the electric field and image sticking.
Due to the above-mentioned process differences, different electric field distributions may be generated at different positions on the LCD screen, causing residual images to randomly appear in different positions, so it is difficult to solve the residual image problem by adjusting the reference voltage level

Abstract

A driving method used in a liquid crystal display (LCD) is used for preventing or mitigating an image sticking occurring on a screen of the LCD. The driving method includes driving a data line outputted to a liquid crystal capacitor on the screen with a first voltage signal; and driving a reference voltage line outputted to the liquid crystal capacitor with a second voltage signal; wherein the second voltage signal and the first voltage signal have inverse voltage polarities.

Description

technical field [0001] The present invention relates to a driving method and system for a Liquid Crystal Display (LCD), in particular to a driving method and system capable of avoiding or slowing down image sticking on the LCD screen. Background technique [0002] A Liquid Crystal Display (LCD) is the most mature and widely used display among various flat panel displays on the market. In the manufacturing process of liquid crystal displays, liquid crystals will produce ionization errors due to process factors such as residence time between processes (Q-time), liquid crystal drop (liquid crystal drop), and directional rubbing (Polyimide rubbing). In order to solve the above-mentioned problems, a common practice in the industry is to output display data by interleaving positive and negative polarities (such as dot inversion, line inversion, or frame inversion). The liquid crystal ions can be evenly distributed in the electric field of the liquid crystal capacitor. [0003] H...
