Abstract

The invention discloses a method for eliminating bright and dark lines of a liquid crystal display panel. The method comprises the following steps of: supplying an output enabling signal to a grid driver by using a time schedule controller, wherein the output enabling signal has a plurality of pulse wave widths; and transmitting a plurality of grid output signals to a plurality of blocks of the liquid crystal display panel through the grid driver respectively, wherein the plurality of grid output signals are defined by the plurality of pulse wave widths, wherein the plurality of grid output signals enable the charging time of pixels of the plurality of blocks to be equal. The method for eliminating the bright and dark lines of the liquid crystal display panel can eliminate the display defects such as the bright and dark lines caused by insufficient charging of the pixels of the liquid crystal display panel and the like.

Description

【Technical field】 [0001] The present invention relates to a method for eliminating bright and dark lines of a liquid crystal display panel, in particular to a control method for providing different widths of output enable (Output Enable, OE) signals for different blocks of a liquid crystal display panel to enable liquid crystal display The charging time of each block of the panel is equal to achieve the method of eliminating bright and dark lines. 【Background technique】 [0002] Liquid Crystal Display (LCD) has been widely used in computer LCD screens and LCD TVs in recent years due to its advantages such as low power consumption, thin and light weight, high resolution, high color saturation, and long life. Electronic products closely related to life. [0003] see Figure 1A , which shows a schematic structural diagram of a liquid crystal display panel of a thin film transistor liquid crystal display (TFT-LCD) in the prior art. A timing controller 101, through a plurality ...
