Problems solved by technology

[0004] However, because the GOA technology directly manufactures the gate drive circuit on the array substrate, the clock signal output from the timing control circuit TCON to the GOA unit is easily disturbed by static electricity, which will cause the LCD panel to scan the screen or display abnormally. Therefore, There is a need for an electrostatic protection method for GOA technology

Abstract

The invention discloses an electrostatic protection method, a device and a liquid crystal display. The electrostatic protection method comprises the following steps of monitoring the interface signal of a time sequence control circuit module and / or a level conversion module; judging whether the monitored signal is interfered by the electrostatic electricity or not; on the condition that the monitored signal is interfered by the electrostatic electricity, adjusting a time sequence control signal outputted by the time sequence control circuit module to an array substrate gate drive unit. The level conversion module is connected with the time sequence control circuit module and the array substrate gate drive unit, and is used for conducting the level conversion treatment on signals outputted by the time sequence control circuit module to the array substrate gate drive unit. According to the technical scheme of the invention, the electrostatic protection capability of the liquid crystal display adopting the row drive GOA technology of an array substrate is improved.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an electrostatic protection method, device and liquid crystal display. Background technique [0002] Gate Driver on Array (GOA for short) technology is a technology that directly manufactures gate driver ICs on an array substrate to replace a driver chip made of an external silicon chip. Such as figure 1 As shown, the GOA circuit can be directly produced around the panel, which reduces the production process, improves the integration of the liquid crystal panel (PANEL), and reduces the production cost. As modern display products have higher and higher requirements for ultra-narrow bezels, the market share of display products using GOA technology is increasing. [0003] The timing control circuit (Timing Controller, referred to as TCON) is the logic control core of the liquid crystal display circuit, responsible for controlling the timing action of the liquid crystal panel, c...
