Problems solved by technology

In the display scanning stage, the touch screen uses the GOA circuit to drive the corresponding pixel blocks and then enters the touch scanning stage, which can improve the sensitivity of touch control, but will increase the risk of failure of the GOA circuit
This is because during the touch scanning phase, the GOA circuit will suspend the scan driving of the gate lines, thereby increasing the risk of gate leakage of the thin film transistors connected to the gate lines

Abstract

The invention provides a grid electrode driver. The grid electrode driver comprises multiple stages of driving units (210). Each stage of the driving unit (210) comprises a GOA driving circuit (211) and multiple stages of buffering GOA driving circuits (212). The GOA driving circuits (211) are used for outputting and inputting signals during a display stage. The output signals are transmitted to grid electrode lines and the multiple stages of the buffering GOA driving circuits (212). The multiple stages of buffering GOA driving circuits (212) carry out stage transmission on the output signals during a touch control stage and transmit the output signals to the GOA driving circuit (211) of next stage of the driving unit (210). The invention also provides a touch control panel with the grid electrode driver. According to the invention, the multiple stages of buffering GOA driving circuits (212) are used for transmitting the output signals in a staging manner during the touch control stage, thereby preventing the output signals from being cut off during the touch control stage, and further reducing electric leakage risks of switch devices like thin-film transistors connected with the grid electrode lines.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a gate driver and a touch panel with the gate driver. Background technique [0002] At present, the more common capacitive touch screens usually adopt three technologies: OGS (One Glass Solution, that is, integrated touch), On-Cell (plug-in type) and In-Cell (embedded type). Among them, the capacitive touch screen using In-Cell technology has the advantages of thinner, thinner, better light transmission and more stable structure compared with the capacitive touch screen using OGS technology and On-Cell technology due to its advantages in manufacturing process. [0003] In a capacitive touch screen using In-Cell technology, a liquid crystal panel or an OLED display panel is generally used as a display screen. Taking a liquid crystal panel as an example, a Gate Driver On Array (GOA) technology is usually used to manufacture a gate driver on an array substrate, so as t...
