Shift register unit, shift register and driving method, array substrate

Abstract

The present invention provides a shift register unit, a shift register, a driving method, and an array substrate, which are used to realize the touch control of the display panel without affecting the normal display of the display panel, thereby improving the display effect of the display panel. The shift register unit includes a touch activation module and a touch deactivation module. The control end of the touch activation module is connected to the touch activation signal, the input end of the touch activation module is connected to the negative signal of the power supply, and the output end of the touch activation module is connected to the touch activation signal. The output terminal, the touch start signal is a pulse signal in the touch time period; the control end of the touch off module is connected to the touch off signal, the input end of the touch off module is connected to the positive signal of the power supply, and the output end of the touch start module The output terminal is connected, and the touch off signal is a pulse signal at the end of the touch time period.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display driving, in particular to a shift register unit, a shift register and a driving method, and an array substrate. Background technique [0002] The shift register (Gate Drive on Array, GOA) integrates the gate drive (Gatedriver) of the LCD Panel on the glass substrate to form a scan drive for the display panel. Compared with the traditional COF and COG processes, it not only saves costs, but also the Panel can achieve a symmetrical and beautiful design on both sides, and also saves the Bonding area of ​​​​the Gate IC and the Fan-out wiring space to achieve a narrow border design; at the same time, due to The process of Bonding in the Gate direction can be omitted, which is also beneficial to the improvement of production capacity and yield. Based on the above advantages, GOA design has been more and more used in the current tablet design. Touch screens mainly include resistive, capa...

AI Technical Summary

Problems solved by technology

[0003] Embedded touch screens are divided into self-capacitance and mutual-capacitance. The touch drive electrodes need to be driven in time division to realize the touch function and display function. In order to ensure the touch effect, the display time needs to be compressed, which will generate Affected, poor display occurs

[0004] The TDDI embedded touch screen in the prior art starts the touch time after the display time is over, and continues the previous display time after the touch function ends, so in the prior art, the display time is mainly shortened, and the touch The control time is interspersed in the display time, which will affect the display and cause poor display.
