Abstract

The invention provides a shifting register unit, a grid drive circuit, a display device and a drive method. The shifting register unit comprises an input module, a reset module, an upward pull module, a downward pull control module and a downward pull module. The downward pull module comprises a tenth switch element used for enabling a first node and a first low level voltage wire to be controlled to be switched on, and a switch-off boost unit. The switch-off boost unit is used for stopping one end of the tenth switch element from being connected with the first low level voltage wire when the tenth switch element is in an off state. According to the shifting register unit, the grid drive circuit, the display device and the drive method, through the additionally-arranged switch-off boost unit, the switch-off function of the switch element in which electric leakage can happen is enhanced, PU point electric leakage is greatly reduced, and therefore the problem that touch scanning can cause concealed wiring display is solved.

Description

technical field

[0001] The invention relates to the field of touch screen display, in particular to a shift register unit, a gate drive circuit, a display device and a drive method. Background technique

[0002] At present, the touch screen display panel has become the mainstream mobile display terminal configuration, among which the capacitive touch screen CTP (Capacity Touch Panel) has absolute advantages in many aspects. In order to reduce the thickness of the box, the capacitive touch screen often adopts the method of integrating the In Cell (embedded) touch panel and the LCD panel, including Full In Cell (integrated embedded) and Hybrid In Cell (hybrid embedded). These two methods both involve the problem of time-sharing driving of signals in the touch scanning phase and display driving signals.

[0003] Taking Hybrid In Cell as an example, the method of time-sharing driving is to use the alternate scanning method of "display phase-touch scanning phase-display phase-to...
