Abstract

The invention provides a device for eliminating remnant trace, a shift buffer unit, liquid crystal display equipment and a method. By only matching a delay discharge phenomenon of a high voltage source, which is generated by a power supply device in shutting off, the shift buffer unit is driven, any two signal sources in a plurality of signal sources form high quasi-bits so as to control a discharge switch module to charge and discharge pixel units. The invention not only can solve the problem of the remnant trace in shutting off, but also has the signal resetting function in startup.

Description

A Shift Register Unit for Eliminating Afterimages technical field The invention relates to a device, a shift register unit, a liquid crystal display device and a method for eliminating residual images, in particular to a shift register unit capable of eliminating shutdown residual images. Background technique Generally, a liquid crystal display (LCD) mostly uses a driving module (Driving Circuit) to control the generation of grayscale signals of multiple pixels (Pixel) on the panel of the liquid crystal display. The driving module mainly includes a gate driver (GateDriver) electrically connected to the number Scanning lines (or gate lines) to output gate pulse signals (GatePulseSignal) to each corresponding pixel, and a source driver (SourceDriver) electrically connected to several data lines (or source lines) to transmit The data signal (DataSignal) is sent to each corresponding pixel, and the intersection of each scanning line and each data line is also respectively conn...
