Abstract

The invention discloses a shift temporary storage circuit and a display device. The shift temporary storage circuit comprises a multiple stages of shift temporary storage units, wherein the shift temporary storage units are arranged in a cascading manner and comprise charging modules, a pre-charging signal input end of one charging module is electrically connected with a pull-up point of the frontstage of the shift temporary storage unit, and when the pull-up point of the shift temporary storage unit is pre-charged, and a pull-up signal of the pull-up point of the front stage of the shift temporary storage unit is in a high-level state. According to the technical scheme, the pre-charging time required in a shift temporary storage circuit is shortened, and the waveform of a scanning signalis optimized, so that the display effect of the display device is improved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a shift register circuit and a display device. Background technique

[0002] In order to adapt to the development of thinner, thinner frame and lower cost of display devices, Gate Drive on Array (GOA) is usually used to realize the output of line scanning signals at present. The integration is realized on the array substrate of the display device. The shift temporary storage circuit includes cascaded multi-stage shift temporary storage units, and each level of shift temporary storage units is precharged under the action of the scanning signal output by the previous stage of the shift temporary storage unit. However, due to the limited size of the high level of the scan signal output by the previous shift register unit, the precharge time required by the shift register unit at this stage is often longer and the precharge is insufficient, and the waveform of the generated scan si...
