Abstract

The disclosure relates to a shift register unit, a driving method of the shift register unit, a gate drive circuit and a display panel, and relates to the field of display technology. The shift register unit includes: an input module, a pull-up module, a storage capacitor, and an output module, configured to transmit the first voltage signal to a signal output terminal under the control of the first voltage signal; an output control module configured to Under the control of the voltage signal of the pull-up node and the first selection signal, the first voltage signal or the second power supply signal is transmitted to the signal output terminal, and, under the control of the voltage signal of the pull-up node and the second selection signal Next, the first voltage signal or the second power signal is transmitted to the signal output terminal. The present disclosure can improve detection accuracy.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a shift register unit, a driving method for the shift register unit, a gate drive circuit and a display panel thereof. Background technique [0002] With the development of optical technology and semiconductor technology, flat panel displays represented by liquid crystal display (Liquid Crystal Display, LCD) and organic light emitting diode display (Organic Light Emitting Diode, OLED) have the advantages of light and thin, low energy consumption, fast response speed, color The characteristics of good purity and high contrast ratio occupy a dominant position in the display field. [0003] In recent years, display devices have shown a development trend of high integration and low cost. Represented by Gate Driver on Array (GOA) technology, GOA technology is used to integrate the gate driver circuit in the peripheral area of ​​the array substrate, thereby effectively i...
