Abstract

The present invention relates to a shift register unit and a driving method thereof, a gate drive circuit, and a display panel, and relates to the technical field of display. The shift register comprises: an input module; a pull-up module; a storage capacitor; an output module which is configured to transmit a first voltage signal to a signal output end under the control of the first voltage signal; and an output control module configured to transmit the first voltage signal or a second power supply signal to the signal output end under the control of a voltage signal and a first selection signal of a pull-up node, and transmit the first voltage signal or the second power supply signal to the signal output end under the control of the voltage signal and a second selection signal of the pull-up node. The detection precision can be improved.

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 of the shift register unit, a gate driving 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 (LCD) and Organic Light Emitting Diode (OLED) have 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 the Gate Driver on Array (GOA) technology, the GOA technology is used to integrate the gate drive circuit in the peripheral area of ​​the array substrate, thereby achieving a narrow frame design and effectively improving the integration of the display dev...
