Problems solved by technology

However, in order to ensure that the TFTs on the array substrate have a sufficient charging rate, the transistor device connected to the pull-up node inside the gate drive unit circuit (also called a shift register unit circuit) will be damaged due to characteristic drift due to excessive voltage. Poor display occurs, which affects the normal operation of the GOA circuit

Abstract

The invention provides a gate driving unit circuit, a gate driving circuit and a method for driving the gate driving unit circuit. The gate drive unit circuit includes an input sub-circuit and an output sub-circuit. The input sub-circuit is connected to a first pull-up node, a second pull-up node andan input end, and the input sub-circuit transmits signals input by the input end to the first pull-up node and the second pull-up node under the control of the signals input by the input end. The output sub-circuit is connected to the first pull-up node, the second pull-up node, a first control end, a third control end, a first output end and a second output end. The output sub-circuit transmits a signal input through the first control end to the first output end under the control of the potential of the first pull-up node, and transmits a signal input through the third control end to the second output end under the control of the potential of the second pull-up node.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a gate driving unit circuit, a driving method for the gate driving circuit, and a display device including the gate driving circuit. Background technique [0002] Gate Driver on Array (GOA) technology is a technology that directly manufactures a gate driver circuit (also called a shift register circuit) on an array substrate instead of a driver chip made from an external chip. The application of GOA technology can simplify the manufacturing process, reduce product costs, improve the integration of display panels, and make the panels thinner. A circuit integrated on an array substrate using the GOA technology is also called a GOA circuit. [0003] With the gradual development of displays with high resolution and high refresh rate, the charging rate of thin film transistors (ThinFilm Transistor, TFT) on the array substrate is required to be higher and higher. Howev...
