Abstract

The application discloses a GOA circuit and a display panel. By adding a thin film transistor to the pull-down maintenance module, the pull-down maintenance module is electrically connected to the first node, the second node and the output terminal of the output module, and receives a constant voltage high level, which can pull up the level of the second node, Maintain the low level of the first node and the low level of the output terminal of the output module; and effectively reduce the thin film transistors and clock signals required by the forward and reverse scanning control module, and reduce the settings of global signals and corresponding thin film transistors, which is conducive to narrower display panels Implementation of borders.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a GOA circuit and a display panel. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD for short) has become the mainstream display on the market. Shown in different colors. Gate Driver On Array (GOA for short) technology is to use the existing thin film transistor liquid crystal display array (Array) process to manufacture the gate drive circuit on the array substrate of the liquid crystal display panel to realize the gate line (Gate ) A technology of progressive scanning driving mode. [0003] Please also refer to Figure 1A-Figure 1C ,in, Figure 1A is the circuit diagram of the existing GOA circuit, Figure 1B for Figure 1A The forward scanning driving timing diagram of the shown GOA circuit, Figure 1C for Figure 1A Timing diagram of the reverse scan driving of the shown GOA circuit. [0004] like Figure 1A As shown, the ...
