Abstract

The application discloses a GOA circuit, its display panel, and a display device. The GOA circuit includes a GOA unit and a multiplexing control module connected to the GOA unit; the multiplexing control module includes a multiplexer and a hierarchical switch unit , a potential coupling unit, a pull-down unit and a pull-down control unit; the input end of the classification switch is connected to the output end of the GOA unit, and each control end is connected to each control output end in one-to-one correspondence; the potential coupling unit is connected to the output end of the GOA unit and the classification Between the input terminals of the switch unit; the pull-down unit is connected to each output terminal of the graded switch unit; the pull-down control unit is connected between the pull-down unit and the output terminal of the GOA unit, and the control signal is output through the multiplexer to realize the control of the GOA unit graded output. In the present application, the multiplexer is used to control the grading switch unit to perform grading output of the GOA unit, thereby fully charging multiple sub-pixels, and pulling down the potential of the GOA unit, thereby enhancing the stability of the circuit operation.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a GOA circuit, a display panel, and a display device thereof. Background technique [0002] GOA (Gate Driver On Array, array substrate line drive) is a technology that uses the existing thin-film transistor liquid crystal display Array process to manufacture the Gate line scan drive signal circuit on the Array substrate to realize the gate progressive scan drive method. . At present, when the GOA circuit is driven in stages, the charging of the sub-pixels is insufficient, and the circuit stability is poor. [0003] In the process of implementation, the inventors found at least the following problems in the traditional technology: when the current GOA circuit is driven in stages, the charging of the sub-pixels is insufficient, and the circuit stability is poor. Contents of the invention [0004] Based on this, it is necessary to provide an overdrive method ...
