Abstract

The invention provides a voltage holding circuit and a driving method, a GOA (Gate on Array) unit and circuit, and a display panel, relates to the technical field of display, and is used for solving the problem that the node voltage may not be held in the prior art. The voltage holding circuit comprises a first control unit, a second control unit and an output unit, wherein the first control unit is used for leveling the voltage of a first node and a first level terminal or leveling the voltage of the first node and a second level terminal under the control of voltage of a voltage holding node, and the second control unit is used for leveling the voltage of a second node and the first level terminal or leveling the voltage of the second node and the second level terminal under the control of control signals input by a control signal input terminal and the voltage of the first node; the output unit is used for inputting the voltage of the first level terminal to the voltage holding node under the control of voltage of the second node. The invention is used for producing the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a voltage holding circuit and a driving method, a GOA unit and circuit, and a display panel. Background technique [0002] Thin Film Transistor Liquid Crystal Display (full English: Thin Film Transistor Liquid Crystal Display, referred to as: TFT-LCD) has been widely used in monitors, mobile phones, digital cameras, electronic photo frames and other electronic products. In order to further realize human-computer interaction and improve user experience, a touch display panel is also proposed in the prior art, and an in-cell touch display panel (English full name: In Cell Touch) integrates touch panel functions and display functions in One body, specific advantages such as thinness, low cost, etc., is the mainstream development direction of the embedded touch display panel. [0003] Usually, the in-cell touch display panel is driven in a time-sharing driving manner. Specifically...
