Problems solved by technology

It can be seen from the above formula that no matter how small the resistance value of M2 is designed, when CLKB and the input signal terminal Input input high level to the inverting circuit at the same time, the voltage value V of the output signal terminal Output out Neither can drop to VGL, so the output signal of the above-mentioned inverter will be affected by the characteristics of the field-effect thin film transistor (English: Thin Film Transistor, referred to as: TFT), and the output signal will be unstable.

Abstract

The embodiments of the invention provide an inverter, a driving method thereof, a GOA (Gate driver On Array) unit, a GOA circuit and a display device and belong to the technical field of display. The inverter is used for supplying stable inverter output signals. The inverter comprises a control module and an output module, wherein the control module is used for controlling the voltage of a control node under the control of first clock signals of a first clock signal terminal, second clock signals of a second clock signal terminal, input signals of an input signal terminal, voltage of a first electric level terminal and voltage of a second electric level terminal; the output module is used for leveling voltage of an output signal terminal and the voltage of the first electric level terminal or the voltage of the second electric level terminal under the control of the control node and the input signals of the input signal terminal. The embodiments of the invention are applied to the manufacturing of displays.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an inverter (English: Inverter) and a driving method, an integrated gate driver (English: Gate driver On Array, GOA for short) unit, a GOA circuit and a display device. Background technique [0002] The inverter (English: Inverter) has an inverting effect on the signal input to it, that is, the output signal of the inverter and the input signal are mutually inverting signals. With the development of electronic technology, the application of inverters is becoming more and more extensive. For example, inverters can be used in the emission drive circuit of organic light-emitting display devices to provide corresponding potentials for the pixel compensation circuit electrically connected to the emission drive circuit. In order to enable the pixel compensation circuit to complete node initialization, threshold compensation and data writing, etc. [0003] refer to figure 1 a...
