Problems solved by technology

However, for this solution, the switching elements T5 and T7 are turned on only when the second clock signal CLK2 is generated from a low potential to a high potential, and are not turned on when the second clock signal CLK2 is turned from a high potential to a low potential. There is a problem of signal instability, and capacitor C2 also increases the power consumption of the circuit

Abstract

The present invention proposes a gate driving circuit, which includes N-level gate driving units, and the nth-level gate driving unit includes first to seventh switching elements and a first capacitor. The gate driving unit receives the first clock signal to the fourth clock signal and a reference voltage. The invention also provides a display device. The gate drive circuit and the display device of the present invention enable the fifth switching element and the seventh switching element to be kept on in the stable stage through the setting of the fourth switching element, which ensures the stability of the control node and the gate scanning signal, and improves the The noise reduction ability is improved, the stability of the circuit is increased, and there is no need to set up multiple capacitors, thereby reducing power consumption, saving layout area, and increasing design space.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a gate driving circuit and a display device. Background technique [0002] Flat panel display devices such as liquid crystal display (Liquid Crystal Display, LCD) have many advantages such as thinness, energy saving, and no radiation, so they are widely used in electronic devices such as high-definition digital televisions, computers, personal digital assistants (PDAs), mobile phones, and digital cameras. in the device. [0003] Taking a thin film transistor (Thin Film Transistor, TFT) liquid crystal display device as an example, it includes: a liquid crystal display panel and a driving circuit, wherein the liquid crystal display panel includes a plurality of scanning lines and a plurality of data lines, and two adjacent scanning lines A pixel unit is formed by intersecting with two adjacent data lines, each pixel unit includes at least one thin film transistor, and the drive circuit include...
