Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] The transistors used in all embodiments of the present invention may be triodes, thin film transistors or field effect transistors or other devices with the same characteristics. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the control pole, one pole is called the first pole, and the other pole is called the second pole.

[0062] In actual operation, when the transistor is a triode, the contr...

Abstract

The invention provides a driving circuit, a driving method and a display device. The driving circuit comprises a first control circuit, a second control circuit, an energy storage circuit, a first output circuit and a second output circuit; the first control circuit controls the potential of a first node according to an input driving signal provided by an input driving signal end; the second control circuit controls the connection between the first node and a first voltage end under the control of a control clock signal; the first output circuit controls an output driving signal end to be communicated with the first clock signal end under the control of the potential of the first node; the second output circuit controls the output driving signal end to provide an output driving signal according to the first clock signal. According to the invention, the problem that an existing driving circuit adopts a large number of transistors and is not beneficial to realizing a narrow frame is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving circuit, a driving method and a display device. Background technique [0002] In the related technology, LTPO (Low Temperature Polycrystalline Oxide, low temperature polycrystalline oxide) pixel circuit can use LTPS (low temperature polysilicon) P-type TFT (thin film transistor) and IGZO (Indium GalliumZinc Oxide, indium gallium zinc oxide, indium gallium zinc oxide) N-type TFT It is constructed by using a low-level effective driving signal to control the P-type TFT, using a high-level effective driving signal to control the N-type TFT, and adding a light-emitting control signal, three sets of signal generation circuits are required. The number of transistors is large, and it needs to occupy a large border. Contents of the invention [0003] The main purpose of the present invention is to provide a driving circuit, a driving method and a display device, whic...
