Abstract

A driving device comprises an nth-stage circuit and an (n + 1) th-stage circuit. The nth-stage circuit is used for deciding whether to provide a first voltage stabilizing signal, a second voltage stabilizing signal or a third voltage stabilizing signal according to the first selection signal or the second selection signal, and deciding whether to provide a first grid signal according to the first voltage stabilizing signal or the second voltage stabilizing signal. The (n + 1) th-stage circuit is used for determining whether to provide a lower-stage first voltage stabilizing signal, a lower-stage second voltage stabilizing signal or a lower-stage third voltage stabilizing signal according to the first selection signal or the second selection signal, and is used for determining whether to output a lower-stage second grid signal according to the lower-stage first voltage stabilizing signal and the lower-stage third voltage stabilizing signal.

Description

technical field [0001] This case is related to a display device, and in particular to a gate driving device applied to an organic light emitting diode display. Background technique [0002] The Organic Light-Emitting Diode (OLED) display has the advantages of high contrast, high color saturation and good luminous efficiency, making it one of the hot technologies of the next generation. The traditional gate drive device needs to have forward or reverse transmission function, and its internal node leakage current will affect the output, and if the thin film transistor in the circuit is aging, the threshold voltage (Threshold voltage, Vth) variation will affect the output. Therefore, how to provide OLED driving devices and displays with high display quality is a technical problem to be solved in the industry. Contents of the invention [0003] This Summary is intended to provide a simplified summary of the disclosure in order to provide the reader with a basic understanding ...
