The invention provides an organic LED drive circuit, an array substrate and a display device. The organic LED drive circuit comprises multiple drive thin film transistors and multiple compensation thin film transistors for compensating the threshold voltage of a drive thin film transistor; every compensation thin film transistor corresponds to one drive thin film transistor; the source electrode of the compensation thin film transistor is connected with a compensation signal line, and the drain electrode is connected with the drain electrode of the corresponding drive thin film transistor; multiple compensation thin film transistors are divided into multiple groups, and each group comprises at least two compensation thin film transistors which share a gate electrode and a drain electrode and are connected with one same compensation signal line. The circuit is used for solving the problem of poor compensation effect in an existing drive circuit caused by slow charging rate or undercharge.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting diode driving circuit, an array substrate and a display device. Background technique [0002] In recent years, AMOLED (Active Organic Light Emitting Diode) display devices have gradually expanded in the market. Its ultra-high contrast, ultra-thin thickness, ultra-wide color gamut, good viewing experience with large viewing angles, ultra-fast response speed, and Features such as super large curvature and deflection make AMOLED display devices have great potential and market future. [0003] The AMOLED display device includes an organic light emitting diode array substrate, and the organic light emitting diode array substrate further includes organic light emitting diodes and driving thin film transistors (TFTs) for driving the organic light emitting diodes. The threshold voltage (Vth) of the driving thin film transistors is prone to drift, especi...
