Title:

PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, ARRAY SUBSTRATE AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/033014

Kind Code:

A1

Abstract:

A pixel circuit and driving method therefor, and corresponding array substrate and display device. The pixel circuit comprises: an inorganic electroluminescent device (10), a scanning terminal (Vsan), a data writing terminal (Vdata), a first level input terminal (V1), a second level input terminal (V2), a gating circuit (20), a driver circuit (30) and a storage circuit (40). A control terminal of the gating circuit (20) is connected to the scanning terminal (Vsan), an input terminal is connected to the data writing terminal (Vdata), and an output terminal is connected to a control terminal of the driver circuit (30). An input terminal of the driver circuit (30) is connected to the first level input terminal (V1), and the output terminal is connected to a first electrode of the inorganic electroluminescent device (10). In addition, the driver circuit (30) is used for supplying a corresponding drive current to the inorganic electroluminescent device (10) according to a data signal. Further, a second electrode of the inorganic electroluminescent device (10) is connected to the second level input terminal (V2). A first end of the storage circuit (40) is connected to the first level input terminal (V1), and a second end of the storage circuit (40) is connected to the control terminal of the driver circuit (30). The pixel circuit may improve display effect of an inorganic electroluminescent display device.
