Patent ID: 11682340

Abstract:
A sub-pixel circuit, and an active electroluminescence display and a driving method thereof are provided. The sub-pixel circuit includes at least one electroluminescence device, and at least one first driving transistor or at least one second driving transistor and at least one third driving transistor coupled with the at least one electroluminescence device. A cathode of the electroluminescence device is coupled with a power source, an anode of the electroluminescence device is coupled with an output terminal of the first driving transistor, an input terminal of the first driving transistor is coupled with a signal line, and a control terminal of the first driving transistor is coupled with a scan line. Alternatively, the anode of the electroluminescence device is coupled with an output terminal of the second driving transistor, an input terminal of the second driving transistor is coupled with an output terminal of the third driving transistor.
