Abstract:
1. A pixel unit circuit comprising a first sub-circuit module, a second sub-circuit module, a first capacitor and an Organic Light-Emitting Diode (OLED) wherein an input of the first sub-circuit module is connected to a data line; another input of the first sub-circuit module is connected to an output of the second sub-circuit module and a first terminal of the OLED; an output of the first sub-circuit module is connected to an input/output of the second sub-circuit module via the first capacitor; and a voltage difference between positive power supply and negative power supply of a backboard is applied between an input of the second sub-circuit module and a second terminal of the OLED, wherein the first terminal of the OLED is an cathode of the OLED, and the second terminal of the OLED is an anode of the OLED the another input of the first sub-circuit module is connected to the cathode of the OLED, and the output of the first sub-circuit module ( the input of the second sub-circuit module is connected to ARVSS, the input/output of the second sub-circuit module is NG′ node and is connected to the other terminal of the first capacitor, the output of the second sub-circuit module ( the anode of the OLED is connected to ARVDD.
