发明名称 Circuit and method for driving organic light emitting diode
摘要 A drive circuit for organic light emitting diodes (OLEDs), and a method for driving OLEDs, using the drive circuit. The drive circuit includes pixel circuits, each of which includes a first transistor for receiving a data voltage, and outputting a drive current to an OLED, a second transistor for transmitting the data voltage to the first transistor, a third transistor for connecting the gate and drain of the first transistor, a capacitor for storing a gate voltage of the first transistor, and a fourth transistor connected to the drain of the first transistor. The OLED is connected to the source of the first transistor by a fifth transistor, or is directly connected to the source of the first transistor without using the fifth transistor. The drive circuit generates drive current, based on a non-uniformity-compensated threshold voltage of the first transistor, thereby obtaining a uniform luminance of the OLED.
