Abstract
A circuit for driving an organic light-emitting diode (OLED) in a thinfilm transistor electroluminescent (TFT-EL) display at least includes the first and the second transistors. Wherein, a data line and a capacitor are respectively connected to the source and drain electrodes of the first transistor. The capacitor is charged from the data line by turning on the first transistor. And, the capacitor and an OLED are respectively connected to the source and drain electrodes of the second transistor. The capacitor is discharged by turning on the second transistor, and results in light emitting of the OLED.
