Abstract
Disclosed are driving circuit and method which are used in an Organic Light Emitting Diode (OLED), and more specifically to a driving circuit of an organic light emitting diode and a driving method thereof which use a thin film transistor (TFT) as an active device. The driving circuit and method can uniformly produce luminance of the light emitting element because the driving current is produced by compensating the unevenness of threshold voltage of the active device. Further, the variance of the threshold voltage Vdue to deterioration of the transistor produced according as the driving circuit of the OLED is utilized for a long time is also compensated, thereby increasing life of the display device which applies the driving circuit of the OLED.
