Organic electroluminescent display, driving method and pixel circuit thereof |
摘要 |
Disclosed is an OELD and a pixel circuit which comprise: an organic EL element for emitting light corresponding to a supplied current; a first switch for switching data voltage supplied to a data line in response to a select signal supplied to a scan line; a first TFT for supplying the current to the organic EL element in response to the data voltage supplied to a gate of the first TFT via the first switch; a second TFT having a gate coupled to the gate of the first TFT and compensating for a deviation of a threshold voltage of the first TFT; and a capacitor for maintaining the data voltage supplied to the gate of the first TFT during a predetermined time.
