Patent ID: 8284124

Claim:
An organic electroluminescent display device, comprising: pixels each including: an organic light-emitting diode; a first transistor outputting a data voltage according to an nth scan signal (n is a natural number); a second transistor providing a current to the organic light-emitting diode according to the data voltage; and a capacitor storing the data voltage; and a third transistor directly supplying the second transistors and the capacitors of the pixels connected to an nth scan line with a pre-charge voltage according to an (n−1)th scan signal, the pre-charge voltage having an opposite polarity to the data voltage, wherein a source electrode of the third transistor is connected to an nth scan line providing the nth scan signal to the first transistor, wherein a signal of the nth scan line consists of a high level voltage and a low level voltage, wherein the nth scan line provides the first transistor with the high level voltage as the nth scan signal, and wherein the third transistor provides the second transistors and the capacitors of the pixels connected to the nth scan line with the low level voltage as the pre-charge voltage.
