Patent ID: 7605543

Claim:
An electro-luminescence display device comprising: an electro-luminescence panel having a plurality of pixels at pixel areas defined by intersections between data lines and gate lines, each of the pixels including: an electro-luminescence cell connected to receive a supply voltage; a driving thin film transistor controlling a current amount flowing through the electro-luminescence cell; and a bias switch connected to a gate terminal of the driving thin film transistor, the bias switch selectively applying an inverse voltage to the gate terminal of the driving thin film transistor, wherein the bias switch comprises, a drain terminal connected to the gate terminal of the driving thin film transistor of the pixel connected to an n th gate line (GLn, n being an integer); a source terminal connected to an inverse voltage source, the inverse voltage source supplying the inverse voltage; and a gate terminal connected to an (n-1) th gate line (GLn-1).
