Abstract:
1. 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, the gate lines receiving one of a scanning pulse and a turn-off signal; an electro-luminescence cell, a driving thin film transistor, a switching thin film transistor, a storage capacitor and a bias switch provided for each of the pixels, for the pixel connected to an n a gate driver that sequentially applies the scanning pulse and the turn-off signal to the gate lines to sequentially drive the gate lines in the order of an (n−2) a data driver that applies an analog data signal synchronized with the scan pulse to the data lines, wherein the bias switch for the pixel connected to the nth gate line (GLn) includes: a drain terminal connected to the gate terminal of the driving thin film transistor for the pixel connected to the n a source terminal connected to the (n−1) a gate terminal connected to the (n−2) wherein a first switching thin film transistor is connected to the (n−2)
