Abstract:
An apparatus and method for driving an electro-luminescence panel wherein pixels in a current driving type electrode-luminescence panel are pre-charged to change a storage voltage of the pixel into the corresponding voltage within a limited scanning time. In the apparatus, a plurality of electro-luminescence cells are arranged at crossings between gate lines and data lines. A gate driver is connected to the gate lines to sequentially drive the gate lines. A data driver is connected to the data lines to apply pixel signals, via the data lines, to the electro-luminescence cells. A pre-charger is provided within the data driver to pre-charge a current into the data lines before the pixel signals are applied via the data lines.
