Abstract
An electro-luminescence panel that is adaptive for displaying a gray scale of picture. In the panel, a plurality of data lines are arranged in such a manner to cross a plurality of gate lines. electro-luminescence cells are provided at each intersection between the gate lines and the data lines. A cell driving circuit is provided at each of the electro-luminescence cells to respond to a signal at the data lines, thereby controlling a light quantity emitted from the electro-luminescence cells. A data driver supplies a voltage pixel signal to the data lines. A plurality of current drivers responds to the voltage pixel signal to control a current amount going through the data lines from the cell driving means.
