Abstract:
1. An electro-luminescence display device comprising: pixels provided between data lines and scan lines, each of the pixels including a light-emitting cell driven with a current; a current controller for temporarily increasing the current for subsequent driving of the light-emitting cell; a data driver to apply a data signal to the current controller; a light-emitting cell controller to control the current applied to the light-emitting cell; and a timing controller to apply the data signal to the data driver, and generating a first selection signal, a second selection signal, a third selection signal, a third selection signal, a fourth selection signal, a fifth selection signal, a sixth selection signal, a pre-charging selection signal and a pre-charging enable signal, wherein the current controller includes: a plurality of current sample holder portions connected to the data driver and the data line, and sampling the data signal from the data driver; and a plurality of pre-charging current suppliers connected between supply voltage lines and the data lines to apply a pre-charging current to the data lines.
