Abstract: A display device according to an embodiment includes switches. Low and high voltages of a selection control signal applied to each of gate electrodes of the switches are varied according to whether one of positive and negative data voltages is applied to each of the source electrodes of the switches. As such, the swing width of the selection control signal can be maintained regardless of the positive and negative data voltages. In accordance therewith, undesired power consumption can be prevented.

Abstract: A method for driving an electro-luminescence display device is provided. The method includes selecting a scan line by applying a scan signal to any one of a plurality of scan lines, wherein the scan signal falls down to a voltage higher than a ground voltage; and applying a constant voltage to a plurality of data lines crossing the scan lines in synchronization with the scan signal.

Abstract: This invention relates to a method for driving an electro-luminescence display device. The method includes the steps of selecting a scan line by applying a scan signal to any one of a plurality of scan lines; and switching between a constant voltage and a constant current to apply data to a plurality of data lines crossing the scan lines. The method switches between the constant voltage source and the constant current source to drive the data lines. As a result, it increases the brightness uniformity and brightness. Therefore, the picture quality can be sustained at a high level.
