ABSTRACT:
A field emission display (FED) and a driving method thereof. The FED of the present invention sequentially applies a selection signal to second electrodes through a scan driver, a data signal to a first group of first electrodes through a first data driver, and a data signal to a second group of the first electrodes through a second data driver. In this way, data lines are divided into data lines in the upper side of the screen and data lines in the lower side of the screen and are then separately driven, thereby preventing a non-uniform brightness of the upper and lower sides of the screen caused by a resistance component of the data lines.
