Abstract: A field emission display apparatus including a field emission display panel and a driving device for the field emission display panel. The driving device includes a power supply unit, the power supply unit including an abnormal current detection unit and a discharge circuit. The abnormal current detection unit generates an arc-current detection signal when the value of a current flowing between a negative anode voltage terminal of the field emission display panel and a common ground line is larger than an upper limit. The discharge circuit generates a short circuit between an anode plate of the field emission display panel and the negative anode voltage terminal when the arc-current detection signal is generated from the abnormal current detection unit.

Abstract: An electron emission display device and a driving method thereof are disclosed. The device and method limit a brightness thereof in order to reduce power consumption, and adjust a gamma compensation according to a limit width of the brightness to reduce a gamma compensation deviation, causing an increase in a quality of an image. In a pixel portion, a brightness is controlled corresponding to applied voltages of a first electrode and a second electrode and an emission time. An image signal summing section receives and sums image signals by frame periods. A gamma selector selects a gamma based on an output signal of the image signal summing section and compensates for the image signals. A data driver converts the compensated image signals to generate a data signal, and transfers the data signal to the first electrode. A scan driver generates and transfers a scan signal to the second electrode.

Abstract: A method of driving an EED device can prevent the luminance from being degraded due to the delay of the display data signals applied to the electrode lines.
