Abstract: An electron emission display for improving brightness uniformity by compensating brightness deviation between respective elements. The electron emission display includes a display panel, a scan driver, a data driver, and a brightness compensator. The display panel includes a plurality of scan electrodes, a plurality of data electrodes, and a plurality of display elements respectively formed at crossing points of the scan electrodes and the data electrodes. The display elements respectively include an electron emitter. The scan driver applies a selection signal to the scan electrode. The data driver applies a data signal to the data electrode. The brightness compensator compensates brightness by changing the data signal when brightness deviation of the display elements is greater than a predetermined threshold value.

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.
