Electron emission display device and driving method thereof

摘要

An electron emission display device including: a pixel area for emitting electrons depending on voltage applied to a first electrode and a second electrode; a timing controller for outputting varying pulse widths clocks, the pulse widths of clocks being varied depending on gray scales of image signals. The display device also includes a data driver for generating data signals using the image signals and transferring them to the first electrode; a scan driver generating scan signals and transferring them to the second electrode; and a voltage controller for controlling the voltage of the second electrode depending on the sum of the image signals in one frame interval, wherein the data driver counts the number of the clock pulses to control the pulse widths of the data signals.
