Problems solved by technology

Therefore, the power consumption of the electron emission display device (or light emitting display device) is increased
[0015] In addition, when an image with low luminance is displayed, the luminance of the display portion 10 decreases, thereby deteriorating the contrast ratio.

Abstract

An electron emission display device for reducing or preventing non-uniformity in color from being generated due to a difference in brightness characteristics of red, blue, and green light components, and a method of driving the same. The display device includes: red, blue, and green pixels adapted to emit light in accordance with data signals and scan signals applying a voltage to first and second electrodes; a data driver adapted to receive image signals to generate the data signals and to transmit the data signals to the display portion; and a color controlling unit adapted to control a voltage of the first electrodes to correspond to the image signals and to correct the image signals to correspond to emission rates of the red, blue, and green pixels in accordance with a change in the voltage of the first electrodes so that the corrected image signals are transmitted to the data driver.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2005-0086542 filed with the Korean Intellectual Property Office on September 15, 2005, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to an electron emission display device and a method of driving the same, and more particularly, the present invention relates to an electron emission display device and a method of driving the electron emission display device capable of Reduce or prevent color non-uniformity generated in the process of controlling gate voltage and cathode voltage. Background technique [0003] In general, electron emission devices used in electron emission display devices can be classified into electron emission devices using hot cathode rays as electron sources and electron emission devices using cold cathode rays as electron sources. Electron emissi...
