Abstract
A driving apparatus, and a driving method for an electron emission display, includes a controller for comparing external video data input signals, switching a polarity control signal in a predetermined period on the basis of the comparison and controlling a video data output signal in accordance with the polarity control signal, and a data driver for modulating the video data signal output from the controller. The switching of the polarity control signal may be shifted temporally when the comparison indicates the video data input signals have the same gray level.

A driving apparatus for an electron emission display, comprising:
- a controller for comparing external video data input signals, switching a polarity control signal in a predetermined period on the basis of the comparison and controlling a video data output signal in accordance with the polarity control signal;
- and
- a data driver for modulating the video data signal output from the controller.
A method of driving an electron emission display, comprising:
- receiving a video data signal in response to a horizontal synchronous signal;
- switching a polarity control signal in accordance with a blanking signal of the horizontal synchronous signal;
- comparing video data signals received corresponding to two lines;
- switching the polarity control signal on the basis of the comparison;
- and
- selectively inverting the video data signal on the basis of the polarity control signal.
