Abstract
An electron emission panel driving method and apparatus that is capable of reducing the panel's power consumption. The driving method includes the operation of comparing two successive frames of image data. When the two successive frames are not identical, each of the two frames is driven during a one-frame period, and when the two successive frames are identical, only one frame is driven during a two-frame period.
Claims14
A method of driving an electron emission panel including pixels defined at regions where scan electrodes and data electrodes cross each other, where input gradation data displayed on each pixel is formed using input image signals and the pixels are driven according to the input gradation data, the method comprising:
- comparing two successive frames;
- driving each of the two successive frames during a one-frame period when the two successive frames are not identical;
- and
- driving only one frame of the two successive frames during a two-frame period when the two successive frames are identical.
An apparatus for driving an electron emission panel including pixels at regions where scan electrodes and data electrodes cross each other, comprising:
- an image processor to generate image data;
- a frame comparing unit to compare two successive frames of the image data;
- a logic controller to generate a scan signal and a data signal based on the comparison result of the frame comparing unit;
- a scan driving unit to drive the scan electrodes according to the scan signal;
- and
- a data driving unit to drive the data electrodes according to the data signal,
- wherein the logic controller generates the scan signal and the data signal to drive each of the two successive frames during a one-frame period when the two successive frames are not identical, and the logic controller generates the scan signal and the data signal to drive only one frame of the two successive frames during a two-frame period when the two successive frames are identical.
