Patent ID: 7863823

Claim:
A method of improving uniformity of brightness between a plurality of pixels in an electron emission panel comprising a plurality of scan electrodes extending in a first direction and a plurality of data electrodes extending in a second direction and intersecting the scan electrodes, wherein the plurality of pixels are defined at intersections of the scan electrodes and the data electrodes, the method comprising: respectively directly applying a scan driving voltage and a data driving voltage to a scan electrode and a data electrode of each of the pixels, wherein one of the scan driving voltage and the data driving voltage is higher than the other; measuring a brightness of each of the pixels; and respectively directly applying a scan adjustment voltage and a data adjustment voltage to the scan electrode and the data electrode of each of the pixels; wherein: one of the scan adjustment voltage and the data adjustment voltage is higher than the other; the scan adjustment voltage and the data adjustment voltage for each of the pixels correspond to the measured brightness of a respective one of the pixels; if the scan driving voltage is higher than the data driving voltage, the scan adjustment voltage is lower than the data adjustment voltage; and if the scan driving voltage is lower than the data driving voltage, the scan adjustment voltage is higher than the data adjustment voltage.
