Image display device

A drive circuit for displaying an image on a display panel by luminance of a plurality of pixels based on a video signal, comprising:

• a scan line control circuit, coupled to a plurality of scan lines of the display panel, that applies scan voltage to the scan lines;
• a signal line control circuit, coupled to a plurality of signal lines of the display panel, that applies drive voltage corresponding to the video signal to the signal lines;
• a correction circuit that corrects the drive voltage;
• wherein the correction circuit calculates a level for the correction of the drive voltage of N of the pixels (N≧1) such that a change of luminance at the N pixels is at or below a human allowable limit.

An image display device for displaying an image on a display panel based on a video signal, comprising:

• electron sources disposed at intersections between a plurality of first lines extended in a first direction of the display panel and a plurality of second lines of the display panel extending perpendicular to the first direction;
• and
• a voltage generation circuit that generates drive voltage according to the video signal and applies the drive voltage to the electron sources via the second lines,
• wherein when the video signal has a constant horizontal level, the voltage shows a pattern at electron sources along a first line, wherein the level is changed step-by-step from one end of the first line to the other end, and wherein a width of one stage of the stepwise pattern corresponds to a number from 3 to 99 times widths of the electron sources arranged in the first direction.
