Abstract
The invention provides a flat display device which comprises for pixels arranged along drive lines a voltage drop calculator 27 for calculating a voltage drop occurring in accordance with the position of each pixel, and a video signal converter 30 and a lookup table 31 for correcting the input signal to be supplied to the pixel in accordance with the magnitude of the calculated voltage drop, whereby crosstalk due to the voltage drop is prevented.
Claims8
A flat display device wherein a pair of electrodes are arranged respectively on opposite sides of a luminescent layer, and a voltage in accordance with an input signal is applied across the electrodes by a drive signal supplied through a drive line for each of pixels provided by the luminescent layer to cause the luminescent layer to luminesce,
- wherein the display device comprises:
- means provided for the drive line for calculating a voltage drop occurring in the drive line based on the magnitude of current flowing through the pixel in accordance with the input signal to be supplied to the pixel and on a resistance value depending on the position of the pixel, and
- means for correcting the input signal to be supplied to the pixel based on the magnitude of the calculated voltage drop.
