A video display device is described, which is capable of easily correcting
variations in luminous brightness of each display element. When a video
display part is comprised of a plurality of display units including a
plurality of display elements, respective correction data for correcting
the variations in luminous brightness of the individual display elements
are supplied to memory means. When the display elements are driven, the
correction data is supplied to their corresponding drivers. In doing so,
the display elements can be driven in a corrected state of the variations
in luminous brightness. Even when a unit cell comprising display elements
is replaced by another and brightness level is re-adjusted, new correction
data relative to it is updated. Said updated correction data may simply be
stored in the same memory means. Thus, the variations in luminous
brightness can be easily corrected even when the unit cell is replaced by
another and re-adjusted.
