Organic light emitting display and method of correcting images thereof

摘要

An organic light emitting display and a method of correcting images thereof prevents the occurrence of excessive pixel aging, burning and image sticking caused by loading effect and includes: a loading effect measuring unit to measure a luminance according to a level at which an image signal having an equal gray scale value is loaded into a display panel of the organic light emitting display; an average loading level calculating unit to calculate a loading level at which the luminance averages; a loading effect compensating unit to compensate the power supply voltage corresponding to the image signal to obtain a luminance equal to the luminance at the average loading level; and a power supply control unit to control the power supply voltage to supply the compensated power supply voltage to the display panel of the organic light emitting display.
