DISPLAY DEVICE AND A DRIVING METHOD THEREOF, CAPABLE OF DETECTING THE AMOUNT OF COMPENSATION USING THE AMOUNT OF BRIGHTNESS REDUCTION CORRESPONDING TO THE RESISTANCE OF AN ORGANIC LIGHT-EMITTING DEVICE

摘要

PURPOSE: A display device and a driving method thereof are provided to compensate image data by calculating the amount of compensation according to accumulated light time.;CONSTITUTION: A display unit(100) comprises a plurality of pixels. The plural pixels are connected to a scan line and a plurality data lines respectively and radiates light according to the image data. A dummy pixel is connected to a dummy scan and a dummy data line. A compensation image generator(500) calculates compensation amount according to the laminated lighting time of the first organic light emitting device. The compensation image data generator compensates image data corresponding to compensation amount.;COPYRIGHT KIPO 2012
