DISPLAY DEVICE AND ELECTRONIC DEVICE HAVING THE SAME

摘要

A display device includes: a display panel including a plurality of pixels; a power voltage generator to generate a high power voltage that is provided to the pixels through a high power line; a degradation compensator to calculate a degradation degree of the pixels by measuring a power current flowing through the high power voltage line, and to calculate a compensation amount of a degradation of the pixels based on the degradation degree of the pixels and image data provided to the pixels; a scan driver to provide scan signals to the pixels; a data driver to provide data signals to the pixels; and a timing controller to generate control signals to control the power voltage generator, the degradation compensator, the scan driver, and the data driver.
