Abstract: An organic light-emitting display includes: a display panel, scan and data drivers, an ADC, a controller, and a data switch. In a first initialization period, the data switch connects data lines to the data driver, which applies an initialization voltage thereto. In a first sensing period, the data switch connects the data lines to the ADC. The ADC receives analog sensing signals corresponding to first voltages of the data lines, and converts the analog sensing signals into digital sensing signals output to the controller. In a second initialization period, the data switch connects the data lines to the data driver, which applies the initialization voltage thereto. In a second sensing period, voltages at the data lines change to second voltages, the data switch connects the ADC to the data lines, and the ADC converts analog sensing signals corresponding to the second voltages into digital sensing signals output to the controller.

Abstract: A display device includes a display unit, a degradation compensator and a data driver. The display unit includes first and second pixels disposed in first and second regions, respectively. The degradation compensator generates a first compensated grayscale value by compensating a first grayscale value for the first pixel based on a first degradation curve and generates a second compensated grayscale value by compensating a second grayscale value for the second pixel based on a second degradation curve, where the first and second degradation curves define luminance reduction rates according to accumulated usage time of the first and second pixels, respectively. A data driver generates first and second data signals based on the first and second compensated grayscale values, respectively, and supplies the first and second data signals to the first and second pixels, respectively. A transmittance of the second region is greater than a transmittance of the first region.
