Abstract: A display device includes a display panel including a pixel including a first sub-pixel displaying a first color, a second sub-pixel displaying a second color, and a third sub-pixel displaying a third color, a data driver applying a data voltage generated based on input image data to the pixel in an active period, sensing the first sub-pixel to generate first sensing data in a blank period, sensing the second sub-pixel to generate second sensing data in the blank period, and sensing the third sub-pixel to generate third sensing data in the blank period, and a driving controller compensating for the first sensing data, the second sensing data, and the third sensing data based on a grayscale value of the input image data.

Abstract: An organic light-emitting display apparatus includes a display area including first and second pixels. A plurality of photo sensors is arranged in an outer area of the display area. The first pixel includes a first pixel electrode, an opposite electrode, and a first emission layer between the first pixel electrode and the opposite electrode. The first pixel electrode, the opposite electrode, and the first emission layer are arranged on a substrate. The second pixel includes a second pixel electrode, the opposite electrode having a reflectance less than a reflectance of the second pixel electrode, and a second emission layer between the second pixel electrode and the opposite electrode. The second pixel is closer to the plurality of photo sensors than the first pixel. The second pixel electrode includes a first portion in parallel with the substrate and a second portion having a slope with respect to the substrate.
