Abstract: An integration driver includes a plurality of stages. Each of the plurality of stages includes a scan signal generator including first to third nodes and a fifth node and an emission control signal generator including a fourth node and sixth node. The scan signal generator is configured to generate a first signal provided to a first node, a second signal provided to a second node, and a third signal provided to a third node using a first clock signal, a second clock signal, and a start signal or a carry signal, and generate a scan signal using the second signal and the third signal. The emission control signal generator is configured to generate a fourth signal provided to a fourth node using the third signal and the second clock signal, and generate an emission control signal using the first signal and the fourth signal.

Abstract: A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.
