Abstract: A display device includes: a display panel, and a driving controller to receive an image signal and a control signal, drive the first display region of the display panel at a first driving frequency, and drive the second display region at a second driving frequency. The driving controller counts a first stress time of each of the first horizontal lines, and calculates a first operating time of each of the first horizontal lines based on the first stress time and the first driving frequency, counts a second stress time of each of the second horizontal lines and calculates a second operating time of each of the second horizontal lines based on the second stress time and the second driving frequency, and outputs an image data signal obtained by compensating for stress for the image signal based on the image signal, the first operating time, and the second operating time.

Abstract: A foldable display device is disclosed that includes a flexible display panel, an optical module, and a deterioration compensator. The flexible display panel includes a folding line, a first display area disposed on a first side of the folding line, and a second display area disposed on a second side of the folding line to display a test image. The optical module is disposed in the first display area and is configured to sense a display luminance of the test image. The deterioration compensator is configured to perform a deterioration compensating operation of the display luminance by a luminance compensation value when the display luminance is less than a target luminance, without performing the deterioration compensating operation when the display luminance is greater than the target luminance.

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.
