Abstract: A method of generating information to control display of images providing a display device with align pattern data to which box data having a maximum reference gray level is added, obtaining a first capture image generated based on the align pattern data to which the box data is added, providing the display device with one or more full pattern data respectively having one or more reference gray levels lower than the maximum reference gray level, and obtaining one or more second capture images generated based on the one or more full pattern data. The method also includes generating compensation data including compensation values at the one or more reference gray levels and the maximum reference gray level. The compensation data may be generated based on the one or more second capture images and a portion of the first capture image corresponding to the box data.

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.

Abstract: An electronic device is disclosed that includes a display panel, a data driving circuit, a scan driving circuit, and a driving controller. The driving controller generates image data based on a received image signal. The driving controller includes a minimum emission gray level determining unit that determines a gray level of the image signal, a pattern determining unit that determines a dither pattern of the image signal, a driving frequency sensing unit that determines a driving frequency of the image signal, and a data compensation unit that compensates for the image data based on the gray level and at least one of the dither pattern and the driving frequency.
