Abstract: An electronic device includes a main processor that provides an image signal and an image-sticking correction signal, and a display module that receives the image signal and the image-sticking correction signal and outputs an image data signal obtained by compensating for the image signal. The display module includes a compensation circuit that calculates cumulative stress based on the image data signal and outputs an image-sticking compensation signal and a compensation adjuster that outputs the image data signal obtained by correcting the image signal based on the image-sticking correction signal and the image-sticking compensation signal. The image-sticking correction signal is input by a user manipulation.

Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The driving controller generates a data signal based on input image data. The data driver converts the data signal into a data voltage and outputs the data voltage to the display panel. The driving controller includes a deterioration compensator. The deterioration compensator generates an alpha value based on a ratio between a sensed current read from a portion of the display panel applied with a high power voltage or a portion of the display panel applied with a low power voltage and a predicted current calculated from the input image data and generates the data signal using the input image data, a stress value of a pixel, and the alpha value.
