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: An electronic apparatus has a through module hole defined in an active area and includes a first sensing pattern and a second sensing pattern spaced apart from each other in one direction with the module hole disposed therebetween. A third sensing pattern and a fourth sensing pattern are spaced apart from each other in a direction crossing the one direction with the module hole disposed therebetween. A first connection line extends along a portion of the module hole and connects the first sensing pattern and the second sensing pattern to each other. A second connection line extends along a portion of the module hole and connects the third sensing pattern and the fourth sensing pattern to each other. The first connection line and the second connection line are disposed on the same layer and are spaced apart from each other.

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.
