Abstract: A display device may include a display panel including a plurality of pixel rows, a power supply providing a power voltage to the display panel, and an overcurrent protector shutting down the power supply when at least one of the pixel rows is burnt. The overcurrent protector may include a sensing controller sensing a first current of at least one first pixel row of the display panel in a first frame period, and sensing a second current of the first pixel row in a second frame period after the first frame period when the first current is greater than or equal to a first threshold value. The overcurrent protector may further include a burnt determiner determining whether the first pixel row is burnt, and providing a shutdown signal to the power supply when the first pixel row is burnt.

Abstract: In a display device, each of pixels includes a light emitting element and a pixel circuit which is connected to the light emitting element at a first node and drives the light emitting element in response to a corresponding driving scan signal among driving scan signals during a display period. The pixel circuit is connected to a corresponding readout line among readout lines at a second node. The sensing circuit senses a potential of the first node through the corresponding readout line during a blank period, and each of frames includes the display period and the blank period. At least two driving scan signals among the driving scan signals respectively include a plurality of rewriting periods, each of which is activated during the blank period corresponding thereto, and the rewriting periods of the driving scan signals have different durations from each other.

Abstract: A display device includes a data driver providing a data voltage to each of multiple pixels, a scan driver providing first and second scan signals to each of the pixels, and a controller to control the data driver and the scan driver. The scan driver performs a first active scan operation that sequentially provides the first and second scan signals to the pixels in an active period of a first frame period, and initiates a dummy scan operation that sequentially provides the second scan signal to the pixels in a blank period of the first frame period. When a second frame period starts before the dummy scan operation for the pixel in a last row, the data driver changes a level of the data voltage in an overlap period in which the dummy scan operation and a second active scan operation in the second frame period are simultaneously performed.
