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.
