Classification: CPC G | IPC G

Claim 0:
1. A display device, comprising:
a display panel including a plurality of pixel rows;
a power supply configured to provide a power voltage to the display panel; and
an overcurrent protector configured to shutdown the power supply when at least one of the pixel rows is burnt, the overcurrent protector including:
a sensing controller configured to sense a first current of at least one first pixel row of the display panel in a first frame period, and configured to sense 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; and
a burnt determiner configured to determine whether the first pixel row is burnt, and configured to provide a shutdown signal to the power supply when the first pixel row is burnt,

wherein the sensing controller is configured to sense a third current of at least one second pixel row of the display panel adjacent to the first pixel row in a third frame period after the second frame period when the second current is greater than or equal to the first threshold value, and
wherein the burnt determiner is configured to determine that the first pixel row is burnt when the third current is greater than or equal to a second threshold value.
