Abstract
A burning protection circuit of a display device includes a plurality of current measuring units and a control unit. The display device includes a plurality of pixel blocks. Each of the pixel blocks includes a plurality of pixels. The pixel blocks are respectively supplied with power through a plurality of power supply lines. The current measuring units are configured to respectively generate a plurality of measured current values by respectively measuring a plurality of currents respectively supplied to the pixel blocks through the power supply lines. The control unit is configured to respectively generate a plurality of block data for the pixel blocks based on pixel data for the pixels of corresponding ones of the pixel blocks, and determine whether an overcurrent occurs based on a plurality of ratios of the measured current values to corresponding ones of the block data.
