Abstract: A sensor includes: a hole; a sensing area formed around the hole, wherein at least one sensor is in the sensing area; and a crack detector configured to output a first crack signal if a comparison value obtained by comparing a detected value from the at least one sensor with a reference value exceeds an error range.

Abstract: A device for correcting gamma set data includes a memory, voltage calculator, and a corrector. The memory stores high gamma set data including first register values set per grayscale and low gamma set data including second register values set per grayscale and reference register value. The voltage calculator calculates a reference voltage value of the low gamma set data based on the reference register value and calculates fixed voltage values per grayscale of the low gamma set data based on the second register values. The corrector compares the first register values with the second register values and corrects the second register values based on a comparison result.

Abstract: A display device includes: a display panel including a pixel electrically connected to each of a data line, a first power line, a second power line, and a third power line; a power supply to provide a first power voltage to the first power line, and a second power voltage to the second power line; and a driver to provide a data voltage to the data line, and a third power voltage to the third power line. The driver is to determine whether a sensing voltage measured at the second power line is out of a reference range, and to limit the supply of the third power voltage when the sensing voltage is out of the reference range.
