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 substrate including a display area at a front surface and a non-display area at a periphery of the display area, wherein the non-display area includes a bending area having at least a portion bent toward a rear surface; a first metal layer on the substrate, the first metal layer overlapping with a contact hole at an out side of the bending area in the non-display area; a first via layer as an organic layer, located over the first metal layer, the first via layer including the contact hole; a second metal layer on the first via layer, the second metal layer being electrically connected to the first metal layer in the contact hole; and an inorganic layer on the second metal layer, wherein at least a portion of one side end of the inorganic layer, which is in the non-display area, is at an outside of the bending area and an area on the contact hole.

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.

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.
