Abstract: A display device includes: a plurality of pixels at a display area around a transmissive area; a first crack detection pattern at the transmissive area; a 2-1st crack detection pattern on the first crack detection pattern; and a 2-2nd crack detection pattern on the first crack detection pattern, the 2-2nd crack detection pattern being spaced from the 2-1st crack detection pattern, and adjacent to the 2-1st crack detection pattern. In a plan view, the first crack detection pattern overlaps with the 2-1st and 2-2nd crack detection patterns.

Abstract: A display device includes a protective film, a display panel, and a conductive film package. The protective film has a first area, a second area, and a third area positioned between the first area and the second area. The display panel is disposed in the first area and the third area on the protective film. The conductive film package is disposed on the display panel, and is in contact with the protective film positioned in the second area. In this manner, a defect of the substrate included in the display panel and a defective adhesion between the conductive film package and the display panel may be avoided.

Abstract: An organic light-emitting diode (OLED) display and a method of driving the same are disclosed. In one aspect, the OLED display includes a display panel including a plurality of pixels and a plurality of sensing regions. The OLED display further includes a temperature sensor array comprising a plurality of temperature sensors respectively arranged on the sensing regions. The OLED display also includes a controller configured to output a plurality of control signals so as to sequentially select the temperature sensors, receive a plurality of output signals output from the temperature sensors selected by the control signals, and generate first temperature data corresponding to the locations of the selected temperature sensors based on the output signals.
