Abstract: Provided is a display device including a pixel unit in which each of pixel rows extends in a first direction, odd numbered pixel rows and even numbered pixel rows are alternately disposed in a second direction, and pixels included in the pixel rows are designated as dots having two or more units, a gray difference calculator that calculates difference between representative grays of dots adjacent in the second direction among dots of a p-th pair of the pixel rows, an edge detector that increases an edge dot number when a first condition in which the difference between the representative grays is larger than a first threshold value is satisfied, and a first pattern detector that increases an edge number when the edge dot number is larger than a second threshold value, and that generates a first pattern detection signal when the edge number is larger than a third threshold value.

Abstract: A display device includes a first pixel including a first light emitter, a second pixel including a second light emitter, and a holding capacitor connected to the first and second pixels. The holding capacitor stores first data for the first light emitter and stores second data for the second light emitter at different times. An irradiation direction of first light emitted by the first OLED is substantially equal to an irradiation direction of second light emitted by the second OLED. The first light from the first OLED is emitted in a first frame period and the second light from the second OLED is emitted in a second frame period to prevent mixing of the first and second light.
