Abstract: A display device includes first pixels partitioned into a plurality of blocks, each of the plurality of blocks being categorized as a first block or a second block, a sensor configured to generate first sensing data for at least two of the first pixels in each of the plurality of blocks during a first period, and a sensing controller configured to generate interpolated data for the first pixels that are not sensed by the sensor by interpolating the first sensing data, for the first block, and configured to forgo interpolation of the first sensing data, for the second block. The sensor generates second sensing data for the first pixels that are not sensed by the sensor, for the second block, during a second period after the first period.

Abstract: A display device includes a display unit including a plurality of pixels and a sensing unit disposed outside the display unit, where the sensing unit senses deterioration information of a driving transistor in each of the pixels through a plurality of sensing lines, and compensates for deterioration of the driving transistor. the sensing unit senses the deterioration information during a first sensing period, and the first sensing period is included in each of a power-off period in which power for the display device to display an image is not supplied, a power-on period in which the display device is turned on, and an image display period in which the image is continuously displayed after the display device is turned on.

Abstract: A display device includes a display unit, a scan driver, and a data driver. The display unit includes pixels coupled to scan lines, sensing scan lines, data lines, and sensing lines. The scan driver supplies a scan signal to the scan lines, and supplies a sensing scan signal to the sensing scan lines. The data driver supplies an image data voltage to the data lines, and detects sensing values of the pixels on a pixel column basis through the sensing lines during a sensing period. The data driver includes an analog-to-digital converter which converts the detected sensing values into digital data during the sensing period and outputs sensing data. The analog-to-digital converter pauses the detection of the sensing values during a first period of the sensing period.

Abstract: An organic light-emitting display device includes a plurality of pixels, each of which is connected to a scan line, a data line, a first power line and a second power line, and includes a light-emitting diode. A voltage applied to an anode of the light-emitting diode is higher than a voltage applied to a cathode in a first operation period, and a voltage applied to the anode of the light-emitting diode is lower than a voltage applied to the cathode in at least a part of a second operation period different from the first operation period.

Abstract: An organic light emitting display and a method for driving the same are presented. The display and the method enable display of images at a substantially constant luminance level over time, even when degradation of the organic light emitting diode occurs. Components are used to compensate for the degradation of an organic light emitting diode and a difference in the threshold voltage/mobility of a driving transistor.
