Abstract: A display device includes: pixels connected to corresponding scan lines, control lines, data lines, and sensing lines, a scan driver which supplies a scan signal to the scan lines, and supplies a control signal to the corresponding control lines, a data driver which supplies one of an image data signal and a sensing data signal to the corresponding data lines, and a sensing driver which senses characteristics of driving transistors of different pixels of the pixels in a previous sensing period and a current sensing period, and determines a final sensing value of a target pixel of the pixels in the current sensing period, based on a difference between a previous sensing value of the target pixel, which is determined based on the sensing in the previous sensing period, and a preliminary sensing value of the target pixel, which is calculated based on the sensing in the current sensing period.

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: An organic light-emitting display device may include a first pixel, a first data line, a first scan line, a data driver, and a scan driver. The first pixel unit may include a sensing transistor and a scan transistor. The data driver may be electrically connected to the scan transistor through the first data line. The scan driver may be electrically connected to the scan transistor through the first scan line. The scan transistor may be turned on during a first period and a second period. The sensing transistor may be turned on during a third period between the first period and the second period. The first period, the second period, and the third period are included in one frame.
