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 processor including: an interface circuit to receive first image data and convert the first image data into second image data; a pattern detecting circuit to detect a pattern in the first or second image data; a brightness detecting circuit to detect a panel brightness value, and to detect a ratio of pixels emitting light; and a real-time sensing circuit, wherein when the pattern is not detected, the real-time sensing circuit performs/stops real-time sensing of the pixels based on whether the panel brightness value is within a range and the ratio of pixels emitting light is greater than or equal to a first threshold; and when the pattern is detected, the real-time sensing circuit performs/stops the real-time sensing of the pixels based on whether the panel brightness value is within the range and the ratio of pixels emitting light is greater than or equal to a second threshold.
