摘要： 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.

摘要： A method of processing data in a display device for displaying an image is disclosed. In one aspect, the method includes: dividing the data elements of an image data into sections based on the distribution of the data elements; then generating a header for each section; compressing each data element to a compressed data element by using an offset specific to the section including the data element, an interval of the section including the data element and the header for that section; and generating an image data signal for displaying the image using the compressed data element.
