Abstract: A driving controller of a display device includes: an accumulation unit, which outputs accumulation data, which is obtained by accumulating a deterioration state, and a deterioration stress value based on an input image signal and a deterioration prediction temperature value; a temperature prediction unit that calculates the deterioration prediction temperature value based on the accumulation data, a color acceleration coefficient, a color current contribution ratio, and a temperature signal; and a compensation unit that outputs an output image signal based on the input image signal and the deterioration stress value.

Abstract: A display driver includes a nonvolatile memory, an encoder, a decoder, and a compensator. The nonvolatile memory is configured to store accumulated stress data and compensation data corresponding to the accumulated stress data. The encoder is configured to encode the compensation data received from the nonvolatile memory to generate encoded compensation data. The decoder is configured to decode the encoded compensation data to generate decoded compensation data. The compensator is configured to process input image data based on the decoded compensation data and generate accumulated stress data.
