Display driver integrated circuit and display device including the same

An electronic device comprising:

• a display device comprising:
• a display panel including a plurality of pixels;
• and
• a display driver integrated circuit which drives the display panel, the display driver integrated circuit including:
• a first memory which stores accumulated stress data for compensating degradation of the plurality of pixels;
• a compensating circuit which generates an output data for image display by compensating an input image data based on the accumulated stress data;
• a sampling circuit which receives the input image data and selects a slice data by a unit of a slice, from each of a plurality of frames of the input image data based on a clock signal;
• and
• a data processing circuit which:
• receives the selected slice data from the sampling circuit;
• generates a present slice accumulated data of a present slice accumulated data set including degradation values of pixels and associated with a selected frame from the plurality of frames by summing the selected slice data with a previous slice stored in the first memory and accumulated data of a previous slice accumulated data set associated with the selected frame with the selected slice data,
• selects a maximum value from among the degradation values of the pixels included in the present slice accumulated data as a present maximum value;
• determines whether the present slice accumulated data is abnormal based on comparing a previous maximum value of the previous slice accumulated data set with the present maximum value;
• selectively updates the previous slice accumulated data set by selectively storing the present slice accumulated data set in the first memory based on the determination whether the present slice accumulated data is abnormal in a matter that at least a portion of the previous slice accumulated data set is updated with at least a portion of the present slice accumulated data set, and
• instructs the first memory to store the selectively updated previous slice accumulated data set as the accumulated stress data.
