Display driver integrated circuit and display device including the same

Abstract

A display driver integrated circuit includes a first memory, a compensator, a sampler and a data processor. The first memory stores accumulated stress data. The compensator generates an output data for image display by compensating an input image data based on the accumulated stress data. The sampler selects a slice data. The data processor generates a present slice accumulated data of a present slice accumulated data set by summing the selected slice data with a previous slice accumulated data of a previous slice accumulated data set, selects a maximum value 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 and 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.
