Abstract: A display device includes a signal controller and a data driving circuit. The data driving circuit includes a plurality of driving chips. At least one of the driving chips monitors a degree of distortion of a data signal. The at least one of the driving chips generates a feedback signal based on the monitored result to compensate for the distorted data signal.

Abstract: A display device includes a first block, which has a first first-color pixel set and a first second-color pixel set, and a second block, which has a second first-color pixel set and a second second-color pixel set. A cardinality of the first first-color pixel set plus a cardinality of the first second-color pixel set is unequal to a cardinality of the second first-color pixel set plus a cardinality of the second second-color pixel set. The display device includes a data driver for generating a first data voltage and a second data voltage based on a first curve and a second curve, respectively, and for providing the first data voltage and the second data voltage to the first block and the second block, respectively. A brightness value associated with the first curve is unequal to a brightness value associated with the second curve with respect to a same grayscale level.
