A
display device (100), comprising: a display panel (110) which is divided into a plurality of active areas (AA); a data driver (130) configured to supply data voltages to a plurality of pixels (PX) arranged in each of the plurality of active areas (AA); and a timing control device (140) configured to output a
power control signal (PWRC) for controlling a driver current for the data driver (130), wherein the plurality of active areas (AA) is divided into central active areas (CA), in which a plurality of pixel columns are arranged on a central section of a plurality of pixel columns that are arranged in each of the plurality of active areas (AA), and into active periphery areas (EA), in which a plurality of pixel columns are arranged on an outer section of a plurality of pixel columns that are arranged in each of the plurality of active areas (AA), the data driver (130) contains a plurality of integrated source driver circuits (SDICs), each of which is configured to supply at least one of the data voltages to one of the plurality of active areas (AA), and the timing control device (140) is configured to generate the
power control signal (PWRC) as a function of a difference value (DV) between comparison data (CD), which is a maximum data transition value between adjacent pixel rows arranged in each of the multiple active areas (AA), and edge comparison data (ECD), which is the maximum data transition value between adjacent pixel rows arranged in the multiple
active edge areas (EA), wherein the
time control device (140) has: a
data release signal generator (141) configured to generate a sub-
data release signal (SDE) configured to determine an output timing of a data
voltage supplied to each of the multiple active areas (AA), and a
boundary data release signal (EDE) configured to determine an output timing of a data
voltage supplied to each of the multiple active boundary areas (EA); a
data delay unit (142) configured to
delay video data (data) by one horizontal period and output the delayed video data (D_data); a data comparison unit (143) configured to compare the video data (data) and the delayed video data (D_data) and to generate the comparison data (CD) and the edge comparison data (ECD); and a
power control signal generator (144) which is configured to generate the power
control signal (PWRC) using the reference data (CD) and the boundary reference data (ECD). wherein the power
control signal generator (144) is configured to set a first reference value (SV1) by applying the comparison data (CD) to a first
lookup table, set a second reference value (SV2) by applying the boundary comparison data (ECD) to a second
lookup table, set a compensation value (CV) by applying a difference value (DV) between a first reference value (SV1) corresponding to an active area (AA) and a second reference value (SV2) corresponding to an active boundary area (EA) adjacent to the active area (AA) to a third
lookup table, and add the compensation value (CV) to the first reference value (SV1) corresponding to the active area (AA) and output a result as the power
control signal (PWRC).
