Display apparatus

A display apparatus, comprising:

• a display panel including a plurality of split regions defined by dividing a screen;
• a data driving portion including a plurality of driving portions respectively corresponding to the plurality of split regions;
• a gamma voltage portion configured to provide a same gamma voltage set to the plurality of driving portions;
• and
• a data processing portion including a data adjustment portion and a maximum dimming signal extraction portion,
• wherein the data adjustment portion processes a plurality of input image data respectively corresponding to the plurality of split regions to output a plurality of output image data to the plurality of driving portions,
• wherein the maximum dimming signal extraction portion provides a maximum dimming signal among a plurality of dimming signals that respectively set luminances of the plurality of split regions to the gamma voltage portion, and
• wherein the data adjustment portion converts a luminance gain of each of the plurality of split regions obtained based on the maximum dimming signal into a data gain, and applies each data gain to one of the plurality of input image data.
