Abstract
A display device includes a substrate, a plurality of gate lines disposed on the substrate, and which extends in first direction, a plurality of data lines disposed on the substrate, and which extends in a second direction intersecting the first direction, pixels connected to the gate lines and the data lines, a data drive unit which applies data signals to the data lines, a gate drive unit which supplies gate signals to the gate lines, a timing controller which controls the data signals and the gate signals, an image depth analysis unit which receives an image signal, and generates a foreground image signal based on an image depth of the image signal, and a gamma correction unit which generates a gamma-corrected image signal by applying a plurality of gamma curves to the foreground image signal.
