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.

Abstract: A display apparatus includes an image data receiver receiving image data of an image to be displayed. A driving mode determining controller receives anomalous trichromat data of a user, determines a driving mode as either a general driving mode or an anomalous trichromat correction driving mode, and outputs a driving mode signal indicative of the determination. A correction mode requirement luminance calculator calculates a correction mode requirement luminance for an image output for the user. A backlight boosting determination controller determines a level of boosting light emitted from a backlight, and outputs a boosting determine signal. An image data converter converts image data corresponding to the anomalous trichromat data of the user and the correction mode requirement luminance, and outputs a data signal corresponding to correction image data. The backlight emits light having an intensity corresponding to signals. A pixel transmits light according to the data signal.
