Abstract: A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.

Abstract: A display device and method is provided that permits selection of a first lookup table or a second lookup table to operate the data driver at respectively different temperatures to prevent heat from damaging the display device. The display device includes a detector which detects the number of toggles in which the amount of change in gray values of successive pixels driven by the same data line in one frame is equal to or greater than a reference gray change amount. A comparator compares the number of toggles detected by the detector with a reference number of toggles, and a lookup table selector which selects any one of a first lookup table and a second lookup table based on the comparison result of the comparator and provides the selected first lookup table or second lookup table to a data driver.
