Abstract: A display device includes a display panel having pixels. A timing controller generates a first control signal and data control signals. Data driving circuits each recover a data signal from a corresponding data control signal of the data control signals in response to the first control signal, generate a data voltage corresponding to the data signal, and provide the data voltage to the display panel. Each of the data driving circuits includes: a setting unit configured to acquire a setting value from the data control signal; an equalizer configured to compensate for distortion of the corresponding data control signal according to the setting value to output compensated data control signal; and a recoverer configured to recover a clock signal from the compensated data control signal and recover the data signal from the compensated data control signal based on the clock signal.

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.
