Abstract: In a optically compensated bend (OCB) liquid crystal display, an impulsive voltage is applied to a pixel between applications of normal data voltages for displaying an image, and the impulsive voltage and the normal data voltage are controlled to prevent breaking of the bending alignment of the (OCB) liquid crystals. Accordingly, luminance of the liquid crystal display can be improved. When the normal data voltage of 0V is applied, the impulsive voltage at which the bending alignment of OCB liquid crystal is broken is set to the impulsive voltage at (for, corresponding to) the highest gray. There occurs a broken region (0-VB) where the bending alignment of the OCB liquid crystal is broken at a predetermined range that is higher than 0V. A voltage that is higher than the highest voltage (VB) of the broken region is set to a white voltage. Accordingly, luminance of the OCB liquid crystal display can be enhanced.

Abstract: An OCB (Optically Compensated Bend) liquid crystal display in which impulse driving is performed such that an impulse data voltage is applied between normal data voltages used for displaying an image. The impulse data voltage is divided into a first impulse data voltage and a second impulse data voltage having a voltage value that will not break a bent alignment of the OCB liquid crystals. Referring to the application of the first impulse data voltage between the normal data voltages as first impulse driving and the application of the second impulse data voltage between the normal data voltages as second impulse driving, the second impulse driving is performed at every two or more of the first impulse drivings, so as to not break the bent alignment of the liquid crystals and to thereby improve luminance of the LCD.

A normal data voltage is determined based on a first gamma curve representing luminance corresponding to external image information and impulsive data voltages are determined based on a second gamma curve representing a luminance that is lower than that of the first gamma curve. The normal data voltage and the impulsive data voltage are applied periodically and alternately.
