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.

The data line intersects the pixel electrode, and the pixel electrode includes an opening corresponding to a portion of the data line. The opening has a horizontal width that is wider or narrower than the horizontal width of the data line. Thereby, parasitic capacitance that occurs between the data line and the pixel electrode is reduced to improve image quality.

摘要： 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.

摘要： A liquid crystal display according to an embodiment of the present invention provides a OCB liquid crystal display that can stably operate without breaking the bending alignment regardless of applied voltage. The display includes first and second alignment layers that are formed on the first and second substrates, respectively, and that horizontally align the liquid crystal layer. 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. A bending alignment is obtained without experiencing asymmetric splay alignment by creating an energy difference between the energy needed for the alignment to transition to the twist alignment adjacent to the upper alignment layer and the energy needed for the alignment to transition to the twist alignment adjacent to the lower alignment layer.

摘要： In a display apparatus, a first display substrate includes a common electrode to which a common voltage is applied. A second display substrate facing the first display substrate includes a first pixel electrode and a second pixel electrode. The first and second pixel electrodes formed in one pixel region are spaced apart from and insulated from each other. A first data voltage having a first polarity with reference to the common voltage is applied to the first pixel electrode, and a second data voltage having a second polarity different from the first polarity with reference to the common voltage is applied to the second pixel electrode. Thus, a fringe field is formed between the first and second display substrates and a lateral field is formed in the second display substrate, thereby improving a transmittance and a response speed of the display apparatus.
