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.

摘要: 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.
