Patent number: 8665193Abstract: 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.Type: GrantFiled: July 18, 2006Date of Patent: March 4, 2014Assignee: Samsung Display Co., Ltd.Inventors: Eun-Hee Han, Hee-Seop Kim, Jun-Young Lee, Chang-Hun Lee, Jun-Woo Lee, Sung-Wook Kang
