Abstract: The present invention discloses a liquid crystal display and a driving method thereof to speed up a bend alignment at an initial operation such as right after power on in the liquid crystal display with OCB mode. According to the present invention, the LCD, which includes a LCD panel, a source driver outputting image signals and a gate driver sequentially outputting scanning signals, at an initial operation, is controlled to output externial bias voltages to common electrode lines and simultaneously to stop the driving of the gate driver and the source driver, according as a first time passes, is controlled to output specific common electrode voltages thereto instead of the external bias voltages and simultaneously to perform a driving of the source driver and the gate driver. As a result, at an initial operation, by applying high-level bias voltages instead of the common electrode voltages to the common electode lines and simultaneously stopping the driving of the gate driver, the source driver and a back light, the speed of the initial bend alignment of a liquid crystal with OCB mode can be made to be high.

Abstract: A liquid crystal display apparatus having a liquid crystal layer using OCB mode liquid crystal, in which a pixel electrode (622) to which an individual pixel voltage is applied with respect to each pixel and an opposed electrode (608) arranged opposite to the pixel electrodes are disposed, a non-voltage region (630) having no voltage to the opposed electrode is formed for each pixel in a region within the same face as the pixel electrode, and the size of the non-voltage region is such that even if the liquid crystal layer becomes bend orientation, at least a part of the region can maintain splay orientation.
The non-voltage region accelerates a transition of the liquid crystal layer in the pixel from bend orientation to splay orientation upon power-off.

Abstract: The present invention relates to a color display device, comprising at least two light sources (16, 17), having different radiance spectra, and a liquid crystal light valve layer (14). The light sources (16, 17) are activated sequentially and the light valve layer is provided with driving signals (d1, d2) in such a way that it obtains a strong wavelength dependence. This allows the display device to produce primary colors without the provision of color filters. This provides a less complex display, which is suitable for mobile applications and provides high brightness.
