摘要： A gray scale voltage generator and a method of generating a gray scale voltage in a transmissive and reflective type liquid crystal display device are disclosed. A transmissive mode gray scale data are transformed into real reflective mode gray scale data. An integer part is extracted from the real reflective mode gray scale data as a first reflective mode gray scale data. The first reflective mode gray scale data and temporary reflective mode gray scale data are mixed in a predetermined ratio by N-frame period. The temporary reflective mode gray scale data has a sum of one and the first reflective mode gray scale data. Pseudo gray scale data are inserted into the second reflective mode gray scale data. Therefore, superior display quality is provided in both transmissive and reflective mode.

摘要： A method of improving the viewing angle of a vertically-aligned liquid crystal display device is presented. The method involves designing a uniaxial compensation film to provide a retardation value of 200 nm or less for light having a wavelength of about 550 nm. Using this uniaxial compensation film, a display device can be built by obtaining a liquid crystal panel with liquid crystal molecules contained between glass substrates, coupling the uniaxial compensation film to at least one of the glass substrates, and coupling a polarization film and electrodes to the compensation film. Preferably, the uniaxial compensation film has a thickness less than or equal to 50 microns. Where there are multiple compensation films, the total thickness and the total retardation values should be considered.
