  • Patent number: 8072473
    Abstract: 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.
