  • Patent number: 7400311
    Abstract: A response time accelerator and method for driving a liquid crystal display (LCD) are provided. According to the response time accelerator for driving an LCD, an acceleration unit reads previous data Pn?1 corresponding to input current data Pn from a frame memory unit that updates and stores one or more frames of previous data Pn?1. The acceleration unit then reads predetermined mapped panel output value TPO, predetermined mapped panel characteristic value TpPn, and flag information corresponding to the previous data Pn?1 and current data Pn from a table memory unit that stores predetermined mapped panel output values TPOs, predetermined mapped panel characteristic values TpPns, and flag information corresponding to the predetermined mapped panel characteristic values TpPns, and decodes the read information.

  • Patent number: 7102695
    Abstract: A method and apparatus for selectively enhancing contrast depending on the level of incoming video signals while preserving colors are provided. An apparatus for enhancing the contrast and brightness of a video signal displayed on a display device includes: a first luminance level transformation circuit that receives luminance and chrominance signals, reduces the level of the luminance signal in response to a first control signal, and outputs the chrominance signals and the luminance signal whose level has been reduced; an image converting circuit that receives the output signals from the first luminance level transformation circuit and converts the received signals into RGB video signals; and a second luminance level transformation circuit that receives the RGB video signals from the image converting circuit, concurrently increases the respective levels of the RGB video signals in response to a second control signal, and outputs the RGB video signals whose levels have been increased.
