/*! \defgroup G_LD Local dimming interface
    \ingroup  G_PERIPHERAL

    \brief

    Local dimming is introduced to achieve power saving and higher image contrast for LED backlight.


    <b>Features</b>

    - Less backlight, less energy
    - Compensation restores image luminance
    - Average 10~30% saving
    - Dark region becomes even darker
    - Light leakage problem

    <b> LD Block Diagram: </b> \n

    <b> Operation Code Flow: </b> \n
    -# mboot init, local dimming ready
    -# kernel run algorithm
    -# pm51 read led data from sharememory
    -# pm51 send luminance data to led via spi
