If the brightness level is an LCD back light off level, the CPU outputs an LCD back light off controlling signal to a back light controller. The LCD back light is turned off. If the brightness level corresponds to 'weak', the CPU outputs a 'weak' brightness level controlling signal to the back light controller. The LCD back light is lighted up with 'weak' level brightness. If the brightness level corresponds to 'medium', the CPU outputs a 'medium' brightness level controlling signal to the back light controller. The LCD back light is lighted up with 'medium' level brightness. If the brightness level corresponds to 'strong', the CPU outputs a 'strong' brightness level controlling signal.
