Apparatus and method for controlling back light in mobile telecommunication terminal

摘要

An apparatus and method for controlling a back light in a mobile terminal is provided, in which a first back light of a liquid crystal display and a second back light of a key pad are independently controlled. The first and second back lights are driven if a flip cover is opened, while the first back light is only driven if the function selection key is input. Since the second back is not driven when the function selection key is input, unnecessary power consumption can be reduced.
