Abstract: A radio communication terminal includes a novel lighting control mechanism for selectively changing a lighting part in the radio communication terminal during a suitable time for a detected operating communication mode. The lighting part is flexibly changed in consideration of the detected operating communication mode to reduce total power consumption of the radio communication terminal. For example, if a moving picture communication mode is detected, the lighting control mechanism lights the display, but not the key operating unit, and if a voice call mode is detected, both the display and the key operating unit are not lighted. Further the lighting control mechanism can include a brightness control unit for controlling the brightness of the selected lighting suitable for a detected operating communication mode.
