Method and system for controlling dual-processing of screen data in mobile terminal having projector function

摘要

A method of controlling a screen of a mobile terminal having a projector function and an apparatus permits outputs of common screen data and dual-processed data output by a display screen and an external screen. A method of outputting screen data in a mobile terminal having a projector function includes: activating a projector module; generating screen data for a display unit displayed on a display unit and screen data for a projector based on the projector module; and performing dual-processing of the generated screen data and outputting the dual-processed screen data to the display unit and the projector module.
