Abstract: A method of controlling a screen of a mobile terminal 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 includes: generating screen data for displaying on a display unit and screen data for displaying on an external display unit; performing dual-processing of the generated screen data; detecting a progress state of the performance of a function of the mobile terminal; embedding progress data to the dual-processed screen data for the external display unit representing the progress state of the performance of the function of the mobile terminal; and outputting the dual-processed screen data for the display unit and transmitting the dual-processed screen data for the external display unit to the external display unit, wherein the dual-processed screen data for the display unit does not have embedded therein the progress data representing the progress state.

Abstract: 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.

Abstract: A method for processing a multi-touch input for a mobile device having a touch screen of a resistive overlay type which is normally incapable of recognizing a multi-touch input. A first data based on a first touch is displayed and a second touch is detected while the first touch is maintained. An intermediate data unexpectedly occurring between the first and second touches is treated as invalid data and removed when one of the first and second touches is released. Then a second data based on the second touch is displayed. This method makes it possible to properly recognize a multi-touch input through software-based technique, while reducing unexpected input errors caused by a multi-touch input and thus permitting a user's quick input action.

Abstract: A mobile device has a projector module which projects data onto an external display screen. A method for displaying data in the mobile device includes activating the projector module and detecting output property information in at least one of content and an application. The method further includes determining a display format of output data of the content or the application based on the detected output property information. Also, the method includes projecting the output data in the determined display format through the activated projector module in a horizontal or vertical orientation. Such a display format may be changed according to a user's preference or a device presetting environment.
