Abstract

A method and a mobile communication terminal for providing a private protection service by using an LCD having a variable viewing angle are provided to mount a variable viewing angle LCD on the mobile terminal, register an application requiring private protection as a private protection application to change the viewing angle of LCD, thereby preventing user's information from being exposed. One of various applications provided in a mobile communication terminal is performed(S400). It is determined whether or not the application performed by the mobile terminal is registered as a private protection application(S402). A viewing angle reducing signal is created to reduce a viewing angle of the mobile terminal if the performed application is registered as the private protection application(S406). If it is determined that the application is not registered as the private protection application, the performed application creates a null signal of notifying that the private protection application is not used. The created null signal is transmitted to the variable viewing angle displayer to maintain a normal viewing angle of the mobile terminal.
