CELLULAR PHONE FOR REDUCING POWER CONSUMPTION BY USING A TOUCH SENSOR AND A POWER CONSUMPTION REDUCING METHOD, SPECIALLY RELATED TO TURNING OFF A SUB LCD IF THE CELLULAR PHONE IS NOT USED FOR A DESIGNATED TIME, IN ORDER TO REDUCE POWER CONSUMPTION

摘要

PURPOSE: A cellular phone for reducing power consumption by using a touch sensor and a power consumption reducing method are provided to turn off a sub LCD if a cellular phone is not used for a designated time, after information is displayed on the sub LCD, thereby preventing a current from being continuously supplied to the sub LCD. CONSTITUTION: A keypad(10) generates key data according to an inputted key button. A controller(20) executes an operation in accordance with the generated key data, and controls overall operations of a cellular phone. A main LCD(30) is installed inside a folder, and displays an information signal generated while operating the cellular phone. A sub LCD(40) is installed outside the folder, and displays received text message information or absent call information when the folder is closed. A touch sensor(50) senses a contact of a user's body.
