Abstract:
1. A portable terminal device, comprising: a first display module comprising a first display surface; a second display module comprising a second display surface; a first detecting module which detects an input to the first display surface; a second detecting module which detects an input to the second display surface; a function control module which sets and releases a keylock function for disabling the first detecting module and the second detecting module; and a storage module which stores a releasing condition for releasing the keylock function, the releasing condition including a combination of inputs, wherein the combination of inputs includes an ordered sequence of two or more steps, wherein a first one of the two or more steps comprises a number of inputs to one of the first and second display surfaces, and wherein a second subsequent one of the two or more steps comprises a number of inputs to a different one of the first and second display surfaces than the first step, wherein the function control module releases the keylock function with respect to at least one of the first detecting module and the second detecting module when a sequence of inputs detected by the first and second detecting modules match with the releasing condition stored in the storage module while the keylock function is being set, wherein the function control module turns off the second display module when the keylock function with respect to the first detecting module, among the first detecting module and the second detecting module, is released, wherein the function control module turns off the first display module when the keylock function with respect to the second detecting module, among the first detecting module and the second detecting module, is released, and wherein the releasing condition includes an input in which one of the first display module and the second display module is touched, and the touched position is moved to the other display module while the touch is kept.
