Abstract:
1. A mobile terminal, comprising: a wireless communication unit configured to perform wireless communication; a touch screen configured to switch between an inactivated state in which illumination is not applied to the touch screen and an activated state in which illumination is applied to the touch screen; and a controller configured to: release a locked state of the mobile terminal and switch the touch screen to the activated state, when a plurality of touch inputs on the touch screen in the inactivated state match a predetermined pattern for releasing the locked state of the mobile terminal, wherein the plurality of touch inputs include a first touch input being on one of random positions on the touch screen in the inactivated state, wherein in the inactivated state of the touch screen, the controller is further configured to drive the touch screen with a lower rate sensing signal for sensing the first touch input than in the activated state such that the first touch input on the touch screen is detectable in the inactivated state of the touch screen, wherein the touch screen includes a touch sensor and a display, and is driven in the following drive states: a drive state A in which the touch sensor is in a doze mode and the display is off, a drive state B in which the touch sensor is in an active mode and the display is off, and a drive state C in which the touch sensor is in the active mode and the display is on, wherein the doze mode corresponds to the touch screen being driven with the lower rate sensing signal, and wherein the first touch input is input in the drive state A, the second touch input is input in the drive state B, and the released locked state is in the drive state C.
