For convenience of explanation, it is assumed that the mobile terminal referred to below includes at least one of the components shown in FIG.

3 is a flowchart illustrating a flow of a display control method according to the present invention.

The controller 180 performs the first screen lock mode on the touch screen 151 (S310). The touch screen 151 receives a touch operation (S320). The controller 180 determines whether the input touch operation is a prescribed touch operation for switching the first screen lock mode to the second screen lock mode (S330). If it is determined that the prescribed touch operation, the controller 180 performs the second screen lock mode (S340).

The term "screen lock mode" as used herein refers to a mode in which a certain limit exists in the touch operation input to the touch screen 151. For example, in the normal mode other than the screen lock mode, the controller 180 may recognize all touch operations of the user with respect to the touch screen 151 as meaningful operations, and may perform corresponding control operations. . However, when in the screen lock mode, the touch operation may be set so as not to recognize a touch operation on a specific area or the entire area on the touch screen 151.

The screen lock mode or lock screen is to prevent a mobile terminal malfunction due to a sensitive touch operation. For example, when the mobile terminal 100 is in a pocket in a normal mode state other than the screen lock mode, an unintended touch operation may be performed on the touch screen 151. When set to the screen lock mode state, even if the touch screen 151 is touched, a specific function of the mobile terminal 100 may be prevented from being performed.

When the screen lock mode is performed, the controller 180 may temporarily turn off the touch recognition function of the touch screen 151. That is, it may be maintained in the touch deactivated state. The touch screen 151 may recognize a touch operation through a device capable of a touch recognition function such as a touch panel. In the present invention, when operating in the screen lock mode, it can be set to the touch inactive state. In addition, the controller 180 may set the entire screen area of the touch screen 151 to the touch deactivated state, or optionally, set the touch deactivated state to some screen areas.

In one embodiment of the present invention, the screen lock mode for the touch screen 151 may be maintained step by step. That is, in performing the screen lock mode, a step may be set to adjust the touch recognition range according to each step. For example, the screen lock mode of the first step may be set to the screen lock mode for the entire area of the touch screen 151, and the screen lock mode of the second step may be set to the partial area of the touch screen 151. Can be set to screen lock mode.

In the case of the first screen lock mode, the touch recognition function may be set to be turned off or limited in the entire screen area of the touch screen 151. Thus, when in the first screen lock mode, touching any area of the touch screen 151 is not recognized as a meaningful user action.

Meanwhile, in the second screen lock mode, some screen areas of the touch screen 151 may be set to the touch inactive state. That is, some areas of the entire area of the touch screen 151 may be limited to the touch recognition function, but other areas may be set so that the touch recognition function is normally recognized. In the latter case, the controller 180 may display an execution screen of the application and set the touched screen.

The present invention can maintain the screen lock mode step by step, it can be set so that each mode can be changed mutually.

Referring back to FIG. 3, in step S310, the controller 180 performs a first screen lock mode. The controller 180 performs the first screen lock mode when no user action (including a touch action) has been input from the user or when there is a user command to enter the screen lock mode.

In step S320, the touch screen 151 receives a touch gesture from the user. Here, since it is in the first screen lock mode, there is a limitation in the touch recognition function for the entire area of the touch screen 151. Therefore, even if the touch screen 151 performs a touch operation, the touch screen 151 is not connected to a meaningful control operation of the mobile terminal 100. However, exceptionally, even in the case of a touch operation for switching the first screen lock mode to the second screen lock mode, the controller 180 may determine the touch action and switch to the second screen lock mode. have.

In operation S330, the controller 180 determines whether the input touch operation is a prescribed touch operation for switching to the second screen lock mode. Here, the defined touch operation may exist in various ways. For example, a touch operation for a specific point, an action of pressing a specific button, a touch drag action of a specific pattern, and the like may exist in various ways. The flicking operation of moving a touch from one side to the other or the pinching operation of narrowing or widening the two touch points may be various. If it is determined that the input touch operation is a prescribed touch operation for switching to the second screen lock mode, the controller 180 switches to the second screen lock mode with respect to the touch screen 151. The controller 180 maintains the first screen lock mode when it is not determined to be a prescribed touch operation.

In operation S340, the controller 180 performs a second screen lock mode according to an input of a prescribed touch operation. As described above, in the second screen lock mode, some areas of the entire area of the touch screen 151 may be set to a touch inactive state, and in the remaining areas, an execution screen of a specific application may be displayed.
