4 is a flowchart illustrating a method of displaying a touch lock symbol according to an embodiment of the present invention.

4, when the touch input or the key input is not present for a predetermined period of time, or according to a command of the user, the control unit 180 controls the operation of the touch lock (touch) lock state (S410). When setting the touch lock state, the control unit 180 preferably terminates the execution application except for the audio application. Here, the audio application refers to an application that executes only audio data among contents including audio data. For example, this may be an application for playing music or an application for receiving and reproducing a radio broadcast.

When the touch lock state is set, the control unit 180 generates a symbol (hereinafter referred to as 'touch lock symbol') indicating that the touch lock state is present (S420). Preferably, the touch lock symbol includes at least one of an image and text. For example, the touch lock symbol may include a movable bar-shaped image, or may comprise text or special symbols to include information about a user's action to release the touch lock state.

If the audio application is running in the touch lock state (S430-Y), the controller 180 displays the generated touch lock symbol in the middle area of the touch screen (S440). The touch region capable of sensing the touch of the touch screen may be divided into an upper region including the upper edge of the touch screen, a lower region including the lower edge of the touch screen, and an intermediate region between the upper and lower regions of the lower filter . The top region, middle region and bottom region may be the same size, but may be different.

However, if the audio application is not being executed (S430-N), the controller 180 may display the touch lock symbol in the lower area of the touch screen (S450).

On the other hand, when a communication event occurs in the touch lock state, the controller 180 moves the touch lock symbol to the middle area of the touch screen and displays it (S470). Here, the communication event means reception of a missed call, reception of a message or mail, reception of updated information at a social network service site, reception of information from a RSS (Really Simple Syndication) reader, and the like.

As described above, when the audio application is being executed or the communication event is generated in the touch lock state, the touch lock symbol is displayed in the middle area of the touch screen to display a user command for dragging in the upper direction of the touch screen, You can receive user commands to drag. From the display position of the touch lock symbol, the user can also check whether a communication event has occurred or whether an audio application is running.

On the other hand, a plurality of communication events may occur in the touch lock state. By varying the size of the touch lock symbol in response to the communication event, the user can more intuitively confirm the information about the occurrence of the communication event.

5 is a reference diagram illustrating a method of displaying notification information of a communication event according to an embodiment of the present invention.

Referring to FIG. 5, when a communication event occurs (S510), the controller 180 generates notification information indicating that a communication event has occurred (S520). The notification information may include at least one of an icon, text, and an image.

Meanwhile, the controller 180 determines whether the size of the notification information is equal to or larger than the size of the touch lock symbol (S530).

If it is determined that the size of the notification information is larger than the size of the touch lock symbol (S530-Y), the controller 180 enlarges the size of the touch lock symbol (S540) and superimposes the notification information on the touch lock symbol S550). However, if it is determined that the size of the notification information is smaller than the size of the touch lock symbol (S530-N), the control unit 180 superimposes the notification information on the touch lock symbol.

As described above, since the size of the touch lock symbol is enlarged corresponding to the notification information, the amount of the notification information can be graphically displayed.

The following explains how to release the touch lock state according to user action.

6 and 7 are flowcharts illustrating a method of releasing a touch lock state according to an operation of a user according to an embodiment of the present invention.

Referring to FIG. 6, in a touch lock state, a touch lock symbol is displayed in one area of the touch screen (S610). Preferably, the touch lock symbol is displayed in an intermediate area of the touch screen.

On the other hand, the controller 180 receives a user command for touching and dragging the area where the touch lock symbol is displayed (S620). Preferably, the controller 180 performs an operation only for the touch input through the area where the touch lock symbol is displayed.

If the drag direction includes the first direction (S630Y-Y), the controller 180 moves the touch lock symbol in the first direction corresponding to the drag and releases the touch lock state (S640). Preferably, the first direction is a bottom direction of the touch screen. Then, the control unit 180 displays a screen related to the specific application (S650). Preferably, the screen associated with a particular application is a screen for controlling a communication event or a screen for controlling an audio application.

On the other hand, if the drag direction includes the second direction (S660-Y), the controller 180 moves the touch lock symbol in the second direction corresponding to the drag and releases the touch lock state (S670). Preferably, the second direction is the upper direction of the touch screen as a direction opposite to the first direction. Then, the control unit 180 displays a menu screen for starting execution of all applications.

However, if the drag direction does not include the first direction and the second direction (S660-N), the controller 180 does not move the touch lock symbol corresponding to the drag, and maintains the touch lock state. That is, the received user command is ignored, and the display of the touch lock screen is maintained.

Only the case where the touch lock symbol is displayed in the middle area of the touch screen in the present embodiment has been described. The touch lock symbol can be displayed in the lower area of the touch screen. In this case, since the touch-lock symbol does not move in the first direction, the controller 180 does not release the touch-lock state but maintains the existing screen, that is, the touch-lock state.

Referring to FIG. 7, a method of releasing a touch lock according to a user's operation of dragging in a first direction will be described in detail.

Upon receiving a user command for touching the area where the touch lock symbol is displayed and dragging in the first direction (S710), the touch lock state is canceled. Then, the control unit 180 determines whether a communication event has occurred in the touch lock state (S720). If the generated communication event is one (S730-N), the control unit 180 displays the detailed information of the communication event (S740).

However, if there are a plurality of generated communication events (S730-Y), the communication event list is generated based on the brief information of the communication event and displayed (S750). The control unit 180 can generate a communication event item using at least one of the type of the communication event, the time of occurrence, the content of the communication event, and the counterpart information related to the communication event. Upon receiving a user command for selecting a specific communication event from the communication event list (S760-Y), the controller 180 executes the selected communication event to display detailed information of the selected communication event (S770). For example, if the selected communication event is a reception of a missed call, the control unit 180 generates detailed information on reception of the missed call using the time information of the missed call, the number of missed calls, the caller information, and the like Display.

If the audio application is being executed (S780-Y), the control unit 180 displays a control key for controlling the audio application (S790).

Hereinafter, the present invention will be described in more detail with reference to the drawings.
