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

However, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a block diagram showing the configuration of an electronic device having a touch screen according to the present invention.

Referring to FIG. 1, the electronic device 100 includes a menu providing unit 110, a touch screen 120, a touch recognition module 130, and a controller 140. The electronic device 100 according to the present invention may correspond to a portable terminal including a portable multimedia player (PMP), a personal digital assistant (PDA), a play station portable (PSP), and a mobile communication terminal and a computer or a notebook computer.

The menu providing unit 110 provides a menu or a message related to various functions provided by the electronic device 100. In the present invention, the secret touch registration screen 200a when a secret touch registration request for lock setting is input. It provides and, when requesting the unlock in the locked state provides a unlock screen (200b). The secret touch registration screen 200a or the unlock screen 200b is, for example, as shown in FIGS. 2A and 2B, and determines the effective area 10 that determines the touch as a valid input and the touch as an invalid input. The effective area 10 includes nine small areas 11 to 19 in the form of a 3 * 3 matrix. In this case, the effective area 10 is not limited to the example shown in the figure (a square of 3 * 3 matrix form), and may be modified in various shapes.

The touch screen 120 displays a menu or a message provided by the menu providing unit 110 and displays a secret touch registration screen 200a or a unlock screen 200b.

The touch recognition module 130 recognizes a touch input to the touch screen 120 and recognizes a touch input to the effective area 10 of the secret touch registration screen 200a or the unlock screen 200b. In this case, a plurality of touches simultaneously input by a plurality of fingers or a plurality of objects are recognized as multi-touch, and a touch continuously input within a preset time is recognized as a continuous touch. In the multi-touch, simultaneous input means a predetermined time error range is set, and continuous touch means that one small area of the small areas 11 to 19 of the effective area 10 is touched twice continuously within a predetermined time. Is most preferred.

Accordingly, when a plurality of touches are simultaneously input to the effective area 100 of the secret touch registration screen 200a or the unlocking screen 200b, the touch recognition module 130 determines that they are multi-touch, Detect a plurality of corresponding multi-touch points.

Detects a continuous touch point corresponding to the input touch, and transmits only one continuous touch point to the controller 140. This is because, in the case of continuous touch, since the touch is generated in the same small area (one of 11 to 19), the controller 140 may determine the small area to which the continuous touch point belongs even with only one continuous touch point.

The controller 140 registers each of the multi-touch points or the continuous touch points detected through the secret touch registration screen 200a as a secret touch. If the secret touch is for a total lock setting, the control unit 140 registers as a full lock secret touch. In case of secret touch for lock setting, register as partial lock secret touch. The secret touch corresponds to a password and a password input for the conventional lock setting.

Meanwhile, the controller 140 determines whether each touch point detected through the unlock screen 200b corresponds to a touch point preset for lock setting, that is, a touch point registered in advance as a secret touch. Release it.

For example, when divided into a multi-touch and a continuous touch, for example, to register a multi-touch one touch full lock secret touch or partial lock secret touch, when the entire lock or partial lock, the control unit 140 touch If each of the multi-touch points detected by the recognition module 130 is a multi-touch point belonging to the small area (one of 11 to 19) registered in advance as a secret touch, and if applicable, the entire lock is released or partially locked. Deactivate the function.

When one or more consecutive touches are registered as a full lock secret touch or a partial lock secret touch, and in the case of full lock or partial lock, the controller 140 registers each successive touch point detected by the touch recognition module 130 as a secret touch in advance. It is determined whether it is a continuous touch point belonging to the small area (one of 11 to 19), and if so, releases the entire lock or the partially locked function.

The partial lock function corresponds to various functions provided by the electronic device 100, and includes, for example, a text message function, a telephone function, or a photo album viewing function.

On the other hand, if each touch point detected by the touch recognition module 130 does not correspond to a touch point registered in advance as a secret touch, the controller 140 controls the menu providing unit 110 to unlock the screen 200b. To be displayed on the screen.

3A and 3B are flowcharts illustrating an example of a method of operating an electronic device having a touch screen according to the present invention.

When inputted within (S505), the electronic device 100 determines that it is a continuous touch and detects one first continuous touch point (S507).

When the touch is input (S509), the electronic device 100 detects the first touch point by the input touch (S511), and registers the first continuous touch point and the first touch point as a secret touch (S509). S513). Here, in the present invention, since the number of touches that can be input for registering the secret touch is not determined, when the user inputs a touch (including multi-touch or continuous touch) and presses the 'OK' key or the 'OK' key, It is preferable that the electronic device 100 deletes the secret touch registration screen 200a from the screen and detects the touch point with the input touch to register the detected touch point as the secret touch.

In addition, when the lock request is input, the electronic device 100 sets the lock to operate in the lock mode (S515).

Thereafter, when the unlock request is input (S517), the electronic device 100 displays the unlock screen 200b on the touch screen 110 (S519).

When the plurality of continuous touches are input within a preset time (S521), the electronic device 100 determines that the touches are continuous, and detects one second continuous touch point (S523).

Then, if it is determined whether the touch is input (S525), the electronic device 100 detects the second touch point corresponding to the touched position (S527).

Then, the electronic device 100 determines whether each of the detected second consecutive touch points and the second touch points corresponds to the first continuous touch point and the first touch point registered in advance as a secret touch (S529). S531), the lock is released (S533).

In the above description, a method of setting or unlocking a lock by combining a single touch or a combination of a continuous touch and a conventional touch (touch with one finger or an object, such as when entering a password) has been described. .

However, the method for setting or releasing the lock in the electronic device according to the present invention includes a method of using a combination of multi-touch, a method of using a combination of continuous touch, a method of combining a multi-touch and a continuous touch, and a combination of multi-touch and touch. Or a combination of touch and multi-touch and continuous touch. Accordingly, the number of cases in which the password can be set is more diverse than in the prior art.

For example, as shown in FIG. 6, when referring to a touch input to the unlock screen 200b displayed on the touch screen 120 of the electronic device 100, the user continuously presets a small area of '12'. After touching in time, if the '14' small area is touched, and then '15' and '16' small area at the same time, the electronic device 100 recognizes the continuous touch point, touch point and multi-touch point Then, one continuous touch point corresponding to the '12' small region, a touch point corresponding to the '14' small region, and two multi-touch points corresponding to the '15' and '16' small regions are detected. The electronic device 100 releases the lock if it is determined whether the detected continuous touch point, the touch point, and the multi-touch point correspond to a touch point registered with a secret touch in advance.
