In this state, when the controller 180 receives the long key signal, the controller 180 deactivates both the first touch screen 151a and the second touch screen 151b. .

Also, for example, before the controller 180 receives the long key signal, both the first touch screen 151a and the second touch screen 151b may be in an inactive state. In this state, when the controller 180 receives the long key signal, the controller 180 performs an operation of activating both the first touch screen 151a and the second touch screen 151b. .

The controller 180 sequentially activates the first touch screen 151a and / or the second touch screen 151b when the received key signal corresponds to the short key signal as a result of the determination in step S172. Or deactivated [S174].

FIG. 12 is a diagram illustrating an example of an order in which the first and second touch screens 151a and 151b are activated or deactivated according to the reception of a short key signal. Referring to FIG. 12, an example in which activation states of the first and second touch screens 151a and 151b are changed every time a short key signal is received according to the fourth embodiment of the present invention will be described. First, it is assumed that both the first and second touch screens 151a and 151b are deactivated.

When the first short key signal is received, the controller 180 activates both the first touch screen 151a and the second touch screen 151b [S1731].

When the second short key signal is received, the controller 180 deactivates the first touch screen 151a and maintains an activation state of the second touch screen 151b [S1733].

When the controller 180 receives the third short key signal, the controller 180 activates the first touch screen 151a and deactivates the second touch screen 151b [S1735].

When the controller 180 receives the fourth short key signal, the controller 180 deactivates the first and second touch screens 151a and 151b [S1737].

The fifth embodiment of the present invention can be applied to a mobile terminal having at least one touch screen, and is not necessarily applicable only to a mobile terminal having a plurality of touch screens. Hereinafter, a fifth embodiment of the present invention will be described based on the first touch screen 151a.

The controller 180 receives a touch signal through the first touch screen 151a [S190].

The controller 180 determines whether a touch area corresponding to the received touch signal is greater than or equal to a predetermined size [S191]. The predetermined size may be set based on various criteria. For example, the predetermined size may be determined in units of pixels.

Hereinafter, a touch input having a touch area equal to or greater than the predetermined size will be referred to as "palm touch".

If the touch area corresponding to the received touch signal is not greater than or equal to the predetermined size, the controller 180 executes a function corresponding to the received touch signal [S192]. For example, when the touch signal is received through a specific icon, the controller 180 executes an application corresponding to the specific icon or executes another corresponding function. Also, for example, when there is no object (eg, an icon) corresponding to the received touch signal, the controller 180 maintains an activation state of the first touch screen 151a and performs other functions. May not be performed.

If the touch area corresponding to the received touch signal is greater than or equal to the predetermined size, the controller 180 deactivates the first touch screen 151a as a result of the determination in step S191 [S193].

14 illustrates an example in which the touch area 10 corresponding to the received touch signal is equal to or larger than the predetermined size.

Meanwhile, when the received touch signal corresponds to the palm touch and the received touch is performed on a specific object such as an icon, the controller 180 may selectively perform two operations. FIG. 15 is a diagram for describing an operation of the controller 180 when a touch signal corresponding to the palm touch is received through a specific object.

First, the controller 180 may disable the first touch screen 151a by ignoring a touch input made to the specific object. FIG. 15A illustrates an example in which a touch input 10 corresponding to the palm touch is made on an icon 20 displayed on the first touch screen 151a. The icon 20 illustrated in FIG. 15 is an icon corresponding to an application for managing and transmitting and receiving a message by a short message service (SMS).

Second, the controller 180 may execute a function corresponding to the specific object according to a touch input made to the specific object.

The controller 180 may perform the selective operation in consideration of a first touch area corresponding to the specific object and a second touch area deviating from the specific object among the touch areas corresponding to the received touch signal.

For example, the controller 180 executes a function corresponding to the specific object when the first touch area is larger than the second touch area, and when the first touch area is smaller than the second touch area, The first touch screen 151a may be deactivated. 15B illustrates an example in which the first touch area 10a is smaller than the second touch area 10b.

The selective operation of the controller 180 corresponding to the palm touch and related to the touch input made to the specific object may be preset or changed by the user.

The touch input corresponding to the palm touch may include both the above-described contact touch and the proximity touch.

FIG. 16 illustrates an example in which the fifth embodiment of the present invention is implemented when a proximity touch event occurs. FIG. 16A illustrates a case in which the second body 102 is placed on a desk such that the direction of the second touch screen 151b faces the desk, and FIG. 16B illustrates the first and second touches. The first and second bodies 101 and 102 are placed on the desk so that the directing directions of the screens 151a and 151b are all directed to the desk.

Referring to FIG. 16A, the controller 180 receives a proximity touch signal having a touch area equal to or larger than the predetermined size through the second touch screen 151b, and thus, the second touch screen 151b. ) Can be disabled.

Referring to FIG. 16B, the controller 180 receives proximity touch signals having a touch area of at least the predetermined size through each of the first touch screen 151a and the second touch screen 151b. Accordingly, both the first and second touch screens 151a and 151b may be deactivated.

Through the description of the first to fifth embodiments of the present invention, a control method of the mobile terminal according to the occurrence of a folding event, a location event, a key event, or a touch event and an operation of the mobile terminal 100 for implementing the same. Started.

According to the present invention, a combination of at least two of the above-described first to fifth embodiments is possible. Possible combinations of the foregoing embodiments will now be described by way of example. According to the present invention, it is clear that various combinations of the above-described first to fifth embodiments are possible in addition to the combinations described below.

At least two of the aforementioned folding event, location event, key event, and touch event may occur simultaneously or sequentially. For example, the user opens the first body 101 and the second body 102 (the folding event occurs), and the first touch screen 151a or the second touch screen 151b with respect to the first touch screen 151b. A touch input having a touch area of the predetermined size or more may be applied (the touch event is generated).

As such, when the at least two events occur at the same time, the controller 180 may perform an event processing routine according to a specific event occurrence according to a predetermined priority. For example, in the above-described example, the controller 180 may ignore the occurrence of the touch event and prioritize the occurrence of the folding event to perform a processing routine according to the occurrence of the folding event.

In addition, when the at least two events occur simultaneously and sequentially, the controller 180 may perform an event processing routine according to a combination of the at least two event occurrences.

17 to 19 illustrate a table relating to an event processing method according to at least two event occurrences according to an embodiment of the present invention. FIG. 17 is a table illustrating an event generation processing method according to occurrence of the folding event in consideration of occurrence of at least one other event when the folding event occurs. 18 is a table illustrating an event generation processing method according to occurrence of the location event in consideration of occurrence of at least one other event when the location event occurs. 19 is a table illustrating an event generation processing method according to occurrence of the key event in consideration of occurrence of at least one other event when the key event occurs.

17 to 19, "current state" represents the state of the mobile terminal 100 before the event occurs. In addition, "position" is a column corresponding to the position event, "+" indicates that the direction of orientation of the first touch screen 151a is opposite to the ground surface, and "-" indicates the direction of the second touch screen 151b. Indicates that the direction is the opposite of the earth's surface. Further, "palm touch sensing" is a column corresponding to a touch touch among the touch events, and "proximity" is a column corresponding to a proximity touch among the touch events.

For example, in the state of the mobile terminal 100 before the occurrence of the folding event, which corresponds to "CASE 7" in FIG. (Corresponding to the location event), the palm touch is made to the first touch screen 151a. In this case, when the first body 101 and the second body 102 are closed, the controller 180 may include first and second touch screens 151a and 151b before the folding event occurs. The second touch screen 151b is activated regardless of the "touch activation state".

In addition, for example, in the state of the mobile terminal 100 before the occurrence of the location event, which corresponds to “CASE 5” in FIG. 18, the first and second touch screens 151a and 151b are all activated. This is a case where a touch touch signal is not received through the first and second touch screens 151a and 151b and a proximity touch signal for sensing an external object is received. In this case, when a position event occurs in which the direction of the second touch screen 151b is opposite to the ground surface, the controller 180 deactivates the first and second touch screens 151a and 151b.

For example, in the state of the mobile terminal 100 before the occurrence of the key event corresponding to “CASE 9” in FIG. 19, both the first and second touch screens 151a and 151b are deactivated. The direction in which the second touch screen 151b is directed is opposite to the ground surface, and the palm touch is received through the second touch screen 151b. In this case, when a key event for receiving a long key signal is generated through the second manipulation unit 132, the controller 180 maintains the deactivation state of the second touch screen 151b and the first touch screen 151a. ) Is activated.

Further, for example, in the state of the mobile terminal 100 before the occurrence of the key event, which corresponds to “CASE 18” in FIG. 19, the first touch screen 151a is deactivated and the second touch screen 151b. Is activated, the first body 101 and the second body 102 are half open, and the contact touch and the touch through the first and second touch screens 151a and 151b. This is a case where a touch signal corresponding to a proximity touch is not received. In this case, when a key event for receiving a short key signal occurs through the second manipulation unit 132, the controller 180 deactivates the second touch screen 151b and activates the first touch screen 151a. .
