May be mounted on the first rear case 225. If so, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state are protected by the second body 205. Furthermore, even if the camera 121 of the second body is not provided separately, the camera 121 of the first body may be rotatably formed so that the camera 121 of the second body may be photographed up to the photographing direction of the camera 121 of the second body. .

The terminal 100 illustrated in FIGS. 1 to 3 may be operated in a communication system capable of transmitting data through a frame or packet, including a wired / wireless communication system and a satellite-based communication system. It can be configured to.

Hereinafter, referring to FIG. 4, a communication system capable of operating a terminal according to the present invention will be described.

The communication system may use different air interfaces and / or physical layers. For example, a radio interface usable by a communication system may include frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (Code Division). Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE)), Global System for Mobile Communications (GSM), etc. May be included. Hereinafter, for convenience of description, the description will be limited to CDMA. However, it is a matter of course that the present invention is applicable to all communication systems including the CDMA wireless communication system.

As shown in FIG. 4, the CDMA wireless communication system includes a plurality of terminals 100, a plurality of base stations (BS) 270, and base station controllers (BSCs) 275. ), And a mobile switching center (MSC) 280. The MSC 280 is configured to be connected to a public switched telephone network (PSTN) 290 and is also configured to be connected to BSCs 275. The BSCs 275 may be coupled to the BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Thus, a plurality of BSCs 275 may be included in the system shown in FIG.

Each BS 270 may include at least one sector, and each sector may include an omnidirectional antenna or an antenna pointing radially out of BS 270. In addition, each sector may include two or more antennas of various types. Each BS 270 may be configured to support a plurality of frequency assignments, each of which has a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sectors and frequency assignments may be called a CDMA channel. BS 270 may be referred to as a Base Station Transceiver Subsystem ('BTSs'). In this case, the word "base station" may be called the sum of one BSC 275 and at least one BS 270. The base station may also indicate “cell site”. Alternatively, each of the plurality of sectors for a particular BS 270 may be called a plurality of cell sites.

As shown in FIG. 4, a broadcasting transmitter (BT) 295 transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT 295.

In addition, FIG. 4 illustrates multiple satellite positioning systems (GPS) satellites 300. The satellites 300 help to locate the at least one terminal of the plurality of terminals 100. Although two satellites are shown in FIG. 4, useful location information may be obtained by two or less or more satellites. The location information module 115 shown in FIG. 1 cooperates with the satellites 300 to obtain desired location information. Here, the location can be tracked using not only the GPS tracking technology but also all the technologies capable of tracking the location. In addition, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

During typical operation of a wireless communication system, BS 270 receives a reverse link signal from various terminals 100. At this time, the terminals 100 are connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by a particular base station 270 is processed within by the particular base station 270. The data generated as a result of the processing is transmitted to the connected BSC 275. BSC 275 provides call resource allocation and mobility management functionality, including the organization of soft handoffs between base stations 270. In addition, the BSC 275 transmits the received data to the MSC 280, and the MSC 280 provides an additional transmission service for connection with the PSTN 290. Similarly, PSTN 290 connects with MSC 280, MSC 280 connects with BSCs 275, and BSCs 275 send BSs 270 to transmit a forward link signal to terminals 100. ).

Next, a method of changing a keypad display according to a keypad setting change in a mobile terminal according to an embodiment of the present invention will be described. The mobile terminal 100 according to the present embodiment may change key arrangement and display keys of the keypad when the display position and size of the keypad are changed in relation to touch or proximity.

Touching refers to a state in which a pointing device contacts the display screen. In this case, the positioning tool refers to a tool for designating a specific point on the display screen, and includes a user finger, a stylus, a light pen, and the like.

Proximity refers to a state in which the positioning tool does not touch the display screen and is a distance from the screen.

That is, the mobile terminal according to an embodiment of the present invention may detect the touch and the proximity through the sensing unit 140. The sensing unit 140 may include a touch sensor for detecting a touch and / or a proximity sensor for detecting a proximity.

The proximity sensor detects when the positioning tool approaches a predetermined distance from the screen and generates and outputs a corresponding sensing signal. That is, the proximity sensor may detect and output a distance (proximity distance) between the positioning tool and the sensor based on the capacitance changing according to the approach distance of the positioning tool. In addition, the proximity sensor may output position information (coordinate value) of a specific point vertically corresponding to the positioning tool when the positioning tool approaches.

In addition, the proximity sensor may detect a speed (proximity speed) at which the positioning tool approaches the display screen or a speed (proximity speed) at which the positioning tool moves away from the display screen. In addition, the proximity sensor may detect a proximity drag in which the proximity point moves while the positioning tool is located within a predetermined distance from the display screen.

In the present specification, a capacitive proximity sensor has been described as an example, but may be implemented by changing to various types of proximity sensors.

The touch sensor outputs position information (coordinate value) of the corresponding point where the contact of the positioning device is detected. The touch sensor may be implemented as various types of touch pads, such as capacitive and static pressure. In addition, the touch pad may be implemented in the form of a touch screen by forming a mutual layer structure with the display unit 151, so that the display unit 151 may be used as an input device as well as a display device.

The touch sensor may detect a drag distance, a drag direction, a drag speed, and a flick direction. The drag refers to a state in which a touch point moves (changes) while a touch is maintained.

5 is a diagram illustrating an example in which touch and proximity are sensed.

As illustrated, the sensing unit 140 may detect proximity when the positioning tool is located in an area within a predetermined distance D from the display unit 151 (a). Here, the predetermined distance (D) refers to a proximity detection area in which the proximity sensor can detect the approach of the positioning tool. Therefore, when the positioning tool (for example, the user's finger) is positioned in the proximity sensing area, the sensing unit 140 may detect the approach of the positioning tool.

On the other hand, when the positioning tool is located in a space outside the proximity sensing area, the sensing unit 140 may not detect the positioning tool (b). That is, when the positioning tool existing in the proximity sensing region is out of the proximity sensing region, the controller 180 recognizes that the proximity is released.

In addition, the sensing unit 140 may detect a contact on the screen of the display unit 151. That is, when the positioning tool contacts the screen of the display unit 151, the sensing unit 140 may detect a touch of the positioning tool (c).

On the other hand, when the positioning tool is separated from the display unit 151, the sensing unit 140 may not detect the positioning tool. Therefore, the mobile terminal 100 recognizes that the touch is released.

If a keypad setting such as a keypad display position and / or keypad size is changed by an input such as proximity and / or touch, the controller 180 changes the keypad display based on the changed setting. That is, the controller 180 can change the key arrangement, keypad shape, display key, key arrangement, etc. of the keypad.

6 is a flowchart illustrating a keypad display method of a mobile terminal according to an embodiment of the present invention. This embodiment describes changing the keypad display according to the display position of the keypad.

First, the sensing unit 140 may detect a touch on the screen of the display unit (S101). That is, when the positioning tool is touched at one point of the keypad displayed on the display unit 151, the sensing unit 140 detects the touch of the positioning tool.

The controller 180 checks whether the sensing signal transmitted from the sensing unit 140 is a keypad setting change command (S103). Here, to distinguish whether the detected touch is for data input or input for changing the keypad setting, the controller 180 recognizes the keypad setting change command when the touch is maintained for a predetermined time (2 to 3 seconds) or more. And, if the holding time of the touch is less than a predetermined time can be implemented to recognize as a data input.

In the present exemplary embodiment, the keypad setting change command input is distinguished from the data input using the long touch as an example. However, the proximity setting may be used to distinguish the setting change command input from the data input. For example, the mobile terminal 100 may recognize the touch as a command for data input when a touch is sensed and recognize as a keypad setting change command when a proximity is detected.

After the keypad setting change command is input, the controller 180 checks whether the display position of the keypad is changed (S105). That is, when dragging is performed, the controller 180 determines the drag distance and the direction through the sensing unit 140 and changes the display position of the keypad according to the identified drag distance and the direction. If the drag distance is greater than or equal to the predetermined distance, the controller 180 recognizes the command as a command for changing the keypad display position.

As a result of the check, when the display position of the keypad is changed, the controller 180 can change the keypad display according to the changed keypad display position (S107). That is, when the keypad display position is changed, the controller 180 can change the arrangement and shape of the keys constituting the keypad according to the changed display position.

Meanwhile, if the sensing signal is not a keypad setting change command in step S103, the controller 180 may recognize a key selection corresponding to the detected touch point in operation S115. Accordingly, the information assigned to the selected key may be input as data and displayed on the display unit 151 or the specific function assigned to the selected key may be executed.

7 is an exemplary view illustrating a display position where a keypad may be displayed in the mobile terminal according to the embodiment of FIG. 6.

As shown in FIG. 8A, when a user's finger touches a point on the keypad displayed on the display unit 151, the sensing unit 140 detects a touch of the user's finger. If the detected touch is maintained for a predetermined time or more, the controller 180 recognizes the command as a command for changing a keypad setting. For example, when the time for which the touch is maintained elapses for 3 seconds, the controller 180 recognizes the touch input as a command for changing a keypad setting, and when the touch holding time is less than 3 seconds, for selecting a key for data input. Recognize.

Subsequently, when the user's finger moves from one point to another, the controller 180 may change the keypad display position according to the moving direction. For example, when the user's finger is dragged upward, the controller 180 changes the keypad display position to the 'A1' area. At this time, the controller 180 checks whether a keypad display change is required in accordance with the keypad display position change. If the result of the check does not require changing the keypad display, only the display position of the keypad is changed.

In addition, the controller 180 may change the position (information display position) where the input data and various information are displayed as the keypad display position is changed.

Referring to FIG. 8B, when a user's finger is touched on the keypad displayed at the bottom of the screen of the display unit 151, the sensing unit 140 detects this and notifies the controller 180. After the touch is detected, if a drag operation is performed to the left side, the controller 180 determines the dragged direction. The controller 180 changes the keypad display position to the 'A3' area based on the grasped drag direction.
