The same reference numbers are used throughout the drawings to refer to the same or like parts. Detailed descriptions of well-known functions and structures incorporated herein may be omitted to avoid obscuring the subject matter of the present invention.
A mobile communication terminal according to the present invention has a wide display unit, including a telecommunication appliance or multimedia appliance having a display unit, such as a mobile terminal, mobile phone, Personal Digital Assistant (PDA), smart phone, and applications thereof.
Referring to FIG. 1, the mobile communication terminal includes a radio frequency (RF) unit 100, input unit 200, sensor unit 250, controller 300, repartition unit 310, rotation unit 320, storage unit 400, wide display unit 500, standard area 510, and extension area 520.
The RF unit 100 performs general wireless communication between the mobile communication terminal and a mobile communication network. For example, the RF unit 100 performs transmission and reception of sound data through a wireless network, transmission and reception of a character message, and transmission and reception of a multimedia message.
The input unit 200 may be at least one of a general keypad, touch screen, touch pad, and scroll wheel. The input unit 200 outputs a signal corresponding to a user key input to the controller 300 in order to control operation of a mobile communication terminal. In more detail, the input unit 200 includes a key for generating a signal to display data in the standard area 510 of the wide display unit 500 on a full screen, and a key for generating a signal to select a content displayed in the extension area 520 of the wide display unit 500 and to display the content in the standard area 510.
The sensor unit 250 is a rotation detection sensor, such as a gyro sensor or a geomagnetic sensor, for detecting a rotation of the wide display unit 500. The sensor unit 250 outputs, when a rotation of the wide display unit 500 is detected, a detected rotation result to the controller 300.
The controller 300 controls general operations performed in the mobile communication terminal. The controller 300 includes a transmission means for encoding and modulating a signal to be transmitted from the RF unit 100, and a reception means for decoding and demodulating a received signal. The controller preferably 300 further includes a modem and codec.
The controller 300 receives a rotation result of the wide display unit 500 corresponding to a rotation of the wide display unit 500 from the sensor unit 250. The controller 300 calculates a rotation angle of the wide display unit 500 and determines a rotation direction thereof according to the received rotation result. In this case, the wide display unit 500 and the mobile communication terminal can be rotated together or independently.
In more detail, the controller 300 includes the repartition unit 310 for repartitioning an area of the wide display unit 500 into the standard area 510 and the extension area 520 according to the rotation result of the wide display unit 500 received from the sensor unit 250. The repartition unit 310 repartitions the standard area 510 and the extension area 520, and resets a size and position of the standard area 510 and the extension area 520.
The controller 300 adjusts a size of the data displayed in the standard area 510 and the user's additional information displayed in the extension area 520 according to the reset standard area 510 and extension area 520.
The controller 300 includes a rotation unit 320 for rotating the data and user's additional information in a direction opposite to a rotation direction of the wide display unit 500. For example, when the wide display unit 500 rotates 270° clockwise (or 90° counterclockwise), the rotation unit 320 rotates, relative to the wide display unit 500, a screen displayed in the wide display unit 500 by the same angle and in the direction opposite to the rotation direction of the wide display unit 500, and outputs the screen to the controller 300, thereby sustaining the angle of initial orientation of the displayed screen relative to the external. The controller 300 further displays the screen received from the rotation unit 320 in the wide display unit 500.
The screen may be a screen of the data displayed in the standard area 510, the user's additional information displayed in the extension area 520, and data displayed in the wide display unit 500 in a full screen mode. The data includes image data and character data displayed in the standard area 510. The data further includes image data and character data of the user's additional information displayed in the extension area 520.
The controller 300 receives a selection signal from the input unit 200 for displaying in detail, in the standard area 510, a content of the user's additional information displayed in the extension area 520. The controller 300 then displays data corresponding to the content of the selected user's additional information in the standard area 510 of the wide display unit 500. The controller 300 may update and display the user's additional information displayed in the extension area 520 of the wide display unit 500 at a time set by the user.
If the controller 300 receives a signal for displaying the data displayed in the standard area 510 in the entire wide display unit 500 from the input unit 200, the controller 300 displays the data on a full screen of the wide display unit 500.
The storage unit 400 stores information (for example, information of a setting state and menu) related to operation of a program for controlling the mobile communication terminal, by the control of the controller 300. The storage unit 400 further stores a screen ratio of the standard area 510 and extension area 520 for displaying as the standard area 510 and extension area 520 in the wide display unit 500. The storage unit 400 stores an address of a web page for displaying a search window corresponding to the user's additional information to display in the extension area 520 and an address of a web page for receiving a Really Simple Syndication (RSS).
The wide display unit 500 displays an operating state, operation result, and information performed in the mobile communication terminal by the control of the controller 300. The wide display unit 500 can use a display unit such as a Liquid Crystal Display (LCD) and an Organic Light Emitting Diodes (OLED) display. A screen ratio of the wide display unit 500 is m:n, wherein ‘n’ is greater than or equal to ‘m’. The wide display unit 500 includes the standard area 510 for displaying data and the extension area 520 for displaying user's additional information.
A screen ratio of the standard area 510 is m:p, and a screen ratio of the extension area 520 is m:n−p. In an exemplary embodiment of the present invention, a rectangular form of wide display unit 500 is described, however other focus including a square form of wide display unit 500 can be used.
The data displayed in the standard area 510 are various data of operating state, operation result, and information performed in the mobile communication terminal. The user's additional information displayed in the extension area 520 is information of a search window connected to an Internet search web page set by the user and information corresponding to the RSS received from an address of a web page stored in the storage unit 400 by the user in order to receive the RSS.
FIG. 2 is a flowchart illustrating a method of controlling a wide display unit in a mobile communication terminal according to an exemplary embodiment of the present invention. FIG. 3 is a flowchart illustrating a process of displaying a standard area and an extension area of the wide display unit in the method of FIG. 2. FIGS. 4A and 4B, and FIGS. 5A and 5B, are examples of display screens illustrating the method of FIG. 2.
Referring to FIGS. 1 to 5, the controller 300 partitions an area of the wide display unit 500 into the standard area 510 and the extension area 520 according to a screen ratio of the wide display unit 500 stored in the storage unit 400 in step S201.
Step S201 is described in more detail in FIG. 3. The controller 300 displays data in the standard area 510 and user's additional information in the extension area 520 of the wide display unit 500 in step S301, as shown in FIG. 4A.
In this case, a search window 521 in the extension area 520 is connected to an Internet search web page that is set by the user in the user's additional information. An RSS window 522 in the extension area 520 receives update information of information that is set to an Internet search web page by the user in the user's additional information and displays the update information. In the example of FIG. 4A, an RSS displayed in RSS window 522 displays that update information of a mini home page and a brief comment written with up to 30 characters about a movie exists in a visitor's book.
The controller 300 determines whether a signal for selecting the user's additional information is received from the input unit 200 in step S305.
If a signal for selecting the user's additional information is not received from the input unit 200, the process continues in step S203.
If a signal for selecting the user's additional information is received from the input unit 200, the controller 300 displays data of the selected user's additional information in the standard area 510 in step S307. In more detail, when a search word is input to the search window 521, the controller 300 connects to an address of a web page stored in the storage unit 400, searches for the search word, and displays a search result in the standard area 510. Further, when the controller 300 receives a selecting signal of a brief comment written with up to 30 characters about a movie from the input unit 200 on the RSS window 522, the controller 300 connects to a web page stored in the storage unit 400 and displays data about the brief comment written with up to 30 characters about a movie in the standard area 510. In this case, the search window 521 and the RSS window 522 can be changed to other additional information set by the user.
Returning to FIG. 2, the controller 300 determines whether a signal for changing a mode of the data displayed in the standard area 510 to a full screen mode is received from the input unit 200 in step S203. If a signal for changing a mode of the data displayed in the standard area 510 to a full screen mode is received from the input unit 200, the controller 300 extends the data displayed in the standard area 510 to an entire size (i.e. a full screen mode) of the wide display unit 500 and displays the extended data in the standard area 510 in step S205. A screen displaying the extended data in the wide display unit 500 is shown in FIG. 5A.
The controller 300 determines whether a rotation of the wide display unit 500 is detected by the sensor unit 250 in step S207. If a rotation of the wide display unit 500 is detected by the sensor unit 250, the controller 300 determines whether data are displayed in a full screen mode in the wide display unit 500 in step S209.
If data are displayed in a full screen mode in the wide display unit 500, the rotation unit 320 rotates the data displayed in the full screen mode by the same rotation angle but in the direction opposite to the rotation direction of the wide display unit 500, and outputs the rotated data to the controller 300 in step S211.
The controller 300 displays the rotated data received from the rotation unit 320 in the wide display unit 500 in step S213, thereby completing the process. A screen displaying the rotated data in the wide display unit 500 is shown in FIG. 5B.
If data are not displayed in a full screen mode in the wide display unit 500 at step S209, the repartition unit 310 repartitions the standard area 510 and the extension area 520, resets a position and size of the repartitioned standard area 510 and extension area 520, and outputs the reset position and size of the standard area 510 and extension area 520 to the controller 300 in step S215. The controller 300 adjusts a size of the data to be identical to the reset size of the standard area 510 having the reset position and size, and adjusts a size of the user's additional information to be identical to the reset size of the extension area 520 having the reset position and size in step S217.
The controller 300 determines whether the extension area 520 should be moved according to the reset position of the extension area 520 in step S219.
If the extension area 520 should be moved according to the reset position of the extension area 520, the controller 300 moves the extension area 520 to the reset position of the extension area 520 in step S221.
The controller 300 rotates the data displayed in the standard area 510 by the same rotation angle but in the direction opposite to the rotation direction of the wide display unit 500 in step S223.
The controller 300 determines whether the user's additional information displayed in the extension area 520 should be rotated in step S225, and if the user's additional information should be rotated, the controller 300 rotates the user's additional information by the same rotation angle but in the direction opposite to the rotation direction of the wide display unit 500 in step S227. The process then returns to step S201, and the controller 300 displays the data and user's additional information in the standard area 510 and the extension area 520, respectively.
In the example shown in FIG. 4, when the controller 300 receives from the sensor unit 250 information that the wide display unit 500 rotates 270° clockwise (or 90° counterclockwise) from the display screen shown in FIG. 4A to a display screen shown in FIG. 4B, the controller 300 rotates the data of the standard area 510. The data are rotated in a direction opposite to the rotation direction of the wide display unit 500. Also, the user's additional information displayed in the extension area 520, which includes the search window 521 and the RSS window 522, is rotated and displayed in a direction opposite to the rotation direction of the wide display unit 500.
As described above, according to the present invention, by displaying data in a standard area of the wide display unit and displaying user's additional information in an extension area of the wide display unit, the wide display unit can be effectively used.
Further, by displaying the user's additional information in the extension area of the wide display unit, an interface convenient to a user can be provided.
Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
