- the open/close state of the cover 20 is detected and then transmitted from the cellular phone to the server 36 .
- the server 36 transmits to the cellular phone the display that corresponds to the screen redrawing command and the exposed screen size.
- the server 36 transmits to the cellular phone the display information corresponding to the large-sized screen, and the display device 30 of the cellular phone redraws the screen by the display information corresponding to the large-sized screen to terminate the program.
- the cellular phone judges whether the display information transmitted from the server 36 is the display information predetermined by the user. If it is judged that the transmitted display information is not the display information predetermined by the user, the transmitted display information is considered as the general information corresponding to the large-sized screen, and the server 36 transmits to the cellular phone the display information corresponding to the small-sized screen. The cellular phone redraws the screen of the exposed display device 30 by the received display information corresponding to the small-sized screen, and then the program is terminated.
- the transmitted display information includes the information predetermined by the user
- the exposed screen is redrawn by rearranging items of the menu in a manner that the information predetermined by the user is preferentially displayed.
- the cellular phone displays the information on the exposed screen of the display device 30 according to the open/close state of the cover 20 so that the user can actually view the information. This process can be performed by a simple contact with a pen using the touch panel.

Specifically, most cellular phones currently on the market have a keypad which is provided on the front surface of a main body of the cellular phone and in which number keys, character keys, and function keys for performing various built-in functions are arranged.
However, in order to perform the above-described Internet service and web browser function, the cellular phone is required to have more keys in addition to the above-described number keys, character keys, and function keys. Since the above-described keys and a display device are arranged together on the front surface of the main body of the cellular phone, there are restrictions for arranging more keys in addition to the above-described keys on the front surface of the main body.
Meanwhile, since the display device (mainly, a liquid crystal display (LCD)) of the cellular phones currently on the market generally has a size corresponding to about 5 word lines, which is inadequate for performing an Internet search, chatting, cyber purchasing, etc. In other words, the cellular phones require larger LCDs. However, such an increase makes it more difficult to secure more space for the arrangement of keys for supporting the Internet service on the front surface of the main body.
Meanwhile, flip-type cellular phones having a large-sized screen have been popularized so that connection to the Internet or management of personal information can be implemented using the cellular phone. However, since the display device of the cellular phone is small, it is not suitable for the browser. Also, the method of searching information and the method of defining documents that define the information of the cellular phones are different from those used in general computers.
As a result, browsers for supporting a small screen size and monochromatic screen have been newly developed. A UP-type browser, that is one among such browsers, is built in a cellular phone so as to use the Internet through the cellular phone. For example, the UP browser of 3.1 Version for searching the Internet through the cellular phone can be manipulated through the keypad corresponding to the 3.1 Version. Accordingly, a user should manipulate the keypad corresponding to the 3.1 Version in case that he/she searches the Internet through the browser or uses a pocketbook function built in the cellular phone.
As described above, the related art cellular phone has a disadvantage that the user needs to open the flip cover and then press the keypad of the main body if he/she wishes to select the displayed information when the flip cover is initially closed, causing an inconvenience for the user. Also, in order for the user to view the displayed information hidden by the closed flip, he/she needs to open the flip cover.
The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.

The invention will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein:
The cellular phone according to a preferred embodiment of the present invention has three keypads, and a display device provided on a main body, the display device having a larger size than that of the related art cellular phones. Preferably, the cellular phone according to a preferred embodiment of the present invention has built-in function blocks and software for the mobile communication service, and built-in function blocks and software for the mobile Internet service. Further, the cellular phone according to a preferred embodiment of the present invention has a built-in wireless application protocol (WAP) browser for the mobile Internet service.
As shown in FIGS. 3A and 3B , the cellular phone includes a main body or housing 10 and a cover 20.
The main body 10 includes a display device 30 and a keypad 50 preferably having an area smaller than that of the display device 30, both of which are provided on the front surface of the main body 30.
The cover 20 is preferably rotatably mounted on the main body 10, and has a front keypad 60a and a rear keypad 60b provided on the front and rear surfaces thereof, respectively. In the first embodiment, the cover 20 has an area smaller than that of the front surface of the main body 10, and thus, when the cover 20 is in a close state, a portion of the display device 30, i.e., an upper portion 30a of the display device 30 in the preferred first embodiment of the present invention, is exposed or revealed.
In FIG. 3B , the cover 20 may be the cover of the folder-type cellular phone although FIG. 3B illustrates a flip-type cellular phone. The main body 10 has a relatively large display (e.g., a liquid crystal display (LCD)), and the cover 20 rotates on the main body 10. For this rotation, a hinge in the form of a joint is provided between the cover 20 and the main body 10.
The cover 20 is opened and closed by the operation of a cam connected to the hinge. The hinge converts a rotary motion into a straight motion, and the cover 20 is opened and closed by the operation of the hinge.
Meanwhile, the flip-type cover 20 may be a general flip type or a flip-up type. This flip-type cover is connected to the hinge by a hinge shaft in the same manner as the folder-type cellular phone, and a cam is connected to the hinge so that the flip-type cover 20 is smoothly opened and closed. Also, a spring is provided to give a constant force when the flip-type cover 20 is opened and closed.
In the preferred first embodiment of the present invention, an open button 40 is provided on the side or any other suitable location of the main body 10 for opening and closing the cover 20. If the open button is pressed, the cover 20 is opened with respect to the main body 10 by the cam, hinge, and/or spring. The open button 40 may further perform the function of starting and ending the connection to the mobile communication service or mobile Internet service as well as the function of opening and closing the cover 20.
Meanwhile, a signal transmission for a telephone call is performed by pressing a SEND key arranged on the front keypad 60a after inputting a telephone number by the keys provided on the front surface of the cover 20. The signal transmission may be also performed by pressing the open button 40. If the open button 40 is pressed, a call signal corresponding to the inputted telephone number is transmitted to the opposite party, and the telephone call to the opposite party becomes possible.
Meanwhile, considering that the keys provided on the front surface of the cover may perform unwanted operations due to their exposure, the SEND key for the signal transmission may be arranged on the main body 10, or on the rear surface of the cover 20 or other appropriate location
As described above, the cover 20 (or lower cover 20b of FIG. 3C ) of the cellular phone according to the preferred first embodiment of the present invention has an area smaller than that of the main body 10. Accordingly, if the cover 20 is in the close state, only a portion of the display device 30, i.e., the lower portion 30b of the display device 30, is hidden by the cover 20. Thus, even when the cover 20 is in the close state, the user can use the mobile communication service or Internet service through the exposed upper portion 30a of the display device.
Specifically, in the cellular phone according to the first embodiment of the present invention, the area of the cover 20 is determined in a manner that the upper portion 30a of the display device 30 is exposed even if the cover 20 is closed. That is, in a state that the cover 20 is closed, the display device 30 is not entirely hidden by the cover 30.
On both surfaces of the cover 20, i.e., on the front and rear surfaces of the cover 20, are provided a plurality of keys (or buttons) preferably having different uses. Specifically, when the cover 20 is closed, the upper portion 30a of the display device 30 is exposed as shown in FIGS. 3B and 3C , and keys 1 required for transmission/reception of telephone numbers, which include the keys for inputting numbers and characters, are arranged on the front keypad 60a provided on the front surface of the cover 20. Accordingly, it is possible to perform the mobile communication even in a state that the cover 20 is closed.
A plurality of keys for inputting numbers and characters are arranged on the rear keypad 60b that is provided on the rear surface of the cover 20 (or lower cover 20b). Here, when the cover 20 is opened, the above-described keys become a power-on state, and this enables an additional data storage function such as the storage of telephone numbers required for the mobile communication to be performed. Also, keys for using the Internet service are arranged on the rear surface of the cover 20.
Referring to FIGS. 3A to 3C, the display device 30 that has an area larger than that of the display device of the related art cellular phone is mounted on the main body 10 of the cellular phone. As indicated as a dotted line in FIG. 3B , the display device 30 is divided into the upper portion 30a and the lower portion 30b. Only the upper portion 30a is exposed when the cover 20 is closed, while the display device 30 including the upper portion 30a and the lower portion 30b is wholly exposed when the cover 20 is opened. Also, on the keypad 50 provided under the display device 30 are arranged keys such as direction keys, multi-key, SEND key, and END key. The keys arranged on the first keypad 50 may be used for both the mobile communication and the Internet service.
In summary, the keys for the mobile communication are arranged on the front keypad 60a, and the keys for both the mobile communication and the Internet service are arranged on the rear keypad 60b and the keypad 50. As described above, the front keypad 60a is in the power-on state when the cover 20 is closed, and the keypad 50 and the rear keypad 60c are in the power-on state when the cover 20 is opened.
The above-described keys include various keys for the Internet service such as the WAP browser for using the Internet service. As the keys for the Internet service, there exist a page-up key, page-down key, hot key H1 for searching the uniform resource locator (URL) of the most preferable web site, and a hot key H2 for searching details of the web site previously connected. These hot keys H1 and H2 may be used for various other purposes.
Meanwhile, the display device 30 is in the power-on or power-off state in dependence upon the position of the cover 20. Specifically, if the cover 20 is opened, both the lower portion 30b and the upper portion 30a, which are divided by the dotted line as shown in FIG. 2B , are in the power-on state. If the cover 20 is closed, only the upper portion 30a is in the power-on state. Alternatively, the upper portion 30a and lower portion 30b may be in a power-on state when the cover is closed.
Referring to FIG. 4 , the cellular phone transmits information on the open/close state of the flip to the external server 36 through an internal browser (i.e., built in the mobile Internet service module 33). The server 36 receives the information on the open/close state of the cover 20, and provides the corresponding information. The server 36 includes the database 36b for storing the information and the browser client 36a. The browser client 36a receives from the cellular phone the information on the open/close state of the cover 20, and reads out the corresponding information from the database 36b in accordance with the received information. The information read out from the database 36b is provided to the cellular phone. The open/close state of the cover 20 (of the flip type or folder type) is detected by a browser application program such as the UP-browser 3.1.
In the embodiment of the present invention, the browser application program assigns a specified region for indicating the size of the display device (for example, LCD) in a data header portion when starting the browser. Specifically, in case that the cover 20 is opened, it is indicated as ‘0’, and in case that the cover 20 is closed, it is indicated as ‘1’. These ‘0’ and ‘1’ correspond to the size of the exposed screen of the display device 30.
The open/close state of the cover 20 can be processed as an event. In this case, whenever the corresponding event is produced, the corresponding information is transmitted to the browser client 36a. The browser client 36a recognizes the information on the size of the exposed screen from the header of the information transmitted from the cellular phone, and transmits to the cellular phone the information corresponding to the recognized information.
In case the cover 20 is opened, the browser client 36a reads out the information that corresponds to the size of the full screen from the database 36b, and transmits the readout information to the cellular phone. In case that the cover 20 is closed, the browser client 36a reads out the information that corresponds to the size of the exposed portion of the screen from the database 36b, and transmits the readout information to the cellular phone.
Meanwhile, when the information on the open/close state of the cover 20 is changed, the browser client 36a transmits the information corresponding to the screen size to the cellular phone along with a screen redrawing command.
The cellular phone redraws the contents of the screen in accordance with the screen redrawing command and the information transmitted from the server 36. If the cover 20 is in the close state, the cellular phone reconstructs the information according to the user's setting, and displays the reconstructed information on the exposed upper portion 30a of the display device 30. The user can predetermine the specified information included in a user selection menu such as a browser home or browser menu built in the cellular phone as a frequently used menu.
Meanwhile, in case that the cover 20 is closed, the cellular phone rearranges the transmitted information so that the contents (e.g., menu) predetermined by the user are preferentially displayed on the screen of the display device 30 among the information transmitted from the server 36. Accordingly, all the menu or menus predetermined by the user can be displayed on the exposed portion of the screen of the display device 30. When any one among the displayed menus is selected by the user, the server 36 transmits the information corresponding to the size of the exposed portion of the screen of the display device 30 (e.g., LCD), and thus all the transmitted information can be displayed on the exposed screen portion of a small size.
A touch panel may be installed on the surface of the display device 30 (for example, LCD). Through this touch panel, the user can select a desired one among the displayed menus. In this case, the user can select the desired menu without using the above-described keypads.
The UP-browser may have a problem in that it may not support the touch panel. This problem can be solved by first extracting the coordinate values corresponding to the information displayed on the display device 30. When the user selects a specified position through the touch panel, the coordinate values corresponding to the position are provided to the browser client 36a in the server 36. Accordingly, the same effect as the input of data through the keypad can be obtained through the touch panel. As a result, the user can freely use the Internet through the window of a small size even in case that the cover is closed, without inputting data through the keypad.
The present invention has various other advantages. For example, since the size information of the exposed display device 30 is always located on the header portion of the data transmitted from the cellular phone to the server 36, the display information that corresponds to the size of the exposed display device 30 is provided from the server 36 to the cellular phone. Thus, the compatibility between the cellular phone having a large-sized screen of the display device 30 and the cellular phone having a small-sized screen of the display device 30 can be maintained.
If the cover 20 is opened, the server 36 transmits to the cellular phone the display information corresponding to the large-sized screen, and the display device 30 of the cellular phone redraws the screen by the display information corresponding to the large-sized screen to terminate the program.
If the cover 20 is closed, the cellular phone judges whether the display information transmitted from the server 36 is the display information predetermined by the user. If it is judged that the transmitted display information is not the display information predetermined by the user, the transmitted display information is considered as the general information corresponding to the large-sized screen, and the server 36 transmits to the cellular phone the display information corresponding to the small-sized screen. The cellular phone redraws the screen of the exposed display device 30 by the received display information corresponding to the small-sized screen, and then the program is terminated.
Meanwhile, if the transmitted display information includes the information predetermined by the user, the exposed screen is redrawn by rearranging items of the menu in a manner that the information predetermined by the user is preferentially displayed. In other words, the cellular phone displays the information on the exposed screen of the display device 30 according to the open/close state of the cover 20 so that the user can actually view the information. This process can be performed by a simple contact with a pen using the touch panel.
In the first preferred embodiment of the present invention, the cellular phone is taken as an example, but the present invention can be applied to cases that require the compatibility among communication devices having different screen sizes such as IMT2000, TRS, PDA, etc.
As described above, the external server having the database provides to the cellular phone display the information suitable for the exposed screen size of the display device in accordance with the open/close state of the cover of the cellular phone. Accordingly, the display information is displayed on the display device so that it matches the size of the exposed screen, and the information predetermined by the user is preferentially displayed on the display device.
Further, the user can input necessary command information to the cellular phone through the touch panel instead of the keypad. According to the present invention, the information desired by the user can be displayed on the display device irrespective of the open/close state of the cover, and the compatibility among the communication devices having different sizes of screen.
Referring to FIGS. 7A and 7B , the cellular phone includes a main body or housing 100 and a cover 200.
The main body 100 includes a display device 300 and a keypad 400 preferably having an area smaller than that of the display device 300. The cover 200 is rotatably mounted on the main body 100, and has a front keypad 500 and a rear keypad 600 provided on the front and rear surfaces thereof, respectively, and a window 700 formed on an upper portion thereof. The cover 200 has an area almost the same as that of the front surface of the main body 100, and thus when the cover 200 is in the close state, a portion of the display device 300 is exposed through the window 700. The window 700 is preferably a transparent material such as a plastic or glass, or may assume an open form. The reference numeral 800 denotes the open/send/end button as in the preferred first embodiment.
The cellular phone of the preferred second embodiment is similar to that of the first embodiment except that the cover 200 has almost the same area as the front surface of the main body 100, and the window 700 is provided on the upper portion of the cover 200. Accordingly, the detailed explanation thereof will be omitted.
As described above, the cellular phone according to the preferred first and second embodiments of the present invention can perform the mobile communication service and the mobile Internet service as well. Further, since the cellular phone according to the present invention has several keypads, it can support the Internet service that require a number of buttons (or keys). Especially, several hot keys for the user's convenience during the Internet connection are provided on the cellular phone, and thus the user can easily access the Internet through the WAP browser.
