Description

Method for controlling frame split in mobile communication terminal

The present invention relates to a method for controlling screen division of a mobile communication terminal, and in particular, to provide a service by dividing a screen display (LCD) into a main screen and an auxiliary screen when a user wants to use two functions together on one screen. The present invention relates to a screen division control method of a mobile communication terminal.

Personal mobile phones are being developed in various ways such as cellular phones, PCS phones, satellite communication phones. In addition, his technical development is being made continuously, and even more advanced technologies are being developed, and functions and designs are being developed so that the limits of portable communication are unpredictable.

However, all research and commercialization is being made in the development of such advanced technologies, but there are problems in that mobile phones are being used as daily necessities in our daily life, and the additional functions are not easily reflected by the general public.

A commonly used mobile communication terminal includes a user information input unit for inputting user information and a display device for displaying the input information and schedule information in a visible state.

Examples of such information processing devices include digital portable telephones (cellular phones), electronic notebooks, personal digital assistants (PCS phones), and IMT-2000 (International Mobile Telecommunication 2000). Such portable mobile communication terminals usually perform user information processing and perform various functions according to a user's request. A method commonly used in the method of performing such functions is to perform an operation of a corresponding function according to a menu selection input or a shortcut key. There is a way to make it happen. This is done by assigning a menu corresponding to a specific function and then displaying a specified menu according to a specific request input so that when a user selects the menu, a predetermined function according to the selected menu is performed. Through a process to perform a predetermined function according to the menu to be performed. In addition, recently, if a function is required to be performed by the user by iconizing each menu, the corresponding icon selection is made accordingly, and the function is performed by selecting the icon accordingly. The proposed method is to further increase the convenience of.

However, as an example of various portable electronic devices displaying information through such a liquid crystal display device, the portable terminal cannot display a large amount of information at a time because only one small and medium liquid crystal panel is provided. In particular, among the mobile phones currently on the market, for example, when playing a game, only a game function is performed, and there is a problem that cannot be used in connection with a text message (or call).

In other words, if you want to watch a watch while playing a game, if you want to make a phone call while playing a game, if you want to send a text or see while listening to a song, that is, if you want to use both functions at once Provide only. In addition, since the desktop and the clock are usually output on the LCD screen, when a call comes, a small window floats on the desktop and the number is written or the number is written on the entire screen. If a character comes in during the game, the window will pop up to check the characters, and when listening to music or using other functions, the LCD window will be used for one function.

Therefore, there is a problem in that it does not show the two functions of the portable terminal together on the LCD window such as playing a call or sending a text while listening to a melody while playing a game on the portable terminal currently on the market.

On the other hand, thanks to the continuous development technology of the IT industry and the expected market of IMT-2000 business, mobile small and medium sized display devices can support e-mail service or moving image service as well as existing text / voice service to accommodate various contents in web environment. As a result, there has been a demand for larger screens and various screen realization methods in a display use environment.

However, the external technology flow of small and medium-sized mobile display devices, including portable terminals, is becoming increasingly light and thin in the condition that some simple additional services are added to existing basic services. At the bottom of the thin and thin components, the consumer's demand for convenience of mobile was the main reason, and accordingly, the development of material component technology and driving technology of the portable terminal and the development of low power consumption have been continuously made.

In view of this, the desire to enlarge the size of small and medium-sized mobile display devices, such as portable terminals, is contrary to the demand for portable miniaturization. When the display becomes large, the size / volume of the material parts and the driving unit increases accordingly. It is accompanied by a drawback, and the power consumption also increases rapidly has the drawback that leads to a reduction of the battery capacity capacity time.

Therefore, in line with the trend of light and light mobile phones, there is a need for a method that can sufficiently display necessary information while using an existing LCD screen. In particular, if a screen split function that splits the LCD screen and displays two functions at the same time is accompanied, more information may be provided to the user, which may be efficient.

The present invention has been proposed to solve the above problems, and if you want to use the two functions together on one screen of the terminal function to provide a service by dividing the screen display (LCD) into the main screen and the sub-screen It is an object of the present invention to provide a screen division control method of a mobile communication terminal.

1 is an exemplary configuration diagram of a mobile communication terminal to which the present invention is applied.

The control unit 10 of the mobile communication terminal controls the overall operation of the terminal, and at the same time controls the screen division and screen size adjustment, the screen determination method to which the operation of the menu key is applied according to the present invention. Then, control of various components provided is achieved.

The voice memory 11 stores various voice data.

The memory 12 stores an operation program and a system program of the controller 10, and the operation program and the system program are usually stored in a ROM area included therein and can be erased as necessary. Electrically erasable ROMs include EEPROM and flash memory. The memory 12 also includes RAM for temporarily storing data generated during the execution of various operating programs.

The key input unit 13 includes a plurality of numeric keys, menu keys, and function keys for performing various functions (in particular, a screen division setting key, a screen switch key for selecting an operation by a function key during screen division, a screen division release key, etc.). ), And outputs key data to the controller 10 by an external operation.

Here, the screen division setting key, the screen switch key, and the screen division release key may be separately designated, or may be designated as a hot key in addition to the basic function. For example, in the case of additional designation, the screen division setting key is # 1, the screen switch key is # 2, and the screen division release key is # 3.

There are two main ways to divide the screen. One is when the first LCD (main screen) is being used by the user (e.g. playing a game or listening to music), a call is received or a text message is sent via SMS. When the reception is received, the main screen (first LCD) is automatically divided and the sub screen (second LCD) is displayed.

The other is that the user presses the screen division setting key while the first LCD (main screen) is being used by the user (e.g. playing a game or listening to music) or in the initial menu state (no use). The sub-screen (second LCD) is displayed by forcibly dividing the screen (first LCD).

The screen division setting key may be designated as a separate basic key on the terminal, or may be additionally assigned to an existing function key. For example, the hot key as the screen division setting key can be "# 1" or the like.

The display unit 14 is a display device such as a liquid crystal display (LCD) and the like, and displays the state of the mobile communication terminal or the progress of the program under the control of the control unit 10. That is, the overall state of the mobile communication terminal and input user information are displayed.

Accordingly, the controller 10 reads the menu from the memory 12 and displays the menu on the display unit 14 in response to a user's menu display request by the key input unit 13. That is, the key input unit 13 is a conventional user information input means, and has a plurality of keys suitable for a mobile communication terminal to be applied, such as a number of numeric keys and function keys, and if there is an input of each of the provided keys, Therefore, by outputting the corresponding unique key data to the control unit 10, through the key input operation of the key input unit 13 to enter the menu display mode and selection of the menu is made. Then, the controller 10 reads the menu according to the corresponding key input from the memory 12 and displays the menu on the display unit 14.

The RF unit 15 is controlled by the controller 10 and converts a signal output from the controller 10 into a radio signal. In addition, the RF unit 15 converts the radio signal received through the antenna into a desired signal and outputs it.

The ring tone generator 16 generates a ring tone through the speaker under the control of the controller 10.

The voice processor 17 modulates the voice signal input from the microphone to convert the voice signal into voice data, demodulates the voice data input from the RF unit 15 and the voice data stored in the voice memory 11 into voice signals. Sound is output through a speaker.

2A to 2C are diagrams illustrating an embodiment of a mobile communication terminal having a screen display window according to the present invention.

When the main screen (first LCD) of FIG. 2A is forcibly divided by automatic or user selection, an auxiliary screen (second LCD) of a minimum unit appears on the main screen (first LCD) as shown in FIG. 2B. At this time, the size of the sub-screen (second LCD) can be arbitrarily adjusted as shown in FIG. 2C. As a screen control key of the sub-screen, it can be designated as a separate primary key on the terminal and a side key as an existing setting key. Or use navigation keys.

For example, referring to the operation by the side key as the screen size adjusting key, "↑" is the screen size in the up and down direction of the sub-screen (second LCD), and "↓" is the sub-screen (second LCD). ) Adjust the screen size in left and right directions. In addition, when using the navigation keys, it is possible to apply up, down, left and right (↑, ↓, ←, →) as it is. That is, while the main screen (first LCD) is divided and the sub screen (second LCD) is displayed, the size of the sub screen (second LCD) is adjusted by pressing a screen control key (side key, navigation key).

On the other hand, when the main screen (the first LCD) is divided and the sub screen (the second LCD) appears, the operation by the function keys in each screen (the first and the second LCD) can be selectively performed. This is possible by means of a switch key. That is, in the screen divided state, the operation by the menu key is based on the operation on the main screen (first LCD). If the screen switching key is pressed, the operation by the menu key is performed on the sub screen (second LCD). Switch to action. That is, when the main screen (first LCD) and the sub screen (second LCD) exist at the same time, the screen to which the operation of the menu key is applied is determined by the screen switching key. The screen switching key may be designated as a separate basic key on the terminal, or may use a screen division setting key (specified key or "# 1"). Alternatively, it may be specified in addition to an existing function key. For example, the hot key as the screen switching key can be "# 2" or the like. For example, when the screen is divided into the first and second LCDs, the operation by the menu key is operated on the main screen (first LCD), and when the screen division setting key is pressed, the operation by the menu key is activated by the sub-screen (second display). LCD).

However, while the main screen (first LCD) is being used by the user (for example, playing a game or listening to music), a call is received or a text message is received via SMS, and the main screen (first LCD) is automatically received. When the sub screen (second LCD) is divided and the sub screen is generated, the operation by the menu key may be set based on the operation on the sub screen (second LCD). Of course, even in such a case, if the screen switching key or the screen division setting key is pressed, it is obvious that the screen to which the operation by the menu key is applied is switched.

In addition, when a call is received while a main screen (first LCD) is being used or a text message is received through SMS, the main screen (first LCD) is automatically divided to generate a sub screen (second LCD). When the menu key is applied only to the sub-screen (second LCD) without the screen switching function where the action by the key can be selectively applied, and the execution of the operation on the sub-screen (second LCD) is completed (for example, call completion, text) Completed transmission and reception, etc.) The auxiliary screen (second LCD) disappears automatically and only the main screen (first LCD) remains, and a function key is operated on the main screen (first LCD).

Meanwhile, when the main screen (first LCD) and the sub screen (second LCD) are present at the same time, when the screen split release key is pressed on the screen to which the menu key is applied, the corresponding screen disappears and only the remaining screen remains. For example, when the screen division release key is pressed while the menu key is operated on the main screen (first LCD), the main screen (first LCD) disappears and the sub screen (second LCD) becomes the main screen. On the contrary, when the screen division release key is pressed while the menu key is operated on the sub screen (second LCD), the sub screen (second LCD) disappears and the main screen (first LCD) remains intact.

The screen splitting release key may be designated as a separate basic key on the terminal, or may be additionally assigned to an existing function key. For example, the hot key as the screen division release key can be "# 3" or the like.

As described above, the present invention divides the first LCD (main screen) to adjust the size of the added second LCD (secondary screen), and selects from the main screen (first LCD) and the sub-screen (second LCD). It is possible to operate by regular function keys.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention divides the first LCD (main screen), adjusts the size of the added second LCD (secondary screen), and selects the main screen (first LCD) and the auxiliary screen (second LCD). By operating by a function key, a more efficient use of the mobile phone can be exhibited.
