The present invention relates to a wireless communication terminal having a screen division control function and a method thereof, and more particularly, to a wireless communication terminal having a screen division control function which can be used independently by dividing a terminal screen (LCD), and a screen thereof. A division control method.

Personal portable terminals have been developed in various ways such as cellular phones, PCS phones, PDA phones, satellite communication phones. In addition, his technical development continues, and even more advanced technologies are being developed, and functions and designs are being developed to meet the limits of mobile communication.

However, all research and commercialization has been made in the development of such advanced technology, but there is a problem in that the portable terminal is a daily necessities of our daily life while the general public can easily carry the additional functions. That is, in the mobile terminal, in addition to the basic voice call, data communication (for example, SMS, MMS, e-mail, games, etc.), telephone number database, schedule management, personal memo, Internet search, broadcast reception, video / music playback, etc. There is an increasing demand for additional functionality.

Such a portable terminal typically includes a user information input unit for inputting user information and a display unit for displaying the input information and schedule information in a visible state.

Examples of such portable terminals include digital portable telephones (cellular phones), electronic notebooks, personal digital assistants (PCS phones, PDA phones), IMT-2000 (International Mobile Telecommunication 2000), and the like. Such portable terminals usually perform user information processing and perform various functions according to a user's request. The 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. This is done by assigning a menu corresponding to a specific function and then displaying a specified menu according to a predetermined 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. Particularly, according to the prior art, only a game function is performed when a mobile phone currently on the market, for example, is playing a game, 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 while watching a song, or if you want to use both functions at once Provide screen only.

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

Looking at the problem according to the prior art in more detail as follows.

Looking at the UI (User Interface) functions of the terminal, currently only one screen shows the content used by the user. Therefore, when a specific event (for example, receiving an SMS, receiving a call, etc.) occurs, a new screen for notifying a newly generated event is displayed on the screen before the event is generated. In this case, the screen previously used by the user disappears immediately or the event can be returned to the previous screen state after the event ends. This is because the entire screen memory allocated to the LCD is used to update the screen every second or when an event occurs.

For example, if you are editing a text on one screen and you are talking on the phone at the same time, the editing operation is interrupted and the screen showing the call appears, and the editing is possible after the call ends. This is because, if the screen memory allocated by the total screen size is used according to the prior art, it is impossible to partially compose the data in order to newly compose the data to be configured on the screen.

As described above, according to the related art, partial data configuration is difficult because all the memories must be considered in order to configure the data to be displayed on the screen, and the screen memory for storing data to be displayed on the LCD window is [full LCD size * Color Depth]. Since the number of bits] is allocated, the screen update speed is also slowed down because the screen is calculated for all screen memories as much as the LCD size when the screen is switched. In particular, the current LCD size of the terminal is becoming more and more, such a phenomenon is to be considered more.

Therefore, if the LCD screen is divided and the screen splitting function that can simultaneously display two functions on one screen is accompanied, the user can not only provide more information but also improve the updating speed of each screen. It will be efficient.

The present invention has been proposed to meet the above-mentioned requirements, and splits the terminal screen (LCD) so that each can be used independently, and at this time, a wireless communication terminal having a screen split control function to improve the update rate of each screen; Its purpose is to provide a screen division control method thereof.

Other objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

Way; And display means for displaying the data necessary for interrupt processing generated on the LCD by dividing the screen when an interrupt occurs under the control of the control means.

On the other hand, the method of the present invention is a screen division control method in a wireless communication terminal, comprising: a storing step of dividing the screen storage means, respectively storing data necessary for display for each area of the divided display (LCD) by interrupt generation; Splitting the first LCD to generate a second LCD to display data necessary for the interrupt processing when the first interrupt occurs; And a display step of reading data to be displayed on each LCD from the screen storage means and displaying the data on the LCD.

In addition, the present invention, when the second interrupt occurs, splits the first LCD or the second LCD to generate a third LCD to display the data required for the interrupt processing, and stores the data to be displayed on the third LCD screen And splitting and displaying the read-out means by the means and displaying on the third LCD.

The present invention may further include a screen returning step of automatically transitioning to a state prior to LCD automatic screen division when the first or second interrupt is released.

According to the present invention, a first LCD is divided into screens to generate a second LCD according to a user's first screen division setting request, and data to be displayed on each LCD is read from a corresponding screen storage unit and displayed on the corresponding LCD. And further comprising a first screen division and display step.

According to the present invention, according to a user's request for setting a second screen division, the first LCD or the second LCD is screen-divided to generate a third LCD, and data to be displayed on the third LCD is read by the screen storage unit. And further comprising the second screen division and display step of displaying on the third LCD.

The present invention may further comprise a screen returning step of maintaining the state before the LCD forced screen division according to the user's request for splitting the screen.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an embodiment of a wireless communication terminal having a screen division control function according to the present invention.

As shown in FIG. 1, a wireless communication terminal having a screen division control function according to an embodiment of the present invention includes a memory (at least one screen memory) that stores data necessary for display for each divided area (LCD) area generated by interruption. (12) and, when the first interrupt occurs, splits the first LCD to generate a second LCD to display data necessary for the interrupt processing, and reads data to be displayed on each LCD from the corresponding screen memory 12. The control unit 10 for controlling display on the LCD 14 and the display unit 14 for displaying the data necessary for interrupt processing generated on the LCD 14 by splitting the screen when an interrupt occurs under the control of the control unit 10. It includes.

Here, the memory 12 includes a screen memory for each screen-divided LCD. Thus, it has two screen memories in two screen divisions and four screen memories in four screen divisions.

The control unit 10 of the wireless communication terminal controls the overall operation of the terminal and at the same time achieves a screen division control function (screen division and screen size adjustment, operation of the menu key, etc.) 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. In particular, the memory 12 also includes a screen memory (RAM) for temporarily storing data generated during the execution of various operating programs.

In particular, since the screen memory for storing data to be displayed on the LCD window is allocated as much as [total LCD size * number of color depth bits], the present invention divides the screen memory into 1/2, 1/4, etc. Use 2 or 4 LCDs as if they were operating independently. By doing this, the screen update speed can be improved, and it is also possible to simultaneously perform two tasks or four tasks on one screen of the terminal UI.

Specifically, the screen memory RAM, which is transmitted to the LCD driver and stores data displayed on the screen, is allocated as much as [LCD size * number of color depth bits representing pixels]. Therefore, in the present invention, this screen memory is separately allocated to two screen memories having a size of, for example, [(LCD size / 2) * number of color depth bits representing pixels]. That is, each screen memory is divided into an 'up screen memory' for storing data to be displayed on the upper (upper) part of the divided areas on the LCD, and a 'low screen memory' for storing data to be displayed on the lower (lower) part. . Alternatively, the screen is divided into a left screen memory storing data to be displayed on the left (left) and a right screen memory storing data to be displayed on the right (right). In this case, data allocated for display is separately stored in each allocated memory (upper / lower screen memory or left / right screen memory), and the data to be stored in each memory are divided by coordinates to be located on the screen of the actual terminal. Stored. That is, when storing, the data connection list for each memory is constructed and stored in a method already implemented. Then, if the data stored in each memory (up / down screen memory or left / right screen memory) is transferred to the LCD driver by specifying the LCD area for each memory, the transferred data is updated only the partial screen of the area to which the memory belongs. Done.

Thus, since the memory to be updated is divided according to which data is displayed on the screen, only the data of the required memory need to be updated. Therefore, the speed of composing the data to be scattered on the screen is faster than using the entire LCD size, and the overall display update speed is faster. Using this method, various UI effects for the user can be used and it is possible to perform two operations at the same time. For example, the memory belonging to the LCD area being edited is configured separately for each edit, and the screen showing the call is configured in another memory and updated after each update. have.

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, when additionally specified, the screen division setting key is # 1, the screen switching key is # 2, and the screen splitting key is # 3.

Screen splitting can be divided into two types, one being the first LCD (main screen) being used by the user (for example, playing a game or listening to music) while receiving a call or receiving a text message via SMS. When the reception is received, the main screen (first LCD) is automatically divided so that the sub screen (second LCD) is displayed (see FIGS. 2B and 2C below). Alternatively, as shown in FIGS. 2B and 2C, the split screens may be equally divided as shown in FIGS. 2D and 2E without dividing the size of the split screen into a main screen and a sub screen.

The other is that the user presses the screen division setting key while the first LCD (main screen) is being used by the user (for example, listening to a game or music) or in the initial menu state (no use). The sub-screen (second LCD) is displayed by forcibly dividing the screen (first LCD). At this time, the size of the split screen may be equalized as shown in FIGS. 2D and 2E.

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). The display unit 14 displays the state of the wireless communication terminal or the progress of the program under the control of the control unit 10. That is, the overall state of the wireless 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 according to the 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 wireless 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 2E are exemplary diagrams of screen division control in a wireless communication terminal according to the present invention.

When the first LCD (main screen) of FIG. 2A is forcibly divided by automatic or user selection, the second LCD (secondary screen) of the minimum unit appears on the first LCD (main screen) as shown in FIG. 2B. Alternatively, the first and second LCDs may be equally divided as shown in FIGS. 2D and 2E.

At this time, the size of the second LCD (secondary screen) can be arbitrarily adjusted as shown in FIG. 2C or the size of the second LCD divided evenly as shown in FIGS. 2D and 2E can be arbitrarily adjusted. It can be designated as a separate primary key on the screen, and a side key or a navigation key as an existing setting key can also be used.

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

On the other hand, when the first LCD is divided and the second LCD is displayed, the operation by the function keys on each screen (the first and the second LCD) can be selectively performed, which is possible by the screen switching key. That is, in the screen-divided state, the operation by the menu key is based on the operation on the first LCD. If the screen switching key is pressed, the operation by the menu key is switched to the operation on the second LCD. That is, when the first LCD and the second LCD are present at the same time, the screen to which the operation of the menu key is applied is determined by the screen switch key. The screen switching key may be designated as a separate basic key on the terminal, or may use a screen splitting setting key (specified key or "# 1"). Alternatively, it can 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 split into the first and second LCDs, the operation by the menu key is operated on the first LCD, and when the screen division setting key is pressed, the operation by the menu key is switched to the operation on the second LCD. You can do that.

However, while the 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 through SMS, so that the first LCD is automatically divided and a second LCD is generated. In this case, the operation by the menu key may default to the operation on the 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 first LCD is being used or a text message is received through SMS, the first LCD is automatically divided so that a second LCD is generated. Without the function, the menu key is applied only to the second LCD, and when the operation is completed on the second LCD (for example, call completion, text transmission completion, etc.), the second LCD disappears automatically and only the first LCD remains. The function keys are activated on the LCD.

On the other hand, when the first LCD and the 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 split release key is pressed while the menu key is operated on the first LCD, the first LCD disappears and the second LCD becomes the main screen. On the contrary, if the screen split release key is pressed while the menu key is operated on the second LCD, the second LCD disappears and the first LCD remains intact.

The split screen 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 can divide the first LCD evenly to produce a second LCD, or divide the size of the second LCD evenly, and can arbitrarily adjust the size of the added second LCD, Operation by an optional function key on the second LCD is possible. In this case, in particular, data displayed on each LCD may be stored for each screen memory, and the display update speed may be improved by updating only the data of the required memory.

In the LCD splitting control method described above, when the first LCD is divided and the second LCD is differentially displayed (see FIGS. 2B and 2C), when another interrupt occurs, the first LCD is divided to have the same size as those of FIGS. 2B and 2C. The third LCDs may be output on the top, bottom, left, and right sides of the second LCD, and when another interrupt occurs while the first to third LCDs are displayed, the fourth LCD of the same size may also be output on the top, bottom, left, and right sides of the third LCD.

In addition, when the first LCD is divided and the second LCD is evenly displayed (see FIG. 2D), when another interrupt occurs, the first LCD is divided equally to the left and right to output a third LCD having the same size as the first LCD. In addition, when another interrupt occurs while the first to third LCDs are displayed, the second LCD is equally divided left and right to output a fourth LCD having the same size as the second LCD.

In addition, when the first LCD is divided and the second LCD is evenly displayed (see FIG. 2E), when another interrupt occurs, the first LCD may be divided equally up and down to output a third LCD having the same size as the first LCD. In addition, when another interrupt occurs while the first to third LCDs are displayed, the second LCD may be divided equally up and down to output a fourth LCD having the same size as the second LCD.

3 is a flowchart illustrating a screen division control method in a wireless communication terminal according to the present invention.

First, the first LCD is automatically divided when an interrupt occurs such as receiving a call or receiving a message (SMS or MMS, e-mail, etc.) during a standby screen or a task (message preparation, game, music playback, etc.) (301). To form a second LCD (304).

Alternatively, the first LCD may be forcibly divided to generate a second LCD by the user's selection (by the screen division setting key) (303).

That is, when the first LCD is forcibly divided by automatic or user selection (304), the second LCD (secondary screen) of the minimum unit appears on the first LCD as shown in FIG. 2B, or as shown in FIGS. 2D and 2E. The 1 LCD is divided so that the sizes of the first LCD and the second LCD are evenly displayed.

As described above, when the first LCD is divided so that the second LCD is evenly or differentially displayed 304, an operation by a function key on each screen (first and second LCDs) may be selectively performed (306). This is enabled by the screen switch key (305). That is, in the divided screen state (304), the operation by the menu key is based on the operation on the first LCD, and if the screen switching key is pressed (305), the operation by the menu key is the operation on the second LCD. Is switched (306). That is, when the first LCD and the second LCD are present at the same time (304), the screen to which the operation of the menu key is applied is determined by the screen switching key (305, 306).

However, while the 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 through SMS, so that the first LCD is automatically divided and a second LCD is generated. In the case 304, the operation by the menu key may default to the operation on the second LCD. Of course, even in this case, if the screen switch key or the screen division setting key is pressed (305), it is obvious that the screen to which the operation by the menu key is applied is switched (306).

In addition, when a call is received while a first LCD is being used or a text message or the like is received through SMS, and the first LCD is automatically divided to generate a second LCD (304), an operation by a menu key is selectively applied. The menu key is applied to the second LCD without any screen switching function, and the second LCD disappears and only the first LCD remains when the operation on the second LCD is completed. The function key may be configured to operate on the first LCD.

On the other hand, when the first LCD is divided so that the second LCD appears evenly or differentially (304), the size of the second LCD can be arbitrarily adjusted as shown in FIGS. 2C, 2D and 2E (308). As a screen control key, a separate basic key may be designated on the terminal, and a side key or a navigation key as an existing setting key may be used.

In the case where the first LCD is divided so that the second LCD is equally or differentially displayed (304), 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 split release key is pressed while the menu key is operated on the first LCD, the first LCD disappears and the second LCD becomes the main screen. On the contrary, if the screen split release key is pressed while the menu key is operated on the second LCD, the second LCD disappears and the first LCD remains intact.

As described above, the present invention can divide the first LCD evenly to produce a second LCD, or divide the size of the second LCD evenly, and can arbitrarily adjust the size of the added second LCD, Operation by an optional function key on the second LCD is possible. In this case, in particular, data displayed on each LCD may be stored for each screen memory, and the display update speed may be improved by updating only the data of the required memory.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

In the present invention as described above, since the screen memory is divided and used, only the area to which the data requiring screen updating belongs is configured as a list, so that the amount of calculation is reduced and the update speed is increased, and the area is divided in the entire LCD. There is an effect that can be used in parallel with at least two functions of.
