Description:
This is a Continuation of prior application Ser. No. 09/967,996, filed on Oct. 2, 2001, which claims priority to Korean Application No. 2000-58667, filed on Oct. 6, 2000. The entire disclosure of the prior applications is considered as being part of the disclosure of this application and is hereby incorporated by reference herein. 
    
    
     BACKGROUND  
      1. Field  
      The present invention relates to a mobile telephone, and more particularly, to a method of displaying menus on a screen of a mobile telephone using a scroll technique.  
      2. Background  
      In general, a mobile telephone of today provides various types of supplemental functions as well as a basic call making/receiving function. Such supplemental functions can be divided into two groups: one group of menu functions and the other group of memory functions. Some of the typical examples of the menu functions are telephone number directories, message management, calling options, voice dialing, electronic organizer, phone manager, and many more. Storing, searching, and modifying telephone numbers are often regarded as typical examples of the memory functions.  
      In order to use any of such menu functions and/or memory functions, some mobile telephones additionally include a menu key for accessing to the menu or bar functions, a search key for searching a telephone number, and/or a navigation key for various uses. When a user selects a menu from a menu list by pressing down a menu key or a navigation key of a mobile telephone, the LCD (liquid crystal display) of the mobile telephone displays a text or graphic corresponding to the selected menu. The old mobile telephones displayed only selected menus, and the user was able to view and select a desired menu by using the up and down keys.  
       FIG. 1  is a typical system block diagram of a mobile telephone. As it is shown in  FIG. 1 , the mobile telephone includes a controller  10 , a radio data processor  20 , a voice input/output element  30 , a display element  40 , a memory  50 , a key input element  60 , and a power supply element  70 . The controller  10  controls each part of the mobile telephone, and the radio data processor  20  receives/transmits the data from/to a base station. The voice input/output element  30  inputs the user&#39;s voice signal and outputs the voice signal of the other party. Next, the display element  40  (i.e., LCD) displays various states of the telephone and search information, and the memory  50  stores data for various programs and many more. The key input element  60  inputs various commands for searching a desired number or information, and the power supply element  70  provides required electricity to each part of the telephone.  
       FIG. 2  illustrates sample LCD displays of a mobile telephone showing its menu configuration according to the related art. When a user accesses the top menu list by pressing a menu key or navigation key, the screen shown in  FIG. 2A  will be displayed on the LCD. It initially displays top menus for Phone Directory (1), Messages (2), and Call Options (3). Each top menu includes a corresponding text and picture indicative of each menu. The screen showing the top menu list further includes the order number (1,2, and 3) of each top menu below each picture and arrow signs (←,→) for displaying other top menus not shown in the previous screen. Since the LCD can show only a limited number of top menus,  FIG. 2B  can be displayed using up/down keys of the mobile telephone.  
      When the user selects a desired top menu from the top menu list, a sub menu list of the selected top menu will be displayed as shown in  FIG. 3 .  FIG. 3A  illustrates a sub menu list of the Phone Directory top menu and an Outgoing Numbers sub menu. Similarly,  FIG. 3 .B illustrates a sub menu list of the Messages top menu and an Incoming Messages sub menu. As it is shown in both figures, the sub menu list of a top menu (Phone Directory or Messages) shows each sub menu title with a corresponding order number. Since the sub menu list displays only the sequence number of each sub menu, a user is not able to know the total number of all the sub menus. In addition, the user must press down the sequence number of a desired top or sub menu in order to select the menu. These will greatly inconvenience a mobile telephone user.

     DETAILED DESCRIPTION OF THE INVENTION  
      Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.  
       FIG. 4  illustrates displays of a mobile telephone according to a first embodiment of the present invention. It includes a first display ( FIG. 4A ) illustrating a Message menu, an intermediate display ( FIG. 4B ) showing both parts of the Messages menu and its Call Option menu adjacent to the Messages menu, and finally a third display entirely showing the Call Option menu. A telephone user must scroll in order to move from FIG. A to FIG. C or from FIG. C to FIG. A by pressing a proper key. Each display shown in  FIG. 4  includes a top page number P 1  indicating the order number of a top menu currently being displayed, a plurality of boxes P 2  indicating the total number of the existing top menus, and a blinking box P 21  indicating which top menu among all the existing top menus is being currently being displayed.  
      In other words, the screen initially displays a Message menu having a graphical illustration and a text as shown in  FIG. 4A . When the user presses down a navigation key or enters a top menu number in order to move to a Call Option top menu adjacent to the initial menu, the screen displays the intermediate figure ( FIG. 4B ) including both of the right half portion of the Message top menu and the left half portion of the Call Options top menu. When the user presses down the navigation key or enters the top menu number again to move to the next menu, the screen will display the entire Call Option top menu. Even though  FIG. 4  illustrates the menu scrolls in a left-right direction only as an example, the user driven menu scrolls can be performed in the up/down or diagonal directions as well.  
      Each of  FIG. 4A ,  FIG. 4B , and  FIG. 4C  includes the sequence number P 1  of a current top menu being displayed, a plurality of boxes P 2  indicating the total number of the top menus, a blinking box P 21  indicating the current top menu being displayed. For example, the Message menu being displayed in  FIG. 4A  and  FIG. 4B  is a second top menu among a total of nine top menus. Therefore, P 1  indicates 2, and there are nine boxes P 2  indicating the total number of the top menus. In addition, the second box is blinking since the Message menu is a second top menu. The blinking box P 21  and other boxes indicating a current top menu are not limited to what is shown in  FIG. 4 . They can be shown in a different form or color.  
      In addition, when it is desired to move to a top menu not adjacent to the current top menu, the user can simply press down a key corresponding to the sequence number of the desired top menu. In this case, the screen will not display an intermediate transitional figure. Instead, it will directly display an entire requested top menu.  
       FIG. 5  illustrates displays of a mobile telephone according to a second embodiment of the present invention. Once a desired top menu and a first sub menu are selected from  FIG. 4 , the screen of the mobile telephone will display the second sub menu list of the selected first sub menu as shown in  FIG. 5A . A cursor moves up and down in order to select a desired sub menu. When a user presses a key to move a cursor from an original sub menu to an adjacent sub menu (from C 3  to C 4 ), the cursor includes the bottom half of the original sub menu text (Fax Messages) and the top half of the adjacent sub menu text (Delete Messages) as shown in  FIG. 5C . If the user presses the key to move the cursor again toward the adjacent sub menu text C 4 , the cursor will indicate only the adjacent sub menu text (Delete Messages) as shown in  FIG. 5D .  
      In addition, each figure of  FIG. 5  has a set of numerals P 3 , each of which represents the current top menu number, current sub menu number, and current cursor location. For example, each numeral of 2-1-3 represents a second top menu (Messages), a first sub menu (Incoming Messages) of the second top menu selected, and a third item (Fax Messages) of the first sub menu of the second top menu currently being selected by the cursor. Dashes are inserted between the numerals of P 3  in order to distinguish each of them. By using the set of numerals P 3 , the user can see which top menu and/or sub menu he or she is currently viewing in a more compact manner. Therefore, the user is able to access to any desired menu even without viewing the menu list.  
      Furthermore, each display shown in  FIG. 5  includes a bar P 4  having a length indicative of the total number of the items included in a sub menu. A point indicator P 41  located on the bar P 4  represents the current location of the cursor. For example, let&#39;s assume that there are five items of a Messages sub menu as shown in  FIG. 5A  and the length of the bar P 4  is one inch. If the cursor is currently on the Fax Messages item (third item) as shown in  FIG. 5A , the distance between the point indicator P 41  and the top end of the bar P 4  can be ½ inch.  
      In conclusion, an improved user interface of a top menu list display is achieved by displaying and selecting a top menu with a scroll technique and by including a numerical and graphical menu indicator indicative of the current menu location in a menu tree. Similarly, the item list display of a selected sub menu includes a cursor scrolling up and down for selecting a desired item in a friendly manner, and it also includes a numerical and graphical presentation indicative of the current cursor location in a menu tree.  
      The forgoing embodiments are merely exemplary and are not to be construed as limiting the present invention. The present teachings can be readily applied to other types of apparatuses. The description of the present invention is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
