Therefore, the memory 114 stores control data according to the present invention.

The key input unit 115 is composed of only the basic keys required for the mobile communication terminal. This will be described with reference to FIG. 2. 2 is an external view of a mobile communication terminal according to an embodiment of the present invention. Referring to the configuration of the key input unit 115 of the configuration of Figure 2, the call key (SEND) 115a for making a call, the end key (END 115b) and the function keys (115c, 115d) for performing a predetermined function This key is composed of a minimum of function keys for the convenience of use, and therefore may be configured to be smaller than the number of keys shown in FIG. It can also consist of more than the number of keys.

The display unit 116 displays the operation state of the mobile communication terminal, the remaining power level, the received electric field strength, and the like. In addition, according to the present invention, when there is an input of a jog dial, a numeric key is shown according to a key input of the jog dial, and a shade is displayed on a corresponding number or shaded on a character according to the input of a jog dial. In case of dialing or text editing, the display device has an area for displaying the input character. This configuration will be described below with reference to FIG. 2. First, when a predetermined function is selected, the selected function is displayed, and a menu / keyboard area 116a for displaying menus according to the selected function, and a text display area 116b for displaying a text to be edited, such as dialing or text editing, are displayed. And an icon display area 116c for displaying a fixed icon.

The jog dial 117 is composed of a movement signal generator 117a for generating a cursor movement signal and a selection signal generator 117b for generating a selection signal. The movement signal generator 117a of the jog dial 117 rotates to the left or the right by the user and generates a signal for requesting movement of a cursor for displaying the movement of the menu displayed on the menu / keyboard area. 111). In addition, the selection signal generator 117b generates a signal requesting selection of a character or number at the cursor position and outputs the signal to the controller 111.

3 is a control flowchart of inputting a numeric key according to an input of a jog dial according to an embodiment of the present invention. Hereinafter, a control process at the time of input of a numeric key according to the input of a jog dial according to the present invention will be described in detail with reference to FIGS. 1 to 3.

The controller 111 maintains the standby state in step 200. In this case, the standby state refers to a state of checking a paging signal and receiving a pilot signal received from a base station, and simultaneously checking whether a key is input from a user. The control unit 111 maintains the standby state in step 200 and proceeds to step 202 to check whether a jog key is input from the jog dial 117. The jog key refers to both the movement signal generator 117a and the selection signal generator 117b, and any signal may be input. The controller 111 proceeds to step 204 when the jog key is input and maintains the standby state of step 200 when the jog key is not input. Here, in the case of a flip type mobile communication terminal instead of inputting a jog key, it may be configured to recognize the opening of the flip and proceed to step 204.

When the controller 111 proceeds from step 202 to step 204, the controller 111 reads the menu data stored in the memory 114 and displays it on the display unit 116. In this case, the display displays an icon on the fixed icon area 116c of FIG. 2 and a menu on the menu / keyboard area 116a. In this case, when the menus are provided in the fixed icon area 116c, only the fixed icon area 116c is displayed, and the cursor is displayed on a menu such as a number plate. As described above, the user may be configured to display a currently selectable icon displayed by using a shadow on a corresponding menu in addition to the cursor.

When the controller 111 performs the display of step 204 and proceeds to step 206, the controller 111 checks whether the jog dial of the movement signal generator 117a of the jog dial 117 is rotated to the left. If the signal for the left turn is received as a result of the test, the process proceeds to step 208, and if the signal for the left turn is not received, proceeds to step 210. First, when the controller 111 proceeds to step 208, the controller 111 moves the cursor or shades from the first displayed menu to the left menu for display. And saves the moved state. After the display is performed as described above, the process proceeds to step 204. If the menu is the first menu, that is, the left menu does not exist, the menu moves to the last menu. In detail, if there are five types of menus and each menu is 1, 2, 3, 4, and 5 in order, the movement to the left is performed as follows. The menu continuously moves in the order of "1 → 5 → 4 → 3 → 2 → 1 → 5 →…”.

In contrast, when the controller 111 proceeds to step 210, the controller 111 checks whether the jog key rotates to the right. If the jog key rotates to the right as a result of the test, the process proceeds to step 212, and if not, the process proceeds to step 214. In step 212, the controller 111 sequentially moves the menu to the fixed menu area 116c in the right direction. If this movement is described by matching the left rotation, the movement sequence is performed as follows. The menu moves in the order of "1 → 2 → 3 → 4 → 5 → 1 → 2 →…”. The controller 111 proceeds to step 204 to wait for the next key input.

In contrast, if the process proceeds from step 210 to step 214, the controller 111 checks whether a selection signal is received. Here, the selection signal is a case where a key input of the selection signal generator 117b is present. Accordingly, when the selection signal is received, the controller 111 proceeds to step 216. The controller 111 checks whether the number plate is selected in step 216. The controller 111 proceeds to step 218 when the number plate is selected, and proceeds to step 224 when the number plate is not selected. If the number plate is not selected, the control unit 111 performs a check in step 224 or later to determine which menu of the menus is selected. In the control flowchart of FIG. 3, it is assumed that the number plate is selected.

When the number plate is selected, the controller 111 proceeds to step 218 and displays the number plate on the menu / keyboard area 116a as shown in FIG. 2. The cursor is displayed on the first digit of 1. In response to the signal received from the jog dial 117, the cursor is moved to the left or the right through the same process as in steps 206 to 212. ) Are displayed continuously. The control unit 111 performs this display in step 218 and proceeds to step 220 to check whether a dialing request signal is received. If the dialing request signal is received, the controller 111 proceeds to step 222. If the dialing request signal is not received, the controller 111 continues with step 218. Here, the dialing signal refers to a case in which the call key 115a is input. When the call key is input, the process proceeds to step 222 to perform a general dialing process.

Unlike step 216 to step 224, it is checked whether the selected menu is a dial. If the dial is selected as the test result, the process proceeds to step 226. Otherwise, the process is performed after step 226. When the dial is selected in step 224, the control unit 111 makes an input through the same process as selecting a number in step 218 for a character in step 226.

As described above, the key pad can be reduced by configuring the numeric keys and keys performing various functions in the mobile communication terminal using the jog dial, and thus, the size of the display unit can be extended. In addition, there is an advantage that it is easy to add special characters by changing the software because the key is not used.
