CROSS REFERENCE TO RELATED APPLICATION

Pursuant to 35 U.S.C. §119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2005-0089298, filed Sep. 26, 2005, the contents of which are hereby incorporated by reference herein in their entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mobile communication terminal and, more particularly, to a method for moving data between two or more displays, each of which implements a different operation, and a mobile communication terminal employing the method.

2. Description of the Related Art

Various types of mobile communication terminals have been developed in line with the advancement of technologies and consumers\' demands. Recently, mobile communication terminals can be divided into folder type terminals and slide type terminals. As the folder type terminals, dual LCD folder type mobile communication terminals which have LCD units provided on both sides of an upper folder are widely used.

FIG. 1 is a perspective view showing the exterior of the dual LCD folder type mobile communication terminal, and FIG. 2 is a perspective view showing the exterior of the dual LCD folder type mobile communication terminal when its folder is opened. The dual LCD folder type mobile communication terminal 100 includes a sub-LCD 110 provided at an outer side of an upper folder 101 and an internal main LCD 120 provided at an inner side of the upper folder 101.

As illustrated, the sub-LCD 110 has a relatively smaller screen in size than the main LCD 120. The sub-LCD 110 is provided to display basic information in an idle state, promoting users convenience. For example, it displays field strength, remaining battery capacity, time and date on one screen. In addition, an icon informing of an incoming call or corresponding simple message content when the dual LCD type mobile communication terminal receives a call can be displayed on the sub-LCD 110. In this state, when a user opens the upper folder 101 as shown in FIG. 2, a call can be connected, and in addition, when a message such as a text message is received by the mobile communication terminal, an icon informing of the message reception or corresponding short message content can be displayed on the sub-LCD 110. In this case, when the user opens the upper folder 101, the received message can be displayed on the main LCD 120. If the user does not immediately open the upper folder, the icon informing of the arrival of reception message is continuously displayed on the sub-LCD.

Meanwhile, a mobile communication terminal 200, which has a structure that a main LCD 210 is provided on an upper folder 210 and a touch panel 220 is provided on a lower folder 202 as shown in FIG. 3, has been presented. Generally, the touch panel 220 installed at a corresponding portion where a keypad is to be formed can display the keypad as shown in FIG. 4 as necessary. Namely, the touch panel 220 can output an image of the navigation keys 221 and number keys 222 and perform the same function as that of the general keypad upon receiving signals inputted therethrough. The mobile communication terminal with such a structure can solve a problem that may arise when the LCD is provided at an outer side and also resolve user inconvenience caused by a small image display region. When an installed file search function is executed by using the mobile communication terminal, a stored data list is displayed. A folder or a file of the displayed data can be executed or selected on the touch panel directly from a file explorer by using a stylus pen. In this respect, however, the function of the stylus pen is limited in its inputting to such as tapping, double tapping, dragging & dropping.

The dragging & dropping is used to copy or move a file. Namely, two file searches are executed on each display and a file desired to be copied is selected from one file explorer. A target folder is displayed on a display window of the other file searches and the selected file is dragged and dropped to the target folder.

However, the copying method can be possibly used only when the target folder and the filed to be copied are positioned together on the same screen, and in a state that the displays are separately divided, the dragging & dropping method cannot be used.

In an effort to solve the problem, an end portion recognition technique is favorably employed. Namely, in case where data is copied or moved from one display to another display, when a dragging reaches an end portion, the data is moved or copied to the other display. However, application of this technique requires a complicate algorithm. In addition, in case that a menu or an icon is positioned far from an end portion, the menu or the icon must be moved (dragged) up to the end portion for user inconvenience.

BRIEF DESCRIPTION OF THE INVENTION

One aspect of the present invention involves the recognition by the present inventors of the drawbacks in the related art, as explained above. Based upon such recognition, improvements in processing data between display regions can be achieved according to the present invention.

Certain features that may be part of the data processing method and system between display regions will not be described in much detail, merely to prevent the characteristics of the present invention from being obscured. However, such additional features may also be part of the data processing method and system of the present invention, as would be understood by those skilled in the art.

Therefore, one object of the present invention is to provide a mobile communication terminal capable of processing data copying and/or data moving between display regions, and a data display method using the same.

Another object of the present invention is to provide a mobile communication terminal capable of sufficiently utilizing two display regions, and a data display method using the same.

Yet another object of the present invention is to provide a mobile communication terminal capable of easily checking stored data through a simple manipulation, and a data display method using the same.

One exemplary feature of the present invention is to provide a mobile communication terminal in which data selected from a touch panel can be moved or copied to another display without employing an end portion recognition technique.

Another exemplary feature of the present invention is to provide a mobile communication terminal in which a control signal using a touch panel displaying a data list is analyzed and then moved to another display.

Hereinafter, the term ‘terminal’ is intended to refer to and cover various types of communication devices that support mobility (or may be fixed) and allows communication of information via wired and/ore wireless interfaces. Examples may include mobile stations, user equipment (UE), handsets or PDAs, etc.

To implement at least the above feature in whole or in parts, the present invention provides a mobile communication terminal comprising: a display unit having a plurality of displays, one of displays being formed as a touch panel; and a controller for analyzing a signal inputted through the touch panel to check whether movement conditions of data displayed on the touch panel are satisfied, and outputting a control signal for displaying the corresponding data on a different display region.

To achieve at least these advantages in whole or in parts, the present invention also provides a data display method of a mobile communication terminal having a display unit including a plurality of displays, one of the plurality of displays being formed as a touch panel, comprising: analyzing a signal inputted through the touch panel to check whether movement conditions of data are satisfied; and displaying the corresponding data on a different display region.

The data display method of a mobile communication terminal further comprises checking whether data selected through the touch panel can be movable.

In the data display method of a mobile communication terminal, data is moved based on a dragging direction using the touch panel.

In the data display method of a mobile communication terminal, the movement conditions are determined based on a movement speed of the pointing device in contact with the touch panel, the length of contact on the touch panel, and pressure applied to the touch panel for more than a certain time.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

DETAILED DESCRIPTION

OF THE INVENTION

FIG. 5 is a schematic block diagram showing the construction of the mobile communication terminal in accordance with the present invention.

The mobile communication terminal in accordance with the present invention includes: a display unit 90 for performing a general display function of a mobile communication terminal, a touch panel 80 formed with a certain distance from the display unit 90, a memory 20 storing various information, a touch panel controller 60 controlling driving of the touch panel 80; a display controller 70 for controlling driving of the display unit 90; a signal input unit 50 for converting a signal inputted through the touch panel 80 into an electrical signal and outputting it; a controller 30 for outputting a control signal corresponding to the input signal provided through the signal input unit 50; a timer 10 for providing a drive time information required for controlling of the controller 30; and a pressure sensor 40 for sensing pressure applied to the touch panel 80 and providing information on the sensed pressure to the controller 30.

The touch panel 80 displays a list of data stored in the memory 20 according to a control signal. The signal inputted through the touch panel 80 is transferred to the controller 30 via the signal input unit 50. The controller 30 analyzes the input signal. If movement conditions of data are met, the controller outputs a control signal for outputting corresponding data through the display unit 90.

In the construction of the present invention, one of the two display units is the touch panel, but in order to accomplish the objects of the present invention at least one or more display regions can be formed as the touch panel. Namely, two displays can be all the touch panels, and two or more display units can be formed in addition to the touch panel.

Also, various types of memory means, such as RAMs, ROMs, hard disk type memories, flash memories, a GRAM (Graphic Random Access Memory), an SGAM (Synchronous Graphic Random Access Memory), etc., can be also applied to store the moved or copied image for different types of image data (e.g., SMS (Short Message Service), an MMS (Multimedia Message Service), a graphic message, a DMB (Digital Multimedia Broadcasting), etc.

In the exemplary embodiment of the present invention, the touch panel 220 is formed on the lower folder 202 and the display 210 is provided at the upper folder 201, but the opposite case can be also applicable according to the concept of the present invention. As well as the terminal including the upper folder and the lower folder centering on a hinge, the present invention can be also applied to a terminal whose upper folder is slidably moved up and down so long as it has at least two or more display regions.

For the sake of explanation, liquid crystal display (LCD) devices and systems will be described, but the present invention is not intended to be limited to LCDs, as various concepts of the present invention are applicable to a wide variety of other display devices or equipments. Examples may include LCD screens, organic electro-luminescence (EL) display screens, light emitting diode (LED) screens, OLED (Organic LED) screen, plasma display screens, etc.

FIG. 6 is a flow chart illustrating the processes of a method for displaying data. Of the two separated display regions, data of the terminal is displayed on the touch panel 80. An output form of data can be a form of an icon, a menu, a folder or a file name (step S61).

A signal inputted through the touch panel is transferred to the controller 30 through the signal input unit 50. An icon can be selected by fingers or by using a stylus pen. The controller 30 analyzes the inputted signal (step S62), and checks whether a selected menu is a movable menu (or icon) (step S63).

If the selected menu is not a movable menu (or icon), the controller can output no message or an alert message informing a user that he/she has selected unmovable data. Here, the alert message may be provided in the form of an audible, visual, and/or tactile manner according to terminal\'s setup information.

If the user selected data is a movable menu or file, it is checked whether the signal inputted through the touch panel satisfies movement condition. In this case, there can be various types of movement conditions for allowing movement to be made without a procedure of recognizing an end portion. Also, there can be two types of operations of movement display. Namely, data on the touch panel 80 can be simply moved onto the display unit 90 and displayed in an enlarged or reproduced form, or data can be actually moved.
