Description

TOUCH-SCREEN DEVICE, AND CONTROL METHOD FOR

THE SAME

Technical Field

[1] The present invention relates to a touch-screen device and a control method for the same, in which when the touch-screen device is connected to an external monitor in a line-out mode, the touch-screen device is set in a touch-pad mode so as to be used like a mouse pad. Background Art

[2] A touch-screen is referred to as a screen having a special input device through which the position value for a touch by hand is input. When a user touches a character shown on the touch-screen or a specific position of the screen by using the user's hand or an object without using a keyboard, the touch-screen detects the touched position so as to perform predetermined processing by using software stored therein.

[3] In such a touch-screen, a touch panel having a plurality of rectangular lattices installed therein is attached on the screen of a general monitor. When a user touches the touch panel, the touched position is detected. The touch panel may grasp the touched position through infrared rays. Recently, the following method has been used. That is, two sheets of films are mounted on the surface of a liquid crystal display (LCD) so as to be spaced from each other. Further, when a user touches a specific portion, the films are contacted with each other at the portion. Then, X-axis resistance and Y-axis resistance are converted into digital values by an analog-digital converter, and the coordinates of the portion are extracted in accordance with the resolution of the LCD.

[4] Therefore, when a user touches a character or picture information displayed on the screen having the touch panel by using the user's hand, it is detected what item the user has selected, depending on the touched position of the screen. Then, a computer processes a corresponding command such that the user can easily obtain the information he/she wants.

[5] Because of such a characteristic of the touch-screen, the touch-screen is frequently used in guide software installed in subway stations, department stores, banks and so on. Further, the touch-screen is applied to business terminals as well as selling terminals used in various stores.

[6] Specifically, such a touch-screen is used in a portable multimedia player (PMP), a personal digital assistant (PDA), a personal video recorder, a digital video recorder and so on. [7] In the PMP or PDA having a conventional LCD touch-screen mounted thereon, the

LCD touch-screen is used as an input device as well as a display device. In such a touch-screen, it is important to analyze a user command from coordinates touched by a user. That is, it is important to analyze which menu or icon a user clicks.

[8] When products using the conventional LCD touch-screen as an input device and having a line-out function operate in a line-out mode, the touch-screen cannot be used because the resolution of the touch-screen is not fitted to that of an external monitor. In the line-out mode, a display screen output from the product using the touch-screen as an input device is connected to an external monitor through a line-out terminal.

[9] In this case, existing products receive an input through a keyboard, a push button, or jog key in the.

[10] In PMPs, PDAs, video recorders using such a touch-screen, the resolution of a display screen is adjusted by a formatter or a video encoder just before the final output. Only one formatter or video encoder is mounted in each device because of cost.

[11] Such a video encoder is configured as one chip including other function modules.

This chip includes only one video encoder module, which means that two or more video encoders are not used.

[12] Therefore, when an LCD touch-screen built in PMPs and so on is used as a display device, the video encoder configures a display screen in accordance with the resolution (for example, 320x240) of the LCD touch-screen.

[13] On the other hand, when an external monitor is used as a display device, the external monitor requires higher resolution than the built-in LCD touch-screen, because the external monitor has a larger screen than the LCD touch-screen. Therefore, the video encoder configures a display screen with higher resolution (for example, 720x480) than that of the LCD touch-screen.

[14] Since only one video encoder is provided, the display screen can be formatted with only one kind of resolution. Therefore, during the line-out mode (that is, 720x480), display is not output on the LCD touch-screen built in the PMP. If a screen formatted with resolution of 720x240 is displayed on the LCD touch-screen with resolution of 320x240, only a portion of the entire screen is displayed. Therefore, the display of the LCD touch-screen is turned off.

[15] Since nothing is output on the LCD touch-screen, the LCD touch-screen is not used.

That is, when the LCD touch- screen on which nothing is displayed is clicked or double-clicked, the LCD touch-screen may malfunction. Therefore, the display of the LCD touch-screen is turned off.

[16] As such, during the line-out mode, a large external monitor is used as a display device. Therefore, a screen is not output on the built-in LCD touch-screen.

[17] In such a conventional LCD touch-screen, however, the following problems occur during the line-out mode.

[18] First, the resolution of the LCD touch-screen does not correspond to that of the

CRT monitor. For example, while the resolution of the LCD touch-screen is 320x240 or 640x480, the resolution of the CRT (cathode ray tube) monitor is 720x480 or 720x576. Therefore, when the display of the LCD touch-screen is not turned off, only a portion of the screen is displayed on the external CRT monitor connected through a line-out terminal.

[19] Second, the screen ratio of the LCD touch-screen does not coincide with that of the

CRT monitor. Therefore, when the display of the LCD touch-screen is not turned off, a normal screen is not displayed on the external CRT monitor.

[20] Accordingly, when the touch-screen is used in the line-out mode, the display of the

LCD touch-screen is turned off.

[21] When the display of the LCD touch- screen is turned off, an input through the touchscreen is disabled. Therefore, since the touch-screen cannot be used in the line-out mode, an input depends on a keyboard, a push button, or a jog key, which may give users inconvenience.

[40] The external monitor 50 may be composed of at least one of a CRT, an LCD, and a wide TV.

[41] FIG. 3 is a flow chart showing a control method for the touch-screen device according to an embodiment of the invention.

[42] As shown in FIG. 3, the control method includes the steps of: driving an apparatus having the LCD touch-screen 10 mounted thereon (step STl); judging whether or not the line-out mode is set in the apparatus having the LCD touch-screen 10 mounted thereon (step ST2); when the line-out mode is not set, performing the touch-screen mode such that display is performed on the LCD touch-screen 10 (step ST3); and when the line-out mode is set, performing the touch-pad mode such that the LCD touchscreen 10 functions as a mouse pad (step ST4).

[43] FIG. 4 is a detailed flow chart showing the process of performing the touch-pad mode in FIG. 3.

[44] In step ST4, one or more of a mouse click event, a mouse point movement event, a mouse drag event, a double click event, and a drag-and-drop event are performed in accordance with a change in coordinates caused by pressing the LCD touch-screen 10.

[45] Step ST4 includes the steps of: judging whether the LCD touch-screen 10 is pressed or not (step STl 1); when it is judged that the LCD touch-screen 10 is pressed, judging whether a change in coordinates occurs in the pressing or not (step ST 12); when it is judged that a change in coordinates occurs, performing a mouse click event and returning the process to step STl 1 (step ST 13); when it is judged that a change in coordinates occurs, judging whether a change in coordinates continuously occurs (step ST 14); when it is not judged that a change in coordinates continuously occurs, performing a mouse point movement event and returning the process to step STl 1; and when it is judged that a change in coordinates continuously occurs, performing a mouse drag event and returning the process to step STl 1 (step ST 16).

[46] In step STl, the apparatus having the LCD touch-screen 10 mounted thereon is one of PMP, PDA, a personal video recorder, a digital video recorder, and a mobile TV.

[47] Now, the touch-screen device and the control method for the same according to the invention will be described in more detail with reference to the accompanying drawings.

[48] When it is judged that the specific description of related known function or constitution can cloud the point of the invention, the description will be omitted. Terms to be described below are defined in consideration of the functions of the invention. Accordingly, the meaning of the terms should be interpreted on the basis of the content of the specification.

[49] A technical feature of the present invention is that when a touch-screen is used in the line-out mode where it is connected to an external monitor, the touch- screen can be set in the touch-pad mode so as to be used like a mouse pad. Therefore, it is possible to provide users with convenience.

[50] The LCD touch-screen 10 serves to deliver a signal to the MICOM 30 when an icon or button shown on the screen is clicked. However, when the LCD touch- screen 10 is turned off in the line-out mode, a screen is not shown on the LCD touch-screen 10. Then, an input cannot be performed.

[51] In this case, conventional products receive an input through a key pad, which may give users inconvenience.

[52] In the present invention, although a display screen is not shown on the LCD touchscreen 10, the LCD touch-screen can perform a touch-pad function such that an input can be made on the LCD touch-screen 10.

[53] Therefore, when a user touches the LCD touch-screen 10, which operates in the touch-pad mode, during the line-out mode where the display screen is not shown, a change in the touched position of the LCD touch-screen 10 is detected. Then, a user is allowed to perform an input operation through the touch- screen which is emulated like a mouse pad used in notebooks.

[54] The emulation in a software context is the use of an application program or device to imitate the behavior of another program or device. For example, since an Apple computer has a basic system which is totally different from Microsoft Windows, software by Microsoft cannot be used on the Apple computer. However, if emulator software is installed on the Apple computer, the software by Microsoft can be used on the Apple computer.

[55] In the present invention, such a method is adopted. That is, the emulation function is used in such a manner that although the LCD touch-screen 10 is not a touch pad, the LCD touch-screen 10 operates like a touch pad in a specific situation (that is, the line- out mode). [56] Currently, most products such as PMP, PDA, a personal video recorder, a digital video recorder, and a mobile TV provide users with convenience through a graphic user interface (GUI). [57] When the present invention is applied to such products, an input can be made through touch, even though the display of the LCD touch-screen 10 is turned off.

Therefore, it is possible to provide users with convenience in any situation. [58] In particular, the effect will be maximized in products such as Windows and Linux in which the GUI is mainly used.

[59] Now, the operation of the invention will be described in more detail.

[60] FIG. 1 is a block diagram showing an example where a touch-screen device according to an embodiment of the invention connected is connected to a monitor. [61] The position value of a touched portion on the LCD touch-screen 10 is input, and display is performed on the LCD touch-screen 10. When the line-out mode is not set, the LCD touch-screen 10 operates in the touch-screen mode. Further, when the line-out mode is set, the LCD touch-screen 10 operates in the touch-pad mode. The resolution of the LCD touch-screen 10 may be set to 320x240 or 640x480. [62] The key pad 20 may be a keyboard, a push button, or a jog key, through which a key value is input. [63] The MICOM 30 processes the position value of a touched portion on the LCD touch-screen 10 and a key value input from the key pad 20. [64] When the line-out mode is not set, the MICOM 30 controls the video encoder 40 to set a display format with the resolution of the LCD touch-screen 10 such that a display screen encoded by the video encoder 40 can be output on the LCD touch-screen 10. [65] When the line-out mode is set, the MICOM 30 controls the LCD touch-screen 10 to perform the touch-pad mode. Further, the MICOM 30 controls the video encoder 40 to display image data on the external monitor 50 in accordance with resolution which is fitted to the external monitor 50. [66] The video encoder 40 is controlled by the MICOM 30. During the line-out mode, the video encoder 40 is connected to the external monitor 50 so as to configure and output a display screen in accordance with the resolution of the external monitor 50.

When the line-out mode is not set, the video encoder 40 configures a display screen in accordance with the resolution of the LCD touch-screen 10 so as to display image data on the LCD touch-screen 10. [67] The external monitor 50 may be CRT, LCD, or wide TV. The resolution of the monitor 50 is 720x480 or 720x576, which is higher than that of the LCD touch-screen. [68] FIG. 2 is a block diagram showing an example where a touch-screen device according to another embodiment of the invention is connected to a monitor. When such an example is applied to a mobile TV, it can be more effectively used.

[69] The LCD touch-screen 10, the key pad 20, the MICOM 30, and the video encoder

40 are constructed in a similar manner to those of FIG. 1. Further, their functions are also similar.

[70] The HDD or flash memory 31 is a non- volatile memory which stores data necessary for the MICOM 30.

[71] The audio codec 41 is controlled by the MICOM 30 and outputs a voice signal to a voice output device connected to the external monitor 50 during the line-out mode.

[72] FIG. 3 is a flow chart showing a control method for the touch-screen device according to an embodiment of the invention.

[73] First, an apparatus having the LCD touch-screen 10 mounted thereon is driven (step

STl). The apparatus having the LCD touch-screen 10 mounted thereon is one of PMP, PDA, a personal video recorder, a digital video recorder, and a mobile TV.

[74] Then, it is judged whether or not the line-out mode is set in the apparatus having the

LCD touch-screen 10 mounted thereon (step ST2).

[75] When it is not judged that the line-out mode is set, the touch-screen mode is performed, in which display is performed on the LCD touch-screen 10. That is, the MICOM 30 controls the video encoder 40 to encode a display screen in accordance with the resolution of the LCD touch-screen 10. Then, the MICOM 30 outputs the display screen encoded by the video encoder 40 onto the LCD touch-screen 10 (step ST3).

[76] When it is judged that the line-out mode is set, the touch-pad mode is performed, in which the LCD touch-screen 10 functions as a mouse pad. That is, the MICOM 30 controls the video encoder 40 to encode a display screen in accordance with the resolution of the external monitor 50. Then, the MICOM 30 outputs the display screen encoded by the video encoder 40 onto the external monitor 50, and the LCD touchscreen 10 operates in the touch-pad mode, like a mouse pad (step ST4).

[77] FIG. 4 is a detailed flow chart showing the process of performing the touch-pad mode of FIG. 3.

[78] One or more of a mouse click event, a mouse point movement event, a mouse drag event, a double click event, and a drag-and-drop event are performed depending a change in coordinates caused by pressing the LCD touch-screen 10.

[79] The mouse click event is to place a mouse point on a specific position on a display screen and click a mouse button to perform a corresponding function. The mouse point movement event is to move a mouse point shown on a display screen. The mouse drag event is to move a mouse while pressing a button and is also referred to as the click and drag event.

[80] In addition, a double click event and a drag-and-drop event may be performed. The double click event is to quickly click a button twice. The drag-and-drop event is to position a pointer in an object, move a mouse while pressing a mouse button, and then release the mouse button. In normal programs, clicking a mouse button once means selection, and clicking a mouse button twice means execution.

[81] In the process of performing the touch-pad mode, it is first judged whether the LCD touch-screen 10 is pressed or not. In this case, the pressing may be performed once or twice or may be continuously maintained, depending on the mouse click event, the mouse point movement event, the mouse drag event, the double click event, and the drag-and-drop event (step STI l).

[82] When it is judged that the LCD touch-screen 10 is pressed, it is judged whether the coordinates of the position value are changed in the first and second presses or other following presses (steps ST12, ST14).

[83] When it is judged that the coordinates of the pressed position are changed, the mouse click event is performed (step ST13).

[84] When it is not judged that the coordinates are changed between the first and the second pressed poistions, the mouse point movement event is performed (step ST 15).

[85] When it is judged that the coordinates are continuously changed with respect to the pressed position, the mouse drag event is performed (step ST 16).

[86] As described above, when the touch-screen is connected to an external monitor in the line-out mode, the touch-screen can be set in the touch-pad mode so as to be used like a mouse pad. Therefore, it is possible to provide users with convenience.

[87] While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications in form and detail may be made therein without departing from the scope of the present invention as defined by the following claims.
