The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger, a pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity depth and proximity position of the pointer, and perform various operation control according to the various input signals.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 156 and 157 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 156 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 157 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 156 and 157 may be configured as a touch screen capable of touch input.

For example, when a touch (contact touch or proximity-touch) is detected with respect to the first display unit or the TOLED 156, At least one of the image lists displayed in the TOLED 156 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 157 is controlled when touching the TOLED 156 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

In the overlapped state (the mobile terminal is in a closed state), the TOLED 156 is disposed in an overlapped manner on the lower side of the LCD 157. [ In this state, if a touch such as a long touch (for example, a touch that lasted for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 156 in advance, ) Causes at least one image of the image list displayed on the LCD 157 to be selected according to the sensed touch input. The result of the execution of the selected image is displayed on the TOLED 156.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 157 to the TOLED 156 (without performing an execution operation therefor). That is, when a user selects one area of the TOLED 156 corresponding to a specific entity of the LCD 157 In the case of a long touch, the control unit 180 moves the corresponding object to the TOLED 156 to be displayed. The entity displayed on the TOLED 155 may also be displayed on the LCD 157 in accordance with a predetermined touch input to the TOLED 156, for example, flicking, swirling, and the like. In this drawing, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 156.

If another input, for example a drag, is detected in addition to the long touch, the control unit 180 is a function related to the image selected by the long touch, for example, a preview screen for the image is displayed on the TOLED 156. [ As shown in FIG. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 displays a selection cursor (or a selection bar) of the LCD 157 in a state in which the preview screen is outputted while maintaining the long touch and further dragging the TOLED 156 toward another image And displays the image selected by the selection cursor on a preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch.

When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 156, the touch operation (long touch and drag) .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

FIGS. 6A and 6B are views referred to the description of the proximity touch recognition area where the proximity signal is detected and the haptic area where the tactile effect occurs.

6A shows objects such as icons and menu items in a circular form for convenience of explanation. The area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the center area as shown in FIG. 6A. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

In the case where the proximity touch recognition area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity touch area where the proximity signal is detected They can be set differently. That is, the haptic area may be set narrower than the proximity touch recognition area, or the haptic area may be set wider than the proximity touch recognition area. For example, in (a) of FIG. 6A, the area including the first area A and the second area B may be a proximity touch recognition area, and the first area A may be set as a haptic area.

(N > 4) as shown in Fig. 6 (a), as shown in Fig. 6 (b) It is also possible to divide into two areas. Each divided region can be configured to generate a tactile effect with different intensities or patterns. Even when the area in which one object is displayed is divided into three or more areas, the haptic area and the proximity touch recognition area can be set differently according to the use environment.

The size of the proximity touch recognition area may be changed depending on the proximity depth to the display unit 151. [ That is, as shown in (a) of FIG. 6, the corresponding proximity touch recognition area may be gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Or the contiguous touch recognition area corresponding to the proximity depth to the display unit 151 may be gradually increased. In this case as well, the haptic area can be set to a constant size regardless of the proximity depth to the display unit 151, such as the 'H' area shown in FIG. 6B (b).

 In the case of dividing the area in which the object is displayed for the setting of the haptic area or the proximity touch recognition area, in addition to the concentric segmentation as shown in Fig. 6A, segmentation in the horizontal direction or vertical direction, radial segmentation, And various methods such as partitioning can be used.

A configuration in which the above-described projector module is provided in the bar-shaped mobile terminal 100 will be described with reference to FIGS. 7A and 7B. 7A and 7B are perspective views of an example of a mobile terminal according to the present invention.

The main body 103 of the mobile terminal may be coupled with a projector body 105 having a projector module 155 so as to be rotatable.

That is, the projector body 105 can be hinged to the main body 103, and the projection angle can be adjusted when the image is projected using the projector module 155 provided in the projector body 105 And the camera 121 may be disposed on the projector body 105 so that the image projected by the projector module 155 can be photographed.

FIG. 7A shows a state before the projector body 105 rotatably coupled with the main body 103 is rotated, and FIG. 7B shows a state after the projector body 105 is rotated.

The mobile terminal 100 can display an image on the external screen using the projector module 155 when the projector function is activated according to the user's selection. At this time, the control unit 180 can control the projector function activation and the overall operation of the projector module 155. The control unit 180 sets the projector module 155 to an operable state as the projector function is activated and the projector module 155 is capable of displaying an image on the external screen under the control of the control unit 180 State is set. Here, the projector function can be realized by displaying the image stored in the memory 160 or received from the external terminal by the wireless communication unit 110 on the external screen by using the projector module 155 provided in the mobile terminal 100 And the like. The external screen includes all means for displaying an image projected by the projector module 155, and is not limited to the name or the format. For example, the projector function may be activated when a menu item of 'projector function execution' is selected through a menu search when a command function key for performing a projector function provided on a keypad or a touch screen is selected by the user. The image displayed on the external screen may match the image displayed on all or a specific area of the display unit 151 of the mobile terminal or may not be displayed on the display unit 151. [

The following embodiments can be implemented more easily when the display module 151 is configured as a touch screen. Hereinafter, the screen display displayed on the touch screen 151 will be referred to as a "first display", and the projection display projected by the projector module 155 will be referred to as a "second display".

In general, a pointer refers to means (for example, a stylus pen or a finger) for touching the touch screen, and may be a specific shape (for example, a stylus pen or a finger) displayed on a display For example, an arrow, an hourglass).

In this specification, the means for touching the touch screen is referred to as a " pointer ", and the display of a specific shape moved by an operation of a mouse, a touch pad, a touch screen, or the like will be referred to as a "cursor" The cursor may include an indication on the display indicating where the user can enter the text.

When a predetermined image is projected on the external screen through the projector module 155, a pointer for indicating a specific position on the screen may be used. In this case, the shadow of the pointer is inevitably generated on the screen by the light projected from the projector module 155. At this time, the image including the pointer and the shadow by the pointer can be recognized through the camera module 121 capable of photographing the same direction as the image projection direction of the projector module 155. The distance between the pointer and the shadow can be determined from the recognized image through the camera module 121. [ It is possible to recognize whether the displayed image is touched to a point indicated by the pointer according to the detected distance, and an operation corresponding to the recognized touched point can be performed. Thus, hereinafter, input through the user input unit 130 can be performed by the above-described method.

For convenience of explanation, it is assumed that the mobile terminal referred to below includes at least one of the components shown in FIG. In particular, the mobile terminal to which the present invention is applicable includes the wireless communication unit 110 and the projector module 155.

First Embodiment

A first embodiment according to the present invention provides a display method of projecting at least a part of a web page displayed on a web browser executed on a first display to a second display. This will be described with reference to FIGS. 8 and 9. FIG. 8 and 9 are state diagrams of a first display and a second display of a terminal related to the first embodiment according to the present invention.

8 (a), a web browser is executed on a touch screen 151 (first display) of a terminal 100 having a projector module 155, and a predetermined web page is displayed . At this time, the user can select the specific area 40 as the pointer 20 on the web page displayed on the first display. Here, the specific area 40 may be a multimedia object including a flash, a picture file, and a moving picture, or may be a part (area) of the selected web page by dragging the pointer 20, It could be the whole web page. Next, it is determined whether or not the selected object 40 is projected on the second display 10 through a predetermined menu operation as shown in FIG. 8 (b). If so, the selected object 40 may be projected onto the second display. 8 (c), the first display can freely move to another web page, and the object 40 displayed on the second display 10 can be moved to another web page if there is no other input from the user . ≪ / RTI > Accordingly, the user can freely browse another web page while leaving a portion of the previous web page to be continuously viewed on the second display 10.

In the above-described process, the specific area displayed on the second display 10 can be displayed through the following method.

First, there are actually two ways to use the web browser. One of them is executed in the first display. And the other is executed on the second display 10. That is, another web browser displays the selected area 40 of the web page in a cropped form on the second display 10. Therefore, if this method is used, if there is a moving object such as a flash, a GIF animation or a moving image in the selected specific area 40, the movement can be displayed as it is.

Secondly, the web browser executes only the first display, and captures the selected area 40 and displays it in the form of a still image. In this case, even if the above-described moving object is included in the selected region 40, it will be displayed only in the form of the captured moment.

Thus, both methods described above can be used in the manner in which the present invention is implemented, although the former is more preferred.

Next, the shape of the selected area 40 appearing on the second display will be described with reference to FIG.

The selected area 40 may be enlarged or reduced by a predetermined ratio on the second display 10, as shown in FIG. 9A or FIG. 9B. The enlargement / reduction ratio can be preset in the memory unit 160, and it is possible to change the magnification by a predetermined menu operation. It is also possible to display the selected portion 40 with the maximum resolution supported by the projector module 155. This may be more useful when the entire web page is selected as the portion to be displayed on the second display 10 as shown in Fig. 9 (c). Since the size and the maximum resolution of the touch screen 151 are limited by the size of the mobile terminal 100, it is difficult to view the entire web page at a time.

Second Embodiment

The second embodiment according to the present invention is characterized in that, in a web page displayed on a web browser executed on a first display, the application can be executed in a second display when an external driving program is required to execute or reproduce the selected contents And a mobile terminal. This will be described with reference to FIG. 10 is a state diagram of a first display and a second display of a terminal related to a second embodiment according to the present invention.

Referring to FIG. 10 (a), a web browser is executed on the touch screen 151 to display a web page providing a movie. At this time, the user can select the link (45) as the pointer (20) in order to view any movie content in the high image quality mode. In such a case, the content may be played back in the web browser itself, but a driving program other than the web browser (hereinafter referred to as "external application") may be required to reproduce the content. At this time, if the external application is executed on the second display 10 as shown in FIG. 10B, the web browser being used in the first display can be continuously used irrespective of execution of the external application. Therefore, as shown in FIG. 10C, the user can browse another web page with the web browser running on the first display, regardless of the movie content reproduced through the external application on the second display 10 Do. If it is desired to control the playback state of the movie content, the external application is loaded on the first display through a predetermined menu operation as shown in FIG. 10 (d). 10 (e), the external application is displayed on the first display, and the second display 10 can be controlled by the operation through the touch screen 151. [

Here, the high-definition moving picture content is described as an example in which an external application is required for reproduction. However, the present embodiment is not limited to this, and can be applied to any content or file for which an execution of an external application is required for reproduction or execution.
