[0030] Hereinafter, an exemplary embodiment of the present invention having the above-described features will be described in more detail with reference to the accompanying drawings.

[0031] FIG. 1 illustrates an example of applying a multi-functional touch keyboard having a touch sensor according to an exemplary embodiment of the present invention to a general keyboard, FIG. 2 illustrates an example of applying the multi-functional touch keyboard having a touch sensor according to an exemplary embodiment of the present invention to a dual-monitor laptop computer keyboard, FIG. 3 is an enlarged diagram of a click key of the multi-functional touch keyboard having a touch sensor in FIGS. 1 and 2, FIG. 4 illustrates application of the multi-functional touch keyboard having a touch sensor in FIG. 2 to a dual-monitor laptop computer, and FIG. 5 illustrates a use example of the multi-functional touch keyboard having a touch sensor in FIG. 4. Here, FIG. 1A and FIG. 2B each illustrate a conventional keyboard configuration and a conventional keypad and touch pad configuration of a laptop computer.

[0032] Referring to FIGS. 1 to 5, there is a gist that the multi-functional touch keyboard having a touch sensor according to an exemplary embodiment of the present invention includes a key cap unit 110, a driving circuit unit (not illustrated), a support 120, a touch pad 130 constituted by touch sensors formed on upper ends of multiple key caps 111 grouped in a specific shape, a left click key 141 and a right click key 142 formed adjacent to both ends of the touch pad 130, and a control unit (not illustrated) moving a cursor in conjunction with a touch of the touch pad 130 and performing a click function by pressing the click keys, to perform a basic function as the keyboard and perform a touch pad function as a graphic controller.

[0033] First, the key cap unit 110 is constituted by a character key cap, a function key cap, a numeric key cap, a specific key cap, and a direction key cap which are arranged differently according to the type of an applied desktop computer, a laptop computer, or an ultrabook computer, and various keyboard specifications of 86 keys, 101 keys, 103 keys, or 106 keys.

[0034] Next, the driving circuit unit is constituted by a contact point and a membrane switch coupled to each of a lower end of the corresponding key cap 111 of the key cap unit 110, but may be configured variously according to a membrane scheme, a non-contact scheme, or a mechanical scheme, and the support 120 may support the membrane switch in response thereto.

[0035] Next, the touch pad 130 is constituted by multiple touch sensors formed on the upper ends of the multiple key caps 111 grouped in a specific shape, respectively as illustrated in FIG. 1B (blue) and FIG. 2B (red).

[0036] Here, the touch pad 130 may be formed by grouping up to the character key caps in a reverse triangular form based on a space key cap 143.

[0037] For example, the touch sensor is formed on each of upper ends of the space key cap 143, six key caps (from ‘C’ to ‘,’) 111 on a lower line of the character key caps, seven key caps (from ‘D’ to ‘L’) 111 on an intermediate line, and eight key caps (from ‘E’ to ‘P’) 111 on an upper line to constitute the reverse triangular form touch pad 130.

[0038] Meanwhile, a partition (not illustrated) having a predetermined height is formed on an upper periphery of the corresponding key cap 111 constituting an outline of the touch pad 130 to separate a touch area of the touch pad 130.

[0039] That is, when the touch area is recognized by a tactile according to the touch pad outline represented by FIG. 1B (blue) and FIG. 2B (red) to recognize the touch pad 130 without deviating a user's view from a screen under the work.

[0040] Alternatively, the corresponding key cap 111 constituting the outline of the touch pad 13 and another adjacent key cap 111 are formed spaced apart from each other at a predetermined distance (not illustrated) to separate the touch area of the touch pad 130.

[0041] That is, the touch area is recognized by the tactile by setting a free space between the key cap 111 of the touch pad 130 and another adjacent key cap 111 to recognize the touch pad 130 without deviating the user's view from the screen under the work.

[0042] Next, the left click key 141 and the right click key 142 performing a left click function and a right click function of a general touch pad or mouse are formed adjacent to both ends of the touch pad 130.

[0043] That is, as enlarged and illustrated in FIG. 3, the left click key 141 and the right click key 142 are separately formed on both ends of the space key cap 143, respectively to perform the left click function and the right click function by pressing the left click key 141 and the right click key 142.

[0044] Here, the left click key 141 and the right click key 142 divide both end portions of the space key cap 143 to which a sufficient area is provided into sizes of the character key caps, respectively to provide a left click button and a right click button.

[0045] Meanwhile, when a horizontal scroll is performed by horizontally touching a touch pad area of an upper surface of the space key cap 143 in conjunction with double strokes of the right click key 142, and a vertical scroll is performed by vertically touching a touch pad area except for the space key cap 143, and a left click and double clicks may be performed by a stroke and double strokes of the left click key 141, respectively and a right click may be performed by the stroke of the right click key 142.

[0046] Next, the control unit moves a cursor on a display in conjunction with the touch of the touch pad 130, and a click function on the display is performed by pressing the left click key 141 and the right click key 142.

[0047] Therefore, as illustrated in FIG. 5A, the cursor may be moved in conjunction with the touch of the touch pad 130, and as illustrated in FIG. 5B, the click function may be performed by pressing the left click key 141 and the right click key 142.

[0048] Meanwhile, as illustrated in FIGS. 2, 4, and 6, the key cap unit 110 and the touch pad 130 are configured to be disposed at the location of the touch pad or the lower palm rest of a general laptop computer and a separate sub monitor 220 other than a main monitor 210 is formed in a free space on an upper end of the laptop computer to hinge-rotate based on a hinge axis 221 to enable an efficient screen operation on the monitor.

[0049] That is, if an additional sub monitor is provided while maintaining an structure and form of the laptop computer in the related art, a device becomes thicker and a weight of the device increases due to installation of an additional monitor, and as a result, this goes against the trend of light weight and slimming as a portable integral device. Therefore, even though the additional monitor is provided, it is premised that the existing slimming is maintained, and the weight does not increase by basically maintaining an integral type.

[0050] Therefore, referring to FIG. 4, while equally maintaining a horizontal width, a second size of the sub monitor 220 is formed as 35 to 45% of a first size of the main monitor 210, and preferably, 40%, and the light weight may be implemented by minimizing the weight due to the sub monitor 220 while ensuring readability and availability of the sub monitor 220.

[0051] For example, as illustrated in FIG. 6, the main monitor 210 and the sub monitor 220 divide the screen to provide each of different UIs to be operated as a monitor for an additional task or an auxiliary task in an inclined form at a predetermined angle by raising the upper end of the sub monitor 220 with the hinge axis 221 as a rotational axis upon use depending on user's efficiency and convenience.

[0052] By the way, the touch pad is replaced and removed by applying the touch keyboard to the laptop computer, and as a result, the touch pad is not required and a space at which the palm rest on the lower end of the keyboard occupied by the touch pad is positioned may be utilized, and unlike the existing laptop computer, the touch keyboard may be positioned in the lower space at which the ensured palm rest is positioned and the sub monitor may be disposed on the upper end where the keyboard used to be positioned, and a space capable of being provided with the sub monitor is provided by applying the touch keyboard to the integral device such as the laptop computer and providing an additional space for providing the sub monitor is excluded and a cause for an increase in existing thickness and weight of the laptop computer is not provided to satisfy a premise of providing the sub monitor.

[0053] Meanwhile, FIG. 6 illustrates utilization of the dual-monitor laptop computer to which the multi-functional touch keyboard having a touch sensor in FIG. 4 is applied, FIGS. 7A to 7C and 8A and 8B each illustrate monitor division use by a user's UI manipulation in the dual-monitor laptop computer in FIG. 6, and FIGS. 9A and 9B, 10A, 10B, 11, and 12 each illustrate monitor division use by a UI provided by a program provider in the dual-monitor laptop computer in FIG. 6 in comparison with the existing screen.

[0054] The main screen and the sub screen are divided by a UI manipulation according to a taste of the user and efficiency to display the divided main screen and sub screen on the main monitor 210 and the sub monitor 220, respectively.

[0055] That is, in the case of a screen provided so that a predetermined form is changed and rearranged as the user desires, the screen may be divided and operated according to the taste of the user and the efficiency.

[0056] As illustrated in FIGS. 6, 7A, 7B, 7C, 8A, and 8B, a screen operation example in which the user disposes the main screen in the main monitor 210 according to the convenience and separates and appropriately disposes the sub screen in the sub monitor 220 to efficiently operate the screen is described in detail as follows.

[0057] FIG. 7A illustrates an example in which a document edition window W1 and a pop-up advertisement window P are displayed, FIG. 7B illustrates an example in which a web surfing window W2 and a YouTube video window U are displayed, and FIG. 7C illustrates an example in which the web surfing window W2 and a messenger window M are displayed. As illustrated, in the conventional case, the document edition window W and the pop-up advertisement window P are overlapped and displayed (an existing screen of FIG. 7A), the web surfing window W and the YouTube video window U divide the screen (an existing screen of FIG. 7B), or the web surfing window W and the messenger window M are overlapped and displayed. According to an exemplary embodiment of the present invention, the main screen of document edition W1 or web surfing W2 under the work may be displayed in the main monitor 210, and, in the sub monitor 220, a pop-up advertisement (side box advertisement P) (a screen of the present invention in FIG. 7A) or a program update notification may be displayed. YouTube may be reproduced and displayed (a screen of the present invention in FIG. 7B), or a messenger or SNS may be displayed (a screen of the present invention in FIG. 7C).

[0058] Therefore, since a projection screen P of the pop-up advertisement and the program update notification which suddenly appears without notice under the work covers the main screen being worked and is displayed as a top screen, the projection screen P continuously becomes a subject of inconvenience and complaint to a user who wants to concentrate on the work. Therefore, a window taskbar is moved to and displayed in the sub screen and all advertisements and projection screens are displayed in the sub screen 220 to resolve the inconvenience and complaint.

[0059] Further, when the document edition or the web surfing is performed while watching YouTube, there is inconvenience that the screen is divided, and the size of the window is adjusted to be small so that both windows are viewed in order to enable multi-tasks. When the document edition or web surfing screen is displayed on the main screen and the YouTube is reproduced on the sub screen in order to overcome such inefficiency and inconvenience, the multi-tasks may be enabled easily.

[0060] Further, when a program which interlocks with a smartphone, such as the messenger (Kakaotalk, Line, Facebook messenger) or SNS (Twitter, Facebook, Instagram) is used while performing a main task such as the document edition or web surfing, the screen is overlapped and displayed, and as a result, message confirmation and transmission are inconvenient. Therefore, when the document edition or web surfing screen is displayed on the main screen and the messenger or SNS screen is disposed and used on the sub screen, the message confirmation is possible without screen switching to enable simultaneous tasks.

[0061] Further, referring to FIGS. 8A and 8B, a document preparation tool, a development tool, or an image edition tool may be displayed, a ribbon menu of the corresponding tool may be disposed and displayed in the sub monitor 220 (FIG. 8A), a video conference multi-video V may be displayed in the main monitor 210, and a sub screen W3 which is under an auxiliary task may be displayed in the sub monitor 220 (FIG. 8B).

[0062] Therefore, as a requirement of the user is complicated, functions of the document preparation tool, the development tool, and the image edition tool are diversified and the tools are multi-functioned in order to accommodate the complicated requirement, and there are more and more icons to be displayed in the ribbon menu and thus, an area displaying the menu is gradually widened and a utilizable main screen of the main monitor 210 is gradually reduced. To improve this, when the ribbon menu of each tool and the main task window are separated, and only the main task window is disposed on the main screen and the ribbon menu is disposed on the sub screen, spatial utilization is maximized to provide a main task window having a maximum size.

[0063] Further, when auxiliary materials required for a meeting is searched or the meeting is performed while viewing materials to be referred, during a video conference in a full screen mode with multiple counterparts, if material searching and reference materials are executed on the sub screen, an efficient video conference may be enabled.

[0064] Alternatively, as illustrated in FIGS. 9 to 12, a UI modified, changed, and provided by the program provider may be divided into the main screen and the sub screen, and displayed in the main monitor 210 and the sub monitor 22, respectively.

[0065] That is, as a case where the user may not arbitrarily modify, change, and dispose the UI, a screen operation example in which a company providing a program modifies, changes, and provides the UI of the screen according to the dual monitors at first in order to efficiently use a screen space of the dual monitors to efficiently use the space is described as follows.

[0066] Referring to FIGS. 9A and 9B, the main screen under the work may be displayed in the main monitor 210, and, in the sub monitor, a program list which is running may be displayed (FIG. 9A), or a recently used file or a recently used program may be displayed (FIG. 9B).

[0067] Therefore, as illustrated in FIG. 9A, the sub monitor 220 is used as a taskbar/[currently running program list] display area, and when an alt-tab or win-tab key is input, [currently running program list] may be displayed and the program may be selected in the list and switched and displayed to the main window, but there is a disadvantage in that [currently running program list] is displayed on the main window under the work, and as a result, when [currently running program list] is continuously displayed by utilizing the sub screen, switching to a required program may be enabled by one motion.

[0068] Further, as illustrated in FIG. 9B, when the win-tab key is input, [program list which run up to now] may be displayed on a lower end of [currently running program list], when the program is selected in the list, the corresponding program may be executed and displayed in the main window, and there is a disadvantage in that [program list which run up to now] is displayed on the main window under the work and the list may be viewed after two operations of pressing the win-tab key and moving the win-tab key downward, and as a result, when [program list which run up to now] is continuously displayed by utilizing the sub screen, switching to a required program may be easily enabled.

[0069] Further, referring to FIGS. 10 to 12, a YouTube video may be displayed in the main monitor 210 in a YouTube full screen mode and a YouTube video list may be displayed in the sub monitor 220 (FIG. 10A), a streamer video may be displayed in the main monitor 210 and a chatting screen may be displayed in the sub monitor 220 (FIG. 10B), a slide show screen of a presentation program may be displayed in the main monitor 210 and a slide overview screen or an edition screen of the presentation program may be disposed and displayed in the sub monitor 220 (FIG. 11), or a search result list page of a web shopping homepage may be displayed in the main monitor 210 and a product detail information page for a product selected in a search result list may be displayed in the sub monitor 220 (FIG. 12).

[0070] Therefore, in order to view another video while watching the YouTube in the full screen mode, another video may be selected only when the full screen mode is terminated, but when the YouTube may be reproduced on the main screen in the full screen mode, and a video to be reproduced next is selected while viewing a list to be reproduced on the sub screen, a next video may be watched by one motion, so it may be convenient.

[0071] Further, in a network game and a YouTube broadcast, when users having a common goal are gathered and are chatting in order to communicate with each other while playing a game or viewing a broadcast, chatting contents are primarily displayed at one side of the screen and displayed in a part of a game screen or a part of a broadcast screen, and in the case of the YouTube, when the broadcast screen is displayed in the full screen mode, the chatting contents may not be viewed. Therefore, even though the game screen or the broadcast screen is displayed on the main screen in the full screen mode by separating the chatting screen from a network game screen or a YouTube broadcast screen, the chatting contents may be viewed on the sub screen to facilitate game execution and YouTube broadcast watching.

[0072] Further, when a slide is edited in Powerpoint, and then the screen is moved to the slide show screen, the slide is displayed in the full screen mode, and as a result, it is inconvenient that the slide screen displayed in the full screen mode should be terminated in order to edit the slide or select another slide. Therefore, when the slide overview screen or the edition screen is disposed and displayed on the sub screen while the slide show screen is continuously displayed on the main screen, the edition and the selection of another slide may be conveniently performed while confirming the slide show screen.

[0073] Further, in a general web shopping homepage, when the product is selected in the search result list page after searching the product, the current screen is moved to a detailed information page screen, and as a result, it is cumbersome that shopping should be performed while the search result list page and the product detail information page are moved forward and backward. Therefore, when the product detail information page is displayed on the main screen and the search result list page is displayed on the sub screen to display the product detail information page selected in the product search result list on the main screen, the product detail information page may be viewed by one selection, and as a result, convenience of the shopping may be doubled.

[0074] Accordingly, by a configuration of the multi-functional touch keyboard having a touch sensor described above, a touch sensor of a touch pad is attached to a keyboard surface to perform a function, but is not attached to an entire surface of a keyboard, but provides an area at least as large as an existing touch pad by considering operational efficiency and convenience, and economics of production, and the touch pad is attached up to a surface part of a character keyboard in a reverse triangular from starting from a space bar of a basic type keyboard to replace the existing mouse and a touch pad of a laptop computer performing a function as a graphic controller, and as a result, inconvenience of operating a computer with a separate graphic controller is excluded and in particular, in the case of the laptop computer, the touch pad is replaced and removed, thereby providing an efficient function by utilizing spaces occupied by a keyboard touch pad occupied by the touch pad and a lower palm rest.

[0075] Further, each of a left click key and a right click key is configured by dividing the space bar to perform a left-right click function of the mouse or the touch pad.

[0076] Furthermore, there may be an effect of the invention that the touch keyboard itself performs the function as the graphic controller and inconvenience that the mouse or the touch pad as the graphic controller is separately provided is excluded, and in particular, there is a significant meaning in that an opportunity to solve a premise of providing a sub monitor is provided by applying the touch keyboard to an integral device such as the laptop computer, resulting in becoming a start point of enjoying a benefit of providing dual monitors.

[0077] Configurations illustrated in the exemplary embodiments and drawings disclosed in the present specification are only the most preferred embodiment of the present invention and do not represent all of the technical spirits of the present invention, and thus it is to be understood that various equivalents and modified examples, which may be substituted for them at the time of filing the present application.
