Description

Video display device with object camera and detection sensor {A Display Device with A Object Camera and A Sensor}

The present invention relates to an image display device in which a physical keyboard is applied to a body such as a laptop or a virtual keyboard is applied to a screen display device such as a smart phone and a tablet. Object cameras and detection sensors applied to the body recognize the movement of objects such as a hand held, so that productivity tasks such as laptops or desktops can be performed without a mouse, and touch operations involving screen display devices are covered, scratched, and dirty. The present invention relates to an image display device including an object camera and a detection sensor that performs a navigation function by recognizing a motion of an object in a virtual space outside the area of a screen display device without doing so.

Since the application of the image input device to desktop computers began, a patent (Korean Patent 10-2002-0062714) that applied the image input device to the keyboard so that users can more accurately input the video chat screen was proposed, but it was not universalized.

Laptops, which are still widely used today, are being evaluated as a productivity tool that can be carried within a limited range due to the keyboard being applied on one side of the folding side. However, due to the limitation of shape invariance, carrying in a high state such as a one-handed grip It is not satisfactory, and even with a touch pad, it does not reach the productivity of the mouse.

As a mobile device with excellent portability, easy Internet search, and equipped with a shooting function, the user's environment has rapidly shifted from the desktop environment to the mobile environment after the advent of smartphones and tablets.

However, it is convenient to use image information in the conventional plate-shaped smartphone, but unlike a desktop or laptop computer, keyboard input and mouse input are limited, which makes it inconvenient to be used as a productivity tool.

Likewise, a tablet device having a plate shape also had a problem that it was difficult to input keyboard and mouse input, and a two-in-one product with a detachable cover applied with a keyboard function applied to one side covering the screen display surface of the tablet device was released. Although the same problem has been solved, the problems of inconvenient portability that cannot be gripped with one hand, the occurrence of scratch marks in contact with the keyboard on the screen display surface, and the use of a mouse input device, which is important as a productivity tool, are not solved.

In addition, a video display device to which a flexible display device capable of folding and winding is applied has a need to protect the screen display surface from scratches or imprints, along with a folding or winding part, which is a weak part of the flexible display device.

And the current size of flat-type smartphones is changing the trend from 16:9 products to 18:9 products with a screen size ratio, and even in the folded state of the shape variable image display device to which the flexible display device expected to be released in the future is applied. It is predicted that the 9 ratio will be maintained and applied, and when considering the application of a virtual keyboard to the top surface of the smartphone itself having such an 18:9 ratio, it will reach a size that can fully compose the keyboard without significant reduction.

In order to solve this problem, the patent filed by the inventor (Korean Patent Application No.: 10-2017-0096694) achieved the purpose of increasing portability and productivity, but due to the application of its own keyboard, the application space for batteries and camera modules were reduced. There is a problem that it is cumbersome to unfold and fold.

In addition, in the case of existing flat-type smartphones, a product in which a rotating camera that can shoot both the front and the back with a single camera is applied to one corner or a product in which the camera is accommodated and protruded at one corner has been released by some manufacturers.

The technical problem to be achieved by the present invention is as follows.

First, in an image display device supporting a physical keyboard or a virtual keyboard, it is intended to be able to perform productivity tasks such as a desktop to which a mouse is applied without carrying a separate mouse.

Second, it is difficult to apply a separate protective film, and in a foldable image display device with a transparent reinforced polyimide film that has less scratch resistance than tempered glass, the need to touch the polyimide film itself can be reduced, thereby reducing the possibility of scratching on the image display device. I want to be.

Third, it is intended to reduce the possibility of bacterial contamination by touch manipulation by reducing the necessity of direct touch manipulation using a finger, which has a high possibility of bacterial contamination.

In order to achieve the above technical task, a first embodiment of the present invention is an image display device having a control unit, a screen display device, and a body to which the screen display device is applied, and at one edge of the body, the screen display surface or the body of the screen display device When a physical keyboard is applied to the applied physical keyboard, a first inclined surface is formed that is not parallel to the applied surface of the applied physical keyboard, but is inclined, and the first inclined surface is located in front of the first inclined surface and moves the user's fingers, bare hands, or instruments.

When formed in the vertical axis of the first inclined surface and the vertical axis of the application surface of the display device forms an acute angle.

In the first embodiment, at one end of the first inclined surface, a second inclined surface is formed outside the wide-angle area to secure a wide-angle area of the object camera.

In the first embodiment, the control unit switches the object camera and object detection sensor applied to the body of the image display device to an inactive state when a separate keyboard to which the object camera and object detection sensor are applied is connected through wired or wireless method. It has a characteristic of performing control by activating an object camera and an object detection sensor applied to a separate keyboard.

Any one or more of the used distance sensor and the illuminance sensor that detects the change in illuminance is applied.

In the first embodiment, in the case of a video display field in which a first slope is applied to a horizontal edge and a vertical edge of the body and an object camera and an object detection sensor are applied to each of the first slope, When the keyboard is displayed, the object camera and object detection sensor applied to the first slope of the horizontal corner are not activated. When the virtual keyboard of the vertical mode is displayed on the display device, the object camera and the object camera applied to the first slope of the vertical corner are displayed. It has a feature that the object detection sensor is not activated.

The second embodiment, which is another embodiment of the present invention, is an image display device having a control unit, a screen display device, and a body to which the screen display device is applied, and is applied in a rotatable state at one edge of the screen display surface of the screen display device applied to the body. It is applied to the rotating body, the body, or any one side of the rotating body and is applied to the rotating shaft detection sensor or switch that detects the rotation of the rotating body, and the moving user's finger, bare hand, or a hand holding the device. It is configured to include an object camera for photographing an object.

In the second embodiment, an object detection sensor that detects an object entering or leaving the wide-angle area of the object camera and transmits the detected signal to the image display device is applied to one side of the rotating body to which the object camera is applied or the edge of the body outside the rotating body. do.

In the second embodiment, the object detection sensor is activated only when a rotation axis detection sensor or a switch detects that the rotation body has reached a set rotation angle.

In the second embodiment, the control unit switches the object camera and object detection sensor applied to the body of the image display device to an inactive state when a separate keyboard to which the object camera and object detection sensor are applied is connected through wired or wireless method. It has a characteristic of performing control by activating an object camera and an object detection sensor applied to a separate keyboard.

In the second embodiment, the object detection sensor is a thermal sensor that detects heat of an object entering or leaving the wide-angle area of the object camera, a static charge sensor that detects an electrostatic charge, a magnetic field sensor that detects a change in a magnetic field, and an ultrasonic reflection. Any one or more of the used distance sensor and the illuminance sensor that detects the change in illuminance is applied.

As described above, according to the embodiment of the present invention, the following advantages are obtained.

First, in the case of an image display device supporting a physical keyboard or a virtual keyboard, productivity tasks such as a desktop with a mouse can be performed without blocking the screen display device through motion recognition of the object using an object camera applied to the slope of the body. There will be.

Second, it is difficult to apply a separate protective film, and even in the case of a foldable image display device with a transparent reinforced polyimide film, which has less scratch resistance than tempered glass, the change of hand motion in the virtual object area is not performed without touching the polyimide film itself. By detecting and providing the same user experience as touch manipulation, it is possible to fundamentally reduce the possibility of scratching on the image display device to which the foldable body is applied.

Third, the possibility of bacterial contamination is reduced by providing the same user experience as the touch operation by detecting the change in motion of the object in the wide-angle area of the first slope outside the area of the display device without directly touching the screen display surface with a finger. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The terms used in the present specification are for describing exemplary embodiments and are not intended to limit the present invention. In this specification, the singular form also includes the plural form unless specifically stated in the phrase. In addition, reference numerals presented according to the order of description are not necessarily limited to the order, and some of the numerals assigned thereto may be omitted from the drawings.

1 is a conceptual diagram showing a user environment of a notebook, FIG. 2 is a conceptual diagram showing a touch operation environment of a smartphone and a cross-sectional view showing a wide angle of a front camera, and FIG. 3 is a horizontal mode wide-angle area overlap of a smartphone to which a virtual keyboard is applied. Fig. 4 is a conceptual diagram showing an example of using a horizontal mode of a tablet to which a virtual keyboard is applied.

As shown in Fig. 1, a working environment for document creation using a desktop or laptop requires a working board 1, a physical keyboard 5, a mouse pad 2, and a mouse 3.

Among these components, the mouse pad 2 and the mouse 3 are separate components from the desktop and notebook, and must be carried separately, and cannot be used in an empty space without a working board 1 such as a desk.

As shown in FIG. 2, navigation operations such as screen movement, reduction, enlargement, and double-click of the smartphone are mainly performed by the touch operation of the touch panel using the user's hand. Along with the disadvantage of covering the part, scratches occur while the finger continuously touches the outer surface of the screen display device 10 and contamination of both the smartphone and the finger occurs.

As a solution to this problem, a method of performing a navigation operation through recognition of a user's hand gesture using the front camera 7 applied to the smartphone itself may be considered, but this is difficult to apply due to the following problems.

First, when performing motion recognition of an object using the front camera 7, there is a problem that a hand part located at the upper part of the front camera 7 covers many parts of the screen display device 10.

Second, there is a problem that the front camera 7 must always be activated to perform object motion recognition, and a simple physical switch or virtual switch that performs activation and deactivation of the front camera 7 is applied to solve the problem. Even if it does, there is a new problem of hassle that the user must manually perform activation and deactivation each time.

Third, as shown in FIG. 3, the user's hand performing the keyboard input in the landscape mode use environment to which the virtual keyboard 6 of the smartphone is applied extends over the wide-angle area of the front camera 7. ), there is a problem that may cause an error in recognition of motion.

4 is a conceptual diagram showing an example of using a horizontal mode in which a virtual keyboard 6 is applied to a tablet, and when the self-applied front camera 7 is applied to detect the motion of an object such as a user's finger or hand, The interference problem does not occur in the same wide-angle area, but the problem that the user's hand covers a part of the display device 10 and the problem that the front camera 7 must be always activated are the same.

As one of the alternatives to solve the above problems, a patent (Korean Patent Application No.: 10-2017-0096694) has been filed by the inventor, but the application of a detachable keyboard reduces the battery application space of the body and makes it difficult to fold and unfold the camera module. There is a problem that it is cumbersome.

In addition, in the case of existing flat-type smartphones, a product that has a rotating camera that can shoot both the front and the rear with a single camera was applied to one corner of the flat-type smartphone body, but it is a product specialized for still image and video shooting, so that the user can manually shoot. In addition to the inconvenience of performing activation and deactivation directly, fingerprint marks remain on the camera lens by a finger, there is an inconvenience that the user must set a rotation angle for performing image recognition for navigation operation each time.

In addition, in the case of existing flat-type smartphones, some manufacturers have released products in which the camera is stored and protruded at one corner, but this is also a product specialized for still image and video shooting, and the user manually activates and deactivates the shooting mode. In addition to the inconvenience that must be performed, there is a problem in that it is impossible to change the rotation angle for performing image recognition for navigation operation.

In order to solve these problems, the present invention is the first embodiment in which the first inclined surface 110 is applied to the body 20 along with the illustrated drawings of FIGS. 5 to 32 and the rotating body 140 to the body 20. Examples are roughly presented as second embodiments to which are applied, and various detailed embodiments are presented according to the characteristics of the body 20 in each embodiment.

5 to 28, the first embodiment of the present invention is an image display device having a control unit, a screen display device 10, and a body 20 to which the screen display device 10 is applied. At one corner of the screen display device 10, when the physical keyboard 5 is applied to the body 20 or the screen display device 10, a first inclined surface ( 110) is formed, and an object camera 120 is applied to the first slope 110 to photograph an object such as a user's finger, a bare hand, or a hand holding an instrument, which is located in front of the first slope 110 and moves do.

In the first embodiment, the body 20 includes a notebook computer, a plate-shaped smartphone that is invariant in shape, a plate-shaped tablet that is invariant in shape, and an out-folding body that is variable in shape, an in-folding body, and a two-stage folding body capable of both in-and-out folding. do.

An object detection sensor 130 is applied to the body 20 of the first embodiment to detect an object entering or leaving the wide-angle area of the object camera 120 and transmit the detected signal to the image display device.

As shown in FIG. 9, the object detection sensor 130 detects that the user's hand outside the keyboard input area of the virtual keyboard 6 enters the wide-angle area of the object camera 120 and at the same time, the object camera 120 It is preferable to arrange it so that it can be activated and enter the photographing mode, and this arrangement has the advantage of minimizing the motion recognition waiting time.

To this end, in the first embodiment, the object detection sensor 130 is adjacent to the object camera 120 on the first slope 110 so that it is possible to enter the photographing mode simultaneously with the detection of the object detection sensor 130 as shown in FIG. 9. It is applied to the area.

In the first embodiment, when the physical keyboard 5 is applied to the body, the first inclined surface 110 has a first inclined surface 110 formed at one edge of the application surface of the physical keyboard 5, and the body 20 When the physical keyboard 5 is not applied, one or more first inclined surfaces 110 are formed at one or more of the horizontal or vertical corners forming the corner of the application surface of the display device 10.

The horizontal edge refers to a side with a relatively long length based on a case in which the display device 10 is in a maximum open state, and a vertical side refers to a side with a relatively small length.

As specifically shown in the cross-sectional views of FIGS. 7, 11, 12, and 15, in the first embodiment, when the first inclined surface 110 is formed at one edge of the application surface of the physical keyboard 5, the first inclined surface The vertical axis of 110 and the vertical axis of the application surface of the physical keyboard 5 form an acute angle, and when the first inclined surface 110 is formed at one edge of the application surface of the display device 10, the first inclined surface 110 The vertical axis and the vertical axis of the application surface of the display device 10 form an acute angle.

Since the first inclined surface 110 is formed at an acute angle at the corner of the body 20, the user's hand out of the keyboard input area even in a space without the working plate 1 and in various environments such as on the working plate 10. It is possible to smoothly detect the navigation operation without the mouse (3).

If the first inclined surface 110 is applied to the body 20 at a right angle rather than an acute angle, the problem does not occur in the state of the space without the working plate 1, but it is placed on the working plate 1 or on the knee. In the situation, due to the relationship in which the camera wide-angle axis 121 of the object camera 120 faces the working plate 1 or knee, the user's hand must move by touching the working plate 1 or knee. Together, there is a disadvantage in that it is impossible to utilize half of the wide-angle region located at the lower portion of the camera wide-angle axis 121 of the object camera 120.

As another case, when the first inclined surface 110 to the body 20 maintains an obtuse angle beyond a right angle, most of the wide-angle area is applied to the lower part of the camera wide-angle axis 121 of the object camera 120. There is a problem that the possible wide-angle area range is narrower than that in the case of a right angle.

As shown in FIGS. 8 to 12, the front camera 7 as shown in FIGS. 2 and 3 is not applied to the embodiment of the smartphone in which the object camera 120 is applied to the first slope 110 The camera 120 can also perform the function of the front camera 7 of the existing smartphone, and in this case, when the first slope 110 forms a right angle or an obtuse angle, it is impossible to take a selfie using the front camera 7 There are also disadvantages.

However, when the first inclined surface 110 has an acute angle, there is an advantage that a front photographing using the object camera 120 is possible, so that the front camera 7 can be replaced.

In addition, when the object camera 120 is applied in a rotatable state like the rotating body 140 of the second embodiment to be described later, there is a problem that fingerprints or contamination are generated on the lens by a finger when the user performs an operation to rotate the camera. Although a problem arises, in the case of applying the fixed first inclined surface 110 as in the first embodiment, since rotation is not required, this problem does not occur along with improvement in immediate response.

In the first embodiment, at one end of the first inclined surface 110, a second inclined surface 111 is formed outside the wide-angle area to secure a wide-angle area corresponding to the possible shooting range of the object camera 120.

In the first embodiment, the object detection sensor 130 is a thermal sensor that detects heat of an object entering or leaving the wide-angle area of the object camera 120, a static charge sensor that detects an electrostatic charge, and a magnetic field change. Any one or more of a magnetic field sensor, a distance sensor using ultrasonic reflection, and an illuminance sensor that detects a change in illuminance is applied.

20, 22, 24, 25, and 28, in the first embodiment, the first inclined surface 110 is applied to the horizontal and vertical corners of the body 20, respectively, and In the case of a video display in which the object camera 120 and the object detection sensor 130 are applied to the slope 110, when the virtual keyboard 6 in the horizontal mode is displayed on the display device 10, the horizontal edge The object camera 120 and the object detection sensor 130 applied to the first inclined surface 110 are not activated to avoid interference by the hand of the user performing text input or to avoid the long-term absence of input information and display the screen In a state in which the virtual keyboard 6 in the vertical mode is displayed on the device 10, the object camera 120 and the object detection sensor 130 applied to the first inclined surface 110 at the vertical edge are not activated.

As shown in FIGS. 10, 17, 19, and 21, the object camera 120 and the object detection sensor on the first inclined surface 110 even when the virtual keyboard 6 is not applied to the display device 10 In the case of the first embodiment to which (130) is applied, even if the user grips the body 20 with one hand and does not perform a touch operation to cover the screen with the other hand, the motion recognition in the wide-angle area outside the screen display surface is performed. It has the advantage of enabling navigation operation.

And, as shown in FIG. 19 of the first embodiment, in the case where the out-folding image display device is opened in a tent shape at an acute angle, the wide-angle area is activated for individual users located facing each other at the front and rear sides of the folding axis. It is also possible to obtain the convenience of providing a user environment that can be used.

In addition, as in the first embodiment, since the first inclined surface 110 is formed at an acute angle and inclined to the body 20, the smartphone or tablet is placed on the working plate 1 without support by the user's hand. Also, since the object camera 120 naturally faces the user's face, unlike the front camera 7 of FIG. 2, there is an additional advantage of enabling a natural video call.
