As a video display device that can replace a plate-type fixed smartphone, various foldable video display devices with flexible displays have been proposed, and these foldable video display devices are hinged and hinged depending on whether or not hinges are applied at the folding part. Separated in a number of ways (Korea Patent 10-0125125, 10-0017875, 10-0106358, 10-0129704, 10-0017606) has been proposed.

Among the patents presented above, except for the Republic of Korea Patent 10-0106358 proposed by the present inventors, only the folding method is different, the image display device on the plate is folded to the plate for easy portability, and it is unfolded again on the plate, and only the simple physical function of providing a large screen is presented identically. Is becoming.

The Republic of Korea Patent No. 10-0106358 previously presented by the present inventor includes an example that enables a triangular prism folding state, but a cover plate corresponding to the first body and the third body of the embodiment of the present invention (hereinafter presented by the inventor) The first body and the third body to be hinged have a hinge diameter smaller than or equal to the thickness of the first body and the third body, while the hinge diameter of the cover plate of the existing patent is several times larger than the thickness of the thin plate-shaped cover plate) and the second body. The shape of the outer surface of the fixed body (corresponding to the hinge body of the second body or a slightly thicker plate-like body than that of the existing patent has a triangular prism shape) is completely different, and the inner space on the cover plate is completely different. As it is not reflected, the components of the control unit cannot be applied, so it is applied collectively to the fixed body. Garda.

Currently, smartphone users want to meet conflicting requirements such as large screen, high portability, sufficient battery capacity, light weight and thin thickness, and also include wireless or wired earphones, auxiliary batteries, wireless chargers, navigation, Currently, one or more of auxiliary devices such as black boxes, AI speakers, and action cameras are used together with a smartphone.

Among these auxiliary devices, the importance of the AI speaker, which has strong voice recognition and voice answering functions, is increasing in importance, and its application is also expanding in the automobile, office, and home areas.

On the other hand, among the smartphones that users carry for most of the day and are mainly used for information retrieval, call and text transmission, e-mail and camera shooting, AI is applied to voice recognition and camera shooting functions on expensive smartphones, but it is plate-shaped Due to its structure, it is not a substitute for AI speakers despite its high specification compared to AI speakers.

Therefore, the present inventor uses a flexible display to simultaneously realize the screen display and sound generation in the front direction of the screen display regardless of the folded and unfolded state, and is formed when the body is folded, not a two-dimensional simple folding in the form of a plate. A foldable video display device having both portable characteristics of a foldable device, AI speaker function, and video display device function is proposed below by applying a speaker to a 3D variable space.

1 is a conceptual diagram of a folded state of the foldable image display device.

As shown in FIG. 1, when a foldable image display device to which the flexible display 10 is applied is capable of forming a variable space in a folded state and a variable space disappearing when unfolded, a two-dimensional, two-dimensional folding of a simple plate shape is possible. In addition, it should be a three-dimensional fold that forms a cylinder or prismatic column.

In the case of a simple plate-shaped two-part two-dimensional folding, there is a disadvantage that a limited triangular prism can be folded only when the ground is used.

Among the three-dimensional folding, the folding of the cylinder can be implemented only when all components including the body, the control unit, and the battery are flexible, in addition to the flexible display, and there is a problem of maintaining the cylinder during folding and maintaining the plane when unfolding.

Folding of a prism over 4 prism has the advantage that it can be realized if only some components, including a flexible display and a connecting board, are flexible, but the body is divided into four or more parts, making it difficult to secure effective space for control and battery application and difficult to control folding and unfolding. The problem exists.

However, the triangular prism has the advantage that can be realized if only some components, including the flexible display and the connecting board, are flexible, and the body is divided into subdivisions, so it is easy to secure space for control and battery application, and it is not difficult to control folding and unfolding. In addition, unlike the case of two-part two-dimensional folding, it has the advantage of being able to achieve structural stability, which is a unique characteristic of the triangular column itself when folded.

In addition, when forming a triangular prism, it has the advantage that two or more sides with different orientations are maintained in an exposed state, and when a speaker is applied to a triangular column-shaped variable space, the variable space is used as a resonance chamber. It also has the added advantage of enhancing bass characteristics.

This may be an alternative solution to the disadvantages of bass generation when using a flexible display as a sound generating means.

The present inventor can freely fold and unfold the body capable of realizing the variable spatial features of the triangular prism shape, and use a part of the screen display surface as a diaphragm area to generate sound together with the screen display in the front direction of the screen display surface. In addition, an embodiment of a foldable image display device capable of monitoring a camera in two directions or more and inputting a voice command is provided using the drawings.

It has a shape including.

FIG. 50 is a plan view of the folded state of FIG. 4 showing a difference depending on whether an inclined surface 1 and a grip surface 1 are applied to the first body and the third body, and a difference according to a folding angle.

The concept of the inclined surface 1 116 and the grip surface 1 117 of FIG. 50 also applies to the embodiments of FIGS. 2, 3 and 5.

As shown in FIG. 50, when the inclined surface 1 (116) is applied to the first body (101a) and the third body (101c), the hinge axis of the first body (101a) and the third body (101c) is not applied. As shown in the figure, the dimension of the part perpendicular to the direction is increased by “beta”, and as a result, the dimension of the screen display surface is increased.

In addition, when the inclined surface 1 (116) is applied to the first body (101a) and the third body (101c), the effect is mutually supported when the first body (101a) and the third body (101c) are simultaneously folded than when they are not applied.

On the other hand, as shown in FIG. 50, when the folding angle Y of the first body 101a and the third body 101c is changed to 65 degrees greater than 60 degrees forming an equilateral triangle, the first body 101a and the third body ( It can be seen that the dimension of the portion perpendicular to the hinge axis direction of 101c) increases, which results in an increase in the dimension of the screen display surface.

However, when the folding angle (Y) is increased to 65 degrees larger than 60 degrees forming an equilateral triangle, the grip surface 1 (117) distance from the hinge axis increases when the first body (101a) and the third body (101c) are simultaneously folded. It has the disadvantage that the user is inconvenient to grip by hand.

In addition, when the folding angle (Y) is smaller than 55 degrees, there is a disadvantage in that the angle of the erected part is too low to perform when the notebook-type over-extension is performed, and there is also a problem in that the variable space 700 is reduced to the point that it has no utility value. do.

Conversely, if the folding angle (Y) is greater than 65 degrees, it may cause a problem of gripping with one hand and inconvenient to grip.

Therefore, the folding angle of the embodiments of the present invention is applied to maintain 55 degrees or more and 65 degrees or less.

The first body 101a to which the hinge-related shape is applied to the corner portion, the flexible display 10 is fixed or supported, and the second body 101b and one end of the edge hinged to the first body 101a and the end of the hinge shaft It is coupled to the optional engaging action part (not shown) and the optional engaging action part which are assembled and applied to any one of the grip faces which are the externally exposed surfaces of the first body 101a or the second body 101b perpendicular to the It comprises a locking projection (151a, 151b or 241) to form an engaging and applied to the adjacent grip surface of the grip surface to which the optional engaging action is applied.

The optional engaging action part is assembled and applied on the basis of the rotation axis in a rotatable state, and one end portion comprises a rotating engaging plate 150 or 240 in which the shape of the engaging forming part which selectively forms the engaging protrusion is reflected and the engaging protrusion ( 151a, 161b or 241) has a feature that is applied separately to one or more grip surfaces by varying the distance from the hinge axis.

To the grip surface to which the rotation locking plate 150 or 240 is applied, a protruding prevention shape 152 or 242 is applied in order to prevent the grip surface area of the rotation locking plate 150 or 240 from departing and to limit the rotation direction.

65 and 66, the distance between the rotation center axis and the hinge axis of the rotation locking plate 150 or 240 is fixed, and the distance between the hinge axis and the locking projections 151a, 151b, or 241 is also fixed and rotational. The distance between the central axis of rotation of the plate 1 (150) and the end forming portion on the opposite side is also fixed.

When the end jamming portion of the rotating locking plate 150 or 240 is switched to a state in which the locking projections 151a, 151b, or 241 are engaged, the rotation center axis, the hinge axis, and / or 241 of the rotating locking plate 150 or 240 are formed. Since the triangles are completed and each have a fixed constant distance, it is impossible to change the state including rotation of the first body 101a or the second body 101b, unless the rotation of the rotating locking plate 150 or 240 is released. Even when the external force including the action is maintained unfolded state.

In addition, as shown in FIGS. 65 and 66, the rotation directions of the rotation locking plate 150 and the rotation locking plate 240 are different from each other, which is due to the protrusion preventing shape 152 or 242.

In addition, the rotating locking plate 150 or 240 is applied to the grip surface of the second body 101b so that the rotational force of the user can be rotated only when external force is applied to the rotating locking plate 150 or 240. Alternatively, an inclined locking jaw (not shown) formed to a height lower than the thickness of 240 is preferably formed at the front portion of the rotation start.

The rotating locking plate 150 rotates toward the screen display surface side when forming a jam, and the rotating locking plate 240 rotates toward the body inner surface 2 211 side when forming the jam.

On the grip surface to which the rotating locking plate 150 is applied, the locking forming portion of the rotating locking plate 150 released from the locking projection 151a is guided by the folding rotation of the first body and performs a function of rotating to a storage position. The shape of the rotating stop plate guide 244 is formed to protrude to a certain length.

68 is a conceptual view showing that the embodiments of FIGS. 3 and 5 in which the sliding opening is formed on the grip surface 1 can provide a wider display screen than the embodiments of FIGS. 2 and 4.

2 and 4, unlike the foldable image display device of the embodiment of FIGS. 3 and 5, the sliding opening 108 is not applied, so that the sliding plate 300 has a grip surface 1 I cannot escape (117).

On the other hand, in the foldable image display device of the embodiment of FIGS. 3 and 5, the sliding circumferential portion of the hinge circumferential surface, which is generated when folded out of the grip surface 1 117 and dissipated when unfolding, is opened bezel cover 1 ( 400), allowing a wide display screen as shown in FIG. 68 by naturally exposing it without hiding it.

69 is a conceptual view showing that the embodiments of FIGS. 2 to 5 can be utilized in various states.

The use examples shown in FIG. 69 are possible because the foldable image display device according to the embodiment of the present invention has a structure in which two hinges are applied, rather than a single hinge, and a notebook-type over-expansion is possible.

Also, although not shown, it is possible to fold in response to the curvature of the hip even if it is put in an open state on the back pocket of the pants, so there is no risk of damage if it is not placed in the back pocket of the pants, such as a plate-shaped image display device.

70 is a perspective view and a plan view showing that a wireless earphone and a touch pen can be applied to the variable spaces of the embodiment of FIGS. 2 to 5.

As shown in FIG. 70, the foldable image display device of the embodiments of FIGS. 2 to 5 is a Bluetooth earphone (in addition to the function of utilizing the variable space 700 formed in the collapsed state and disappears when unfolded as a bass resonance of the AI speaker) 710) and the folding touch pen 720 may be used as a storage space.

In order to use the Bluetooth earphone 710 stored in the variable space 700, the Bluetooth earphone 710 fixed to the elastic storage band 191 applied to the inner side 1 (111) side of the body after switching to the unfolded state. Just take out and use.

When this method of use is applied, there is no need to carry a separate Bluetooth earphone case, and the convenience of being able to immediately use the storage is also obtained.

71 is a conceptual view showing that the variable space and the sliding plates 300a and 300b applied to the embodiments of FIGS. 3 and 5 perform heat dissipation functions.

As shown in FIG. 71, the variable space 700 may perform a function of a passage that discharges heat generated from the control unit and the battery in addition to the resonance cylinder function and the storage space function.

In the case of being folded in close contact without forming a variable space, the space in which heat is discharged is limited when gripped by hand in the folded state, but the foldable imaging device of the embodiments of FIGS. 2 to 5 in which a variable space in the form of a triangular prism is formed It shows that it has excellent heat dissipation function because it has a structure that can be ventilated in the central part even if the user is gripping it.

In addition, in the embodiment of FIGS. 2 and 4, the sliding plate 300 is trapped in the inner spaces of the first body 101a and the third body 101c to discharge heat generated by the control unit of the inner space 1 104. Although the function is limited, the sliding plates 300a and 300b of the embodiments of FIGS. 3 and 5 have one end at a relatively cool area outside the first body 101a and the third body 101c, and are controlled by the control unit. It acts as a heat dissipation transmitter to dissipate the generated heat.

FIG. 72 is a conceptual view showing that an unadhesive portion of a flexible display rises and rises when an external force is applied to the sliding moving plate applied to the embodiments of FIGS. 3 and 5 using a palm.

As shown in FIG. 72, the foldable image display device according to the embodiments of the present invention shown in FIGS. 3 and 5 releases the gripped hand and touches the finger even when the grip is performed without touching the screen display surface. It shows a use case that can be used for navigation without manipulation.

The flexible display 10 is provided with a foldable function and a pressure sensing touch panel (not shown) for detecting a pressure change when the screen is touched, and the first body 101a or the third body 101c is fully flattened. In the state, if the end of the sliding plate 300a, 300b protruding out of the grip surface 1 117 via the sliding opening 108 is pressed to the hinge side using the inner surface of the palm that the user was gripping, the rear sliding area 1 The pressure sensing touch panel detects a pressure change due to the raised curved surface formed in the non-adhesive portion of the flexible display 10 located in the 145 or the rear sliding area 2 146, and transmits it to the control unit.

The control unit that detects the user's event by pressing the end portions of the sliding plates 300a and 300b has the input value of the sliding plates 300a and 300b caused by rotation of the first body 101a or the third body 101c. ) If there is no significant rotation input of the first body 101a or the third body 101c input from the hinge axis rotation detection sensor 135 by comparing and determining whether the movement is an input value, the sliding plate 300a independent of the sliding movement , It is determined that the momentary end is pressed in 300b) and an event routine is executed for the momentary end-pressing event.

The concept applied to FIG. 72 is also a function in which the sliding plate 300a, 300b absorbs the drop impact in the direction of the hinge and retreats when the drop to the edge of the sliding plate 300a, 300b occurs in a fully flattened state. It also has the side effect of increasing the resistance to drop impact by acting.

73 is a conceptual diagram showing that the hinge axis rotation detection sensor can detect the amount of rotation when a rotational force is applied to either the first body or the third body in the fully flattened state of the embodiments of FIGS. 3 and 5.

As shown in FIG. 73, the foldable image display device according to the embodiments of the present invention shown in FIGS. 2, 3, 4 and 5 grips the first body 101a and the third body 101c with both hands. After the user is disengaging the rotation locking plate 240 on one side to enable selective rotation, the user may use the hinge axis rotation detection sensor 135 applied to the substrate support application unit 105 to allow for rotation. It detects the rotational displacement in the upward direction of the display surface or the rotational displacement in the downward direction, detects whether or not the displacement state persists, and transmits it to the control unit, thereby performing navigation by bending the palm itself, not navigational manipulation by touch manipulation. Makes it possible.

74 is a conceptual diagram showing that the edge of the flexible display that is not fixed when the over-unfolding is rotated causes a sliding movement due to overlapping of the hinge region.

As shown in FIG. 74, in the case of a single hinge-applied image display device having a hinge radius R similar to the body thickness T, the creation and disappearance of the circumferential surface of the hinge occurs when folded and unfolded, and accordingly, the bezel gap K The sliding movement of the end of the flexible display occurs in the inner part of the inner body.

When switching from the folded state to the fully flattened state, the sliding amount (A) has the following relationship, and when the hinge radius (R) or the folding angle (Y) is reduced, there is a property that it decreases in a fixed rate.

Amount of sliding (A) = hinge radius (R) x folding angle (Y)

In addition, after the fully flat unfolded state, in the excessive unfolded state of the notebook type, additional sliding movement of the end of the flexible display 10 occurs due to overlapping of the hinge region of the circumferential surface of the hinge, so that the end of the flexible display 10 has a bezel gap (K ) Occurs.

The amount of sliding of the over-expanded sliding (C) does not establish a constant relationship with the hinge radius (R) or the over-expanding rotational angle, but has the characteristic that the amount of overlapping of the hinge region increases as the over-expanding rotational angle increases.

The over-expanded sliding amount (C) in FIG. 74 is indicated as 2C rather than C, indicating that the over-expanded sliding amount is accumulated on the opposite side of the body because the over-expanded sliding is impossible to either body. If it is possible to over-slip evenly across all of them, it should be generated and marked as half of the value of C at the end of each body.

In addition, there is a problem in that the circumferential surface of the hinge is protruded and maintained at the bottom of the hinge portion in a fully flattened state, and there is a problem in exposing the discontinuous portion in the hinge region. .

Unlike FIG. 74, the foldable image display device 1 shown in FIGS. 2, 3, 4, and 5 adopts a tent-type folding of an obtuse angle rather than a 180-degree full folding to reduce the folding angle (Y) by 1/3. Due to the degree of reduction, the amount of sliding (A) at the end of the flexible display 10 is reduced by 1/3.

In addition, the foldable image display device 1 shown in FIGS. 2 and 3 also reduces the hinge radius R relative to the thickness of the body, thereby reducing the amount of sliding movement A by the hinge radius R reduction ratio. Additionally.

In addition, the foldable image display device 1 shown in FIGS. 2, 3, 4, and 5 also reduces the amount of overlapping of the hinge region as the amount of over-sliding sliding movement C and the hinge radius R decrease. There is no reduction characteristic.

In addition, since the folding method, which reduces the hinge radius (R) and the folding angle (Y) by about 1/3 of the body thickness, is applied, the discontinuous exposed portion generated at the end portion of the hinge shaft is also reduced.

The embodiments of the present invention have been described above with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features of the present invention.
