Description

Multi-stage foldable display device that resolves seams

The present invention relates to a multi-stage foldable display device that solves the problem occurring in the seam portion, and more particularly, when a plurality of display devices having individual display screens are connected to each other to implement one panoramic screen, adjacent display devices. The present invention relates to a multi-stage folding display device that can be carried by solving a problem in which a screen gap is widened and some screens are covered at seams of the liver.

Although attempts to enlarge the screen of a computer-based portable communication device have been made early on, but increasing the screen size makes it difficult to carry. On the other hand, when the screen size is smaller, the portability becomes more convenient. There was a disadvantage resulting. In order to solve these drawbacks, attempts have been made to apply the technology to connect the screens of multiple display devices, which are becoming more common in desktop computers and multiple video systems, to realize one large panoramic screen to portable devices.

As an example of implementing a panoramic screen in a multi-folding manner in a mobile device, international patent WO2010028394 is disclosed as a prior art document, but in this prior art document, the screen is encroached at a seam portion connecting the respective screens of the display devices. It failed to commercialize and commercialize in a form that exposes serious problems of gaps. It was technically possible to implement a single large panoramic screen by spreading multiple hinged display devices, but the gap between the screens was widened at the seam where the individual screens of the display devices were connected to each other, so that the seamless panoramic screen was not realized. It is causing a problem. In addition, the problem is that the screen is obscured by a bezel made of an opaque material that extends along the seam, which further exacerbates the panorama screen. In addition, due to the nature of the folding display device that is connected by folding and folding, the problem of electrically connecting the seam part, which is an extremely tight space where the free rotation of the hinge is repeated, remains a difficult problem to solve. The problem of maintaining the flat plane structure when the individual display devices are unfolded to realize the screen is also a difficult task to consider along with other designs due to the nature of the portable device.

That is, the conventional method does not solve this problem, causing the screen gap to be widened at the seam where the display devices are connected to each other, and also causing the screen to be hidden, and the gap between the screens called gaps. The occurrence problem is not a big problem in the built-in multi video system, but it is a big problem in the practical use of a portable small folding display device having a compact structure. In addition, there is no free space in the joint area where the individual display devices are closely connected to each other, and rotational movement occurs repeatedly, thus protecting the inside of the device unless the problem of connecting various cable lines electrically connecting each display device is solved. In addition to making the design of a rigid cover device difficult to do, it can further increase the screen separation problem of the seam, and make the thickness of the overlapping display devices become thicker, making it more practical to use. The problem of power connection through seams in the field has not yet been specified.

In addition to these problems, the problem of disposing the battery and power control device for power supply for driving each display device is not practical, which complicates the design problem of the entire folding device with the cable line connection through the seam. There was a difficult design problem. These problems have been a serious obstacle to efforts to implement a single consistent panoramic screen by connecting individual display devices by hinges, and have been a problem that prevents the commercialization and commercialization of the product.

The screen naturally To provide a multi-stage folding display a seamless troubleshooting apparatus so as to be to the purpose.

In addition, the present invention, by configuring a flat holding member for maintaining the unfolded state of the display devices adjacent to each other, the wide spread state in parallel when each display device is spread in a flat plane to implement a panoramic screen Of the display device can be used as it is, even if the display device is positioned at any angle or any external movement, so that the unfolded display screen can be used as it is without being folded. Another object of the present invention is to provide a multi-stage foldable display device, which can be implemented, in which a seam problem is solved.

In addition, the present invention, by configuring the folding holding member, so that the folded overlapping state of the display devices adjacent to each other can be firmly fixed, and displayed in the inner space of the border area outside the visible area of the display device By connecting the connection for the electrical connection between the devices, the joint problem is solved, which does not interfere with the rotational movement of the shortened hinge member and enables the design of a rigid cover device without increasing the thickness of each display device. Another object is to provide a foldable display device.

In addition, according to the present invention, by forming a connection connection portion of a cable-free connection method or a connector method, the rotational motion of the hinge member is repeatedly generated, and in addition, a variety of electrical parts are formed at the extremely narrow seam part of the existing space. The problem of passing the connecting line is solved. As all the cable lines are gathered and passed through the inside of the rim area, various cable lines can be reliably connected without any obstacle to the pivoting motion of the hinge member and the cover design of the display device. Another object of the present invention is to provide a multi-stage folding display device that solves a seam problem, which simplifies a power supply line problem in a multi-display device, and enables a more convenient operation by simplifying a control method.

In addition, the present invention, when the plurality of display devices can be rotated to overlap the combination, the arrangement of the single-axis hinge member for the rotational coupling is sequentially arranged on the front and back, and each hinge is opened and closed The direction is reversed to each other sequentially, so that an infinite number of display devices can be superimposed, and a transparent and durable cover member or a bezel design is adopted for the seam jointed between the plurality of display devices. Accordingly, another object of the present invention is to provide a multi-stage folding display device in which a seam problem is solved, so that a seamless panoramic screen can be realized by removing a part of the screen that is generated at the junction part.

In the three-stage folding structure, since the structure in which the first display device 110 can be used alone in a folded state is more practical, the first display device 110 becomes a structure in which the front portion of the first display device 110 is exposed to the front. ) And the second display device 110 is provided with a shortened hinge member 120 is installed on the back to correspond to each other, the second display device 110 and the third display device 110 is a shortened hinge member ( 120) is installed to be folded and unfolded structure. In the case of three-fold folding, when the screens are fully opened, the panoramic screen is unfolded from the front and functions as a tablet PC.

Multi-stage folding display device 100 according to an embodiment of the present invention has a two-stage structure that can overlap and unfold the two display devices 110 shown in Figure 4, and three display devices 110 shown in FIG. It includes a three-stage structure that can overlap and unfold), in addition to the display device 110 including a large number of four or more stages can be combined freely to implement a folding device. As a result, a compact portable display capable of a hybrid function for realizing a wider screen by folding the display device 110 for convenient use and carrying out a wider screen in parallel when a wider screen is needed. The device can be implemented. Here, the display apparatuses 110 generally refer to a computer screen display device as a device for visually displaying data. As an example, a small / portable computer such as a laptop or a computer may include a flat screen type display device such as an LCD display or a plasma display, and may be superimposed to implement a folding structure of multiple displays. Applicable to display devices of appropriate thickness.

FIG. 6 is a view illustrating a rotational coupling direction with a shortened hinge member in a three-stage folding display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention. As shown in FIG. 6, the three display apparatuses 110 have a coupling structure that is sequentially rotated and folded in a lateral direction to each other, and are arranged alternately on the rear and front surfaces of the respective display apparatuses 110. Of course, the order and arrangement of the other than the form shown in Figure 6 is apparent that can be easily changed by those skilled in the art design.

FIG. 7 is a partial enlarged view illustrating a pivoting structure of a shortened hinge member in a folding multi-display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention, and FIG. 8 is an embodiment of the present invention. In the folding multi-display device of the multi-stage folding display device that the seam problem is solved according to the present invention, there is shown a partial enlarged view of the connection structure is implemented in close contact with each other without a gap caused by the shortened hinge member. As shown in FIG. 7 and FIG. 8, the shortened hinge member 120 is installed in a pair at an upper side and a lower side of an adjacent display device 110 to operate to rotate. The shortened hinge member 120 is provided with a first support plate 121 on the upper plane of the edge region 111 of one display device 110 of the adjacent display device 110, the first support plate 121 The second support plate 122 is installed on the other display device 110 at a position corresponding to the first display plate 110 and the adjacent display device 110 on which the second support plate 122 is installed is coupled to each other. The first support plate 121 and the second support plate 122 is configured to include a rotating shaft 123 coupled to face each other so as to be rotated. That is, the structure in which the first support plate 121 and the second support plate 122 are rotatable through the rotation shaft 123 is a circularly rotatable holder (not shown) for the first support plate 121 and the second support plate 122, respectively. ) Is formed on the same axis, it can be implemented by inserting the rotary shaft (123). This single pivot hinge system plays an important role in eliminating gaps in seams.

9 is a view showing a side view when the three-stage folding display device of the multi-stage foldable display device solved the seam problem according to an embodiment of the present invention fully deployed, Figure 10 is an embodiment of the present invention 3 is a view illustrating a side view when the three-stage folding display device of the multi-stage folding display device in which the seam problem is solved is completely folded. 9 and 10, when the multi-stage folding display apparatus 100 according to the present invention comprises three display apparatuses 110, a main battery 113 is provided inside the first display apparatus 110. The secondary battery 114 is disposed inside the second display device 110, and the remaining third display device 110 adopts a structure in which a separate battery is not installed, thereby reducing the overall weight and wiring layout. This simplifies and simplifies power control.

On the other hand, the use of the shortened hinge member 120 has the advantage of forming a close structure without physical separation between the display device 110, but the structure of the display device 110 unfolded when gravity or external movement occurs May cause unintended dismantling. That is, considering that the characteristics of the foldable display apparatus 100 are mostly portable, a part or all of the spread screen is not disturbed even when various positions change or any external movement occurs in the use of the display apparatuses 100. Maintaining constitutes a very important problem in practical use. Conventionally, a dual pivot hinge system structure without a separate fixing device in order to maintain an expanded coupling structure when a plurality of hinged display devices are unfolded for a larger panoramic screen is realized. However, this conventional integrated solution solves the problem by causing the hinge rotational movement to bend the joints where the display devices come into contact with each other, resulting in serious side effects such as the gap between the visible screens when implementing the panoramic screen. Had a devastating effect on Accordingly, in the present invention, a separate rail groove structure is formed on the upper side edge of the shortened hinge member 120, and a latch for fixing or dismantling the physical structure of the unfolded display device 110 by freeing forward and backward over the rail groove. It is intended to solve by installing a flat holding member 130 having a flat bar-shaped configuration to play a role.

11 is a view showing a perspective view of a flat structure fixing member of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention, and FIG. 12 is a seam problem according to an embodiment of the present invention. The internal structure of the flat holding member of the multi-stage folding display device is shown in cross-sectional view, Figure 13 is prevented from falling inside the flat holding member of the multi-stage folding display device solved the seam problem according to an embodiment of the present invention It is a figure which shows the enlarged perspective view of a structure. 11 and 12 illustrate that the display device 110 corresponding to the rotating part of the three-stage folding display device 100 is unfolded in a flat shape without being disassembled even when gravity or external movement or flipping when the display device 110 is unfolded in parallel. The structure of the plane holding member 130 for holding is shown.

As shown in FIGS. 11 and 12, the flat rail-shaped bar 132 that is free to move above the engraved rail groove 131 on the side border region 111 where the shortened hinge member 120 is located is a shortened type. It moves to the seam side portions of the two display devices 110 connected by the hinge member 120, and functions to lock the two display devices 110 so as not to open, and if necessary, opens the latch to unlock the function. . The rail-type flat holding member 130 can be installed on the side where all the short-type hinge members 120 are located, and the lock-type function for releasing the single-sided hinge member 120 can be arbitrarily moved and a release function for releasing the lock. While performing the display device 110 to perform the tablet PC function to implement a panoramic screen. Accordingly, the rail-shaped bar 132 is a configuration of one locking and unlocking introduced for the purpose of freely fixing and detaching the unfolded display device 110, and the respective display devices 110 are combined to form a wide screen. In order to implement the configuration to make it possible to maintain the unfolded state of the multi-stage display device 110 unfolded in an unstable structure. As a result, the plane maintenance and plane release of the display apparatuses 110 caused by the free rotation of the shortened hinge member 120 may be solved.

On the other hand, the rail-shaped bar 132 having a latch function performs a simple and convenient locking and unlocking function, but due to the characteristics of the rail-shaped structure may be easily slipped at an inclined angle and the locking state is randomly released. Will be. Therefore, as shown in FIG. 12, a non-slip structure is attached to the bottom of the rail-type bar 132 to prevent the bar from slipping, and to prevent the flow down by using two methods in combination. It is composed. That is, the U-shaped spring 133 is configured to be fitted into the rail groove 131 at the lower end of the rail-shaped bar 132 so as to be in close contact with the upper and lower surfaces thereof, and the U-shaped spring 133 and the rail type are formed. A pair of anti-skid structures 134 mounted on the bottom of the horizontal bar 132 are attached in a flat geared manner so that the display device 100 unfolded by the gears 135 engaged in a male and female manner may be at any angle. Since the mold bar 132 does not flow down, the flat state of the unfolded display device 100 can be maintained firmly.

As shown in FIG. 12, the spring 133 having a U-shape and a U-shape that is horizontally inverted when viewed in cross section is structured so that the repulsive force is directed to the outside so as to surround the spring 133. A friction force is generated with the upper and lower surfaces of the 131 to cause the rail-shaped bar 132 not to flow down. In addition to the frictional force, as shown in FIG. 13, a pair of non-slip structures 134 mesh with each other in the form of teeth 135 formed up and down, and perform a locking and unlocking function to rail grooves 131. The rail-shaped bar 132 moving on the above can be firmly fixed without flowing down at any angle. That is, the moment the finger presses the finger pressing plate 136 to move the rail-shaped bar 132 to the rail-shaped bar 132 the moment the force is transmitted to the spring 133 and the rail groove 131 At the same time, the gap between the non-slip structure 134 is opened together and the fixing is released to unlock the rail-shaped bar 132 is free to move forward and backward. At this time, when the rail-shaped bar 132 is advanced to pass the seams of the display device 110 and then lifts a finger to stop, the spring 133 and the rail groove 131 and the spring 133 and the non-slip The structures 134 are engaged with each other with narrower spacing so that the rail-shaped bar 132 is fixed. When the rail-shaped bar 132 is fixed without moving, the unfolded display devices 110 are also maintained without being dismantled. Accordingly, the screen of the unfolded display devices 110 is maintained at a flat state without being disassembled at any angle. Due to the use of such a locking device can be expanded to maintain the state of the display device 100, the panorama screen is implemented, and can be easily and easily dismantled and folded whenever necessary. FIG. 13 shows a structure in which the non-slip non-slip structure 134 meshes with the planar teeth 135 facing each other up and down.

14 is a cross-sectional view showing the concave-convex structure and the position of the folding holding member for fixing the overlapping device in the three-stage foldable display device of the multi-stage foldable display device solved the seam problem according to an embodiment of the present invention; 15 is a perspective view illustrating a position and a shape of a folding and holding member for fixing when folded in a two-stage folding display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention. As shown in FIG. 14, the folding holding member 140 may be configured to prevent the three-fold folding multi-display device 100 from being unfolded arbitrarily when the three-stage folding multi-display device 100 is folded. That is, when folded to the upper or lower portion of the edge region 111 is formed a fastener 141 and a fastening groove 142 to be engaged with each other like a male and female in a position to be coupled to each other to form a structure that is engaged with each other. Since this is a detachable method, no separate control is required when using. Such a folding and holding member 140 prevents a problem caused by inconvenience in using the display apparatus 110 when the plurality of folded display apparatuses 110 are unfolded arbitrarily and folded when the display apparatuses 110 are folded. It will function to keep the shape fixed.

That is, the folding holding member 140 has a rear edge region of the second display apparatus 110 adjacent to the fastener 141 protruding from the center of the rear edge region 111 of the first display apparatus 110. The first display device 110 and the second display device 110 is engaged with each other when the display device 110 is folded to correspond to the fastening groove 142 engraved into the groove structure in the center of the Is fixed. Similarly, the fastener 141 protruding in the center of the front edge region 111 of the second display apparatus 110 has a groove in the center of the front edge region 111 of the third display apparatus 110 adjacent thereto. The second display device 110 and the third display device 110 are meshed with the fastening groove 142 engraved in the structure to be fixed to each other.

FIG. 16 is a view illustrating an electrical connection method of a three-stage folding display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention. As illustrated in FIG. 16, the electrical connection in the three-stage display device 110 is electrically connected to a neighboring display device 110 through an inner space of the upper and lower edge regions 111. That is, various cable wires 151 pass through the inside of the edge region 111 that functions as a bezel, so that the physical structure that is in close contact with the seam may be maintained without disturbing the cover design of the display device 110. As a result, a smooth panorama screen can be realized. In particular, the method of passing the various electric wires to the joint portion connected to the inner space of the rim while connecting the display device 110 to the hinge member 120 outside the pivot axis is very important for practical use of the folding display device. It is a problem, but the existing method does not specify the electrical connection method in detail. The display device 110 is in close contact with the joints connected to each other by the hinge, there is no free space, and because the rotational movement repeatedly occurs, the electrical connection problem was not easy to solve. If each display device 110 is not electrically connected smoothly, the meaning of the foldable device disappears, and even if the electrical connection is possible, the gap is increased at the joint portion or the cover design of each display device 110 is negative. If it causes an effect, it becomes a big problem in practical use. In the present invention, the inner space at the top and bottom of the border region 111 surrounding the display panel for the electrical connection of each display device 110 that must pass through the seam in the constraint of maintaining a compact environment The connection method is adopted. The electrical connection method using the inner space of the upper or lower portion of the border area 111, which is an inactive area that is not visible to the user when the display image is output without using the rear or side space of the display panel, is important for implementing a folding display device. One of the elements. Due to the structural constraints of compact portable devices and the nature of foldable devices requiring close spacing at the seam, when cable cables pass through the cover side of the display device, the cover design to protect the inside of the device becomes difficult, and It is more likely to interfere with the hinge rotation or cause more gaps between the screens, and to increase the thickness of the display device.

However, the cable line connection method through the inner space of the border region 111 formed at the edges of the top and bottom of the multi-display device 100 in the present invention does not interfere with the cover design of each display device, and also the seam portion This will also prevent the possibility of further screen spacing. In the present invention, the edge region 111 has various important functions, and thus needs to be specified and passed in detail. The edge region 111 is connected to each display device 110 by a shortened hinge member 120. Physically, one large plane is a region connected to each other by its outer edges. It is a generic term for inactive areas except areas that are visible when an image is output to the screen. The edge region 111 is made of a hard metal material and functions as a cover for protecting the inside of the device, and functions like a bezel of a multiple video system. In the present invention, the single-sided hinge member 120 and the flat holding member 130 are mounted on the edge region 111, and various cable wires 151 for electrically connecting each independent display device 110 through an inner space. ) Is designed to pass through.

FIG. 17 is a cross-sectional view of an electric wire passing through a non-cutting method in a joint portion of a folding multi-display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention, and FIG. 19 is a view illustrating a structure in which a cable line bundle of a connection connection part of a multi-stage folding display device, in which a seam problem is solved, is pulled by a spring installed inside an edge region to contract and relax, and FIG. 19 is a view of the present invention. FIG. 20 is a cross-sectional view illustrating a cable line bundle of a multi-stage folding display device in which a seam problem is solved according to an embodiment and is passed in a twisted shape in an edge region, and FIG. 20 illustrates a seam problem according to an embodiment of the present invention. Of three-stage foldable display device of multi-stage foldable display device FIG. 21 is a perspective view illustrating a connector type electrical connection structure in a new portion, and FIG. 21 is a radius of curvature of a terminal in a connector type electrical connection structure of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention. 22 is a cross-sectional view formed in the shape, Figure 22 is a combination of three inner terminal grooves and the outer terminal portion for the electrical connection inside the connector of the multi-stage foldable display device solved the seam problem according to an embodiment of the present invention It is a figure which shows a structure in sectional drawing. 17 to 22 illustrate various implementations of an electrical connection method between display devices of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention.

FIG. 17 is a cross-sectional view illustrating a bundle of various cable wires 151 passing through the inner space of the edge region 111 and passing through the seam portion, and passing through the seam portion when the display device 100 is unfolded and folded. The length of the electric wires are long and shortened, which causes a lot of problems in the practical use of the foldable display device 100. That is, the length of the cable wire 151 is stretched and stretched at the seam portion and then decreases as it returns to its original position according to the rotational movement of the shortened hinge member 120. This may cause a problem. This is because the cable line 151 extending from the seam may interfere with the rotation of the hinge member 120 or may cause a gap between the display devices 110. This problem can be solved by mounting a spring device that gently pulls the cable wire 151 in the inner space of the edge region 111. FIG. 18 shows that when the bundle of cable wires 151 is formed in the joint portion by the pivoting motion of the hinge member 120, the spring 153 installed inside the edge region 111 is extended to adjust its length. When the extended length is contracted again by the rotational movement, the spring 153 is pulled to lengthen the length of the cable wire 151 in the inner space of the edge region 111, and then the shortening movement is repeated. The line 151 does not interfere with the rotation of the hinge member 120.

19 is a problem in the seam portion because it occurs at the same time inside the display device 110 on both sides of the wire bundle length passing through the seam portion can be a bundle of wires alone or together with the spring 153 structure When twisted like a spring and passed through the inside of the edge region 111, it becomes like a connection line of a telephone transceiver and shows an example configuration that can flexibly respond to contraction of the wire length occurring at the seam.

In addition, as another connection method passing through the seam portion of the adjacent display device 110, as shown in FIGS. 20 to 22, the cable line 151 is disconnected from the seam portion. In other words, when folded, the electric wire is disconnected, and when necessary, it is a detachable coupling method in which the overlapping devices are engaged and electrically connected to each other only when they are unfolded in a plane. In the connection method using the connector, when the display device 110 is not in use, the power is cut off, and when necessary, only the front display device 110 can be used in the folded state to be electrically connected. There are several advantages, such as possible convenience and power savings. The enlarged view of FIG. 20 illustrates a structure in which the display devices 110 are electrically connected in a manner of being disconnected from the seam and connected only when necessary. That is, the inner terminal groove 155 and the outer terminal portion 156 are coupled to each other like a male and female when the two display apparatuses 110 are connected in a planar manner to realize a panoramic screen by connecting a connector set similar to the USB in the seam portion. Is electrically connected. Specifically, four sets of connectors are used in the three-fold folding display device. In order for the first display device 110 and the second display device 110 to be electrically connected to each other, the first display device 110 may be bonded to each other. The outer terminal portion 156 protruding from the corresponding bonding surface of the second display 110 is inserted into the inner terminal groove 155 and the inner terminal groove 155 in which the groove is formed in the inner direction of the edge region 111 of the second display 110. Form a detachable connection structure with each other. In this pair of detachable coupling structure, the inner terminal groove 155 and the inner terminal portion 156 have a detachable coupling structure in the vicinity thereof, and the inner side of the second display device 110 and the third display device 110 are also connected. The terminal groove 155 and the outer terminal portion 156 are composed of three pairs engaged with each other. The number of such detachable coupling structures may increase according to the expansion of the display device 110.

FIG. 21 has a curvature radius corresponding to the rotation radius such that the structural appearance of the inner terminal groove 155 and the outer terminal portion 156 is naturally combined in the rotation direction of the first display device 110 and the second display device 110. It can be seen that the configuration is implemented in a more practical manner. That is, the inner terminal groove 155 is formed to have a curvature radius corresponding to the inner direction around the shortened hinge member 120, and the outer circumferential surface shape of the outer terminal portion 156 inserted therein also has a corresponding curvature radius structure. By constructing, the first display device 110 and the second display device 110 rotates around the shortened hinge member 120 to form a physical planar structure for implementing the panoramic screen, and the inner terminal groove ( When the outer terminal portion 156 is inserted into the 155 is naturally engaged with each other, the physical structure for the electrical connection is completed. In addition, one inner terminal groove 155 and the outer terminal portion 156 are provided with metal terminals for electrical connection at both sides so that more electric wires can be connected through the inner space of the narrow border region 111. Efficient FIG. 22 illustrates a metal plate connection structure for electrical conduction in the inner terminal groove 155 and the outer terminal portion 156 in the connector system for electrical connection between the display apparatuses 110 according to the present invention. That is, as shown in FIG. 22, the inner terminal metal plate 155b and the outer terminal which are electrically connected through the inner both sides of the three inner terminal holes 155a and the two outer terminal protrusions 156b engaged therewith. When the metal plate 156b is prepared and engaged with each other, a total of six electrical connections are possible through three pairs of detachable / attachable couplings in one connector set. FIG. 22 shows four metal plates provided on each side of the inner terminal hole 155a and the outer terminal protrusion 156a, that is, the inner terminal metal plate 155b and the outer terminal metal plate 156b are each one set as a USB connection structure. Becomes a cable that carries one electrical signal. In addition, since the connector method for electrically connecting the second display device 110 and the third display device 110 is also implemented in the same principle, a detailed description thereof will be omitted.

Is an exploded perspective view illustrating a process of attaching a bezel member of a transparent material to a left side seam of a display device of a multi-stage folding display device in which a seam problem is solved according to an embodiment of the present invention.

23 to 25 are views in which a bezel member 115 made of a transparent material is installed as a cover at a joint portion between a plurality of display apparatuses 110 of the multi-stage folding display apparatus 100 according to the present invention. The bezel member 115 of the transparent material is attached to the right side of the display device 110 as a cover, and a bent portion having an end bent is formed to correspond to the side bonding surface of the second display device 110. The bezel member 115 of the transparent material is combined with the opaque cover of the side to function as a conventional bezel, it is made of a transparent material such as transparent aluminum or industrial sapphire, the interference of the front viewing area of the display device 110 It does not provide an effect. 24 is a view in which both sides of the second display device 110 cover the bezel member 115 of the transparent material with a cover. The second display device 110 is the first display device 110 and the third display device. 110 and the two bezel members 115 of the transparent material such as a-shape a-shape and a-shape horizontally reversed a-shape on both sides of the joint is mounted as a cover to the seam from both sides. FIG. 25 is a view illustrating a bezel member 115 of a transparent material attached to the left side of the third display apparatus 110 as a cover, and a seam is generated on the side of the second display apparatus 110. Only the bezel member 115 of the a-shaped transparent material in which the left and right are reversed horizontally is mounted as a cover. As such, by attaching the bezel member 115 of the transparent material to the joint portion to which each display device 110 is coupled as a cover member, the bezel function is structurally applied to the edge of the front side of each display device 110. The bezel is clearly but visually recognized as being without it, enabling a zero or bezelless design.

This bezelless or frameless design overcomes gaps in the seams caused by hinges in existing multi-display devices, and also eliminates screen bleeding caused by opaque bezels in the seams. The foldable display device can be implemented to smoothly implement the panoramic screen connected to the two screens.
