Description

[0001] The present invention relates to a flexible display apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a foldable flexible display device in which a foldable and unfoldable flexible panel or an electronic paper is applied, more specifically, a flexible panel or an electronic paper having both ends fixed and a central portion supported on the outer periphery of the hinge, It is impossible to absorb the change in the longitudinal direction caused by the change in the circumferential length of the outer circumferential surface of the hinge at the time of folding and to avoid the problem that the central portion protrudes upward when the hinge is extended or that one end is torn due to lack of elasticity when the hinge is folded The flexible panel or the non-fixed portion of the electronic paper can perform its own perturbation by using the elastic force of the flexible panel or the electronic paper according to the folding and unfolding of the hinge.

The display device occupies an important part in an electronic device including an image device and a mobile communication device, and a flexible display device such as a flexible panel and an electronic paper capable of curving and folding in addition to an LCD panel that maintains a conventional plate shape has been introduced .

In applying the flexible display device to the video device and the communication device, a plurality of patents are proposed for a wrapping method in which a roll is wound and stored, and a folding method in which a curved portion is kept at a folded portion while being folded.

In the case of the folding type patent, since the rollers and roller related components are not required unlike the winding method, the image display faces are faced to each other like a notebook, and the flexible display device is fixedly supported inside the case case A number of patents have been proposed. However, there is a problem that the problem of occurrence of the step of the image display surface is not completely solved in the fully opened state, and the folded portion is not protected from the external force while maintaining the curvature.

As another method of the folding method, a patent (Korean Patent Application No. 10-2008-0012667) in which the image display surface of the flexible display device faces directly to the outside and the central portion is directly folded with each other is presented There is a problem that the flexible display device having insufficient stretchability can not absorb the change in length of the portion corresponding to the circumferential length of the folded portion when the portion is unfolded and folded, and thus the sealing state is damaged. A patent that reflects a hinge that absorbs a change in length by applying a spring to one end of a flexible display device that has been redirected to the inner side using a roller inside the edge located on the opposite side of the hinge without directly fixing one end Patent Application No. 10-2010-0062787).

However, the patent which reflects the hinge is that the elasticity of the flexible display device due to the structural limitation that locally acts on the one end of the flexible display device by the spring, Can be destroyed.

In addition, when the hinge is folded and folded, the periphery of the non-fixed portion of the flexible display device is rubbed against the peripheral portion, so that there is a possibility that the sealing state is damaged when using for a long time.

In addition, although a single hinge is applied to only one side of the corner, the application method is unclear even if it is assumed that the hinge is applied to both sides of the edge by expanding the application concept, and a mutual interference avoiding plan should be additionally considered when both hinges are folded at the same time.

Also, since the body constituting the hinge has a thin plate-like shape, it is inconvenient to force the user to hold it by hand or force it to use only a monotonous method of using it on a flat floor.

Unlike the patent in which the above-described hinge is reflected, a link member replacing the function of the hinge is applied to apply a link member in which the link member absorbs a change in length of a portion corresponding to the circumferential length of the corner portion where folding occurs at the folding and folding A patent (Korean Patent Application No. 10-2012-0068710) was presented.

However, the patent to which the link member is applied can accurately absorb a change in length corresponding to the circumferential length of the corner portion where folding occurs only when the link member is in the folded or unfolded state, and during the course of folding or unfolding, Both sides are not always operated simultaneously at the same time, and one of them is operated randomly first, so that it can not absorb the perfect length change and as a result, the sealing condition of the part where folding occurs at the folding and unfolding operation may be damaged.

Also, when different external forces act on the first support or the second support corresponding to the fixed body, unlike the hinge, there is a possibility that the link member is twisted and the related part is damaged.

In the fully opened state, there is no portion that appropriately blocks the ambient light incident from the back surface of the central portion where the link member exists, and there may be a difference in color between the both end portions and the central portion.

SUMMARY OF THE INVENTION The present invention is directed to a folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type folding type There is a problem that the flexible display device at the center portion where the hinge is located when the hinge is operated without protruding upward or tearing at one end due to the lack of elasticity is not caused.

Second, the periphery of one non-fixed end portion of the flexible display device can be protected from external factors when the hinge is operated, so that the peripheral portion sealed state of the flexible display device is not damaged.

Third, in applying each hinge to the edges of both sides for expansion and storage convenience of the image display surface, even if both hinges are folded at the same time, mutual interference is prevented.

Fourth, in addition to the monotonous use mode in which the user grasps by hand or is placed on a flat floor, the user can conveniently use the hinge in various states without applying the supporting force according to the hinge spread state.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terminology used herein is for the purpose of illustrating embodiments of the present invention and is not intended to be limiting of the present invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. In addition, since they are in accordance with the preferred embodiments, the reference numerals shown in the order of description are not necessarily limited to the order.

1 is an exemplary view showing a change in a flexible display device according to hinge spreading and folding.

In FIG. 1, the length L1 of the hinge circumferential surface contacting the flexible display device according to the angle of folding of the hinge is the maximum in the fully folded state, the minimum value in the fully folded state, Follow the formula.

(L1) of the hinge circumferential surface in contact with the flexible display device = hinge radius x folding angle (radian)

If the hinge is folded in a state in which both end portions are closely fixed to each other, a flexible display device having a small stretchability in the longitudinal direction is folded so that the L1 value increases as the folding angle increases and the fixing is not released from either side of the flexible display device It is impossible to avoid the tearing of the flexible display device when it is impossible to fold or when it is forcedly folded.

In order to avoid such a problem, if the flexible display device is released from the side where the electrical connection is made, an electrical connection problem may occur.

On the contrary, if the folded angle is decreased by switching from the fully folded state to the fully extended state, the flexible display device may be lifted up from the hinge portion or the full A problem that the unfolding can not be reached occurs.

In order to solve the above-mentioned problems, a patent (Korean Patent Application No. 10-2010-0062787) having a hinge at one corner has been filed. One end of the flexible display device is maintained in a tightly fixed state, It is not directly fixed at a certain distance from the center but it is changed to the inner side by using the roller inside the corner and then applied to the inner side by applying a spring that applies a tension to one end.

However, the patent reflecting the above-described hinge has a drawback in that the flexible display device is structurally limited due to the normal tension action by the spring at one end of the flexible display device and the one end of the flexible display device is suddenly turned inwardly by using the roller There is a possibility that the sealing state of the flexible display device is broken or the electrical connection portion is damaged.

Also, there is a possibility that the peripheral portion of the flexible display device which is not fixed may be continuously frictioned with the peripheral supporting object when the hinge is operated, and the sealing state of the flexible display device may be damaged during long-term use.

In order to solve the problems of the patent reflecting the above-described FIG. 1 and the above hinge, a patent applying a link member without applying a hinge (Korean Patent Application No. 10-2012-0068710) was filed.

In the patent to which the link member is applied, a link member replacing the function of the hinge is applied, and a method in which the link member absorbs the change in length of a portion corresponding to the circumferential length of the corner portion where folding occurs at the folding and folding is applied .

However, the patent to which the above-described link member is applied has the feature that there are three rotating parts in each link member and two or more of these link members are operated to perform folding and spreading.

Therefore, during the process of folding or unfolding, both of the link members are not simultaneously operated at the same time, and any one of the rotating parts of the link member is operated at random, so that the accurate length change of the folded parts can not be absorbed The sealing state of the portion where the folding occurs may be damaged.

In addition, the above-mentioned patent applying the link member also has a possibility that when the first support or the second support, which is the fixing member of the flexible display device, receives different external force, the link member is twisted unlike the hinge,

Also, the patent to which the above-described link member is applied has a potential safety risk that the folding process of foreign matter may be interrupted or the fingertip may be injured by being stuck on the link member folded like a scissors in the folding operation.

The present invention can be implemented in various cases to solve the problems of the patent reflecting the hinge of FIG. 1 and the patent applied to the link member, The third embodiment and the fourth embodiment are presented, respectively.

In Embodiment 1, a single hinge is applied to one corner, one end of the flexible display device is fixed, and the remaining unfixed portion pierces through the perturbation support object in a direction perpendicular to the hinge rotation axis during the hinge operation, .

3 is a perspective view and a front view of a cover plate according to Embodiment 1 of the present invention, and Fig. 4 is a plan view of a folded state planar view according to Embodiment 1 of the present invention. Fig. And FIG. 5 is an exploded top plan view and a cross-sectional view for Embodiment 1 of the present invention.

As shown in FIGS. 2, 3, 4 and 5, the first embodiment includes a single hinge fixing body 10A having a hinge shape reflected at one corner, a single hinge fixing body 10A having a single hinge fixing body 10A, A flexible display device A (20A) in which one end portion is fixed and the remaining portion that is not fixed is held in a state capable of being folded and unfolded while being supported on the outer peripheral surface of the hinge, And a cover plate A (30A) having a perforation penetration portion (31) and a perturbation protrusion (32) for penetrating and supporting the non-fixed end portion of the flexible display device (20A) , A fixing plate 1 (50) having a central portion removed and one side edge opened so as to press the periphery of the upper surface of the flexible display device (20A) and fixed to the single hinge fixing body (10A) In the body 10A, And a folding detection sensor 60 for sensing folding and unfolding of the hinge.

In order to cope with the change of the L1 value according to the change of the folding angle of the hinge, the first embodiment is a state in which the flexible display device A (20A) is perturbed through the cover plate A (30A) .

To this end, a fixing plate support portion A (11A) having a two-step recess shape is formed on the upper surface of the single hinge fixing body (10A) so as to fix one end portion of the flexible display device (20A) A (11A) is reflected on a hinge foldable support surface (12) in a shape that can be supported in a folded state of the hinge.

When the opposite end of the flexible display device A 20A, which is fixed at one end to the fixed plate support A (11A) and closely fixed thereto, is positioned on the cover plate A (30A) without a support plan, The flexible display device A 20A can not be kept in a floating state on the cover plate A (30A) but is held in a protruding state by being released from the cover plate A (30A) Which can lead to damage problems of the battery.

In order to prevent this, the cover plate A (30A) should reflect the shape that the non-fixed end portion of the flexible display device (20A) can be perturbed while being supported, and as shown in FIG. 3 A perforating penetration portion 31 and a perturbation stopping protrusion 32 are formed.

The perforated perforation 31 is formed by removing the cross-sectional shape of the flexible display device A 20A located on the cover plate A 30A in the direction of the perturbation axis, The end portion of the A 20A maintains a flat surface and can be perturbed through without limitation.

 The perturbation latching jaw 32 is disposed at a predetermined position on the upper surface of the perforation penetration portion 31 so as to be capable of engaging the flexible display device 20A from both ends parallel to the pivot axis, And the surface on which the image of the flexible display device 20A is displayed is freely exposed through the opened portion.

The perturbation penetrating portion 31 and the perturbation stopping jaw 32 are similar in shape to the patent that reflects the hinge (Korean Patent Application No. 10-2010-0062787), but its function is different from the embodiments shown in the present invention It is different.

In the patent in which the hinge is reflected, a shape similar to the perforation penetrating portion 31 is formed such that both sides thereof are not penetrated in the direction of the perturbation axis but only one side located on the hinge side is formed so that one end of the flexible display device Can not be perturbed through the end surface of one end which is not in contact with the surface of the display screen, and thus the expandability of the screen display surface is lower than those of the embodiments of the present invention.

In the patent having the hinges reflected, the shape similar to the perturbation stopping chin 32 is different from the perturbation stopping chuck 32 of the present invention, Except that it only functions to hide the periphery of the flexible display device, which is not generated.

In the first embodiment, as shown in FIGS. 2, 4 and 5, the flexible display device A (50) having one end fixedly attached by a fixing plate 1 (50) The fixed portion of the hinge 20A is kept in a fixed state in which it can not be perturbed, and the opposite end portion located on the side of the cover plate A (30A) is maintained in a perturbed perturbed state, The increase of the L1 value according to the increase of the folding angle is effected by offsetting the end portion of the flexible display device A 20A located on the side of the cover plate A 30A with the hinge side, Damage such as tearing of the flexible display device 20A can be avoided and the electric connection state of the single hinge fixing body 10A and the flexible display device 20A can be easily maintained.

Also, when the hinge is changed from the fully folded state to the fully extended state, the decrease of the L1 value due to the reduction of the folding angle is caused by the end portion of the flexible display device A (20A) located on the side of the cover plate A It is possible to solve the problem that the flexible display device A (20A) rises from the hinge region as a result of perturbing and canceling.

In the first embodiment, since the non-fixed end portion of the flexible display device 20A is supported by the cover plate A (30A) and is perturbed through it, the flexible display device A (20A) There is a problem that friction occurs when the periphery of the non-hinged portion is operated, but on the other hand, it is advantageous that the components are simplified and the space of the single hinge fixing body 10A is secured.

Embodiment 2 of another embodiment of the present invention is an embodiment for improving a friction problem of an unfixed end portion of the flexible display device A 20A of Embodiment 1, 40 and the fixing plate 2 (51) are additionally applied.

7 is a perspective view and a front view of a cover plate and a perforated plate according to a second embodiment of the present invention, and Fig. 8 is a perspective view of a cover plate and a perforated plate according to Embodiment 2 of the present invention. FIG. 9 is a plan view and a sectional view in the unfolded state according to the second embodiment of the present invention. FIG.

As shown in FIGS. 6, 7, 8, and 9, the second embodiment includes a single hinge fixing body 10A having a hinge shape reflected on one corner, a single hinge fixing body 10A having a single hinge fixing body 10A, A flexible display device A (20A) in which one end portion is fixed and the remaining portion which is not fixed is held in a state capable of being folded and unfolded while being supported on the outer peripheral surface of the hinge, A perforated plate 40 which is tightly fixed to the opposite side of the display surface of the end image and surrounds the periphery of the flexible display device 20A and is perturbed together with the hinge structure of the single hinge fixing body 10A, A cover plate B (30B) having a perforation penetration portion (31) and a perturbation protrusion (32) for penetrating and supporting the perforated plate (40) The flexibility A fixed plate 1 (50) for pressing the periphery of the upper surface of the display device A (20A) and fixed to the single hinge fixing body 10A, a flexible display device A And a folding detection sensor 60 mounted on the single hinge fixing body 10A to sense folding and unfolding of the hinge, .

As shown in FIGS. 8 and 9, on one surface of the single hinge fixing body 10A according to the second embodiment, an end portion of the flexible display device A (20A) is wrapped A fixing plate support portion A (11A) having a recessed shape is formed.

As shown in FIG. 7, the cover plate B (30B) of the second embodiment has a central portion penetratingly removed so that the peristaltic plate 40 can be perturbed in the direction of the perturbation axis, similarly to the first embodiment The upper surface existing on the perforation penetration portion 31 is formed with a predetermined length that allows the perforation plate 40 to be engaged from both ends parallel to the pivot axis, A percussion locking step 32 is formed.

In addition, a perforated plate supporting portion 41 is formed on one surface of the perforated plate 40 to enclose and fix a non-fixed end portion of the flexible display device 20A.

In order to solve the friction problem of the first embodiment described above, in the second embodiment, as shown in FIGS. 6, 8 and 9, the flexible display device A The unfixed end of the upper plate 20A is integrally formed with the sup- port plate 40 by the fixing plate 2 (51), which is pressed against the upper surface and fixed to the sup- port plate supporting portion 41 side, do.

As described above, in Embodiment 2, since the periphery of the non-fixed end portion of the flexible display device A 20A maintains a relationship in which the periphery of the non-fixed end portion of the flexible display device A is not in direct contact with the cover plate B (30B) It is possible to solve the friction problem.

However, in the second embodiment, the height of the perforation penetration portion 31 of the cover plate B (30B) is greater than the height of the cover plate A (30) of the first embodiment due to the additional application of the peristaltic plate 40 and the fixation plate 2 The hinge folding support surface 12 of the single hinge fixing body 10A is moved toward the fixed plate support portion A 11A side of the first hinge fixing body 30A to increase the height of the perforation penetration portion 31 of the first hinge fixing body 30A, The space for securing the single hinge fixing body 10A becomes disadvantageous.

The flexible display device 20A or the flexible plate 40 is peripherally supported by the perturbation latching jaw 32 when the hinge is unfolded in the first and second embodiments and is pushed out of the hinge rotation axis, Is the elastic force of the flexible display device A (20A) at the hinge region.

However, the elastic force of the flexible display device A (20A) at the hinge portion along the unfolding progress of the hinge causes the non-fixed end portion of the flexible display device A (20A) or the perturbation driving force And when the adjacent portion of the hinge of the flexible display device 20A is peeled off from the single hinge fixing body 10A and the elastic force is not converted into the perturbing driving force, .

Therefore, in order to smoothly perturb the non-fixed end of the flexible display device A (20A) or the supporter (40) by using the elastic force when the hinge spread is progressed, So as not to be peeled from the single hinge fixing body 10A.

To this end, as shown in FIGS. 4, 5, 8 and 9, one end portion of the flexible display device 20A is formed in a two-step recessed shape formed on one surface of the single hinge fixing body 10A And is characterized in that it is wrapped around the lower end of the fixing plate supporting portion 11 and fixed to the upper end of the fixing plate supporting portion A 11A by pressing the fixing plate 1 (50) around the upper surface where the image display surface is positioned .

In the first and second embodiments, as shown in FIGS. 2 and 6, a fixing body having a single hinge at one corner is applied. As shown in FIG. 2 and FIG. 6, The method is difficult and interference may occur at the intersection of the cover plates at the folding and unfolding of the hinge even if the hinge is further applied to the other opposite corner for expanding the image display surface.
