Description

Roll double video display device {DISPLAY APPARATUS WITH A CAPABILITY OF A FOLDING AND ROLLING FLEXIBLE DISPLAY}

The present invention relates to a rollable image display device in which one end of a flexible display mean such as flexible OLED and electronic paper is freely bent and a foldable function is applied and the other end is a rollable function. More specifically, one end of the flexible display device is not affected by the opposite end to which the rolling function is applied. In-folding or out-folding function is applied, and the other side to which the rolling function is applied is the folding function. The present invention relates to a roll double image display device that is free to implement independent folding and rolling functions without being affected by the opposite side.

As the technology of image display device is advanced, image devices and communication devices using flexible display means such as e-Ink and flexible OLED panel that can bend and fold are proposed. In order to implement this, rollable methods using a roller (a winding method and a sliding method) and foldable method patents that maintain and maintain a constant curvature in the folding shaft portion have been proposed.

In the case of a patent with a rollable method, one side winding method of winding and unfolding one end portion of the flexible display device by using a winding roller is carried out, and one end portion of the flexible display device is used by using a turning roller. One-sided sliding method to perform sliding after switching, two-sided winding method to wind and unfold both ends of the flexible display device by using two winding rollers, respectively, and flexible display by using two turning rollers Two side edge sliding schemes have been proposed, in which both end portions of the device are slid after redirection.

Separate winding or turning rollers are applied to both ends of the flexible display device, so that the sliding or winding after sliding direction is the screen size corresponding to the screen size of a smartphone, which is a kind of the existing image-invariant video display device when minimized. Compared to having a large screen in the maximized state of the shape-invariant image display device has the advantage of obtaining a large screen corresponding to the tablet screen size.

However, when the winding rollers or the turning rollers on both sides are operated at the same time, the flexible display device that the components or components of the components for driving the rollers are overlapped with each other or turned at both ends and rolled inward toward each other and moved. Problems may occur in which the ends of the may interfere with each other.

And when the user grasps both ends and pulls outwards or pushes in the direction of contraction, there is a problem that the user and the control device do not know which roller will operate unless there is a special limiting device.

In addition, in the case of the patent applied to the foldable method, one end part of the same direction foldable video display device or the flexible display device in which both ends of the flexible display device are infolded or all outfolded is infolded, and the opposite one end part A composite folding image display device that is outfolded has been proposed.

The same direction folding video display device and composite folding video display device have the advantage of obtaining a large screen corresponding to the size of the existing tablet screen when the folded state is unfolded, but due to the rotation problem of the folding axis that causes the folding Along with the difficulty of maintenance, there is a disadvantage in that there is a limitation in the manner of use which must observe the folding or unfolding order of both ends.

In addition, the same direction folding video display device and composite folding video display device can not be expanded beyond the horizontal dimension of the folding rotary plate, which is a unique characteristic component of the foldable method, and the overall thickness of the folded state is proportional as the number of folding stages increases. There is also a disadvantage that it increases (thickness of existing smartphones and tablets: T, folded state thickness of one-stage folding method: 2T, folded state thickness of one-way folding video display device and composite folding video display device: 3T).

The technical problem to be achieved by the present invention is first, when the expansion and contraction of both ends of the flexible display device, even if the user does not limit the operation of one side does not cause mutual interference related to both ends of the flexible display device and the user or control It is intended to allow the device to know exactly which side of the expansion and contraction is being performed.

Second, the folded state thickness (2T) that the one-fold folding method can have the minimum folded state thickness while realizing more than the maximum spread screen size that the one-way folding video display device and the composite folding video display device can realize in the maximum unfolded state. It is intended to implement a shape-deformation video display device having the following folding thickness.

Hereinafter, exemplary 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 describing particular embodiments only and is not intended to be limiting of the invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. In addition, since reference is made to preferred embodiments, reference numerals provided in the order of description are not necessarily limited to the order.

1 is a plan view, a front view, and a plan view and a front view of a tablet device of a conventional smartphone that is invariant in shape.

As shown in FIG. 1, the conventional smartphone, which is the shape-invariant video display device 1, has good portability but has a small screen size, and the tablet, which is another shape-invariant video display device 1, is less portable and has a wider screen. Has the advantage of providing. In the case of the shape-invariant video display device 1 applying a display device that cannot be changed in shape such as an LCD panel, it is impossible to satisfy portability and a large screen at the same time by utilizing only the advantages of these two devices. Or a large screen smartphone (aka phablet phone) with a 7-inch screen is preferred.

However, due to technological development, patents have been applied to propose a flexible display mean such as an e-ink and a flexible OLED panel that can be bent, folded, and wound. Patents for rollable method (folding method and sliding method) used and foldable method for keeping and keeping a constant curvature in the folding shaft part have been proposed.

2 is a perspective view and a front view of a fully folded state of a composite folding image display device on which one side is applied to the infolding method and the other side is an outfolding method, and FIG. 3 is a perspective view of a fully unfolded state to the image display device of FIG. And front view.

In the case of the patent applied to the foldable method, a unidirectional folding image display device (not shown) in which both ends of the flexible display device are both infolded or outfolded, or as shown in FIGS. 2 and 3 A composite folding image display device 10 is proposed in which one end portion of the device is infolded and the other end portion is outfolded.

In the case of the same-direction folding image display device and the composite folding image display device 10, when the folded state is fully expanded, as shown in FIG. 3, a large screen corresponding to the size of the existing tablet screen, which is the shape-invariant image display device 1, is shown. However, due to the problem of the rotation of the folding axis 130, the folding occurs, in the same direction foldable image display device, the folding or unfolding order of both ends must be observed. Or in the case of the composite folding image display device 10 must observe the infolding and outfolding direction.

As shown in FIG. 3, when a finger (shown in dotted line) performing a touch operation is operated while changing a position (A or B or C) with the same force F, a moment (force) associated with downward rotation according to the touch manipulation position the distance from the x axis of rotation) varies.

If the position of the touch operation is applied to the position of the finger A, it is indicated by the solid line and the rotation moment is not affected by the hand holding the device, so that the downward rotation due to the touch operation does not occur.

However, if touch operation is performed at the position of finger B, the expanded additional screen 1 (12) and the extended additional screen 2 (13) are displayed on the F x L based on the out-folding folding axis despite the presence of a hand holding the device. When the downward rotation moment value corresponding to the size is applied and the touch operation is performed at the position of the finger C, the expanded additional screen 1 (12) and the expanded additional screen 2 (13) correspond to the size of F x 2L based on the outfolding folding axis. It can be seen that the 2 times increased downward rotation moment value is applied, so that the farther away the folding axis, the more difficult to maintain the plane.

In addition, the same direction folding image display device and composite folding image display device 10, as shown in Figure 2 with the disadvantage that it can not be expanded beyond the horizontal dimensions of the foldable rotating component of the foldable unique characteristic components As the increases, the overall thickness of the folded state also increases proportionally (thickness of existing smartphones and tablets: T, folded state of 1-stage folding type: thickness of 2T, one-way folding video display and composite folding video display: 3T) also has the disadvantage.

FIG. 4 is a perspective view and a front view of a fully folded state of a sliding bidirectional sliding image display device in which a turning roller is applied to both edges, and FIG. 5 is a plan view of a fully folded state of the image display device of FIG. 6 is a perspective view and a front view of a fully unfolded state of the image display apparatus of FIG. 4, and FIG. 7 is a fully folded state of a bidirectional wound image display apparatus of a cylindrical winding type in which a winding roller is opposed to both edges thereof. 8 is a plan view and a cross-sectional view of a fully folded state of the image display device of FIG. 7, and FIG. 9 is a perspective view and a front view of a fully unfolded state of the image display device of FIG. 7.

In the case of the patent that the rollable method is applied, one side winding portion of the one end portion of the flexible display device is wound and unfolded in a cylindrical shape using the winding roller 33. One side sliding image display device which performs sliding after changing the one end portion of the display device, as shown in FIGS. 4, 5, and 6, by using two turning rollers 23, both sides of the flexible display device. Bidirectional sliding image display device 20 performing sliding after changing the end portions respectively and two winding rollers 33 as shown in FIGS. 7, 8 and 9, and both end portions of the flexible display device. Bi-directionally wound image display devices 30 for winding and unfolding cylindrical shapes, respectively, have been proposed.

The bidirectional sliding image display device 20 and the bidirectional wound image display device 30 have a screen size (a horizontal dimension L) corresponding to a smartphone screen size, which is a kind of the existing shape-invariant image display device 1 in a minimized state. In the maximized state, it is possible to obtain a large screen corresponding to the tablet screen size (horizontal dimension 3L), which is another one of the shape-invariant image display apparatus 1.

However, as shown in FIGS. 4 and 7, when the user applies the roller driving force to both hands indicated by the solid line for expanding or reducing the screen, the turning roller 23 or the winding roller 33 on both sides is operated at the same time. The left sliding expansion additional screen 25 and the right sliding which move the components or the operating spaces of the components for driving the rollers overlap each other or as shown in FIG. There may be a problem that may interfere with each other when the free end portion of the extended additional screen 26 intersects.

6 and 9, when the user grasps both ends and pushes in the direction of pulling outward or contracting in the opposite direction, unless the user places a special limiting device on the bidirectional sliding image display device 20. There is a problem of uncertainty unknown to the user and the control device whether the turning roller 23 is operated to change the left sliding extension additional screen 25 or the right sliding extension additional screen 26. If the device 30 does not have a special restriction device, the user and the control device may know which winding roller 33 is operated to cause a change in the left unfolding extension screen 35 or the right sliding extension screen 36. There is a myriad of uncertainties.

However, as shown in FIGS. 6 and 9, the bidirectional sliding image display device 20 and the bidirectional wound image display device 30 are finger A, finger B, and finger C having dotted lines performing touch operations due to the absence of the folding axis. In spite of the touch operation, it can be seen that the downward rotation moment generated in the composite folding image display device 10 does not occur, thereby maintaining the plane.

In order to improve the problems of the shape-invariant image display apparatus 1 shown in FIG. 1, a composite folding image display apparatus 10, a bidirectional sliding image display apparatus 20, and a bidirectional winding image display apparatus 30, which are previously applied patents, are proposed. In spite of having the advantages of a foldable method or a rollable method individually, it has been suggested that there are still disadvantages to be improved by the drawings and the descriptions exemplified in FIGS. 2 to 9.

Accordingly, the present invention proposes an alternative for improving the disadvantage that each of the above-described methods does not solve while having the advantages of the foldable method and the rollable method, and this method applies both the rollable method and the foldable method to a single image display device. A rollable and foldable image display apparatus (hereinafter, referred to as a self-rolling rollable image display apparatus) will be described through embodiments described below.
