Fixed casing and slip casing sliding connection, rolling structure are located the slip casing. The flexible display panel includes a flat display portion, a roll display portion, and a binding portion. A first side of the flat display portion is connected to one side of the slider display portion, and a second side of the flat display portion opposite to the first side is connected to one side of the binding portion. The flat display part is connected with the fixed shell, the middle part of the sliding roll display part is connected with the supporting piece of the sliding shell in a sliding mode, and the other side edge of the sliding roll display part is fixedly connected with the rolling structure. The binding part is positioned on the back surface of the flat display part and attached to the back surface, and the FPC bound with the binding part is also positioned on the back surface of the flat display part.

When the sliding scroll screen is unfolded, the sliding housing moves away from the fixed housing, so that a part of the supporting member is located outside the fixed housing to support the sliding scroll display part. When the sliding scroll screen is folded, the sliding shell moves towards the fixed shell, so that the supporting piece slides towards the FPC. Because the supporting member, the binding portion and the FPC are all positioned on the back surface of the flat display portion and attached to the back surface, the supporting member is also attached to the back surface of the flat display portion in the moving process, and if the moving path of the supporting member is too long, interference can occur between the supporting member and the binding portion and between the supporting member and the FPC. Therefore, in the case where the sizes of the flexible display panel and the support member are fixed, the moving path of the support member is short, resulting in a small range of screen sizes that can be adjusted by the roll-up screen.

Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a display device in a rolling state according to an embodiment of the present disclosure. Referring to fig. 1, the display device includes a fixed case 10, a sliding case 20, and a flexible display panel 40. The fixed housing 10 and the sliding housing 20 provide support for the flexible display panel 40, and the sliding housing 20 is slidable with respect to the fixed housing 10.

Fig. 2 is a cross-sectional view taken along the plane a-a in fig. 1. Referring to fig. 2, the flexible display panel 40 includes a flat display portion 401, a sliding roll display portion 402, and a binding portion 403, wherein a first side of the flat display portion 401 is connected to one side of the sliding roll display portion 402, a second side of the flat display portion 401 is connected to the binding portion 403, and the first side and the second side are two opposite sides of the flat display portion 401, that is, the sliding roll display portion 402, the flat display portion 401, and the binding portion 403 are sequentially connected. The roll display portion 402 and the flat display portion 401 of the flexible display panel are used to display a picture.

In which the flat display portion 401 is connected to the stationary case 10. The display device further comprises a rolling structure 30, and the rolling structure 30 is located in the sliding housing 20. The winding structure 30 is used for winding the sliding roll display part 402 inside the sliding housing 20. The other side of the sliding roll display part 402 is fixedly connected with the rolling structure 30. The slide case 20 has a support member 201, and the middle portion of the roll display portion 402 is slidably coupled to the support member 201.

The display device further includes a flexible circuit board 50. The flexible circuit board 50 is bound with the binding portion 403. The binding portion 403 and the flexible circuit board 50 are located on the back surface of the flat display portion 401 with a gap from the back surface of the flat display portion 401 through which the moving path of the support member 201 passes. That is, the flat display portion 401 and the flexible circuit board 50 are located at both sides of the moving path of the support member 201.

Wherein, the moving path of the support 201 is the area through which the support 201 passes when moving. The fact that the flat display portion 401 and the flexible circuit board 50 are located on two sides of the moving path of the supporting member 201 means that the supporting member 201 can pass between the flat display portion 401 and the flexible circuit board 50 during the moving process, but does not interfere with the flat display portion 401 and the flexible circuit board 50.

In the embodiment of the present disclosure, there is a gap between the flexible circuit board 50 and the back surface of the flat display portion 401, and there is a gap between the binding portion 403 and the back surface of the flat display portion 401, in which the support member 201 is located when the display device is in the rolled state. At this time, in a direction perpendicular to the rear surface of the flat display portion 401 (i.e., the third direction c), the flat display portion 401 is located at one side of the support member 201, and the flexible circuit board 50 and the binding portion 403 are located at the other side of the support member 201. For example, in fig. 2, when the display device is in a rolled state, the flat display portion 401 is located above the support member 201, and the flexible circuit board 50 and the binding portion 403 are located below the support member 201. Thus, the support member 201 does not interfere with the flat display portion 401 and the flexible circuit board 50 when passing between the flat display portion 401 and the flexible circuit board 50.

Fig. 3 is a schematic structural diagram of a display device in an unfolded state according to an embodiment of the present disclosure. Referring to fig. 3, when the sliding housing 20 slides a distance in the first direction a with respect to the stationary housing 10, a portion of the sliding scroll display part 402 slides out of the sliding housing 20, so that the screen size of the display device increases. The first direction a is a relative movement direction of the slide case 20 and the stationary case 10.

In the embodiment of the present disclosure, since the sliding roll display portion 402 needs to be rolled, the sliding roll display portion 402 needs to have a certain flexibility, and in order to ensure that the sliding roll display portion 402 can display normally and avoid the sliding roll display portion 402 from collapsing, a support structure needs to be arranged to support the sliding roll display portion 402. Fig. 4 is a sectional view taken along the plane B-B in fig. 3. Referring to fig. 4, the sliding housing 20 has a support member 201, and the support member 201 is used for supporting the rolled-out display portion 402 to ensure the flatness of the surface of the rolled-out display portion 402.

As shown in fig. 4, when the display device is in the unrolled state, the display surface of the roll display section 402 supported by the support member 201 is positioned on the same plane as the display surface of the flat display section 401.

In the embodiment of the present disclosure, since the flat display portion and the flexible circuit board are located at both sides of the moving path of the support member, the support member does not interfere with the flexible circuit board and the binding portion in the process of sliding along with the sliding housing, and can move between the flexible circuit board and the flat display portion. In the case where the size of the flat display portion in the first direction is fixed, the stroke of the slide case is increased as compared with the case where the moving path of the support member cannot pass between the flexible circuit board and the flat display portion in the related art, thereby enabling the range of screen sizes that the slide-rolling screen can adjust to be increased.

Referring again to fig. 2 and 4, in the embodiment of the present disclosure, in order to ensure that there is a gap between the binding portion 403 and the flat display portion 401, the display device further includes: a bracket 60. The bracket 60 is mounted on the fixed case 10, a portion of the flat display portion 401 is connected to a first surface of the bracket 60, and the binding portion 403 and the flexible circuit board 50 are located on a second surface of the bracket 60, the first surface and the second surface being opposite to each other. That is, the supporter 60 is located at the boundary between the flat visual display portion 401 and the binding portion 403 and between the flat visual display portion 401 and the binding portion 403.

In the embodiment of the present disclosure, the bracket 60 is disposed in the stationary housing 10 to fix the flexible circuit board 50 and the binding portion 403, and to ensure stability of the relative positions of the flexible circuit board 50 and the binding portion 403.

The second direction b is perpendicular to the first direction a, and the second direction b is parallel to the first surface of the flat display portion 401, that is, the second direction b, the first direction a, and the third direction c are perpendicular to each other two by two.

The flat display portion 401 covers the sliding groove 101, and the supporting member 201 slides in the sliding groove 101, that is, the supporting member 201 slides in a cavity formed by the flat display portion 401 and the sliding groove 101. When the supporting member 201 is in the sliding groove 101, the supporting member 201 also supports the flat display portion 401, and when the supporting member 201 slides out of the sliding groove 101, the flat display portion 401 is not supported. In the embodiment of the present disclosure, the supporting members 201 are disposed as a plurality of first supporting bars 211 at intervals, so that the sliding grooves 101 for the first supporting bars 211 to slide may also be disposed as a plurality of sub-sliding grooves 111, when the first supporting bars 211 slide out of the sub-sliding grooves 111, the plurality of first supporting bars 211 are used to support the scroll display part 402, and the supporting protrusions 112 between two adjacent sub-sliding grooves 111 are used to support the flat display part 401, thereby ensuring that the scroll display part 402 and the flat display part 401 are supported.

In the embodiment of the present disclosure, the support member 201 slides in the sliding groove 101, and the accommodating chamber 61 communicating with the sliding groove 101 is disposed in the bracket 60, so that a portion of the support member 201 can slide into the accommodating chamber 61, further increasing the sliding distance of the support member 201, thereby increasing the range of screen sizes that can be adjusted by the display device. Meanwhile, under the condition that the sliding distance of the supporting member 201 is not changed, the size of the supporting member 201 in the first direction a can be increased, the supporting area of the supporting member 201 is increased, and the supporting performance of the supporting member 201 is increased.

Fig. 6 is a schematic structural diagram of a bracket according to an embodiment of the present disclosure. Referring to fig. 6, the bracket 60 includes: a first support plate 601, a second support plate 602, and a transition plate 603, and all extend in the second direction b.
