Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a display device in a rolled state according to an embodiment of the disclosure. Referring to fig. 1, the display device includes a fixed housing 10, a sliding housing 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 A-A plane in FIG. 1. Referring to fig. 2, the flexible display panel 40 includes a flat display portion 401, a roll display portion 402, and a binding portion 403, a first side of the flat display portion 401 is connected to one side of the 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 opposite sides of the flat display portion 401, that is, the roll display portion 402, the flat display portion 401, and the binding portion 403 are sequentially connected. The slide scroll display portion 402 and the flat display portion 401 of the flexible display panel are used to display a screen.

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

The display device further includes a flexible circuit board 50. The flexible circuit board 50 is bonded to the bonding portion 403. The binding portion 403 and the flexible circuit board 50 are both located at the rear surface of the flat display portion 401, and there is a gap with the rear surface of the flat display portion 401 through which the moving path of the support 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 201.

The moving path of the support 201 is an 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 at both sides of the moving path of the supporting member 201 means that the supporting member 201 may 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 also a gap between the binding portion 403 and the back surface of the flat display portion 401, in which the supporting member 201 is located when the display device is in the rolled state. At this time, the flat display portion 401 is located at one side of the support 201 in a direction perpendicular to the rear surface of the flat display portion 401 (i.e., the third direction c), and the flexible circuit board 50 and the binding portion 403 are located at the other side of the support 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 201, and the flexible circuit board 50 and the binding portion 403 are located below the support 201. In this way, the supporting member 201 does not interfere with the flat display portion 401 and the flexible circuit board 50 while 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 slide housing 20 slides a distance in the first direction a with respect to the fixed housing 10, a portion of the slide-roller display portion 402 slides out of the slide 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 fixed case 10.

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

As shown in fig. 4, when the display device is in the unfolded state, the display surface of the roll display portion 402 supported by the support 201 is located on the same plane as the display surface of the flat display portion 401.

In the embodiment of the present disclosure, since the flat display part and the flexible circuit board are located at both sides of the moving path of the support, the support does not interfere with the flexible circuit board and the binding part in the process of sliding along with the sliding housing, and can move between the flexible circuit board and the flat display part. In the case where the size of the flat display portion in the first direction is fixed, the stroke of the slide housing increases as compared with the case where the moving path of the support cannot pass between the flexible circuit board and the flat display portion in the related art, so that the range of the screen size in which the roll screen can be adjusted increases.

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 housing 10, and 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 being opposite to the second surface. I.e., the bracket 60 is located at the interface of the flat display portion 401 and the binding portion 403, and is located between the flat display portion 401 and the binding portion 403.

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

Fig. 5 is an exploded view of a stationary housing, a sliding housing and a bracket according to an embodiment of the present disclosure. Referring to fig. 5, the stationary housing 10 has a sliding groove 101, and the support 201 is slidably located in the sliding groove 101. The sliding groove 101 allows the support 201 to slide.

Referring again to fig. 5, the fixed housing 10 further has a mounting portion 102, the sliding grooves 101 and the mounting portion 102 are arranged along the first direction a, and the bracket 60 is located at the mounting portion 102, so that stability of the bracket 60 is ensured.

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.

The flat display portion 401 is covered on the sliding groove 101, and the support 201 slides in the sliding groove 101, that is, the support 201 slides in the cavity formed by the flat display portion 401 and the sliding groove 101. The support member 201 also supports the flat display portion 401 when the support member 201 is in the sliding groove 101, and the flat display portion 401 is not supported when the support member 201 slides out of the sliding groove 101. In the embodiment of the present disclosure, the supporting members 201 are arranged as a plurality of first supporting bars 211 spaced apart so that the sliding grooves 101 in which the first supporting bars 211 slide may also be arranged as a plurality of sub-sliding grooves 111, the plurality of first supporting bars 211 serve to support the roll display part 402 after the first supporting bars 211 slide out of the sub-sliding grooves 111, and the supporting protrusions 112 between adjacent two sub-sliding grooves 111 serve to support the flat display part 401, thereby ensuring that both the roll display part 402 and the flat display part 401 are supported.

Referring again to fig. 5, the bracket 60 has a receiving chamber 61 thereon, and the receiving chamber 61 communicates with the sliding groove 101.

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

Fig. 6 is a schematic structural view of a bracket according to an embodiment of the present disclosure. Referring to fig. 6, the bracket 60 includes: the first support plate 601, the second support plate 602 and the transition plate 603 each extend in the second direction b. In the third direction c, the second support plate 602 is opposite to and spaced apart from the first support plate 601, one side of the transition plate 603 is connected to one side of the first support plate 601, and the other side of the transition plate 603 is connected to one side of the second support plate 602. The surface of the first support plate 601 opposite to the second support plate 602 is a first surface, the surface of the second support plate 602 opposite to the first support plate 601 is a second surface, and the first support plate 601, the second support plate 602 and the transition plate 603 define the accommodating chamber 61.
