On one hand, the guide part supports the support part, so that direct contact, friction and extrusion among the curled screen bodies are avoided in the process of curling and unfolding the screen bodies, the phenomenon of damage of the screen bodies is reduced, and the screen bodies of the display device are protected; on the other hand, the second reel can timely wind and unwind the supporting component, and the supporting component does not need to be unwound along with the screen body when the screen body is unwound, so that the appearance of the screen body in an unwound state is not affected. Therefore, the embodiment of the invention realizes the protection of the screen body on the premise of not influencing the appearance of the screen body.
Further, the area of the cross-section of the second roller is smaller than the area of the cross-section of the first roller. Compared with a screen body, the supporting part is not easy to damage, and therefore the cross section area of the second reel can be smaller, so that the size of the display device is reduced, and the display device is miniaturized. Correspondingly, the cross sectional area of the first scroll is large, so that the curvature radius of each point on the screen body in a curled state can be increased, the damage caused by the overlarge curled degree of the screen body can be avoided, and the screen body can be protected.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background, the screen body of the conventional display device is easily damaged during the rolling process. The inventor researches and finds that the reason of the problem is as follows:
fig. 1 is a schematic structural diagram of a conventional display device in a curling process. Referring to fig. 1, the screen body is rolled up by winding the screen body 110 around a reel 120 (the direction of the arrow in fig. 1 indicates the rolling direction of the screen body 110), so as to enrich the product form of the display device and further expand the application range of the display device. However, since the screen body 110 of the conventional display device has a large hardness, the screen body 110 may warp during the curling process. The screen body warping causes the screen body 110 to be loosely wound on the reel 120, the screen body 110 is easy to loosen, and the adjacent two layers of screen bodies 110 generate friction. In addition, in the use process of the display device, particles 130 are easily dropped on the screen body 110, and the particles 130 scratch or scratch the screen body 110 due to the friction between the screen bodies 110, so that the screen body 110 has poor display such as dark spots.
In view of the above, embodiments of the present invention provide a display device, which may be, for example, a mobile phone, a television, an electronic book, a wearable device, and the like. Fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present invention, fig. 3 is a schematic structural diagram of a cross section taken along a-a 'in fig. 2, and fig. 4 is a schematic structural diagram of a cross section taken along B-B' in fig. 2. Referring to fig. 2 to 4, the display device includes: a screen body 210, a first reel 220, a support member 230, and a guide member 240.
Wherein, the screen body 210 includes a first end portion 211, and the first end portion 211 of the screen body 210 is fixed on the surface of the first reel 220; so that the first reel 220 can pull the screen body 210 to wind on the surface of the first reel 220. Illustratively, in the unfolded state of the panel 211, only the first end 211 is fixedly attached to a surface of the first spool 220; in the rolled state of the screen 211, the screen 211 is rolled on the first roller 220 for at least two turns.
The supporting member 230 includes a first end 231 and a side portion, wherein the first end 231 of the supporting member 230 corresponds to the first end 211 of the screen 210; the side of the support member 230 corresponds to the guide rail 241 of the guide member 240. Referring to fig. 3 and 4, the first end 231 of the supporting member 230 is wrapped on the surface of the first reel 220 by the first end 211 of the screen body 210; so that the first reel 220 pulls the support member 230 while pulling the screen body 210, and the support member 230 and the screen body 210 are wound around the first reel 220 to form a rolled stack. Thus, the support member 230 is supported inside the panel 211 in the rolled state of the panel 211.
Referring to fig. 2 and 4, the guide member 240 is located at one end of the first reel 220, the guide member 240 includes a guide rail 241, and the side of the support member 230 is located in the guide rail 241. The portion of the support member 230 shown in fig. 4 within the guide track 241 is just the side of the support member 230. Therefore, the side portion of the support member 230 can slide in the guide rail 241, and the guide rail 241 supports the side portion of the support member 230, i.e., the support member 230. And the guide member 240 is located at one end of the first winding shaft 220, which does not block the winding of the screen body 210, and therefore, the arrangement of the guide member 240 does not affect the normal operation of the first winding shaft 220.
With continued reference to fig. 3, a side of the portion of the screen 211 wound on the first reel 220 near the axial center of the first reel 220 is defined as an inner side of the screen 211; on the contrary, the side away from the axial center of the first reel 220 is the outer side of the screen 211; the side of the portion of the support member 230 wound around the first reel 220 near the axial center of the first reel 220 is defined as the inner side of the support member 230. Under the support of the guide rail 241, there is a gap between the support member 230 and the screen 211 located inside the support member, so that there is a gap d between two adjacent layers of screens 210, that is, there is a gap d between the inner surface of the screen 211 located outside the first reel 220 and the outer surface of the screen 211 located inside the first reel 220. And the interval d should be greater than the thickness of the support member 230 so as to avoid direct contact, friction and compression between the adjacent two panels 210.
Illustratively, the direction of the double-headed arrow in fig. 3 indicates that the screen body 210 can be both wound on the first reel 220 and unwound from the first reel 220. The display device is curled by rotating the first reel 220 clockwise (rightward arrow direction), pulling the screen body 210 to wind on the first reel 220, sliding the supporting member 230 in the guiding track 241 along the rotating direction of the first reel 220, and winding the following screen body 210 on the first reel 220, wherein due to the supporting function of the supporting member 230, a gap d exists between two adjacent layers of screen bodies 210, thereby avoiding direct contact, friction and extrusion between two adjacent layers of screen bodies 210 in the curling process and in the curling state of the screen bodies 210. The display device is unwound by rotating the first winding shaft 220 counterclockwise (in the direction of the left arrow), and the screen body 210 is unwound from the first winding shaft 220, while the support member 230 slides in the guide rail 241 in the rotating direction of the first winding shaft 220, following the screen body 210 being unwound from the first winding shaft 220. Similarly, due to the supporting function of the supporting component 230, a gap d exists between two adjacent layers of the screen bodies 210; direct contact, friction and extrusion between two adjacent layers of the screen body 210 during the unfolding process of the screen body 210 are avoided.
In summary, the embodiments of the present invention provide a simple implementation scheme to protect the screen of the display device. Specifically, the embodiment of the invention provides the guide part 240 at one end of the first reel 220, and the guide rail 241 of the guide part 240 supports the support part 230, so that a gap d exists between two adjacent layers of the panels 210 during the winding and unwinding of the panels 210 and in the rolled state. Therefore, the embodiment of the invention avoids direct contact, friction and extrusion among the curled screen bodies 210, thereby reducing the phenomenon that the screen bodies 210 are damaged, realizing the protection of the screen bodies 210 of the display device and improving the display quality of the display device.
With continued reference to fig. 2-4, in one embodiment of the present invention, optionally, the number of guide members 240 is two; a guide member 240 is located at one end of the first bobbin 220; another guide member 240 is located at the other end of the first bobbin 220. In this way, the guide member 240 may provide support to the support member 230 from both sides of the support member 230. If only one guide member 240 is provided, the guide member 240 can only support one end of the support member 230, and the other end of the support member 230 is not supported, so that the support member 230 is easily inclined during the winding and unwinding processes. In the embodiment, the guide members 240 are disposed at both ends of the first winding shaft 220, which is beneficial to preventing the support member 230 from being inclined in the process of curling and unwinding, and improving the support effect of the guide members 240 on the support member 230.
Fig. 5 is a schematic view of another cross-sectional structure taken along a-a 'of fig. 2, and fig. 6 is a schematic view of another cross-sectional structure taken along B-B' of fig. 2. Referring to fig. 5 and 6, in one embodiment of the present invention, optionally, the support member 230 further includes a second end 232, the second end 232 of the support member 230 being opposite the first end 231 of the support member 230. The second end 232 of the supporting member 230 is opposite to the first end 231 thereof, which means that the second end 232 and the first end 231 of the supporting member 230 are respectively located at two ends of the supporting member 230 in the winding direction, i.e. the first end 231 and the second end 232 of the supporting member 230 are connected by a side portion.
The display device further includes a second reel 250, the second end 232 of the support member 230 is fixed to a surface of the second reel 250, and the support member 230 is wound around the second reel 250 to form a roll stack.
Illustratively, the display device is rolled up by rotating the first reel 220 and the second reel 250 clockwise, the screen body 210 is wound on the first reel 220, and the supporting member 230 is disengaged from the second reel 250, slides in the guiding track 241 along the rotating direction of the first reel 220, and follows the screen body 210 to be wound on the first reel 220, and due to the supporting function of the supporting member 230, there is a gap d between two adjacent layers of screen bodies 210, so that direct contact, friction and compression between two adjacent layers of screen bodies 210 are avoided during the rolling up process and in the rolled up state of the screen body 210. The display device is unfolded in such a way that the first reel 220 and the second reel 250 rotate counterclockwise, the screen body 210 is separated from the first reel 220 and unfolded, meanwhile, the supporting member 230 slides in the guiding track 241 along the rotating direction of the first reel 220 and is wound on the second reel 250, and due to the supporting function of the supporting member 230, a gap d exists between two adjacent layers of screen bodies 210; direct contact, friction and extrusion between two adjacent layers of the screen body 210 during the unfolding process of the screen body 210 are avoided.
As can be seen from the above analysis, the supporting member 230, the guiding member 240 and the second winding shaft 250 form a set of winding guiding system, which is matched with the first winding shaft 220, on one hand, the guiding member 240 supports the supporting member 230, so that during the winding and unwinding of the screen body 210, direct contact, friction and extrusion between the winding screen body 210 are avoided, thereby reducing the damage of the screen body 210 and protecting the screen body 210 of the display device; on the other hand, the second reel 250 can timely wind and unwind the support member 230, and the support member 230 does not need to be unwound along with the screen body 210 when the screen body 210 is unwound, thereby not affecting the appearance of the screen body 210 in the unwound state. Therefore, the embodiment of the invention realizes the protection of the screen body on the premise of not influencing the appearance of the screen body 210.
With continued reference to fig. 5 and 6, in one embodiment of the present invention, the cross-sectional area of the second roller 250 is optionally smaller than the cross-sectional area of the first roller 220. Here, the cross section refers to a sectional shape in a direction perpendicular to the axial direction of the first reel 220 (or the second reel 250), and the larger the area of the cross section, the larger the size of the first reel 220 (or the second reel 250) is. The supporting member 230 is less likely to be damaged than the screen body 210, and thus, the cross-sectional area of the second reel 250 can be set to be smaller, thereby contributing to a reduction in size of the display device and to miniaturization of the display device. Correspondingly, the cross-sectional area of the first winding shaft 220 is larger, which is beneficial to increasing the curvature radius of each point on the screen body 210 in a curling state, thereby being beneficial to avoiding damage caused by too large curling degree of the screen body 210 and being beneficial to protecting the screen body 210.
Fig. 7 is a schematic structural diagram of another display device according to an embodiment of the disclosure. Referring to fig. 7, in one embodiment of the present invention, optionally, in the maximum deployed position of the screen body 210, a portion of the support member 230 wound on the second reel 250 is in contact with the screen body 210. Taking fig. 7 as an example, in the maximum unfolded position of the screen body 210, the top of the supporting part 230 wound on the second reel 250 is in contact with the screen body 210, so as to provide support for the screen body 210.
Fig. 8 is a schematic structural diagram of another display device according to an embodiment of the present invention, fig. 9 is a schematic structural diagram of fig. 8 in a rolled state, and fig. 10 is a schematic structural diagram of a positional relationship among a first reel, a second reel, a guide member, a support member, and a housing corresponding to fig. 9. Referring to fig. 8-10, in one embodiment of the present invention, optionally, screen 210 further includes a side 212 opposite first end 211. The side 212 of the panel 210 is opposite to the first end 211, that is, the side 212 and the first end 211 of the panel 210 are respectively located at two ends of the panel 210, that is, the first end 211 and the side 212 are not in contact. For example, the first end 211 and the side 212 of the screen 210 are the top end and the bottom end of the screen 210, respectively; or the first end 211 and the side of the screen body 210 are the left end and the right end of the screen body 210, respectively.
The display device further comprises a housing 260, the housing 260 comprising a first housing part 261 and a second housing part 262. Wherein, the first housing part 261 includes a hollow cavity 2611, the hollow cavity 2611 is used for accommodating the first and second reels 220 and 250; the hollow cavity 2611 may include, for example, two spaces, one of which accommodates the first winding shaft 220 and the other of which accommodates the second winding shaft 250, and which are communicated with each other, so that the support member 230 can move between the first winding shaft 220 and the second winding shaft 250, that is, the support member 230 can be wound on the second winding shaft 250 while being unwound from the first winding shaft 220, and can also be wound on the first winding shaft 220 while being unwound from the second winding shaft 250. The first housing part 261 is provided to accommodate and protect the first scroll 220 and the second scroll 250, and the second housing part 262 is provided to enable the second housing part 262 to pull the panel 210 to be unfolded, and when the panel 210 is rolled, the second housing part 262 moves together with the panel 210 in the direction of the first scroll 220.
On the basis of the above embodiments, the display device may further include a driving component, and the driving component may be disposed in a plurality of ways, and several ways of disposing the driving component are described below.
Referring to fig. 8-10, optionally, a driving member (not shown) drives the first reel 220 and the second reel 250 to rotate synchronously in the same direction.
