DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in more details hereinafter with reference to the accompanying drawings.

[0064] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is an effect schematic diagram of the flexible display panel folding and unfolding in the display device provided by the embodiment of the present application, Figure 2is an exploded schematic view of a partial structure of a display device provided by an embodiment of the present application, Figure 3 is a back view schematic diagram of a partial structure of a display device provided by an embodiment of the present application. The display device can be a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, or any product or component having a display and a roll function. The display device can include a first housing 100, at least one second housing 200, a flexible display panel 300, a recovery plate 400, and an elastic element 500.

[0065] The second housing 200 in the display device can be in sliding connection with the first housing 100. The second housing 200 can include a mounting shell 201 and a support assembly 202 in sliding connection with the mounting shell 201. For example, the sliding direction of the support assembly 202 relative to the mounting shell 201 is parallel to the sliding direction of the mounting shell 201 relative to the first housing 100.

[0066] The flexible display panel 300 in the display device can include a planar display portion 301, a rolled display portion 302, and a non-display portion 303. The planar display portion 301 in the flexible display panel 300 can be fixed on the first housing 100. The rolled display portion 302 in the flexible display panel 300 can include a first portion 3021 arranged parallel to the planar display portion 301 and a second portion 3022 between the first portion 3021 and the planar display portion 301, and the second portion 3022 can be wound on a side of the mounting shell 201 away from the first housing 100. The non-display portion 303 in the flexible display panel 300 can be located on a side of the first portion 3021 away from the second portion 3022. The flexible display panel 300 generally has a display surface and a non-display surface arranged oppositely. For the convenience of subsequent description, the front surface of the flexible display panel is the surface on which the display surface is located, and the back surface of the flexible display panel is the surface on which the non-display surface is located.

[0067] The recovery plate 400 in the display device can be in fixed connection with the back surface of the non-display portion 303 in the flexible display panel 300, and the recovery plate 400 can be connected with the support assembly 202.

[0068] The elastic element 500 in the display device can be located between the mounting shell 201 and the support assembly 202, and the two ends of the elastic element 500 can be in contact with the mounting shell 201 and the support assembly 202, respectively.

[0069] During the unfolding process of the display device, the recovery plate 400 can drive the support assembly 202 to move towards the mounting shell 201 to apply pressure to the elastic element 500 through the support assembly 202.

[0070] For example, when the second housing 200 in the display device slides in a direction away from the first housing 100, the second housing 200 can drive the rolled display portion 302 in the flexible display panel 300 to slide out of the second housing 200, and make most of the display surfaces of the planar display portion 301 and the rolled display portion 302 in the flexible display panel 300 lie in the same plane (so that the size of the area of the flexible display panel used for displaying a picture is increased), and be used for displaying a picture. When the second housing 200 in the display device slides in a direction close to the first housing 100, the second housing 200 can drive the rolled display portion 302 in the flexible display panel 300 to slide into the second housing 200, so that the size of the area of the flexible display panel used for displaying a picture is decreased, thereby facilitating carrying.

[0071] In the present application, since the rolled display portion 302 in the flexible display panel 300 needs to be rolled, and the flexible display panel 300 has a certain flexibility. Therefore, by fixing and connecting the recovery plate 400 with the back of the non-display portion 303 in the flexible display panel 300, and connecting the recovery plate 400 with the support assembly 202 in the second housing 200. In this way, during the unfolding process of the display device, the rolled display portion 302 in the flexible display panel 300 slides out while driving the recovery plate 400 to move through the non-display portion 303; and the recovery plate 400 can drive the support assembly 202 to move in a direction close to the mounting housing 201, so as to apply pressure to the elastic element 500 through the support assembly 202; the elastic element 500 can apply a counterforce to the support assembly 202 and the recovery plate 400 after being subjected to the pressure, and then apply a force to the non-display portion 303 in the flexible display panel 300 through the recovery plate 400, which is opposite to the sliding direction of the non-display portion 303, so as to tension the flexible display panel 300 in the X-axis direction, thereby reducing the screen crease arching amount and the non-display portion 303 arching amount in the X-axis direction during the rolling process of the flexible display panel 300. That is, the probability of the overall area of the flexible display panel 300 appearing uneven is effectively reduced, so that the overall flatness of the flexible display panel 300 is better, thereby making the display effect of the display device better.

[0072] It should be noted that the present application is illustratively described by taking the first housing as the fixed housing in the rolling display device, and the second housing as the movable housing in the rolling display device.

[0073] In summary, the embodiment of the present application provides a display device, which can include a first housing, a second housing, a flexible display panel, a recycling plate and an elastic element. Since the rolled display part in the flexible display panel needs to be unrolled, and the flexible display panel has a certain flexibility. Therefore, by fixing and connecting the recycling plate with the back of the non-display part in the flexible display panel, and connecting the recycling plate with the support assembly in the second housing. In this way, during the unfolding process of the display device, the rolled display part in the flexible display panel slides out while driving the recycling plate to move through the non-display part; and the recycling plate can drive the support assembly to move towards the direction close to the installation housing, so as to apply pressure to the elastic element through the support assembly; the elastic element can apply a counter force to the support assembly and the recycling plate after being subjected to the pressure, and then apply a force to the non-display part in the flexible display panel through the recycling plate, which is opposite to the sliding direction of the non-display part, so as to tension the flexible display panel in the X-axis direction, thereby reducing the screen crease arch amount and the non-display part arch amount in the X-axis direction during the unrolling process of the flexible display panel. That is, the probability of uneven phenomenon of the overall area of the flexible display panel is effectively reduced, so that the overall flatness of the flexible display panel is better, and thus the display effect of the display device is better.

[0074] Optionally, the number of the second housing 200 in the display device can be one, and after the flexible display panel 300 is unfolded, the second housing 200 can be located on any one side of the two sides opposite to the first housing 100. As shown in Figure 1 , the second housing 200 is located on the left side of the first housing 100 and is in sliding connection with the first housing 100. Please refer to Figure 4 , Figure 4 is another effect diagram of the unfolding and folding of the flexible display panel in the display device provided by the embodiment of the present application. The number of the second housing 200 in the display device can also be two, and after the flexible display panel 300 is unfolded, the two second housings 200 can be located on the two sides opposite to the first housing 100, and the two second housings 200 can be in sliding connection with the first housing 100. It should be noted that, for the convenience of description, the following embodiments are illustratively described by taking one second housing and the first housing in sliding connection as an example.

[0075] In the embodiment of the present application, as Figure 2As shown, the side of the mounting shell 201 in the second shell 200 facing away from the first shell 100 can be in a circular arc shape. In this case, by setting the side of the mounting shell 201 in the second shell 200 facing away from the first shell 100 to be in a circular arc shape, the second part 3022 in the curled display part 302 is able to smoothly transition through the side of the mounting shell 201 facing away from the first shell 100 after being wound on the side of the mounting shell 201 facing away from the first shell 100. The curled display part 302 in the flexible display panel 300 is able to smoothly transition through the side of the mounting shell 201 facing away from the first shell 100, so that the curled display part 302 is able to stably slide connect with the side of the mounting shell 201 facing away from the first shell 100. In the actual processing process, the curled display part in the flexible display panel 300 can be connected smoothly with the side of the mounting shell 201 facing away from the first shell 100 by reducing the roughness of the side of the mounting shell 201 facing away from the first shell 100.

[0076] Optionally, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 5 is another part structure schematic diagram of a display device provided by the embodiment of the present application, Figure 6 is a structure schematic diagram of a recycling plate provided by the embodiment of the present application, Figure 7 is a connection schematic diagram of a recycling plate and a support assembly provided by the embodiment of the present application, Figure 8 is a schematic diagram of a display device in a retracted state provided by the embodiment of the present application, Figure 9This is a schematic diagram of a display device in an unfolded state according to an embodiment of this application. The support component 202 in the display device may have a first sliding groove A1, the extension direction of which may be parallel to the sliding direction of the second housing 200 relative to the first housing 100 (i.e., the direction of the X-axis in the figure). The side of the retrieval plate 400 in the display device facing away from the non-display portion 303 may have a first slider 401, and at least a portion of the first slider 401 may be located within the first sliding groove A1 in the support component 202. During the unfolding process of the display device, the first slider 401 slides within the first sliding groove A1 until it abuts against the end of the first sliding groove A1 near the mounting housing 201, thereby moving the support component 202 towards the mounting housing 201. For example, by providing the first slider 401 on the side of the retrieval plate 400 facing away from the non-display portion 303 in the flexible display panel 300, the first slider 401 can slide in cooperation with the first sliding groove A1 provided in the support component 202. Thus, during the unfolding process of the display device, firstly, the non-display portion 303 of the flexible display panel 300 drives the first slider 401 on the retraction plate 400 to slide within the first groove A1 until the first slider 401 abuts against the end of the first groove A1 near the mounting housing 201. During this sliding process, the first slider 401 drives the support assembly 202 to move closer to the mounting housing 201. Then, as the support assembly 202 moves closer to the mounting housing 201, it applies pressure to the elastic element 500 located between the mounting housing 201 and the support assembly 202. Afterward, the elastic element 500 deforms under pressure and applies a reaction force to the support assembly 202 and the retraction plate 400, thereby applying tension to the non-display portion 303 of the flexible display panel 300 through the retraction plate 400, thus tensioning the entire flexible display panel 300. For an example, please refer to [link / reference]. Figure 10 and Figure 11 , Figure 10 This application provides an embodiment of a display device in an unfolded state. Figure 9 Cross-sectional view at point A-A' Figure 11 This application provides an embodiment of a display device in an unfolded state. Figure 9 The cross-sectional view at point B-B' is shown. The elastic element 500 can be a spring or a sheet, etc. During the retraction of the display device, the elastic element 500 can gradually return to its original state. For example, after the display device is in the retracted state, the elastic element 500 is not subjected to pressure, that is, no elastic deformation occurs.

[0077] In the embodiments of this application, such as Figure 6 , Figure 7 and Figure 8As shown, the support assembly 202 in the display device can also have a limiting groove A2 in communication with the first sliding groove A1, which can be located on the side of the first sliding groove A1 away from the recycling plate 400. The side of the recycling plate 400 away from the non-display part 303 in the flexible display panel 300 can also have a limiting protrusion 402 fixedly connected with the first sliding block 401, at least part of the limiting protrusion 402 can be located in the limiting groove A2 in the support assembly 202. In this case, by setting the limiting groove A2 in communication with the first sliding groove A1 in the support assembly 202, the limiting protrusion 402 is set on the first sliding block 401. In this way, during the sliding of the first sliding block 401 in the first sliding groove A1, the cooperation of the limiting groove A2 and the limiting protrusion 402 can prevent the first sliding block 401 from being separated from the first sliding groove A1, and ensure the stable sliding of the first sliding block 401 in the first sliding groove A1. In addition, the limiting groove A2 can play a good limiting role on the limiting protrusion 402, even if the flexible display panel 300 has a tendency to warp at the tail end during the rolling process, the cooperation of the limiting groove A2 and the limiting protrusion 402 can play a fixing role on the flexible display panel 300. For example, the limiting groove A2 in the support assembly 202 can have a first groove body a1 in communication with the first sliding groove A1, and two second groove bodies a2 distributed on both sides of the first groove body a1. The number of limiting protrusions 402 fixedly connected with the first sliding block 401 can be two, part of the first sliding block 401 passes through the first sliding groove A1 and is located in the first groove body a1, and the two limiting protrusions 402 fixedly connected with the first sliding block 401 can be located in the two second groove bodies a2, respectively. In this case, by setting the limiting groove A2 to contain the first groove body a1 in communication with the first sliding groove A1, and the two second groove bodies a2 distributed on both sides of the first groove body a1, and the two limiting protrusions 402 located in the two second groove bodies a2, respectively, the limiting role of the limiting groove A2 on the limiting protrusion 402 is further ensured.

[0078] Optionally, please refer to Figure 8 and Figure 12 , Figure 12is another partial structure explosion schematic diagram of a display device provided in the embodiment of the present application. The support assembly 202 in the display device can include a support body 202a in sliding connection with the recycling plate 400, and a guide 202b in fixed connection with at least one side of the support body 202a. The support body 202a can have a first sliding slot A1, and the guide 202b can have a connecting through hole b1. The second housing 200 in the display device can further include a guide column 203, one end of the guide column 203 being fixed to the mounting housing 201 on a side close to the support assembly 202. The elastic element 500 can be sleeved on the guide column 203, the guide 202b can be sleeved on the guide column 203 through the connecting through hole b1, and the elastic element 500 can be located between the mounting housing 201 and the guide 202b. In this way, after the elastic element 500 (for example, a spring) is sleeved on the guide column 203 fixed to the mounting housing 201, the guide 202b in the support assembly 202 can be sleeved on the guide column 203 through the connecting through hole b1. In this way, when the support body 202a moves in a direction close to the mounting housing 201, the guide 202b can be driven to move in a direction close to the mounting housing 201, and then the elastic element 500 can be pressed to be elastically deformed. For example, the number of the support bodies 202a can be one or more. When the number of the support bodies is more than one, adjacent two of the support bodies 202a are fixedly connected through an adapter B1, so that the plurality of support bodies 202a slide simultaneously.

In this case, by arranging the guide groove c1 matched with the support body 202a in the mounting shell 201, when the support body 202a moves towards the mounting shell 201, the end of the support body 202a towards the mounting shell 201 can slide in the guide groove c1. In this way, the guide groove c1 on the mounting shell 201 can not only avoid the sliding of the support body 202a, but also guide the sliding direction of the support body 202a.

The end of the recycling plate 400 may have a second sliding protrusion 404, at least a portion of which may be located within the auxiliary groove E1 (wherein, at least a portion of the second sliding protrusion may be located within a second planar groove in the auxiliary groove).

[0089] In the embodiments of this application, please refer to Figure 21 and Figure 23 , Figure 23 This is a partial structural schematic diagram of another display device provided in this application embodiment. The display device may further include: a driving component 1100, which can be connected to the first housing 100 and the second housing 200 respectively. The driving component can be configured to drive the second housing to slide relative to the first housing. In this case, by providing a driving component in the display device, the driving component 900 can drive the first housing 100 and the second housing 200 to slide relative to each other, thus effectively improving the user experience. For example, the display device may further include: an adapter F1, which can be connected to the driving component 1100 and the mounting shell 201 in the second housing respectively. In this application, the display device may further include: a control component (not shown in the figure), which is connected to the driving component, and the user can control the driving component to drive the first housing 100 and the second housing 200 to slide relative to each other through the control component. In this application, as Figure 23As shown, the driving assembly 1100 in the display device may include a driving motor 1101, a transmission shaft 1102, and a transmission component 1103. The driving motor 1101 may be fixed on the first housing 100, and the driving motor 1101 may be connected to one end of the transmission shaft 1102. The transmission component 1103 may be sleeved on the transmission shaft 1102, and the transmission component 1103 may be connected to the adapter F1. The driving motor 1101 in the driving assembly 1100 may be configured such that when it drives the transmission shaft 1102 to rotate, it causes the transmission component 1103 to move along the length direction of the transmission shaft 1102 (the length direction of the transmission shaft is parallel to the sliding direction of the second housing relative to the first housing), thereby causing the mounting shell 201 in the second housing 200 to slide relative to the first housing 100.

[0090] Optional, such as Figure 23 As shown, the display device may further include a fixed guide rail 1200 and a drive slider 1300. The fixed guide rail 1200 can be fixed on the first housing 100, and the length direction of the fixed guide rail 1200 can be parallel to the sliding direction of the second housing 200 relative to the first housing 100. The drive slider 1300 can be fixedly connected to the adapter F1, and the drive slider 1300 can be sleeved on the fixed guide rail 1200 and slidably connected to the fixed guide rail 1200. In this case, by setting the fixed guide rail 1200 and the drive slider 1300 to cooperate with each other, and setting the fixed guide rail 1200 on the first housing 100, and the drive slider 1300 on the adapter F1. Thus, during the relative sliding process between the mounting housing 201 and the adapter F1 and the first housing 100, the drive slider 1300 also slides relative to the fixed guide rail 1200. This restricts the direction of the second housing 200's relative sliding relative to the first housing 100 by the sliding direction of the drive slider 1300 relative to the fixed guide rail 1200. This ensures that the second housing 200 does not deviate during its relative sliding relative to the first housing 100.

[0091] In the embodiments of this application, please refer to Figure 24 , Figure 24This is an exploded view of the guide rods and guide grooves in the display device shown in an embodiment of this application. The second housing 200 in the display device may have a plurality of guide rods 206 arranged in parallel, and the length direction of each guide rod 206 may be parallel to the sliding direction of the second housing 200 relative to the first housing 100. In addition, the first housing 100 may have a plurality of guide grooves 101 corresponding one-to-one with the plurality of guide rods 206, and at least a portion of the guide rods 206 may be located in the corresponding guide grooves 101 and may be slidably connected to the corresponding guide grooves 101. In this case, through the one-to-one cooperation of the plurality of guide rods 206 and the plurality of guide grooves 101, while further ensuring the stable sliding of the second housing 200 relative to the first housing 101, a certain supporting effect can be provided for the flexible display panel 300.

[0092] In summary, this application provides a display device that may include: a first housing, a second housing, a flexible display panel, a retractable plate, and an elastic element. Since the rollable display portion of the flexible display panel needs to be rolled up, and the flexible display panel has a certain degree of flexibility, the retractable plate is fixedly connected to the back of the non-display portion of the flexible display panel, and the retractable plate is connected to the support assembly in the second housing. Thus, during the unfolding of the display device, as the rollable display portion of the flexible display panel slides out, the retractable plate moves along with the non-display portion; the retractable plate can move the support assembly closer to the mounting housing, thereby applying pressure to the elastic element through the support assembly; the elastic element, after being subjected to pressure, can apply a reaction force to the support assembly and the retractable plate, and then, through the retractable plate, apply a force opposite to the sliding direction of the non-display portion to the non-display portion of the flexible display panel, thereby tightening the flexible display panel in the X-axis direction and reducing the amount of screen crease arching and non-display portion warping along the X-axis direction during the rolling process of the flexible display panel. This effectively reduces the probability of unevenness in the overall area of ​​the flexible display panel, resulting in better overall flatness of the flexible display panel and thus better display effect of the display device.
