Abstract

This application discloses a display device, belonging to the field of display technology. The display device includes: a first housing, a second housing, a flexible display panel, a retractable plate, and an elastic element. During the unfolding process of the display device, the rolled-up display portion of the flexible display panel slides out, simultaneously driving the retractable plate to move via the non-display portion. The retractable plate can drive a support assembly to move closer to the mounting housing, thereby applying pressure to the elastic element through the support assembly. Upon receiving pressure, the elastic element can apply a reaction force to the support assembly and the retractable plate, which in turn applies a force to the non-display portion in the opposite direction of its sliding, thus tensioning the flexible display panel in the X-axis direction. This reduces the amount of screen arching and non-display portion warping along the X-axis during the rolling process of the flexible display panel. In other words, it effectively reduces the probability of unevenness appearing across the entire area of the flexible display panel.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic view showing the effect of folding and unfolding a flexible display panel in a display device according to an embodiment of the present application, fig. 2 is an exploded schematic view of a part of a structure of the display device according to an embodiment of the present application, and fig. 3 is a schematic view of a back side of a part of the structure of the display device according to an embodiment of the present application. The display device can be any product or component with the functions of displaying and scrolling, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. The display device may include a first housing 100, at least one second housing 200, a flexible display panel 300, a recycling board 400, and an elastic member 500.

The second housing 200 in the display device may be slidably coupled with the first housing 100. The second housing 200 may include a mounting case 201 and a support assembly 202 slidably coupled to the mounting case 201. Illustratively, the sliding direction of the support assembly 202 relative to the mounting housing 201 is parallel to the sliding direction of the mounting housing 201 relative to the first housing 100.

The flexible display panel 300 in the display device may include a flat display portion 301, a curled display portion 302, and a non-display portion 303, and the flat display portion 301 in the flexible display panel 300 may be fixed to the first case 100. The curled display portion 302 of the flexible display panel 300 may comprise a first portion 3021 arranged parallel to the flat display portion 301 and a second portion 3022 located between the first portion 3021 and the flat display portion 301, the second portion 3022 being wound around the side of the mounting case 201 facing away from the first housing 100. The non-display portion 303 in the flexible display panel 300 may be located on a side of the first portion 3021 facing away from the second portion 3022. The flexible display panel 300 generally has a display surface and a non-display surface disposed opposite to each other, and for convenience of description, the front surface of the flexible display panel is a surface on which the display surface is disposed, and the back surface of the flexible display panel is a surface on which the non-display surface is disposed.

The recycling board 400 in the display device may be fixedly coupled with the rear surface of the non-display portion 303 in the flexible display panel 300, and the recycling board 400 may be coupled with the support assembly 202.

The elastic member 500 in the display device may be located between the mounting case 201 and the support member 202, and both ends of the elastic member 500 may be in contact with the mounting case 201 and the support member 202, respectively.

During the unfolding process of the display device, the recovery plate 400 can drive the support assembly 202 to move towards the direction approaching to the mounting case 201, so as to apply pressure to the elastic element 500 through the support assembly 202.

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 bring the curled display portion 302 in the flexible display panel 300 to slide out of the second housing 200, and cause most of the display surface of the flat display portion 301 in the flexible display panel 300 and the display surface of the curled display portion 302 to be located in the same plane (cause the size of the area of the flexible display panel for displaying a picture to be increased), and be used for displaying a picture. When the second housing 200 in the display device slides in a direction approaching the first housing 100, the second housing 200 can drive the curled 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 300 for displaying the picture is reduced, and the portable display device is further facilitated.

In the present application, since the curled display portion 302 in the flexible display panel 300 needs to be rolled up, the flexible display panel 300 has a certain flexibility. Accordingly, by fixedly connecting the recovery plate 400 with the rear surface of the non-display portion 303 in the flexible display panel 300, and connecting the recovery plate 400 with the support member 202 in the second housing 200. In this way, during the unfolding process of the display device, the curled display portion 302 in the flexible display panel 300 slides out and simultaneously drives the recovery plate 400 to move through the non-display portion 303, the recovery plate 400 can drive the support assembly 202 to move towards the direction close to the mounting shell 201 so as to apply pressure to the elastic element 500 through the support assembly 202, the elastic element 500 can apply reaction force to the support assembly 202 and the recovery plate 400 after receiving the pressure, and further, the recovery plate 400 can apply force opposite to the sliding direction of the non-display portion 303 in the flexible display panel 300 to pull the flexible display panel 300 in the X-axis direction, so that the screen crease camber amount along the X-axis direction and the tilting amount of the non-display portion 303 in the sliding process of the flexible display panel 300 are reduced. That is, the probability of the uneven bad phenomenon occurring in the whole area of the flexible display panel 300 is effectively reduced, so that the flatness of the whole flexible display panel 300 is better, and the display effect of the display device is better.

In the embodiment of the present application, the first housing is a fixed housing in the slide display device, and the second housing is a movable housing in the slide display device.

In summary, the embodiment of the application provides a display device, which may include a first housing, a second housing, a flexible display panel, a recycling board, and an elastic element. Since the curled display portion in the flexible display panel requires a slide roll, the flexible display panel has a certain flexibility. Therefore, by fixedly connecting the recovery plate with the back surface of the non-display portion in the flexible display panel, and connecting the recovery plate with the support member in the second housing. In this way, the flexible display panel is stretched in the X-axis direction by applying a force opposite to the sliding direction of the non-display part to the non-display part of the flexible display panel through the recovery plate, so that the screen crease arch amount along the X-axis direction and the tilting amount of the non-display part in the flexible display panel sliding and rolling process are reduced. The probability of uneven bad phenomenon in the whole area of the flexible display panel is effectively reduced, so that the whole flatness of the flexible display panel is good, and the display effect of the display device is good.

Alternatively, the number of the second housings 200 in the display device may be one, and the second housings 200 may be located at any one of the opposite sides of the first housing 100 after the flexible display panel 300 is unfolded. As shown in fig. 1, the second housing 200 is located at the left side of the first housing 100 and is slidably coupled to the first housing 100. Referring to fig. 4, fig. 4 is a schematic view illustrating an effect of expanding and retracting a flexible display panel in another display device according to an embodiment of the application. The number of the second housings 200 in the display device may be two, after the flexible display panel 300 is unfolded, the two second housings 200 may be located at two sides of the first housing 100 opposite to each other, and both the two second housings 200 may be slidably connected with the first housing 100. For convenience of description, the following embodiments will be described by taking a sliding connection between a second housing and a first housing as an example.

In the embodiment of the present application, as shown in fig. 2, a side of the mounting case 201 in the second case 200 facing away from the first case 100 may have a circular arc shape. In this case, by providing the side of the mounting case 201 in the second housing 200 facing away from the first housing 100 in the shape of an arc, the second portion 3022 in the curl display portion 302 is wound on the side of the mounting case 201 facing away from the first housing 100. The curled display portion 302 in the flexible display panel 300 can smoothly transition through the side of the mounting case 201 facing away from the first housing 100, so that the curled display portion 302 can achieve a stable sliding connection with the side of the mounting case 201 facing away from the first housing 100. In an actual process, smooth connection of the curled display portion in the flexible display panel 300 to the side of the mounting case 201 facing away from the first case 100 may be achieved in a manner that reduces roughness of the side of the mounting case 201 facing away from the first case 100.

Alternatively, please refer to fig. 5, fig. 6, fig. 7, fig. 8 and fig. 9, in which fig. 5 is a schematic diagram of a part of a structure of another display device according to an embodiment of the present application, fig. 6 is a schematic diagram of a structure of a recovery board according to an embodiment of the present application, fig. 7 is a schematic diagram of a connection between a recovery board and a supporting component according to an embodiment of the present application, fig. 8 is a schematic diagram of a display device according to an embodiment of the present application in a contracted state, and fig. 9 is a schematic diagram of a display device according to an embodiment of the present application in an expanded state. The support assembly 202 in the display device may have a first sliding groove A1, and an extending direction of the first sliding groove A1 may be parallel to a sliding direction of the second housing 200 relative to the first housing 100 (i.e., a direction along an X axis in the drawing). The side of the recovery plate 400 in the display device facing away from the non-display portion 303 may have a first slider 401, and at least part of the first slider 401 may be located within a first chute A1 in the support assembly 202. During the unfolding process of the display device, the first slider 401 slides in the first chute A1 until the first slider abuts against the end of the first chute A1 near the mounting shell 201, and then drives the support assembly 202 to move in a direction near the mounting shell 201. By way of example, by providing the first slider 401 on the side of the recycling board 400 facing away from the non-display portion 303 in the flexible display panel 300, the first slider 401 may slide in cooperation with the first chute A1 provided in the support assembly 202. In this way, during the unfolding of the display device, the non-display portion 303 of the flexible display panel 300 drives the first slider 401 on the recovery plate 400 to slide in the first sliding groove A1 until the first slider 401 abuts against the end portion of the first sliding groove A1 near the mounting case 201, the first slider 401 drives the support assembly 202 to move in a direction near the mounting case 201 during the sliding, then, when the support assembly 202 moves in a direction near the mounting case 201, the elastic element 500 located between the mounting case 201 and the support assembly 202 applies pressure, and then, after the elastic element 500 is deformed under pressure, a reaction force is applied to the support assembly 202 and the recovery plate 400, and a tensioning force is applied to the non-display portion 303 of the flexible display panel 300 through the recovery plate 400, so as to tension the whole flexible display panel 300. For example, referring to fig. 10 and 11, fig. 10 is a cross-sectional view at A-A 'of fig. 9 when a display device provided in an embodiment of the present application is in an unfolded state, and fig. 11 is a cross-sectional view at B-B' of fig. 9 when a display device provided in an embodiment of the present application is in an unfolded state. The elastic element 500 may be a spring or a leaf spring. The elastic member 500 may gradually return to the original state during the shrinkage of the display device, for example, after the display device is in the shrunk state, the elastic member 500 is not pressed, i.e., is not elastically deformed.

In an embodiment of the present application, as shown in fig. 6, 7 and 8, the support assembly 202 in the display device may further have a limiting groove A2 in communication with the first chute A1, and the limiting groove A2 may be located at a side of the first chute A1 facing away from the recovery plate 400. The side of the recycling plate 400 facing away from the non-display portion 303 in the flexible display panel 300 may further have a spacing protrusion 402 fixedly coupled with the first slider 401, and at least a portion of the spacing protrusion 402 may be positioned in a spacing groove A2 in the support assembly 202. In this case, by providing a limit groove A2 communicating with the first slide groove A1 in the support member 202, a limit projection 402 is provided on the first slider 401. In this way, in the sliding process of the first slider 401 in the first sliding groove A1, the first slider 401 can be prevented from being separated from the first sliding groove A1 by matching the limiting groove A2 with the limiting protrusion 402, so that the first slider 401 is ensured to stably slide in the first sliding groove A1. In addition, the limiting groove A2 can play a good limiting role on the limiting protrusion 402, and even if the flexible display panel 300 has a warping trend at the tail end in the process of rolling, the flexible display panel 300 can be fixed through the cooperation of the limiting groove A2 and the limiting protrusion 402. For example, the limiting groove A2 in the support assembly 202 may have a first groove A1 communicating with the first sliding groove A1, and two second grooves A2 distributed at both sides of the first groove A1. The number of the limit protrusions 402 fixedly connected with the first slider 401 may be two, a part of the first slider 401 passes through the first chute A1 and then is located in the first chute A1, and the two limit protrusions 402 fixedly connected with the first slider 401 may be located in the two second chute a2 respectively. In this case, the limiting groove A2 comprises a first groove body A1 communicated with the first sliding groove A1 and two second groove bodies A2 distributed on two sides of the first groove body A1, and the two limiting protrusions 402 are respectively located in the two second groove bodies A2, so that the limiting effect of the limiting groove A2 on the limiting protrusions 402 is further ensured.

Alternatively, referring to fig. 8 and 12, fig. 12 is an exploded view of a portion of another display device according to an embodiment of the present application. The support assembly 202 in the display device may include a support body 202a slidably coupled with the recovery plate 400, and a guide 202b fixedly coupled with at least one side of the support body 202a, the support body 202a may have a first sliding groove A1, and the guide 202b may have a coupling through hole b1. The second housing 200 in the display device may further include a guide post 203, and one end of the guide post 203 may be fixed to a side of the mounting case 201 near the support assembly 202. The elastic member 500 may be sleeved on the guide post 203, the guide 202b may be sleeved on the guide post 203 through the connection through hole b1, and the elastic member 500 may be located between the mounting case 201 and the guide 202 b. Thus, after the elastic member 500 (e.g., a spring) is coupled to the guide post 203 fixedly coupled to the mounting case 201, the guide 202b of the support assembly 202 may be coupled to the guide post 203 through the coupling through hole b1. In this way, when the support body 202a moves in a direction approaching the mounting case 201, the guide 202b can be driven to move in a direction approaching the mounting case 201, and further, a pressure can be applied to the elastic member 500 to elastically deform it. For example, the number of the support bodies 202a may be 1 or more, and when the number of the support bodies is plural, two adjacent support bodies in the plurality of support bodies 202a are fixedly connected through the adaptor B1, so that the plurality of support bodies 202a slide simultaneously. In the present application, as shown in fig. 10 and 12, the guide 202b may further have a limiting hole b2 communicating with the connection through hole b1 at a side near the mounting case 201, and a portion of the elastic member 500 may be located in the limiting hole b 2. Thus, by extending a portion of the elastic member 500 into the limiting hole b2, the elastic member 500 has a low probability of being bent and deformed during the compression and deformation of the elastic member 500 (e.g., a spring), and plays a role of compression limiting, and the compression amount of the spring is controlled to control the tension force to the non-display portion. In addition, in order to secure the connection stability of the guide 202b and the guide post 203, the second housing 200 may further include a fastener 204, and the fastener 204 may be fixedly connected to the other end of the guide post 203 to limit the guide 202b between the fastener 204 and the mounting case 201.

In an embodiment of the present application, as shown in fig. 12, the mounting case 201 in the second case 200 may have a guide groove c1 to be engaged with the support body 202a, and an end of the support body 202a toward the mounting case 201 may be located in the guide groove c1 on the mounting case 201. In this case, by providing the guide groove c1 that mates with the support body 202a in the mounting case 201, the support body 202a can slide in the guide groove c1 toward the end of the mounting case 201 when moving in the direction approaching the mounting case 201.
