Description

Technical Field

[0001] This invention relates to the field of design and manufacturing technology of flexible folding devices, and in particular to a rollable display device and electronic device. Background Technology

[0002] With the continuous improvement of display panel manufacturing technology, people have higher requirements for the quality and overall performance of display panels and devices.

[0003] In recent years, with the widespread application of Organic Light Emitting Diode (OLED) screens, flexible foldable panels and devices have become an important focus for manufacturers and researchers. Because OLED screens are bendable, foldable panels using flexible OLEDs can better achieve screen bending and folding, resulting in larger screen areas and greater portability. Currently, large displays are rare due to their inconvenience in portability. When large displays are needed outdoors, significant manpower and resources are required for setup to meet temporary outdoor needs. Therefore, existing large flexible display panels and rollable display devices often suffer from problems such as large size, inconvenience in movement, and limited application scenarios. For example, the commonly seen rollable TVs mainly consist of a curved screen, a rolling drum, and a motor mechanism. During movement or transport, the curved screen needs to be rolled onto the rolling drum, ensuring the large curved screen fits snugly against the drum before being moved. However, commonly used rollable rollers often weigh over 100 kg. While they can reduce the size of curved screens, their weight makes them difficult to handle and move. This limits their application scenarios and hinders further improvements in the overall performance of rollable display devices.

[0004] In summary, in the prior art, the flexible rollable display device is relatively large in size, making it difficult to transfer or transport, and its application scenarios are limited, which is not conducive to further improvement and enhancement of the overall performance of the rollable display device. Summary of the Invention

[0005] This invention provides a rollable mechanism and an electronic device. This effectively addresses the problems of existing large rollable display devices being too large to move or transport, and having limited application scenarios, thus hindering further improvements in their overall performance.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a rollable display device, comprising:

[0007] Flexible display panels and roll-up mechanisms;

[0008] The curling mechanism includes an adsorption support, an adjustment bracket, and a driving mechanism, wherein the adsorption support is fixed to the back of the flexible display panel;

[0009] The adjusting bracket is located on the side of the adsorption support member away from the flexible display panel, and the adjusting bracket drives the adsorption support member to unfold or fold relative to it, causing deformation of the flexible display surface and the corresponding portion of the curling mechanism; and,

[0010] A driving mechanism is fixed on the side of the adjustment bracket away from the adsorption support member, and the driving mechanism is used to drive the adjustment bracket.

[0011] According to one embodiment of the present invention, the adsorption support includes a plurality of adsorption strips spaced apart along a first direction, wherein the direction in which the flexible display panel deforms is parallel to the first direction.

[0012] According to one embodiment of the present invention, the density of the adsorption strips at the edge of the flexible display panel is greater than the density of the adsorption strips at the center region of the flexible display panel.

[0013] According to one embodiment of the present invention, the adsorption strip includes a magnetic strip, and the magnetic properties of two adjacent adsorption strips are opposite.

[0014] According to one embodiment of the present invention, the adjustment bracket includes support rods, which are arranged crosswise on one side of the flexible display panel, and the intersection of the support rods is located at the geometric center of the flexible display panel.

[0015] According to one embodiment of the present invention, the support rod includes a first support rod, a second support rod, and a movable connection point. One end of the movable connection point is fixed to the adsorption support member. The first support rod and the second support rod are arranged intersectingly and can rotate relative to the movable connection point.

[0016] According to one embodiment of the present invention, the flexible display panel is rolled up from the edge to the center along a first direction, and when the flexible display panel is fully rolled up, the first support rod and the second support rod coincide.

[0017] According to one embodiment of the present invention, the driving mechanism includes a driving electrode and a transmission member disposed on the driving electrode. The transmission member is connected to the adjusting bracket and is used to drive the adjusting bracket to move.

[0018] According to one embodiment of this application, the adjustment bracket has a first supporting area relative to the flexible display panel at a first moment, and the adjustment bracket has a second supporting area relative to the flexible display panel at a second moment, wherein the first supporting area is greater than the second supporting area.

[0019] According to a second aspect of the present invention, an electronic device is also provided, which includes the rollable display device provided in the embodiments of the present application.

[0020] The beneficial effects of this invention are as follows: Compared with the prior art, this application provides a rollable display device and electronic device. The rollable display device includes a flexible display panel and a rollable mechanism. The rollable mechanism includes an adsorption support, an adjustment bracket, and a driving mechanism. The adsorption support, adjustment bracket, and driving mechanism are all disposed on the back of the flexible display panel. The driving mechanism drives the adjustment bracket, which in turn causes the adsorption support to unfold or fold relative to itself, thereby causing deformation of the corresponding portion of the flexible display panel and the rollable mechanism. In this application embodiment, the driving mechanism drives the adjustment bracket, which controls the relative area between the rollable mechanism and the flexible display panel, thereby enabling the unfolding or folding of the flexible display panel. This simplifies the structure of the rollable display device and improves its ease of operation. Attached Figure Description

[0027] In the following detailed description, only certain embodiments of the invention are shown and described by way of simple illustration. As will be understood by those skilled in the art, the embodiments described herein can be modified in various ways without departing from the spirit or scope of the invention.

[0028] In the accompanying drawings, the thickness of layers, films, plates, regions, etc., may be exaggerated for clarity, better understanding, and ease of description. It should be understood that when an element such as a layer, film, region, or substrate is referred to as "located on another element," it may be located directly on the other element or there may be inserted elements.

[0029] Furthermore, unless explicitly stated otherwise, the word "including" and its variations such as "comprising" or "containing" will be understood to imply the inclusion of the discussed element, but not necessarily the exclusion of other elements. Further, in the specification, the phrase "on" means placed above or below the object part, and not necessarily on the upper side of the object part based on the direction of gravity.

[0030] It will be understood that although the terms “first,” “second,” etc., may be used in this document to describe various components, these components should not be limited by these terms. These terms are used only to distinguish one component from another.

[0031] As used in this article, the singular forms “one,” “a,” and “the” are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0032] It will also be understood that the terms “comprising” and / or “including” as used herein specify the presence of the said feature or component, but do not exclude the presence or addition of one or more other features or components.

[0033] It will be understood that when a layer, region, or component is referred to as being "formed on" another layer, region, or component, it can be formed directly or indirectly on that other layer, region, or component. For example, intermediate layers, regions, or components may exist.

[0034] In the following examples, the x-axis, y-axis, and z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or they can represent different directions that are not perpendicular to each other.

[0035] This application provides a rollable display device and an electronic device to effectively simplify the rolling mechanism of the rollable display device and effectively improve the rolling effect and overall performance of the rollable display device.

[0036] like Figure 1 As shown, Figure 1This is a schematic diagram of a rollable display device provided in an embodiment of this application. In this embodiment, the rollable display device may include a flexible display panel 101 and a rolling mechanism 18. The rolling mechanism 18 may be disposed on the back side of the flexible display panel 101, and the unfolding and rolling of the flexible display panel 101 are controlled through the rolling mechanism 18. Specifically, the rolling mechanism 18 may include an adsorption support 102, an adjustment bracket 103, and a driving mechanism 104.

[0037] Specifically, when setting up the above-mentioned components and structures, the flexible display panel 101 is described using a flexible OLED display as an example. The size of the OLED display can be set according to the specifications of different products. When a large-size display is required, the flexible OLED display panel is unfolded. When it needs to be transported or moved, the flexible OLED is rolled up to reduce its area and achieve convenient transport.

[0038] Meanwhile, the adsorption support 102 is disposed on the side of the flexible display panel 101 away from the light emission side, such as on the back side of the flexible display panel 101. When used with a rollable display device, the adsorption support 102 and other rollable components are disposed inside the rollable display device, thereby avoiding the influence of the components on the display effect of the display area.

[0039] In this embodiment, the adsorption support 102 is mainly used to provide a curling force for the flexible display panel, such as providing an adsorption force to the flexible display panel, which automatically rolls up under the action of the adsorption force. Therefore, the adsorption support 102 may include a magnetic component or other adsorption components. In the following embodiments, when the adsorption support 102 is provided, it may include a plurality of adsorption strips spaced apart along a first direction, wherein the first direction is parallel to the direction in which the flexible display panel 101 deforms. Specifically, the adsorption support 102 is configured as an adsorption strip, and a magnetic adsorption strip 1021 is used as an example for explanation.

[0040] Specifically, the magnetic adsorption strip 1021 can be directly attached to the back of the flexible display panel 101, and the length direction of the magnetic adsorption strip 1021 can be arranged parallel to the length direction of the flexible display panel 101. That is, the length direction of the magnetic adsorption strip 1021 is perpendicular to the direction in which the flexible display panel 101 is curled. In this way, the magnetic adsorption strip 1021 will not block the curling of the flexible display panel 101, thereby improving its curling performance.

[0041] Furthermore, when setting the aforementioned multiple magnetic adsorption strips 1021, since the curling effect and corresponding curling force vary in different areas when the flexible display panel is rolled up, in this embodiment, to better match the curling force, the arrangement density of the magnetic adsorption strips 1021 at the two edge positions of the flexible display panel 101 can be greater than the arrangement density of the magnetic adsorption strips 1021 at the center area of ​​the flexible display panel. In this way, on the one hand, the magnetic adsorption strips 1021 can support the edge of the flexible display panel; on the other hand, the magnetic adsorption strips can increase the adsorption curling force at the edge, making it easier for the flexible display panel 101 in the edge area to curl up, thereby improving the curling effect of the flexible display panel.

[0042] like Figure 2 As shown, Figure 2 This is a schematic diagram of another rollable display device provided in an embodiment of this application. In this embodiment, since the magnetic adsorption strip 1021 is mainly used to provide adsorption force to the flexible display panel 101, the way the magnetic adsorption strip 1021 is arranged directly affects the rollability of the flexible display panel.

[0043] Combination Figure 1 In this embodiment of the application, the magnetic adsorption support is configured such that the magnetic adsorption strip 1021 further includes a first magnetic adsorption strip 1021 and a second magnetic adsorption strip 1022. The first magnetic adsorption strip 1021 is positioned close to the edge of the flexible display panel 101, and the second magnetic adsorption strip 1022 is sequentially positioned inwards from the edge of the flexible display panel. Furthermore, the first magnetic adsorption strip 1021 is a complete elongated structure, with a length greater than that of the second magnetic adsorption strip 1022. Thus, the first magnetic adsorption strip 1021 can support the entire edge of the flexible display panel.

[0044] Meanwhile, when setting the second magnetic adsorption strip 1022 on the side away from the edge region, the second magnetic adsorption strip 1022 can be arranged in an array and spaced apart on the back of the flexible display panel, such as in an array relative to the rows and columns of the flexible display panel 101. Furthermore, within the first region 221 on the left and right sides of the flexible display panel 101, the length of the second magnetic adsorption strip 1022 can be less than the length of the second magnetic adsorption strip 1022 in the second region 222 near the center of the flexible display panel 101. In this way, the second magnetic adsorption strip 1022 in the second region 222 can provide a larger support area to prevent problems such as the flexible display panel collapsing in the center region.

[0045] Furthermore, such as Figure 3 As shown, Figure 3 This is a schematic diagram of yet another curled structure provided in the embodiments of this application. Combined with... Figures 1-2In the structure described in this embodiment, when setting the aforementioned adsorption support, the magnetic adsorption strip 102 may further include a third magnetic adsorption strip 1023. Specifically, the first magnetic adsorption strip 1021 is disposed on the side close to the flexible display panel 101, and the first magnetic adsorption strip 1021 is continuously disposed, that is, the length of the first magnetic adsorption strip 1021 is greater than the lengths of the second magnetic adsorption strip 1022 and the third magnetic adsorption strip 1023. Meanwhile, the third magnetic adsorption strip 1023 is disposed on the side of the second magnetic adsorption strip 1022 away from the first magnetic adsorption strip 1021. Furthermore, the third magnetic adsorption strip 1023 is offset from the second magnetic adsorption strip 1022.

[0046] Specifically, the third magnetic adsorption strip 1023 is positioned at the corresponding gap between two adjacent second magnetic adsorption strips 1022. In this way, the third magnetic adsorption strip 1023 and the second magnetic adsorption strips 1022 can complement each other, effectively supporting the flexible display panel and providing the necessary adsorption force for the rollable display device.

[0047] In this embodiment, when the flexible display panel 101 is rolled up, it rolls inward or towards the center along a first direction, eventually forming a cylindrical shape. Therefore, the magnetic properties of the magnetic adsorption strips in adjacent rows are opposite. Optionally, adjacent magnetic adsorption strips in the same row can also have the same magnetic properties, so that dissimilar magnetic properties repel each other within the same row, thereby preventing folding and wrinkling of the flexible display panel.

[0048] See details Figure 1 Furthermore, in this embodiment, the rollable display device also includes an adjustment bracket 103. The adjustment bracket 103 is disposed on the side of the adsorption support member away from the flexible display panel, such as on the outer side of the adsorption support member, and is fixedly connected to it. The adjustment bracket 103 primarily drives the adsorption support member to unfold or fold relative to itself, thereby causing deformation of the corresponding portion of the flexible display panel and the rolling mechanism. During the rolling process of the flexible display panel, the relative support area between the adjustment bracket and the flexible display panel changes, thus achieving the rolling effect of the flexible display panel. Specifically, when the flexible display panel is rolled, it rolls from a larger size to a smaller size.

[0049] Therefore, the adjustment bracket dynamically adapts to the flexible display panel. During the rolling process, at a first moment, the adjustment bracket 103 has a first supporting area on the flexible display panel, which can also be understood as the area of ​​the flexible display panel unfolded. At a second moment, the adjustment bracket 103 has a second supporting area on the flexible display panel, wherein the first supporting area is larger than the second supporting area. In this embodiment, the adjustment bracket 103 is controlled by the driving mechanism to change the size of the supporting area of ​​the adjustment bracket 103 on the flexible display panel, thereby achieving the rolling effect.

[0050] Specifically, the adjustment bracket 103 may include multiple support rods. In this embodiment, the adjustment bracket 103 may also be configured as a magnetic bracket, where the magnetism on the adjustment bracket interacts with the magnetism on the adsorption strip to further improve the unfolding and support of the flexible display panel. In the following embodiments, the adjustment bracket 103 includes a first support rod 1031 and a second support rod 1032. The first support rod 1031 and the second support rod 1032 are movably connected. The first support rod 1031 and the second support rod 1032 are arranged intersectingly and have an intersection point 105.

[0051] In this embodiment of the application, when the above-mentioned intersection point 105 is set, the intersection point 105 can be located at the geometric center of the flexible display panel 101. For example, when the flexible display panel 101 is unfolded into a rectangular screen, the intersection point 105 is located at the intersection of the diagonal connecting lines of the rectangle, thereby ensuring the support effect of the first support rod and the second support rod on the flexible display panel.

[0052] Meanwhile, in this embodiment, when the flexible display panel 101 is in use, such as when it is fully unfolded, the first support rod 1031 and the second support rod 1032 also intersect, and the four ends of the support rods respectively support the four corners of the flexible display panel 101, thereby maintaining the unfolding of the flexible display panel.

[0053] In this embodiment, the lengths of the first support rod and the second support rod 1032 meet the length of the flexible display panel, thereby preventing the first support rod 1031 and the second support rod 1032 from intersecting and extending beyond the perimeter of the flexible display panel, thus preventing interference with the flexible display panel.

[0054] Furthermore, a movable connection point is provided at the intersection 105, through which the first support rod 1031 and the second support rod 1032 are connected and fixed to the adsorption support, thereby preventing the first support rod 1031 and the second support rod 1032 from falling off during rotation.

[0055] In this embodiment, the rollable display device further includes a driving mechanism 104. Specifically, the driving mechanism 104 is disposed on the back side of the flexible display panel. Optionally, the driving mechanism 104 is fixedly disposed on the side of the adjusting bracket 103 away from the adsorption support member 102. The driving mechanism 104 also includes a drive motor 107, a first transmission member 106, and a second transmission member 108.

[0056] The first transmission component 106 can be connected to the first support rod 1031, and the second transmission component 108 can be connected to the second support rod 1032. During connection, the corresponding support rods of the first transmission component 106 and the second transmission component 108 can move relative to each other, thereby preventing interference between the flexible display panel and the support rods during the rolling process.

[0057] See details Figure 1 In this example, the structure of the drive mechanism 104 is merely an illustration. During the rollable display device's roll-up process, the drive motor 107 in the drive mechanism 104 moves and drives the first transmission member 106 and the second transmission member 108. The first transmission member 106 and the second transmission member 108 will apply force to the first support rod 1031 and the second support rod 1032, causing the first support rod 1031 and the second support rod 1032 to move relative to each other. That is, the acute angle between the first support rod 1031 and the second support rod 1032 decreases. At this time, the support area of ​​the first support rod 1031 and the second support rod 1032 on the flexible display panel 101 decreases.

[0058] like Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the rollable display device in an embodiment of this application. (In conjunction with...) Figure 1 In this embodiment of the structure, under the action of the driving mechanism 104, the first support rod 1031 and the second support rod 1032 rotate relative to their intersection point 105. Due to the rotation of the two support rods, they no longer support the first magnetic adsorption strip 1021 at the edge. Under the action of magnetic attraction, the first magnetic adsorption strip 1021 curls and retracts towards the center of the flexible display panel. Meanwhile, the magnetic adsorption strips at other parts supported by the two support rods cannot curl. At this time, the upper part of the flexible display panel 101 curls and forms a first curled area 1011, and the lower edge of the flexible display panel 101 curls and forms a second curled area 1012.

[0059] As the driving mechanism moves further, the supporting area of ​​the first support rod 1031 and the second support rod 1032 on the flexible display panel will further decrease, and the acute angle between the first support rod 1031 and the second support rod 1032 will further decrease. Simultaneously, the curled area of ​​the first curled area 1011 and the second curled area 1012 will further increase. When the first support rod 1031 and the second support rod 1032 overlap, the number of magnetic adsorption strips supported by the first support rod 1031 and the second support rod 1032 is minimized. Since the flexible display panel is no longer supported by the support rods, it completely curls up, forming a roll-up screen. This roll-up screen has a smaller size and area, making it easier to carry and transport.

[0060] like Figure 5 As shown, Figure 5 This is a simplified schematic diagram of the driving mechanism of the rollable display device provided in the embodiments of this application. (In conjunction with...) Figure 1 In the structure of the rollable display device in this application embodiment, when the driving mechanism is used, one end of the driving mechanism 104 can be fixed to the magnetic adsorption strip. During fixing, it can be fixed by the fixing part 555 on the driving mechanism 104. At the same time, the driving motor 107 can also be fixed by the fixing part 555, thereby ensuring the reliability and firmness of the driving mechanism.

[0061] In this embodiment, the main structure of the drive mechanism 104 can be configured as a coupling and connecting rod device, as detailed below. Figure 5 In this example, the drive mechanism 104 is described using a connecting rod as an example. When the drive mechanism is in motion, the connecting rod extends or retracts. Specifically, when the flexible display panel is rolled up, the connecting rod in the drive mechanism gradually changes from a stretched state to a retracted state. When the flexible display panel is unfolded, the connecting rod in the drive mechanism gradually changes from a retracted state to a stretched state, thus synchronizing with the unfolding and rolling of the flexible display panel and realizing the rolling and unfolding of the device.

[0062] In this embodiment, the flexible display panel is unfolded or folded using the different structures described above. Specifically, the driving mechanism drives the adjusting bracket, which in turn drives the adsorption support to unfold or fold relative to each other, causing the corresponding portion of the flexible display panel and the rolling mechanism to deform, thereby causing the flexible display panel to roll up.

[0063] See details Figure 5 In this embodiment of the application, the connecting rod 109 in the drive mechanism 104 is provided with multiple connection nodes. Such as the first connection node 1061 in the middle region of the connecting rod 109 and the second connection node 1081 on the side away from the fixed part 555.

[0064] In this embodiment, a first transmission member 106 is provided at the first connecting node 1061, and a second transmission member 108 is provided at the second connecting node 1081. During operation, the drive motor 107 can provide force to the first transmission member 106 and the second transmission member 108 through a conveyor belt or torque device, causing the first transmission member 106 and the second transmission member 108 to drive the first support rod 1031 and the second support rod 1032 to move. In this embodiment, the length of the connecting rod 109 can be extended or shortened under the control of the drive motor 107. During the change, the first transmission member 106 and the second transmission member 108 on the connecting rod 109 drive the corresponding support rod to move, reducing the support area of ​​the support member on the flexible display panel, thereby realizing the winding of the flexible display panel.

[0065] Furthermore, when setting the structure of the connecting rod 109, the number of connecting rods 109 can be adjusted according to the width of the flexible display panel 101 to ensure that the connecting rod can effectively adjust the support rod and ensure its control effect. In this embodiment, the drive motor 107 on the drive mechanism can be set as a stepper motor or a servo motor to achieve fine adjustment and control the rolling effect of the flexible display panel to meet people's usage needs.

[0066] In this embodiment of the application, when setting the rollable display device, by simplifying the internal components of the rollable display device and controlling the weight of the rollable display device to be less than 15Kg, the weight of the rollable display device is effectively reduced while reducing the area size of the rollable display device, and the overall performance of the rollable display device is improved.

[0067] Furthermore, in this embodiment of the application, an electronic device is also provided, which may be a touch electronic device, and the electronic device includes the rollable display device provided in this embodiment of the application. When the rollable display device is used, the flexible display panel in the electronic device can be bent better and its unfolded area is reduced, which is more conducive to long-distance transportation and further improves its application scenarios.

[0068] Specifically, the rollable display device and electronic equipment can be applied to any product or component with display and bending or folding functions, such as large-size displays and projection screens, and there are no specific restrictions on its specific type.

[0069] In summary, the rollable display device and electronic device provided by the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the technical solution and core ideas of the present invention. Although the present invention has been disclosed above with preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is based on the scope defined by the claims.
