Description

Technical Field

[0001] This utility model relates to the field of LED screen technology, and in particular to a rollable screen. Background Technology

[0002] A display screen is an electronic output device used to present visual information, converting electronic signals into optical information perceptible to humans through images, text, or video. It is the core interface for human-computer interaction and is widely used in various electronic products such as mobile phones, televisions, computers, in-vehicle systems, and smart wearable devices. Currently, mainstream screens are mainly divided into two categories: rigid screens and flexible screens, but both have significant limitations: rigid screens are limited by their fixed shape and cannot simultaneously achieve large-size display and portability; foldable screens, while achieving a certain degree of deformability, suffer from obvious creases, complex hinge structures, poor durability, and a lack of adaptability to different scenarios. Utility Model Content

[0003] The main purpose of this utility model is to provide a rollable screen that can be rolled up for storage and laid flat for use, combining large size and portability, while being easy to install and highly adaptable to various scenarios.

[0004] To achieve the above objectives, this utility model proposes a rollable screen, comprising:

[0005] Multiple display components, each comprising a display layer, a flexible base layer, and a support member stacked sequentially, wherein each display component has two back-to-back bonding edges, and any two bonding edges of the display components can be bonded and abutted against each other.

[0006] A connecting component includes multiple fixing pieces and a connecting cable. The multiple fixing pieces are respectively disposed on the side of each support member away from the display layer. At least one mounting groove is formed between the fixing pieces and the support member. The mounting grooves on the multiple support members together form a mounting channel. The connecting cable passes through the mounting channel.

[0007] In one possible implementation, the support member includes a column and a support plate, with one side of the column abutting against the flexible base layer and the other side perpendicularly connected to the support plate.

[0008] In one possible implementation, the side edge of the support plate is vertically connected to a first auxiliary plate on the side facing the flexible base layer, and a gap is left between the first auxiliary plates of any two adjacent support members.

[0009] In one possible implementation, the first auxiliary plate is bent to form a second auxiliary plate on the side facing the flexible base layer, and the second auxiliary plate is attached to the flexible base layer.

[0010] In one possible implementation, the side edge of the support plate is provided with a reinforcement on the side away from the flexible base layer.

[0011] In one possible implementation, the reinforcing part has a fixing groove at a position corresponding to the connecting cable.

[0012] This utility model's technical solution utilizes a three-layer stacking of the display layer, flexible base layer, and support components, combined with a nested design of columns, support plates, and double auxiliary plates. This ensures both flexible bending capability and prevents deformation and damage through edge reinforcement. The connecting components form a continuous installation channel through fixing plates and mounting grooves, while the fixing grooves on the reinforcing parts precisely constrain the connecting cables, ensuring that all display components move synchronously during bending without misalignment or jamming. The fitting edge and gap design allows for fine-tuning of displacement between components, reducing frictional loss, while the reinforcing parts and fixing grooves disperse stress, significantly improving the lifespan of repeated bending. Modular splicing and local reinforcement stabilize key areas while avoiding redundancy in the overall structure. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Reference Figures 1 to 4 This utility model proposes a rollable screen, including multiple display components and connecting components. The display components include a display layer 1, a flexible base layer 2, and a support member 3 stacked in sequence. The display components have two back-to-back bonding edges 4, and the bonding edges 4 of any two display components can be bonded to each other. The connecting components include multiple fixing pieces 5 and connecting cables 6. The multiple fixing pieces 5 are respectively disposed on the side of each support member 3 away from the display layer 1. At least one mounting groove 51 is formed between the fixing pieces 5 and the support member 3. The mounting grooves 51 on the multiple support members 3 together form an installation channel, and the connecting cable 6 passes through the installation channel.

[0023] Understandably, each display component consists of three layers of material stacked sequentially. The display layer 1 is the outermost layer, responsible for displaying images, such as OLED or flexible screens; the flexible base layer 2 is the middle layer, with a flexible material ensuring the screen can be bent; and the support component 3 is the bottom layer, providing structural support, and can be a rigid or semi-rigid material. Each display component has two back-to-back bonding edges 4, namely the left and right edges. Multiple display components are bonded together through the bonding edges 4 to form a continuous large screen.

[0024] The fixing plate 5 is fixed to the back of each support member 3. The side of the fixing plate 5 that mates with the support member 3 has at least one groove or channel, forming a mounting groove 51. After the mounting grooves 51 of all display components are aligned, they together form a continuous mounting channel. The connecting cable 6 is a flexible rope, such as a metal cable or high-strength fiber, that runs through the entire mounting channel, connecting all display components together to maintain the linkage and flexibility of the overall structure. When all display components bend or unfold synchronously, they will pull or retract the connecting cable 6.

[0025] The design of the fitting edge 4 in this embodiment ensures that the screen can be seamlessly spliced ​​when unfolded and tightly folded when rolled up; the combination of the flexible base layer 2 and the support member 3 takes into account both flexibility and rigidity, avoiding screen deformation and damage; the fixing piece 5 and the connecting cable 6 of the connecting component provide mechanical strength to achieve stable rolling.

[0026] Reference Figure 4 In one embodiment of this utility model, the support member 3 includes a column 31 and a support plate 32. One side of the column 31 abuts against the flexible base layer 2, and the other side is perpendicularly connected to the support plate 32.

[0027] Understandably, one side of the column 31 abuts against the flexible base layer 2, directly contacting the flexible base layer 2 of the display component, thus supporting the display layer 1 and the flexible base layer 2. The other end of the column 31 is connected to the support plate 32 at a perpendicular angle, forming a T-shaped structure. The support plate 32 is made of a rigid material such as reinforced plastic, which can expand the support area, distribute the force, and avoid local deformation. When the rollable screen is bent, the connecting cable 6 is pulled, and the support plate 32 transmits the force through the fixing piece 5, causing the column 31 and the flexible base layer 2 to bend synchronously, and the display layer 1 deforms flexibly accordingly.

[0028] Reference Figure 4 In one embodiment of the present invention, a first auxiliary plate 33 is vertically connected to the side edge of the support plate 32 facing the flexible base layer 2, and a gap is left between any two adjacent first auxiliary plates 33 of the support member 3.

[0029] Understandably, the first auxiliary plate 33 is an extension of the support plate 32, further enhancing the lateral support capability. The first auxiliary plate 33 is located at the side edge of the support plate 32 and extends vertically from the support plate 32 toward the display layer 1, forming an "L" shaped structure with the support plate 32 to form a rigid support.

[0030] When multiple display components are spliced ​​together through the bonding edge 4, the first auxiliary plate 33 of the adjacent support 3 does not directly contact each other, but retains a certain gap to avoid rigid collision: during the rolling or unfolding process, it prevents the adjacent auxiliary plates from being damaged due to friction or compression; at the same time, it allows flexible deformation: the gap provides local bending space for the flexible base layer 2 and the display layer 1, avoiding excessive stress concentration when the screen is folded.

[0031] Reference Figure 4 In one embodiment of the present invention, the first auxiliary plate 33 is bent to form a second auxiliary plate 34 on the side facing the flexible base layer 2, and the second auxiliary plate 34 is attached to the flexible base layer 2.

[0032] Understandably, the second auxiliary plate 34 is formed by bending the top of the first auxiliary plate 33 (i.e., the side facing the flexible base layer 2). It can be a right-angle bend or an arc transition. After bending, the second auxiliary plate 34 and the first auxiliary plate 33 form an "L-shaped" continuous structure.

[0033] The plane of the second auxiliary plate 34 is directly attached to the back of the flexible base layer 2, forming an additional support surface and enhancing local support. By attaching to the flexible base layer 2, the pressure of the display layer 1 is dispersed, preventing the screen from deforming or creased due to local suspension when it is rolled up. The bending design allows the second auxiliary plate 34 to adjust its angle slightly when the screen is rolled up, avoiding stress concentration caused by rigid connection.

[0034] Reference Figure 4In one embodiment of the present invention, a reinforcing part 35 is provided on the side edge of the support plate 32 away from the flexible base layer 2.

[0035] Understandably, the reinforcement 35 is located on the side edge of the support plate 32, on the side away from the flexible base layer 2, that is, on the back of the support plate 32, on the same side as the fixing piece 5. The reinforcement 35 can be a raised rib, a thickened metal block, or an additional hard coating, used to improve the local structural strength. In this example, the reinforcement 35 is a raised beam.

[0036] Reference Figure 4 In one embodiment of the present invention, the reinforcing part 35 has a fixing groove 36 at a position corresponding to the connecting cable 6.

[0037] Understandably, the fixing groove 36 is located on the reinforcing part 35 and corresponds to the path of the connecting cable 6. It can limit and fix the connecting cable 6, preventing it from shifting laterally or coming out of the installation channel during the coiling process. The fixing groove 36 can be made of a low-friction material or have a smooth inner wall to ensure smooth sliding of the connecting cable 6. At the same time, it avoids the tension of the connecting cable 6 from being concentrated at a certain point, but instead transmits it evenly to the reinforcing part 35 through the fixing groove 36. After the connecting cable 6 passes through the fixing groove 36, its movement trajectory is more stable, and it will not generate unnecessary friction or collision with the inner wall of the installation channel during coiling.

[0038] This utility model's technical solution employs a three-layer stacking of display layer 1, flexible base layer 2, and support component 3, combined with a nested design of column 31, support plate 32, and double auxiliary plates. This ensures flexible bending capability while preventing deformation and damage through edge reinforcement. The connecting components form a continuous installation channel through fixing plate 5 and mounting groove 51, and the fixing groove 36 on the reinforcing part 35 precisely constrains the connecting cable 6, ensuring that all display components move synchronously without misalignment or jamming during curling. The fitting edge 4 and gap design allow for fine-tuning of displacement between components, reducing frictional loss, while the reinforcing part 35 and fixing groove 36 disperse stress, significantly improving the lifespan of repeated curling. Modular splicing and local reinforcement stabilize key areas while avoiding redundancy in the overall structure.
