Description

Technical Field

[0001] This utility model belongs to the field of flexible screen technology, and more specifically, it relates to an inwardly folding flexible screen. Background Technology

[0002] Foldable flexible screens are an advanced display technology based on the combination of bendable OLED display materials and flexible substrates. The core of this technology lies in utilizing the bendable properties of flexible electronic materials, combined with a high-precision and high-reliability mechanical hinge structure, so that smart terminal devices can provide a large display area close to that of a tablet computer when unfolded, while maintaining a compact size similar to that of a traditional smartphone when folded. This combines the dual advantages of the portability of mobile devices and the immersive experience of a large screen.

[0003] A flexible display screen is disclosed according to application number CN202420546225.6. This flexible display screen includes multiple functional film layers stacked sequentially and a buffer adhesive. The buffer adhesive fills the space between adjacent functional film layers, and is configured to bond adjacent functional film layers and buffer the bending direction of the functional film layers. Circuits are provided on each of the multiple functional film layers, and the extension direction of the circuits is perpendicular to the bending direction of the functional film layers. This flexible display screen has high reliability and flexibility, reduces the occurrence of circuit breaks within the functional film layers, extends service life, and saves costs.

[0004] Based on the above, in the existing technology, foldable flexible screens mainly achieve the foldable function of the device by integrating a high-precision hinge mechanism to balance portability and large screen experience. However, in actual use, when the flexible display screen is repeatedly bent, the corner area is prone to local stress concentration due to factors such as force concentration and sudden change in bending radius. This can not only cause microcracks, delamination or breakage of key structures such as flexible substrate, OLED light-emitting layer, and encapsulation layer, but may also lead to problems such as uneven display brightness, pixel failure or decreased touch sensitivity, affecting the reliability and service life of the screen. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an inward-folding flexible screen. In existing technologies, foldable flexible screens primarily achieve foldability by integrating high-precision hinge mechanisms to balance portability and a large-screen experience. However, in actual use, when the flexible display is repeatedly bent, the folded areas are prone to localized stress concentration due to factors such as concentrated force and abrupt changes in bending radius. This can lead to microcracks, delamination, or breakage in key structures such as the flexible substrate, OLED light-emitting layer, and encapsulation layer. It can also cause uneven display brightness, pixel failure, or decreased touch sensitivity, affecting the screen's reliability and lifespan.

[0006] The purpose and effect of this utility model's inward-folding flexible screen are achieved through the following specific technical means: An inward-folding flexible screen includes a protective film, a cover plate, a display panel, a functional film, a support plate, a shaping mechanism, and a supporting mechanism. The cover plate is fixed to the lower end face of the protective film. The display panel is fixed to the lower end face of the cover plate. The functional film is fixed to the lower end face of the display panel. The protective panel is fixed to the lower end face of the functional film. The support plate is fixed to the lower end face of the protective panel. The shaping mechanism is disposed on the lower end face of the support plate. The supporting mechanism is disposed on the lower end face of the support plate.

[0007] Furthermore, the shaping mechanism includes: a connecting and fixing mounting plate and connecting threaded holes; the connecting and fixing mounting plate is provided in multiple sets, and the multiple sets of connecting and fixing mounting plates are all fixedly connected to the lower end face of the support plate; the connecting threaded holes are provided in multiple sets, and the multiple sets of connecting threaded holes are respectively opened on the inner side of the multiple sets of connecting and fixing mounting plates.

[0008] Furthermore, the shaping mechanism also includes: mounting connection slots, mounting connection blocks, mounting connection holes, and mounting fastening screws; the mounting connection slots are provided in multiple sets, and the multiple sets of mounting connection slots are respectively opened on the inner side of the multiple sets of connecting and fixing mounting plates; the mounting connection blocks are provided in multiple sets, and the multiple sets of mounting connection blocks are respectively inserted into the inner side of the multiple sets of mounting connection slots; the mounting connection holes are provided in multiple sets, and the multiple sets of mounting connection holes are respectively opened on the inner side of the multiple sets of mounting connection blocks; the mounting fastening screws are provided in multiple sets, and the multiple sets of mounting fastening screws are respectively threaded into the inner side of the multiple sets of connecting threaded holes.

[0009] Furthermore, the shaping mechanism also includes a shaping arc plate; the shaping arc plate is hinged to the inner side of multiple sets of mounting and connecting blocks.

[0010] Furthermore, the support mechanism includes: a fixed connecting plate and a connecting fixing frame; there are two fixed connecting plates, both of which are fixedly connected to the lower end face of the support plate; there are two sets of connecting fixing frames, each of which is fixedly connected to the outer side of the two fixed connecting plates.

[0011] Furthermore, the support mechanism also includes: an arc-shaped transition plate; two arc-shaped transition plates are provided, and both arc-shaped transition plates are fixedly connected to the rear end face of the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves shaping of the flexible screen's corners through a shaping mechanism. After inserting the mounting connector into the mounting connector slot, a fastening screw passes through the mounting connector hole and is threaded into the connecting thread hole, thus completing the installation of the shaping arc plate. When the flexible screen is folded, the shaping arc plate effectively shapes the corners, making the bending trajectory smoother and more uniform, avoiding excessive bending in certain areas, significantly alleviating stress concentration in that area, thereby extending service life and reducing economic losses. The support mechanism limits the curvature of the flexible screen during folding. The connecting fixing frame is connected to the hinge; when the terminal folds, the hinge pushes the fixing connecting plate to fold the flexible screen. Simultaneously, the arc transition plate limits the bending curvature of the flexible screen during folding, ensuring deformation within a safe curvature range, further reducing mechanical stress on the internal functional layers, and improving the overall structural stability and durability. Through the synergistic effect of these mechanisms, not only is the corner shaping of the flexible screen achieved, but the dynamic curvature during folding is also effectively controlled, significantly extending the service life of the flexible screen and reducing economic losses.
