Description

A 360° privacy-protecting light-controlled membrane structure Technical Field

[0001] This utility model relates to the field of privacy light control film technology, specifically to a 360° privacy light control film structure. Background Technology

[0002] With the continuous development of electronic display technology, flexible screens, curved screens, and foldable screens are gradually gaining favor among manufacturers of electronic display devices such as mobile phones and tablets; at the same time, in order to increase the privacy and security of display screens, privacy protection is also a current research focus.

[0003] Light-control films typically employ an ultra-fine venetian blind structure. This structure is created by creating grooves in the light-transmitting film layer and filling them with light-blocking material, thereby reducing the visible range and achieving a sense of privacy and security.

[0004] As people pursue higher quality privacy protection, optical films with 360° privacy protection have gradually emerged.

[0005] Current 360° privacy light control films are made by orthogonally bonding two privacy structures. This process results in a thicker film (2 privacy layers + 2 substrate layers + 1 bonding layer), poor touch sensitivity, and a complex manufacturing process—cutting and orthogonally bonding, leading to low material utilization. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a 360° privacy-protecting light control film structure, which can reduce the thickness of the light control film, improve the user experience, improve touch sensitivity, and has a simple manufacturing process, which helps to improve production efficiency.

The first privacy layer and the second privacy layer are integrally formed on one side of the substrate layer or integrally formed on both sides of the substrate layer. The first privacy layer is provided with a first louver structure, and the second privacy layer is provided with a second louver structure. The first louver structure and the second louver structure are orthogonal.

[0009] Furthermore, the first privacy layer and the second privacy layer are integrally formed on one side of the substrate layer. The first privacy layer includes a first light-transmitting film, on which a plurality of first grooves are arranged side by side in the Y-axis direction. The plurality of first grooves are filled with a first light-blocking material to form a first venetian blind structure. The second privacy layer includes a second light-transmitting film, on which a plurality of second grooves are arranged side by side in the X-axis direction. The plurality of second grooves are filled with a second light-blocking material to form a second venetian blind structure.

[0010] Furthermore, the first privacy layer and the second privacy layer are integrally formed on both sides of the substrate layer. The first privacy layer includes a first light-transmitting film, on which a plurality of first grooves are arranged side by side in the X-axis direction. The plurality of first grooves are filled with a first light-blocking material to form a first venetian blind structure. The second privacy layer includes a second light-transmitting film, on which a plurality of second grooves are arranged side by side in the Y-axis direction. The plurality of second grooves are filled with a second light-blocking material to form a second venetian blind structure.

[0011] Furthermore, the height of the first and second light-shielding materials is 10-200 μm, the distance between two adjacent first light-shielding materials and two adjacent second light-shielding materials is 10-50 μm, the angle between the first and second light-shielding materials and the substrate layer MD direction is 0°-180°, and the angle between the first and second light-shielding materials is 45°-135°.

[0012] Furthermore, the thickness of the substrate layer is 10–50 μm, 50–100 μm, or 100–250 μm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a 360° privacy-protecting light control film structure, including a substrate layer, a first privacy layer and a second privacy layer. The first privacy layer and the second privacy layer are integrally formed on one side of the substrate layer or integrally formed on both sides of the substrate layer. This structure can greatly reduce the thickness of the light control film, improve touch sensitivity, thereby enhancing the user experience. Moreover, its manufacturing process is simple and helps to improve production efficiency. Attached Figure Description
