Description

Technical Field

[0001] This utility model relates to the technical field of optical films, and in particular to an antistatic brightness enhancement film. Background Technology

[0002] Brightness enhancement films are thin films or sheets specifically designed for TFT LCD backlight modules, with the core purpose of significantly improving the luminous efficiency of the entire backlight system. These films mainly include various types such as normal prism sheets, micro-lens films, and reflective polarizers.

[0003] However, most brightness enhancement films currently used in backlight modules employ a single, stacked structure. This design results in a relatively large overall thickness of the backlight film assembly, limiting the potential for further brightness enhancement. More seriously, this structure is also prone to generating Newton's rings, which negatively impacts display performance. Summary of the Invention

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an antistatic brightness enhancement film that uses a triangular structure to concentrate light and focuses the light through the rounded corners of the top wall of the triangle, thereby effectively improving the brightness.

[0006] To achieve the above objectives, this utility model proposes an antistatic brightening film, comprising a substrate layer, a base layer, and a structural layer, wherein the base layer is adhered to the lower surface of the substrate layer; the structural layer is disposed on the upper surface of the base layer; the substrate layer is a film made of PC or PET; the base layer is a stretched film; the structural layer is a UV adhesive coating, and each coating is bonded together with acrylic resin adhesive; the structural layer is a triangular coating, and the top wall of the structural layer has rounded corners.

[0007] The antistatic brightening film of this invention uses a triangular structure to concentrate light, and the rounded corners of the top wall of the triangle further focus the light, effectively improving the brightness.

[0008] In addition, the antistatic brightening film proposed in the application may also have the following additional technical features:

[0009] Specifically, the height of the structural layer is 12–27 μm, the inclination angle of the hypotenuse of the triangular side of the structural layer is 60°–90°, and the spacing between two adjacent structural layers is 15–70 μm.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0011] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] As shown in the figure: 10, substrate layer; 20, base layer; 30, structural layer. Detailed Implementation

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The antistatic brightening film of this utility model embodiment will be described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the antistatic brightening film of this utility model embodiment includes a substrate layer 10, a base layer 20, and a structural layer 30.

[0017] The base layer 20 is attached to the lower surface of the substrate layer 10, and the structural layer 30 is disposed on the upper surface of the base layer 20.

[0018] It should be noted that the substrate layer 10 is a film made of PC or PET. The base layer 20 is a stretched film, and the structural layer 30 is a UV adhesive coating, with each coating bonded together by acrylic resin adhesive.

[0019] In one embodiment of this utility model, such as Figure 1 As shown, the structural layer 30 is a triangular coating, and the top wall of the structural layer 30 has rounded corners.

[0020] It should be noted that the structural layer 30 is a triangular coating with rounded corners on the top wall. During the projection of the light source, the light is focused by the triangular structural layer 30 and the rounded corners at the top disperse the focused light, thereby improving the brightness.

[0021] In one embodiment of this utility model, such as Figure 1 As shown, the height of structural layer 30 is 12–27 μm, the inclination angle of the hypotenuse of the triangular side of structural layer 30 is 60°–90°, and the spacing between two adjacent structural layers 30 is 15–70 μm.

[0022] It should be noted that the height of the structural layer 30, the tilt angle of the inclined side, and the spacing between two adjacent structural layers 30 described in this embodiment need to be set according to actual needs and application scenarios.

[0023] Furthermore, the overall height of the antistatic brightening film is 30–150 μm, and the haze of the film is 5%–88%. The height and haze of the antistatic brightening film are set according to the actual situation and application scenario. In addition, antistatic agents are added to the raw materials during the film preparation process to enhance the overall antistatic performance of the film.

[0024] Specifically, the steps of applying the antistatic brightening film are as follows: light passes through the substrate layer 10 and the base layer 20, the light is focused in the structural layer 30, the light is gathered by the triangle of the structural layer 30, and then the light is concentrated by the rounded corner on the top wall of the triangle, thereby effectively enhancing the brightness.

[0025] In summary, the antistatic brightening film of this utility model uses a triangular structure to concentrate light and focuses the light through the rounded corners of the top wall of the triangle, effectively improving the brightness.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
