Technical Field

[0001] This utility model belongs to the field of diffusion plate technology, specifically an impact-resistant quantum dot diffusion plate. Background Technology

[0002] Quantum dot diffusers are advanced optical components that combine the light-emitting properties of quantum dots with light diffusion functions. They are widely used in display, lighting and other fields. Quantum dots are nanoscale semiconductors. By applying a certain electric field or light pressure to these nanoscale semiconductor materials, they will emit light of a specific frequency. Existing technologies often combine quantum dot technology with light diffusers to make quantum dot diffusers. However, existing diffusers are easily damaged by impacts during installation and removal, which affects the subsequent display effect and is not conducive to subsequent display operations. Therefore, we propose an impact-resistant quantum dot diffuser. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses an impact-resistant quantum dot diffuser plate. The diffuser plate body 100 has a protective frame 101 on its side. The diffuser plate body 100 includes a quantum dot film layer 102, a diffuser plate layer 103, and a protective layer 104. The diffuser plate layer 103 is fixedly connected to the rear side wall of the quantum dot film layer 102, and the protective layer 104 is fixedly connected to the outer walls of the quantum dot film layer 102 and the diffuser plate layer 103. The protective layer 104 facilitates the protection of the quantum dot film layer 102 and the diffuser plate layer 103, thereby increasing impact resistance.

[0021] In this embodiment: when blue light is emitted from the backlight, it enters the diffuser layer 103. The diffuser layer 103 scatters the light, thereby achieving a uniform distribution of light. The scattered light enters the quantum dot film layer 102. Some of the blue light is absorbed by the quantum dots and converted into red and green light, which mix with the unabsorbed blue light to form richer and purer colors. During installation, the protective frame 101 facilitates the protection of the diffuser body 100, preventing collisions during installation from directly impacting the diffuser body 100. This is beneficial for protecting the diffuser body 100 and improving the impact resistance of the device.

[0022] The quantum dot film 102 includes quantum dot particles 105 and a coating layer 106. The coating layer 106 is located on the outer wall of the quantum dot particles 105 and is made of thermosetting resin.

[0023] In this embodiment, the quantum dot particles 105 and the outer coating layer 106 surrounding the quantum dots constitute the quantum dot film layer 102. The coating layer 106 is formed by thermosetting resin to create a uniform protective film around the quantum dot particles 105, which improves the stability of the quantum dot particles 105 and protects them from external environmental factors such as moisture, oxygen and heat. The outer surface of the thermosetting resin layer is an uneven diffuse reflection layer formed by a matting agent, which can not only destroy the total internal reflection of the surface and enhance the scattering and transmission of light, but also increase the surface roughness of the board to a certain extent and improve its impact resistance.

[0024] The diffusion plate 103 includes a resin matrix 107 and scattering particles 108, wherein the scattering particles 108 are made of titanium dioxide.

[0025] In this embodiment: Titanium dioxide has a high refractive index of 2.5 and strong scattering efficiency. When the particle size is 100-300 nm, the haze can reach 85%. However, it is prone to agglomeration and requires surface modification such as treatment with silane coupling agent KH-570. Its resin matrix 107 is made of PMMA, which has a high light transmittance of 92% and good weather resistance. The diffuser layer 103 facilitates the scattering of light emitted from the backlight, which is beneficial for uniformly emitting the light source onto the quantum dot film layer 102 and improving the display effect.

[0026] The protective layer 104 includes a hardened coating 109 and an antistatic layer 110. The hardened coating 109 is made of UV-cured acrylate.

[0027] In this embodiment: the hardened coating 109 is made of UV-cured acrylic ester, with a hardness of 2H or higher, preventing scratches, and a light transmittance of ≥95%, facilitating light transmission for display. The antistatic layer 110 contains conductive agents such as carbon nanotubes, with a surface resistance ≤10 Ω·cm. 9 Ω prevents dust adsorption, improves weather resistance and wear resistance, and extends service life.

[0028] The protective frame 101 is provided with buffer pads 111 at each of its four corners, and the protective frame 101 is made of polystyrene.

[0029] In this embodiment: the buffer pads 111 are provided to protect the four corners of the protective frame 101, avoiding damage caused by bumps during handling and placement. The protective frame 101 is made of impact-resistant polystyrene material formed by combining styrene-based thermoplastic elastomers and polystyrene. This protective frame 101 has good toughness and impact resistance, and can effectively absorb and disperse external impact forces, protecting the overall structure of the diffuser plate body 100 and preventing it from being damaged by collisions.
