Description

Technical Field

[0001] This utility model specifically relates to the field of novel light guide plate technology, and more specifically to a novel light guide plate with uniform light distribution. Background Technology

[0002] In applications such as LCD displays and lighting, light guide plates, as core optical components, play a crucial role in transforming point or line light sources into uniform surface light sources. However, traditional light guide plates are limited by technological shortcomings and struggle to meet increasingly demanding quality requirements. In terms of dot matrix design, the single shape and density layout cannot adapt to the attenuation pattern of light propagating within the light guide plate, resulting in significant differences in light intensity between the edges and the center, leading to uneven light output issues such as bright spots and dark areas. Regarding optical coatings, the lack of efficient integrated design and poor synergy between the diffusion film and the brightness enhancement layer prevents the effective elimination of dot matrix projection shadows and hinders the full recovery of escaped light, resulting in significant light loss and insufficient light output uniformity.

[0003] Meanwhile, the structural design flaws are also quite prominent. The positioning accuracy between the light guide plate and surrounding components is low, and relative displacement can easily occur due to vibration and thermal expansion and contraction, which can disrupt the stability of light incidence and transmission. In the current context of stringent requirements for image quality uniformity in high-end displays and the pursuit of higher quality lighting environments in medical, precision manufacturing, and other lighting scenarios, traditional light guide plates have become a bottleneck restricting the upgrading of end products.

By installing four fixing brackets on the novel light guide plate, the uniformity and adaptability of light output of the novel light guide plate are improved, while the light efficiency and energy efficiency are also improved; thus solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A new type of light guide plate, which has fixed clamps connected to all four corners;

[0008] The novel light guide plate includes a light guide plate that is rectangular in shape. The edge area of ​​the light guide plate has large-sized, high-density circular dots, and the central area has small-sized, low-density diamond dots. A sealing and bonding ring with a rectangular ring is provided on the front side of the light guide plate. The sealing and bonding ring is used to connect with the nanoscale diffusion film on the front side of the light guide plate.

[0009] As a further technical solution of this utility model, the nanoscale diffusion film is rectangular in shape, and a second sealing and adhesive ring in the shape of a rectangular ring is provided on the front side.

[0010] As a further technical solution of this utility model, the microprism brightening layer is rectangular in shape, and a sealing and bonding ring three is provided on the front side in the shape of a rectangular ring. The sealing and bonding ring three is used to connect with the protective layer on the front side of the microprism brightening layer. The protective layer is rectangular in shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a gradient composite dot pattern, with circular and diamond-shaped dots, combined with optical simulation to optimize the layout and surface light intensity, thus solving the problem of uneven light output from the source of light transmission.

This effectively eliminates bright spots and dark areas, making it suitable for high-end displays and precision lighting scenarios.

[0016] 2. This utility model features a microprism brightening layer that recovers escaped light, increasing light utilization to over 90%.
