AI Technical Summary
Traditional LED backlights, in pursuit of brightness uniformity and high optical efficiency, suffer from high power consumption, large thickness, and difficulty in achieving both low power consumption and ultra-thinness, especially in large-size, high-resolution display panels.
By employing a nano-scattering particle layer, combined with the precise design of a high-reflectivity layer and a light guide plate, and through the optimization of the particle size, concentration, and distribution of the nano-scattering particles, efficient forward scattering and directional control of light are achieved, reducing multiple scattering and absorption losses of light within the diffusion layer.
While reducing power consumption, it achieves high brightness uniformity and ultra-thinness, improves light energy utilization, and meets the requirements of modern display products for thinness and low power consumption.
