Light Guide Plate Products

A Light Guide Plate (LGP) is a core precision optical component widely used in display backlight systems and flat lighting equipment. Manufactured from high-purity optical-grade PMMA acrylic or PC material, this ultra-transparent panel adopts advanced microstructure dot etching and laser engraving technology. Based on the principle of total internal reflection, it efficiently converts point-type and linear LED light sources into uniform, soft surface light. Eliminating hot spots, dark zones and uneven brightness, it serves as the key guarantee for ultra-thin, high-uniformity and high-brightness backlight display, extensively applied in LCD panels, Mini LED backlight modules, indoor panel lights, advertising light boxes, vehicle displays and industrial terminal screens.

The core advantage of the light guide plate lies in its professional optical conversion capability. Traditional direct-lit lighting causes concentrated light sources, glaring local brightness and poor overall uniformity. This LGP precisely controls light propagation path through scientifically arranged micro dot matrix. Light entering from the edge is continuously reflected, refracted and diffused inside the plate, achieving consistent luminous output across the entire surface. With ultra-high light transmittance and low haze design, it maximizes light utilization efficiency while maintaining soft and delicate light quality, effectively improving screen clarity and visual comfort.

In terms of material and craftsmanship, our LGP adopts high-purity imported optical raw materials with excellent light transmission performance and no impurity spots. The precision laser dot pattern design features gradual density distribution, reasonably matching light attenuation rules during transmission. It perfectly solves the edge-dark and center-bright common problems of ordinary guide plates, realizing full-screen zero-dark-area lighting effect. The smooth and flat plate surface ensures perfect fitting with diffuser films, reflective films and optical accessories, avoiding light distortion and scattering loss caused by assembly gaps.

Featuring outstanding physical stability and durability, the light guide plate delivers excellent anti-yellowing, anti-aging and high-temperature resistance performance. It maintains stable optical transmittance and structural flatness under long-term light irradiation and high-low temperature alternating environments, preventing brightness decay, color shift and plate deformation. The material possesses low thermal expansion coefficient and strong dimensional stability, adapting to long-term continuous operation of display devices and lighting fixtures, greatly reducing product failure rate and after-sales maintenance cost.

In terms of structural advantages, the ultra-thin and lightweight design perfectly fits the thinning trend of modern electronic equipment. Compared with traditional lighting structures, the edge-lit LGP solution saves more space and reduces overall product weight. With high light energy utilization rate, it effectively reduces power consumption and heat generation, achieving energy-saving and efficient lighting. The product supports customized size, thickness and dot pattern distribution, meeting personalized demands of different display specifications and lighting scenarios.
