Component Specifications

Definition
A precision-engineered interface component that facilitates the secure attachment and optical alignment of reflective sheets to light guide plates in LCD backlight units. It ensures optimal light redirection and minimal light leakage by maintaining precise positioning and contact between the reflective surface and light guide plate edges.
Working Principle
The reflective sheet interface operates by providing a mechanical and optical coupling between the reflective sheet and light guide plate. It uses precision alignment features (such as tabs, slots, or adhesive zones) to position the reflective sheet at the correct angle and distance to capture escaping light from the light guide plate edges and redirect it back into the plate, enhancing overall luminance efficiency and uniformity.
Materials
Typically made from engineered plastics (e.g., polycarbonate, PMMA, or PET with optical-grade surface finish) or composite materials with low thermal expansion and high dimensional stability. May include reflective coatings or embedded metallic elements for enhanced performance.
Technical Parameters
  • Thickness 0.5-2.0 mm
  • Reflectivity >95%
  • Surface Roughness <0.1 μm
  • Alignment Tolerance ±0.1 mm
  • Operating Temperature -20°C to 85°C
Standards
ISO 10110, DIN 3140
