To uniformly distribute light from edge-mounted LEDs across the entire surface of an LCD panel, eliminating bright spots and ensuring consistent brightness for display visibility.
PMMA offers excellent optical clarity (over 92% light transmittance), good UV resistance, ease of precision molding, and cost-effectiveness, making it ideal for high-quality light diffusion.
Through micro-optical patterns (dots or grooves) on its surface that scatter light. The pattern density is carefully designed to increase with distance from the LED source, compensating for natural light attenuation to maintain uniformity.
