Thickness directly impacts appearance, brightness uniformity, structure, and cost. Here’s how to pick correctly:
- 30–60mm (Ultra-Slim)
Best for indoor wall-mounted displays, small-to-medium sizes, and limited-depth spaces. Works with edge-lit LEDs for a sleek modern look. Ideal for retail walls, brand 形象墙,and reception areas.
- 80–100mm (Standard)
The most versatile choice for most retail and exhibition projects. Balances slim profile and sufficient light mixing space. Supports both edge-lit and backlit systems with stable brightness.
- 120mm+ (Heavy-Duty)
For large-format lightboxes, freestanding towers, double-sided displays, and outdoor use. Improves wind resistance, structural rigidity, and light uniformity for big surfaces.
