In most LED modules, the Louver is the final installed component. This louver structure, fixed after the basic assembly of the module, is critical for measuring the off-state brightness performance. 

Less direct sunlight reflection correlates with higher overall contrast. Outdoor installations are exposed to sunlight for most of the day, necessitating rigorous louver design to ensure optimal display performance. The design process requires balancing contrast and viewing angles

LED display louver : improve performance and life.

• Full Protection
• The mask can protect LED lamp beads from dust, water, and other debris as a bodyguard of your display.
• Anti-Glare Design
• Special coatings greatly reduce on-screen reflections, making it easy to enjoy in bright outdoor conditions.
• Weather Resistance
• Constructed from waterproof and protective materials, the mask allows users to use their display in outdoor conditions ranging from heavy rain to bright sunshine.

Enhanced Visual Quality

 A matte surface scatters ambient light via diffuse reflection, resulting in a darker off-state and improved contrast uniformity across viewing angles. In contrast, a polished coating appears dimmer at the light incident angle, theoretically offering higher contrast, but causes severe glare at reflection angles, impairing side-angle viewing

Matte surfaces on louvers are typically achieved through coating processes. Most manufacturers apply anti-reflective, UV-resistant black paint to minimize light reflection
