Core Advantages

Advanced Process

Laser-dotting process with no screen-printing ink — eliminates aging, peeling, and panel yellowing for stable long-term performance.

Superior Optics

Light transmittance up to 88%–92% and luminance uniformity ≥ 90%. Soft, refined light with no dark/bright color deviation, no flicker, and no glare.

Free Material & Thickness Choice

Precisely customized to any thickness (2–12 mm) and any shape — rectangular, circular, arc, rounded corner, hole, groove, or irregular. Compatible with LED light boxes, display stands & cabinets, and non-standard equipment structures.

Weatherproof & Durable

Virgin optical base material resists high/low temperatures, moisture, and oxidation, with an indoor service life of more than 5 years.

Flexible Customization

Standard sizes, irregular shapes, arcs, and cutouts supported. Orders of any size are welcome — from single prototypes to mass production.

Compliance & Certification

RoHS, CE, FCC, ISO9001, ISO14001, EN62471 and other optical safety certifications available to meet export requirements.

Customization Notes

Shape & Size

Provide drawings or dimensions — custom cutting available for rectangular, circular, arc, hole, and irregular shapes.

Optical Simulation

Based on LED strip position and chip parameters, dot layout is simulation-optimized to guarantee uniform illumination across the whole panel.

Full Assembly Delivery

Can be delivered as a complete backlight assembly with diffuser plates, reflective film, and LED strips.

Documentation Support

Material reports and test certificates provided to support customs clearance and factory audits.

Usage & Installation Notes

⚠

Surface Protection

Each panel ships with PE protective film on both sides. Do not peel it off before installation to avoid scratches, dust adhesion, or fingerprints during handling and assembly — remove the film only after installation is complete.

⚠

Installation Environment

Suitable for dry indoor environments. Avoid prolonged exposure to high humidity, rain, strong corrosive agents, or intense direct sunlight, which can cause moisture deformation and accelerated aging.

⚠

Light Source Compatibility

Designed for side-lit (edge-lit) LED backlight configurations.

⚠

Assembly & Alignment

Ensure the LED strip sits flush and aligned with the light-entry edge of the plate — no tilting, gaps, or compression — to avoid optical defects such as dark edges, bright edges, or discontinuous light output.

⚠

Cleaning Method

Wipe the surface gently with a lint-free soft cloth. Do NOT use alcohol, thinner, or strong acid/alkali solvents, which may corrode or fog the surface and reduce light transmittance.

⚠

Intended Use

This is an indoor commercial backlight panel — not explosion-proof or outdoor-rated. Never use it in flammable/explosive environments or extreme industrial high/low-temperature scenarios.
