📊 Product Lineup

Five product families covering every display backlight application.

💻

Standard BEF

Single-layer prismatic film for laptop and monitor backlight. The standard replacement item in the refurbishment market.

Thickness: 125 / 150 / 155 / 215 µm
Prism Angle: 90° (±1°)
Pitch: 50 µm (±2µm)
Axial Gain: 1.57
Structure: Random micro-prism

DBEF (Dual BEF)

Reflective polarizer film that recycles light otherwise absorbed by the rear polarizer. Adds ~60% brightness gain on top of standard BEF.

Thickness: 155 / 215 µm

Best for: High-brightness panels, outdoor displays
🔬

Composite Films

Multi-in-one optical films that combine diffuser + prism layers. Thinner backlight, fewer assembly steps, better rigidity.

DOP: Diffuser + Prism (2-in-1)
MOP: Microlens + Prism (2-in-1)
POP: Prism + Prism (crossed, 2-in-1)
QPP: DBEF + Dual Prism (3-in-1)
📺

BEF for TV

Large-format prism film for TV backlight modules. Higher base thickness for structural stability in large panels.

Base Thickness: 225 µm
Prism Angle: 90° (±1°)
Structure: 1H3L (1 hard coat + 3 functional layers)
Axial Gain: 1.44
Back Surface: Matte finish
🚗

BEF for Car Display

Automotive-grade prism film with enhanced durability — ball-drop impact resistance, anti-blocking, and moiré reduction.

Size: 8-17" panels (or roll stock)
Thickness: 125 / 150 / 215 µm
Haze: 0% / 3% / 20% options
Axial Gain: 1.57

⚠️ Why Prism Film Needs Replacement

Common failure modes we see in refurbishment factories.

Yellowing & Haze — PET base and acrylic prisms degrade under prolonged heat from LED backlight, causing yellow tint and brightness loss
Scratches & Scuffing — Surface damage during disassembly or previous repair attempts, visible as bright lines when backlight is on
Liquid Damage Spots — Moisture ingress creates localized dark patches or prism delamination
Mixed-source Inconsistency — Using sheets from different suppliers in the same backlight causes uneven brightness and color shifts
