Micro-prismatic brightness enhancement films that redirect scattered light toward the viewer. Boost front-of-screen brightness by 40-60% without increasing LED power. Standard BEF, DBEF, and composite films for laptop, monitor, TV, and automotive displays.
Five product families covering every display backlight application.
Single-layer prismatic film for laptop and monitor backlight. The standard replacement item in the refurbishment market.
Reflective polarizer film that recycles light otherwise absorbed by the rear polarizer. Adds ~60% brightness gain on top of standard BEF.
Multi-in-one optical films that combine diffuser + prism layers. Thinner backlight, fewer assembly steps, better rigidity.
Large-format prism film for TV backlight modules. Higher base thickness for structural stability in large panels.
Automotive-grade prism film with enhanced durability — ball-drop impact resistance, anti-blocking, and moiré reduction.
Our #1 category. Pre-cut prism sheets for the most frequently refurbished laptop screens. Standard thickness 155µm / 215µm, prism angle matched to original panel orientation. Bulk pricing available for volume orders.
