Metallized PET Film that looks bright on a sample card may still produce uneven illumination in a backlight. Reflector selection must follow the light source, spacing and optical stack.
As a Metallized Film Supplier, Cailong lists VPET-TZ reflective PET in matte silver and glossy silver types for polarizer composites and backlight reflection.
Place both candidates in the same display assembly. Map brightness across the viewing area and inspect from the required angles. Keep LED position, diffuser and reflector-to-source distance unchanged.
A glossy surface and a matte surface distribute reflected light differently. The preferred appearance of loose film does not establish which type gives the required screen uniformity.
Evaluate creases, mounting contact and local gaps on assembled samples. If a dark zone follows a deformation, correct that geometry before changing the finish.
Share the backlight layout, brightness map and mounting method with Cailong for VPET-TZ sample selection.
