3M kirkkautta parantava kalvo

Display brightness and energy efficiency often suffer due to light loss in LCD backlight units. The 3M Brightness Enhancement Film 7100256548 addresses this by redirecting off-axis light toward the viewer, significantly improving on-screen luminance without increasing power consumption. This micro-prismatic optical film is engineered for high-performance displays, delivering up to 60% brightness gain while maintaining excellent light transmission and minimal haze.

Who is it for

This film is ideal for display manufacturers and integrators working with LCD backlight units, LED displays, mobile devices, and automotive displays. It suits engineers seeking to enhance visual performance, reduce energy usage, or achieve thinner display profiles without compromising brightness or viewing angles.
