ALCF-P is a louver film with a 60 degree viewing angle and is available with or without a matte hardcoat. ALCF-P is designed to be used on the outside of an LCD, and can go between the touch panel and the LCD.

ALCF-A and LCF are louver films with low birefringent polycarbonate substrates. This allows them to be used in the backlight of a liquid crystal display. A common use is to prevent night reflection onto glass surfaces in automobiles. ALCF-A has a 60 degree viewing angle. ALCF-A+ is a louver film combined with a reflective polarizer (DBEF).
