The Florida team has replaced the reflective polarizer and the bottom sheet linear polarizer with one NWGP. The 200 nm thick NWGP is made from a grating structure with a pitch of around 100 nm. It reflects incident visible backlight that is parallel to the metal wire grid, while transmitting light that is perpendicular to the grid. This means that the reflected backlight can be recycled to enhance the display brightness. |
