To eliminate LED hotspots and create uniform brightness across the display by scattering light through microstructures or embedded particles.
Diffuser sheets scatter light for uniformity, while brightness enhancement films (BEFs) collimate light to increase on-axis brightness; they're typically used together in optical stacks.
Polycarbonate, PET, or PMMA substrates with silica or acrylic diffusing particles, often coated with anti-static or hard coat layers.
