POLARIZERS

LCDs are constructed with three basic types of polarizer films: Transmissive, Reflective or Transflective. Front surface polarizers are always transmissive. Rear surface polarizers can be any of the three.

	Transmissive rear polarizers are used in low ambient applications that require backlighting, and allow maximum transmission of the backlight brightness. The image is not viewable when the backlight is not switched on.
	Reflective rear polarizers are used in applications with no backlight, either because of insufficient backlight power or because of high ambient light.
	Transflective rear polarizers combine transmissive and reflective polarizers, which means that the image can be viewed in high or low ambient light when the backlight is switched on.
