Polarizer

Polarizer (Top) : Light is horizontally polarized at the top polarizer. The function of the polarizer is to improve color and definition, making it possible to see the screens of LCDs. If polarizers were removed from LCDs, it would be impossible to recognize letters or graphics. When two polarizing films are placed one on the top of the other in parallel, the screen of the LCD will be at its brightest. However, when placed on the top of and perpendicular to each other, the screen will look as though it is black. Hence, the optical characteristics of LCDs, such as brightness and contrast, are greatly influenced by the properties of polarizing films.

Polarizer (Bottom) : Polarizer is made by stretching a plastic-like material to lengthen its fibers, then dipping the material in iodine to further lengthen and organize the material’s fibers into a grid of darkened parallel lines that are invisible to the human eye. This is like a filter that only allows light waves in a vertical orientation to pass through, and rest of the light waves are blocked off.

Prism sheet

Prism Sheet : A prism sheet is provided on the upper surface of the light guide plate of the liquid crystal display. The prism sheet has small, angled ridges on its front-facing surface that recycle off-axis light until it is emitted at the optimal viewing angle. The light waves either exit at the brightest angle to the viewer, or they are sent through the back lighting layers again until they exit correctly.

Diffuser sheet

Diffuser Sheet : A diffuser sheet is designed to break up and distribute light evenly to give the soft light. The diffuser sheet spreads the light evenly across the screen dimensions making a solid, evenly lit square and reduces LED hot-spots.

Reflector sheet

Reflector Sheet : A reflector sheet provides LCD backlight recycling. It is often called DBEF (dual brightness enhancement film). DBEF increases on-axis luminance and thus more light is available to be transmitted through the LCD. Typically, one BEF can increase brightness by 40%-60%. In some applications, two BEFs are used for enhanced brightness transmittance.
