Generally the more common types of polarizers There are several kinds of

( 1 ) Reflective
When the light is dipped into the glass surface, the reflected light will be partially polarized . OLED Display Module Continuous use of multi-layer glass reflection effect can be non- polarized light into linearly polarized light .

( 2 ) type of complex refractive
The two calcite crystal bonding , the incident light will be broken down into two polarized , known usually light and very light .

( 3 ) two color microcrystalline
Having dichroic absorption tiny crystals are regularly arranged on the transparent sheet , which is an artificial method of the first polarizing film made ​​.

( 4 ) -type polymer dichroism
Good use of translucent polymer film to be directed to the membrane molecules , and then adsorbed with a dichroic substance, this is the main method of the polarizing film produced today . Such an absorption-type polarizer is a film (Film) or a plate (Plate or Sheet) form,20x4 lcd therefore , commonly referred to as a polarizing film (Polarizing Film) or polarizing plate (Polarizing Plate or Sheet). English is more popular on another call is Polarizing Filter.
