Polarized film for LCD
Liquid crystal displays (LCDs) are widely used in modern visual appliances such as smartphone touch screens or high definition television screens. The display consists of liquid crystals that are activated by an electric current. Depending on the activation state of the crystals, they block or allow polarized light to pass through. polarized film for LCD is used to increase the visibility of the image created on the LCD, by polarizing light so that it has a constant and precisely defined direction.
Iodine containing polarizing films are made by adsorbing iodine onto a stretched polyvinyl alcohol surface.
Do you need a polarizer?
Actually, polarizers are one of the few universally useful filters. They’re effective for both film and digital and unlike warming and other color correcting filters, they really can’t be digitally simulated. They can increase color saturation, reduce reflections and darken a blue sky. I’d say that if you own only one filter, it should probably be a polarizer. It’s the only filter I routinely carry as part of my general shooting kit.

Where to buy LCD polarized sheet?
3Dlens supplies thebest LCD polarizing sheet at the lowest price as a replacement to repair old LCD polarizer damage.
High contrast LCD polarizer sheet is best for TFT LCD polarizer repair and damage LCD polarizer replacement.
There LCD polarizer film will not fade under normal exposure to the light. Under room temperature and humidity, life will last for 10~20 years.
Basically, the LCD polarizer film structure is of 3 layers; polarizing membrane (PVA) and support layers (TAC) on both sides. Besides, there is an additional adhesive glue layer on one side.
Their polarizer film for the mobile LCD screen has a variety of sizes with a superior extinction ratio and high transmittance of polarized light in the range of 400~700nm.
They sell LCD polarizer film to many countries as the Philippines, Malaysia, Australia, UK, India, Brazil, Singapore, and so on.
These LCD polarizing sheets can be easily cut with scissors or a paper cutter.
