    New polarizer film to boost contrast of LCDs more than 10-fold

    A Japanese company called Zeon claims it has developed a film for the polarizing plates of LCD screens that boosts picture contrast by more than an order of magnitude. The company is already selling films for those plates to LCD TV makers like Samsung whose screens are based on vertical alignment technology. It produces films for OLED screens, too. Zeon's new, so-called phase difference film, however, is made from Cyclo Olefin Polymer, which makes it suitable for LCD TVs based on in-plane-switching (IPS) technology. Makers relying on IPS technology are Panasonic or Hitachi, for example. The new Zeon film inhibits the diffusion of light from the backlight. As a result, viewers get to see clearer pictures.
