At present, Disea's main polarisation suppliers are Chimei, Sunnypol and Nitto.
Some of our high-brightness displays, customers need to be visible in the outdoor sunlight, the problem comes, because of the harsh outdoor sunlight, the naked eye will be very serious glare when looking directly at the display, more people are willing to wear sunglasses to view the content on the display. The sunglasses themselves are a type of glass with a polarising layer, which will interfere with the polarising layer of the LCD, and the screen will be seen as a mass of colour, as shown in the picture.
We have a solution to this situation, which is to use a special polarising film with an internal protective film that is both circularly polarised and can convert the polarised light from the LCD into a circularly polarised state, allowing it to be seen under sunglasses, i.e. Sunglass Free.
