  • Patent number: 9864207
    Abstract: Polarizing beam splitter is disclosed. The polarizing beam splitter includes a first polymeric prism, a second polymeric prism, a reflective polarizer that is disposed between and adhered to a hypotenuse of each of the first and second polymeric prisms, and a hardcoat that is disposed on each of the first and second polymeric prisms. The polarizing beam splitter includes an input major surface and an output major surface. At least one of the input and output major surfaces has a pencil hardness of at least 3H. The polarizing beam splitter has a low birefringence such that when polarized light having a first polarization state enters the optical element from the input major surface and travels through at least 2 mm of the polarizing beam splitter and exits the polarizing beam splitter from the output major surface, at least 95% of light exiting the polarizing beam splitter is polarized has the first polarization state.

  • Publication number: 20130235515
    Abstract: An electronic display (100) is provided that includes a display panel (106) having an image—forming region, a substantially clear photocured bonding layer (104) which is the reaction product of a first photocurable resin system disposed upon the image—forming region, an obscuring layer (108) in proximity to at least a portion of the substantially clear photocurable bonding layer, and a substantially transparent outer panel (106) in contact with at least a portion of the obscuring layer. The bonding layer (104) is disposed partially beneath the obscuring layer (108). The obscuring layer has an average light transmission of less than about 5% in the wavelength range of 420 nm to 700 nm and a light transmission of greater than about 5% in the wavelength range of 300 to 400 nm. Also provided is a method for making the electronic display.
