An LCD device with 3D and 2D sections. The device includes an LCD panel, a light guide with a backlight, and an embedded 3D-2D film stack positioned between the LCD panel and the light guide. The 3D and 2D sections provide for simultaneously viewing visual content in 3D and 2D formats. The device can also include a frame providing a barrier between the 3D and 2D sections and can include other features to enhance the display.

Embedded stereoscopic 3D display and 2D display film stack

A photon emitting device comprises a plurality of solid state radiation sources to generate radiation. The solid state radiation sources can be disposed in an array pattern. Optical concentrators, arranged in a corresponding array pattern, receive radiation from corresponding solid state radiation sources. The concentrated radiation is received by a plurality of optical waveguides, also arranged in a corresponding array pattern. Each optical waveguide includes a first end to receive the radiation and a second end to output the radiation. A support structure is provided to stabilize the plurality of optical waveguides between the first and second ends. The photon emitting device can provide a replacement for a discharge lamp device in various applications including road illumination, spot lighting, back lighting, image projection and radiation activated curing.

Solid state light device

A continuous method for making porous foam and the foam articles are described. The method allows for tailoring the porosity of the foam by controlling process variables including draw rate and blowing agent concentration. A method for co-extruding the foams with other materials is also described.

Breathable polymer foams

A continuous method for making foams having uniform and/or small cell sizes and articles made with these foams are described. The method allows for adjusting or controlling cell size and cell size distribution by controlling temperature and/or blowing agent concentration. The foams feature small and/or uniform cell sizes and may be comprised of amorphous thermoplastic polymers, pressure sensitive adhesive compositions, and immiscible thermoplastic polymer compositions. A method for coextruding the foams is also described.

Uniform small cell foams and a continuous process for making same

The invention discloses reduced density foams and methods of making the foams by applying or creating a nonfoaming barrier layer on a foamable layer, which barrier layer inhibits the escape of fugitive gases during the foaming process.
