Optical constructions are disclosed. A disclosed optical construction includes a reflective polarizer layer, and an optical film that is disposed on the reflective polarizer layer. The optical film has an optical haze that is not less than about 50%. Substantial portions of each two neighboring major surfaces in the optical construction are in physical contact with each other. The optical construction has an axial luminance gain that is not less than about 1.2.

Optical construction and display system incorporating same

An optical article includes an optical element, a low refractive index layer disposed on the optical element having an effective refractive index of 1.3 or less and a polymeric protective layer disposed on the low refractive index layer. The low refractive index layer includes a binder, a plurality of metal oxide particles dispersed in the binder, and a plurality of interconnected voids. The polymeric protective layer does not increase an effective refractive index of the optical article by greater than 10%.

This application describes a back-lit transmissive display including a transmissive display and a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first regions of nanovoided polymeric material and second regions of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.

Vacuum insulated glass units having layered pillars. The glass units include two glass panes and an edge seal between the glass panes with a substantial vacuum gap between them. A plurality of pillars are located between the glass panes as spacers to maintain the vacuum gap. The pillars have a sintered ceramic, alpha alumina, or zirconia body with a tapered sidewall and a functional layer on a surface of the body.
