摘要： According to examples, a phase plate may include a transparent substrate and a photopolymer layer attached to the transparent substrate. The photopolymer layer may adjust a backlight via a phase adjustment and focusing. The phase plate may focus a plurality of red, green, and blue components of the backlight onto respective red, green, and blue subpixels of a thin-film-transistor (TFT) layer deposited thereon. A distance between the photopolymer layer of the phase plate and the plurality of red, green, and blue subpixels of the thin-film-transistor (TFT) layer may be in a range from about 200 μm to about 500 μm. In some examples, the phase plate may be part of a liquid crystal display (LCD) apparatus along with a red, green, blue (RGB) laser to provide backlight; a grating light guide to transmit the backlight; and a liquid crystal display (LCD) layer on the thin-film-transistor (TFT) layer.

摘要： Systems, articles, and methods that integrate photopolymer film with eyeglass lenses are described. One or more hologram(s) may be recorded into/onto the photopolymer film to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lens around the photopolymer film; sandwiching photopolymer film in between two portions of a lens; applying photopolymer film to a concave surface of a lens; and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens. Respective lenses manufactured/adapted by each of these processes are also described.
