摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide includes a light turning film (128) over an optically transmissive supporting layer (129). In some implementations, the light turning film may be formed of a material deposited in the liquid state. In some implementations, the light turning film may be formed of a photodefinable material, which may be glass, such a spin-on glass, or may be a polymer. In some other implementations, the glass is not photodefinable. The light turning film may have indentations (131) that define light turning features and a protective layer may be formed over those indentations. The protective layer may also be formed of a glass material, such as spin-on glass. The light turning features in the light guide film may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, a passivation layer is attached to the light guide of an illumination device. The passivation layer may be an optically transparent moisture barrier and may have a thickness and refractive index which allows it to function as an anti-reflective coating. The passivation layer may protect moisture-sensitive underlying features, such as metallized light turning features that may be present in the light guide. The light turning features may be configured to redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus for a projected capacitive touch (PCT) sensor that may include thin sensor electrodes coated with additional layers to form an optical cavity that reinforces a wavelength range or color of incident light. The sensor electrodes (907a, 907b) and a cover glass border and/or decorations (1305) may be fabricated simultaneously. In some implementations, the thickness of the optical cavity will be selected such that the "color" of reflected light is black. The sensor electrodes (907a, 907b) may not be noticeable to a human observer. However, in some other implementations, the thickness of the optical cavity may be selected such that the sensor electrodes (907a, 907b) and/or the decorative portions (1305) will have another color. Routing wires (1120a) of the touch sensor may be shielded by a grounded conductive layer in the border.

In one embodiment, a method includes providing a substrate (1000). A plurality of liquid layers (1062a- 1062c) are formed over the substrate (1000) by an inkjet process such that the layers are lateral to one another. The liquid layers contain a solidifiable material or particles. Then, the plurality of liquid layers are solidified to form a plurality of solid layers ( 1064a- 1064c). In some embodiments, the substrate includes pre-defined cavities (1020), and the liquid layers are formed in the cavities (1020). In other embodiments, the substrate includes a substantially planar, stepped, or continuously transitioning surface, and the liquid layers are formed on the surface. The inkjet process provides optical fillers or spacers for defining interferometric gaps between absorbers and reflectors in the display device, based at least partially on an image that the display device is designed to display.

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a light input edge into which light is injected and transverse edges transverse to the light input edge. The transverse edges are smooth and act as specular reflectors. The light input edge is rough and provides a diffusive interface. The light emitters are adjacent and centered along the light input edge, with the pitch of the light emitters being about ?L, where ΔL is the distance between the transverse edges divided by the number of light emitters. The diffusive light input edge can diffuse light entering into the light guide, and the transverse edges can reflect light with a low level of artifacts and the reflections also act as virtual light sources to facilitate a highly uniform distribution of light within the light guide. The light guide can be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light can be applied to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus for providing illumination by using a light guide to distribute light. In one aspect, the light guide has a surface, such as an edge, into which light is injected. The surface is treated to create a diffusive interface with a light source. For example, the surface may be subjected to abrasion to form a frosted surface that acts as the diffusive interface, or a diffusive structure may be attached to the edge, with the attached diffusive structure functioning as the diffusive interface. The diffusive interface diffuses light entering into the light guide, and can thereby increase the uniformity of light propagating within the light guide. The light guide may be provided with light turning features that redirect light out of the light guide. In some implementations, the redirected light may be applied to illuminate a display.
