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 over an optically transmissive supporting layer. The light turning film may be formed of a material deposited in the liquid state. 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 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, for example, 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 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 ΔL, where ΔL is the distance between the transverse edges divided by the number of light emitters. 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.

摘要： This disclosure provides systems, methods and apparatus related to an illumination system for a display device. In one aspect, the illumination system includes a light guide having a view region, which directly overlies display elements of a display, and a ledge region between the view region and a light source that injects light into the light guide. The ledge region is coated with an at least partially non-transmissive layer. The layer can be at least partially absorptive and/or at least partially reflective. In some implementations, the layer can include microstructures configured to turn steep-angle light such that it is redirected across the light guide at a shallower angle. In some implementations, the boundary between the ledge region and the view region of the light guide can have a nonlinear shape.

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 and a cover glass border and/or decorations 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 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 and/or the decorative portions will have another color. Routing wires of the touch sensor may be shielded by a grounded conductive layer in the border.

摘要： The invention provides a new process for patterning TPE membranes for use in the design and fabrication of 3D microfluidic devices. The process involves patterning a TPE material without permitting the highest features of the mold to come into contact with the counter-plate, whereby adhesion between the TPE and the mold or counter-plate during demolding results directly in removal of the excess layer from the TPE membrane to produce well formed micrometric-sized open-through holes in the TPE membrane. The process permits rapid, reliable and efficient patterning of densely packed and arbitrarily placed micrometric open-through holes and channels of high aspect-ratio and any shape or wall profile in thin TPE membranes.
