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.

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： Techniques for providing LED-based backlighting in liquid crystal flat panel displays are disclosed. In one embodiment, the backlighting includes at least three color groups of light emitting diodes (LEDs) that are turned on successively for one frame of image. Liquid crystals (pixels) in an LCD are controlled in accordance with a display signal to transmit none, all or a determined amount of one or more of the colored lights from the three color groups of light emitting diodes in a cycle, resulting in an LCD with vivid colors and minimized tailing effects.

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： The present disclosure provides systems, methods and apparatus to illuminate displays. In one aspect, an illumination device with a light guide can include both faceted and holographic light turning features. The holographic light turning features can be provided between the facets. The facets can eject light out of the light guide. The holographic light turning features also can eject light out of the light guide, or can collimate the light so that it propagates more nearly parallel to the major surfaces of the light guide, or both eject and collimate light. The ejected light can be used to illuminate a display.

摘要： This disclosure provides systems, methods and apparatus, including reflective display elements that are illuminated using a light source that is situated behind the pixel elements. In one aspect, a back light guide is disposed behind the pixel elements and is configured to inject light through light-injection apertures between reflective pixel elements. The light travels through the light-injection apertures and into a front light guide. The front light guide comprises light turning features configured to turn the light propagating through the light-injection apertures so that the light is redirected onto the reflective pixel elements, thereby illuminating the reflective pixel elements.

摘要： One embodiment of the present invention provides a spatial light phase modulator, which can perform piecewise linear phase modulation of a light beam. This spatial light phase modulator includes an array of movable micromirrors and an array of actuators. Each actuator of the array of actuators is movably coupled to one micromirror of the array of movable micromirrors and can move the micromirror both vertically and rotationally. Additionally, the present invention provides an optical function generator that is a femtosecond pulse shaper. This optical function generator includes a diffraction grating that disperses an input pulse into a dispersed spectrum, a lens assembly to focus the dispersed spectrum onto a micromirror array, and the micromirror array to provide spatial filtering to the dispersed spectrum to provide the filtered spectrum.

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.
