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： An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection.

A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure. A light distribution portion is disposed with respect to the slit to receive the light turned by said turning microstructure and transmitted out of the second side of the light injection portion and through said slit. At least one bridge is disposed between light injection portion and the light distribution portion. The bridge mechanically connects the light injection portion to the light distribution portion.

摘要： This disclosure provides systems, methods and apparatus for an electromechanical system. In one aspect, an electromechanical interferometric modulator system includes a substrate and a plurality of interferometric modulators (IMODs). At least two different IMOD types correspond to different reflected colors. Each IMOD has an optical stack, an absorber layer, a movable reflective layer, where the movable reflective layer has at least open and collapsed states, and an air gap defined between the movable reflective layer and the optical stack in the open state. The optical stacks define different optical path lengths for each of the different IMOD types by way of different transparent layer thickness and/or material, while the air gap has the same size when in the open state. The IMODs reflect different colors in the closed state and a common appearance in the open state. Use of two absorbers aids in defining the common appearance in the open state and can also improve color saturation.

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： A shielding material that can be arranged with respect to display elements to reduce potential damage or degraded performance caused by incident EM, such as UV and/or IR. The shielding material can be configured to be substantially transparent in visible light wavelengths. The shielding material can include inorganic materials, such as oxides including zinc oxide and titanium dioxide. Display elements can include a shielding material and an outer coating to reduce undesirable optical characteristics of an air/shielding material interface. The shielding material can be electrically conductive and function as a conductive layer in a microelectromechanical system (MEMS) device. In some embodiments, the shielding material can be disposed forward (closer to the viewer) of the electrodes of the display elements to prevent the high energy UV light from building up electrical charge in the electrodes. In some embodiments, the shielding material can also block certain wavelengths of light in the visible spectrum to darken the dark state of the display elements to improve the contrast ratio of the display.
