    摘要： A light guide device includes a light guide body and two or more pluralities of spaced-apart slits. The slits are formed by undercuts in the light guide body. Sidewalls of the slits form facets that redirect light impinging on the facets. In some embodiments, the light guide body is attached to a light source. The light source emits light that is injected into the light guide body and the slits redirect the light out of the light guide body and towards a desired target. In some embodiments, the target is a display and a first plurality of slits directs light from the light source across the light guide body and over the face of the display. A second plurality of slits then directs light out of the light guide body and towards the 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： 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.
