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： Disclosed are apparatus and methods for illuminating a display. In certain embodiments, the illumination apparatus includes a light guide that receives light from a light generator along an edge of the light guide and directs the received light via light extractor features (e.g., grooves) towards a display. The light guide includes at least two sets of light extractor features that are rotated with respect to each other so as to reduce a shadowing effect on the display when the display is viewed from within a specific range of viewing angles. In further embodiments, the spacing or orientation of each or one of the extractor feature sets may also be adjusted so that other visual artifacts, such as a Moiré effect, are reduced.

摘要： Methods of fabricating a static interferometric image device and static interferometric image device formed by the same are disclosed. In one embodiment, a method includes providing a substrate. A plurality of liquid layers are formed over the substrate 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. In some embodiments, the substrate includes pre-defined cavities, and the liquid layers are formed in the cavities. 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： A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.

摘要： Various embodiments of the invention include an interferometric optical modulator comprising a substrate layer and a light direction layer. Such an interferometric modulator may be integrated with a diffuser layer in a display device in a way that physically integrates the diffuser layer into the light direction layer in a way where the diff-user layer does not interact with light propagating within the light direction layer. As a result, most of the light propagating within the light direction layer does not penetrate into the diffuser which would inhibit performance of the display. In some embodiments, the interface between the diffuser layer and the light direction layer has a lower index of refraction than the light direction layer and the transparent substrate so that total internal reflection occurs at the interface.
