摘要： In various embodiments described herein, a display device includes a front illumination device that comprises a light guide disposed forward of an array of display elements, such as an array of interferometric modulators, to distribute light across the array of display elements. The light guide panel may include a turning layer to deliver uniform illumination from a light source to the array of display elements. For many portable display applications, the light guide panel comprises the substrate used in fabricating the display elements. The light guide panel may include additional films as well. The light guide panel, for example, may include a diffuser and/or an optical isolation layer to further enhance the optical imaging characteristics of the 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： A microelectromechanical systems (MEMS) display element may include a photovoltaic structure configured to generate electric energy from incident light. In one embodiment, the display element includes a first layer that is at least partially transmissive of light, a second layer that is at least partially reflective of light, and a photovoltaic element that is formed on the first layer or the second layer or formed between the first layer and the second layer. The second layer is spaced from the first layer and is selectably movable between a first position in which the display element has a first reflectivity and a second position in which the display element has a second reflectivity. The first reflectivity is greater than the second reflectivity. The photovoltaic element is at least partially absorptive of light and is configured to convert a portion of the absorbed light into electric energy, at least when the second layer is in the second position.

摘要： Various embodiments of the present invention relate to enhancing the brightness of displays that employ illumination systems. In some embodiments, the illumination systems include light guides, diffractive microstructure, and light-turning features. The diffractive microstructure may be configured to receive ambient light at a first angle and produce diffracted light at a second angle greater than the first angle and greater than the critical angle for of light guide. The light is thereby guided within the light guide. The light-turning features may be configured to turn the light guided within the light guide out of a light guide and onto, for example, a spatial light modulator at near normal incidence.
