PROBLEM TO BE SOLVED: To provide a display device where mechanical components in a device, such as a microelectromechanical device, and/or in an interferometric modulator are configured to be insusceptible to damage.SOLUTION: A packaging system for an electronic device includes one or more spacers 730 that prevent or reduce damage to the electronic device arising from contact between the electronic device and a backplate 750. In addition, a packaged electronic device comprising spacers is thinner than a comparable electronic device manufactured without spacers.

PROBLEM TO BE SOLVED: To provide a system and a method of illuminating interferometric modulators using backlighting. SOLUTION: An interferometric modulator array device with backlighting is disclosed. The interferometric modulator array device includes a plurality of interferometric modulator elements, wherein each of the interferometric modulator elements includes an optical cavity. The interferometric modulator array includes an optical aperture region, and at least one reflecting element is positioned so as to receive light passing through the optical aperture region and reflect at least a part of the received light to the cavities of the interferometric modulator elements. In some embodiments, the interferometric modulator elements may be separated from each other such that an optical aperture region is formed between the plurality of adjacent interferometric modulator elements.

PROBLEM TO BE SOLVED: To provide a display device comprising an array of addressable light-modulating elements.SOLUTION: A spatial light modulator 40 comprises an integrated passive optical compensation structure 41, or a passive optical compensation structure 41 located on the opposite side of the light-modulating elements 44 from a transparent substrate 42. The individually addressable light-modulating elements 44 are configured to modulate light transmitted through or reflected from the transparent substrate 42. Methods for making the spatial light modulators 40 involve fabricating a passive optical compensation structure 41 over a substrate, and fabricating a plurality of individually addressable light-modulating elements 44 over the passive optical compensation structure 41. The passive optical compensation structure 41 may include one or more of a supplemental frontlighting source, a diffuser, a black mask, a diffractive optical element, a color filter, an anti-reflective layer, a structure that scatters light, a microlens array, and a holographic film.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a device for packaging a substrate. SOLUTION: There is provided a package structure and a method of packaging for an interferometric modulator. A thin film material is deposited over an interferometric modulator and transparent substrate to encapsulate the interferometric modulator. A gap or a cavity between the interferometric modulator and the thin film provides a space in which mechanical parts of the interferometric modulator may move. The gap is created by removal of a sacrificial layer that is deposited over the interferometric modulator. COPYRIGHT: (C)2011,JPO&INPIT
