A system and method for an optical component that masks non-active portions of a display and provides an electrical path for one or more display circuits. In one embodiment an optical device includes a substrate, a plurality of optical elements on the substrate, each optical element having an optical characteristic which changes in response to a voltage applied to the optical element, and a light-absorbing, electrically-conductive optical mask disposed on the substrate and offset from the plurality of optical elements, the optical mask electrically coupled to one or more of the optical elements to provide electrical paths for applying voltages to the optical elements. In another embodiment, a method of providing an electrical signal to optical elements of a display comprises electrically coupling an electrically-conductive light-absorbing mask to one or more optical elements, and applying a voltage to the mask to activate the one or more optical elements.

Device having a conductive light absorbing mask and method for fabricating same

In various embodiments described herein, a display device comprising a light collection film and a photovoltaic device disposed on an edge of the collection film. The collection film has a plurality of light-turning features for redirecting light between the front and back surface of the collection film and the photovoltaic device. In some embodiments, a light source is also disposed on an edge of the collection film and emits light which is turned by the light-turning features toward the display.

Simultaneous light collection and illumination on an active display

Tunable MEMS resonators having adjustable resonance frequency and capable of handling large signals are described. In one exemplary design, a tunable MEMS resonator includes (i) a first part having a cavity and a post and (ii) a second part mated to the first part and including a movable layer located under the post. Each part may be covered with a metal layer on the surface facing the other part. The movable plate may be mechanically moved by a DC voltage to vary the resonance frequency of the MEMS resonator. The cavity may have a rectangular or circular shape and may be empty or filled with a dielectric material. The post may be positioned in the middle of the cavity. The movable plate may be attached to the second part (i) via an anchor and operated as a cantilever or (ii) via two anchors and operated as a bridge.

MEMS varactors

An optical accelerometer and method of determining an acceleration are disclosed. In one aspect, an accelerometer includes a light source, a substrate, a light guide attached to a first side of the substrate and configured to redirect light from the light source through the substrate. The accelerometer also includes a light detector, a proof mass attached to a second side of the substrate via one or more springs, wherein the second side is opposite the first side and wherein motion of the proof mass alters a characteristic of the light from the light source reaching the light detector, and a processor configured to determine an acceleration based on the characteristic of the light reaching the light detector.

Display-integrated optical accelerometer

Embodiments includes methods and systems for updating display devices at a variable refresh rate. One embodiment includes a method of updating an image displayed on a display device. The method includes setting an indicator to a first state that indicates that image data has been received subsequent to a previous update of a display device and periodically updating at least a portion of the display device to display the image. The updating is deferred for at least one period when the indicator is in a state other than the first state. In another embodiment, updates of the display are substantially asynchronous and occur as the processor writes data to one or more shift registers. When a shift register is filled, for example, having received data for a row within the display, the data in the shift register is written to the display. Other embodiments include methods of manufacturing such devices.

System and method for providing a variable refresh rate of an interferometric modulator display

In one embodiment of the invention, a display is provided and includes a plurality of interferometric display elements. The display further includes at least one diffuser. Optical properties of the diffuser are selected to reduce color shift of the display when viewed from at least one angle.

Method and device for compensating for color shift as a function of angle of view

A package is made of a transparent substrate having an interferometric modulator and a back plate. A non-hermetic seal joins the back plate to the substrate to form a package, and a desiccant resides inside the package. A method of packaging an interferometric modulator includes providing a transparent substrate and manufacturing an interferometric modulator array on a backside of the substrate. A back plate includes a curved portion relative to the substrate. The curved portion is substantially throughout the back plate. The back plate is sealed to the backside of the substrate with a back seal in ambient conditions, thereby forming a package.

Method of making an electronic device with a curved backplate

A display with a photovoltaic (PV) cells integrated as the front side and/or back side of the display is disclosed. Ambient light may reach a PV cell situated behind a display through fully or partially transmissive features within the display. Display-generated light may also reach a PV cell behind a display. A transmissive PV material situated in front of a display may collect both ambient light as well as display-generated light.

Display with integrated photovoltaic device

Charge balanced display data writing methods use write and hold cycles of opposite polarity during selected frame update periods. The transitions between voltages of opposite polarity are sufficiently brief that the display elements do not change state. A release cycle may be provided to reduce the chance that a given display element will become stuck in an actuated state.

Method and system for writing data to MEMS display elements

This disclosure provides systems, methods and apparatus for manufacturing display devices having electronic components mounted within a display device package. In one aspect, the electronic component connects to the exterior of the display device through pads that run below a seal that holds a substrate and a backplate of the display device together. In another aspect the electronic components also connect to an electromechanical device within the display device, as well as connecting to pads that are external to the display device.

Backplate interconnect with integrated passives

The color reflected by an interferometric modulator may vary as a function of the angle of view. A range of colors are thus viewable by rotating the interferometric modulator relative to an observer. By placing a textured layer between an observer and an interferometric modulator, a pattern which includes the range of colors may be viewed by the observer, and the range of colors may thus be viewable from a single viewing angle.

Devices and methods for enhancing color shift of interferometric modulators

Methods and systems for packaging MEMS devices such as interferometric modulator arrays are disclosed. One embodiment of a MEMS device package structure includes a seal with a chemically reactant getter. Another embodiment of a MEMS device package comprises a primary seal with a getter, and a secondary seal proximate an outer periphery of the primary seal. Yet another embodiment of a MEMS device package comprises a getter positioned inside the MEMS device package and proximate an inner periphery of the package seal.

Method and system for packaging MEMS devices with glass seal

A package structure and 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 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.

Method and device for packaging a substrate

Charge balanced display data writing systems, apparatuses, and methods use write and hold cycles of opposite polarity during selected frame update periods. A release cycle may be provided to reduce the chance that a given display element will become stuck in an actuated state.
