摘要： This disclosure provides systems methods and apparatus for calibrating and controlling the actuation of an analog interferometric modulator. In one aspect an electrode of a movable layer of the analog interferometric modulator may include a part for receiving a drive voltage and an electrically isolated part. A voltage may be sensed from the electrically isolated part and used to determine the position of the movable layer and/or provide feedback to the drive voltage.

摘要： This disclosure provides systems methods and devices for actuating charging and calibrating the charge on a movable electrode in an interferometric device. The interferometric device (1000) can include a first electrode (1002) a second electrode (1010) spaced apart from the first electrode by a gap at least one electrical contact (2132) and an electrically neutral movable third electrode (1006) disposed between the first electrode and the second electrode. The third electrode can be charged by applying a charging actuation voltage across the first electrode and the second electrode to produce an electric field in the gap. Under the electric field the electrically neutral third electrode (1006) can move towards the first electrode from a first position to a second position where it connects with the electrical contact (2132). Once in contact with the electrical contact an electric charge on the third electrode can be changed when the third electrode is in the second position. When a mechanical restorative force on the third electrode exceeds the force of the electric field on the third electrode the third electrode moves to a third position.

摘要： Interferometric modulators may include a movable layer including both permanently anchored and programmable hinges. Unactuated programmable hinges may exert little or no force on the movable layer. When actuated, programmable hinges may exert a mechanical force on the movable layer in a direction approximately opposite to the direction of force exerted by the permanently anchored hinges. By increasing a voltage between the programmable hinges and an electrode, a progressive number of programmable hinges may be engaged. The mechanical force exerted on the movable layer by these hinges may change the relative position of the movable layer within an IMOD device.
摘要翻译：干涉式调制器可以包括可移动层，包括永久锚定和可编程的铰链。未激活的可编程铰链可能在可动层上施加很少或不施加力。当被致动时，可编程的铰链可以在与永久锚定的铰链施加的力的方向大致相反的方向上在可动层上施加机械力。通过增加可编程铰链和电极之间的电压，可以接合渐进数量的可编程铰链。通过这些铰链施加在可移动层上的机械力可以改变可移动层在IMOD装置内的相对位置。

摘要： Systems and methods for manufacturing and packaging electronic devices with light absorptive thin film stacks are provided. In one embodiment, a light is applied to a light absorptive thin film stack disposed between a substrate and a backplate to seal the substrate to the backplate. In another embodiment, the light absorptive thin film stack includes a plurality of thin film layers. In yet another embodiment, the light absorptive thin film stack includes a spacer layer over a reflective layer and an absorber layer over the spacer layer. In still another embodiment, the light absorptive thin film stack is less than 200 nanometers thick. In yet a further embodiment, a light absorptive thin film stack is used to seal a substrate having glass, plastic, metal, or silicon to a backplate having glass, plastic, metal, or silicon. Thus, the light absorptive thin film stack is used to seal similar or dissimilar materials through a bonding process.

摘要： This disclosure provides systems, methods and apparatus for driving three- terminal electromechanical systems (EMS) devices. The driving systems and methods described herein include a switched capacitor charge injection circuit (1530) that is configured to isolate a single EMS device and transfer a desired amount of charge to the isolated device such that the device can be actuated to produce a desired optical, electrical or mechanical effect. The charge injection circuit includes an operational amplifier (1315) and is connected such that the EMS device is placed in the feedback path of the operational amplifier (1315).

摘要： This disclosure provides systems, methods and apparatus related to an electromechanical display device. In one aspect, an analog interferometric modulator includes a display pixel having a movable reflector, and a movable absorbing layer. The movable absorbing layer is positionable at a variable first distance from an electrode that is substantially transparent over a visible wavelength spectrum. The movable reflector is positionable at a variable second distance from the movable absorbing layer. Changing the first distance and the second distance changes a characteristic of light reflected from the display element.
