摘要： A white light generating organic electroluminescent device including an organic light emitting diode emitting a broad spectrum light including a component of each primary color. A multi-mode microcavity structure is positioned to cooperate with the diode defining an optical length of the microcavity structure to enhance the broad spectrum light and obtain multiple resonant peaks, one at each primary color. A plurality of filters are positioned to receive and adjust the multiple resonant peaks to provide substantially balanced multiple resonant peaks.

摘要： A MEMS device and method of making same is disclosed. In one embodiment, a micro-switch includes a base assembly comprising a movable structure bearing a contact pad. The base assembly is wafer-scale bonded to a lid assembly comprising an activator and a signal path. The movable structure moves within a sealed cavity formed during the bonding process. The signal path includes an input line and an output line separated by a gap, which prevents signals from propagating through the micro-switch when the switch is deactivated. In operation, a signal is launched into the signal path. When the micro-switch is activated, a force is established by the actuator, which pulls a portion of the movable structure upwards towards the gap in the signal path, until the contact pad bridges the gap between the input line and output line, allowing the signal to propagate through the micro-switch. Prior to bonding, the MEMS structures are annealed on a first wafer and the conductive traces and other metals are annealed on a second wafer to allow each wafer to be processed separately using different processes, e.g., different annealing temperatures.

摘要： A micro electro-mechanical systems device having variable capacitance is controllable over the full dynamic range and not subject to the “snap effect” common in the prior art. The device features an electrostatic driver (120) having a driver capacitor of fixed capacitance (121) in series with a second driver capacitor of variable capacitance (126). A MEMS variable capacitor (130) is controlled by applying an actuation voltage potential to the electrostatic driver (120). The electrostatic driver (120) and MEMS variable capacitor (130) are integrated in a single, monolithic device.
