摘要： Conventional optical lens assembly typically require a capping window, which is expensive, to protect the optical sensor. Also, each conventional optical lens assembly is discretely assembled, and thus incurs additional costs. To address these and other disadvantages, it is proposed to assemble a plurality of imaging sensors, a plurality of spacers, and a plurality of lenses at a panel. The resulting lens assembly array can be individualized into separate lens assemblies.

摘要： Microelectromechanical system (MEMS) devices, methods of operating the MEMS device, and methods of manufacturing the MEMS device are disclosed. In some embodiments, the MEMS device includes a glass substrate; an electrode on the glass substrate; a hinge mechanically coupled to the electrode; a membrane mirror mechanically coupled to the hinge; a TFT on the glass substrate and electrically coupled to the electrode; and a control circuit comprising: a multiplexer configured to turn on or turn off the TFT; and a drive source configured to provide a drive signal for charging the electrode through the TFT. An amplitude of the drive signal corresponds to an amount of charge, and the amount of charge generates an electrostatic force for actuating the hinge and a portion of the membrane mirror mechanically coupled to the hinge. In some embodiments, the MEMS devices comprise a charge transfer circuit for providing the amount of charge.
