Screencasting display method, and electronic apparatus

Embodiments of this application provide a projection display method and an electronic device, and relate to the field of terminal technologies, to dynamically adjust, based on a quantity of source devices, a parameter of display data projected onto a destination device, so as to improve display smoothness and use experience of a user during projection. The method includes: A source device sends a projection instruction to a destination device, where the projection instruction is used to instruct to project a display interface of the source device onto the destination device for display. The source device receives a first broadcast sent by the destination device, where the first broadcast includes a quantity N of source devices that need to perform projection onto the destination device for display. The source device negotiates a first projection parameter with the destination device based on the quantity N of the source devices, where the first projection parameter includes one or more of a projection resolution, a transmission bit rate, or an encoding compression rate. The source device sends first display data to the destination device based on the first projection parameter.

MEMS deployment flexures

A flexure assembly can have a stage that is deployed to a desired position by attachment of the flexure assembly to a housing. For example, a frame can be configured to be held in position by one portion of the housing and a deployment pad can be configured to be held in position by another portion of the housing. A deployment flexure can be configured to facilitate positioning of the frame and the deployment pad out-of-plane with respect to one another. The deployment flexure and a motion control flexure can facilitate movement of the stage with respect to the housing. In this manner, the position of the stage and the preload of the stage are determined by the housing.
