The present disclosure provides an optical apparatus including a light source for generating light, where the light includes a first polarized light of a first phase. The optical apparatus further includes an adjustment structure for changing a propagation path of the light. The adjustment structure includes a polarization beam splitting structure for reflecting the first polarized light.

Optical device

The present disclosure provides an electronic device including a device body being maintained at a preset position relative to an eye of a user. The device body further includes: a display unit for emitting light corresponding to a display content; and a lens group having a side surface facing the display unit. The light emitted from the display unit is reflected by the side surface to be incident on the eye of the user.

Electronic device

A projection method, a projection apparatus and an electronic device are provided. The method may include: acquiring a target content to be projected in an electronic device; determining a projection parameter for the target content; adjusting a beam output mode of a light path changing module for projection beams of the target content based on the projection parameter; and based on the beam output mode, projecting, via the light path changing module, the projection beams of the target content into a first region of a projection carrier located away from the electronic device by a first distance, where the area of the first region varies with the beam output mode. With the projection method, the projection apparatus and the electronic device in the application, the area of the projection region can be adjusted easily, so that multiple users can use the electronic device to watch the projection conveniently.
