A light source module including a light guide plate, a light-emitting assembly and an optical film is provided. The light guide plate has a first surface, a second surface opposite to the first surface, a first side surface, a second side surface opposite to the first side surface, and a light incident surface connecting the first surface, the second surface, the first side surface and the second side surface. The light-emitting assembly is disposed beside the light incident surface and is adapted to provide a light beam toward the light incident surface. The optical film is disposed on the second surface. The optical film has a light-emitting surface parallel to the second surface and away from the light guide plate. The light-emitting surface includes a first edge region adjacent to the first side surface, a second edge region adjacent to the second side surface, and a central region.

Light source module and display apparatus

A projection device including a turntable module and a projection module is provided. The turntable module includes a first turntable and a second turntable. The first turntable is disposed on a surface. The second turntable is disposed on the first turntable and connected to the first turntable, and rotates relative to the first turntable by revolving along a rotation axis. The projection module is disposed on the turntable module and fixed to the second turntable.

Projection device

An adjustment device for adjusting an angle of a dichroic mirror of a projector with respect to an optical engine base of the projector is disclosed. The dichroic mirror is pivotably mounted to the optical engine base. The adjustment device includes a link and an eccentric screw. The link has a first end and a second end. The first end is adapted to be fixedly mounted to the dichroic mirror. The second end has an opening. The eccentric screw is adapted to extend through the opening to be screwed to the optical engine base. The eccentric screw includes an eccentric section disposed within the opening. The eccentric section pushes the link such that the link drives the dichroic mirror to pivot with respect to the optical engine base upon rotating of the eccentric screw. A projector including the adjustment device is also disclosed.

Adjustment device and projector having the same

A filter housing structure adapted to a projector having a first encircled hook-and-loop fastening layer, a housing, a filtering layer, and a second encircled hook-and-loop fastening layer is provided. The first encircled hook-and-loop fastening layer is fixed on the casing of the projector and surrounds the openings arrayed on the casing. The housing has a central portion and a boundary portion. The central portion has a plurality of through holes thereon corresponding to the openings of the casing. The boundary portion surrounds the central portion and is corresponding to the first encircled hook-and-loop fastening layer. The filtering layer is assembled in the central portion and is disposed between the through holes and the openings for shielding the through holes. The second encircled hook-and-loop fastening layer is fixed on the boundary portion for fastening the housing to the first encircled hook-and-loop fastening layer.
