A light valve module including a first shell, a second shell, a light valve, an elastic pad and a sealant is provided. The first shell has an opening. The second shell is assembled to the first shell. The first shell and the second shell form a containing space therebetween. The light valve is disposed in the containing space and is exposed by the opening. The elastic pad is disposed between the first shell and the second shell for sealing the containing space. The sealant is adhered at a periphery of the opening and the light valve for sealing the containing space. In addition, a projection device having the light valve module is also provided.

Projection device and light valve module thereof

A vehicular projection system including a projection apparatus, a beam splitting module, and two projection screens is provided. The projection apparatus provides at least one image light beam. The beam splitting module divides the image light beam into a first image light beam and a second image light beam. The two projection screens receive the first image light beam and the second image light beam respectively. Each of the first image light beam and the second image light beam respectively forms an image on one of the two projection screens corresponding thereto.

Vehicular projection system projecting on multiple screens

A lens module includes a lens, a cam and an actuator. The lens has two driven parts disposed at one side of the lens. The cam is disposed beside the lens and has a rotation shaft and two cam surfaces, and a portion of the cam is located between the two driven parts. The two cam surfaces have the same shape and are on opposite sides of the cam. The two cam surfaces are in contact with the two driven parts respectively. The actuator is coupled with the rotation shaft and adapted to rotate the cam.
