Abstract: An optical element and a method for manufacturing the optical element are described. The optical element includes a transparent substrate, an optical layer, and an adhesive layer. The optical layer is located on a surface of the transparent substrate. The optical layer has a first surface and a second surface, which are opposite to each other. The first surface is set with various diffracting optical structures. A refractive index of the optical layer is equal to or greater than 1.4. The adhesive layer is sandwiched between the surface of the transparent substrate and the second surface of the optical layer.

Abstract: A switchable projector module includes a holder, a projector, and a switchable diffuser. The holder includes a first connection tank and a second connection tank, in which the second connection tank is located at a side of the first connection tank. The second connection tank has a spilling glue trench. The projector is engaged with the first connection tank and is configured to project a pattern image onto the second connection tank. The switchable diffuser is engaged with the second connection tank. The switchable diffuser is configured to switch between a first mode and a second mode, so as not to diffuse the pattern image in the first mode and diffuse the pattern image in the second mode.
