1. A light projector module, comprising:
a base plate with two opposite sides,
a light source mounted on one side of said two opposite sides of the base plate for emitting at least one light beam,
a micro-electro-mechanical-system (MEMS) scanning assembly mounted on the base plate at a distance from the light source for scanning the at least one light beam over a display area, and
a set of at least one lens mounted on said one side of the base plate between the light source and the MEMS scanning assembly,
wherein the MEMS scanning assembly has an arm mounted on and extending from the other side of said two opposite sides of the base plate, and has a scanning mirror being movably mounted on the arm and facing said other side of the base plate, and
wherein a light guide is mounted on the base plate or the arm for directing the at least one light beam from the lens set on said one side to the scanning mirror on the arm extending from said other side of the base plate.
