Abstract

A pico-projection device performs three-color mixing and scanning on a projection surface by using laser diodes or light-emitting diodes for providing light of three different wavelengths as a light source and a light source module and a polychromatic light concentrator for light focusing and three-color light source mixing, employing a two-dimensional reflective scanning mechanism, and adapting three-color light source signal modulation before using a projection lens module to form images and display dynamic color pictures on a projection screen. By means of manual or auto focus, the device is capable of providing a same resolution in different projection distances or on different screen sizes. The device also has an eye safety protection mechanism to perform instant monitoring for preventing any harm caused to human eyes by the light projected from the device. Thus, the device can become another display device or portable display unit for any object to be displayed.
