Abstract

The present invention relates to an RGBY miniature projector, and the projector comprises a plurality of RGBY LED light sources (10), a condenser lens (20), an optical modulator (30) and a projectiondevice (40), wherein the plurality of RGBY LED light sources (10), the condenser lens (20), the optical modulator (30) and the projection device (40) are sequentially disposed on the same optical path. The projector also comprises an optical driver (50) and an optical modulator (70), wherein the optical driver (50) is electrically connected with the RGBY LED light sources (10) and the optical modulator (70). According to the invention, the projector employs the RGBY LED light sources, so the projector is more delicate in color, is small in size, is low in energy consumption and is flexible incontrol.

Description

technical field [0001] The invention belongs to the technical field of micro-projection, and in particular relates to an RGBY micro-projector. Background technique [0002] In recent years, LED technology has developed rapidly, and the luminous efficiency is also improving rapidly. The miniature projection module used for personal portable electronic products has emerged suddenly due to the advantage of small size of LED. With the improvement and further improvement of LED light-emitting materials, light-emitting layer structure, chip structure, crystal growth control, etc., more and more advantages will emerge in the field of micro-projection display light sources, and it is bound to bring the low cost of micro-projection. Come new opportunities. The optical structure of the micro projector is complex, therefore, there is a bottleneck when the volume is reduced to a certain extent. [0003] Therefore, it will be extremely important to provide a miniature projector with a...
