Projector module for micro-display with three-typed LEDs

The invention relates to a projector module for micro-display with three-typed LEDs characterized in that the projector module for micro-display with three-typed LEDs comprises a blue LED micro-display module, a green LED micro-display module and a red LED micro-display module. The blue LED micro-display module, the green LED micro-display module and the red LED micro-display module are arranged on three sides of a beam splitter prism module respectively. A blue, a green and a red light are emitted respectively by the blue LED micro-display module, the green LED micro-display module and the red LED micro-display module through the same side of the beam splitter prism module. The blue LED micro-display module is placed on the opposite side of a red light reflecting prism of the beam splitter prism module, the red LED micro-display module is placed on the opposite side of a blue light reflecting prism of the beam splitter prism module and the red LED micro-display module is placed on the light emergent side of the beam splitter prism module. According to the invention, the projector module for micro-display with three-typed LEDs is simple in structure, small in size, low in light loss, effective in utilization and avoids the defects of existing technology scheme in utilizing external optical sources.
