Abstract

The utility model provides an optical engine of a projector, and the optical engine of the projector can be used in a working process. Red light emitted by the first reflective bowl sequentially passes through the first incident fly's-eye lens, the first emergent fly's-eye lens, the first collecting lens, the red light dodging rod and the red light contrast compensation sheet, then passes through the light modulation mechanism and the red light LCOS display chip and then enters the square color combination prism. Green light emitted by the second reflective bowl sequentially passes through a second incident fly's-eye lens, a second emergent fly's-eye lens, a second collecting lens, a green light dodging rod and a green light contrast compensation sheet, then passes through a light modulation mechanism and a green light LCOS display chip and then enters a square color combination prism. Blue light emitted by the third reflective bowl sequentially passes through a third incident fly's-eye lens, a third emergent fly's-eye lens, a third collecting lens, a blue light dodging rod and a blue light contrast compensation sheet, then passes through a light modulation mechanism and a blue light LCOS display chip and then enters a square color combination prism. And the emergent surface of the square color combination prism faces the projection lens.
