Background

As shown in fig. 6, the projector of the prior art mainly projects the integrated light beams with different colors from a laser source 10 'through a fluorescent light source 60', and then the integrated light beams are divided into parallel light beams 81', 82', 83 'with different three colors of red, green and blue by a phase rotator 70', so as to remove the light beams with unwanted colors. Then, after the red, green and blue parallel light beams 81', 82' and 83' are reflected by a reflector 20', the blue light beam 83' is reflected by a blue beam splitter 21', the green light beam 82' is reflected by a green beam splitter 22', and the red light beam 81' is reflected by a red light reflector 23', so that the three different light beams 81', 82' and 83' are spatially separated as shown in the figure, and then the blue light beam 83' and the red light beam 81' are respectively inverted by 90 degrees by a reflector 24' and a reflector 25 '.

With the above structure, the three red, green and blue light beams 81', 82' and 83' are transmitted in three directions different by 90 degrees. Then, a U-shaped structure 30 'is disposed in the propagation direction of the three light beams, the U-shaped structure 30' has three faces, each of which is an LCD panel 31', 32', 33', and each LCD panel 31', 32', 33' is inputted with an image from an image source (not shown), so that the three different light beams 81', 82', 83 'respectively pass through the three LCD panels 31', 32', 33' to form a blue image, a green image and a red image, and the prism 40 'is disposed inside the U-shaped structure 30' so that the blue image, the green image and the red image form parallel and synchronous images, and then are projected on a screen 91 'through a lens assembly 90', so as to form a color projected image.
