  • Patent number: 7497576
    Abstract: A projection display is disclosed. The present invention can eliminate the reflective light on the internal optical surface of the optical system, using the phase plate and linear polarizer, in the color sequential driving of illuminating at least two colors on the single display panel at a random moment. The phase plate converts the incident light from a linearly polarized light to a circularly polarized light, and vice versa. And, the linear polarizer transmits the linearly polarized light of the incident light in the specific direction. Therefore, the present invention prevents the degradation of color purity generated from the mutual intrusion of light of at least two colors, thereby enhancing quality of color image.
