<p>A projection display system comprises a light source (112) that generates non-polarized light having at least two polarization states and having a first color component, a second color component, and a third color component. At least one color selection device (114) selectively transmits at different times one of the second and third color components. The system has at least four polarized light modulators (130, 132, 148, 150), two of the light modulators (130, 148) each generating a respective image associated with each respective polarization state of the first color component, and two of the light modulators (132, 150) each generating a respective image associated with a respective polarization state of one of the second and third color components transmitted by the color selection device (114). The system also has a projection lens (140) for projecting the images from the polarized light modulators (130, 132, 148, 150). Alternative projection display systems are disclosed, together with a method for projecting color images. <IMAGE></p> |
