    摘要： A projection system including a light source, a color separator, a scrolling unit, a light valve, a wire grid polarization beam splitter, and a projection lens unit is provided. The color separator separates an incident beam according to color. The scrolling unit scrolls the color beams. The light valve processes an incident beam according to an image signal and forms a color picture. The wire grid polarization beam splitter is disposed between the scrolling unit and the light valve and transmits or reflects an incident beam according to a polarization of the incident beam. The projection lens unit magnifies the color picture formed by the light valve and reflected by the wire grid beam splitter and projects the magnified color picture onto a screen.

    摘要： A single-panel color image display apparatus realizing a wide color gamut includes a light source, a colored light separator, and a light valve. The colored light separator has four or more dichroic filters of reflective type which separate a light emitted from the light source according to a wavelength. The light valve controls the light that is emitted from the light source and separated by the colored light separator according to color, on a pixel-by-pixel basis according to an input image signal, and forms a color image. By performing color scrolling using a scrolling unit having a spiral array of lens cells, the same resolution as that obtained when using a color wheel can be realized and the same light efficiency as that obtained when using a three-panel color image display apparatus can be realized.
