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.

摘要： A highly efficient projection system is provided, including a light source, a color separator, a scrolling unit, a light valve, a projection lens unit, and a polarization conversion system. The color separator separates an incident beam according to color. The scrolling unit includes at least one lens cell and converts a rotation of the lens cell into a rectilinear motion of an area of the lens cell through which light passes so the incident beam is scrolled. The light valve processes a beam transmitted by the color separator and the scrolling unit, according to an image signal and forms a color picture. The projection lens unit magnifies the color picture formed by the light valve and projects the magnified color picture onto a screen. The polarization conversion system is installed between the color separator and the light valve and converts the incident beam into a beam with a single polarization.
