Single-panel color image display apparatus

Abstract

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.
