Abstract
A color image display system including a thin-film display device is provided. The device is driven by a current for each pixel of the device and is designed to display colors corresponding to a plurality of color signals. The display system includes a color signal converter for converting the color signal ratio of the plurality of color signals of a color signal source to a ratio of signals suitable for the colors of the thin-film display device. In this way, the color image display system provides an improved image quality, even when colors of light emitted from the thin-film display device are slight variations from NTSC or other image signals, or the current/luminance conversion efficiencies for various colors are not the same level.
