Abstract
An active matrix display panel is operated by a color sequential system to form color images. A color generator is disposed between a light source and the display panel for sequentially providing red, green and blue light. A color sequential drive circuit controls the color generator and the pixels of the display panel. The color generator is preferably a multi-stage multiple wavelength blocking filter incorporating fast switching surface stabilized liquid crystal cells.
