<p>A rotating periodic color-regulating module of the image display device is disclosed to improve the usage of light. The rotating periodic color-regulating module comprises a color separating light guide and a color-regulating processor. By using a grating element installed in front of the color separating light guide, the incident light is interleaved into three parts of different wavelengths, red (R), green (G) and blue (B), propagating toward the corresponding color filters. Part of the light is reflected by the color filters, then reflected by the mirror around the grating element, and goes back to the color filters. The incident light is divided into three uniform beams of light, R, G and B, to the color-regulating processor. The color-regulating processor changes the outgoing position and order of the light beams periodically and rapidly for displaying image.</p> |
