SEQUENTIAL COLOUR DISPLAY DEVICE |
摘要 |
<p>A display device produces colour images by sequentially projecting monochromatic images. Multispectral light is projected via optical means and a filter arrangement with changeable primary colour filters onto an imaging device. For each primary colour the imaging device produces a number of constant-length pulses corresponding to a desired brightness level. The pulse length is chosen to be as short as possible for a first primary colour. The pulse length for the other primary colours is adapted according to the respective share of the corresponding colour filters in the colour wheel. The time during which secondary colours are produced due to a transition between two primary colour filters is increased by increasing the aperture of the optical means, by spatially relocating the focal point of the optical means for a disc-like filter arrangement, or by accordingly adding pure colour light at the onset and the end of a transition between two colour filter segments which produces secondary colour light. Secondary colour light is used to increase the brightness of the projected image.</p> |
