摘要： A color projection system includes a light source, a rotatable drum having a plurality of differently Colored bands, and a light modulation panel on which light beams reflected by the colored bands can be directed by way of scrolling. The apparatus directs the light beam from the light source onto a first group of juxtaposed bands. The light beam on each band is split and reflected into light beams having complementary colors and different directions of polarization. Light beams having a first direction of polarization are directed onto the light modulation panel, and light beams having a second direction of polarization are reflected onto a second rope of bands of the drum. The second group of bands is shifted by at least one band with respect to the first group of bands.

摘要： Power is saved in a color display system (200) by sacrificing color rendering capability in favor of brightness capability. The system (200) comprises a plurality of light emitters (202,204,206). The emitters are fed with a respective initial electric power input which adds up to a first total electric power input, whereby each light emitter provides an initial first color intensity, a second color intensity and a third color intensity, respectively, which, in combination, are perceivable to the human eye as an initial total brightness. Power input is then reduced to a second total power input by feeding each light emitter with a respective second electric power input, whereby the second total power input that is less than said first total power input is obtained.

摘要： A scrolling colour projection system comprising a lamp (4) with a pulsed drive current (20) and a colour scanner (6, 8a, 8b, 8c, 9) for generating a light beam (5b) with a plurality of scrolling colour fields, which is arranged to illuminate a display device (3) to produce a projection of an image generated by the display device. The system further includes a filtering element (31) arranged in the light path between the lamp and the projected image, and the transmission of the filtering element (31) is synchronized with the lamp current so as to cancel an intensity peak in the lamp flux. The filtering element thus effectively removes the impact of the current pulse on the light intensity, resulting in a constant intensity in the projected image, and avoiding any interference patterns.
