<p>A colour wheel for a sequential colour display is suggested, which has primary colour filter segments (R, G, B) and at least one secondary colour filter segment (C, M, Y). A driving scheme for the inventive colour wheel as well as for known colour wheels reduces the colour separation by temporally locating the light pulses required for generating a desired colour as close together as possible. In one embodiment, the pulse length increases in a direction away from a transition between a secondary colour filter and a corresponding complementary primary colour filter for light pulses of the respective colours. A driving circuit extracts driving signals for primary and secondary colours from primary colour input signals. The driving circuit further compares the driving signals with predetermined limiting values for preventing clipping.</p> |
