SEQUENTIAL COLOUR DISPLAY DEVICE

摘要

A driving scheme for colour wheels that use primary or primary and secondary colours 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. In one embodiment the total required light output is composed of shorter light pulses that are distributed among all suitable combinations of colours that are available from the colour wheel.
