Abstract (en)
[origin: WO2007137994A2] Each color image is broken down into at least one series of at least three successive primary images of different primary colors which are displayed successively by modulating the activation pulse of the pixels of an imaging device; the invention requires that the spread of the pulse phase of the pixels be shortened over the three successive sub-frames: the pulse periods of the pixels of the first primary image are displaced to the end of the sub-frame of the first image, and the pulse period of the pixels of the third primary image are displaced in the sub-frame of the third primary image towards the beginning of the sub-frame of this third image. This has the beneficial effect of reducing color break defects.
