Abstract:
In a multi-color reflective display system having a controllable display cell with plural non-sequential color filters that transmit generally different color components with spectral overlaps between them, ambient light being transmitted into the display cell and reflected back through it, the display cell forming a display image in accordance with image data provided by an image data source, the improvement comprising:a color filter cross-talk compensator that receives the image data provided by the image data source and generates cross-talk compensated color component drive signals that are delivered to the display cell, the cross-talk compensated color component drive signals compensating for the overlapping color components transmitted by the color filters for the generally different color components; and an illumination source selector for selecting the ambient light as being one of plural predefined ambient illumination sources, the cross-talk compensator compensating for the overlapping color components transmitted by the color filters differently according to the ambient illumination source indicated by the illumination source selector.
