Hybrid spatial-temporal color synthesis and its applications

— A novel approach of synthesizing display color by hybrid color processing in both the spatial and temporal domains is introduced. The rational basis for this approach is found in vision science, and more particularly in the spatial and temporal characteristics of the human visual system. Various examples of the new approach, aiming at different display‐performance objectives, are described. Hybrid spatial‐temporal color synthesis can be used to generate a three‐primary RGB display, the analysis of which reveals a higher spatial resolution and a lower fixed‐pattern noise. The concept has also been used to build, based on a conventional LCD panel in combination with an adapted backlight system, a six‐primary LCD TV with a 22% wider color gamut. Finally, the approach is demonstrated in a four‐primary mobile LCD and results in lower cost combined with a higher display luminance and a wider color gamut.
