Abstract:
A mechanism for mitigating undesired color image breakup artifacts arising in display systems that exploit the principle of field sequential color generation. By suitably reducing the time interval during which image information strikes the moving retina, such that the differential position for the respective red, green, and blue components of the image falling upon the moving retina does not exceed the diameter of a retinal cone or rod, the cause of the breakup is negated and the image becomes unitary as expected: the eye sees the image as if all the components arrived at the same time. The truncation of light emission into shorter time frames necessitates a compensatory increase in imaging light intensity, such that the net amount of photonic flux striking the retina, averaged over time, remains unchanged. The mechanism can be applied to systems with discrete red, green, and blue sources as well as to color-wheel-based systems.
