Paper Abstract

The paper presents two models to reduce the visibility of rainbow effect for field sequential color (FSC) LCDs. It was done by changing the LED backlight state, introducing crosstalk among the R/G/B LEDs and finally modified the RGB signals to minimize its image color differences to its original state. The results of our simulations suggested that the proposed methods would reduce the visibility of rainbow effect to some extent. However, its performance was quite image-dependent. How to reduce its computational cost and calibrate the LED backlight accurately is a great challenge to implement the models on real FSC LCDs.
