A novel method, local primary desaturation (LPD), was proposed to suppress color breakup for field-sequential color (FSC) LCDs. The LPD method was implemented on a 32-inch OCB-mode color filterless FSC-LCD with 35 × 19 individually controllable RGB-LED backlight segments. The performance of the method was evaluated via color breakup simulations and with a perception test. We also evaluated the image quality and the amount of power savings. The results showed that the LPD method reduced the color breakup from very annoying to almost imperceptible while maintaining a good image quality and reducing the power consumption significantly.
