We proposed the “180Hz Stencil‐FSC” method to suppress color break‐up (CBU) infield‐sequential‐color (FSC) LCDs. Applying local color‐backlight‐dimming technology to FSC‐ LCDs, a “green‐based multi‐color” field‐image was generated to show most image luminance at the first field and effectively suppressed CBU even compared to field‐rate increasing methods. In addition, for further hardware implementation, the number of backlight divisions of 32 ×24 was optimized while considering CBU suppression and image fidelity.
