Color Breakup Reduction by 180Hz Stencil-FSC Method In Large-Sized Color Filter-Less LCD-TVs

Abstract

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 farther hardware implementation, the number of backlight divisions of 32x24 was optimized while considering CBU suppression and image fidelity.
