Content-Dependent Reduction of Static Color Breakup on Field Sequential Color LCDs

Field sequential color (FSC) LCDs form color images by sequentially displaying subfield images. Because color filter attenuating light transmission is not required, FSC LCDs can reduce power consumption considerably. However, their sequential display scheme results in undesirable color artifacts that degrade the perceived image quality. This paper proposes a new content-dependent static color breakup (CBU) reduction method for FSC LCDs with 240-Hz frame rate. In addition, two performance indices are defined to examine the effectiveness of the backlight color selections. Experimental results indicate that the proposed method effectively reduces the visibility of static CBU.
