Abstract

Despite its 3X optical efficiency, 3X pixel resolution, and 20% cost reduction, the field-sequential liquid crystal display (LCD) suffers from the color breakup phenomenon (CBU), which occurs when the red, green, and blue components of the same object project onto different retinal areas upon eye movement. To measure the human vision sensitivity to CBU, we conducted psychophysical experiments based on a linear dual-color saccadic display. To suppress CBU, we designed an electrooculogram (EOG) circuit to detect the saccadic eye movement. When saccades are detected, the contingent display reduces the image chroma on-the-fly by modulating the red/green/blue LED backlights such that the CBU artifacts are unperceivable. Otherwise, the contingent display stays in the normal mode to offer the best image quality. It is a pioneering work using brain-machine interface to solve the long pending challenge to the field-sequential LCD.
