Abstract
The field-sequential-color liquid crystal display (FSC-LCD) without a
color filter enables high light efficiency, wide color gamut, and low
material cost. However, the visual defect of color breakup (CBU) is
perceived when relative velocities exist between the screen image and the
human eye. We proposed the Stencil-FSC method with a 240-Hz field rate to
make CBU imperceptible. Given the Stencil-FSC method, the hardware
parameters were optimized to reduce hardware complexity while maintaining
sufficient suppression of CBU. After implementing Stencil-FSC on a 32-in
FSC-LCD, the image contrast ratio was shown to be ten times more than that
of a conventional CCFL LCD, and the average power consumption was reduced to
less than 35 W—a 67% savings in power consumption.
