Abstract
A novel displaying method, two-field driving scheme, was proposed for
field sequential color LCDs without color filter. A spatially modulated
color backlight provided multi-primary low-resolution optical stimuli, which
were then compensated by an LC panel to display detailed colorful images.
That is, the manipulation on three (or more) spatial and two temporal
degrees of freedom was sufficient to convey full color information. The
simulation results showed that the proposed method achieved acceptable color
reproduction accuracy, average CIEDE2000 color difference (ΔE<sub>00</sub>) <3.The least number of fields particularly alleviated the demand for
fast-response LC modes in sequential-type LCDs. Furthermore, color break-up
suppression was observed due to less chrominance difference between the two
fields.
