The higher and higher power consumption of LCD-TVs is accompanied by an increase in panel size. By eliminating two of the most power hungry optical components: color filters and polarizers, the stencil-field-sequential-color (Stencil-FSC) with RGBW-LED backlight is applied to LCDs with 120–240 Hz field rates to not only efficiently suppress color breakup but also yield an ultra-low average power consumption. The optical power consumption can be reduced to 13% compared to that of current FSC-LCDs. As a result, a 42-in LCD-TV may only require 9 W optical power consumption.
