We propose an efficient LCD system to simultaneously recycle the backlight according to its color and polarization. These novel polarizing color filters offer high transmittance, high extinction ratio and large angular tolerance. In combination with a directional backlight, our system can achieve ~3X higher optical efficiency for ultra‐low power operation.
