Abstract: The present disclosure is directed to quantum dot LCD display systems and methods that use a digital optics polarizer to beneficially and advantageously provide enhanced performance and substantially lower power draw. The digital optics polarizer is disposed as a metasurface between the LCD layer and the quantum dot layer within the LCD display device. The digital optics polarizer is formed using a dielectric material, such as TiO2, that does not cause reflectivity and ohmic loss issues typically encountered with wire grid polarizers. The digital optics polarizer may be patterned, deposited, or otherwise disposed across all or a portion of the LCD layer, the quantum dot layer, or may be “sandwiched” between and proximate the LCD layer and the quantum dot layer. The elimination of ohmic losses in the digital optics polarizer significantly improves the energy efficiency of the LCD display.
