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.

Abstract: Techniques for generating pixel shifting patterns for organic light emitting diode (OLED) displays are provided. Pixel usage data for the OLED display can be accumulated. Areas of the OLED display susceptible to burn-in damage can be identified based on the accumulated pixel usage data. A pixel shifting pattern can be generated based on the accumulated pixel image data and data relating to an image to be displayed. The pixel shifting pattern can be generated to avoid the areas identified as susceptible to burn-in damage. The pixel shifting pattern can be applied to the image to be displayed to generate modified image data. The modified image data can limit further damage to the OLED display and thereby delay the onset of undesirable burn-in effects.
