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 and mechanisms for providing illumination of a display. In an embodiment, a light guide includes a first portion to receive light, a second portion to output some or all of the light, and a third portion configured to propagate the light between the first portion and the second portion. The third portion forms a first deflection structure which adjoins, and extends between, respective surface regions of the first portion and the second portion. A light source is coupled to provide edgewise illumination of the light guide via the first portion. In another embodiment, the light propagates through the third portion and into a region, between two parallel planes, in which the second portion is located.

Abstract: A method performed by a processor of a electronic device, including rendering (402), on an electronic display, a line segment having a first direction and moving in a second direction. The method also includes a step of determining (404) whether the direction of the line segment (the first direction) is in the same direction that the line segment is moving (the second direction). If the processor determines that the line segment is not moving in the same direction of the direction of the line segment (the first direction), then the processor performs (408) a first action, such as adjusting the color intensity of the line segment. If the processor determines that the line segment is moving in the same direction of the direction of the line segment (e.g., the two directions are substantially parallel to each other), then the processor performs (406) a second action.

Abstract: A dual-sided electrophoretic display (700) having a first region (701) and a second region (702) is provided. Each of the first region (701) and the second region (702) includes selectively operable members (703,704) that function as pixels for presenting images on the electrophoretic display (700). Each of the selectively operable members (703,704) is driven by a driver circuit (710) by way of corresponding thin film transistors and capacitors (742,742), which are opaque. As the selectively operable members (704) of the second region (702) are bigger than are the selectively operable members (703) of the first region (701), the aperture ratio of the selectively operable members (704) of the second region (702) is greater than in the first region (701) when viewed from the rear side (730). Thus, a contrast ratio of the second region (602), when viewed from the rear side (730) is sufficiently high that text, icons, and characters presented in the second region (602) are legibly visible on the rear side (730).
