Abstract: This disclosure provides systems, methods and apparatus for reducing flicker in display devices. In one image formation process, the controller can determine a number of subframes to be displayed for a subfield based on a temperature of a display apparatus. In some implementations, the controller can determine dithering parameters based on the determined number of subframes, and perform dithering on pixel intensity values based on the determined dithering parameters. In some implementations, a vector error diffusion technique can be utilized for performing dithering. In some implementations the controller can determine drive voltages for light modulators and drive currents for light sources used for displaying the subframes, based on the temperature of the display apparatus.

Abstract: Disclosed herein is a dual lens system capable of maintaining a substantially constant color within a well-defined angular range of light incident on a reflective pixel. Each reflective pixel (or subpixel) of a display may include a primary lens and a field lens. The field lens may be positioned at a distance equal to a focal length of the primary lens. Each plane wave of incident light arriving at the primary lens aperture may be focused on a unique location of the focal plane, but may emerge from the field lens within the same range of angles. If a reflective pixel is positioned below the field lens, the reflected color should be substantially the same within a range of viewing angles. The range of angles may be defined by the numerical aperture of the lens system and by black mask material disposed between the reflective pixels or subpixels. Thus, a reflective display includes an array of reflective pixels; an array of primary lenses, each of the primary lenses corresponding to a distinct one of the reflective pixels; and an array of field lenses, each of the field lenses corresponding to a distinct one of the reflective pixels and one of the primary lenses, each of the field lenses being positioned at a distance from a corresponding primary lens, the distance being a focal length of the corresponding primary lens, each of the field lenses being disposed proximate a corresponding reflective pixel.
