Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying high resolution images using an adaptive temporal dithering scheme on display devices having two or more color planes. The adaptive temporal dithering scheme includes identifying the dither visibility of an image to be displayed by the color planes and adaptively applying temporal dithering to the color plane having the highest dither visibility. In one aspect, temporal dithering can be adaptively applied between two different color planes on a frame-by-frame basis based at least partly on the dither visibility of the image content.

Abstract: This disclosure provides systems, methods and apparatus for writing data to a display. The frame rate is improved by simultaneously and independently writing data to multiple common lines of the display. In some implementations, lines of common color are written simultaneously. In some implementations, more common lines of lower visual importance are written simultaneously than common lines of higher visual importance. In these implementations, colors of higher visual importance can be displayed at a higher resolution to maintain good image quality while still improving frame rate. Display element electrodes may be coupled along common lines in various ways to implement simultaneous writing to multiple common lines.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying high resolution images with reduced visible halftone noise. In one aspect, an image having a plurality of image pixels is displayed on a display device having a plurality of display pixels, by mapping the tone or color of each input image pixel onto the plurality of display pixels by assigning each display pixel a tone or color value in the color space associated with the display device that is in a neighborhood of the tone or color of each input image pixel and appears to have the same perceptual tone or color value as the image pixel and has a lower visible halftone noise. A size of the neighborhood can be selected based on the color gradient in various portions of the image.

Abstract: This disclosure provides methods, apparatus, and computer programs encoded on computer storage media for reduced low tone pattern visibility. In one aspect, the disclosed methods receive an input image including a plurality of pixels, quantize the plurality of pixels, set half-tone image pixels corresponding to the portion of the input pixels that are below a crush threshold to a crushed value, and diffuse the quantization error resulting from the quantizing to half-tone image pixels other than the portion. In some implementations, the half-tone image pixels are then output to an output device such as an electronic display.
