A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.

An electronic device may display image content via an electronic display by controlling light emission from display pixels of the electronic display. A processor of the electronic device may receive image data destined for a defective display pixel (e.g., dim pixel, dead pixel). The processor may convert a gray level of the image data into a luminance domain to generate a target luminance that would have been emitted by the defective display pixel had the display pixel not been defective. After selecting a compensation mask, the processor may distribute the target luminance of the defective display pixels to nearby non-defective pixels of the electronic display to conceal the presence of the defective display pixel.

An image is rendered on a display having a limited number of primary colors by (104) combining input data representing the color of a pixel to be rendered with error data to form modified input data, determining in a color space the simplex (208—typically a tetrahedron) enclosing the modified input data and the primary colors associated with the simplex, converting (210) the modified image data to barycentric coordinates based upon the primary colors associated with the simplex and (212) setting output data to the primary having the largest barycentric coordinate, calculating (214) the difference between the modified input data and the output data for the pixel, thus generating error data, applying (106) this error data to at least one later-rendered pixel, and applying the output data to the display and thus rendering the image on the display. Apparatus and computer-storage media for carrying out this process are also provided.

A method, system, apparatus, and/or device for displaying a portion of data so as to not obstruct a portion of a central visual field. The method, system, apparatus, and/or device may include a display configured to display data and a processing device coupled to the display. The processing device may be configured to determine a position of an eye of a viewer with respect to the display, define a first region of the display substantially corresponding with a peripheral vision field of the eye, define a second region of the display substantially corresponding with a central visual field of the eye, send a first portion of the data to be displayed at the first region, and send a second portion of the data to be displayed at the second output region such that a portion of the central visual field is unobstructed by the second portion of the data.

An image display device includes a first pixel data calculator calculating first pixel data for a pixel of attention based on a first error value for a pixel adjacent thereto in the same error diffusion block; a second pixel data calculator calculating second pixel data for the pixel of attention based on a corrected error value for the adjacent pixel; a first error value calculator calculating the first error value based on the first pixel data; a second error value calculator calculating a second error value based on the second pixel data; and a corrected error value calculator calculating the corrected error value by correcting the second error value in a direction in which the second error value approaches the first error value in accordance with whether the pixel of attention is located within a predetermined range from a border among a plurality of error diffusion blocks.

A display compensation method for a display panel, a display compensation device, a display device and a storage medium. The display compensation method includes: acquiring compensation data of i pixels adjacent to the target pixel of the display panel respectively; deleting deviation data from the compensation data of i pixels; calculating the compensation data of the target pixel according to the remaining compensation data; i is an integer greater than 2.

In one embodiment, a computing system may receive a target color and a propagated error for a pixel location. The system may determine an error-modified target color for the pixel location based on the received target color and the propagated error. The system may identify, based on a location of the error-modified target color in a three-dimensional color space, a subset of pre-determined colors in the three-dimensional color space. The error-modified target color may correspond to a weighted combination of the subset of pre-determined colors. The system may determine a pixel color for the pixel location based on the subset of pre-determined colors and respective weights associated with the subset of pre-determined colors. The system may determine, based on the pixel color, driving signals for light-emitting elements associated with the pixel location. The system may output the driving signals to control the light-emitting elements associated with the pixel location.

A display device includes a display panel including a plurality of pixels, and a panel driver configured to receive input data, and to drive the display panel based on the input data. The panel driver includes a partial still image detector configured to detect a still image data portion in the input data by determining whether at least a portion of the input data represents a still image, and a command decoder configured to extract command data from the input data by decoding the still image data portion in which the command data are encoded.
