摘要:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for displaying high resolution images using examples of a halftoning method based on diffusing quantization error from a subpixel displaying a color to one or more subpixels that display a different color.

This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media for producing line multiplied images with better visual appearance. The line multiplying is shifted for one of the colors of the display with respect to at least one other color of the display.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling brightness of a display based on ambient light conditions. In one aspect, a display device can include a reflective display and an auxiliary light source configured to provide supplemental light to the display. The display device further can include a sensor system configured to determine an illuminance of ambient light, and a controller configured to adjust the auxiliary light source to provide an amount of supplemental light to the display based at least in part on the determined illuminance. In one aspect, the amount of supplemental light remains substantially the same or substantially increases in response to increasing illuminance when the illuminance is below a first threshold, and substantially decreases in response to increasing illuminance when the illuminance is above a second threshold that is greater than or equal to the first threshold.

This disclosure provides systems, methods and apparatus for device and methods for high reflectance multi-state architectures. In one aspect, a display device can include a plurality of reflective pixels including subpixels. Each subpixel can be selectively switched among first, second, and third states, with each state having a different spectral reflectance. Each subpixel has a spectral reflectance associated with a first set of primary colors and with a second set of primary colors. At least one of the colors in the second set of primary colors can be different from the colors in the first set of primary colors. The first set of primary colors can include colors that combine to produce white. A combination of colors of the first set of primary colors can have a brightness that is higher than the brightness of the combination of colors of the second set of primary colors.

Displays, and methods of displaying images with the displays, which have quantized display characteristics for each of the pixels are disclosed. The displays and methods relate to both spatially and temporally dithering images so that the effective resolution of the display is higher than the result of the native spatial and intensity resolutions of the display, defined by pixel size, pitch, and number of quantization levels of each of the pixels.
