Input image data indicating an image is rendered to a display panel in a display device or system that is substantially configured with a three primary color or multi-primary color subpixel repeating group using a subpixel rendering operation based on area resampling techniques. Examples of expanded area resample functions have properties that maintain color balance in the output image and, in some embodiments, are evaluated using an increased number of input image sample points farther away in distance from the subpixel being reconstructed than in prior disclosed techniques. One embodiment of an expanded area resample function is a cosine function for which is provided an example of an approximate numerical evaluation method. The functions and their evaluation techniques may also be utilized in constructing novel sharpening filters, including a Difference-of-Cosine filter.

A method of blending image data that includes displaying a first portion of an image from a first set of pixels according to a first mode in which color values of sub-pixels of the first set of the pixels are determined according to time-averaged colors of the corresponding backlight emitters. The method also includes displaying a second portion of the image from a second set of the pixels according to a second mode in which color values of sub-pixels of a second set of the pixels are determined independently for each of the colors of the corresponding backlight emitters. At an interface between the first portion and the second portion, the first portion and the second portion are generally linearly blended so as to form a blended portion of the image, and the blended portion is displayed.

A method of operating spatial sampling filters comprises detecting subpixel rendered areas, turning on a first set of spatial sampling filters for the subpixel rendered areas in response to detecting said subpixel rendered areas, detecting non-subpixel rendered areas; and turning on a second set of spatial sampling filters for the non-subpixel rendered areas in response to detecting the non-subpixel rendered areas.

A display device comprises a display panel comprising high brightness subpixel repeating groups—for example, RGBW display panels. Displays comprise subpixel repeating groups that include first and second primary color stripes and third and fourth primary color subpixels that are disposed on a checkerboard pattern. A subpixel rendering operation includes, or is followed by, a white subpixel adjustment operation that adjusts the brightness of the white subpixels in the areas of the displayed image that contain high spatial frequency features such as lines and text, in order to improve image quality such as image contrast.

Processing data for a display including pixels, each pixel having color sub-pixels, comprises receiving pixel data. Once the pixel data is received, processing data for a display includes converting the pixel data to sub-pixel rendered data, the conversion generating the sub-pixel rendered data for a sub-pixel arrangement including alternating red and green sub-pixels on at least one of a horizontal and vertical axis. Next processing data for a display includes correcting the sub-pixel rendered data if a condition exists and outputting the sub-pixel rendered data.

Displays systems and methods for dithering input image data to reduce quantization errors in a display system include inputting input image data to be rendered by said display system; applying a gamma table to the input image data to create a first intermediate image data; applying a dithering pattern, the dithering pattern comprising a checkerboard pattern, the checkerboard pattern depending upon the subpixel layout of the display. The display system may include a separate gamma table for each input color channel and apply the separate gamma table to perform white point adjustments for the display system.

A method of facilitating the display of an image. The method includes, in a display system comprising a display panel having pixels and a backlight having individually addressable colored light emitters configured to provide light to the pixels of the display panel, receiving image data corresponding to an image for display upon the display panel, the pixels each having a color to be displayed, so as to collectively display the image. The method also includes, for each pixel, evaluating whether the corresponding color to be displayed is out-of-gamut to the each pixel, so as to form a set of out-of-gamut pixels. A set of virtual primaries is determined so as to define intensities of light emitted by the colored light emitters of the backlight during display of the image, the virtual primaries determined according to the colors of the set of out-of-gamut pixels.

A display system includes a subpixelated display panel having subpixels in two saturated primary colors. In one embodiment, the primary colors are selected so as to be a substantially metameric pair for an achromatic color such as white. Information display efficiencies arise from utilizing a checkerboard arrangement for the two primary colored subpixels and from using subpixel rendering algorithms to render an image on the display. The bichromatic display may display a black and white image combined with a monochromatic image, or may provide the capability to overlay a first image from a first image source carried on a chromatic channel onto a second image from a second image source carried on a luminance channel, where the first image source detects light wavelengths that the Human Vision System is not sensitive to, such as infrared light. This latter embodiment of the bichromatic display system is suitable for night vision devices.
