When the display panel comprises a multi-primary subpixel arrangement having a white (clear) subpixel, the backlight control techniques allows the white subpixel to function as a saturated primary display color. In another embodiment, the display system may calculate a set of virtual primaries for a given image and process the image using a novel field sequential control employing the virtual primaries. In another embodiment, a display system comprises a segmented backlight comprising: a plurality of N+M light guides, said light guides forming a N×M intersections; a plurality of N+M individually addressable light emitter units, each of said N+M light emitter unit being associated with and optically connected to one of said N+M light guide respectively.

    摘要: In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values. A weighting module produces a resulting clamped value from the first and second clamped values. A final output image value is derived from the resulting clamped value. Other embodiments of the display system include pre-reduction modules and adjustable GMA modules.

    摘要: Displays systems and methods for selectively reducing or compressing image data values within an image are recited. Display systems transform input image data from one input gamut hull or space to another target gamut hull or space that is substantially defined by different subpixel repeating groups comprising the display. Display systems described herein comprise a selective compression unit, said unit surveying said input image data to produce intermediate image data based upon a segmentation of the input image according to a parameter. Suitable parameters for segmenting the image include one or more of the following: spatial segments, chromatic segments or temporal segments. A selective compression amount may be determined so as to substantially maintain local contrast of the image data within a given segment.

    摘要: A method of determining implied sample areas for each data point of each color in a source pixel data specified in a first sub-pixel format is used for sub-pixel rendering an image on a display specified in a second sub-pixel format. Each of the first and second sub-pixel formats comprises a plurality of colored sub-pixels. The method comprises determining a geometric center of each colored sub-pixel of the first format to define a sampling point; and defining each implied sample area by forming lines that are substantially equidistant between the sampling point of one colored sub-pixel and the sampling point of another neighboring same color colored sub-pixel. A similar technique may be used for determining resample areas for computing color values for rendering an image specified in a first sub-pixel format on a display substantially comprising a plurality of colored sub-pixels arranged in a second sub-pixel format.

    摘要: In a first embodiment, a method of converting a source pixel data of a first format for a display of a second format having a plurality of three-color pixel elements comprises determining implied sample areas for each data point of each color in the source pixel data of the first format. The resample areas for each emitter of each color in the display is also determined. A set of fractions for each resample area is formed. The denominators are a function of the resample area and the numerators are the function of an area of each of the implied sample areas that at least partially overlaps the resample areas. The data values for each implied sample area is multiplied by its respective fraction and all products are added together to obtain luminance values for each resample area.
