摘要:
Display systems and image processing methods process pre-subpixel rendered images embedded in input color image data. The display systems include a pre-subpixel rendered (P-SPR) image detector that detects locations of a marking code that marks the portion of the input data that has been pre-subpixel rendered and which is ready for direct display. Several display system embodiments comprise first and second image data paths; the input data that requires subpixel rendering proceeds along the first path while the P-SPR image data proceeds along the second path. Another display system embodiment processes the combined input and P-SPR data along a single data path. Techniques for marking and detecting P-SPR image data using two distinct marking codes are presented in the context of the subpixel layout of the display. Techniques for using P-SPR data to display high-quality graphical symbols (e.g., font glyphs) are suitable for small, low-cost display devices.

Several embodiments of the present application disclose techniques, systems and methods for changing or rendering input image data that may assume a first white point for a given display into image data to be rendered under a second—assumed, desired or measured—white point of the display.

A method for forming a multipixel image on an imaging surface is disclosed. The method comprises projecting for each pixel in the multipixel image a plurality of beams of different colors towards the imaging surface. Each of the plurality of beams for each pixel is directed along a path towards the imaging surface, such that images formed on the imaging surface from each beam are convergent by substantially less than about 100%. An optical projector, a subtractive color flat panel display, and a CRT video display are also disclosed.

A three-color pixel element for a display comprises a blue emitter disposed at the origin of a rectangular coordinate system having four quadrants, a pair of red emitters and a pair of green emitters spaced apart from the blue emitter and symmetrically disposed about the origin of the rectangular coordinate system in a first and second pair of opposing quadrants.

The present application discloses several methods, techniques and systems for rendering source image data onto high brightness subpixel arrangements—for example, RGBW display panels. Additionally, these techniques have application for rendering data onto 3-color displays as well.
摘要:
Methods and systems for motion adaptive filtering detect movement of text or areas of high spatial frequency in one frame to another frame of an image. When such movement is detected and meets a certain level or threshold, the subpixel rendering processing of such text or areas of high spatial frequency may be changed.
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:
Various embodiments of a sub-pixel repeating group are disclosed. In one embodiment, an octal subpixel repeating group may comprise three-color (red, green and blue) sub-pixels with blue colored subpixel comprising twice the number of positions within the octal sub-pixel grouping as the red and green colored sub-pixels. In another embodiment, a subpixel repeating group comprises two rows of eight “split” subpixels comprising three primary colors and a non-saturated neutral, or white, subpixel functioning as a primary color.

Dot inversion schemes are disclosed on novel display panel layouts with extra drivers. A display panel comprises substantially a set of a subpixel repeating group comprising a pattern of six columns and two rows: RRGBBG BBGRRG wherein at least one set of adjacent column subpixels share image data from a single driver upon the display panel.
