摘要： A display system comprises a display panel substantially comprising a subpixel repeating group tiled across the panel in a regular pattern. The subpixel repeating group comprises at least one white subpixel and a plurality of colored subpixels. The display system further comprises input circuitry configured to receive input image data indicating an image for rendering on the display panel, and subpixel rendering circuitry configured to compute an output luminance value for each subpixel of the display panel. The subpixel rendering circuitry multiplies data values of a spatial portion of the input image data by at least one image filter kernel which comprises a matrix of coefficients arranged such that each coefficient represents a fractional part of one of said data values of the spatial portion of the input image data. The subpixel rendering circuitry is further configured to sharpen the output luminance values using a luminance signal.

摘要： If a pixel (106) of an image is displayed in a subpixel area (124) which does not contain a primary color needed to display the pixel, and saturated colors are present in or adjacent to the subpixel area, then some of the pixel's luminance is shifted (850) to adjacent subpixel areas on one but not both sides of the pixel to avoid blurring the pixel. Other embodiments are also provided.

摘要： Displays systems and methods for adjusting backlight illumination are disclosed wherein backlight illumination may be set low enough according to an error threshold amount in order to reduce backlight power consumption while maintaining a level of image quality. In one embodiment, image data is evaluated within a given frame and partitioned into histogram bins depending on the amount of backlight illumination requested or required by the image data. The histogram is traversed to provide an accumulative error measure. The error measure is compared against the error threshold and, if exceeded, the final backlight illumination may be set as a function of various illumination levels considered and possibly the first and a second threshold.

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： Sub-pixel rendering with gamma adjustment allows the luminance for the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel, while the chrominance can match the linear response of the human eye's chrominance channels. The gamma correction allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may be optimized for the gamma transfer curve of a display device in order to improve response time, dot inversion balance, and contrast.

摘要： An array and row and column line architecture for a display is disclosed. The array consists of a plurality of row and column positions and a plurality of three-color pixel elements. A three-color pixel element can comprise a blue emitter, a pair of red emitters, and a pair of green emitters. Several designs for the three-color pixel element are contemplated. The drive matrix consists of a plurality of row and column drivers to drive the individual emitters. The row drivers drive the red, green and blue emitters in each row. The red and green emitters in each column are driven by a single column driver. However, a single column driver can drive two column lines of blue emitters, a first column line and a second column line of the next nearest neighboring three-color pixel element. Methods of driving a three-color pixel element are also disclosed.

摘要： 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.

摘要： Sub-pixel rendering with gamma adjustment allows the luminance of the sub-pixel arrangement to match the non-linear gamma response of the human eye's luminance channel. For each of a subset of input sampled data indicating a region of an input image, a gamma-adjusted data value is generated for each input image data value in the subset using a local average of at least two input image data values. A sub-pixel rendering operation uses the subset of gamma-adjusted data values and the subset of input image data values to produce an output data value for each sub-pixel element on the display panel. A plurality of output data values collectively indicates an output image. The gamma adjustment allows the sub-pixel rendering to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques with gamma adjustment may improve image contrast in high spatial frequency portions of an image.
