    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.

    摘要: A display system (110) has a subpixel array (120) and a light source (140). In normal mode, image data (164) are processed by the display system to generate subpixel values (174) for the subpixels (130) and to generate a light source control value (BL) for the light source (140). In bypass mode suitable for testing new types of image-data processing, the subpixel values and the light source control value are generated by an external system (210) and are provided to the display system which is operated in bypass mode. The light source control value is not provided separately from the subpixel values but is encoded into some bits of the subpixel values for compatibility with older interfaces. The light source control value is encoded into the subpixel values' MSBs in case the subpixel values could be truncated. Other features are also provided.

    摘要: Liquid crystal display backplane layouts and addressing for non-standard subpixel arrangements are disclosed. A liquid crystal display comprises a panel and a plurality of transistors. The panel substantially comprises a subpixel repeating group having an even number of subpixels in a first direction. Each thin film transistor connects one subpixel to a row and a column line at an intersection in one of a group of quadrants. The group comprises a first quadrant, a second quadrant, a third quadrant and a fourth quadrant, wherein the thin film transistors are formed in a backplane structure adjacent to intersections of the row and column lines. The thin film transistors are also substantially formed in more than one quadrant in the backplane structure.

    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.

    摘要: Display systems that employ input gamma dithering and dynamic backlight control. Embodiments relate to disabling input gamma dithering during periods when there is a change in the scale value by which image data is scaled due to dynamic backlight control. In this manner, input gamma dithering is selectively applied only during those times when data scaling due to dynamic backlight control is constant.
