  • Publication number: 20080252581
    Abstract: 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.

  • Publication number: 20080186325
    Abstract: 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.

  • Publication number: 20070206013
    Abstract: 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.

  • Patent number: 7221381
    Abstract: The 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 algorithms to operate independently of the actual gamma of a display device. The sub-pixel rendering techniques disclosed with gamma adjustment can be optimized for a display device gamma to improve response time, dot inversion balance, and contrast because gamma correction and compensation of the sub-pixel rendering algorithm provides the desired gamma through sub-pixel rendering. These techniques can adhere to any specified gamma transfer curve.

  • Patent number: 5479079
    Abstract: A travelling robot body carries a first detector which is turnable with the body for sensing changes in direction of travel of the robot body. In order to compensate for errors by the first detector, the robot body carries a compensation system for determining an error compensation factor that can be applied to signals emitted by the first detector. That system which performs its function prior to operation of the robot, comprises a drive mechanism for turning the first detector relative to the robot body while the body is stationary, whereby the first detector emits a first signal representative of a sensed turning angle of the first detector. A second detector is mounted on the robot body for determining the actual turning angle of the first detector which occurred. By comparing the sensed turning angle from the first detector with the actual turning angle from the second detector, an error connecting factor can be calculated by a control mechanism.
