摘要： A system is provided for using raw grayscale image data, representing images to be displayed in successive frames, to drive a display having pixels that include a drive transistor and an organic light emitting device. The system defines high and low ranges of raw grayscale image data, and determines whether the raw grayscale image data for each pixel falls within the high range or the low range. Raw grayscale image data that falls within the low range is converted to higher grayscale values, and the pixels are driven with currents corresponding to the higher grayscale values during time periods that are shorter than complete frame time periods. Raw grayscale image data that falls within the high range is converted to higher grayscale values, and the pixels are driven with currents corresponding to the higher grayscale values during time periods that are shorter than complete frame time periods and different from the time periods of the low range image data. When the raw grayscale image data is adjusted according to a preselected gamma curve before using that data to drive the pixels, the high and low ranges may be selected according to how well the gamma curve corrects the raw grayscale image data within the ranges.

摘要： A technique for improving the spatial and/or temporal uniformity of a light-emitting display by providing a faster calibration of reference current sources and reducing the noise effect by improving the dynamic range, despite instability and non-uniformity of the transistor devices. A calibration circuit for a display panel having an active area having a plurality of light emitting devices arranged on a substrate, and a peripheral area of the display panel separate from the active area is provided. The calibration circuit includes a first row of calibration current source or sink circuits and a second row of calibration current source or sink circuits. A first calibration control line is configured to cause the first row of calibration current source or sink circuits to calibrate the display panel with a bias current while the second row of calibration current source or sink circuits is being calibrated by a reference current. A second calibration control line is configured to cause the second row of calibration current source or sink circuits to calibrate the display panel with the bias current while the first row of calibration current source or sink circuits is being calibrated by the reference current.
