    摘要: A device source wafer includes a wafer substrate, devices formed on or in the wafer substrate at a location on the wafer substrate, and test structures disposed on the wafer substrate connected to some but not all of the devices. The devices include a first device disposed at a first location and a second device disposed at a second different location on the wafer substrate. The test structures include at least a first test structure connected to the first device and a second test structure connected to the second device. The first test structure is adapted to measuring a characteristic of the first device and the second test structure is adapted to measuring the characteristic of the second device. An estimated characteristic of unmeasured devices is derived from the first and second device locations and measured characteristics and the device is selected based on the estimated characteristic.

    摘要: A system with dimming control includes a luminance signal, a variable-frequency-clock signal generator responsive to the luminance signal operable to generate a variable-frequency clock signal, a pixel-control signal generator responsive to the variable-frequency clock signal operable to generate a pixel-control signal, and a pixel including a light emitter responsive to the pixel-control signal. The pixel-control signal can be a temporally modulated signal such as a pulse-width modulation signal or a pulse-density modulation signal. A display can comprise an array of pixels and a display controller. The pixel or the display controller can include the variable-frequency clock signal or the pixel-control signal generator, or both.

    摘要: A flat-panel display comprises a display substrate, an array of pixels distributed in rows and columns over the display substrate, the array having a column-control side, and column controller disposed on the column-control side of the array providing column data to the array of pixels through column-data lines. In some embodiments, rows of pixels in the array of pixels form row groups and each column of pixels in a row group receives column data through a separate column-data line. In some embodiments, each pixel in each column of pixels in the array of pixels is serially connected and each pixel in the array of pixels comprises a token-passing circuit for passing a token through the serially connected column of pixels.
