Abstract: 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.

Abstract: A method of printing comprises providing a component source wafer comprising components, a transfer device, and a patterned substrate. The patterned substrate comprises substrate posts that extend from a surface of the patterned substrate. Components are picked up from the component source wafer by adhering the components to the transfer device. One or more of the picked-up components are printed to the patterned substrate by disposing each of the one or more picked-up components onto one of the substrate posts, thereby providing one or more printed components in a printed structure.

Abstract: A white-light-emitting inorganic light-emitting-diode (iLED) structure comprises first iLEDs electrically connected in series, each first iLED emitting a different color of light from any other first iLED when electrical power is provided to the first iLEDs, and a second iLED electrically connected to one of the first iLEDs, the second iLED emitting the same color of light as the one of the first iLEDs when electrical power is provided to the first iLEDs. The second iLED can be electrically connected in series or in parallel with the one of the first iLEDs. Such iLED structures can be used at least in displays, lamps, and indicators.

Abstract: 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.

Abstract: An example of a pixel module comprises a module substrate having light emitters disposed on a light-emitter surface and a controller disposed on a controller surface opposed to the light-emitter surface. At least one module electrode is electrically connected to the controller and at least one module electrode is electrically connected to each light emitter. An example of a pixel-module wafer comprises a module source wafer comprising sacrificial portions and module anchors, each sacrificial portion laterally separated from an adjacent sacrificial portion by a module anchor and a pixel module disposed entirely over each sacrificial portion. At least one module tether physically connects each of the pixel modules to at least one of the module anchors. An example of a pixel-module display comprises a display substrate, pixel modules disposed on the display substrate and display electrodes disposed on the display substrate, each display electrode electrically connected to a module electrode.

Abstract: A display comprises a transparent polymer support, an array of light emitters embedded in the support, and a redistribution layer. Each light emitter comprises electrode contacts that are substantially coplanar with a back surface of the support and emits light through a front surface of the support opposite the back surface when provided with power through the electrode contacts. The redistribution layer comprises a dielectric layer that is disposed on and in contact with the support back surface and distribution contacts that extend through the dielectric layer. Each of the distribution contacts is electrically connected to an electrode contact and is at least partially exposed.

Abstract: 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.
