Abstract: A redundant pixel layout for a display comprises a display substrate and an array of pixels disposed on or over the display substrate. Each pixel comprises a first subpixel and a redundant second subpixel. The first subpixel includes a first subpixel controller electrically connected to controller wires and a first light emitter electrically connected to a first-light-emitter wire. The first light emitter is controlled by the first subpixel controller through the first-light-emitter wire. The second subpixel includes a second-subpixel-controller location connected to the controller wires and a second-light-emitter location comprising a second-light-emitter wire. The first light emitter is adjacent to the second-light-emitter location and the first light emitter and the second-light-emitter location are closer together than are any two pixels in the array of pixels.

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: An interpolated flat-panel display comprises a display substrate, pixel controllers disposed in a controller array over the display substrate, and pixels disposed in a pixel array over the display substrate. Each pixel controller is connected to one or more control lines and is operable to output pixel information. Each pixel is operable to emit light in response to pixel information received from a pixel controller. The pixel array is larger than the controller array, each pixel is connected to at least one pixel controller, and at least some pixels are interpolated pixels connected to at least two pixel controllers and are operable to emit light in response to pixel information received from the at least two pixel controllers.

Abstract: A multi-color LED display comprises pixels, each comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel comprises a first light-emitting diode (LED) that emits a first color of light, the second sub-pixel comprises second LEDs that emit a second color of light different from the first color of light, and the third sub-pixel comprises third LEDs that emit a third color of light different from the first color of light and different from the second color of light. The second LEDs are electrically connected in parallel and the third LEDs are electrically connected in series.

Abstract: An example of a method of making a printed structure comprises providing a destination substrate, contact pads disposed on the destination substrate, and a layer of adhesive disposed on the destination substrate. A stamp with a component adhered to the stamp is provided. The component comprises a stamp side in contact with the stamp and a post side opposite the stamp side, a circuit, and connection posts extending from the post side. Each of the connection posts is electrically connected to the circuit. The component is pressed into contact with the adhesive layer to adhere the component to the destination substrate and to form a printed structure having a volume defined between the component and the destination substrate. The stamp is removed and the printed structure is processed to fill or reduce the volume.

Abstract: A printed structure comprises a device comprising device electrical contacts disposed on a common side of the device and a substrate non-native to the device comprising substrate electrical contacts disposed on a surface of the substrate. At least one of the substrate electrical contacts has a rounded shape. The device electrical contacts are in physical and electrical contact with corresponding substrate electrical contacts. The substrate electrical contacts can comprise a polymer core coated with a patterned contact electrical conductor on a surface of the polymer core. A method of making polymer cores comprising patterning a polymer on the substrate and reflowing the patterned polymer to form one or more rounded shapes of the polymer and coating and then patterning the one or more rounded shapes with a conductive material.

Abstract: A therapeutic information display comprises an information signal, an array of pixels responsive to the information signal, each pixel in the array of pixels comprising one or more pixel light emitters responsive to the information signal to emit light, and a therapeutic-light emitter. The therapeutic-light emitter emits light having a wavelength in the range of 650 to 1000 nm. A therapeutic front light comprises a cover substrate disposed in relation to an information display and a therapeutic-light emitter disposed on or in the cover substrate, wherein the therapeutic-light emitter emits invisible light having a wavelength no greater than 1000 nm. A therapeutic window comprises a transparent sheet of material and a therapeutic-light emitter comprising one or more quantum dots or phosphors embedded in the transparent sheet of material. The therapeutic-light emitter emits invisible light having a wavelength no greater than 1000 nm.

Abstract: A method of making a display structure comprises providing a display substrate having a display surface, disposing components on and in contact with the display surface, uniformly blanket coating the display surface with a curable layer of uncured light-absorbing material, and curing the curable layer of uncured light-absorbing material to provide a layer of cured light-absorbing material so that the components project from the layer of cured light-absorbing material without having pattern-wise etched the layer of cured light-absorbing material after the light-absorbing material has been cured. The uniform blanket coating has a thickness greater than a thickness of the component, disposing the components comprises printing the components through the uniform blanket coating such that the components protrude from the uniform blanket coating, or the component is coated with a de-wetting material.
