Abstract: A micro-transfer color-filter device comprises a color filter, an electrical conductor disposed in contact with the color filter, and at least a portion of a color-filter tether attached to the color filter or structures formed in contact with the color filter. In certain embodiments, a color filter is a variable color filter electrically controlled through one or more electrodes and can be responsive to heat, electrical current, or an electrical field to modify its optical properties, such as color, transparency, absorption, or reflection. In certain embodiments, A color-filter device includes connection posts and can be provided in or on a source wafer suitable for micro-transfer printing. In some embodiments, a color-filter device is disposed on a device substrate and can include a control circuit for controlling the color filter. An array of micro-transfer color-filter devices can be disposed on a display substrate in order to form a display.

Abstract: A printed electrical connection structure includes a substrate having one or more electrical connection pads and a micro-transfer printed component having one or more connection posts. Each connection post is in electrical contact with a connection pad. A resin is disposed between and in contact with the substrate and the component. The resin has a reflow temperature less than a cure temperature. The resin repeatedly flows at the reflow temperature when temperature-cycled between an operating temperature and the reflow temperature but does not flow after the resin is exposed to a cure temperature. A solder can be disposed on the connection post or the connection pad. After printing and reflow, the component can be tested and, if the component fails, another component is micro-transfer printed to the substrate, the resin is reflowed again, the other component is tested and, if it passes the test, the resin is finally cured.

Abstract: An optical power transfer device includes a transmitter circuit, including a laser light source that is configured to emit coherent light responsive to operation above a lasing threshold, and is configured to emit incoherent light responsive operation below the lasing threshold. A proximity sensor circuit is coupled to the transmitter circuit and is configured to output a detection signal therefrom responsive to authentication of an optical receiver including at least one photovoltaic cell having surface area of about 4 square millimeters or less within a proximity thereof. The transmitter circuit is configured to operate the laser light source below the lasing threshold to emit the incoherent light responsive to an absence of the detection signal from the proximity sensor circuit. Related devices and methods of operation are also discussed.

Abstract: A small-aperture-ratio display includes a display substrate and a plurality of spatially separated pixel elements distributed over the display substrate. Each pixel element includes one or more light emitters. An active electrical component is electrically connected to each of the pixel elements and each active electrical component is located on the display substrate at least partly between the pixel elements. The display substrate has a contiguous display substrate area that includes the pixel elements, the light emitters each have a light-emissive area, and the substrate area is greater than or equal to one-quarter the combined light-emissive areas of the light emitters.

Abstract: A matrix-addressed system includes a system substrate and an array of pixels arranged in rows and columns disposed on the system substrate. A column-control circuit provides information to or receives information from the pixels. The column-control circuit includes a separate column-driver circuit connected to each column of pixels that provides information in common to all of the pixels in the column or receives information in common from all of the pixels in the column. A row-select circuit likewise disposed on the system substrate includes a serial shift register having a number of row storage elements equal to or larger than the number of rows in the array of pixels. Each row storage element in the shift register has a row-select line connected to all of the pixels in a row.

Abstract: A printable electronic component includes a component substrate and a circuit disposed in or on the component substrate. One or more electrically conductive connection posts protrude from the component substrate. One or more electrically conductive component contact pads are exposed on or over the component substrate on a side of the component substrate opposite the one or more connection posts. The one or more component contact pads and the one or more electrically conductive connection posts are both electrically connected to the circuit. The components can be printed onto a destination substrate and electrically connected to contact pads on the destination substrate through the connection posts. The components can also be printed onto other components and electrically connected through the connection posts and component contact pads to form a three-dimensional electronic structure.
