Abstract: A printable-component structure includes a carrier substrate, a bonding layer disposed on the carrier substrate, a solid weak-adhesion layer disposed on at least a portion of the bonding layer, at least a portion of a component disposed directly on and in contact with at least a portion of the weak-adhesion layer, and a release layer disposed in contact with at least a portion of the component. The component is adhered to the weak-adhesion layer with a force that is less than the adhesion between the component and a stamp, such as a PDMS stamp. The component can include a protruding post in sole contact with the weak-adhesion layer.

Abstract: An electrical conductor structure comprises a substrate and an electrical conductor disposed on or in the substrate. The electrical conductor comprises a first layer and a second layer disposed on a side of the first layer opposite the substrate. The first layer comprises a first electrical conductor that forms a non-conductive layer on a surface of the first electrical conductor when exposed to air and the second layer comprising a second electrical conductor that does not form a non-conductive layer on a surface of the second electrical conductor when exposed to air. A component comprises a connection post that is electrically connected to the second layer and the electrical conductor. The first and second layers can be inorganic. The first layer can comprise a metal such as aluminum and the second layer can comprise an electrically conductive metal oxide such as indium tin oxide.

Abstract: A method of making a surface-mountable pixel engine package comprises providing an array of spaced-apart conductive pillars and an insulating mold compound laterally disposed between the conductive pillars on a substrate together defining a planarized surface. Pixel engines comprising connection posts are printed to the conductive pillars so that each of the connection posts is in electrical contact with one of the conductive pillars. The pixel engines are tested to determine known-good pixel engines. An optically clear mold compound is provided over the planarized surface and tested pixel engines. Optically clear mold compound is adhered to a tape and the substrate is removed. The optically clear mold compound, the insulating mold compound, the conductive pillars, the optically clear mold compound, and the tested pixel engines are singulated to provide pixel packages that comprise the pixel engines and the known-good pixel engines are transferred to a reel or tray.

Abstract: An electro-optically controlled active-matrix system comprises a system substrate, row wires extending in a row direction disposed on the system substrate, a row controller providing a row electrical signal to each row wire, column light-pipes extending in a column direction disposed on the system substrate, a column controller providing a column optical signal to each column light-pipe, and pixels disposed over the system substrate. Each pixel can comprise a pixel circuit that is uniquely responsive to a row wire and to a column light-pipe, the pixel circuit receiving the row electrical signal from the row wire and receiving the column optical signal from the column light-pipe. In some embodiments, column wires carrying column electrical signals extend in a column direction over the system substrate and the pixel circuit is capacitively coupled to the row wire, the column wire, or both.

Abstract: A tiled display structure comprises a screen support having a screen emitter side and an opposing screen back side. A black matrix comprises a patterned layer of black-matrix material disposed on the screen back side, the pattern defining pixel openings that are substantially devoid of black-matrix material. An array of tiles comprises tiles each having a tile substrate and a plurality of pixels disposed in or on the tile substrate. Each pixel comprises one or more light emitters. The one or more light emitters are each disposed to emit light through a pixel opening in the black matrix. A substantially transparent adhesive layer adheres the array of tiles to the black-matrix material.

Abstract: A pulse-density-modulation display and image capture system comprises a display comprising a plurality of pixels. Each pixel comprises a light emitter that controllably emits light at a constant current for a variable amount of time and a control circuit connected to the light emitter to control the light emitter to emit light in response to an input signal specifying the desired luminance of the light emitter. The control circuit converts the input signal to a non-contiguous pulse-density-modulation signal and controls the light emitter to emit light in response to the non-contiguous pulse-density-modulation signal with a temporally variable constant-current control signal. Each pixel emits light responsive to a display timing signal. The pulse-density-modulation display and image capture system also comprises a sampling camera that records the pixels and is responsive to a camera timing signal different from the display timing signal.

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.
