Abstract:
A color-conversion structure includes an article comprising a color-conversion material disposed within a color-conversion layer. At least a portion of a tether is within or extends from the article. The color-conversion structure can be disposed over a sacrificial portion of a substrate to form a micro-transfer printable device and micro-transfer printed to a display substrate. The color-conversion structure can include an light-emitting diode or laser diode that is over or under the article. Alternatively, the article is located on a side of a display substrate opposite an inorganic light-emitting diode. A display includes an array of color-conversion structures disposed on a display substrate.
Abstract:
The present invention provides novel tank circuits that are totally passive, and they are made of conductive-grade carbon nanotubes (CNTs) on substrates, and preferably flexible substrates. These components and structures contain no traditional electronic materials such as silicon, metal oxides, or ceramics, and they are totally organic. They may be used in applications where the resonant frequency and amplitude of the sensor can be modulated by a thermal, mechanical, or chemical signal, such as temperature, strain, pressure, vibration, or humidity. All-organic, and consequently combustible, passive RF sensors have unique applications for defense and consumer industries.

An electronic assembly comprises a first circuit board with a first substrate having an inner side and an outer side opposite the inner side. A plurality of primary components are mounted on the inner side of the first circuit board. A frame (e.g., or heat-sinking spacer) is secured to the first circuit board. A second circuit board comprises a second substrate having an inner side and an outer side opposite the first side. The second circuit board is secured to the frame and separated from the first circuit board in at least one spatial dimension. At least one secondary component is mounted on the second circuit board. A first housing section is adapted for mating with a second housing section. The first housing section and the second housing section collectively enclose the first circuit board and the second circuit board.

A semiconductor package includes a metal baseplate, a semiconductor die having a reference terminal attached to the baseplate and an RF terminal facing away from the baseplate, and a multilayer circuit board having a first side attached to the baseplate and a second side facing away from the baseplate. The multilayer circuit board includes a plurality of interleaved signal and ground layers. One of the signal layers is at the second side of the multilayer circuit board and electrically connected to the RF terminal of the semiconductor die. One of the ground layers is at the first side of the multilayer circuit board and attached to the metal baseplate. Power distribution structures are formed in the signal layer at the second side of the multilayer circuit board. RF matching structures are formed in a different one of the signal layers than the power distribution structures.

An integrated electronic assembly including a first electronic component defining a receptacle and at least a second electronic component wherein at least a portion of the second electronic component is disposed in the receptacle of the first electronic component, and a method for conserving space in a circuit or on a printed circuit board by integrating a plurality of electronic components so that the plurality of electronic components collectively take up a smaller amount of space on a substrate than the plurality of electronic components would if the plurality of electronic components were not integrated.
Abstract:
The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.
Abstract:
A printed board includes: a base member; a recess portion provided in the base member; a heat dissipation member fitted into the recess portion; and a wiring pattern provided on an upper side of the base member and the heat dissipation member via an insulator. A contact portion in which an inner circumferential surface of the recess portion and an outer circumferential surface of the heat dissipation member contact each other and a separation portion in which those do contact each other are formed. A gap between the recess portion and the heat dissipation member is filled with thermosetting resin of the base member melted by heating. At least a partial portion in a width direction of the wiring pattern passes through a position vertically overlapping the separation portion while an entire portion thereof does not pass through a position vertically overlapping the contact portion.
