  • Publication number: 20180132347
    Abstract: A programmable circuit includes an array of printed groups of microscopic transistors or diodes. The devices are pre-formed and printed as an ink and cured. A patterned hydrophobic layer defines the locations of the printed dots of the devices. The devices in each group are connected in parallel so that each group acts as a single device. Each group has at least one electrical lead that terminates in a patch area on the substrate. An interconnection conductor pattern interconnects at least some of the leads of the groups in the patch area to create logic circuits for a customized application of the generic circuit. The groups may also be interconnected to be logic gates, and the gate leads terminate in the patch area. The interconnection conductor pattern then interconnects the gates for form complex logic circuits.

  • Publication number: 20180114775
    Abstract: Active LEDs have a control transistor in series with an LED and have a top electrode, a bottom electrode, and a control electrode. The active LEDs are microscopic and dispersed in an ink. A substrate has column lines, and the active LEDs are printed at various pixel locations so the bottom electrodes contact the column lines. A hydrophobic mask defines the pixel locations. Due to the printing process, there are different numbers of active LEDs in the various pixel locations. Row lines and control lines contact the top and control electrodes so that the active LEDs in each single pixel location are connected in parallel. If the LEDs emit blue light, red and green phosphors are printed over various pixel locations to create an ultra-thin color display. Any active LED may be addressed using row and column addressing, and the brightness may be controlled using the control lines.

  • Patent number: 9887425
    Abstract: A plurality of batteries is printed on a flexible substrate, where each battery may output the same voltage, such as about 1.5 volts. Batteries in a first subset are connectable in parallel by controllable switches to control the maximum current that can be delivered to a load. Batteries in a second subset are also connectable in parallel by additional controllable switches to control the maximum current that can be delivered to the load. Another group of switches can either connect the two subsets of batteries in series, to generate 3 volts, or connect the subsets in parallel to increase the maximum current. Additional subsets of batteries and their associated switches may be further connected to increase the voltage and current. The power supply may be standardized and configured by the user for a particular load, such as a sensor for a medical skin patch.

  • Patent number: 9526148
    Abstract: An exemplary system comprises a power regulator and an emitting apparatus. The emitting apparatus is typically attached to or integrated with a display object, such as a merchandise package or container. A support structure, such as a point of purchase display, typically contains or supports one or more power regulators and display objects. The power regulator comprises a controller and a primary inductor, and the controller is adapted to provide a voltage or current to the primary inductor to generate a first primary inductor voltage. The emitting apparatus comprises an illumination source and a secondary inductor coupled to the illumination source. The illumination source is adapted to emit visible light when the power regulator is in an on state and when the secondary inductor is within a predetermined distance of the primary inductor. In exemplary embodiments, the first and second inductors are substantially planar.

  • Patent number: 9490407
    Abstract: A flexible light sheet includes a bottom conductor layer overlying a flexible substrate. An array of vertical light emitting diodes (VLEDs) is printed as an ink over the bottom conductor layer so that bottom electrodes of the VLEDs electrically contact the bottom conductor layer. A top electrode of the VLEDs is formed of a first transparent conductor layer, and a temporary hydrophobic layer is formed over the first transparent conductor layer. A dielectric material is deposited between the VLEDs but is automatically de-wetted off the hydrophobic layer. The hydrophobic layer is then removed, and a second transparent conductor layer is deposited to electrically contact the top electrode of the VLEDs. The VLEDs can be made less than 10 microns in diameter since no top metal bump electrode is used. The VLEDs are illuminated by a voltage differential between the bottom conductor layer and the second transparent conductor layer.

  • Patent number: 9443180
    Abstract: In one embodiment, a security label comprises a random arrangement of printed LEDs. During fabrication of the label, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The label is then attached to an object to be later authenticated, or the LEDs are printed directly on the object, such as a passport, license, bank note, certificate, etc. For authenticating the object, the LEDs are energized and the dot pattern is converted into a code. The code is compared to the first code stored in the database. If there is a match, the object is authenticated. The label may also have a printed second code associated with the first code, and both codes must match codes stored in the database for authentication. The general shape of the printed pattern may convey the proper orientation of the pattern.
