  • Patent number: 10964665
    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. The devices in each group are connected in parallel so that each group acts as a single device. In one embodiment, about 10 devices are contained in each group so the redundancy makes each group very reliable. 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.

  • Patent number: 10497672
    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.
