Patent number: 11251168Abstract: Over a flexible substrate are deposited stacked pixel layers including a bottom layer of LEDs forming blue pixels, a middle layer of LEDs forming green pixels, and a top layer of LEDs forming red pixels. Each LED die comprises an LED portion and an integrated transistor portion. Applying a voltage to a control terminal of the transistor portion energizes the LED portion. The pixels are substantially transparent, due to the LEDs being microscopic and the pixel areas being much larger, to allow light from the underlying layers to pass through. The three layers of pixels are aligned so that a combination of a single top red pixel, a single underlying green pixel, and a single underlying blue pixel form a single multi-color pixel. The different layers have transparent column and row lines.Type: GrantFiled: November 4, 2020Date of Patent: February 15, 2022Assignee: NthDegree Technologies Worldwide Inc.Inventors: William Johnstone Ray, Michael LeFebvre, Darin Wagner, Richard A.

Patent number: 10964665Abstract: 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.Type: GrantFiled: January 18, 2017Date of Patent: March 30, 2021Assignee: Nthdegree Technologies Worldwide, Inc.Inventors: William Johnstone Ray, Richard Austin Blanchard, Mark David Lowenthal, Bradley Steven Oraw

Patent number: 10510928Abstract: Printed micro-LEDs have a top metal anode electrode that is relatively tall and narrow and a bottom cathode electrode. After the LED ink is cured, the bottom electrodes are in electrical contact with a conductive layer on a substrate. The locations of the LEDs are random. A thin dielectric layer is then printed between the LEDs, and a thin conductive layer, such as a nano-wire layer, is then printed over the dielectric layer to contact the anode electrodes. The top conductive layer over the tall anode electrodes has bumps corresponding with the locations of the LEDs. An omniphobic liquid is then printed which only resides in the “low” areas of the top conductive layer between the bumps. Any optical material is then uniformly printed over the resulting surface. The printed optical material accumulates only on the bump areas by adhesion and surface tension, so is self-aligned with the individual LEDs.Type: GrantFiled: June 12, 2019Date of Patent: December 17, 2019Assignee: Nthdegree Technologies Worldwide Inc.Inventors: William Johnstone Ray, Richard A.

Patent number: 10497672Abstract: 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.Type: GrantFiled: October 6, 2017Date of Patent: December 3, 2019Assignee: Nthdegree Technologies Worldwide Inc.Inventors: William Johnstone Ray, Mark David Lowenthal, Richard Austin Blanchard, Lixin Zheng, Xiaorong Cai, Bradley S.

Patent number: 10412833Abstract: A programmable circuit includes an array of printed groups of microscopic transistors or diodes having pn junctions. The devices are pre-formed and printed as an ink and cured. The devices have a proper orientation and a reverse orientation after settling on a conductor layer. The devices are connected in parallel within small groups. To neutralize the reverse-oriented devices, a sufficient voltage is applied across the parallel-connected diodes to forward bias only the devices having the reverse orientation. This causes a sufficient current to flow through each of the reverse-orientated devices to destroy an electrical interface between an electrode of the devices and the conductor layer to create an open circuit, such that those devices do not affect a rectifying function of the devices in the group having the proper orientation. An interconnection conductor pattern may then interconnect the groups to form complex logic circuits.Type: GrantFiled: September 19, 2018Date of Patent: September 10, 2019Assignee: Nthdegree Technologies Worldwide Inc.Inventors: Richard Austin Blanchard, William Johnstone Ray
