Abstract: A printed energy storage device includes a first electrode, a second electrode, and a separator between the first and the second electrode. At least one of the first electrode, the second electrode, and the separator includes frustules, for example of diatoms. The frustules may have a uniform or substantially uniform property or attribute such as shape, dimension, and/or porosity. A property or attribute of the frustules can also be modified by applying or forming a surface modifying structure and/or material to a surface of the frustules. The frustules may include multiple materials. A membrane for an energy storage device includes frustules. An ink for a printed film includes frustules.

Abstract: A light emitting structure uses an extruded mixture of a fluorescent material and a transparent plastic to form a thin flexible substrate. The extrusion, using a slot die, forms a thin flexible film having very smooth surfaces with a uniform thickness. A transparent first conductive layer is then printed over the substrate. Pre-formed micro-LEDs are then printed over the first conductive layer, where the bottom electrodes of the LEDs contact the first conductive layer. A dielectric layer is deposited between the LEDs and exposes the top electrode of the LEDs. A second conductive layer, which may be transparent or reflective, is printed over the LEDs to electrically connect at least some of the LEDs in parallel. Primary light emitted from the LEDs energizes the fluorescent material in the substrate to emit secondary light from the substrate. Blue LED light may combine with the secondary light to create a wide gamut of colors, such as white.

Abstract: An LED sticker is disclosed that receives an NFC transmission from a nearby smartphone to energize LEDs in the sticker. A spiral (or loop) antenna is used in the sticker to generate power from the NFC transmission. The NFC signal is at 13.56 MHz, which is the resonant frequency of the NFC antenna circuit in the smartphone. The LED portion is formed by sandwiching pre-formed microscopic LEDs between two conductive layers to connect the LEDs in parallel. The conductive layers form a relatively large integral capacitor that is used to achieve the 13.56 MHz resonant frequency. So no additional capacitor is needed in the circuit to achieve a resonance of 13.56 MHz. This greatly reduces the design requirements of the antenna. The LED sticker may also contain an NFC tag having its own independent loop antenna and NFC chip. Various practical applications of the LED sticker are disclosed.

Abstract: The present invention provides an electronic apparatus, such as a lighting device comprised of light emitting diodes (LEDs) or a power generating apparatus comprising photovoltaic diodes, which may be created through a printing process, using a semiconductor or other substrate particle ink or suspension and using a lens particle ink or suspension. An exemplary apparatus comprises a base; at least one first conductor; a plurality of diodes coupled to the at least one first conductor; at least one second conductor coupled to the plurality of diodes; and a plurality of lenses suspended in a polymer deposited or attached over the diodes. The lenses and the suspending polymer have different indices of refraction. In some embodiments, the lenses and diodes are substantially spherical, and have a ratio of mean diameters or lengths between about 10:1 and 2:1. The diodes may be LEDs or photovoltaic diodes, and in some embodiments, have a junction formed at least partially as a hemispherical shell or cap.

Abstract: 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.

Abstract: 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.

Abstract: In one embodiment, a printed LED area comprises a random arrangement of printed LEDs and a wavelength conversion layer. The LED area is embedded in an object to be authenticated, such as a credit card or a casino chip. The object may include a light guide for enabling the generated light to be emitted from any portion of the object. In one embodiment, when the LEDs are energized during authentication of the object, the existence of light emitted by the object is sufficient authentication and/or provides feedback to the user that the object is being detected. For added security, the emitted spectrum vs. intensity and persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated.

Abstract: In one embodiment, a printed security mark comprises a random arrangement of printed LEDs and a wavelength conversion layer. During fabrication of the mark, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The emitted spectrum vs. intensity and persistence of the wavelength conversion layer is also encoded in the first code. The mark may be on a credit card, casino chip, banknote, passport, etc. to be authenticated. For authenticating the mark, the LEDs are energized and the dot pattern, spectrum vs. intensity, and persistence are converted into a code and compared to the first code stored in the database. If there is a match, the mark is authenticated.
