The development of microLED displays has driven the need for high throughput and cost effective technologies for microLED mass transfer and integration, as conventional assembly technologies fail to provide the required accuracy and throughput. Building upon an extensive track record in the development of laser-assisted technologies for high resolution printing of multilayer circuits and fine pitch interconnects, Holst Centre has recently demonstrated selective and high-throughput laser die transfer of 40 μm microcomponents and high-throughput printing of 30 μm dots of conductive adhesive. In this talk, we will explain how Holst Centre’s technologies are promising key enablers for microLED displays.

In AR and VR applications the displays just don’t have enough brightness. For the next generation of computing AR/VR devices, high brightness, high speed nausea-free, high contrast and often high resolution microdisplays are sought by everyone from Consumer, Military, Medical and Industrial customers. The team at eMagin found the answer, we invented direct patterned OLED technology (dPd) that yields the highest brightness OLED microdisplays. We will combine dPd with additional structures to continue the improvement. These displays have been demonstrated, shipped in small volumes and will be designed into some of the most exciting AR/VR platforms. The speaker will discuss the journey, the results and the possibilities with this new technology, including its potential impact on today’s mobile devices.

iBeam Materials is developing a revolutionary new technology to make paper-thin, ultra-flexible and robust microLED displays. The display products are enabled by the ability to make large area flexible sheets of LED epi at low cost. The sheets of LEDs, produced by roll-to-roll manufacturing, will allow large-area monolithic integration of LEDs and active transistor devices in a single device sheet. MicroLEDs made on these robust sheets of thin metal foil will enable super-bright and power efficient displays not achievable today.

Optomec’s Aerosol Jet technology has a unique solution to enable panel front to backside connections without glass vias or vacuum processes. Aerosol Jet’s ability to print at high resolution, down to 10 μm, and at a high aspect ratio, as high as 5mm from the substrate regardless of topology, make it the ideal solution for both manufacturing and repair of metallization on glass edges. Demonstration of high speed, high density printing of connections from the front side of a panel to the backside will be shown along with repair of existing metallization created by other methods.

Display production has been a central focus of the printed electronics community. Cost pressure make it a perfect target for economic printing technologies like inkjet. However, in view of the ambitious goals, inkjet technology is cornered by challenges it was not designed to resolve. Above all, its printing resolution, traditionally only judged by the human eye, is simply unsuitable to meet most targets of the display industry. Electrohydrodynamic printing represents an avenue to resolve this issue and Scrona present the first printhead that combines the force of EHD with a truly scalable nozzle platform, to also bring along economics.

We are developing a new manufacturing process which aims to assemble millions of heterogeneous microchips (LEDs, sensors, electronics) into next generation display and lighting systems with the deterministic control of pick and place at the low cost of printing. The process starts with chiplets from standard processes, as no special coatings or shapes are needed. The system then uses programmable directed electrostatic assembly, parallel closed loop and open loop feedback control, and integrated continuous roller-based transfer of the assemblies to a final substrate for electrical interconnects.

Manufacturing cost is the highest risk for µLED displays. µLED display cost is composed of backplane and frontplane costs. Backplane cost may be similar to OLED displays. The major cost contributors for frontplane are epitaxy, transfer, and defect management. Here, the technology requirements for manufacturing high performance, cost-effective µLED displays are discussed.

Despite the great success of OLEDs in displays, the technology has struggled to establish a substantial presence in general lighting, mainly because of the high cost. Market progress was hindered by the offering of inferior products by some large international companies, who made major investments in large factories before the market and manufacturing technology were ready. The product quality has been improved substantially over the past two years, in both performance and reliability. Routes to market penetration have been identified, some of which will bring products that combine elements of lighting and displays. But even for such markets, new manufacturing techniques will be required to reduce costs and enable high volume production of some of the exciting prototypes that have emerged from research laboratories.

Long hailed as the “ultimate display technology,” Electroluminescent Quantum Dot LED (EL-QLED) devices have now been studied for over two decades, but they have yet to find commercial success in the display industry. Historically the focus has been on CdSe-based materials, but more recently InP, ZnTeSe, and perovskites have made impressive gains in efficiency and lifetime. This talk will provide an update on state-of-the-art EL-QLED for display and what technical hurdles remain. Finally I will provide insight as to the direction this important technology could take to achieve commercial success.

Walk into your local electronics store and the red color emitting from many of the displays will be GE phosphor technology. Since first being introduced into the display industry in 2014, the red-line emission of K2SiF6:Mn4+phosphor (PFS/KSF) centered at 631 nm has become the market leading wide color gamut solution for 4K UHD TVs, tablets, phones, monitors and laptops. KSF provides a cost effective, on-chip LED solution for wide color gamut displays that is a RoHS compliant, drop-in replacement in LCD BLUs without the need for barrier encapsulants to achieve excellent reliability. This presentation will discuss the technology that has enabled this success and the path forward around integration into future displays with higher color gamut and additional functionality (minileds, remote films, microleds) versus current HDR 4K/8K displays. An update on GE’s efforts around narrow-band green phosphor development will also be presented.

This presentation reviews two of META’s key technology development strands: metaOPTIX™ holographic optical technology and NanoWeb® transparent conductive nanostructures
metaOPTIX™ holographic optical components are fabricated on META’s Holography platform. Interference patterns are recorded with a laser into a light-sensitive photopolymer material to form Volume Holographic Gratings (VHGs), which transmit or reflect light in various ways, depending on the geometric structure of the recorded pattern.
NANOWEB® is a transparent conductor made of an invisible metal mesh that can be fabricated onto any glass or plastic surface. It offers a superior alternative to Indium Tin Oxide (ITO), Silver Nanowire (AgNW), graphene and carbon nanotube among other ITO-alternative technologies.

On the path to a new generation of display performance and manufacturability, a roadblock appeared: TFT technology. The display industry chose improving semiconductor material performance to break through the roadblock. This path has largely failed; it has provided about one-third of the required advance. Amorphyx leverages Moore’s Law in advancing TFT technology. Amorphyx’s technologies use amorphous metals-based materials to re-engineer the TFT and enable quantum tunneling to eliminate semiconductor materials. These innovations set a new path: fast, flexible and simple thin film electronics.
