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.

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.

OLED was once thought to be a sure winner for the next generation of high-end TVs. However, LCD keeps improving and closing the performance gap. Quantum Dots, already widespread in high end TVs are spreading into mid-range models. New technologies are emerging: miniLED backlights are used by most TV makers in their 2021 flagship models and the first QD-OLED panels should be available later in 2021. In the longer term, microLED, nanorod LEDs and ElectroLuminescent Quantum Dots (EL-QD) are all promising alternatives to OLEDs for TV applications. The talk will provide an overview of emerging TV technologies and discuss adoption trends, roadmaps and remaining roadblocks for each technology as well as improvement paths for OLED.

In 2007, Apple introduced the first smartphone based on LDC displays. These LDC displays have multiple rigid layers which add thickness to the product. Later on, glass OLED was introduced with fewer layers that could help to decrease the product thickness. Now with the help of plastic/flexible OLED curved edges are possible and now even different form factors like foldable and rollable products are in the market. Recently, foldable/flexible consumer electronic devices are becoming popular; however, the reliability of these devices are still not as mature as conventional (rigid) devices. With incorporating thin cover window film/glass for curved and foldable devices, new failure modes (Crease, delamination, buckling, scratches, low energy impact, …) have been highlighted and consequently new reliability tests should be defined to correctly assess the performance of foldable/flexible displays.

Out of Home (OOH) Advertising is a very old business that dates back to the time of the Egyptians. Pharaohs used obelisks to communicate and promote services to the public.

Lamar Advertising has worked with local and national customers to communicate and promote their products and services for over 119 years. The last 15 years have brought a surge in LED digital displays that allow for quick, dynamic content. At Lamar, we continue to look for innovation with improved LED displays and reflective display technology along with solar and battery systems to further develop our advertising displays.

Recently, Cd-free quantum dots (QDs) such as InP for green and red, and ZnSe for blue emission have gained a great amount of attention as electroluminescent (EL) or photoluminescent (PL) QD display applications due to their potential with good optical properties as an environmentally friendly alternative to Cd-based QDs. Our team has been working on QD technologies for over 10 years with various industry and governmentfunded projects. Here, the important progresses and current challenges on both EL and PL QD application will be discussed. Since the patterning technology of the QD layer is the most critical aspect for QD displays, the inkjet printing activity, the most promising technology for pixelation, on the QD layers including ESJET/EHDJET process will be also briefly introduced.
Our understanding of the fundamental design principles on not only Cd-free QD materials but also PL EL QD displays combining with their printing technologies can provide a new opportunity to overcome the challenges on the commercialization of QD display in the next-generation information display market.
