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.

Thin Film Transistors: Eliminating the Roadblock to the Next Generation of Displays

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.

OLEDs in Lighting: Status and Trends

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.

Market Leading Wide Color Gamut, Narrow Band Phosphors by GE & Path Towards Enabling Next Generation Displays

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.

Flexible Displays: Key Emerging Trends and reliability challenges

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.

Fundamental Challenges in Micro LED Display Technology

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.
