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.

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.

Bio

After completing the Material Engineering studies in 2004, Francesca decided to pursue the Academic career by undertaking a PhD in Material Science and Engineering, with main focus on nano and bio technologies. In parallel established a 5 years collaboration with the Dentistry Department in order to increase the knowledge and awareness about dental materials in this sector.
In 2008 decided to leave the Academic path to jump into the entrepreneurial adventure and joining full-time the start-up Genefinity, a spin-off of the University of Trieste, which she founded in 2005 together with 3 other PhD colleagues. The company grew successfully for about 10 years by developing specific competences on thin films depositions, mainly PVD and ALD techniques, with main markets biomedical, food, solar and cosmetic.
In 2016, decided to jump into a new adventure and joined Applied Materials Italy as Business Developer, with the main target to expand the current solar market to other sector of the printed electronics.

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.

Bistable reflective displays are an alternative to traditional emissive and transmissive displays where power consumption and outdoor readability are paramount. Bodle has developed a new type of bistable reflective display technology based on solid state phase change materials (PCM). The presentation will focus on the fundamental aspect of the technology and its performance in terms of colour gamut, reflectivity and switching speed.

The presentation addresses the state of the display industry's Crystal Cycle and the impact of COVID-19 on display applications, then addresses the battle in the TV market for leadership among both brands and technologies. Samsung and TCL lead an LCD camp promoting quantum dot enhancement film (QDEF), while LG and Sony lead an OLED camp with LG Display's White-OLED technology. The presentation covers market data by technology and brand, and cost analysis of a range of advanced TV technologies, plus a forecast of displays and TVs by technology.
