Abstract : The OLED came to attract attention as various information displays. JOLED started the production of middle-sized printed OLED display. We hope our RGB printing method brings an innovation for the display manufacturing and a dawn of the new display era.

Abstract : The flexible OLED market, which had been expected to grow rapidly due to the adoption of flexible OLEDs in iPhone X, is cooling down due to sluggish iPhone X sales.  The sluggish iPhone X sales of more than $1,000 may affect the foldable OLED smartphone, which is expected to be released at the end of the year. LG Display, which produces OLEDs for TVs, is asking for panel price hikes to escape the continuous loss.  UBI Research will analyze the various factors that affect OLED industry growth and forecast future OLED market.

Abstract : Organic Vapor Jet Printing (OVJP) is a solvent-less, mask-less printing technology for depositing patterned small molecule organic materials to manufacture large area side by side R-G-B OLED displays.

Commercial manufacture of large area (TV), side-by-side RGB OLED displays is currently challenged by lack of a suitable methodology for the patterned OLED deposition. Fine metal masks used for mobile OLED displays have not been proven to scale to greater than Gen 8, and scanning smaller shadow masks across a large area has not provided acceptable yield. Inkjet technology has been in development for many years and has yet to provide sufficient performance for volume manufacturing. Organic Vapor Jet Printing (OVJP) has been developed to print patterned OLED layers for large area displays, while avoiding issues arising from the use of fine metal masks and use of solvents.

Abstract : The OLED revolution is already well underway in the smartphone market, enabling new form factors, all screen displays, and thinner, lighter displays. The size of the worldwide OLED display market is expected to increase from $23.2 billion in 2017 to $62.8 billion in 2022, representing a five-year compound annual growth rate of 22.0% (DSCC, SID 2017). But the OLED revolution is just getting started. In the next decade, we expect that OLED technology will enable products which feature foldable and rollable displays, as well as large displays (TVs, signs) with superb contrast and color.

Advanced inkjet printing (IJP) is already playing a critical role in today’s OLED products.  Inkjet deposition printing has emerged as the leading deposition method currently operating for mass production of the organic TFE layer of mobile OLED displays. For the TFE process, IJP provided numerous technical and cost advantages over alternate organic film deposition techniques. Looking forward, IJP will continue to play a critical role in enabling the next two inflections in the OLED technology roadmap. For smartphone technology, we believe the next inflection is the foldable display, which will require improved TFE processes to achieve the lifetimes and yields required for mass production. Extending the current TFE process, including IJP for the critical organic interlayer, is the most likely path forward to meet the requirements of foldable displays.

We believe the next inflection in the TV technology roadmap is the mass production of RGB OLED TVs, which cannot be manufactured at low cost using conventional pixel patterning techniques used on small area displays. Advanced IJP is a promising candidate for cost-effective pixel patterning, and multiple display manufacturers are already doing evaluation of RGB IJP technology in their R&D lines.

This presentation will address the application of Kateeva’s advanced IJP technology to the manufacturing of current and future OLED displays.

Abstract : We will present the latest status of high performance OLED material development based on our conjugated polymer technology. We also show the comparison of the performance between ink-jet (IJ) and spin devices, and its theoretical fundamentals to obtain high performance in IJ printing.

Abstract : Optically clear adhesives (OCA) have been used for more than a decade to bond rigid LCD and AMOLED displays for consumer electronics applications, offering optical, mechanical and electrical performance benefits. The performance requirements of an OCA to bond cover window, touch sensors, and circular polarizers in a plastic OLED display to bent coverglass or a flexible, foldable OLED display are drastically different from a flat, rigid device.

Abstract :Thin-film encapsulation(TFE) using the Vitex multilayer technology with the implementation of three or less dyads is one of the most potent methods to ensure for protection from moisture and Oxygen penetration in OLED Devices. This is the origin to start Ink material applied to the organic layers as a proven evidence of Vitex System.

However, OLED thin film encapsulation technology is the one of technologies emerging as the core technology of flexible OLED, and More of Ink technology development & Solutions are required from conventional organic Ink base such as Flexibility, Dimensional Stability, High purity with low outgas generation. This brings Silicone nature to be candidate as a reliable TFE structure.

In this presentation, Momentive’s patented InvisiSil® AM2046series offers high performance with high reliable Silicone base Ink material solution for Flexible OLED TFE Interlayer Structure.

Abstract : As the market for flexible OLED devices grows, Corning’s high-performance display glass – Corning Lotus™ NXT Glass – answers an important need in the manufacturing process as the industry’s leading carrier glass substrate.

Abstract :The AMOLED technology can nowadays be found in most of the high-end smartphone and premium TVs. The AMOLED displays show a superior picture quality with extremely high contrast ratio and brilliant colors. Additionally, they can also be made flexible and bendable and therefore allow new shapes of applications.
Despite the increasing market share of OLEDs in mobile devices and TVs, some issues related to performance need further improvement, especially a reduction of the power consumption and an increase of the display resolution. Reducing the device power consumption requires energy-efficient and stable emitter materials for the basic RGB colors. While there are highly efficient red and green emitter materials commercially available, there are no efficient and stable blue OLED emitters on the market yet.
CYNORA is developing a new type of organic emitting materials for OLED displays based on TADF (Thermally Activated Delayed Fluorescence) technology. With this technology, CYNORA will be able to commercialize the first high-efficiency blue emitting material on the market, which is the most sought-after material by OLED display makers. High-performance blue materials will enable a significant reduction of the power consumption and allow a higher display resolution.
The interest in these new highly efficient TADF emitters by CYNORA was lately confirmed by an investment from LG Display and Samsung Ventures in said company.
In this talk we will present our recent progress on blue TADF emitters and the latest material performance, which is already very close to commercial fluorescent emitters. Additionally, we will discuss, next steps towards the coming commercialization and the mass production of CYNORA’s blue TADF emitters for AMOLED displays. First AMOLEDs with high-efficiency blue TADF emitters are expected in 2019.
