Meyer Burger ships an inkjet+PECVD OLED encapsulation system to an Asian customer

Jan 06, 2017

Meyer Burger announced that it has shipped a CONx TFE OLED thin film encapsulation system to an Asian customer. This system includes two deposition technologies, inkjet printing and PECVD to offer a complete encapsulation solution for flexible OLEDS.

The CONx TFE system compreses of Meyer Burger's proprietary remote plasma PECVD for inorganic coating and its PiXDRO inkjet printing technology for the deposition of accurately positioned and homogeneous organic layers. Meyer Burger says that the system provides excellent water and oxygen barrier properties without compromising the optical transparency of the encapsulation layer all the while operating at low temperatures and low ion bombardment.

Researchers develop a cheap and efficient MgO-based OLED encapsulation layer

Nov 11, 2016

Researchers from South China University of Technology (SCUT) demonstrated a new MgO-based OLED encapsulation layer. The researchers say that MgO provides an efficient barrier at a low cost, and can be deposited in low temperatures.

The researchers say that this is the first time that MgO is used for OLED encapsulation, but this material has a number of advantages - a low refractive index, a wide bandgap, high dielectric constant, high chemical stability and the lack of UV irradiation treatment requirements.

Veeco significantly reduces its ALD investments

Nov 02, 2016

Veeco logoIn September 2013, Veeco acquired Synos Technology for $185 million for the company's FAST-ALD flexible OLED encapsulation technology. Veeco did received a purchase order from SDC for a first-generation FAST-ALD prototype system, but the significant orders Veeco hopes to achieve never materialized.

In early 2015 Veeco announced that they do not see near-term revenue coming from this sector. Yesterday Veeco decided to significantly reduce future investments in its ALD technology development. Veeco says that some "competitive technologies" solved the display makers problems and it now sees ALD business pushed back two or three years.

Both Samsung and LG to switch to ALD for in-organic TFE?

Sep 24, 2016

A few days ago we reported that Kateeva says it has taken a "commanding lead" in the OLED thin film encapsulation (TFE) market with its ink-jet based systems. Kateeva's ink-jet printers are used to deposit organic materials, but the full TFE stack also contains in-organic materials.

Currently both LG and Samsung producers are using PECVD to deposit the in-organic materials, but according to a report from ETNEws, both Korean display makers are thinking about switching to ALD. Several companies, including Jusung Engineering, WONIK IPS, AP Systems and TES has ALD-based encapsulation deposition systems ready to be used in display production. Both LG and Samsung have finished with R&D work on ALD technology and are ready to introduce commercial systems into their production lines.

Kateeva says it takes a commanding lead in the OLED TFE market

Sep 22, 2016

OLED ink-jet developer Kateeva started to offer ink-jet based encapsulation systems in 2014, used to protect flexible OLED panels. Kateeva's encapsulation performance is excellent and it was already reported tha/t these systems are used in flexible OLED mass production - and today Kateeva announced that it takes a "commanding lead" in the OLED thin-film encapsulation (TEF) market.

Kateeva further says that it secured the "vast majority" of available TFE orders, and its customers include the world's largest flat-panel display makers in three key Asia regions - which probably includes Korea and China - and the third region is either Taiwan or Japan.

Smithers Apex sees the barrier films for printed electronics market growing at CAGR of 25%

Sep 01, 2016

Smithers Apex released a new report (Future of High-Barrier Films and Coatings for Printed Electronics to 2021) in which they see the global barrier film (encapsulation) market growing from $61.2 million in 2016 to $192.4 million in 2021 - a CAGR of 25%.

OLED display is the largest application for barrier films. In 2016, small rigid OLED displays barrier films were worth $16 million. Looking forward, small flexible OLEDs will be where growth will come from.

Encapsulix announces a new 200 mm ALD system for flexible OLED encapsulation

Jul 27, 2016

Encapsulix logoALD equipment maker Encapsulix developed a new ALD system (the Infinity 200) that is optimized for deposition on 200 mm substrates - for both R&D or manufacturing systems. The new system offers several advanced features especially suited for thin-film low-temperature encapsulation deposition on flexible substrates, particular for OLED displays.

Encapsulix announced that the new system was successfully installed and qualified for ultrafast OLED encapsulation at Leti, the CEA Tech research institute in Grenoble, France. Additional systems will be delivered in the next 12 months to customers in Asia.

NHK developed a new inverted-OLED device which requires almost no encapsulation

Jul 08, 2016

In 2013, the Japan Broadcasting Corp (NHK) and Nippon Shokubai developed a new OLED structure called inverted OLED, or iOLED, that drastically improves oxygen and moisture resistances. The basic idea behind iOLED is to invert the structure between the electrodes of a bottom-emission OLED. The electrodes are based on an organic material (polyethyleneimine) and not Lithium-based like most electrodes.

In 2015, NHK demonstrated a full-color iOLED display that uses a film substrate. The company now demonstrated the same display - more than one year after it was fabricated - still working even though there is almost no encapsulation.

SAES Group further strengthens its encapsulation solutions portfolio for fully flexible electronic devices

Jun 07, 2016
The following is a sponsored post by the Saes Group

Leveraging on their unique, distinctive properties, OLEDs are enabling brand new lighting and display opportunities, giving rise to an entire portfolio of portable, fully conformable, feather-light and, possibly, low power high definition display devices.

Anyway, OLEDs are nowadays facing the same issues they had since the beginning: basically, OLED materials are extremely sensitive to oxidizing agents and, especially, to moisture. This requires encapsulation materials with exceptionally high barrier properties, and active fillers or getters, capable of absorbing water on a single molecule basis. The optimization of many functional properties in single encapsulating materials is a very complex materials science problem. The fact that OLED materials can also be very sensitive to heat or radiations, generates many process constraints as well.
