Fraunhofer FEP develops a high-accuracy fingerprint sensor based on its bi-directional OLED microdisplays

May 04, 2017

The Fraunhofer FEP institute in Germany first unveiled its bi-directional OLED microdisplays in 2012 with the novel idea of embedding photo detectors between the OLED pixels. Since then the instituted demonstrated its second-generation microdisplay that supported a resolution of 800x600 (SVGA), up from VGA in the first generation prototypes.

The Fraunhofer FEP now announced that it developed a new generation of these displays, that employ an extra-think encapsulation layer, which can turn these new displays into fingerprint sensors. The idea is that the OLED display illuminates the fingers and then the reflected light is used to detect and analyze the fingerprint with excellent accuracy.

Kateeva doubles its manufacturing space in order to meet the demand for its OLED inkjet systems

Mar 09, 2017

OLED ink-jet developer Kateeva announced that it expanded its headquarters in silicon valley - in fact it doubled its manufacturing space in order to meet the demand for its inkjet systems.

IHS sees the OLED production equipment market reaching $9.5 billion in 2017

Feb 10, 2017

IHS says that the OLED industry is now entering a huge capacity-growth phase, and IHS estimates that the AMOLED production equipment market will reach $9.5 billion in revenues in 2017.

Almost half of that amount will go to TFT backplane equipment ($4.4 billion in 2017), while the organic layer deposition market will reach 2.2 billion and the encapsulation tools market will reach $1.2 billion. IHS estimates that Canon Tokki is the leader in OLED deposition equipment, and has a market share of over 50%.

The DoE grants two new SBIR OLED lighting projects

Jan 26, 2017

The US Department of Energy (DoE) announced new SBIR and STTR grants for solid state lighting projects. The DoE announced five new grants out of which two are related to OLED technologies.

Pixelligent Technologies were awarded an SBIR project titled "Light Extraction for OLED Lighting with 3-D Gradient Index". This project will explore the application of a novel and unique 3D gradient index (GRIN) layer to improve the efficiency and lifetime of OLED devices. Using such a unique structure, OLEDs could be produced that achieve the theoretical maximum extraction efficiency.

Encapsulix to supply ALD-TFE equipment to a leading Asian AMOLED producer

Jan 23, 2017

Encapsulix logoALD equipment maker Encapsulix announced that a leading Asian AMOLED manufacturer has chosen its ALD-TFE deposition systems, to be used as flexible AMOLED encapsulation. The first tool is already under construction and will start operating in the spring of 2017.

Encapsulix says that the order was awarded following an extensive evaluation of available ALD platforms, and this confirms the technological superiority and leading cost-of-ownership of the company's ALD-TFE equipment.

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

In 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.
