Sigmaintell estimates that LG Display shipped 1.2 million smartphone AMOLED panels. LGD is currently shipping a single smartphone AMOLED panel, a 6" 1440x2880 (537 PPI) one used in LG's own V30 and Google's Pixel 2 XL. Reviewers and consumers alike were disappointed in LG's AMOLED performance.

Solar-Tectic developed a new OLED backplane technology to bridge the gap between IGZO and LTPS

US-based Solar-Tectic has launched a new low-temperature OLED backplane technology that could replace LTPS in future high-end mobile OLED displays and bridge the performance gap between IGZO and LTPS.

Solar-Tectic process, called LT1CS (Low temperature single crystal silicon) is a silicon based technology that creates highly oriented c-axis aligned or "textured" silicon crystals. Solar-Tectic says that the performance of LT1CS backplanes will be higher than IGZO performance. The company says that process is similar to SEL's CAAC-IGZO only based on silicon and not IGZO.

The EU SOLEDLIGHT project developed solution-processed R2R OLEDs, reports interim results

The SOLEDLIGHT (Solution Processed OLEDs for Lighting) project was launched in 2015 by a European consortium with an aim to develop cost efficient, roll-to roll (R2R) solution processed OLEDs, including their integration in prototype multiple-panel OLED lighting systems and luminaires.

The SOLEDLIGHT consortium (which is coordinated by the University of Valencia and includes OSRAM and Solvay) reported that it managed to develop multi-layer R2R solution processed OLEDs that achieved a power efficiency of 20 lm/W. This is still not up to par with evaporation-based OLEDs, but the project partners aim to achieve 100 lm/W (and 15,000 hours) by the end of 2017.

DSCC: OLED materials to grow at a 20% CAGR to reach $2.25 billion in 2022

DSCC released a new market report which tracks the OLED materials market. According to DSCC's estimates, the OLED material revenues will reach $905 million in 2017 and will grow at a 20% CAGR to reach $2.25 billion in 2022. Note that these numbers do not include royalty payments.

OLED Materials sales forecast (DSCC 2016-2022)

DSCC sees the small/medium display materials growing at a 22% (from $586 million in 2017 to $1.56 billion in 2022) - and growing faster than OLED TV materials (CAGR 16%) as ink jet printing, which will begin to be adopted in 2020 will result in more efficient OLED deposition.

Visionox demonstrates new OLED panels and flexible OLED prototypes

Visionox participated at the 19th China International Hi-Tech Fair opened in Shenzhen, and the company demonstrated several new OLED prototype panels. Visionox demonstrate several "full-screen" AMOLEDs, including a 6.01" one and a 5.99" flexible one.

According to the Chinese report, Visionox has stated its flexible OLED "roadmap" as the company wants to start with curved panels, then move to foldable and finally to stretchable displays. Visionox says it has achieved mass production technology for curved OLEDs, but according to our information its first flexible AMOLED fab will only begin production in the summer of 2018.

The Holst Centre developed and demonstrated a new barrier for foldable OLEDs

The Holst Centre is demonstrating a new optimized encapsulation (barrier) layer for foldable OLED panels. The new barrier is made from an organic layer sandwiched between two layers of silicon nitride (SiN). These are standard materials, but by optimizing the stack design the researchers at the Holst Centre were able to control its mechanical properties and create a much more flexible barrier.

The Holst researchers used an organic material that can withstand 400 °C and can be applied by slot-die coating. This allows the SiN layers to be deposited at 350 °C, improving their quality and ability to prevent water penetration. The Holst tested the OLED prototypes that use the new barrier for 1,000 hours (in accelerated lifetime testing) and no black spots appeared, even after 10,000 folding cycles (bending radiud 0.5 mm).
