OLED-Info: the OLED experts

South Korea's Semes has finished the development of a 8-Gen (2500x2200 mm) QD inkjet printing system, and has begun to mass produced systems, aiming to ship these to Samsung Display.

The 8.5-Gen Vincent QD inkjet printing system utilizes over 100 print heads, and achieves a resolution of over 220 PPI. Semes says that it has improved the PPI by 30% compare to its previous systems.

Apple recently launched its iPhone 17e 'budget' smartphone, with a 6.1" 1200 nits (peak) 1170x2532 LTPS AMOLED display. According to a report from Korea, Apple ordered around 20 million OLED displays for the 17e, and Samsung Display will supply most of these panels.

In fact, The Elec estimates that Samsung will ship around 11 million panels, BOE 7.5 million, and LGD around 3.5 million, similar to the situation last year with the iPhone 16e.

AMOLED display producer Visionox provided an update on its pTSF OLED emitter material technology, that it has been developing for many years in collaboration with Tsinghua University since 2014.

pTSF, or Phosphorescence‑assisted Thermally activated Sensitized Fluorescence is an emitter platform that is based on a three materials, phosphorescence materials, TADF materials, and a fluorescent emitter. According to Visionox, this emitter system enables high power consumption, long lifetime, and a narrowband emission (to enable a wide color gamut display). 

Researchers from Korea's KAIST institute, in collaboration with colleagues from the University of Chicago and Suzhou University in China, have developed a new stretchable OLED electrode technology that enables higher performance under stretching conditions.

To enable this high performance (brightness) stretchable OLEDs, the researchers developed a hybrid liquid metal cathode. The electrode was deposited by stacking thin layers of liquid metal, and slight etching on the top layer. 

China-based Shaanxi Lighte Optoelectronics Material (LTOM) published its preliminary financial results for 2025, with a 17% increase in revenues to 552 million RMB ($80.2 million USD), and a 40% increase in its profits to $30 million.

LTOM says that in 2025 it benefited from the current trend within China-based OLED makers to increase their adoption of local materials, at the expense of imported materials from Korea, Japan and other countries.
