OLED-Info: the OLED experts

Researchers from Seoul National University, in collaboration with researchers from Drexel University have developed the world's most efficient (17% EQE) fully-stretchable OLED device, using an exciplex-assisted phosphorescent layer and MXene-contact stretchable electrodes.

In a fully stretchable OLED, all constituent layers exhibit intrinsic mechanical stretchability. Most reported stretchable displays rely on rigid light-emitting devices connected by stretchable interconnects, and these suffer from poor mechanical reliability at junctions under strain, limited skin conformability, and degradation in display resolution.

BCDTek says that it has successfully installed the first production equipment at its upcoming K3 OLED module production line in Fengcheng, Jiangxi Province.  BCDTEK is now starting trail production at the K3 line, and will hopefully ramp up production in the near future.

The K3 line produces two kinds of OLED modules - flexible AMOLED displays for consumer electronics and automotive applications, and OLED microdisplays for VR/AR applications.

Everdisplay (EDO) announced its preliminary 2025 financial results, saying that the company will report a growth of 10% in revenues, although it still suffers from an annual net loss. EDO will soon release its final and full 2025 results.

In the first three quarters of the year, EDO reported 4 billion Yuan ($574 million USD) in revenues, up 8.25% from the first three quarters of 2024. The net loss in the first three quarters was about $196 million.

Blue OLEDs remain one of the most critical, and challenging, components in modern display and lighting technologies. As device architectures grow more complex and performance targets become more demanding, traditional trial-and-error development is no longer sufficient. Leading OLED innovators are increasingly turning to multiscale simulation as a strategic tool to guide material selection, device design, and lifetime optimization.

Modeling and simulations are not replacing experiments, but are accelerators: enabling faster decisions, deeper insight, and reduced development risk. At Software for Chemistry & Materials (SCM), we develop and support the Amsterdam Modeling Suite (AMS) for atomistic simulations, and the 3D kinetic Monte Carlo (3D-KMC) code Bumblebee for advanced device-level modeling. With this toolkit, OLED researchers and device engineers can now connect molecular design choices directly to measurable device performance [1].

In our OLED history article series, we look back 20, 10, and 5 years ago, and revisit the history of the OLED industry. We hope these are articles are nostalgic, and fun - but also informative - by reflecting on the past, we can better understand how far the industry has come and where it is headed. 

The 2006 BenQ-Siemens S88, the world's first AMOLED phone

20 years ago - Q1 2006

In early 2006, OLED production was almost only simple passive-matrix displays (PMOLEDs), but we were starting to see an emergence of AMOLED production. In fact, in January 2006, phone maker BenQ-Siemens announced the world's first phone to use an AMOLED display, the S88, with its 2" 176x220 display produced by AUO. AUO continued to produce AMOLEDs at low quantities, but never managed to fully achieve real mass production.

Researchers from KAIST, led by Professor Yoo Seunghyup, developed a novel quasi-planar light extraction structure that enables to more than double the light output from OLED devices.

The researchers optimized the radiative power transfer in finite-sized OLED emission and reception areas, and then added a quasi-planar light extraction structure that has both a curved section and a straight section. Experiments have shown that this design minimized light loss caused by back-reflection within the structure and allowed more light to be emitted externally within a limited space.
