The end of the OLED process monoculture - what will it mean for supply chain companies?

For most of OLED's commercial history, the industry operated as a near-monolith: virtually every panel maker deposited RGB organic materials through a Fine Metal Mask (FMM) on 6th-generation glass (or polyimide substrates with a glass carrier), while LG Display stood as the sole practitioner of its WRGB architecture for large-area OLED production.

In recent years, we have seen the emergence of new OLED architectures, processes and materials that signal the end of this technological uniformity. In this article, we examine the different technologies, speculate how the industry is changing and where it is headed - and understand the implications for supply chain companies. 

That era of technological uniformity is ending — and ending rapidly. The industry has now fractured into at least six distinct manufacturing paradigms running in parallel: traditional FMM deposition on 6-Gen, next-generation FMM on 8.6-Gen, photolithography-based maskless OLED (ViP, eLEAP, MAX OLED), inkjet-printed RGB OLED, and WOLED (WRGB) and QD-OLED large-area deposition. in addition to these processes, we may be witnessing the first real fragmentation in OLED stack recipes with Visionox's pTSF material platform,
