According to reports from Korea, Samsung Display is interested in acquiring OLED IP and patents from Semiconductor Energy Laboratory (SEL). These patents detail an OLED production process that does not require the use of fine metal mask (FMM) evaporation.
The use of FMM to deposit and pattern OLED displays is seen as a major setback towards higher density OLED displays, and it also limits the aperture ratio. It is no wonder that Samsung is interested in such technology, as other display makers have developed similar technologies that offer massive performance boost over the standard FMM process.
In 2022, Japan Display (JDI) announced that it has developed a "historic breakthrough in display technology" - a new OLED deposition process which they refer to as eLEAP, that is said to be cost effective and can be used to create freeform OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM).
