Samsung purchases Orthogonal's mask-less OLED production IP

Reports from Korea suggested that Samsung Display acquired 5 patents from US-based Orthogonal, that contains the company's mask-less OLED production process. With this purchase, SDC has a path towards developing its own maskless OLED production.

Maskless OLED production is of high interest lately, as these technology could offer higher pixel aperture ratio leading to higher efficiency, brightness and lifetime and brighter OLEDs, compared to FMM-based production processes. JDI for example claims its eLEAP technology enables an 2X increase in brightness and a 3X increase in lifetime, coupled with reduced production costs.

In January 2023 Samsung filed a motion with the US ITC to halt the import of aftermarket AMOLED displays produced by BOE. A group of OLED makers in China, which includes BOE, answered with a motion of their own, to dismiss an SDC AMOLED patent. This legal battle continues, and the tension between Samsung and BOE is on the rise.

A senior researcher formerly working at Samsung Display, accused of stealing OLED trade secrets with an aim to sell them to Chinese display makers, returns to Korea to face chargers

In 2021, we reported that two researchers working at Samsung Display were convicted of handing over OLED technology to other companies, and are being sent to prison for two years. Representative and directors of the company that bought the technology was also sent to prison and the company was fined. The technology in question relates to Optical Adhesive Materials used in OLED production processes. The arrest of these employees was reported earlier in 2020.

It is now reported that another employee of Samsung Display, also involved in that case (seems to be he was the main organizer of the outfit) fled Korea following his indictment, but has now returned voluntarily to Korea and has been arrested and is now bring charged with violating unfair competition laws in Korea.

Reports from Korea suggest that Samsung Display is interested in acquiring SEL's mask-less OLED production technology

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.
