Such high resolutions would make adjacent pixels indiscernible, boosting Virtual Reality’s realism even close up to the eyes. One drawback of existing OLED deposition systems, explained the company, is the use of linear sources that emit the OLED material through a fine shadow mask, creating a shadow angle that limits the resolution at which adjacent pixels can be patterned.

Process developers at Sunic System see plane sources as the solution. Instead of using multiple linear sources, the company would create a plane source by first depositing OLED emitting materials on a metal plate, then reversing it and heating it to use the full plate as the source.

As the materials vertically evaporates and pass through the shadow mask, it would virtually eliminate the shadow distance between pixels (reducing it up to approximately 8 times compared to existing technology), allowing for the production of much higher resolution AMOLED panels.

The company also expects this new process to allow the production of large area RGB OLED TV panels at better yields compared to today’s inkjet printer-based alternatives that rely on soluble OLED emitting materials.

It is anticipated that Sunic System would be a key contributor to Samsung Display’s project EnDK to develop the world’s first 11K mobile display (backed by the Korean government with a USD 26.5 million grant).
