At Sunic Systems ready OLED display with a density of 1500 pixels per inch; the technology allows to obtain 2250 pixels per inch
The company Sunic System presented the development in the field of AMOLED panels, making it possible to manufacture displays with very high pixel density. The pixels are formed by deposition through a mask (FMM), but using a planar source of evaporable OLED materials, not linear, as is the case in modern production.
This has helped to produce a panel with a density of 1500 pixels per inch, placing a mask with cells of 100 µm at a distance of 1.1 µm. According to the developers, the technology allows to obtain the density of 2250 pixels per inch. It is necessary to reduce the distance to 0.37 µm. For clarity: such a density corresponds to a resolution of the display of the mobile device 11K. High-resolution displays demanded in VR applications.
The use of planar source materials also allows the manufacture of OLED panels of large size, sacrificing density (200 pixels per inch). Prior to the development of Sunic Systems technology FMM imposed more stringent limits on the size of substrate that had to be cut before the deposition of OLED materials.
