AP Systems achieves 1000 PPI with new FMM technology

At the iMID 2017 conference in Korea, AP Systems announced that it realized high density OLED evaporation using new FMM technologies. By adopting ultra-short pulse laser (USPL), AP Systems achieved a 1,000 PPI. Changing the pin-hole shapes, the company says this technology can even reach 1,170 PPI.

High PPI OLEDs are especially important for VR applications, which require much higher pixel densities as the display is used very close to the eye. In May 2016 Samsung demonstrated a 5.5" 3840x2160 - which reaches 806 PPI, and according to reports Samsung were able to produce a 1,200 PPI AMOLED in March 2017.

Both Sunic Systems and OLEDON developed plane-source evaporation shadow mask process that can achieve 2,250 PPI.
