Photolithography as enabler of AMOLED displays beyond 1000 ppi

This paper describes the potential of hi-res display fabrication using OLED photolithography. We demonstrate 1250 ppi multicolor arrays, pixel scaling down to 3 µm pitch, integration in active displays, and improving lifetime after patterning (200 hours T75, smOLEDs). Photolithography can enable low-cost, high resolution displays for the 8K - VR era
