Fig. 9: Images of large-area ink jet panel substrates and OLEDs.
From: Large area inkjet-printed OLED fabrication with solution-processed TADF ink
a Handheld large-area panel (LAiP) substrate (120 × 120 mm2) with an active area of 80 × 80 mm2 through square chromium gridlines. b Inkjet patterned large area logos on a 100 × 100 mm2 substrate, consisting of The University of Queensland and IIT Kanpur with two rectangular strips of 10 × 70 and 5 × 70 mm2 before the thermal evaporation of other layers. c The LAiP OLED (120 × 120 mm2) operated at 10.5 V with an inset image at 6 V. d The LAiP (100 × 100 mm2) intricate logo OLED biased at 10 V with brightness of ≈500 cd m−2. Brightness measured at the rectangular strip.
