“…Organic light-emitting diodes (OLEDs) have received significant attention as the most demanded forthcoming display and lighting technology because of their low cost, lightweight, low power consumption, high brightness, and high contrast ( Chen et al, 2018 ; Lee et al, 2019a ; Lee et al, 2019b ; Abroshan et al, 2020a ; Abroshan et al, 2020b ; Abroshan et al, 2020c ; Abroshan et al, 2020d ). Recent developments in OLEDs with flexible panels have opened a new avenue for innovative technologies to fabricate cost-effective large-area, wearables, foldable and shape-fitting displays ( Jeong et al, 2020 ; Song et al, 2020 ; Yoo et al, 2020 ).…”
