Complete with substrate, an active matrix for a flexible display need only be 4μm thick, according to the Korea Advanced Institute of Science and Technology (KAIST). The matrix of ultra-thin n-type transparent oxide thin-film transistors (TFTs) for the backplane were initially fabricated on a sacrificial laser-reactive substrate. Laser irradiation from the backside of the substrate …
