Abstract

Two types of flexible organic light-emitting diode (OLED) displays are described. One is a passive matrix (PM) display with 128 (RGB) x 72 pixels, and the other is an active-matrix (AM) panel with 4 x 4 green pixels using organic thin-film transistors (OTFTs). The emitting layer of these displays is based on high-efficiency phosphorescent materials. The PMOLED display showed a clear color video image even when it was bent. The AMOLED panel could actively drive the OLED pixels. These results suggest that the OTFT-driven OLED display would be a promising candidate for rollable mobile displays.
