Bulk Accumulation Oxide TFTs for Flexible AMOLED Display with High Yield Integrated Gate Driver

摘要

A 4-inch flexible active-matrix organic light-emitting diode (AMOLED) display with a Bulk-Accumulation (BA) oxide thin-film transistors (TFT)-backplane and BA oxide TFT-based high yield integrated gate-driver is demonstrated. The gate-driver with 320 stages exhibit excellent driving ability with rising and falling times less than 1 μs - even under tensile strain induced by bending to a radius of 3 mm- which makes it suitable for flexible mobile AMOLED display applications.
