Abstract
In this study, we investigate the influence of channel length of bendable a-Si:H thin film transistors (TFTs) on their electrical characteristics as a function of bending strain. Under a tensile strain of 1.69%, $8{\mu}m$-channel-length TFT has the threshold voltage shift up to 5.25 V, while $100{\mu}m$-channel-length TFT operates stably.
