We have successfully developed stable poly-crystalline oxide semiconductor (Poly-OS) as channels of TFT on Gen.6 glass substrates. This technology has significantly improved mobility and stability at the same time, achieving both extremely low off-state current similar to conventional oxide TFTs and high on-state current equivalent to LTPS TFTs.
