We developed the novel TFT backplane structure on glass for ultra-high resolution (1443 ppi) AMOLED VR display. The Mixed TFT backplane based on the combination of bottom-gate poly-Si TFTs (BGPs) and top-gate poly-Si TFTs (TGPs) has solved many issues such as integrating AMOLED pixel circuit in very small area and retaining TFT characteristics on glass for AMOLED VR display.
