27‐2: Novel LTPS‐TFT Backplane Structure on Glass for 1,443ppi 4.3‐in. AMOLED VR Display

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.
