We review here the LTPS and oxide TFT technologies for micro-LED displays. We have developed BLA of a-Si for LTPS TFTs, exhibiting a high field-effect mobility over 150cm2/Vs for p-channel device. On theother hand, oxide TFTs using bulk-accumulation (BA) mode exhibits an effective field effect mbility over 50 cm²/Vs. The BLA TFT backplane was applied to drive a micro-LED displays using digital driving. Oxide TFT backplane was used for micro-LED with high contrast ratio. The LTPO technology and QD color conversion technology will be explained for micor-LED displays.
