We report the active matrix micro-LEDs (AMLEDs) with high brightness over 40,000 cd/m 2 . Active-matrix low temperature poly-Si TFT with mobility over 150 cm 2 /Vs by using blue laser annealing is used for AMLEDs. A 256 pixels micro-LED with ~ 40,000 cd/m 2 at the driving current of 10 mA is fabricated and then 1,024 pixels micro-LED is demonstrated using Au bonding on the LTPS TFT backplane.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
