Abstract

Abstract : 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.
