Micro-LED display consist of arrays of Micro-LEDs and driving backplane with bonding technologies. As the size of LED get smaller, the amount of LED chips becomes a huge number. The thermal issue of Mini/Micro-LEDs needs to be considered. We report a 32×32 flexible Mini-LEDs array with driving current of 10mA under applied bias of 2.6V. The result of testing temperature distribution in different brightness shows that the Mini-LED array satisfy the requirement of thermal stability.
