Abstract

We study the thermal distribution of a flexible/transparent unpackaged 32×32 micro-LED array on PET substrate up to a brightness rating of 5,000 nits at room temperature. The temperature variation of single pixel is 3-4 °C. The average temperatures of the array range from 30°C to 41 °C, showing stable performance.
