P‐107: Inkjet Printed Uniform Quantum Dots as Color Conversion for Active Matrix Micro‐LED Display

Abstract

Quantum dots (QDs) display have attracted much attention due to their excellent optical properties and solution process. Especially, QDs can act as effective color conversion for light emitting diodes (LEDs). In this work, we fabricated 4-inch QD-microLED display panel by inkjet printing technology, being cooperated with active matrix inorganic microLEDs. Here blue Micro-LED acted as backlight, patterned red and green QD layer acted as converted materials, which exhibited high quantum efficiency, high luminance, high color purity. We believe that inkjet-printed QD display with blue microLEDs would be promising candidate for the next generation display in the near future.
