BOE Technology Group Co. Ltd. developed 55-inch 8K active matrix quantum dot light-emitting diode (AMQLED) display, which is currently exhibited in the SID display week 2022 in San Jose, CA. This is another innovation breakthrough in active matrix quantum dot display following the release of 55-inch 4K AMQLED display demo in 2020.

55-inch 8K AMQLED display utilizes electroluminescent quantum dot technology, combining with the oxide TFT driving and inkjet printing process for all functional layers (except cathode), which made it the real active self-emitting quantum dot display. Comparing to quantum dot backlight technology, AMQLED is free of backlight, while the quantum dots are laminated by injected current. AMQLED technology has the advantages of self- emitting, wide color gamut, and long lifetime, which make it the direction of quantum dot display technology.

Meanwhile, inkjet printing is considered to be the most mutual manufacturing process for QLED mass production, which can greatly improve the utilization rate of materials, thereby effectively reducing manufacturing costs.
