The Development of IJP-QLED Display towards its Commercialization

Quantum dots light emitting diodes(QLEDs), have been widely recognized as the most promising next-generation display technology candidate. At current stage, the lifetime issue of QLEDs remains the critical challange towards commercialization, especially for blue devices. For mass-production of QLEDs, other issues need to be addressed including device structure compatible for production and improvement in the Ink-Jet-Printed(IJP) device performances.
To solve these issues, TCL QLED team has made significant progress in the development of high-performance QLED devices.The lifetime performance of QLED devices were able to be competitive with that of OLEDs. We have successfully adopted the top emission device structure, which is compatible for panel mass-production with better current efficiency. Furthermore, the performance gap between spin-coated and IJP devices has been largely resolved, owing to the effort on the optimization of inks, film quality and IJP fabrication flow. Such progress is expected to shed light on the dawn of QLED commercialization.
