Quantum dot light emitting diodes (QLEDs) that electrically excite quantum dots (QDs) are the future of QD displays, owning to the excellent optical properties of QDs, such as narrow emission spectra, size-controlled emission wavelength, high quantum yield and inherent stability. During the past twenty years, the efficiency of QLEDs has dramatically increased from less than 0.1% to more than 20%, but the operation lifetime of these devices and other key factors were still far below the requirement of display applications. In this report, we will discuss our concerns and progress in IJP QLEDs Display, and talk about what we should do to commercialized this technique in the future.
