A colloidal quantum dot (QD) is a semiconductor nanoparticle whose electrical and optical properties change as its size decreases to a nanometer scale due to quantum confinement effect. Unlike conventional light-emitting materials, the size and shape of the QD can be tuned to emit light very efficiently at red, green, and blue wavelengths with high color purity, thus enabling us to fabricate high-picture quality displays. In the liquid crystal display (LCD), red and green QDs are used for enhancing color gamut. QDs in the light-emitting diode structure (QLED) can also be directly excited by the electrical excitation, generating efficient three primary colors. The performance of QLEDs has been greatly improved as a result of remarkable advances in the QD synthesis, device engineering and fundamental understanding of the device physics. Here, we will review recent progress of the QD technology for display applications with an emphasis on QLEDs.
