Quantum dots (QDs) have received widespread attention because of their adjustable emitted wavelength of light, color purity, and high quantum efficiency, which have great potential in applications requiring high-color-quality displays with photoluminescence. In this paper, the progress of QD backlights based on QDs On-chip, QDs On-surface, and QDs On-edge are reviewed, including their principle, structures, and current applications. Then, several other novel QD backlight structures are also introduced, prompting a proposal for two novel QD backlight technologies. One is the QDs volume-scattering diffusion plate, which is prepared by injection molding with a mixture of QDs and polymer at a low temperature. The other is a QDs microstructure light guide plate, which is fabricated by transferring QDs on the surface of a light guide plate through screen printing or inkjet printing. Both of these two QDs plates can achieve high color gamut while being simple to process, being low in cost, and holding high production efficiency. These have wide applications in high-color-gamut liquid crystal displays.
