  • Patent number: 11201305
    Abstract: A display panel comprises a substrate, active switches and light-emitting diodes formed on the substrate. The active switches are disposed between the substrate and the light-emitting diodes. Each light-emitting diode comprises a first electrode, a second electrode, and a quantum dot luminescent layer. The quantum dot luminescent layer comprises a mesoporous frame. The mesoporous frame adopts a self-assembling form, the mesoporous frame serves as a main material, and quantum dots are disposed in the mesoporous frame. The first electrode, the quantum dot luminescent layer and the second electrode are stacked in order. Since the quantum dots are disposed in the mesoporous frame, the sizes of the quantum dots and the uniformity of their arrangement are adjusted and controlled, the light-emitting diodes with different luminous colors depending on the sizes of the quantum dots are then adjusted.
