| titleOfInvention | QLED device, preparation method of QLED device, and display device |
| abstract | The invention discloses a QLED device, a preparation method of the QLED device and a display device, wherein the QLED device comprises an anode, a composite light-emitting layer and a cathode arranged in sequence, and the composite light-emitting layer comprises a first quantum dot layer and a second quantum dot layer and a connecting layer, the connecting layer is located between the first quantum dot layer and the second quantum dot layer, and the materials of the first quantum dot layer and the second quantum dot layer are core-shell quantum dots, The connection layer material is the same as the core-shell quantum dot shell material. Among them, the connecting layer effectively isolates the quantum dots and increases the distance between the first layer of quantum dots and the second layer of quantum dots, reduces the accumulation of quantum dots, improves the luminous efficiency of quantum dots, and prolongs the life of QLED devices. Moreover, keeping the material of the connection layer consistent with the shell material of the core-shell quantum dots facilitates the transport of carriers between the two layers of quantum dots, and avoids the energy extreme difference between different materials. |
