| titleOfInvention | A quantum dot light-emitting diode |
| abstract | The invention discloses a quantum dot light-emitting diode, which comprises a hole function layer arranged between the anode and the quantum dot light-emitting layer, the hole function layer includes a hole transport layer and a hole buffer layer, and the The hole transport layer is disposed close to the anode, the hole buffer layer is disposed close to the quantum dot light-emitting layer, and the hole buffer layer includes a layer of first holes attached to the hole transport layer. A buffer sublayer, the material of the first hole buffer sublayer is a first hole buffer material or a mixed material composed of a first hole buffer material and a fourth hole transport material, wherein the first hole buffer material is The hole mobility of the buffer material is less than 1×10 ‑6 cm 2 V ‑1 s ‑1 . The hole buffer layer can widen the hole accumulation region and reduce the space electric field near the exciton recombination region, thereby reducing the quantum dot exciton separation and fluorescence quenching, which can not only improve the electric resistance of the hole transport layer, It can also improve the luminous efficiency, stability and lifespan of the QLED. |
