| titleOfInvention | A kind of quantum dot light-emitting diode and preparation method thereof |
| abstract | The invention discloses a quantum dot light emitting diode and a preparation method thereof, wherein the quantum dot light emitting diode comprises an anode, a quantum dot light emitting layer and a cathode, and the quantum dot light emitting layer comprises at least one first quantum dot light emitting layer and at least one quantum dot light emitting layer. A second quantum dot light-emitting layer, the first quantum dot light-emitting layer and the second quantum dot light-emitting layer are alternately arranged, the first quantum dot light-emitting layer includes the first quantum dots, and the second quantum dots emit light The layer includes second quantum dots, and the shape of the first quantum dots is different from that of the second quantum dots; or, the quantum dot light-emitting layer includes first quantum dots and second quantum dots, and the first quantum dots different from the morphology of the second quantum dots. The invention combines a variety of quantum dots with different shapes to reasonably match the quantum dot light-emitting layers, and specifically arranges quantum dot layers with different shapes at intervals, thereby improving the stability and charge transfer efficiency of the quantum dot light-emitting layers. |
