Quantum dot light-emitting device patterning method and quantum dot light-emitting device

Abstract

The embodiment of the invention discloses a quantum dot light-emitting device patterning method and a quantum dot light-emitting device. According to the embodiment of the invention, the method comprises the steps of providing a printing screen with a preset pattern; aligning the printing screen with a first mark preset on a first substrate; printing a quantum dot material on the printing screen to form a first quantum dot layer with the preset pattern on the first substrate; and curing the first quantum dot layer to obtain a second substrate. By printing the quantum dot material through the printing screen, the problems of low speed, complex process and the like caused by using printing, transfer printing and other processes in a common quantum dot light-emitting device patterning methodin the prior art are avoided, the printing process is reduced, and the printing time is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot light-emitting device patterning method and a quantum dot light-emitting device. Background technique [0002] Quantum dot light-emitting devices have received extensive attention because of their advantages such as wide color gamut, low-cost solution preparation, adjustable emission spectrum, and good stability under light. OLED) light-emitting devices have comparable display performance and have the advantage of lower manufacturing costs. Therefore, quantum dot light-emitting devices are likely to replace OLED light-emitting devices and become the next generation of core display devices. [0003] In the manufacturing process of quantum dot light-emitting devices, patterning of quantum dot light-emitting devices is one of the key processes. At present, the patterning of quantum dot light-emitting devices is generally realized by printing or transfer printing proc...
