Abstract
A method of patterning a quantum dot light emitting device and a quantum dot light emitting device are provided. A quantum dot material is printed by providing a printing mesh having a predetermined pattern, which avoids issues such as slow speed and complex process brought by printing, transfer, and the like processes in a conventional method of patterning a quantum dot light emitting device in the prior art. This can reduce printing process and save printing time.
