Abstract
A method for making inkjet-printed encapsulated quantum dots and a light conversion unit using the inkjet-printed encapsulated quantum dots are disclosed. The light conversion unit comprises: a substrate, a light convertor carrying layer having several accommodating grooves, several first micro encapsulated QD structures, and several second micro encapsulated QD structures. In case of letting the substrate has a hydrophobic surface, at least one inkjet-printing nozzle is utilized for injecting a first QDs solution and a second QDs solution into the accommodating grooves by a form of droplet, such that one third of the accommodating grooves are formed with the first micro encapsulated QD structure, and another one third of the accommodating grooves formed with the second micro encapsulated QD structure. Moreover, a micro LED display panel having the light conversion unit exhibits a color gamut that is approximately 110% NTSC.
