Abstract
The present application provides a method of fabricating a quantum dot color film substrate, red and green quantum dots are respectively formulating into red and green quantum dot inks, then formation is performed by an inkjet printing, and a color filter layer is obtained, thereby brightness and color saturation of displays can be increased; simultaneously, the red quantum dot ink and the green quantum dot ink at least have an ink of epoxy resin system therein, when the ink of epoxy resin system is yet cured, a graphene conductive layer is formed thereon to act as an electrode, so that a greatly improved adhesion of the graphene conductive layer and the color filter layer can be obtained. Additionally, to replace ITO by utilizing graphene as a conductive layer can alleviate current issues of few ITO sources and increasing price, and the graphene has conductivity and high transmittance that make display quality of TFT-LCD screen be guaranteed, and an overall thinned and lightened panel be achieved. Such design helps increasing conductivity and integrating benefits, and also has very great application prospect in curved panel market.
