Abstract
A manufacturing method of an array substrate includes the steps of providing a base plate and forming a thin-film transistor (TFT) layer on the base plate; forming a quantum dot layer on the TFT layer; and forming a protective filter layer on the quantum dot layer to provide protection to the quantum dot layer. The protective filter layer also provides an effect of light filtering in order to prevent ultraviolet light or blue light from transmitting therethrough.
Claims4
An array substrate manufacturing method, comprising the following steps:
- (1) providing a base plate and forming a thin-film transistor (TFT) layer on the base plate;
- (2) forming a quantum dot layer on the TFT layer;
- and
- (3) forming a protective filter layer on the quantum dot layer, wherein the protective filter layer provides an effect of light filtering so as to prevent ultraviolet light or blue light within a predetermined waveband from transmitting therethrough, and
- further comprising the following step:
- (4) forming a color filter layer on the protective layer.
