Quantum dot fluorescent film with double-monocolor-layer structure and manufacturing method thereof

Abstract

The embodiment of the invention provides a quantum dot fluorescent film with a double-monocolor-layer structure and a manufacturing method thereof; the quantum dot fluorescent film with the double-monocolor-layer structure includes two layers of substrates laminated together; the substrates are PET films, and the opposite inner surfaces of the two-side substrates are respectively provided with a green quantum dot inner film layer made of a green quantum dot composite colloid and a red quantum dot inner film layer made of a red quantum dot composite colloid. According to the embodiment of the invention, the PET films as the substrates are respectively coated with red and green monocolor quantum dot composite colloids, and then two monocolor quantum dot films are laminated to obtain the quantum dot fluorescent film with the double-monocolor-layer structure. With the same amount of quantum dots, the quantum dot fluorescent film with the double-monocolor-layer structure provided by the embodiment of the invention has higher optical intensity, thereby obviously reducing the amount of the quantum dots needed to realize same optical indexes.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a quantum dot fluorescent film with a double monochromatic layer structure and a manufacturing method. Background technique [0002] Liquid crystal display technology is the current mainstream display technology, occupying more than 90% of the market. Traditional liquid crystal displays have shortcomings such as insufficient color expression and low color purity, which is reflected in the data with a low display color gamut. [0003] In the prior art, the quantum dot display technology is used to improve the color gamut index of the liquid crystal display, which can make it have a fuller color expression, which is an upgrade to the existing liquid crystal technology. The blue LED light source is used to excite the red and green quantum dot fluorescent materials, and the three colors of blue, red and green are mixed to obtain white light. Quantum dots have a narrower spectral ...
