Abstract

The invention discloses a quantum dot diaphragm and a preparation method of the quantum dot diaphragm and a backlight module, wherein the quantum dot diaphragm comprises a first blocking layer, a first quantum dot layer, a base layer, a second quantum dot layer and a second blocking layer which are arranged in sequence; the first quantum dot layer comprises first quantum dots which are uniformly dispersed in a polymer material; the second quantum dot layer comprises second quantum dots which are uniformly dispersed in the polymer material; the first blocking layer bears the first quantum dot layer; and the second blocking layer bears the second quantum dot layer. By virtue of the quantum dot diaphragm, the structure design of the quantum dot diaphragm in the prior art is changed, and a self-absorption phenomenon caused by mixing of different quantum dots is avoided. The backlight module comprises the quantum dot diaphragm.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of the Chinese patent application "201710604041.5" entitled "Quantum dot film and its preparation method, backlight module" filed on July 21, 2017, the entire content of which is incorporated herein by reference. technical field [0003] The present application relates to the field of quantum dots, in particular to a quantum dot film, a preparation method thereof, and a backlight module. Background technique [0004] Compared with ordinary white LEDs, the use of quantum dot film and excitation light source can increase the color gamut of LCD from the original 70% NTSC to more than 100% NTSC, thus showing better color saturation. [0005] The existing quantum dot membrane is composed of two barrier films sandwiched by a quantum dot layer, which is in a sandwich structure. The manufacturing process mainly includes: coating two barrier films and polymer glue including quantum dots to ...
