Abstract

A quantum dot diaphragm comprises a first barrier layer, a first quantum dot layer, a substrate layer, a second quantum dot layer and a second barrier layer. The first quantum dot layer comprises green-light quantum dots uniformly dispersed in a polymer material, the second quantum dot layer comprises red-light quantum dots uniformly dispersed in the polymer material, the first barrier layer is deposited on the first quantum dot layer, and the second barrier layer is deposited on the second quantum dot layer. The quantum dot diaphragm is excellent in performance and suitable for industrialization.

Description

technical field [0001] The invention relates to the field of display, in particular to a quantum dot film used in the field of backlight display. Background technique [0002] Quantum dots are an effective way to improve the color gamut of LCD backlight display products. Compared with ordinary white LEDs, the use of quantum dot film with blue LEDs can increase the color gamut of LCD from the original 70% NTSC to more than 100% NTSC, thus showing better color saturation. [0003] 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 the two barrier films and the polymer glue mixed with red and green light quantum dots Covered into a film and cured. The barrier film consists of depositing an inorganic coating on an organic substrate. Contents of the invention [0004] The purpose of the present invention is to provide a novel quantum dot mem...
