Abstract

The invention discloses a quantum dot film, a backlight module and a display device. The quantum dot film comprises a green luminescent layer and a red luminescent layer which are positioned on the same layer, wherein the green luminescent layer is made from a green quantum dot photoluminescence material; and the red luminescent layer is made from a red nonquantum dot photoluminescence material. According to the quantum dot film, the backlight module and the display device provided by the embodiment of the invention, the secondary absorption in the quantum dot film is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot film, a backlight module and a display. Background technique [0002] At present, the traditional backlight modules on the market generally rely on the loss of brightness viewing angle to achieve the purpose of increasing the brightness of the front viewing angle. One-third of the brightness viewing angle of the backlight module is basically below 100°, which leads to poor display effect when viewed from the side. Difference. [0003] In order to expand the viewing angle of the backlight module, the quantum dot film can be introduced into the structure of the traditional backlight module. Quantum dots are materials with a crystalline structure, usually in the size range of 1-20 nanometers, which can emit fluorescence isotropically when excited by an appropriate light source or voltage. [0004] The inventors of the present invention have found in the long-term re...
