Abstract: A high-color-gamut quantum dot lens and a method for manufacturing a backlight module are provided. The method includes: mixing quantum dots with an acrylic resin, carrying out mixing granulation on the quantum dots and the acrylic resin by using an internal mixer to obtain quantum dot acrylic particles, carrying out injection molding on an acrylic material containing quantum dots to obtain a quantum dot lens, and then spraying a water and oxygen resistant transparent material on the surface of the injection-molded quantum dot lens for encapsulation. Light emitted from a white LED chip irradiates onto the quantum dot lens, and an RGB independent spectrum is superposed on a common fluorescent powder spectrum by means of a quantum dot light conversion material; and the superposed spectrum obtained thereby passes through an LCD screen, and a color display screen with a high color saturation and a wide color gamut will be obtained.

Abstract: A quantum dot lens, a backlight module, a display device and a manufacturing method of the quantum dot lens are provided. The quantum dot lens includes: a first lens, which is a convex lens and is provided with a first lens surface; a second lens, which is a concave lens and is provided with a second lens surface opposite to the first lens surface; and a quantum dot fluorescent resin layer, provided between the first lens surface and the second lens surface, and including more than one quantum dot fluorescent material. With the above structure, the quantum dot lens has a simple manufacturing process and ease of mass production, saves the quantum dot fluorescent material, and solves the problems of poor consistency and blue light leakage of existing quantum dot lenses.
