Abstract
Disclosed in the invention is a method of producing a layered quantum dot LED backlight. Fluorescent glue A is produced and disposed on the surface of an LED lens; then fluorescent glue B is produced and disposed on the surface of the fluorescent glue A; and at last one layer of photocurable glue as a protective film is disposed on the fluorescent glue B, thus the layered LED lens is produced. The LED lens is fixed on an LED light strip. The light emitted by the LED light strip is mixed with the light emitted by the fluorescent glue A and fluorescent glue B so that white light is obtained. Compared with traditional backlight materials, a quantum dot material has a narrower half-wave width such that the color gamut value of the LED backlight is increased greatly. According to the producing method in the invention, the color gamut value of the LED backlight can reach 95% or more of NTSC standard. Moreover, the method is low-cost and simple. In the prior art, various kinds of fluorescent materials are mixed directly and react with each other, so that the structure of the quantum dot fluorescent material is destroyed and the light is attenuated. The layered fluorescent glue solves the above problems.
