Quantum dot backlight module, displayer and quantum dot lens manufacturing method

Abstract

The invention provides a quantum dot backlight module. The quantum dot backlight module comprises a lamp bar which comprises a substrate, a blue light LED arranged on the substrate and electrically connected with the substrate, and a quantum dot lens arranged on the substrate and arranged on the periphery of the blue light LED in a covering mode to combine blue light rays emitted by the blue light LED into white light rays. The quantum dot lens comprises a lens body and a quantum dot which are integrated and formed integrally. The invention further provides a quantum dot lens manufacturing method. The quantum dot lens manufacturing method comprises the following steps that S1, the quantum dot is added into a polymethyl methacrylate material, and the quantum dot and the polymethyl methacrylate material are melted and mixed into a quantum dot lens raw material; and S2, the quantum dot lens raw material is injected into a mold to prepare the quantum dot lens. According to the quantum dot backlight module provided by the invention, as the quantum dot lens is prepared by mixing and integral formation of the quantum dot and polymethyl methacrylate, the quantum dot lens is simple in producing process and low in cost.

Description

technical field [0001] The invention belongs to the technical field of backlighting, and more specifically relates to a method for manufacturing a quantum dot backlight module, a display and a quantum dot lens. Background technique [0002] With the continuous development and progress of display technology, human beings have higher and higher requirements for displays, as well as requirements for display clarity and vivid colors. The use of quantum dot technology in the display can make the color gamut reach more than 100%, and the colors are richer, brighter and more realistic. At present, the quantum dot displays on the market all use the side-entry quantum dot backlight module, which includes a light bar. The light bar includes a substrate, a blue LED and a lens. The blue LED emits blue light. The lens has a cavity inside. Filled with quantum dots, so that the color gamut of light can achieve 100% effect through quantum dots. However, this solution needs to form a cavit...
