Problems solved by technology

[0003] However, the quantum dot colloid material in the quantum dot tube is very special, and it is easy to react with oxygen and water in the air, so it must be placed in an airtight space that is anaerobic and water-resistant, which creates a difficulty. Dot materials are filled into airtight glass tubes, and there should be no moisture and air in the glass tubes, which is a technical problem to be solved at present

Abstract

Provided are a quantum dot light bar production method and production system. The method comprises the following steps of: providing a quantum dot colloid material and a glass tube (40), the glass tube (40) comprising an open end and a closed end; placing the open end of the glass tube (40) downwardly to put the quantum dot colloid material into the glass tube (40) from the open end (S10); filling the glass tube (40) with protective gas to form a gas plug (S20); making the glass tube (40) be subjected to a heat treatment in the atmosphere of the protective gas (S30); heating the open end of the glass tube (40) until it is melted and sintered (S40); and making the glass tube (40) be subjected to an annealing treatment in the atmosphere of the protective gas (S50).

Description

technical field [0001] The invention relates to the technical field of quantum dot light strips, in particular to a production method of quantum dot light strips. Background technique [0002] Quantum dots are a series of nanoparticles that are fluorescent, typically in the range of 1-20 nanometers, and have a crystalline structure. Quantum dots have size-tunable optical properties, high quantum efficiency, relatively narrow half-width, and resistance to photodegradation. As a new generation of luminescent materials, quantum dots are being used in LED displays. The photoelectric characteristics of the quantum dot tube are very unique. When it is stimulated by electricity or light, it will emit very pure high-quality monochromatic light of various colors according to the diameter of the quantum dot. The main principle of applying quantum dots to display technology is to excite quantum dot crystals of different sizes in quantum dot tubes through pure blue light sources, ther...
