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

The invention discloses a production method of a quantum dot light bar. The method comprises the following steps that a quantum dot adhesive and a glass tube are provided, the opening end of the glass tube faces downwards, the quantum dot adhesive is loaded into the glass tube via the opening end, then the glass tube is filled with protective gas, and a gas embolism is formed in the glass tube; the glass tube containing the quantum dot adhesive is placed in a vacuum tank, the vacuum tank is placed in an infrared heating furnace, vacuumized and then filled with protective gas, and the infrared heating furnace is heated; the glass tube is taken out of the vacuum tank, the opening end of the glass tube is placed on a first heating source to be heated, and the opening end of the glass tube is heated, melted and sintered; and the glass tube is arranged in an annealing cavity with a second heating source, the annealing cavity is vacuumized and then filled with protective gas, and the quantum dot light bar can be obtained by heating the second heating source. By means of the production method of the quantum dot light bar, quantum dots can be poured into the glass tube in a packed mode, no air enters the glass tube, and oxidation is avoided.

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...
