Device for injecting quantum dot colloid for quantum dot pipe encapsulation

Abstract

The invention discloses a device for injecting a quantum dot colloid for quantum dot pipe encapsulation. The device comprises a vacuum machine, a stirrer, and a closed container, wherein the vacuum machine is connected with the closed container by a first pipeline with a vacuum valve; the closed container is connected with a second pipeline with a nitrogen valve, and a third pipeline with a colloid valve; the stirrer is arranged at the bottom of the vacuum machine; the closed container is provided with a glass pipe. According to the device, a quantum dot material can be injected into the glass pipe, the physical structure of the quantum dot colloid material can not be damaged, the encapsulation process is performed in a no-oxygen and no-water environment, the batching aim of a colloid injecting technology in the quantum dot pipe encapsulation can be realized, and the relatively high productivity can be realized.

Description

technical field [0001] The invention relates to a device for filling quantum dot colloid used for encapsulation of quantum dot tubes, and relates to the field of automatic encapsulation technology of quantum dot tubes. Background technique [0002] 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, thereby releasing pure red photons and pure green photons, and projecting them with the remaining pure blue light to the imaging system In this way, quantum dots can be used to emit concentrated energy spectrum, very pure high-quality red / green monochromatic light, which completely surpasses the phosphor emission characteri...

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. The material is potted into a closed glass tube, and there must be no moisture and air in the glass tube, which is a technical problem to be solved at present
