Problems solved by technology

Due to the characteristics of high luminous efficiency and high color gamut, quantum dots have been used in high-end TVs in recent years. However, due to the fear of water and oxygen, quantum dots are severely quenched in temperature, and the cost of materials is high, which makes mass production more difficult.

Abstract

The invention discloses a quantum dot liquid crystal display device. The quantum dot liquid crystal display device comprises a light guide plate, a packaging layer and a liquid crystal panel which are overlapped in turn from bottom to top, wherein the packaging layer comprises optical packaging glue and a dotted material; the optical packaging glue is glued between the light guide plate and the liquid crystal panel; the dotted material is scattered in the optical packaging glue; the dotted material is composed of a green light quantum dot and a fluoride down-conversion photoluminescence material. The invention also discloses a manufacturing method of the quantum dot liquid crystal display device. According to the invention, the green light quantum dot is packaged between the light guide plate and the liquid crystal panel; the low water-permeable oxygen-permeable characteristics of a glass substrate and the light guide plate are utilized, so that the display device has relatively high reliability; the dotted material which is composed of a green light quantum dot and a fluoride down-conversion photoluminescence material is packaged in the optical packaging glue in low refractive index, so that the farther spreading of the blue light in the light guide plate is benefited, meanwhile the color gamut of the liquid crystal display is greatly increased and the purpose of ultrathin liquid crystal display can be achieved.

Description

technical field [0001] The invention relates to the field of quantum dot display technology, in particular to a quantum dot liquid crystal display device and a manufacturing method thereof. Background technique [0002] At present, thinning and high color gamut have become the mainstream development trend of liquid crystal displays. Due to their high luminous efficiency and high color gamut, quantum dots have been used in high-end TVs in recent years. However, due to the fear of water and oxygen, quantum dots are severely quenched in temperature, and the cost of materials is high, making mass production more difficult. Therefore, how to reduce the use of materials and improve product reliability has become a prerequisite for mass production of quantum dot display products. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a quantum dot liquid crystal display device and a manufacturing method thereof, which can ...
