LIGHT EMITTING DEVICE AND MANUFACTURING METHOD THEREOF

Номер: WO2020015432A1
Автор: WANG, Hailin, LAN, Yunjian, DU, Xiangpeng
Принадлежит:

The invention provides a light emitting device and a manufacturing method thereof. The light emitting device comprises a substrate, an LED chip, a quantum dot composite material layer and a first protective layer; the LED chip is disposed on the surface of one side of the substrate; the quantum dot composite material layer is arranged on the surface of one side away from the substrate of the LED chip; the first protective layer is arranged on the surface of one side away from the LED chip of the quantum dot composite material layer; wherein the quantum dot composite material layer comprises a water-soluble polymer matrix and quantum dots dispersed in the water-soluble polymer matrix; the material of the first protective layer is a first inorganic oxide or a first water-blocking polymer; and the material of the water-soluble polymer matrix is an antioxidant polymer. The combination and the structural design of the described materials enable the quantum dot composite material layer better ...

QUANTUM DOT COMPOSITION, QUANTUM DOT LUMINESCENT MATERIAL, PREPARATION METHOD THEREFOR AND LIGHT-EMITTING DEVICE COMPRISING SAME

Номер: WO2019042068A1
Автор: FANG, Long, LV, Mengbing, WANG, Hailin, ZHAO, Fei

Provided in the invention are a quantum dot composition, a quantum dot luminescent material, a preparation method therefor and a light-emitting device comprising the same. The quantum dot composition comprises a microemulsion and a polymer precursor for dispersing the microemulsion, wherein the microemulsion comprises a quantum dot, a dissolution medium for dissolving the quantum dot, and an emulsifier encapsulating the dissolution medium. First dissolving the quantum dot in the dissolution medium, and then adding the dissolution medium in which the quantum dot is dissolved to the polymer precursor. Due to the fact that the emulsifier is amphiphilic, with one end connected to the polymer precursor, and the other end connected to the dissolution medium, and by means of the emulsification of the emulsifier, the dissolution medium in which the quantum dots are dissolved can form a microemulsion, effectively avoiding the contact between the quantum dot and the polymer precursor, thereby ensuring ...

ORGANIC BARRIER FILM, PREPARATION METHOD OF ORGANIC BARRIER FILM, AND QUANTUM DOT DEVICE

Номер: WO2020088418A1
Автор: WANG, Hailin, HU, Qile, KANG, Yongyin, YE, Jiamin
Принадлежит:

Disclosed are an organic barrier film, a preparation method of the organic barrier film, and a quantum dot device. The organic barrier film comprises a substrate layer, an adhesive layer, and an oxygen barrier layer arranged sequentially from top to bottom. The oxygen barrier layer comprises polyvinyl alcohol, and a chemical cross-linking is formed between the adhesive layer and the oxygen barrier layer. The present invention achieves the following beneficial effect: the formation of a chemical cross-linking between an adhesive layer and an oxygen barrier layer improves the adhesive force of the oxygen barrier layer on the surface of the substrate layer.

MANUFACTURING PROCESS OF LIGHT-EMITTING PART AND LIGHT-EMITTING PART

Номер: WO2020063485A1
Автор: KANG, Yongyin, DU, Xiangpeng, WANG, Hailin, ZHOU, Jianhai, LAN, Yunjian
Принадлежит:

A manufacturing process of a light-emitting part and a light-emitting part. The manufacturing process of a light-emitting part comprises: step S1, manufacturing a quantum dot film (40); step S2, providing an LED unit, wherein the LED unit comprises at least one LED chip (20); step S3, disposing a first transparent adhesive layer (30) on the exposed surface of each LED chip (20); step S4, disposing the quantum dot film (40) on a surface of the first transparent adhesive layer (30) away from the LED chip (20). In the manufacturing process of the light-emitting part, a quantum dot film (40) is first manufactured, and instead of being cured by injecting a quantum dot glue, the quantum dot material distribution in the light-emitting part obtained by this process is more uniform, such that the light-emitting part emits more uniform light.
