Problems solved by technology

However, since water vapor and oxygen will enter the QD-film from the outside, and the quantum dots in the QD-film are very sensitive to water vapor, oxygen, and trace amounts of acid and alkali, the quantum dots are easily damaged by trace amounts of water. Gas, oxygen, and the presence of acids and bases, which lead to the failure of the overall QD-film

Abstract

The invention provides an adhesive and a light-emitting film layer structure. The adhesive comprises an oligomer, wherein the oligomer is formed by polymerizing a compound I and a compound II; the compound I has a structural formula A shown in the specification; the compound II has a structural formula B shown in the specification; in the structural formula A, R1 and R2 are respectively a carbon atom or a silicon atom, and R3 is silicyl, alkyl or phenyl; in the structural formula B, R4 is phenyl, naphthyl or alkyl, and n is an integer more than or equal to 1. The adhesive has the beneficial effects that as the oligomer introduces the structural formula A and the structural formula B, the adhesive with the oligomer has low polarity and can be cured by UV and then a quantum dot light conversion layer can be formed by the UV cured adhesive; as the adhesive to which the structural formula A and the structural formula B are introduced has high density, quantum dots in the quantum dot light conversion layer can not become invalid due to existence of outside moisture and oxygen.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an adhesive and a light-emitting film layer structure. Background technique [0002] In the field of display and lighting, the color gamut is usually called the color space, which represents the specific color conditions that a color image can express. The presentation of the color gamut value of the display device mainly depends on the selection of the backlight module. Existing backlight modules are limited by their internal structures and related devices, resulting in reduced luminous efficiency of the backlight modules. In order to achieve a high color gamut value of the display device, it is usually necessary to increase the energy consumption of the backlight module to ensure that the display device has an appropriate brightness. [0003] Currently commonly used backlight modules are quantum dot light conversion films (QD-film) and related devices. Its light-emitt...
