Abstract

The invention provides a UV curing adhesive, a quantum dot light conversion film and a white light emitting device comprising the quantum dot light conversion film. The UV curing adhesive comprises a low-polarity acrylate oligomer, an active dilute monomer and a photoinitiator, wherein the low-polarity acrylate oligomer is an oligomer with a structure of formula (I) or (II); R1 and R2 in the structure of formula (I) are separately selected from silicon atom and carbon atom; R3 is SiH3, CH3 or phenyl; p is 5-10; and in the formula (II), R4 is phenyl, naphthyl or C2-C10 alkyl, and n is 5-10. The UV curing adhesive has the characteristics of low polarity, water resistance, oxygen resistance and no acid or alkali and facilitates stable dispersion of quantum dots in the UV curing adhesive, and thus a quantum dot light conversion film with relatively high light color stability and brightness stability is obtained.

Description

technical field [0001] The invention relates to the field of light emitting devices, in particular to a UV curing adhesive, a quantum dot light conversion film and a white light light emitting device comprising the quantum dot light conversion film. Background technique [0002] The color gamut is usually called a color space, which represents the specific situation of a color image that can express the color of the color space. In terms of computer monitor applications, people mostly use sRGB as the standard color gamut definition, while in audio and video, they mostly use NTSC definition, and NTSC is a set of standard TV developed by the National Television Standards Committee (National Television Standards Committee) A broadcast transmission and reception protocol that covers a wider range of colors than the sRGB standard. However, the presentation of the color gamut value mainly depends on the choice of backlight. As we all know, liquid crystal panels are completely im...
