Abstract
The disclosure discloses a sealant and a method for fabricating the same, and a display device. The sealant includes a thermal-curing agent and an epoxy resin, wherein the thermal-curing agent includes a diphenyl ketone alcohol compound capable of emitting a fluorescent light and a phosphorescent light simultaneously.
Claims20
A sealant film, formed from a sealant comprising a thermal-curing agent and an epoxy resin, wherein the thermal-curing agent comprises a diphenyl ketone alcohol compound capable of emitting a fluorescent light and a phosphorescent light simultaneously;
- wherein the sealant film is a copolymer fluorescent/phosphorescent double-emission sealant film in which a light-emitting molecule of the diphenyl ketone alcohol compound is embedded into an epoxy resin molecule chain with a chemical bond;
- wherein:
- when the sealant film has no breakage, and ultraviolet (UV) illumination stops after lasting for a preset time, the sealant film emits a green phosphorescent afterglow;
- when the sealant film is partially broken, under the UV illumination, the sealant film emits the fluorescent light and the phosphorescent light simultaneously, which appear as a blue and white mixed fluorescent/phosphorescent light;
- and
- when the sealant film is completely broken, under the UV illumination, the sealant film emits a blue fluorescent light.
