Background
Electroluminescence is a physical phenomenon in which electrons excited by an electric field collide with a luminescence center by applying a voltage between two electrodes to generate the electric field, and transition, change, and recombination of the electrons between energy levels are induced to cause luminescence. The electroluminescent device generally comprises a transparent substrate, a transparent conductive electrode, a light-emitting layer, a dielectric layer, a back electrode and an insulating protective layer, and with the development of the electroluminescent technology, the pattern of the electroluminescent device tends to be complicated and colored. The complex patterns are generally realized in two modes, firstly, the patterns are manufactured on the surface of the transparent base material through processes of spray painting, screen printing, transfer printing, film coating and the like, the patterns do not emit light, the patterns are displayed mainly through the light emission of an electroluminescent device serving as a background, the patterns lack gorgeous feeling, the contrast is not high, and the patterns emit light through manufacturing a back electrode pattern in the other mode, so that the contrast is enhanced.
The existing electroluminescent pattern is mainly realized by making a back electrode pattern.

The etching process is complicated and the cost is high.
The UV spray painting is a method for manufacturing patterns commonly used in the printing industry, can clearly manufacture fine patterns, and has the advantages of simplicity, quickness and environmental protection. The UV spray painting is used for manufacturing fine patterns, the fine patterns are introduced into the manufacturing of the electroluminescent back electrode, and the conductive ink with the conductive material is spray painted on the surface of the dielectric layer in a spray painting mode, so that the complex electrode patterns can be manufactured.

Detailed Description
The principles and features of this invention are described below in conjunction with examples which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
The UV spray painting ink is used for manufacturing patterns on a back electrode of an electroluminescent device; the UV spray painting ink is sprayed and painted on the electroluminescent back electrode in a spray painting mode, so that complex electrode patterns can be manufactured.
The UV spray painting ink comprises the following components in parts by weight: 5-15 parts of UV prepolymer, 50-90 parts of UV monomer, 0.5-2 parts of dispersant, 0.5-2 parts of photoinitiator and 3-10 parts of conductive material; compared with solvent type ink and water-based ink, the UV spray painting ink does not contain volatile solvent, has low requirement on base materials, can instantly dry a coating film, saves energy, and has good abrasion resistance, light resistance, weather resistance and water resistance after being cured.
Preferably, the UV spray-painting ink comprises the following components in percentage by mass: 12 parts of UV prepolymer, 80 parts of UV monomer, 1 part of dispersant, 1 part of photoinitiator and 4 parts of conductive material.
Preferably, the detergent also comprises a surfactant, and the mass part of the surfactant is 0.5-3 parts.

Preferably, the UV monomer includes a monofunctional acrylate component and/or a difunctional acrylate component; the UV monomer mainly reduces viscosity, and enables the UV spray printing ink to have good operability and adjustability in spray painting patterns.
Preferably, a monofunctional acrylate component and/or a difunctional acrylate component; wherein, the monofunctional acrylate component comprises one or more of isooctyl acrylate, octadecyl acrylate, isobornyl acrylate, 2 (2-ethoxy) ethyl acrylate, dodecyl methacrylate and tetrahydrofuran methacrylate; the difunctional acrylate component comprises one or more of triethylene glycol dimethacrylate, neopentyl glycol dimethacrylate, tetraethylene glycol dimethacrylate, 1, 4-butanediol diacrylate, 1, 6-hexanediol diacrylate polyethylene glycol (200) dimethacrylate.

Preferably, the conductive material is one of silver nanowires, conductive polymers, graphene and carbon nanotubes.
Preferably, the photoinitiator is one or more of 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl acetone, 2,4, 6-trimethylbenzoyl-diphenyl phosphine oxide and phenyl bis (2,4, 6-trimethylbenzoyl) phosphorus oxide.
The manufacturing method of the UV spray painting ink comprises the following steps of firstly adding the UV prepolymer, the UV monomer, the surfactant, the dispersant and the conductive material into a beaker, stirring for 2 hours, then adding the photoinitiator, and stirring for 30 minutes.
The back electrode of the electroluminescent device is provided with patterns, and the patterns are formed by UV (ultraviolet) spray painting ink in a spray painting mode.
The technical solution of the present invention will be described below with specific examples.
Whether the pattern on the back electrode of the electroluminescent device has good effect can be judged by the sheet resistance of the pattern. Specifically, when the sheet resistance of the thin film pattern is large, it is considered that the thin film pattern is difficult to be uniformly connected, indicating that lines on the pattern may be broken; and when the sheet resistance of the pattern is smaller, the lines of the pattern are well connected.
Before the pattern of the UV spray painting ink spray painting is measured, the same pattern is respectively drawn on the back electrodes of the electroluminescent devices by adopting a coating process and an etching process which have good effects but high cost, and after the pattern is drawn, the sheet resistance of the pattern is respectively measured, so that the sheet resistance of the pattern of the back electrode device with good display effect is 40-60 omega/□, and therefore, the back electrode pattern with the sheet resistance in the range can be considered to have good effects.
The specific formula of the UV spray printing ink of the embodiments 1-3 and the comparative examples 1-2 of the invention and the sheet resistance of the sprayed film pattern are shown in Table 1:
TABLE 1 formulas and sprayed film pattern sheet resistances of examples 1-3 and comparative examples 1-2
According to the above table, the sheet resistance values of the film patterns of the UV inkjet printing inks of examples 1 to 3 are all in the range of 40 to 60 Ω/□, and it can be determined that the lines of the film patterns are continuous and fine, so that the display effect is good. The sheet resistance of the film pattern of comparative example 1 was greater than 500 Ω/□, that is, the line breakage in the film pattern of comparative example 1 was more, the silver nanowires were not uniformly dispersed, and the effect was poor. The UV inkjet ink of comparative example 2 could not form a thin film, and it was difficult to pattern the back electrode. The results of the above examples and comparative examples prove that the UV spray printing ink can be used for manufacturing back electrode patterns of electroluminescent devices, and the thin film patterns manufactured by the UV spray printing ink have the advantages of clear and continuous lines and good display effect.
