Embodiment 1

[0035] Example 1: To 25 parts by weight of urethane acrylate resin, add 15 parts by weight of hydrogen furfuryl acrylate, 18 parts by weight of propylene glycol methyl ether, 30 parts by weight of ethyl acetate, and 0.5 parts by weight of modified polydimethyloxane solution. Parts by weight, 1.5 parts by weight of modified organosiloxane polymer, 4 parts by weight of SIO2 particles, 0.5% of 50nm carbon black, after stirring evenly, add 6 parts by weight of lencolo5006 general-purpose photoinitiator 184, stir evenly, and obtain a coating liquid.

[0036] Coating the prepared coating solution on one side of the cellulose triacetate TAC substrate with a thickness of 60um, the coating thickness is 3-5um, the baking temperature is 80°C / 2min, and the UV curing condition is 500-700mj / cm2 UV radiation dose, test The properties of the relevant coating fluids are shown in Table 1.

Embodiment 2

[0037] Embodiment two: in the special modified pure acrylate resin of 30 weight parts, add 15 weight parts of hexanediol diacrylate, 15 weight parts of ethyl acetate, 25 weight parts of toluene, modified polydimethyloxane 0.8 parts by weight of solution, 1.2 parts by weight of modified organosiloxane polymer, 4 parts by weight of PMMA particles, 1.5% of 70nm carbon black, after stirring evenly, add 9 parts by weight of lencolo 5022 754 photoinitiator, stir evenly, and obtain the coating cloth liquid.

[0038] Coating the prepared coating liquid on one side of the cellulose triacetate TAC substrate with a thickness of 60um, the coating thickness is 4-6um, the baking temperature is 80°C / 1.5min, and the UV curing condition is 400-600mj / cm2 UV irradiation dose, The performance of the relevant coating liquids was tested, and the results are shown in Table 1.

[0039] Such as figure 2 , the outermost layer of the anti-reflection absorbing layer is a low-refractive-index film laye...

Embodiment 3

[0041] Embodiment three: the thickness of the first low refractive index SIO2 film layer is 75~95nm, the thickness of the first high refractive index Nb2O5 film layer is 95~115nm, the thickness of the second low refractive index SIO2 film layer is 30~45nm, the second The thickness of the second high refractive index Nb2O5 film layer is 7-15nm, the thickness of the third low refractive index SIO2 film layer is 30-45nm, and the reflectivity is <0.6%. The test results are shown in Table 2

Abstract

The invention discloses a diaphragm with an integrated black display effect, which comprises a release film, an adhesive layer, a base material, a semi-transparent anti-dazzle layer, an antireflection layer and an anti-fingerprint layer, the adhesive layer is arranged on the back of the base material, the release film is pasted on the adhesive layer, the semi-transparent anti-dazzle layer is prepared on the front of the base material through a coating process, the anti-reflection absorption layer is arranged on the semi-transparent anti-dazzle layer through a roll-to-roll process, and the anti-fingerprint layer is prepared on the anti-reflection layer in a coating mode. According to the invention, the coating mode is similar to that of a directly used semi-transparent material, the hardened layer with the nano black pigment is coated on the surface of the base material, so that the base material is semi-transparent, and the surface reflectivity of the screen is reduced in combination with coating, so that the screen effect is better.

Description

Technical field: [0001] The invention relates to the technical field of display screens, in particular to a diaphragm with an integrated black display effect. Background technique: [0002] With the improvement of consumers' aesthetics, everyone's pursuit of aesthetics is getting higher and higher. However, when most display screens are in the off-screen state, there is a clear color difference between the display area and the edge ink area, and the visual effect is poor. The "integrated black" can make it difficult to distinguish the color difference between the display area and the edge ink area of ​​the display screen with the naked eye, and create a seamless visual impression, making the product appearance more high-end, atmospheric, beautiful and technological. Product differentiation, thereby increasing consumers' desire to buy. In addition to vehicle display, it is also widely used in smart terminals such as smart phones, smart wearables, and mid-to-high-end touch pe...
