Specific embodiment

In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein It applies example to be only used to explain the utility model, is not used to limit the utility model.

It should be noted that it can be directly another when element is referred to as " being fixed on " or " being set to " another element On one element or indirectly on another element.When an element is known as " being connected to " another element, it can To be directly to another element or be indirectly connected on another element.

Referring to Fig. 1, existing be illustrated 2.5D cover board provided by the utility model.A kind of 2.5D cover board is provided, including Acrylic ontology 1, acrylic ontology 1 include flat part 11 and the first angle 2.5D 12, and the inside at the first angle 2.5D 12 is connected to flat The outer rim in plate portion 11 further includes the first hardened layer 2 and the second hardened layer 3, and the first hardened layer 2 is set to the upper surface of flat part 11, And hardened layer all standing flat part 11；Second hardened layer 3 is set to the upper surface of the first hardened layer 2, and the edge of the second hardened layer 3 Extend outwardly and covers the first angle 2.5D 12；The outside of second hardened layer 3 is equipped with the 2nd angle 2.5D 31.

Compared with prior art, 2.5D cover board provided by the utility model include acrylic ontology 1, the first angle 2.5D 12, First hardened layer 2 and the second hardened layer 3 enhance the hardness on 11 surface of flat part by the first hardened layer 2；Pass through the second hardening The design of layer 3, makes more to coordinate at 12 position of the first angle 2.5D with surface, eliminates break bar print, increases water droplet angle, simultaneously, moreover it is possible to right Marginal position stiffened again, prevents lid surface to be scraped off.

Further, referring to Fig. 1, the aligned inside of the outer rim of the first hardened layer 2 and the first angle 2.5D 12；Make cover board table The hardness in face is reinforced, and prevents from being scratched.

Further, referring to Fig. 1, the outside at the 2nd angle 2.5D 31 covering the first angle 2.5D 12 and the first hardened layer 2；Make It is connected rounder and more smooth with surface at 12 position of the angle 2.5D, increases water droplet angle, has more aesthetic feeling, while can also play and prevent finger line Effect.

Further, referring to Fig. 1, the outer rim at the 2nd angle 2.5D 31 is concordant with the outer rim at the first angle 2.5D 12.It hardens At first angle 2.5D, 12 position, the break bar print at 12 position of the first angle 2.5D is eliminated, finger line can be prevented.

Further, the first hardened layer 2 with a thickness of 3-5um, the second hardened layer 3 with a thickness of 3-10um；First hardening The thickness of layer 2 can guarantee service performance between 3-5um；If thickness is excessive, the first hardened layer 2 is made to be piled up in the of both sides At one angle 2.5D, 12 position, and thickness is excessive, can not achieve uniform coating, wastes raw material；If too thin, hardness number is inadequate, no It can effectively prevent from scratching；The design of the thickness of second hardened layer 3 also has effect so.

Further, dyne value on 2 surface of the first hardened layer is greater than 36 dynes, and dyne value on 3 surface of the second hardened layer is small In 30 dynes；Dyne value on 2 surface of the first hardened layer is greater than 36 dynes, during coating, is easy the first hardened layer 2 attached In the upper of cover board；Dyne value on 3 surface of the second hardened layer less than 30 dynes, can make the second hardened layer 3 it is firm be attached to the On one hardened layer 2, prevents the first hardened layer 2 from falling off, guarantee the persistence used.

Further, the hardness of the first hardened layer 2 is greater than 1H, and the hardness of the second hardened layer 3 is greater than 4H；First hardened layer 2 Hardness be greater than 1H, the hardness of lid surface can be enhanced；In addition, the hardness of the second hardened layer 3 is greater than 4H, lid can be further strengthened The hardness of plate surface, simultaneously, moreover it is possible to enhance the hardness at 12 position of the first angle 2.5D of cover board, it is hard for the cover board after stiffened Du Genggao, wearability are more preferable, moreover it is possible to play the role of preventing finger line.

Further, the first hardened layer 2 is coated on the upper surface of flat part 11；By way of coating, by the first hardening Layer 2 is coated on the upper surface of flat part 11, easy to operate and practical.

Further, the second hardened layer 3 prints on the upper surface and the first angle 2.5D of the first hardened layer 2 by 3D printer 12 upper surface.Since the edge at the first angle 2.5D 12 is exposed outside, by 3D printer at the first exposed angle 2.5D 12 One layer of second hardened layer 3 is printed at position, eliminates break bar print, increases the hardness number at this, and the mode printed can make first The angle 2.5D forms good globoidal structure at 12 position, and external form is more preferable.

Further, acrylic ontology 1 is PMMA ontology or PC ontology；PMMA and PC is transparent material, and is had good Good chemical stability.

Electronic display, including display screen main body are connected with 2.5D cover board above-mentioned in display screen main body；Comprising aforementioned The electronic display of 2.5D cover board, wearability, plasticity are good, and smooth in appearance is mellow and full, can anti-finger line, and it is cheap.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
