Background technology
As shown in Figure 1, 2, electronic installation 100(such as display unit) generally there is protective layer 10(such as cover glass).The submarginal region of inner surface 11 towards electronic installation 100 inside of protective layer 10 scribbles ink 13 in case leak-stopping light.Ink 13 is generally sandwich construction, its thickness can reach 40 microns (μm), in ink 13 one end near the center of inner surface 11, between every two-layer ink, away from inner surface 11 upper strata ink relatively near lower floor's ink of inner surface 11 to the edge direction indentation of inner surface 11, thus form step.Inner surface 11 is bonded with glue-line 15.Protective layer 10 such as, is connected by the element (scheming not show, inductive layer or display floater) of glue-line 15 with electronic installation 100 inside.When assembling, glue-line 15 is generally fit in gradually on inner surface 11 according to the order from center to edge.The height protruded due to ink 13 opposite inner face 11 is higher, when glue-line 15 is bonded on inner surface 11, do not having the region of inking and scribbling the intersection in region of ink 13, the space existed between glue-line 15 and inner surface 11 is comparatively large, and due to glue-line 15 contact with the one deck in ink 13 time, with flood ink contact while of being, space will be shut like this, cause gas to discharge, like this, will bubble be packaged with between glue-line 15 and ink 13, cause assembly failure.
Summary of the invention
In view of this, be necessary to provide a kind of electronic installation solved the problem.
A kind of electronic installation; comprise protective layer; this protective layer comprises inner surface; the submarginal part of this inner surface is coated with ink; this ink encloses visible area; this ink comprises the first ink layer, the second ink layer and the 3rd ink layer that stack gradually from this inner surface, and this second ink layer and the 3rd ink layer this first ink layer relative are to the direction indentation away from this visible area.This first ink layer comprises the first inner edge, and this second ink layer comprises the second inner edge, and the 3rd ink layer comprises the 3rd inner edge, this second inner edge and the 3rd inner edge undulate, and the wave-like of this second inner edge and the 3rd inner edge is interlaced with each other.
Due to the second inner edge and the 3rd inner edge undulate, when glue-line contacts with the second inner edge or the 3rd inner edge in laminating process, be that first and corrugated crest contacts, now air can be escaped from from corrugated trough, reduces the probability that bubble produces; And due to the wave-like of this second inner edge and the 3rd inner edge interlaced with each other, reduce the ink thickness at visible area edge, reduce further bubble produce probability.

Detailed description of the invention
Refer to Fig. 3, there is disclosed the electronic installation 200 of the present invention one first embodiment, in the present embodiment, this electronic installation 200 is an intelligent mobile phone with touch-screen.This electronic installation 200 comprises housing 20 and a protective layer 30, and this housing 20 is formed with an opening 21, and this protective layer 30 is arranged in this opening.In the present embodiment, this protective layer 30 is clear glass.In other embodiments, this protective layer 30 also can be other materials, such as transparent resin etc.
Please refer to Fig. 4, this protective layer 30 comprises one towards the inner surface 31 of electronic installation 200 inside, and this submarginal region of inner surface 31 is coated with ink 40, and because protective layer 30 is clear glass, therefore this ink 40 is also visible from electronic installation 200 outside.This ink 40 encloses a visible area 50.In the present embodiment, this ink 40 is white ink or light color inks, and in other embodiments, this ink 40 also can be other ink, such as black ink.
Please refer to Fig. 5, Fig. 6, Fig. 7, Fig. 8, this ink 40 is sandwich construction, comprises the first ink layer 41, second ink layer 43 and the 3rd ink layer 45 that stack gradually from inner surface 31.
This first ink layer 41 is coated on inner surface 31, comprises first inner edge 410 and of a contiguous visible area 50 away from outside first of visible area 50 411.This is 411 concordant with the edge of this protective layer 30 outside first.This first inner edge 410 is straight line.The shape of this first ink layer 41 determines the shape of the ink 40 being presented in electronic installation 200 outside.Because this first inner edge 410 is straight line, therefore look from the outside of electronic installation 200, this ink 40 has linear edge, and there will not be irregular phenomenon.
This second ink layer 43 is coated on this first ink layer 41, and the 3rd ink layer 45 is coated on this second ink layer 43.This second ink layer 43, the 3rd ink layer 45 this first ink layer 41 relative are to the direction indentation away from visible area 50.This second ink layer 43 comprises second inner edge 430 and of a contiguous visible area 50 away from outside second of visible area 50 431,3rd ink layer 45 comprises the 3rd inner edge 450 and of a contiguous visible area 50 away from outside the 3rd of visible area 50 the 451, and this is 451 concordant with the edge of this inner surface 31 outside the 431, the 3rd outside second.
This second inner edge 430 and the 3rd inner edge 450 are in wavy.This second inner edge 430 comprises primary peak 433 and the first trough the 435, three inner edge 450 comprises secondary peak 453 and the second trough 455.This primary peak 433 equals the distance of this secondary peak 453 to this first inner edge 410 to the distance of this first inner edge 410.The wave-like of this second inner edge 430 and the 3rd inner edge 450 is interlaced with each other, and in the present embodiment, this primary peak 433 is positioned at this second trough 455 place, and this secondary peak 453 is positioned at this first trough 435 place.
Because the wave-like of this second inner edge 430 and the 3rd inner edge 450 is interlaced with each other, therefore on this first ink layer 41, at this primary peak 433 and this secondary peak 453 place, only have one deck second ink layer 43 or the 3rd ink layer 45, thus reduce the thickness of ink 40 herein, also just decrease when glue-line (figure does not show, is optical clear glue-line in the present invention) is adhered to inner surface 31, space between glue-line and ink 40, thus the probability decreasing bubble generation.In addition, due to the second ink layer 43 and the second inner edge 430 of the 3rd ink layer 45 and the shape of the 3rd inner edge 450 have recessed have convex, when fitting, primary peak 433 and secondary peak 453 contacted with glue-line (with reference to figure 6, Fig. 7) before this, be that the confluce of the second inner edge 430 and the 3rd inner edge 450 contacts with glue-line (with reference to figure 8) again, namely the second ink layer 43 and the 3rd ink layer 45 can not just be shut by glue-line quickly completely.Such gas can be escaped from from the confluce of the second inner edge 430 and the 3rd inner edge 450, thus reduce further the probability of bubble generation.
Please refer to Fig. 9 to Figure 13, there is disclosed the electronic installation 300 of second embodiment of the invention, this electronic installation 300 is substantially identical with electronic installation 200, unlike, the ink 40 of this electronic installation 300 also comprises one the 4th ink layer 47.4th ink layer 47 is coated on the 3rd ink layer 45.4th ink layer 47 and the second ink layer 43, the 3rd ink layer 45 basic simlarity, comprise one in wavy 4th inner edge 470.4th inner edge 470 comprises the 3rd crest 473 and the 3rd trough 475.3rd crest 473 is positioned at the first trough 435 and the second trough 455 place, and the 3rd trough 475 is positioned at this primary peak 433 or secondary peak 453 place.
The invention is not restricted to disclosed by above-mentioned two embodiments, such as, the present invention can also comprise more ink layer, as long as except the first ink layer, the corrugated inner edge of other ink layeies is interlaced with each other.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
