Embodiment
Below, with reference to accompanying drawing, to of the present invention, preferred embodiment be described in detail.Size shown in this embodiment, material and other concrete numerical value etc. are only for being easier to understand the illustration of invention, and except situation about being particularly limited, the present invention is not limited thereto.In addition, in this instructions and accompanying drawing, about in fact thering is the key element of identical function, structure, give identical mark, thereby omit repeat specification, and, for the present invention, there is no the key element of direct relation, omit its diagram.
Fig. 1 is the exploded view of explanation portable set and cover glass.Portable set 100 shown in Fig. 1 is an example, and it is the touch panel machine, and possesses the large-scale cover glass 120 on the whole surface that covers basket 102.Contain display frame 106, loudspeaker 108 and the button 110 etc. of main substrate 104, liquid crystal panel or organic EL panel etc. in the basket 102 of portable set 100.In addition, the private side at cover glass 120 disposes the touch panel 112 with transparency electrode 114.Be connected with the distribution 116 formed by flexible cable in transparency electrode 114, can be connected with main substrate 104 by not shown connector.In addition, in the base material of touch panel 112, use the situation of blue or green glass sheet (soda-lime glass) more, but also can replace glass and form by the resin masking.
There is non-display area in the display frame 106 that is built in portable set 100 at edge part.And, between the sidewall of the edge of display frame 106 and basket 102, must be formed with gap.And the distribution 116 of transparency electrode 114 is disposed at the neighboring of the private side of cover glass 120.Therefore, in order to hide these non-display areas, gap, distribution etc., application 122 is set so that (outside) forms hidden regional 150(with reference to Fig. 2 around display frame 106).As the object lesson of application 122, the coating of coating black or white etc.
Herein, in the present embodiment, the roughly all-round and first type surface of private side that makes portable set that the glass substrate 130 of cover glass 120 is formed the periphery that spreads all over glass substrate 130 on peripheral direction than the master meter face length of the outer side of portable set.
Fig. 2 is the figure of the end of explanation cover glass 120.
At first, the cover glass 120a shown in Fig. 2 (a) is described.Cover glass 120a shown in Fig. 2 (a) is the example that has used the glass substrate 130a extracted from plate glass by etching.In glass substrate 130a, the top of figure is that the outer side first type surface 140a, the below that are positioned at the outer side of portable set 100 are that the private side first type surface 140b(that is positioned at private side all means scope with oblique line in the drawings).
At the peripheral end face of glass substrate 130a, spread all over all-roundly be formed with the most outstanding boundary portion 142a, from boundary portion 142a to outer side first type surface 140a and private side first type surface 140b tilt and continuous dip plane 142b and 142c.Dip plane 142b, 142c are by lysed of etchant.
Herein, in the present embodiment, private side first type surface 140b forms on peripheral direction longer than outer side first type surface 140a.And, follow in this roughly all-round and deflection that boundary portion 142a forms the periphery that spreads all over glass substrate 130a longer private side first type surface 140b side on peripheral direction.As hereinafter described, can carry out etching (longer) and form such end face than the dip plane 142c of private side first type surface 140b side is more by the dip plane 142b to outer side first type surface 140a side.
According to said structure, the most peripheral of private side first type surface 140b be formed with from outer side first type surface 140a side, can't observe not visible regional 152.As mentioned above, although form hidden regional 150 by application 122 at the private side first type surface 140b of glass substrate 130a, but due to a part become not visible regional 152, so can subdue the area of the viewing area 154 that can observe from outer side first type surface 140a side in hidden regional 150.Thus, thinner owing to can making frame be rendered as, shown in can expect to make the lifting attractive in appearance of portable set, and promote high function sense.
In addition, in the situation that hypothesis from outward appearance, observe hidden regional 150 for degree as in the past, can obtain than in the past (than the end face of cover glass being made as to the situation of vertical plane) more wide space at the private side of cover glass 120a.That is, when the width by viewing area 154 is made as with hidden regional 150 same degree in the past, can obtain at the private side of cover glass 120a will be in the past hidden regional 150 the width wide space after adding not visible regional 152 width.Therefore, the distribution 116 of nargin ground configuration transparency electrode 114 can be arranged in this space, and can promote the degree of freedom of design.
Wherein, by forming boundary portion 142a deflection longer private side first type surface 140b side on peripheral direction, due to from just from the outside of taking formula equipment 100, being difficult for observing boundary portion 142a, so preferably.
In the situation that form profile by machining as shown in Fig. 2 (b), also can form at the most peripheral of private side first type surface 140b from outer side first type surface 140a side, can't observe not visible regional 152.Thus, can subdue the area of the viewing area 154 that can observe from outer side first type surface 140a side in hidden regional 150.
Fig. 3 illustrates the figure of the cover glass that present embodiment is related from other viewpoint.In other words, can consider that above-mentioned cover glass 120a separates the distribution protection part 172 that the display frame corresponding with display frame 106 protects part 170 to extend laterally with the first type surface that makes private side on function.Herein, display frame protection part 170 be configured to comprise a pair of opposed major surfaces, by the private side display part first type surface 140c of above-mentioned outer side first type surface 140a and the scope of answering in contrast.And, distribution protection part 172 be configured to comprise private side display part first type surface 140c is further extended laterally private side wiring part first type surface 140d.In distribution protection part 172, there do not is the first type surface (for dip plane) with the opposed outer side of private side wiring part first type surface 140d.
According to said structure, can there is nargin ground to guarantee the space for the protection of distribution.If suppose cover glass section be shaped as rectangle (end face is vertical plane),, because the surface that is desirably in portable set 100 is made as the requirement in larger design as far as possible by the ratio of display frame 106 area occupied, for the space of coiling distribution 116, become extremely narrow.So the distribution 116 that exceedingly makes flexible cable is crooked and cause being difficult to assembling, or becomes by broken string or plating and split and the reason of the loose contact that causes.Yet, by by distribution protection part 172, guaranteeing space, can make the assembling of touch panel 112 become easily as described above, thereby and can prevent that broken string from promoting permanance.
In addition, as mentioned above, when the periphery of the first type surface of the private side at cover glass 120a form by application 122, is formed hidden regional 150 the time, preferably, while overlooking cover glass 120a, hidden at least a portion of regional 150 and distribution protect part 172 overlapping.Spread all over private side display part first type surface 140c and private side wiring part first type surface 140d and application is hidden regional 150, or only in private side wiring part first type surface 140d application hidden regional 150.Thus, can subdue the area (the particularly area of the viewing area 154 when the situation of forward sight portable set 100) of the viewing area that can observe from outside 154 in hidden regional 150.Thus, thinner owing to can making frame be rendered as, thus can expect to promote the attractive in appearance of portable set 100, and promote high function sense.
In addition, because the area of the Area Ratio outer side first type surface 140a of private side first type surface 140b is larger, so can guarantee that the adhesion area of the cover glass 120a relative with the basket 102 of portable set 100 or touch panel 112 is larger, thereby can improve bonding stability.And, because the area of the Area Ratio outer side first type surface 140a of private side first type surface 140b is larger, so when with finger etc., to outer side first type surface 140a side, pressing cover glass 120a, can make this pressure disperse to private side first type surface 140b side, thereby can improve the resistance to impact of portable set 100.
Fig. 4 is other the figure of configuration example of explanation cover glass.Although at Fig. 2 (a) with cover glass 120a, the 120b (b), implement application 122 until the end of private side first type surface 140b, also can be as shown in Figure 4, only in viewing area, 154 implement application 122a.In other words, also can be on the private side first type surface 140b of glass substrate 130, only at the edge from display frame 106, application 122a is implemented in the zone to the neighboring of outer side first type surface 140a.That is, at the edge part of private side first type surface 140b, with the unreal dress that applies in the nonoverlapping zone of outer side first type surface 140a (not visible regional 152).Thus, can by application 122a hidden from visual observation to scope (viewing areas 154 hidden regional 150), and the amount that can subdue the coating for implementing application 122a, thus can reduce production costs.
As mentioned above, in order to form cover glass 120(glass substrate 130) the first type surface of private side of portable set on peripheral direction than the master meter face length of the outer side of portable set, can extract by etching like that by glass substrate 130a as shown in Figure 2 (a) shows, also can carry out shape processing by machining like that by the glass substrate 130b as shown in Fig. 2 (b).Yet, preferably extract glass substrate 130a by etching like that as shown in Figure 2 (a) shows.Its reason is, because end face becomes solution plane by etching, thus can obtain non-microcracked extremely level and smooth end face, and can compare the higher physical strength of acquisition than by machining, at end face, forming gradient.Therefore, below, the operation for extract above-mentioned glass substrate 130a by etching is described.
Fig. 5 is the figure that the operation while by etching, extracting glass substrate 130a is described.At first, as shown in Fig. 5 (a), form the corrosion-resisting pattern 162 of the shade shape of the glass substrate 130a with regulation on the two sides of plate glass 160.Next, as shown in Fig. 5 (b), from the two sides of plate glass 160, start to carry out etching.The preferred Wet-type etching of engraving method (wet etching) but not dry-etching (dry etching).As long as the etchant for Wet-type etching can etching plate glass 160.For example, can use and take acid solution that hydrofluorite is principal ingredient or comprise at least one sour acid mixture in sulfuric acid, nitric acid, hydrochloric acid, hydrofluosilicic acid etc. in hydrofluorite.
If plate glass 160 is carried out to etching, not by the zone of corrosion-resisting pattern 162 shades, plate glass 160 is dissolved, forms groove 160a, 160b on two sides.In Wet-type etching, glass is by isotropically etching.Therefore, groove 160a, 160b width when the degree of depth is deepened broadens.
If proceed etching from two sides like this, final because the groove 160a of substantial middle section, 160b at thickness of slab are connected, glass substrate 130a is pulled out.Yet, in the present embodiment, as shown in Fig. 5 (c), finish halfway the etching from two sides, and carry out etching from one side (being the face of upside in the drawings).Thus, further carried out the groove 160a of etched side etched more deeply, wider, and first type surface shortens on peripheral direction.And, as shown in Fig. 5 (d), if glass substrate 130a is pulled out, at its end face, form above-mentioned boundary portion 142a and dip plane 142b, 142c.Like this, can spread all over glass substrate 130a periphery all-round and roughly adequate relief become a first type surface on peripheral direction than another master meter face length.Then, by printing the printing process of the application of stipulating, form the cover glass 120a as product.
Above, with reference to accompanying drawing, to of the present invention, preferred embodiment be illustrated, but the present invention is not limited to related example certainly.If those skilled in the art, in the category of putting down in writing in the scope of claim, can expect various modifications or fixed case, this is apparent, thereby can think that it also belongs in technical scope of the present invention certainly.
