Fig. 2A show a kind of embodiment such as Figure 1B touch panels fragmentary cross-sectional view (along Figure 1B double arrows 130 it
Section), wherein touch panel 200 includes a substrate 201, and the side of substrate is provided with a shielding layer 202, and shielding layer 202 is set
Region is set, the non-visible area domain of touch panel 200 is defined；On the surface (homonymy with shielding layer 202) of substrate 201, setting
There is sensing electrode layer 203, in this example, sensing electrode layer 203 crosses the visible area of touch panel 200, across shielding layer 202
Side wall, and contacted with the signal lead layer 204 of 202 top of shielding layer, therefore the transparent sensing electricity in sensing electrode layer 203
Pole can be connected with the plural metal lead wire in signal lead layer 204；It is apparent that shielding layer 202 is arranged in signal lead layer
204 lower section can play the role of the sight for stopping user, to visually draw the metal in signal lead layer 204
Line concealing promotes 200 beauty from integral formation sight degree of touch panel.In general, the material of shielding layer 202 is photoresist or ink.
In this embodiment, since sensing electrode layer 203 can be crossed on the side wall of shielding layer 202.Therefore it is required that masking
Otherwise 202 maximum thickness of layer can cause sensing electrode layer 203 can be because the brittleness of its material itself causes no more than 25um
Climbing breakage problem, so as to cause the electrical open circuit problem of sensing electrode layer 203.
However it is covered in layer material in use, under the long-time exposure of ultraviolet light 210 in nature in touch panel
Organic substance (such as resin) polymerisation can occur, lead to problems such as the opacity of shielding layer decline (decline of OD values),
It is referred to as aging phenomenon in the industry；On the other hand, in order to test tolerance degree of the touch panel for ultraviolet light, touch panel is being made
Also include that ultraviolet light and aging is tested in the flow of work, with the ultraviolet light touch panel of high dose；Therefore, it is whether making
When ultraviolet light and aging test or normal use in, ultraviolet light may destroy shielding layer.
Therefore in the touch panel of first embodiment of the invention, increase by one anti-aging layer of setting, to absorb or reflect
Ultraviolet light.As shown in Figure 2 B, touch panel 200 includes substrate 201, shielding layer 202, sensing electrode layer 203, signal lead layer
204, wherein between shielding layer 202 and substrate 201, it is another that an anti-aging layer 205 is set, to prevent shielding layer 202 because ultraviolet
The aging of light generation.In fig. 2b, anti-aging layer 205 only covers the non-visible area of touch panel, thus anti-aging layer 205 for
Can be transparent or opaque material for visible light.At this time if the structure of sensing electrode layer 203 needs to cross over shielding layer
202 side wall, and contacted with the signal lead layer 204 of 202 top of shielding layer (as Fig. 2A is shown), then it must take into account anti-
The 203 climbing difficulty of sensing electrode layer that there are problems that causing of aging layer 205 increases.Therefore, anti-aging in present embodiment
205 preferred thickness range of layer are less than 5 μm~21 μm, and reason is：
1, since the maximum climbing height of sensing electrode layer 203 is 25 μm.And the opacity (OD values) of different shielding layers
Difference as long as 4um plays enough screening effects when shielding layer 202 is made of black ink, and works as shielding layer
202 then want 20um or so just using white ink enough screening effects；Thus can deduce, 205 thickness range of anti-aging layer
It is 5 μm~21 μm；
2, it is verified it is found that when the thickness of anti-aging layer 205 is less than 5 μm, cannot be got preferable anti-according to actual production
Aging effect.
In addition, anti-aging layer 205 can to resist with by adding colorant or carbon dust etc. in a better embodiment
The color of aging layer 205 is identical as the color of shielding layer 202, thereby, can increase shielding layer 202 by anti-aging layer 205
Opacity, so as to reduce the thickness requirement of shielding layer 202, and then the maximum climbing for reducing sensing electrode layer 203 is high
Degree.
From the above, anti-aging layer 205 may include the material for reflecting ultraviolet light, such as nanometer grade alundum (Al2O3)
(Al2O3), magnesia (MgO), zinc oxide (ZnO), titanium dioxide (TiO2), kaolin, zinc oxide, silica or above-mentioned material
The mixture of material；Anti-aging layer 205 also may include absorbing the material for penetrating ultraviolet light, such as salicylic acid ester type compound, hexichol first
Ketone compounds, azimidobenzene class compound, substitution compound in triazine class, group-substituted acrylonitrile compound or above-mentioned material are mixed
Close object.
And in another state sample implementation, anti-aging layer 205 is transparent material for visible light, therefore anti-aging layer
205 can cover the visible area and non-visible area of touch panel simultaneously, as shown in Figure 2 C.In present embodiment, when using upper
When stating material of the organic compound as anti-aging layer 205, since the adhesive force of organic compound is relatively good, it is coated on base
When the upper surface of plate 201, increase adhesive force can be played to the formation of the sensing electrode layer 203 or shielding layer 202 of upper side
Effect.In another state sample implementation, as shown in Figure 2 D, anti-aging layer 205 is located at the another of substrate 201 with respect to shielding layer 202
Side；Similarly, in figure 2d, anti-aging layer 205 covers the visible area and non-visible area of touch panel 200 simultaneously, therefore anti-ageing
Change the material that layer 205 is transparent for visible light, but the present invention is also not excluded for anti-aging layer 205 and only covers touch panel
200 non-visible area；In another state sample implementation, as shown in Figure 2 E, anti-aging layer 205 is arranged in the lower surface of substrate 201,
Only cover the non-visible area of touch panel.At this time since anti-aging layer 205 is formed in the side that substrate 201 is closer to user
On, and it is not that whole face is formed on substrate 201, it is therefore necessary in view of the presence of anti-aging layer 205 may cause user
The problems such as visual discomfort.Therefore, 205 preferred thickness range of anti-aging layer is 5 μm~10 μm in present embodiment, and reason exists
In：
1, visually in view of human eye angle of minimum resolution is about 10um, therefore the thickness of anti-aging layer 205 is less than 10um
When, it can not be perceived by the human eye；
2, it is verified it is found that when the thickness of anti-aging layer 205 is less than 5 μm, cannot be got preferable anti-according to actual production
Aging effect.
Fig. 3 A show another embodiment of the present invention, and touch panel 300 includes substrate 301, shielding layer 302, sensing electricity
Pole layer 303, signal lead layer 304 are provided with an anti-aging layer 305 wherein between shielding layer 302 and substrate 301；This is implemented

Fig. 5 show a further embodiment of the present invention, the part of the display such as another embodiment of Figure 1B touch panels
Sectional view (sections of double arrows 140 along Figure 1B)；In the present embodiment, touch panel 500 hides comprising substrate 501, first
Cover a layer 502A, sensing electrode layer 503, signal lead layer 504, the second shielding layer 502B and anti-aging layer 505；Itself and aforementioned each reality
The main difference for applying mode is that this structure has two layers of shielding layer, and be arranged two layers shielding layer the reason is that, shown in Fig. 5
Structure in, sensing electrode layer 503 crosses the visible area of touch panel 500, across the side wall of the first shielding layer 502A, and with letter
Number trace layer 504 contacts so that the transparent sensing electrode in sensing electrode layer 503, it can be with the plural item in signal lead layer 504
Metal lead wire is connected；In this structure, if the first shielding layer 502A is blocked up, sensing electrode layer 503 crosses over the first shielding layer
The part of 502A side walls is easy to be broken in the production process, influences the yield of 500 making of touch panel, it is therefore desirable to reduce first
The thickness of shielding layer 502A.
But the thickness on the other hand, reducing by the first shielding layer 502A will at least bring both sides technical difficulty.First
The rear system of touch panel 500 have a back light 520, if therefore the first shielding layer 502A thickness it is too thin, in backlight light
Under the irradiation in source, the metal lead wire in signal lead layer 504 can still be seen by the user of panel；Second shielding layer 502B's sets
Set as overcome the problems, such as this one, to block the back light of panel；In general actual application, the second shielding layer 502B is needed
It is thicker than the first shielding layer 502A, therefore the second shielding layer is usually made with viscosity higher material, such as viscosity range
Between the ink of 4000cps to 12000cps, and the first shielding layer is usually made with the relatively low material of viscosity, such as viscosity model
The photoresist between 4cps to 30cps is enclosed, which is because, being limited to existing processing procedure, when the viscosity of material is bigger, after coating
The thickness of formation is bigger.Practice finds that if the material viscosity of the first shielding layer 502A is more than 30cps, it can cause to be formed by
The thickness for covering layer thickness is more than 25 μm, to the limitation of the maximum climbing height more than sensing electrode layer.Knot shown in Fig. 5
In structure, the second shielding layer includes a notch 502C to form a bonding land (i.e. region 112 in Figure 1B), signal lead layer 504
In each metal lead wire, one end is electrically connected at the sensing electrode layer 503, and the other end converges to the bonding land, through this
Bonding land is then connected to a flexible printed wiring board (not shown).
From the above, another harmful effect for reducing by the first shielding layer 502A thickness, after being that thickness reduces, ultraviolet light
510 the effects such as reduce for the yellow caused by the first shielding layer 502A, transparency will become apparent from, therefore anti-aging layer 505
Setting it is even more important.In this embodiment, the material of anti-aging layer 505, position are similar with the respective embodiments described above；
In Fig. 5, anti-aging layer 505 is set between substrate 501 and the first shielding layer 502A, but anti-aging in other state sample implementations
Layer 505 can also be located at the other side of substrate 501 with respect to the first shielding layer 502A；In addition in terms of the range of covering, anti-aging layer
505 can cover the visible area and invisible range of touch panel 500 simultaneously, also can only be covered in the not visible of touch panel 500
Area, in most extreme example, anti-aging layer 505, which only covers the structure for being intended to cover in 500 invisible range of touch panel, most to be held
The part of easy exposing, i.e. anti-aging layer 505 only cover the bonding land that notch 502C is formed, and (only the first shielding layer 502A has it
Bridging effect).
The present invention provides the touch panel for including anti-aging layer, on the one hand makes the non-visible area of touch panel will not be because of system
Ageing resistance by ultraviolet light test during work, and yellow occurs, opacity declines and exposes and be intended to the structure covered, destroy tactile
It controls screen beauty from integral formation to see, on the other hand, the setting of the anti-aging layer also increases touch panel in actual use, for environment
The resistivity of middle ultraviolet light can extend the service life of touch panel.
Example the above is only the implementation of the present invention is not limited to the scope of patent protection of the present invention.It is any ripe
Practise alike those skilled in the art, do not departing from spirit and scope of the invention, made by change and retouching equivalence replacement, be still this hair
In bright scope of patent protection.
