About the manufacture method of above-mentioned Touch Screen, sequentially roughly comprise the making of the first shielding layer 3, the making of the making of the second shielding layer 4, sensor circuit layer 5 and the making of signal transport layer 6.
The mode of manufacturing the first shielding layer 3 is as follows: first, surperficial 21 spin coating one deck photoresistances under cover plate 2, then photoresistance is carried out to soft baking, and enter an exposure machine and expose, again cover plate 2 and photoresistance are immersed in a developer solution subsequently, the meeting moulding at this moment of the first shielding layer 3 and two the first patterns 311 is and then taken out cover plate 2 and photoresistance and firmly toasts in developer solution.
After the first shielding layer 3 completes, can utilize sputter process by transparent conductive material sputter to surface 21 under cover plate 2, then utilize micro-photographing process and etch process to define the electrode shape of sensor circuit layer 5.
The making of signal transport layer 6 can utilize sputter process by metal material sputter to surface 21 under cover plate 2, then utilize micro-photographing process and etch process to define the electrode shape of signal transport layer 6, also or in the process of above-mentioned making sensor circuit layer 5, utilize micro-photographing process and etch process once to define together the electrode shape of sensor circuit layer 5 and signal transport layer 6.
Finally, can make the second shielding layer 4 and two the second patterns 421 by printing process.Now, the second pattern 421 has formed, and respectively position in the first accommodation space 312 of the first shielding layer 3, the icon (icon) that the second pattern 421 is and indicates homepage Touch control key on Touch Screen, returns to the touch controllable function keys such as Touch control key, windows exchange key.And because the second pattern 421 is hollow out, therefore can allow light penetrate or further at this place, insert ink, the resin material of particular color from this, to show the target position of publishing picture.
As previously mentioned, because sensor circuit layer 5 needs to be electrically connected to signal transport layer 6, and in manufacture process, also can utilize micro-photographing process and etch process to define the electrode shape of sensor circuit layer 5 and signal transport layer 6 simultaneously, therefore 5 meeting of sensor circuit layer need to be by cover plate 2 across to the first shielding layer 3, yet if the thickness of the first shielding layer 3 is blocked up, can cause sensor circuit layer 5 in the intersection fracture of cover plate 2 and the first shielding layer 3, cause touch controllable function extremely and yield decline.Therefore, the material behavior demand of manufacturing the first shielding layer 3 is will be after being applied to cover plate 2, the thickness of the first shielding layer 3 can not be blocked up in order to avoid 5 fracture of sensor circuit layer, and the material behavior that photoresistance viscosity is little, mobility is large, the first shielding layer 3 is fabricated into after cover plate 2 by photoresistance, its thickness can be not blocked up and can be avoided the breakage problem of sensor circuit layer 5, so the present embodiment selects photoresistance as the making material of the first shielding layer 3.And the second shielding layer 4 is to transmit after 6 at sensor circuit layer 5 and signal on manufacturing sequence, because now sensor circuit layer 5 and signal transmission 6 has been shaped, do not need to consider the thickness problem of the second shielding layer 4, only need to select preferably material of shaded effect, therefore although the material behavior of ink is that viscosity is large, mobility is little and is suitable for the making compared with thick structure, but because its shaded effect is good compared with photoresistance, the present embodiment selects ink as the making material of the second shielding layer 4.
Yet, also just because of the material behavior of photoresistance to be viscosity little, mobility is large, if the pattern therefore forming on the first shielding layer 3 has geometry angle 423 that is similar to the second pattern 421 to exist, after the step of firmly toasting, can produce herein gauffer.But because the external form of first pattern 311 of the present embodiment is rounded, the shape of oval or other tool circular arc external forms, and without the existence that is similar to the geometry angle 423 of the second pattern 421, therefore after the step of hard baking, there will not be gauffer, and can keep the flatness on the first pattern 311 surfaces.Good flatness, except not affecting the product appearance of Touch Screen, has also avoided being formed on the dysfunction that the signal transport layer 6 on the first pattern 311 causes because of uneven surface simultaneously.In addition, the successive process of production Touch Screen can not cause because of gauffer flatness and functional abnormal yet.
Consult Fig. 8 and Fig. 9, the shape that the second embodiment of the utility model Touch Screen is each the first pattern 311 with the difference of the first embodiment is similar in appearance to the second corresponding pattern 421, and each first pattern 311 has a plurality of circular arc line segments 313, a plurality of mutually disjoint and be parallel to respectively the first straight-line segment 314 of the second straight-line segment 422 of the second pattern 421, and one by the first straight-line segment 314 and circular arc line segment 313 around the second accommodation space 315 defining.Each second accommodation space 315 by the second pattern 421 around interior, and the geometry angle 423 of the second pattern 421 around region by being covered by around region of the circular arc line segment 313 of the first pattern 311.And each first straight-line segment 314 of the first pattern 311 is greater than 0.5 millimeter with the better distance D between the second corresponding straight-line segment 422, and the better radius of curvature R 2 of each circular arc line segment 313 of the first pattern 311 is greater than 0.5 millimeter.Through actual production checking, learn, the first pattern 311 and the tolerance standard of the second pattern 421 in manufacturing process can be fully reserved in selecting on the one hand of this radius-of-curvature, guarantee to produce yield; On the other hand, can so that the first pattern 311 around region and the second pattern 421, reach best matching effect, eliminate due to the first pattern 311 with the second pattern 421 due to shape and the sight equation that brings of varying in size different in nature.
Because the position at the geometry angle 423 of corresponding the second straight-line segment 422 of the first pattern 311 is circular arc line segment 313, and there is no the existence at similar how much angles 423, therefore can't there is gauffer in the first pattern 311 after the step of hard baking, thereby there is effect as identical in the first above-mentioned embodiment, and feature, material behavior and the making step of all the other each parts of the second embodiment are similar to the first above-mentioned embodiment, therefore repeat no more.
Consult Figure 10, the 3rd embodiment of the utility model Touch Screen is that with the difference of the second embodiment the first straight-line segment 314 and the second corresponding straight-line segment 422 vertical projection patterns overlap, and the geometry angle 423 of corresponding the second straight-line segment 422 still, the position of the circular arc line segment 313 of the first pattern 311, and the better radius of curvature R 3 of each circular arc line segment 313 of the first pattern 311 is greater than 0.5 millimeter, therefore, the first pattern 311 also there will not be gauffer after the step of hard baking, thereby there is effect as identical in the second above-mentioned embodiment, and the feature of the 3rd all the other each parts of embodiment, material behavior and making step are similar to the second above-mentioned embodiment, therefore repeat no more.
In sum, the utility model Touch Screen sees through and to make the first pattern 311 rounded, oval or have a type outside circular arc, or allow the second pattern 421 geometry angle 423 around region by being covered by around region of the circular arc line segment 313 of this first pattern 311, all can avoid the first pattern 311 to produce fold after the step of hard baking, make the first shielding layer 3 there is preferably planarization and pattern integrity, therefore really can reach the object of the utility model.
