背景技术
在现今各式消费性电子产品的市场中，个人数字助理(PDA)、移动电话(mobile Phone)、笔记本电脑(notebook)及平板计算机(tablet PC)等可携式电子产品皆已广泛的使用触控面板(touch panel)作为人机界面。此外，由于目前电子产品的设计皆以轻、薄、短、小为方向，因此在产品上无足够空间容纳如键盘、鼠标等传统输入设备，尤其在讲求人性化设计的平板计算机需求的带动下，触控面板已经一跃成为关键的零组件之一。
触控面板上大致可区分为显示区以及周边区，其中显示区中设计有触控功能来感测用户的触碰输入，而周边区则可提供设计实体按键时所需的位置。然而，触控面板的表面必须进行破孔才能配合实体按键的设计，而这不仅让触控面板失去平整性的外观效果，并且在制程上也较为复杂。
发明内容

于一变化实施例中更包含一对应位于该周边区的引线结构，电性连接该第一电极图案及该第二电极图案。
本发明另提供一种触控面板的制作方法，该触控面板被定义有相对应的一显示区及一周边区，该触控面板的制作方法的步骤包含：首先，形成一图案化遮蔽层于一上盖基板上，其中该图案化遮蔽层包含一图案化区域，并且该图案化遮蔽层的形成区域定义出该周边区，以及形成一包含一对应位于该显示区的第一电极图案及一对应位于该图案化区域的第二电极图案的感应电极层，其中该第一电极图案包含复数个第一桥接结构，该第二电极图案包含复数个第二桥接结构，并且所述的第一桥接结构材料与所述的第二桥接结构采用不同的材料。

于一变化实施例中，其中形成该感应电极层之步骤进一步包含：首先，形成该些第一桥接结构于该上盖基板，以位于该显示区，接着形成该些第二桥接结构于该图案化遮蔽层，以位于该周边区，然后涂布一绝缘层于该上盖基板、该图案化遮蔽层、该些第一桥接结构及该些第二桥接结构，再图案化该绝缘层来形成复数个孔洞，其中该些孔洞分别对应位于每一该些第一桥接结构的两端部及每一该些第二桥接结构的两端部，以曝露出所述第一桥接结构及所述第二桥接结构的部分区域，再涂布一导电层于该绝缘层及该些孔洞，最后图案化该导电层以形成沿一第一轴向平行排列的复数条位于该显示区的第一感应电极及复数条位于该周边区的第三感应电极，以及形成沿一第二轴向间隔排列的复数个位于该显示区的第二导电单元及复数个位于该周边区的第四导电单元，其中该些第二导电单元及该些第四导电单元覆盖于该些孔洞，使得相邻的两个该些第二导电单元通过所述第一桥接结构来电性连接，相邻的两个该些第四导电单元通过所述第二桥接结构来电性连接。

具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述。
为使熟习本发明所属技术领域之一般技艺者能更进一步了解本发明，下文特列举本发明之较佳实施例，并配合所附图式，详细说明本发明的构成内容及所欲达成之功效。
为了方便说明，本发明之各图式仅为示意以更容易了解本发明，其详细的比例可依照设计的需求进行调整。在文中所描述对于图形中相对组件之上下关系，在本领域之人皆应能理解其系指对象之相对位置而言，因此皆可以翻转而呈现相同之构件，此皆应同属本说明书所揭露之范围，在此容先叙明。
图1绘示本发明第一较佳实施例之触控面板的俯视图。其中，触控面板1可例如是应用于计算机、手机、相机、音响设备、车用设备等具屏幕显示功能之电子装置，并且本实施例之触控面板1是以背面俯视的视角来进行说明，所谓的背面也就是触控面板1使用时非使用者触碰的表面。如图1所示，触控面板1包含一上盖基板10、一第一电极图案20、至少一第二电极图案30以及一图案化遮蔽层(Patterned Mask Layer)50。
触控面板1被定义有相对应设置的一显示区A以及一周边区B, 周边区B可例如是设置于显示区A的至少一侧边。在本说明书的实施例中，周边区B是以设置于显示区A的四边而围绕显示区A的型态来设计。具体来讲，上述电子装置的屏幕可视区是对应位于显示区A，而图案化遮蔽层50形成在上盖基板10上的形成区域则是定义出周边区B，用以在显示区A***提供遮蔽及隐藏的作用。本实施例的图案化遮蔽层50可例如是采用不透明(如黑色光阻)材料，以印刷或涂布等方式形成。再者，本实施例的图案化遮蔽层50进一步包含一图案化区域51，并且图案化区域51中设计有至少一镂空图案51a及51b，本实施例是例如设计为返回键及首页键之按键符号的镂空图案。其中，图案化区域51中所设计的镂空图案之图形态样及数量并不限于此，实际更可依功能设计需求而包含其他如菜单键、开关键等按键符号。
第一电极图案20对应位于显示区A中，让显示区A不仅得以作为观看屏幕显示的窗口，更可用来提供屏幕操作的触控反应功能。第二电极图案30对应位于图案化遮蔽层50的图案化区域51中，让周边区B得以藉由图案化遮蔽层50的图案化区域51及对应设计的第二电极图案30来提供虚拟按键操作的触控反应功能。藉此，本实施例即可实现在触控面板1的同一面板表面上实现不同的触控反应功能。
为了更具体说明本实施例之触控面板1的迭层架构，请一并参考图2，为图1的I-I’剖面示意图。本实施例的第一电极图案20及图案化遮蔽层50是设置在上盖基板10，而第二电极图案30则是进一步设置在图案化遮蔽层50。其中，上盖基板10例如是采用玻璃之透明材料，并且由于本实施例之上盖基板110除了用来作为触控用的基板之外，更是用来作为保护用的基板, 因此上盖基板110可例如是已先经过强化、抗眩、抗菌等表面处理。
在实际制程上，第一电极图案20及第二电极图案30可例如是经由相同制程步骤而架构成一感应电极层。其中，第一电极图案20包含复数个沿第一轴向(本实施例为X轴)平行排列的第一感应电极22及复数个沿第二轴向(本实施例为Y轴)平行排列的第二感应电极24，上述的第一感应电极22及所述的第二感应电极24彼此相互绝缘。而第二电极图案30则包含复数个沿第一轴向(本实施例为X轴)平行排列的第三感应电极32及复数个沿第二轴向(本实施例为Y轴)平行排列的第四感应电极34，所述的第三感应电极32及所述的第四感应电极34是彼此绝缘。
更具体来说明，每一第一感应电极22与每一第三感应电极32分别为一连续结构，也就是说为一体成形且无间隙结构；而每一第二感应电极24包含复数个第二导电单元25及复数个第一桥接结构26；每一第四感应电极34包含复数个第四导电单元35及复数个第二桥接结构36。其中，第一感应电极22、第三感应电极32、第二导电单元25以及第四导电单元35是由同一导电层透过微影制程(Photo Lithography)来制作而成，换句话说，第一感应电极22、第三感应电极32、第二导电单元25以及第四导电单元35即属于导电层。此外，第一桥接结构26是分别跨越各第一感应电极22来电性连接第二轴向上相邻的两个第二导电单元25。第二桥接结构36是分别跨越各第三感应电极32来电性连接第二轴向上相邻的两个第四导电单元3。
值得一提的是，第一桥接结构26是由一接线层透过微影制程来制作而成，而第二桥接结构36则是进一步由另一接线层透过微影制程来制作而成，换句话说，第一桥接结构26与第二桥接结构36虽皆属于接线层，但本实施例中，两者是藉由不同步骤且由不同的材料形成。举例来说，为了保持显示区A内的透光度, 第一桥接结构26采用与前述导电层相同的透明导电材料，如氧化铟锡（indium tin oxide, ITO )、氧化铟锌(indium zinc oxide, IZO)、氧化镉锡(cadmium tin oxide, CTO)、氧化铝锌(aluminum zinc oxide, AZO)、氧化铟锌锡(indium tin zinc oxide, ITZO)、氧化锌(zinc oxide)、氧化镉(cadmium oxide)、氧化铪(hafnium oxide, HfO)、氧化铟镓锌(indium gallium zinc oxide, InGaZnO)、氧化铟镓锌镁(indium gallium zinc magnesium oxide, InGaZnMgO)、氧化铟镓镁(indium gallium magnesium oxide, InGaMgO)或氧化铟镓铝(indium gallium aluminum oxide, InGaAlO)等。而位于周边区B的第二桥接结构36，为了让第二桥接结构36减少断裂机会并增加可靠度，第二桥接结构36较佳采用金属材料，如银、铝、金、铜等。但上述第一桥接结构26与第二桥接结构36的材料并不限于此，可依照实际需求而调整。
接着，触控面板1更包含一绝缘层41。本实施例之绝缘层41位于第一感应电极22与第二感应电极24之间，使得第一感应电极22及第二感应电极24之间彼此电性绝缘。此外，绝缘层41也位于第三感应电极32与第四感应电极34之间，使得第三感应电极32及第四感应电极34之间彼此电性绝缘。藉此，上述导电层、接线层及绝缘层41的迭层结构即可架构出本实施例的感应电极层。
本实施例的触控面板1更包括一引线结构40，对应位于周边区B，并且电性连接第一电极图案20与第二电极图案30。引线结构40更进一步电性连接触控面板1外部的一处理器(图未示)，用来传递处理器与第一电极图案20及第二电极图案30之间的信号。此外，本实施例的引线结构40可例如是在上述形成第二桥接结构36时，采用与第二桥接结构36相同的金属材料，并藉由同一道微影制程制作而成，不会增加整体的制程步骤。换句话说，本实施例的引线结构40同样属于所谓的接线层。
附带说明的是，本实施例的第二电极图案30是设计电性连接第一电极图案20，以作为第一电极图案20的延伸部。如此一来，第一电极图案20及第二电极图案30可以一体设计，藉以实现第一电极图案20及第二电极图案30的触控反应功能。其中第一电极图案20与第二电极图案30仅有桥接结构的材料不同，而本发明对第一桥接结构26与第二桥接结构36的形成先后顺序并不限定，可依照需求自由调整。
最后，本实施例之触控面板1更可进一步包含一钝化层(Passivation Layer) 80，用来设置在前述的感应电极层之上，并且完全覆盖感应电极层，以避免感应电极层受到化学性之侵蚀或物理性之损害而影响触控感应的功能。
此外，由于本实施例的图案化遮蔽层50的图案化区域51包含有镂空图案51a与51b，换言之，所述的镂空图案51a、51b的镂空部位是属于可供光线穿透的部位，因此本实施例之触控面板1可再包含一彩色膜层70，覆盖于钝化层80上，并对应图案化遮蔽层50来设置，使得第一图案化区域51中的镂空图案51a、51b得以进一步呈现出色彩效果。其中，彩色膜层70可例如是由彩色油墨、彩色光阻、导光油墨印刷或喷涂而成，或者藉由彩色贴膜黏贴而成，并且同一彩色膜层70并不仅限于单一颜色。如此，本实施例之触控面板1在外观上得以更富色彩效果而较为美观，并且只需简单藉由彩色膜层70的颜色变换，即可创造出产品的独特性。而值得注意的是，彩色膜层70不限于设置在钝化层80上，而可设置在触控面板1中的其他不同层，仅需对应图案化遮蔽层50来设置即可。
接下来，进一步说明本发明之触控面板1的制作过程。请基于图2所示的剖面图架构来参考图3所绘示的本发明第一较佳实施例之触控面板的制作方法的流程图。并且为了更明确地说明，可一并对应参考图4-7所绘示的本发明第一较佳实施例之触控面板的阶段架构俯视示意图。
首先，提供一上盖基板10（步骤S1）。接着，形成一图案化遮蔽层50于上盖基板10上（步骤S2）。如图4所示，本实施例是根据触控面板1所搭配的电子装置的显示器尺寸并透过图案化遮蔽层50的形成，让上盖基板10定义有一显示区A以及一周边区B，本实施例的周边区B是设计为围绕于显示区A。图案化遮蔽层50可例如是以印刷或喷涂制程所涂布而成，且本实施例之图案化遮蔽层50包含一图案化区域51。其中，图案化区域51包含至少一镂空图案51a与51b，本实施例之图案化区域51中的镂空图案51a、51b是作为虚拟按键用的符号。
在步骤S2之后，进行涂布一导电层（步骤S3），并进而进行图案化所述的导电层（步骤S4）。如图5所示，本实施例的导电层除了对应涂布位于上盖基板10的显示区A之外，更是进一步对应涂布于图案化遮蔽层50的图案化区域51。所述的导电层经图案化将形成有复数个沿第一轴向(本实施例中为X轴)平行排列的第一感应电极22位于显示区A内，以及复数个沿第一轴向(本实施例中为X轴)平行排列的第三感应电极32位于周边区B内；此外，所述的导电层更形成有复数个第二导电单元25位于显示区A内，沿着第二轴向(本实施例中为Y轴)间隔排列，以及复数个第四导电单元35位于周边区B内，沿着第二轴向(本实施例中为Y轴)间隔排列。
接着，涂布及图案化一绝缘层41（步骤S5）。如图6所示，本实施例的绝缘层41经图案化后形成于第一感应电极22的部分区域以及第三感应电极32的部分区域上，并且位于第二轴向上相邻的两个第二导电单元25之间及相邻的两个第四导电单元35之间。
在步骤S5之后，再分别形成复数个第一桥接结构26（步骤S6）以及复数个第二桥接结构36 (步骤S7)。如图7所示，第一桥接结构26是形成在显示区A中第一感应电极22上的绝缘层41，用来电性连接第二轴向上相邻的两个第二导电单元25，而第二桥接结构36是形成在周边区B中第三感应电极32上的绝缘层41，用来电性连接第二轴向上相邻的两个第四导电单元35。其中，由于本实施例的第一桥接结构26及第二桥接结构36是采用不同材料的设计，因此在不同的制程步骤来形成。在选用的材料方面，第一桥接结构26可由透明导电材料所制作，而第二桥接结构可由金属等导电性良好的材料制作。当然，本发明对第一桥接结构26及第二桥接结构36的形成顺序并不加以限定，也就是说，上述步骤S6以及步骤S7之顺序可以对调，也属于本发明所涵盖的范围内。
更具体来讲，第一桥接结构26得以透过绝缘层41而跨越导电层中的第一感应电极22，以分别沿第二轴向(Y轴)来电性连接相邻的两个第二导电单元25，进而整体架构出复数个沿第二轴向平行排列的第二感应电极24。同样地，第二桥接结构36得以透过绝缘层41而跨越导电层中的第三感应电极32，以分别沿第二轴向(Y轴)来电性连接相邻的两个第四导电单元35，进而整体架构出复数个沿第二轴向平行排列的第四感应电极34。藉此，上述导电层、绝缘层41及接线层所形成的感应电极层即可在上盖基板10的显示区A上形成一第一电极图案20，并且在图案化遮蔽层50上形成一第二电极图案30。
此外，本实施例在步骤S7形成第二桥接结构36时，更可同时形成一引线结构40于图案化遮蔽层50而对应位于上盖基板10的周边区B，并用来电性连接第一电极图案20及第二电极图案30。然而，本发明引线结构40也可与第一桥接结构26一同制作，或是第一桥接结构26、第二桥接结构36与引线结构40皆分别制作，都属于本发明所涵盖的范围内。
接下来，形成一钝化层80来覆盖于前述架构出的感应电极层（步骤S8）。其中，钝化层80可例如是采用无机材料，例如氮化硅(silicon nitride)、氧化硅(silicon oxide)与氮氧化硅(silicon oxynitride)，或者采用有机材料，例如丙烯酸类树脂(acrylic resin)，或其它适合之透明材料。
最后，形成一彩色膜层70于钝化层80上，并位于周边区B内来对应图案化遮蔽层50（步骤S9）。其中，彩色膜层70可例如是由彩色油墨、彩色光阻、导光油墨印刷或喷涂而成，并且所述的印刷或喷涂制程更可采取分道印刷的制程，以使彩色膜层70具备多样性的彩色效果。此外，所属技术领域具有通常知识者可以了解，彩色膜层70在本实施例之触控面板1的架构中，并不仅限能位于钝化层80上，只要是能对应位于图案化遮蔽层50，让从触控面板1正面观看时，图案化遮蔽层50的图案化区域51中的镂空图案51a、51能藉由彩色膜层70而具有彩色效果，皆是包含在本发明申请专利范围。
以下将针对本发明不同实施例进行说明，其中为凸显各实施例之间的不同处，相同的组件以相同之标号表示，其制作方法与材料与上述第一较佳实施例所述相同，并且不另外赘述。
第一较佳实施例的制程步骤中，感应电极层的制作，系先形成图案化的导电层，然后覆盖上绝缘层，接着才形成第一桥接结构及第二桥接结构来架构成完整的第一电极图案与第二电极图案，此制程顺序可定义为正制程。然而, 本发明除了以正制程形成感应电极层之外，更可以利用反制程形成感应电极层，也就是先形成桥接结构，且覆盖绝缘层后才形成导电层。以下将说明本发明第二较佳实施例的触控面板制作流程，请基于图9所示的剖面图架构来参考图8所绘示的本发明第二较佳实施例的制作流程图，并一并配合参考图10~13，其绘示的本发明第二较佳实施例之触控面板的阶段架构俯视示意图。
先说明的是，本实施例是根据触控面板1所搭配的电子装置的显示器尺寸，让上盖基板10定义有一显示区A以及一周边区B，对于显示区A及周边区B的定义如前述实施例所述，在此不再赘述，而本实施例的周边区B是例如设计为围绕于显示区A。
首先，提供一上盖基板10(步骤S10），接着，于显示区A内形成复数个第一桥接结构26(步骤S11)，接着形成一图案化遮蔽层50于上盖基板10上(步骤S12)。在此值得注意的是，本实施例中系先形成显示区A内的第一桥接结构26，才于周边区B形成图案化遮蔽层50，以减少形成第一桥接结构26时的高温破坏图案化遮蔽层50，但本发明不限于此，也可能依照实际需求，先形成图案化遮蔽层50后才形成各第一桥接结构26。此外，本实施例的图案化遮蔽层50可例如是不透明(如黑色光阻)材料，与上述本发明第一较佳实施例相同，采用印刷或喷涂制程所涂布形成。再者，本实施例的图案化遮蔽层50进一步包含一图案化区域51，并且图案化区域51中设计有至少一镂空图案51a及51b，本实施例是例如设计为返回键及首页键之按键符号的镂空图案。其中，图案化区域51中所设计的镂空图案之图形态样及数量并不限于此，实际更可依功能设计需求而包含其他如菜单键、开关键等按键符号。
再如图11所示，于周边区B内形成复数个第二桥接结构36(步骤S13)于图案化遮蔽层50上，其中第二桥接结构36较佳为金属材料，不但可增加触控面板2于周边区B信号的信号传输速度，更因为相较于透明导电材料(例如ITO等)，金属材料与图案化遮蔽层50(其材料通常为黑色光阻或是油墨)之间的附着力较佳，因此可有效减少后续形成于周边区B的电极图案的剥落或断裂情形。此外，在形成各第二桥接结构36的同时，本实施例中较佳并可一并形成复数条引线结构40，以节省制程步骤。当然，本发明不限于此，各第二桥接结构36与引线结构40也可能分别形成于不同的步骤，且形成的先后顺序可任意对调，也属于本发明所涵盖的范围内。至于第二桥接结构36与引线结构40的材料与制作方法与上述第一较佳实施例相同，在此不再赘述。
之后如图12所示，形成一绝缘层43覆盖于显示区A与周边区B内(步骤S14)，其中绝缘层43为一整片膜层，覆盖于上盖基板10、图案化遮蔽层50、各第一桥接结构26以及各第二桥接结构36，接着图案化绝缘层43，以形成复数个孔洞44，用以曝露出部分的第一桥接结构26与第二桥接结构36，尤其是各第一桥接结构26以及各第二桥接结构36的两端部分，以预留接触孔电性连接后续的电极图案。在本实施例中，绝缘层43形状虽与第一较佳实施例中的绝缘层41不同，但同样可达到隔绝后续形成的电极图案，避免不同方向的电极轴彼此之间互相干扰。当然，本实施例中的绝缘层43形状仅为一种实施态样，其可任意结合本发明前述或是后述的其他实施例中，本发明不以此为限。例如本实施例也可使用第一较佳实施例所述的绝缘层41覆盖于部分第一桥接结构26与第二桥接结构36上。相对的，第一较佳实施例中的绝缘层41也可取代为第二较佳实施例中的绝缘层43，皆属于本发明的变化型。
接着请参考图13，在绝缘层43完成后，涂布一导电层(步骤S15)于绝缘层43上以及各孔洞44内，并且图案化该导电层，形成第一电极图案20与第二电极图案30(步骤S16)，分别位于显示区A以及周边区B内，所述的导电层将形成有复数个沿第一轴向(本实施例中为X轴)平行排列的第一感应电极22位于显示区A内，以及复数个沿第一轴向(本实施例中为X轴)平行排列的第三感应电极32位于周边区B内；此外，所述的导电层更形成有复数个第二导电单元25位于显示区A内，沿着第二轴向(本实施例中为Y轴)间隔排列，以及复数个第四导电单元35位于周边区B内，沿着第二轴向(本实施例中为Y轴)间隔排列。本实施例中，第二导电单元25覆盖绝缘层43上的各孔洞44，使得相邻的两个第二导电单元25通过第一桥接结构26来电性连接，进而整体架构出复数个沿第二轴向平行排列的第二感应电极24。同样地，第四导电单元35覆盖绝缘层43上的各孔洞44，使得相邻的两个第四导电单元35通过第二桥接结构36来电性连接，进而整体架构出复数个沿第二轴向平行排列的第四感应电极34。
最后全面性覆盖上钝化层80(步骤S17)，以及于周边区B对应图案化区域51设置一彩色膜层70(步骤S18)后，即完成本实施例所述的触控面板2。如图9所示，本实施例中因采用反制程，也就是先形成桥接结构(包括第一桥接结构26与第二桥接结构36)后才形成电极图案(包括第一电极图案20与第二电极图案30)，因此第二桥接结构36将会直接接触图案化遮蔽层50，而两者之间的附着力较好，较不易使得位于周边区B内的第二电极图案30产生剥落或是断裂的情形。本实施例中，采用与第一较佳实施例不同制程顺序，而其余有相同标号的组件，其制作方法与材料选择与第一较佳实施例相同，在此不再赘述。
在本发明的另一较佳实施例中，可改变电极图案的分布，图14绘示本发明第三较佳实施例的触控面板俯视图，如图14所示，本实施例的架构及材料大致与图7所示的第一较佳实施例相同，不同之处在于位于周边区B内的第三电极图案60之设计。本实施例的第三电极图案60与第一电极图案20是独立分开的设计，也就是第三电极图案60与第一电极图案20之间并无直接的连接关系。
第三电极图案60包含有复数条沿第一轴向(本实施例中为X轴)平行排列的第五感应电极62与以及复数个第六导电单元65沿着第二轴向(本实施例中为Y轴)间隔排列。第二桥接结构36得以透过绝缘层41而跨越导电层中的第五感应电极62，以分别沿第二轴向(Y轴)来电性连接相邻的两个第六导电单元65，并且藉由引线结构40连接至外部的处理器上。此外，本实施例位于周边区B的第三电极图案60仅对应镂空图案51a及51b而设置，且不设置于周边区B的其他地方。另外，本实施例中所述的第三电极图案60，其仅为本发明的一种实施态样，而实际形状可依照需求而调整，当然，第三电极图案60也可以与上述第一较佳实施例或是第二较佳实施例相互组合，例如结合第二较佳实施例的反制程与第三较佳实施例的第三电极图案60形状，也属于本发明所涵盖的范围内。
综上所述，本发明之触控面板以及其制作方法是让触控面板的显示区及周边区内皆对应设计有电极数组，并且在周边区中进一步透过图案化遮蔽层来形成虚拟按键等符号。藉此，让同一触控面板表面上的显示区及周边区分别具有各自的触控反应功能。如此一来，本发明得以具有触控面板表面平整性佳、表面容易清洁等优点。此外，本发明的触控面板的显示区以及周边区内的电极图案分别以不同材料料来设计桥接结构，根据不同区域采用适合的材料，让显示区具有较佳的透光率，而周边区的桥接结构具有较高的可靠度。
以上所述仅为本发明之较佳实施例，凡依本发明申请专利范围所做之均等变化与修饰，皆应属本发明之涵盖范围。
