具体实施方式
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元件之上下关系，在本领域之人皆应能理解其系指物件之相对位置而言，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。
请参阅图 1 与图 2 ，其中图 1 为本发明第一较佳实施例之触控面板的结构俯视图，图 2 为了图 1 中沿着剖面线 I-I' 的剖面图。如图所示，触控面板 1 至少包含有复数条第一电极轴 22 、复数条第二电极轴 24 以及复数条导线 26 ，其中该些第一电极轴 22 与对应的该些第二电极轴 24 位于共平面且彼此互相缠绕及电性绝缘，该些导线 26 则由同一方向分别连接对应的该些第一电极轴 22 与该些第二电极轴 24 。
触控面板 1 还可以包括一基板 10 ，基板 10 上区分有一显示区 12 以及一周边区 14 ，周边区 14 位于显示区 12 一侧，第一电极轴 22 及第二电极轴 24 位于该显示区 12 ，导线 26 位于该周边区 14 ，其中，第一电极轴 22 以及第二电极轴 24 位于同一平面上，互相缠绕且不彼此交叉重叠。本实施例中，各第一电极轴 22 与各第二电极轴 24 皆为连续结构，也就是说，各第一电极轴 22 与各第二电极轴 24 在 Y 轴上分别呈现一不间断的图案，每一条呈纵向排列的第一电极轴 22 与第二电极轴 24 仅分别需要一条导线 26 与外部的微处理器相连，因此可有效地降低导线的数量，进而节省制作成本。另外值得注意的是，由于本发明中导线 26 仅由单一方向连接第一电极轴 22 以及第二电极轴 24 ，因此仅需于显示区 12 周围预留单一侧的空间容纳导线 26 即可，同时也可以有效缩短导线的长度，降低导线的阻抗。
此外，显示区 12 上更定义有至少一感应区块 30 ，其范围以虚线表示。本实施例中，每一感应区块 30 内包含有单一条第一电极轴 22 以及单一条第二电极轴 24 。每一第一电极轴 22 包括至少一沿第一方向 ( 例如为 Y 轴方向 ) 成型的第一直杆部份 22a 、一沿第二方向 ( 例如为 X 轴方向 ) 成型横杆部份 22b 及一第一交握部份 22c ，其中横杆部分 22b 连接两个第一直杆部份 22a ，第一交握部份 22c 是从第一直杆部份 22a 沿着第二方向延伸形成。每一第二电极轴 24 包括至少一沿第一方向成型的第二直杆部份 24a 及一第二交握部份 24c ，其中第二交握部份 24c 是从第二直杆部份 24a 沿着第二方向延伸形成。第一直杆部份 22a 与对应的第二直杆部份 24a 平行排列，第一交握部份 22c 与对应的第二交握部份 24c 相互缠绕但彼此电性绝缘形成复数个缠绕区 25 ，因此，一感应区块 30 内排列有复数个缠绕区 25 ，且各缠绕区 25 彼此紧密排列。本实施例中，该第一交握部份 22c 与第二交握部份 24c 相互缠绕的型态是直角交握。
上述各导线 26 的一端由同一方向分别与第一电极轴 22 的第一直杆部份 22a 及第二电极轴 24 的第二直杆部份 24a 电性连接，而导线 26 的另一端则与一外部的微处理器 ( 图未示 ) 相连，以传输触控面板上所接收到的讯号至微处理器上。本发明的触控面板作动原理为，在每次进行触控前，外部的微处理器会先计算一次整体触控面板的电容，当作背景电容。当使用者以手指或其他接地导电物体接触本发明的触控面板时，将带走触控区域部分电荷而造成该处电容值的改变。此时微处理器将会扫描触控面板各处的电容值，并侦测到触控点的电容数值与背景电容值不同，进而判定受到触控的触控点位置。另外，由于本发明第一电极轴 22 与第二电极轴 24 彼此相互缠绕，因此在第一电极轴 22 与第二电极轴 24 之间将产生互电容，使用者碰触该点时，同样会使此处电容值产生改变，故本发明也可藉由比较各点的产生的互电容值变化，计算出使用者触控点。
本发明实施例提供的触控面板更包括一图案化屏蔽层 28 ，该图案化屏蔽层 28 位于该些感应区块 30 的外围，且各感应区块 30 之间藉由该图案化屏蔽层 28 隔开。图案化屏蔽层 28 一端接地，以减少各感应区块 30 之间电极的电荷干扰，提高触控面板的稳定度。其中值得注意的是，本实施例中，图案化屏蔽层 28 的作用为屏蔽各感应区块 30 之间的电性干扰，因此各感应区块 30 之间藉由图案化屏蔽层 28 隔开，但本发明并不限于此，也就是说，本发明中各感应区块 30 之间可无图案化屏蔽层 28 存在，仅在各感应区块 30 之间预留一足够屏蔽电荷干扰的空隙，更甚至整片基板上只有一个感应区块 30 ，而图案化屏蔽层 28 位于感应区块 30 的外围。
此外，可以于第一电极轴 22 、第二电极轴 24 、导线 26 及图案化屏蔽层 28 上覆盖一保护层 32 ，用以避免第一电极轴 22 、第二电极轴 24 、导线 26 及图案化屏蔽层 28 受到化学变化或是物理作用影响而损害。
上述的第一电极轴 22 、第二电极轴 24 及导线 26 可由相同材料所构成，包括各种透明导电材料例如氧化铟锡 (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) 、氧化锡 (tin oxide) 、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，此外，也可由细小分子材质如奈米碳管 (Carbon Nano Tube ,CNT) 、银奈米碳管或铜奈米碳管等，但不限于此。图案化屏蔽层 28 也可采用与第一电极轴 22 、第二电极轴 24 及导线 26 相同的材料制作。此外，导线 26 若采用与第一电极轴 22 以及第二电极轴 24 不同的材料制作，可选择导电性良好的金属如银（ Ag ）、铜 (Cu) 、金 (Au) 、铝 (Al) 、钼 (Mo) 、钨 (W) 、镍 (Ni) 、铁 (Fe) 、铂 (Pt) 、锡 (Sn) 、铅（ Pb ），或合金例如银铜、镉铜、铬铜、铍铜、锆铜、铝镁硅、铝镁、铝镁铁、铝锆等所构成，但不限于此。保护层 32 可包括无机材料 , 例如氮化硅 (silicon nitride) 、氧化硅 (silicon oxide) 与氮氧化硅 (silicon oxynitride) 、或是有机材料 , 例如 , 丙烯酸类树脂 (acrylic resin) 及其它适合之材料，但不以上述为限。基板 10 可包含有硬质基板，例如玻璃，或可绕曲基板，例如聚碳酸脂（ polycarbonate, PC ）、聚对苯二甲酸乙二脂 (polyethylene terephthalate, PET) 、聚甲基丙烯酸甲脂 (polymethylmesacrylate, PMMA) 、聚砜 (Polysulfone, PES) 或其他环烯共聚物（ cyclic olefin copolymer ）。
下文将针对本发明之触控装置的不同实施样态进行说明，且为简化说明，以下说明主要针对各实施例不同之处进行详述，而不再对相同之处作重复赘述。此外，本发明之各实施例中相同之元件系以相同之标号进行标示，以利于各实施例间互相对照。
图 3 为本发明第二较佳实施例之触控面板的结构上视图。如图 3 所示，触控面板 2 包含有一基板 10 ，基板 10 上规划有一显示区 12 以及一周边区 14 。显示区 12 内定义有复数个感应区块 30 。与本发明第一较佳实施例不同之处在于本实施例中，各感应区块 30 内包含有两条并列设置的第一电极轴 42 以及一条第二电极轴 44 ，每一第一电极轴 42 包括一沿第一方向 ( 例如为 Y 轴方向 ) 成型的第一直杆部份 42a 及至少一第一交握部份 42c ，其中第一交握部份 42c 是从第一直杆部份 42a 沿着一第二方向 ( 例如为 X 轴方向 ) 延伸形成。每一第二电极轴 44 包括一沿第一方向成型的第二直杆部份 44a 及至少一第二交握部份 44c ，其中第二交握部份 44c 是从第二直杆部份 44a 沿着第二方向延伸形成，第一直杆部份 42a 与第二直杆部份 44a 平行排列，第一交握部份 42c 与第二交握部份 44c 相互缠绕但彼此电性绝缘形成复数个缠绕区 45 。此外，各第一电极轴 42 的第一直杆部份 42a 与各第二电极轴 44 的第二直杆部份 44a 皆分别由导线 26 连接至外部的微处理上 ( 图未示 ) 。相较于本发明的第一较佳实施例，本实施例增加感应区块 30 内电极轴的数量，有助于提升触控面板的精准度。本实施例其余元件之材料与制作步骤皆与本发明第一较佳实施例相同，包括形成一图案化屏蔽层 28 位于基板 10 上，以及形成一保护层 ( 图 3 未绘示 ) 全面性覆盖各元件。
上述各实施例中，第一交握部份与第二交握部份相互缠绕的型态是直角交握，然而本发明却不以此为限制，图 4 为本发明第三较佳实施例之触控面板的结构上视图，如图 4 所示，触控面板 3 包含有一基板 10 ，基板 10 上规划有一显示区 12 以及一周边区 14 。显示区 12 内定义有复数个感应区块 30 ，感应区块 30 内包含有第一电极轴 52 以及第二电极轴 54 ，每一第一电极轴 52 包括至少一沿第一方向成型的第一直杆部份 52a 、一沿第二方向成型的横杆部份 52b 及至少一第一交握部份 52c ，其中该横杆部分 52b 连接两个第一直杆部份 52a ，该第一交握部份 52c 是从该第一直杆部份 52a 沿着第二方向延伸形成。 每一第二电极轴 54 包括一沿第一方向成型的第二直杆部份 54a 及一第二交握部份 54c ，其中第二交握部份 54c 是从该第二直杆部份 54a 沿着第二方向延伸形成，第一直杆部份 52a 与第二直杆部份 54a 平行排列，第一交握部份 52c 与第二交握部份 54c 相互缠绕但彼此电性绝缘形成复数个缠绕区 55 。与本发明第一较佳实施例不同之处在于第一电极轴 52 的第一交握部份 52c 与第二电极轴 54 的第二交握部份 54c 相互缠绕的型态是弧形交握，第二电极轴 54 的横杆部份 52b 为一弧形横杆部份。本实施例系提供第一交握部份与第二交握部份的另一种缠绕型态，但并不限于此，本发明的第一交握部份与第二交握部份相互缠绕的型态是直角交握或弧形交握或其他任意形式交握，只须满足第一电极轴与第二电极轴相互缠绕及电性绝缘却无彼此交叉重叠即可。
综上所述，本发明提供的触控面板，在基板的显示区内定义有至少一感应区块，各感应区块内包含有相同方向的第一电极轴与第二电极轴，第一电极轴与第二电极轴相互缠绕且无交叉堆迭，且第一电极轴与第二电极轴皆由相同方向的导线连接至外部的微处理器，因此在显示区外部，仅有一个方向须预留导线的位置，其余的方向预留空间可有效降低，增进触控面板显示区所占的面积。另外，本发明位于基板上的图案化屏蔽层可有效屏蔽各电极之间的相互干扰，提高触控面板的稳定度并增进效能。
上述实施例提供的触控面板可通过本发明提供的触控面板的制作方法来形成。图 5 为本发明较佳实施例之触控面板之制作方法的流程图，该制作方法包括步骤 S10 ：形成复数条第一电极轴； S12 ：形成复数条第二电极轴；以及 S14 ：形成复数条导线，其中，各该感应区块内形成的电极轴结构，在不同的实施例有不同的实施样态，例如各该感应区块内形成有单一条该第一电极轴与单一条该第二电极轴 ( 如图 1 与图 4 分别为的第一与第三实施例 ) ，或各该感应区块内形成有两条并列设置的该第一电极轴与一条该第二电极轴 ( 如图 3 所示的第二实施例 ) 。该些第一电极轴与对应的该些第二电极轴位于共平面且彼此互相缠绕及电性绝缘，该些导线则由同一方向分别连接对应的该些第一电极轴以及该些第二电极轴。其次，还包括步骤 S16: 形成一图案化屏蔽层于各感应区块的外围，且各感应区块之间藉由该图案化屏蔽层隔开。
于一较佳实施例中，步骤 S10 至步骤 S14 可合并为一个步骤 S1 ，在形成第一电极轴以及第二电极轴的同时，可形成复数条导线，即复数条第一电极轴、复数条第二电极轴以及复数条导线因采用同样材料而可在同一步骤 S1 中形成。另外，除了导线可以与第一电极轴以及第二电极轴同时制作外，图案化屏蔽层也可与上述各元件同时制作，即步骤 S10 至步骤 S16 可合并为一个步骤 S2 ，复数条第一电极轴、复数条第二电极轴、复数条导线以及图案化屏蔽层因采用同样材料而可在同一步骤 S2 中形成，藉以减少制程步骤，提高生产效率。当然，本发明不限于此，也就是说，第一电极轴、第二电极轴、导线以及图案化屏蔽层也可依照制程需求，由不同的步骤所完成，或是仅有部分上述元件于同一步骤形成，其余则由其他步骤形成。
此外，在完成第一电极轴、第二电极轴以及导线 ( 或者还包括形成图案化屏蔽层 ) 后，本实施例提供的触控面板之制作方法还可以包括步骤 S3 ：形成一保护层，覆盖于第一电极轴、第二电极轴以及导线上 ( 或者还包括覆盖于图案化屏蔽层上 ) ，用以避免该些元件受到化学变化或是物理作用影响而损害。
综上所述，本发明实施例提供的触控面板的制作方法，第一电极轴、第二电极轴、导线以及图案化屏蔽层可以在同一步骤中形成，可减少制程步骤，提高生产效率。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
