前述第一导电层 120、第一绝缘层 130、第二导电层 140与第二绝缘层 150 为触控面板结构 100的可视区域 AA。 另外, 触控面板结构 100还包括有遮光 层 160, 而遮光层 160例如为黑色矩阵 (Black Matrix, BM) 层。 遮光层 160 分别配置于基板 110上且位于可视区域 AA 的相对两侧, 亦即于可视区域 AA 的外围, 用以遮蔽触控面板结构 100内的电路接线的区域。
为清楚说明发明的特 ίΐ£请配合参考图 其为本发明的触控面板结构 100 的俯视图。 第一导电层 120具有多个第一电极 121, 且第一电极 121相互分离 且配置成平行于第一方向 X, 而第二导电层 140具有多个第二电极 141, 且第 二电极 141相互分离且配置成平行于第二方向 Y。 前述第一方向 X与第二方向 Υ之间可具有一夹角, 其例如为锐角、 直角或钝角, 然而图 2所绘示以直角作 为示例, 但并非用以限定本发明的范围。 并且, 在各第一电极 121与各第二电 极 141相互错位的交错处(如图 2所标示的区域 Α) 互不电性连接。 另外, 第 —电极 121与第二电极 141的形状例如为菱形但并非用以限定本发明的范围。
通过前述的配置关系, 可让触控面板内 (即可视区域 ΑΑ)的有图案区(即 配置第一电极或第二电极的区域)与无图案区(即未配置第一电极或第二电极 的区域) 的反射值相近, 使得人眼对有图案区与无图案区视为一致。 亦即, 当 使用者观看 (例如在太阳光底下使用) 具有此触控面板结构 100 的电子装置 时, 使用者不会看到菱形格的图案(即第一导电层 120的第一电极 121或第二 导电层 140的第二电极 141所呈现的形状)。
前述说明了触控面板结构的一实施范例, 但本发明不限于此。 以下将举另 一例来说明。
请参照图 3所示, 其为本发明的另一触控面板结构的剖面图。 触控面板结 构 300包括基板 310、 第一导电层 320、 第一绝缘层 330、 第二导电层 340与 第二绝缘层 350。 基板 310具有一设置面 311。 第一导电层 320配置于设置面 311, 第一导电层 310具有多个第一电极。第一绝缘层 330配置于设置面 311, 且与第一导电层 320之间具有一间隙 (i第二导电层 340配置于第一绝缘层 330 上, 第二导电层 340 具有多个第二电极, 且各第二电极与各第一电极相互错 位。第二绝缘层 350配置于第一导电层 320与第二导电层 340上并覆盖住各第 一电极与各第二电极, 且填满间隙 G, 以完成触控面板结构 300的制作。另外, 本实施例的第一电极与第二电极的配置关系可以参照图 2的说明, 故在此不在 赘述。
在本实施例中, 第二绝缘层 350可以喷涂的方式形成 而第一导电层 320、 第二导电层 340及第一绝缘层 330可以网印的方式形成。 其中, 第一绝缘层 330与第二导电层 340具有相同的图案, 亦即在形成第一绝缘层 330时, 并不 会遮蔽第一导电层 330的图案。
前述第一导电层 320、第一绝缘层 330、第二导电层 340与第二绝缘层 350 为触控面板结构 300的可视区域 AA ' 。 另外, 触控面板结构 300还包括有遮 光层 360, 而遮光层 360例如为黑色矩阵(Black Matrix, BM)层。 遮光层 360 分别配置于基板 310上且位于可视区域 AA' 的相对两恻亦即于可视区域 AA' 的外围, 用以遮蔽触控面板结构 300内的的电路接线的区域。
通过前述的配置, 可让触控面板内 (即可视区域 AA' ) 的有图案区 (即 配置第一导电层 320的第一电极或第二导电层 340的第二电极的区域)与无图 案区(即未配置第一导电层 320的第一电极或第二导电层 340的第二电极的区 域)的反射值相似, 使得人眼对有图案区与无图案区视为一致, 而使用者在太 阳光底下操作具有此触控面板结构 300的电子装置时, 不会看到菱形格的图案 (即第一导电层 320的第一电极或第二导电层 340的第二电极所呈现的形状)。
在本实施例中, 基板 310的材料可以是但不限定为玻璃; 第一导电层 320 与第二导电层 340的材料可以是但不限定为铟锡氧化物 第一绝缘层 330及第 二绝缘层 350的材料为光刻胶型绝缘材料, 且光刻胶型绝缘材料例如为醋酸酯 类。
由上述图 1的实施例的说明, 可以归纳出一种触控面板结构的制造方法。 请参照图 4所示, 其为本发明的触控面板结构的制造方法流程图。在歩骤 S410 中, 于一基板的一设置面上, 形成一第一导电层, 且第一导电层具有多个第一 电极。 在歩骤 S420中, 于基板的设置面上, 形成一第一绝缘层, 且第一绝缘 层覆盖住第一导电层的各第一电极。 在歩骤 S430中, 于第一绝缘层上, 形成 一第二导电层, 第二导电层具有多个第二电极, 且各第二电极与第一电极相互 错位。 在歩骤 S440中, 于第一绝缘层上, 形成一第二绝缘层, 且第二绝缘层 会覆盖住第二导电层的各第二电极。
另外, 由于第一绝缘层会覆盖于第一导电层上, 而使得第一导电层的电路 无法暴露出来。为了避免这样的情况产生, 因此在形成第一绝缘层的歩骤 S420 之前, 进行歩骤 S411 , 于第一导电层的电路配置的区域上, 形成一可剥胶。 如此一来, 在第一绝缘层形成后, 使用者可将可剥胶去除, 使得第一导电层的 电路暴露出来, 以进行后续电路的连接。
此外, 前述的制造方法更包括于基板上以及于第一导电层一测与相对第一 导电层的第一绝缘层的一侧(例如前述可视区域 AA的两侧), 分别形成一遮光 层。 此遮光层用以遮蔽触控面板结构内的电路接线的区域。
在本实施例中, 第一绝缘层与第二绝缘层可以喷涂的方式形成, 而第一导 电层与第二导电层可以网印的方式形成。 基板的材料可以是但不限定为玻璃; 第一导电层与第二导电层的材料可以是但不限定为铟锡氧化物 第一绝缘层与 第二绝缘层的材料可以是但不限定为光刻胶型绝缘材料, 且光刻胶型绝缘材料 例如为醋酸酯类。
由上述图 3的实施例, 可以归纳出一种触控面板结构的制造方法。 请参照 图 5所示, 其为本发明的另一触控面板结构的制造方法流程图。 在歩骤 S510 中, 于一基板的一设置面上, 形成一第一导电层, 且第一导电层具有多个第一 电极。 在歩骤 S520中, 于基板的设置面上, 形成一第一绝缘层, 且第一绝缘 层与第一导电层之间具有一间隙。 在歩骤 S530中, 于第一绝缘层上, 形成一 第二导电层, 且第二绝缘层具有多个第二电极, 而各第二电极与各第一电极相 互错位。在歩骤 S540中, 于第一导电层与第二导电层上, 形成一第二绝缘层, 第二绝缘层会覆盖住各第一电极与各第二电极且填满前述间隙。
另外, 前述的制造方法更包括于基板上以及于第一导电层一测与相对第一 导电层的第一绝缘层的一侧 (例如前述可视区域 AA ' 的两侧), 分别形成一遮 光层。 此遮光层用以遮蔽触控面板结构内的电路接线的区域。
在本实施例中, 第二绝缘层可以喷涂的方式形成, 而第一导电层、 第二导 电层及第一绝缘层可以网印的方式形成。 其中, 第一绝缘层与第二导电层具有 相同的图案, 亦即在形成第一绝缘层时, 并不会遮蔽第一导电层的图案。 基板 的材料可以是但不限定为玻璃 第一导电层与第二导电层的材料可以是但不限 定为铟锡氧化物 第一绝缘层与第二绝缘层的材料可以是但不限定为光刻胶型 绝缘材料, 且光刻胶型绝缘材料例如为醋酸酯类。
本发明的实施例所提供的触控面板结构及其制造方法, 其通过第一导电层 搭配第一绝缘层以及第二导电层搭配第二绝缘层, 使触控面板内的有图案区 (即配置第一导电层的第一电极或第二导电层的第二电极的区域)与无图案区 (即未配置第一导电层的第一电极或第二导电层的第二电极的区域)的反射值 相似 (几乎相近), 进而使人眼将有图案区与无图案区视为一致。 如此一来, 使用者观看(例如于太阳光下)具有此触控面板结构的电子装置时, 不会看到 菱形格的图案(即第一导电层的第一电极或第二导电层的第二电极所呈现的形 状)。
