Description

触控面板及其制作方法 技术领域
本发明是有关于触控技术领域，且特别是有关于一种触控面板及其制作方法。
背景技术
传统的触控技术中，触控面板主要包括一盖板及一触控感测结构，该触控感测结构与该盖板相贴合或者该触控感测结构直接设置于该盖板之下表面。其中该盖板之下表面包含一用于显示的可视区和一围绕于该可视区的非可视区，其中非可视区内设有一层不透光的遮蔽层于该盖板的下表面上，在一些产品中，非可视区内会设置简单的功能按键模组，为此，遮蔽层相应区域会蚀刻出相应的按键图案。
为了使该按键图案呈现彩色效果，遮蔽层的下表面上会直接设置ㄧ与按键图案相对应的装饰层，一般情况下，为了让按键图案显示出的彩色效果更加清晰明显，装饰层需由多层颜色涂层及效果层堆迭而成，这样一来，装饰层的存在将使得盖板之下表面在可视区与非可视区之间的表面断差明显，从而导致盖板与触控感测结构相贴合时或者触控感测结构形成于盖板之下表面时，在前述的断差区域中出现严重的贴合气泡或者触控感测结构断裂等问题。
发明内容
为解决上述问题，本发明提供一种触控面板，该触控面板界定有一可视区及一紧邻该可视区的非可视区，该触控面板包括：一盖板；一第一装饰层，位于该非可视区；以及一触控感测结构与一遮蔽层，该触控感测结构与该遮蔽层在该非可视区是整合性地成型设置于该盖板与该第一装饰层之间，该触控感测结构在该可视区中是设置在该盖板下方，其中在该遮蔽层上设计有一图案，位于该非可视区的该触控感测结构与该第一装饰层会对应至该遮蔽层的该图案。
于一变化实施例中，其中该触控感测结构在该非可视区是位于该盖板与该遮蔽层之间。
于一变化实施例中，其中该遮蔽层在该非可视区是位于该盖板与该触控感测结构之间。
于一变化实施例中，更包括一基板及一胶层，在该非可视区中，该基板位于该第一装饰层下方，该胶层位于该触控感测结构与遮蔽层之间。
于一变化实施例中，更包括一基板及一胶层，在该非可视区中，该基板位于该触控感测结构与该第一装饰层之间，该胶层位于该触控感测结构与该遮蔽层之间。
于一变化实施例中，更包含有一第二装饰层位于该遮蔽层与该触控感测结构之间，并对应该图案设置。
于一变化实施例中，更包括一基板及一胶层，在该非可视区中，该基板位于该第一装饰层下方，该胶层位于该第二装饰层与该触控感测结构之间。
于一变化实施例中，更包括一基板及一胶层，该基板位于该触控感测结构与该第一装饰层之间，该胶层位于该第二装饰层与该触控感测结构之间。
于一变化实施例中，其中该第二装饰层的厚度小于或等于20微米。
于一变化实施例中，其中该第二装饰层可为单层或多层结构。
于一变化实施例中，其中该第一装饰层可为单层或多层结构。
于一变化实施例中，其中该第一装饰层或第二装饰层包含一透明层。
于一变化实施例中，其中该第一装饰层与该第二装饰层的颜色相同。
于一变化实施例中，其中该第一装饰层与该第二装饰层的颜色不同。
于一变化实施例中，其中该图案系以一蚀刻方式形成的一镂空图案。
本发明还提供一种触控面板之制作方法，其中该触控面板界定有一可视区及一紧邻该可视区的非可视区，该触控面板之制作方法包含：在该非可视区形成一遮蔽层，其中在该遮蔽层上形成一图案；在该可视区与该非可视区形成一触控感测结构，其中在该非可视区的该触控感测结构会对应至该图案，在该可视区的该触控感测结构是形成在一盖板的下方；以及在形成该触控感测结构之后，在该非可视区形成一对应该图案的装饰层。
本发明在非可视区中将不设置装饰层于遮蔽层以及触控感测结构之间，或者即便要设置，也是设置厚度较薄的装饰层于遮蔽层以及触控感测结构之间，如此在制作触控感测结构前，可有效降低盖板之下表面于触控面板之可视区以及非可视区之间的高度差，从而有效降低先前技术中提及的技术问题。

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。
本发明提供一种触控面板界定有一可视区及一紧邻该可视区的非可视区，其中该可视区为一透明区域，在电子产品中，例如触控显示装置，位于触控面板下方的显示介面对应于该可视区，使得显示介面不会被触控面板阻挡；该非可视区为一不透光区域，用于遮蔽触控面板之触控感测结构中的一些非透明元件，例如周边引线等。该非可视区紧挨该可视区，一般设于触控面板之周边区域，视产品的需求，该非可视区可仅设于触控面板的一个边缘处，亦可设置于两个或三个边缘处，而较为常见的为非可视区围绕于可视区的四周。该触控面板包括：盖板；第一装饰层，位于该非可视区；以及触控感测结构与遮蔽层，该触控感测结构与该遮蔽层在该非可视区是整合性地成型设置于该盖板与该第一装饰层之间，该触控感测结构在该可视区中是设置在该盖板下方，其中在该遮蔽层上设计有图案，位于该非可视区的该触控感测结构与该第一装饰层会对应至该遮蔽层的该图案。以下通过具体的实施例来说明本发明之技术。
图1绘示本发明第一较佳实施例的触控面板结构上视图，图2绘示本发明第一较佳实施例的局部结构示意图，图3绘示本发明图1中沿剖面线I-I’所得的剖面结构示意图。如图1至图3所示，触控面板10界定有可视区101及围绕可视区101的非可视区102，并包含盖板11、遮蔽层12、触控感测结构13以及第一装饰层14。其中，盖板11可为一强化玻璃板或一塑化膜，其上表面可供用户触碰，下表面可设置如下所述其他组成触控面板的元件。
遮蔽层12在非可视区102可位于盖板11与触控感测结构13之间，在本实施例中，遮蔽层12在非可视区102中可位于盖板11的下表面，其中遮蔽层12的材料为不透光材料，例如有色油墨，其作用为遮蔽位于非可视区内的其他电路元件，以保证产品的外观。遮蔽层12上设有图案121，图案121系为通过蚀刻的方式形成于遮蔽层12上的镂空图案，其可以是位于非可视区内的触控功能按键图形、产品的品牌标识或其他装饰图案，本实施例中，图案121为位于非可视区内的触控功能按键图形。
触控感测结构13在非可视区102可位于遮蔽层12的下表面且对应至图案121，触控感测结构13在可视区101则可设置在盖板101下方，例如可直接设置在盖板11的下表面，但在其他实施例中，触控感测结构13与盖板11之间在可视区101范围中亦可设置其他辅助性元件层，在此并不加以限定。
第一装饰层14是位于非可视区102且在非可视区102内可位于触控感测结构13的下表面并对应图案121，用以使得图案121的镂空部分显示出相应的色彩效果。
本实施例中，如图1所示，触控感测结构13包括有复数条沿着一第一方向 (本实施例中为X轴) 平行排列的第一轴向电极131，以及复数条沿着一第二方向 (本实施例中为Y轴) 平行排列的第二轴向电极132。其中，第二轴向电极132与第一轴向电极131相互绝缘且第二轴向电极132包括复数个导电单元1321以及复数条电性连接两相邻导电单元1321的连接线1322，其中第一轴向电极131与导电单元1321位于同一平面，第一轴向电极131与连接线1322间有一绝缘层133存在，该绝缘层133可防止彼此互相电性干扰。触控感测结构13另包含复数条位于非可视区102的导电线路134，各导电线路134一端分别与第一轴向电极131以及第二轴向电极132电性连接，另一端与外部的一处理器(图未示)相连，该处理器用以接收并分析从触控面板所接收到的触摸信号。本实施例中，触控感测结构13为单层触控电极结构，即第一轴向电极131与导电单元1322位于同一层级平面，这一结构可使触控感测结构13的厚度降低，但值得注意的是，触控感测结构13的结构并不限于此，其可以是双层或多层的触控电极结构，即两个轴向的电极通过一整面的绝缘层分隔到不同的平面。
本实施例中，触控感测结构13所包含的第一轴向电极131与第二轴向电极132主要由透明导电材料所组成,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)、氧化铟镓铝(indium gallium aluminum oxide, InGaAlO)、奈米碳管(Carbon Nano Tube ,CNT)、银奈米碳管或铜奈米碳管等，,或是其他透明导电材质与金属或非金属的合成物，不过以上材料更可依实际需求而有所不同,在此并非为本发明所限制。
本实施例中，图案121为一镂空的图形，故从触控面板10下方的发光源（图未示）发出的光线部份会被遮蔽层12阻挡，但可直接通过图案121以凸显出图案121的镂空部分。第一装饰层14的设置是为了使图案121的镂空部分显示出相应的色彩效果，其可为ㄧ透明层、一由任意具有任何色彩的透光材质所形成的颜色层或是一由多层材质所组合的复合层。位于触控面板下方的发光源所发出的光线依序通过第一装饰层14、触控感测结构13以及图案121后，在使用者介面呈现ㄧ彩色图案，值得注意的是，第一装饰层14可以为单层结构或是ㄧ多层结构，以组合成各种不同的颜色。由于本发明将第一装饰层14设置于触控感测结构13的下表面，如此ㄧ来在触控感测结构13形成前，盖板11在非可视区102的下表面仅有遮蔽层12存在，使得可视区101以及非可视区102之交界处产生的高度差较小，触控感测结构13可形成于ㄧ相对平缓的表面上，可减少触控感测结构13形成时产生瑕疵的可能。
值得注意的是，当触控面板10的按键模组需具有触控功能时，触控感测结构13将会由可视区101延伸至位于非可视区102的图案121的所在区域，以提供触控面板10位于非可视区102内的图形按键具备触控功能，但本发明并不限于此，于其他实施例中，触控感测结构13包含一第一感测部及一独立于第一感测部之第二感测部，其中第一感测部位于可视区101，第二感测部位于非可视区102并对应于图案121，使得图案121处具备触控感测功能。触控感测结构13设置在图案121所在区域内，且系位于第一装饰层14与遮蔽层12之间，由于触控感测结构13的电极主要由透明导电材质所构成，因此不会遮蔽下方发光源的光线。此外，若是图案121仅作产品的品牌标识或其他装饰图案，也可省略将触控感测结构13延伸至图案121所在区域之材料。
值得注意的是，本实施例中，遮蔽层12系位于盖板11与触控感测结构13之间，而熟悉本领域之技术人员可理解的是，遮蔽层12的位置并不限于此，于本发明之其他实施例中，遮蔽层12可位于触控感测结构13下方，换言之，在触控面板之可视区与非可视区触控感测结构13都可直接制作于盖板11之下表面，即触控感测结构13位于盖板11与遮蔽层12之间，于该实施例中，应具体说明的是，触控感测结构13也并非完全位于盖板11与遮蔽层12之间，换言之，触控感测结构13之复数导电线路134位于遮蔽层12之下表面，并透过其他电连接方式与第一轴向电极131与第二轴向电极132相连接。例如透过一跨接结构或于遮蔽层12中的相应位置穿孔连接。亦即遮蔽层12与触控感测结构13可为整合性的组合元件，因此设置在盖板11与装饰层14之间的相对位置可非为固定，可以是先遮蔽层12再触控感测结构13的堆迭关系(如图3所示)，或是先触控感测结构13再遮蔽层12的堆迭关系，如上文字所述。
下文将针对本发明之半导体元件及其制作方法的不同实施态样进行说明，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。
上述本发明第一较佳实施例之触控面板10在可视区101是将触控感测结构13直接制作于盖板11之下表面，不需要提供额外的基板承载触控感测结构13，也就是触控玻璃一体化(Touch on lens, TOL)之结构，而本发明却不限于此，也就是说本发明可另外提供一基板承载触控感测结构13。图4绘示本发明第二较佳实施例的结构剖面图，如图4所示，触控面板20界定有可视区101及围绕可视区101的非可视区102，触控面板20包含前述第一实施例的盖板11、遮蔽层12、触控感测结构13及第一装饰层14。与本发明第一较佳实施例的不同之处在于，本实施例的触控面板20更包括了一基板21，其中触控感测结构13及第一装饰层14是设置在基板21的上表面，而非形成于盖板11上，即以图4由上而下视之，基板21在非可视区102中是位于第一装饰层14下方，在可视区101则是位于触控感测结构13下方。本实施例中，触控面板20更包括一贴合盖板11与基板21的胶层22，该胶层22在非可视区102是设置在触控感测结构13与遮蔽层12之间，在可视区则是设置在触控感测结构13与盖板11之间，其中，胶层22可为整面的结构，亦可为边框结构。本实施例中，其余各部件之特征、材料特性以及制作方法与上述本发明第一较佳实施例相同，故在此不再赘述。
图5绘示本发明第三较佳实施例的结构剖面图，如图5所示，本实施例与本发明第二较佳实施例不同之处在于，触控面板30之基板31在非可视区102是位于第一装饰层14与触控感测结构13之间，也就是在非可视区102中，触控感测结构13与第一装饰层14是分别设置在基板31的上表面与下表面，而在可视区101中，基板31是设置在触控感测结构13的下方。此外，本实施例中同样包含有一贴合盖板11与基板31的胶层32，胶层32在非可视区102中是设置在触控感测结构13与遮蔽层12之间，胶层32在可视区101中是设置在触控感测结构13与盖板11之间，其中，胶层32可为整面的结构，亦可为边框结构。本实施例中，其余各部件之特征、材料特性以及制作方法与上述第二较佳实施例相似，故在此并不再赘述。
为使得触控面板的图案121在不同状态下能显示不同种色彩效果，如在电子产品处于工作状态时，图案显示出的颜色为蓝色，而当电子产品处于非工作状态时，如待机或关机，图案显示出的颜色为银色，本发明更可包含有一设置于遮蔽层以及触控感测结构之间的第二装饰层，以提供电子产品处于非工作状态时图案显示的色彩。图6绘示本发明第四较佳实施例的结构剖面图，如图6所示，触控面板40界定有可视区101及围绕可视区101的非可视区102，触控面板40包含前述第一实施例的盖板11、遮蔽层12、触控感测结构13及第一装饰层14。与本发明第一较佳实施例不同之处在于，本实施例在遮蔽层12与触控感测结构13之间更设置有一对应图案121的第二装饰层41，第二装饰层41与第一装饰层14的颜色可以相同，也可以不同。第二装饰层41与第一装饰层14的颜色相同，可加强图案121的显示效果；第二装饰层与第一装饰层颜色不相同，可藉由第一装饰层14与第二装饰层41的重迭，图案121可以有不同种颜色组合，举例来说，当第一装饰层14为红色，而第二装饰层41为蓝色，且位于触控面板下表面之发光源并未发出光线时，从使用者介面看来，由于外部光线射入第二装饰层41并反射，图案将呈现蓝色，而当发光源发出光线，第一装饰层所发出的红光即会与蓝色调和，而呈现紫色的按键图案，换言之，图案在不同状态下能显示不同种色彩效果，如在电子产品处于工作状态时，图案显示出的颜色为紫色，而当电子产品处处于非工作状态时，如待机或关机，图案显示出的颜色为蓝色，值得注意的是，本发明的第一装饰层14与第二装饰层41皆可分别为单层结构或是多层结构，本发明并不以此为限。但本发明中，第二装饰层41的厚度应不超过20微米，以保证第二装饰层41的厚度不影响后续形成触控感测结构13时出现的气泡或断裂等技术问题。该第二装饰层41可为ㄧ透明层、一由任意具有任何色彩的透光材质所形成的颜色层或是一由多层材质所组合的复合层。在结构上，第二装饰层41可以为单层结构或多层结构。本实施例中其余各部件之特征、材料特性以及制作方法与上述第一较佳实施例相似，故在此并不再赘述。
图7绘示本发明第五较佳实施例的结构剖面图，如图7所示，本发明第五较佳实施例与本发明第四较佳实施例的不同之处在于，本实施例之触控面板50更包括了一基板51，其中第二装饰层41、触控感测结构13及第一装饰层14在非可视区102中可从上而下依序堆迭于基板51的上表面，而非形成在盖板11的下表面，即在非可视区102中，基板51可位于第一装饰层14下方，在可视区101中，基板51可位于触控感测结构13下方。本实施例中，触控面板50更包括一贴合盖板11与基板51的胶层52，胶层52在非可视区102中是位于触控感测结构13与第二装饰层41之间，在可视区101中是位于触控感测结构13与盖板11之间，其中，胶层52可为整面的结构，亦可为边框结构。本实施例中，其余各部件之特征、材料特性以及制作方法与上述本发明第四较佳实施例相同，故在此不再赘述。
图8绘示本发明第六较佳实施例的结构剖面图，如图8所示，本实施例与本发明第五较佳实施例不同之处在于，本实施例之触控面板60之基板61在非可视区102是位于第一装饰层14与触控感测结构13之间，也就是在非可视区102中，触控感测结构13与第一装饰层14是分别设置在基板61的上表面与下表面，而在可视区101中，基板61是设置在触控感测结构13的下方。此外，本实施例中同样包含有一贴合盖板11与基板61的胶层62，胶层62在非可视区102中是设置在第二装饰层41与触控感测结构13之间，胶层62在可视区101中是设置在触控感测结构13与盖板11之间，其中，胶层62可为整面的结构，亦可为边框结构。本实施例中，其余各部件之特征、材料特性以及制作方法与上述第五较佳实施例相似，故在此并不再赘述。
此外，本发明中第一装饰层与第二装饰层的位置可依照实际需求而有所变动，例如上述第四～第六较佳实施例中，第二装饰层41可选择性设置于其他位置，例如盖板11与遮蔽层12之间、触控感测结构13与胶层之间等，本发明只需满足至少ㄧ装饰层设置于触控感测结构13下方并对应于图案121，皆属于本发明所涵盖的范围内。
本发明还提供一种触控面板之制作方法。图9绘示本发明之触控面板之制作方法的流程图，包含以下步骤：
步骤S1，在非可视区形成一遮蔽层，其中在遮蔽层上形成一图案。
步骤S2，在可视区与非可视区形成一触控感测结构，其中在非可视区的触控感测结构会对应至在遮蔽层上的图案，在可视区的触控感测结构是形成在一盖板的下方。
步骤S3，在形成触控感测结构之后，在非可视区形成一对应该图案的第一装饰层，即在非可视区中，遮蔽层与触控感测结构可设置在盖板与第一装饰层之间。形成第一装饰层的方式一般为涂布印刷的方式，由于第一装饰层需达到一定厚度才能使得遮蔽层上的图案显现出的色彩效果明显，故第一装饰层可通过多次涂布印刷步骤而形成。
其中，遮蔽层与触控感测结构可为整合性的组合元件，因此设置在盖板与装饰层之间的相对位置可非为固定，可以是先遮蔽层再触控感测结构的堆迭顺序(如图3所示)，或是先触控感测结构再遮蔽层的堆迭顺序。
另外，本发明之触控面板的制造方法更包括基板、胶层及第二装饰层的形成步骤，该些元件与步骤S1~S3所揭示的元件在形成顺序上可参上述第一至第六实施例的堆迭关系而依序完成，以图8所示的第六实施例为例，可分别在盖板11与基板61上各自形成对应的元件，例如在基板61的非可视区102，可先形成触控感测结构13在基板61的上表面，再一并形成第一装饰层14于基板61的下表面及形成第二装饰层41于触控感测结构13的上表面，或是让第一装饰层14与第二装饰层41先后形成，而在盖板11的非可视区102中，则形成具镂空图案的遮蔽层于盖板11的下表面，再涂布或贴附胶层62在盖板11或基板61上，最后进行盖板11与基板61的贴合程序，其他实施例的形成顺序则可依此推知而不再赘述。
综上所述，本发明提供一种触控面板及其制造方法，其特征在于一第一装饰层设置于触控感测结构之下方，在触控感测结构形成时，可有效降低因盖板之下表面不平整所导致后续形成的触控感测结构产生瑕疵的机率。此外本发明的结构可整合于不同的触控面板堆迭结构。
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。
