在完成上述触控电极层20的制备后,进一步沉积保护层30。其中,保护层30的制备可以采用现有技术的常规材料或者技术制备而成,此处不做进一步限定。
上述实施方式,通过将连接线层中的第一连接线设置于电极层下方,即从电极层的内部走线将其连接至焊接区,可以避开边缘走线对触控面板边框的影响,极大地减小边框宽度,甚至可以实现零边框设计。
本申请实施例中还提供了一种触控面板,包括触控基板触控电极层以及保护层。其中,触控电极层设置于触控基板上,触控电极层包括电极层、连接线层和绝缘层,电极层和连接线层位于绝缘层的两侧,电极层包括多个行列设置的第一电极及第二电极,连接线层包括设置于电极层上方或下方的第一连接线,每一行第一电极分别通过对应的第一连接线连接至焊接区,且每一第一连接线和除对应行之外其他所有行的第一电极绝缘。其具体描述此处不再赘述,详见上文描述。
综上所述,本领域技术人员容易理解,本申请提供一种触控面板及其制备方法,通过将连接线层中的第一连接线设置于电极层下方或下方,即从电极层的内部走线将其连接至焊接区,可以避开边缘走线对触控面板边框的影响,极大地减小边框宽度,甚至可以实现零边框设计。
以上所述仅为本申请的实施方式,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
