随着大尺寸显示应用的发展，人机互动的需求也越来越多，而触控应用成为人机互动中的一个重要媒介。
触控面板根据感应技术不同可分为电阻式、电容式、光学式、音波式四种，目前主流的触控技术为电容式。触控面板根据结构不同可划分为：嵌入式触控显示面板和外挂式触控显示面板。其中嵌入式触控显示面板是将触控面板功能嵌入到液晶显示面板内，使得液晶显示面板同时具备显示和感知触控输入的功能，相比于外挂式触控显示面板，具有成本较低，厚度较薄等优点，受到各大面板厂家青睐。其中电容式触控技术（Capacitive Touch，简称CTP），具备响应速度快，外观抢眼等优势，成为大尺寸触控领域的重要发展方向，而异方性导电胶膜(Anisotropic Conductive Film，简称ACF）是现有技术的触控面板中必不可少的部分。

实施例一
本申请涉及一种触控面板，包括衬底和设置于所述衬底表面的触控电极层。电容式触控面板在液晶、彩色滤光片之外，触控电路需有额外的至少一个玻璃衬底，在所述玻璃衬底两侧具有条状图形的铟锡氧化物（Indium tin oxide，ITO），上下层的ITO呈垂直配置，在玻璃衬底的一侧形成有金属导线。
本申请所提供的实施例利用喷印工艺，将导电材料喷印到衬底的一侧，及利用激光刻印方法，将喷印的导电材料刻除不需要的部分。
进一步的，本申请实施例中信号传输区的电路可配置于不同层，而达到多点触控的功能。所述衬底的材料可为偏光片、聚对苯二甲酸乙二醇酯膜层（Polyethylene terephthalate，PET）或者聚酰亚胺膜层(PolyimideFilm，PI)等柔性基材。
此外，衬底一侧可预先形成有铟锡氧化物，利用激光刻印方法，将ITO刻除不需要的部分，以来形成信号传输区的电路。
在本实施例中，衬底还包括彩色滤光片，甚至于在彩色滤光片的外侧预先有平坦化树脂，及与下方液晶相接的ITO背电极。
实施例二
如图1所示，触控面板包括衬底和设置于所述衬底表面的触控电极层101、转换器102，以及连接在转换器102一侧的控制器103。
所述转换器102设于所述触控电极层101的顶面，连接触控电极层102和控制器103，所述转换器102接头与触控触控电极层101突出于所述衬底的边缘相互匹配。
图2为本申请实施例的分解图，触控电极层201包括触控信号传输区204，所述触控信号传输区204突出于衬底的边缘形成凸块2041，所述转换器202接头包括第一连接端2021与第二连接端2022，所述凸块2041与所述转换器202的第一连接端2021卡接，且与触控电极层201内部走线电连接，所述转换器202的第二连接端2022连接有控制器203。
所述转换器202为可拆卸装置，所述转换器202底部可设置有粘接层，所述粘接层设置于所述触控电极层201底部和所述控制器203底部之间。

进一步的，本申请中的触控电极层201的材质可以为一种聚合物材料，其具有高透光性且具有良好的热稳定性和化学稳定性，当触控电极层201和控制器203间产生热时，不会因此而发生巨大的形貌变化，且可以防止连接处发生化学腐蚀。

进一步的，所述信号输入/输出端子30411和转换器的第一连接端都置于所述触控电极层的同一表面。
本申请实施例中，针对现有技术的触控面板存在操作复杂，良率低，修复工作性能低，触控层易受到高温对材料的影响提供一种新型触控面板。
有益效果为：本申请通过将触控电极层的信号线端子引入触控信号传输区，通过转换器将触控信号传输区与控制器连接以实现触控信号的传输，连接方式便捷可靠，同时替代了使用绑定制程将触控电极与控制器连接，避免触控电极在绑定制程中的高温影响。
综上所述，虽然本申请已将优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
