具体实施方式
为使本公开的原理、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
图1为本公开实施例提供的一种触控面板的结构示意图，如图1所示，该触控面板包括：衬底基板01，以及沿远离衬底基板01的方向依次排布的第一导电层02、绝缘层03和第二导电层04。
其中，第一导电层02包括：第一触控电极021、第二触控电极022、第三触控电极023、第四触控电极024、第一连接电极025和第二连接电极026。第一连接电极025呈环状，且包围第二连接电极026。第一触控电极021和第二触控电极022位于第一连接电极025在第一方向x上的两侧，第三触控电极023和第四触控电极024位于第一连接电极025在第二方向y上的两侧。第一方向x与第二方向y的夹角大于零，图1中以第一方向x与第二方向y的夹角为90度为例，当然该夹角也可以为大于零的其他度数，如80度等。
绝缘层03包括：两个第一绝缘垫031、两个第二绝缘垫032、两个第三绝 缘垫033和两个第四绝缘垫034。其中，两个第一绝缘垫031的一端均搭接在第一触控电极021上，另一端均搭接在第一连接电极025上。两个第二绝缘垫032的一端均搭接在第二触控电极022上，另一端均搭接在第一连接电极025上。两个第三绝缘垫033的一端均搭接在第三触控电极023上，另一端均跨过第一连接电极025并搭接在第二连接电极026上。两个第四绝缘垫034的一端均搭接在第四触控电极024上，另一端均跨过第一连接电极025并搭接在第二连接电极026上。
第二导电层04包括：两个第一导电桥041、两个第二导电桥042、两个第三导电桥043和两个第四导电桥044。其中，两个第一导电桥041与两个第一绝缘垫031一一对应，每个第一导电桥041位于其对应的第一绝缘垫031上，且两端分别与第一触控电极021和第一连接电极025电连接。两个第二导电桥042与两个第二绝缘垫032一一对应，每个第二导电桥042位于其对应的第二绝缘垫032上，且两端分别与第二触控电极022和第一连接电极025电连接。两个第三导电桥043与两个第三绝缘垫033一一对应，每个第三导电桥042位于其对应的第三绝缘垫033上，且两端分别与第三触控电极023和第二连接电极026电连接。两个第四导电桥044与两个第四绝缘垫034一一对应，每个第四导电桥044位于其对应的第四绝缘垫034上，且两端分别与第四触控电极024和第二连接电极026电连接。
从图1可以看出，本公开实施例中，第一触控电极021、第一连接电极025和第二触控电极022依次电连接形成沿第一方向x延伸的电极；第三触控电极023、第二连接电极026和第四触控电极024依次电连接形成沿第二方向y延伸的电极；并且，该沿第一方向x延伸的电极与沿第二方向y延伸的电极相互交叉。该触控面板可以为互容式触控面板。
综上所述，本公开实施例提供了一种全新的触控面板，该触控面板与相关技术中触控面板的结构不同，因此，丰富了触控面板的结构。
可选地，请继续参考图1，第一连接电极025在衬底基板01上的正投影呈八边环形；第二连接电极026在衬底基板01上的正投影呈八边形，且八边环形中的八个内边B1一一平行于八边形的八条边B2。图1中仅标出了一条内边和八边形的一条边。
可选地，第一连接电极025在第一方向x上的环宽w，大于第一连接电极025在第二方向y上的环宽c；第一连接电极025在第一方向x上的最大长度L1， 大于第一连接电极025在第二方向y上的最大长度L2。第二连接电极026在第一方向x上的最大长度L3，小于第二连接电极026在第二方向y上的最大长度L4。
可选地，上述八边形具有第一对称轴D1和第二对称轴D2，第一对称轴D1平行于第一方向x，第二对称轴D2平行于第二方向y。两个第一导电桥041关于第一对称轴D1对称，两个第二导电桥042关于第一对称轴D1对称，两个第一导电桥041和两个第二导电桥042关于第二对称轴D2对称。两个第三导电桥043关于第二对称轴D2对称，两个第四导电桥044关于第二对称轴D2对称，两个第三导电桥043和两个第四导电桥044关于第一对称轴D1对称。这样一来，触控面板中的导电桥对称分布，导电桥的分布较均匀，从而能够降低导电桥的可视性。
可选地，两个第一导电桥041和两个第二导电桥042均呈条形，且均与各自连接的八边环形的一条外边B3垂直，两个第一导电桥041和两个第二导电桥042垂直的四条外边B3不同(图1中仅标出了一条外边B3)。可选地，第一导电桥041的长度大于第一绝缘垫031在该第一导电桥041长度方向上的长度，第一绝缘垫031在该长度方向上的长度大于第一导电桥041与第一连接电极025的间隙的宽度；类似地，第二导电桥042的长度大于第二绝缘垫032在该第二导电桥042长度方向上的长度，第二绝缘垫032在该长度方向上的长度大于第二导电桥042与第一连接电极025的间隙的宽度。
两个第三导电桥043和两个第四导电桥044均呈折线形，且均包括两个导电条051；导电条051的长度为e，两个导电条051之间的夹角为θ，
Figure PCTCN2019098680-appb-000002
其中，第一连接电极025与第二连接电极026的间距为d，第一连接电极025与第三触控电极023的间距为d，第一连接电极025与第四触控电极024的间距为d，第一连接电极025的最小环宽为c，第三绝缘垫033在其对应的第三方向上的长度为f，第四绝缘垫034在其对应的第四方向上的长度为f；第三绝缘垫033对应的第三方向垂直于第三绝缘垫033搭接的第三触控电极023朝向第二连接电极025的方向，第四绝缘垫034对应的第四方向垂直于第四绝缘垫034搭接的第四触控电极024朝向第二连接电极 025的方向。
可选地，请继续参考图1，两个第三导电桥043的弯折角(如图1中的弯折角m和弯折角n)的开口方向相反。两个第四导电桥043的弯折角(如图1中弯折角p和弯折角θ)的开口方向相反。这样一来，触控面板中的导电桥并不是都沿同一方向规则排布，从而能够降低导电桥的可视性。
需要说明的是，图1中以第三导电桥043和第四导电桥044均呈折线形为例，可选地，该第三导电桥043和第四导电桥044也可以呈条形。
示例地，图2为本公开实施例提供的另一种触控面板的结构示意图，如图2所示，两个第一导电桥041、两个第二导电桥042、两个第三导电桥043和两个第四导电桥044均呈条形，且均与各自连接的八边环形(第一连接电极025)的一条外边B3垂直。并且，两个第一导电桥041、两个第二导电桥042、两个第三导电桥043和两个第四导电桥044垂直的八条外边B3不同。两个第三导电桥043和两个第四导电桥044的长度均大于2d+c；其中，第一连接电极与第二连接电极的间距为d，第一连接电极与第三触控电极的间距为d，第一连接电极与第四触控电极的间距为d，第一连接电极的最小环宽为c。
可选地，第一导电桥041的长度大于第一绝缘垫031在第一导电桥长度方向上的长度，第一绝缘垫031在该长度方向上的长度大于第一导电桥041与第一连接电极025的间隙的宽度；类似地，第二导电桥042的长度大于第二绝缘垫032在第二导电桥长度方向上的长度，第二绝缘垫032在该长度方向上的长度大于第二导电桥042与第一连接电极025的间隙的宽度。
另外，无论两个第一导电桥、两个第二导电桥、两个第三导电桥和两个第四导电桥的形状如何(如图1或图2中的形状)，如图3所示，这些导电桥中每个导电桥两端的距离L1小于220微米，且每个导电桥的宽度L2小于20微米。需要说明的是，图3中仅以呈条形的导电桥为例。
本公开实施例提供的触控面板中，导电桥两端的距离小于220微米，且导电桥的宽度小于20微米。而相关技术中导电桥两端的距离大于220微米，导电桥的宽度大于20微米。由于导电桥两端的距离越小，导电桥的可视性越低，导电桥的宽度越小，导电桥的可视性越低。因此，本公开实施例中，将至少部分导电桥两端的距离和导电桥的宽度中的至少一个减小，能够降低导电桥的可视性，从而减少导电桥影。
可选地，每个导电桥两端的距离小于110微米或100微米等。在导电桥两 端的距离小于110微米或小于100微米时，导电桥两端的距离进一步的被减小，从而进一步地降低了导电桥的可视性。可选地，每个导电桥的宽度小于15微米或10微米等。在导电桥的宽度L2小于10微米或15微米时，导电桥的宽度进一步的被减小，从而进一步地降低了导电桥的可视性。
可选地，两个第一导电桥041、两个第二导电桥042、两个第三导电桥043和两个第四导电桥044的材料均包括金属。需要说明的是，本公开实施例中的导电桥03可以遮光或透光，当导电桥03遮光时，导电桥03的材质可以为金属或者其他遮光导电材质(如石墨烯等)，当导电桥03透光时，导电桥03的材质可以为氧化铟锡或其他透光导电材质(如氧化铟锌等)。另外，当导电桥03的材质为金属时，由于金属的阻抗较小，因此导电桥03的导电效果较好。
请继续参考图1或图2，无论导电桥的形状如何，第一导电层02还包括：位于第一触控电极021、第二触控电极022、第三触控电极023和第四触控电极024中每相邻的两个电极之间的辅助电极027。并且，辅助电极027、第一触控电极021、第二触控电极022、第三触控电极023和第四触控电极024中任意两个电极之间存在间隙J。
可选地，第一触控电极021、第二触控电极022、第三触控电极023和第四触控电极024中每相邻的两个电极之间具有两个辅助电极027；并且，辅助电极027呈梯形，且两个辅助电极027中每个辅助电极027的下底所在侧朝向另一辅助电极027。
可选地，辅助电极027的所呈梯形的高度可以小于30微米，可以看出，该梯形的高度较小，因此，可以降低辅助电极027的可视性。
另外，图1和图2所示的触控面板可以包括阵列排布的多个触控电极，这些触控电极包括上述第一触控电极、第二触控电极、第三触控电极和第四触控电极。该触控面板还可以包括与多行触控电极一一对应的多条第一连接线071，与多列触控电极一一对应的多条第二连接线072。每行触控电极中的一个触控电极与该行触控电极对应的第一连接线071电连接，每列触控电极中的一个触控电极与该列触控电极对应的第二连接线072电连接。
通过第一连接线和第二连接线，能够向连接线连接的触控电极施加电信号，以及采集触控电极上的电信号，从而进行触控位置的检测。示例地，在进行触控位置检测时，可以依次通过多条第二连接线向多列触控电极施加驱动电信号；在每向一列触控电极施加驱动电信号后，需要通过多条第一连接线采集多行触 控电极上的感应电信号；当在向第p列触控电极施加驱动电信号后，从第q行触控电极上采集到的感应电信号并不是预设电信号，而从其他行触控电极上采集到的感应电信号均为预设电信号时，可以确定第p列触控电极与第q行触控电极的交叉位置为触控位置。其中，p≥1，q≥1。
综上所述，本公开实施例提供了一种全新的触控面板，该触控面板与相关技术中触控面板的结构不同，因此，丰富了触控面板的结构。
并且，本公开实施例提供的触控面板中，导电桥两端的距离小于220微米，导电桥的宽度小于20微米。而相关技术中导电桥两端的距离大于220微米，导电桥的宽度大于20微米。由于导电桥两端的距离越小，导电桥的可视性越低，导电桥的宽度越小，导电桥的可视性越低。因此，本公开实施例中，将导电桥两端的距离和导电桥的宽度减小，能够降低导电桥的可视性，从而减少导电桥影。
本公开实施例还提供了一种触控显示面板，该触控显示面板可以包括显示面板，以及本公开实施例提供的任一种触控面板(如图1或图2所示的触控面板)。示例地，触控面板可以位于显示面板的出光侧；或者，触控面板中的衬底基板为显示面板中的封装层。
进一步地，上述触控显示面板可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有触控显示功能的产品或部件。
