实施例一
如图 1所示为本发明实施例提供的内嵌式触摸显示面板各层的立体结构 示意图， 如图 2所示为本发明实施例提供的内嵌式触摸显示面板的俯视图， 如图中所示的内嵌式触摸显示面板包括相对设置的第一基板 1和第二基板 2, 所述第一基板 1上设置有驱动电极层 12, 所述驱动电极层 12包括多个驱动 电极 120,所述第二基板 2上设置有感应电极层 20,所述感应电极层 20包括 多个感应电极组， 每个所述感应电极组包括至少两个感应电极 200, 所述驱 动电极 120与所述感应电极 200交叉设置， 例如驱动电极 120为横向设置， 则感应电极 200为纵向设置， 相邻感应电极 200通过间隔设置的感应电极连 接线 201连接， 且所述感应电极连接线 201在所述第一基板 1上的投影与所 述驱动电极 120不重叠。
在一个示例中， 所述感应电极连接线 201与驱动电极 120的延伸方向平 行，即与感应电极 200的方向垂直，当然也可不平行只要感应电极连接线 201 在所述第一基板 1上的投影与驱动电极 120不重叠即可。
需要说明的是， 其中感应电极连接线 201间隔设置是指， 相邻感应电极 可以通过平行的多条感应电极连接线 201连接， 每个感应电极组中相邻的感 应电极 200通过感应电极连接线 201连接可以降低感应电极组的电阻， 感应 电极连接线 201的数量可根据需要设置， 在此不作限定。

所述第一基板 1和第二基板 2对盒后灌注液晶层 3即得到图 1所示的触 摸显示面板。
其中，所述金属电极层 10包括至少两个金属电极，每个金属电极的分布 与驱动电极方向平行， 且金属电极与驱动电极在第一基板 1上的投影可以重 叠， 也可以不重叠。
对于位于所述金属电极与所述感应电极连接线非对应位置处的第一金属 电极 100, 所述第一金属电极 100与所述驱动电极 120通过过孔 122连接， 所述过孔 122在所述第一基板 1上的投影位于所述驱动电极 120所在区域， 如图 3a所示。
进一步地， 对于所述金属电极与所述感应电极连接线对应位置处的第二 金属电极 101 , 所述第二金属电极 101通过周边连线与公共电极相连， 第二 金属电极 101没有通过过孔与驱动电极连接， 如图 3b所示。
对于第一金属电极 100,由于第一金属电极 100通过过孔与驱动电极 120 连接， 在显示面板分时驱动的触摸阶段， 第一金属电极 100传输驱动信号， 提供驱动灵敏度。 第二金属电极 101无论在触摸阶段还是显示阶段均与公共 电极连接， 只作为公共电极的一部分。
本发明实施例中所述的内嵌式触摸显示面板在触控阶段时， 所述金属电 极层中与所述驱动电极层中驱动电极连接的第一金属电极 100与所述驱动电 极层中的驱动电极同时作为驱动电极， 而金属电极层中的第二金属电极 101 只作为金属电极， 与公共电极连接； 所述具有上述内嵌式触摸显示面板的触 摸屏处于显示阶段时， 所述金属电极层中未与所述驱动电极层中的驱动电极 连接的第二金属电极 101作为金属电极， 所述第一金属电极 100与所述驱动 电极层中的驱动电极同时作为驱动电极； 如此， 能避免驱动电极层中的驱动 电极与感应电极层中的感应电极形成正对面积， 且能避免驱动电极层中的驱 动电极与感应电极层中的感应电极之间的电容大幅增加， 进而能为提高触摸 屏的性能奠定基础。 而且， 由于金属电极层中的第二金属电极 101无论在显 示阶段、 还是触控阶段均作为金属电极， 因此， 能进一步减小驱动电极层中 性能奠定基础。
本发明实施例的内嵌式触摸显示面板， 将感应电极层中相邻的感应电极 相连， 以使所述相邻的感应电极相连， 如此， 能减小感应电极组的电阻。
总之， 本发明实施例提供的内嵌式触摸显示面板， 既减小了感应电极的 负载， 又没有增加额外节点电容， 而且， 本发明实施例提供的内嵌式触摸显 示面板能通过软件模拟找出最优化配置方案，将各项负载控制在最优范围内， 进而能提供触摸屏的性能。
进一步的， 由于本发明实施例中的内嵌式触摸显示面板主要针对的是内 嵌式触摸显示面板， 驱动电极采用的是共用公共电极， 每条公共电极作为一 条驱动电极使用， 因此所述第一基板 1可以为阵列基板， 所述第二基板 2可 以为对盒基板。
实施例三
本发明实施例还提供一种显示装置， 包括以上所述的任一内嵌式触摸显 示面板。 本发明实施例中的显示面板主要应用于高级超维场转换 ( ADvanced Super Dimension Switch, ADS )模式的触摸显示面板， 但不限于此。 本发明 实施例中 ADS模式的触摸显示面板驱动电极共用的是位于阵列基板上的采 用铟锡金属氧化物材料 ( Indium Tin Oxides, ITO )的透明公共电极， 由于铟 锡金属氧化物相对电阻率较大， 因此会采用将铟锡金属氧化物通过过孔与电 阻率较小的金属相连， 以降低公共电极的电阻。
实施例四
本发明实施例还提供一种内嵌式触摸显示面板的制造方法， 包括： 在第一基板上通过构图工艺依次形成金属电极层、 第一绝缘层、 驱动电 极层、 第二绝缘层， 所述驱动电极层包括至少多个驱动电极， 所述金属电极 层包括至少两个金属电极； 在第二基板上通过构图工艺形成感应电极层， 所述感应电极层包括多个 感应电极组， 每个所述感应电极组包括至少两个感应电极， 所述每个感应电 极组相邻的感应电极通过间隔设置的感应电极连接线连接， 所述感应电极连 接线与所述驱动电极延伸方向平行， 且所述感应电极连接线在所述第一基板 上的投影与所述驱动电极不重叠。
进一步地， 对于所述金属电极与所述感应电极连接线非对应位置处， 所 述金属电极与所述驱动电极通过过孔连接， 所述过孔在所述第一基板上的投 影位于所述驱动电极区域。
进一步地， 对于所述金属电极与所述感应电极连接线对应位置处， 所述 金属电极通过周边连线与公共电极相连。
进一步地,金属电极可以采用与阵列基板中的栅线或数据线相同的材料， 但不限于此。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
