所述触控走线12连接所述触控单元11和所述触控开关14,并向所述触控单元11传输所述信号电压;
所述集成电路板13用以向所述触控单元11提供所述信号电压;
其中,通过触控开关的设置,使信号电压能够在所述触控单元阵列的两端输入,进而避免由于触控单元11之间电容不同对信号电压产生较大的影响,进而缓解触控单元11之间亮度显示不同的问题;但是由于每个触控单元11仅通过一根触控走线输出信号电压,当触控走线12位于触控单元11一侧,触控单元11内部的电阻过大,信号电压从触控单元11的一侧进入时,由于电阻的分压作用,必定导致与触控走线12对立一侧的区域所分的信号电压较弱,进而导致单个触控单元11内所对应像素区域的亮度不均,为了解决上述问题,本发明做以下设计:
所述触控单元11与至少两条所述触控走线12相连,至少两条所述触控走线12在所述触控单元11内均匀分布。
需要解释的是,所述至少两条触控走线12均与触控开关14相连,即意味的所述触控单元11能够通过至少两条触控走线12获取所需的信号电压,均匀分布的触控走线12会避免由于触控单元11内电阻较大对信号电压分布的影响,进而避免触控单元11所对应区域内像素亮度不均的问题。
进一步的,所述触控开关14包括薄膜晶体管,所述薄膜晶体管包括源极、漏极和栅极;
其中,所述栅极用以接收所述触控开关14的开关电压,所述源极用以接收所述信号电压,所述漏极与所述触控走线相连;当显示装置显示时,通过接收触控开关14的开关电压进而控制触控开关的开关,由于所述触控开关14通过源极和漏极将信号电压与触控走线相连,当触控开关14开启时,触控单元11便能够通过触控走线12接收到信号电压。
可以理解的是,在内嵌式触控面板中,触控单元阵列同时行使着公共电极相关功能,故信号电压接收情况能够进一步的影响显示装置的发光。
进一步的,所述触控开关14与所述触控走线12的个数一一对应。
优选的,所述第一触控单元111设置于异形区,所述第二触控单元112设置于所述普通区,所述第一触控单元111和所述第二触控单元112均通过所述触控走线12与所述触控开关14和集成电板板13相连,所述第一触控单元111与所述第二触控单元112的面积不同。
在一实施例中,所述第一触控单元111与两条所述触控走线12相连,所述触控走线12分别为位于所述第一触控单元111内的两端;
所述信号电压通过两条所述触控走线12进入所述第一触控单元。
优选的,所述第一触控单元111与m条所述触控走线12相连,m为大于或者等于2的整数,所述触控走线12在所述第一触控单元111内均匀分布;
所述信号电压通过m条所述触控走线12进入所述第一触控单元111。
优选的,所述触控走线12包括第一触控走线121和第二触控走线122,所述第一触控走线121与所述触控开关14和所述集成电路板13相连,所述第二触控走线122与所述触控开关13相连;
其中,与所述触控单元11相连的所述触控走线12包括一条所述第一触控走线121。
需要解释的是,在触控面板中,触控走单元中除触控走线12外还设置有闲置的伪触控走线,本发明可以在现有触控面板(如图2所示)中,选择远离触控走线12的一条伪触控走线进行延伸至触控开关14处并于触控开关14相连,进而形成新的触控走线12,为了进行区域,这里将原有的触控走线12记为第一触控走线121,通过伪触控走线修改而成的触控走线12记为第二触控走线122,进而简化了触控面板的制备工艺。
在现有触控面板中,由于不同类型触控面板的结构也不同,为此可进行进一步的限定,所述触控面板包括:
基板;
设置于所述基板上的第一金属层;
设置于所述第一金属层上的第一绝缘层;
设置于所述第一绝缘层上的第二金属层;
设置于所述第二金属层上的第二绝缘层;
设置于所述第二绝缘层上的第三金属层;
设置于所述第三金属层上的第三绝缘层;
设置于所述第三金属层上的触控层,所述触控单元11位于所述触控层;
其中,所述触控走线12位于所述第三金属层。
在另一实施例中,所述触控面板包括:
基板;
设置于所述基板上的第一金属层;
设置于所述第一金属层上的第一绝缘层;
设置于所述第一绝缘层上的第二金属层;
设置于所述第二金属层上的第二绝缘层;
设置于所述第二金属层上的触控层,所述触控单元位于所述触控层;
其中,所述触控走线位于所述第二金属层。
根据本发明的另一个发明,还提供了一种显示装置,包括本发明中所述的触控面板。
所述显示装置的工作原理与所述触控面板的工作原理相似,所述显示装置的工作原理具体请参考所述触控面板的工作原理,这里不再赘述。
本发明的优点是,提供了一种触控面板及显示装置,通过设置至少两条均匀分布的触控走线与触控单元相连,使得信号电压通过所述触控走线在所述触控单元内均匀传递,进而避免触控单元所对应像素区域内亮度显示不均匀的问题。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
