具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明提供一种触控显示设备，所述触控显示设备能够进行画面显示以及触控操作。所述触控显示设备可以为手机，操作显示屏等任意的触控显示设备。所述触控显示设备包括设备主体以及与所述设备主体连接的触控显示面板。
请参阅图1，本发明提供一种触控显示面板100，所述触控显示面板100包括显示面板10及触控层。所述触控层层叠于所述显示面板10上或者嵌入于所述显示面板10内。所述显示面板10包括衬底基板11及层叠于所述衬底基 板11上的阳极层12、发光层13及阴极层14。所述发光层13包括多个阵列设置的发光单元131，每个所述发光单元131设置有发光材料，使得每个所述发光单元131发出不同颜色的光，所述触控显示面板100能够进行不同的画面显示。本实施例中相邻的两个所述发光单元131之间间隔设置。
所述触控层包括多条平行间隔设置的第一电极线，以及多条平行间隔设置的第二电极线，所述第一电极线与所述第二电极线交叉设置。可以理解的是，在其他实施例中，多条第一电极线或者多条第二电极线也可以不平行，本实施例中平行设置的电极线能够得到更好的触控效果，并且方便生产。本申请中，所述第一电极线沿第一方向延伸，所述第二电极线沿第二方向延伸，所述第一方向与所述第二方向交叉。任意相邻的两条第一电极线与相邻的两条第二电极线围成一个像素区域，每个所述像素区域与一个发光单元131或由多个所述发光单元131组成的一组发光单元相对应，即每个发光单元131或者每组发光单元均位于第一电极线以及第二电极线交叉形成的像素区域中。本申请的所述第一电极线及第二电极线对应于相邻的两个所述发光单元之间，从而避免所述第一电极线及所述第二电极线对所述显示单元发光的遮挡，从而保证所述触控显示面板100的显示效果。
进一步的，部分所述第一电极线和/或部分所述第二电极线上设有多个间隔设置的断口，从而使得部分所述像素区域具有缺口，形成非封闭的像素区域。并且，本发明中，具有断口的每条所述电极线(包括第一电极线与第二电极线)的断口将每条所述电极线分为多段子电极线。本发明中，每段所述子电极线均与连续的(即不具有断口)的电极线连接，从而保证电信号能够通过连续的电极线传输至所述子电极线上。
本发明通过在所述触控层的部分所述第一电极线和/或部分所述第二电极线上设有多个间隔设置的断口，从而降低触控层的背景电容值Cm，从而增加感应变化电容值ΔCm与背景电容值Cm的比值，使得所述触控显示面板100具有良好的触控效果。
进一步的，本申请中通过在部分所述第一电极线和/或部分第二电极线上设置断口，使得至少部分所述像素区域为非封闭的区域。相对于现有技术中的每个所述像素区域均为封闭的区域的情况来说，由于本申请的每个像素区域为 非封闭的区域，即所述第一电极线与第二电极线不需要全部封闭所述像素区域，使得所述第一电极线与第二电极线的面积能够减小，进而使得所述第一电极线及所述第二电极线与所述显示面板10的阴极之间的电容负载减小，即使得所述背景电容值Cm减小，并能够减少所述第一电极线与第二电极线之间的节点数，从而进一步的减少所述背景电容值Cm，进而的增大所述感应变化电容值ΔCm与背景电容值Cm的比值，使得所述触控显示面板100具有更好的触控效果。
以几个具体实施例为例对本申请进行说明。
请再次参阅图1，本实施例中，所述触控层20层叠于所述显示面板10上。具体的，所述触控层20层叠于所述显示面板10的阴极层14上。且所述阴极层14与所述触控层20之间还设有封装层15，用于对所述显示面板10进行保护，防止水氧等进入所述显示面板10内而影响所述显示面板10的发光。所述阳极层12包括多个阵列并间隔设置的阳极121，每个所述阳极121与一个所述发光单元131相对应。所述阴极层14为完整的平面结构。所述衬底基板11与所述阳极121层12之间还设有控制层16，所述控制层16包括多个阵列设置的薄膜晶体管，每个所述薄膜晶体管与一个所述阳极121电连接，以控制每个所述阳极121与所述阴极之间的电势差，从而控制位于每个阳极121与阴极层14之间的每个发光单元131的发光亮度，从而实现不同的画面显示。
可以理解的是，在其他实施例中，触控层20也可以设置在封装层15与基板10之间。具体的，所述阴极层14和/或阳极层12图案化设置，即所述阴极层14包括多个阵列并间隔设置的阴极和/或阳极层12包括多个阵列并间隔设置的阳极，且相邻的阴极或者相邻的阳极间隔有空隙。所述触控层20的电极线(包括所述第一电极线21和/或第二电极线22)布设于所述相邻的阴极和/或相邻的阳极121的间隙内。
请参阅图2及图3，本实施例的所述触控层20包括间隔排布的多条第一电极链20a及间隔排布的多条第二电极链20b。所述第二电极链20b与所述第一电极链20a交叉绝缘设置。本实施例中，所述第二电极链20b与所述第一电极链20a垂直。
每条第一电极链20a包括多个间隔的第一电极201，相邻的两个所述第一 电极201之间通过连接段202电连接。本实施例中，所述第一电极201为菱形，所述连接段202连接于相邻的两个第一电极201的一个角。可以理解的是，根据实际需要所述第一电极201也可以为方形、三角形等其它形状。所述第一电极201及所述连接段202位于同一层。
每条所述第二电极链20b包括多个间隔的第二电极203，所述第一电极201与所述第二电极203位于同一层，并与所述第一电极201通过同一制程得到。相邻的两个所述第二电极203通过导电桥204电连接，所述导电桥204跨设于所述连接段202上并通过绝缘层25与所述连接段202绝缘。换句话说，所述导电桥204与所述连接段202位于不同层，所述导电桥204的两端分别通过过孔连接相邻的两个第二电极203。请参阅图4，在本发明其它实施例中，所述连接段202也可以相对于所述导电桥204更接近于所述显示面板10。
本实施例中，所述第二电极203为与所述第一电极201形状大小相同的菱形，任两个相邻的第一电极201与任两个相邻的第二电极203交叉设置形成一个大的菱形结构。相邻的第一电极201与第二电极203之间通过绝缘层205间隔并绝缘，所述第一电极201与所述第二电极203及其之间的绝缘层205会形成电容。当触控所述触控层20的任意位置时，触控位置的电容会发生改变，通过检测电容的改变从而获取实施的触控位置，从而实现触控功能。
并且，请同时参阅图2及图5，本实施例中，所述第一电极201、所述连接段202、所述第二电极203及所述导电桥204均为多条间隔设置的所述第一电极线21及间隔设置的所述第二电极线22交叉形成的网格状结构。所述网格状结构的网格为本实施例的所述像素区域23。本实施例中，位于同一层内形成各个结构的通过同一制程得到，从而尽量较少所述触控显示面板100的制程。换句话说，本实施例的所述第一电极201、连接段202、第二电极203通过同一制程得到。需要强调的是，图5中的第一电极线21及第二电极线22均为直线，第一电极线21与第二电极线22交叉形成的网格为菱形。但需强调的是，本申请附图仅为示意图，实际上，本申请的所述第一电极线21与所述第二电极线22可以为波浪型线或者其它的非直线，从而形成具有不同形状的所述网格。
进一步的，本实施例中，多条所述第一电极线21均为连续线，多条所述 第二电极线22包括交替设置的连续线221及断口线222。其中，所述连续线为连续无断口24的电极线，所述断口线为具有多个间隔设置的断口24的电极线。本实施例中，相邻的两个所述断口24之间的距离小于所述像素区域23与所述第二电极线22平行的边的长度，以使每个所述像素区域23的边上设有一个断口24而得到非封闭的所述像素区域23。可以理解的是，所述第一电极线21也可以包括交替设置的连续线及断口线，从而进一步的减小所述触控层20与显示面板10的阴极层14之间的电容负载，以进一步减小所述背景电容值Cm，进一步的提高感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。
请参阅图6，进一步的，本实施例中，形成所述导电桥204的第一电极线21及第二电极线22与形成所述连接段202的第一电极线21与第二电极线22在垂直于所述触控层20的方向上错开。所述导电桥204的第一电极线21及第二电极线22与所述连接段202的第一电极线21及第二电极线22不重合，从而减小所述导电桥204与所述连接段202之间的电容负载，进一步减小所述背景电容值Cm，提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。
进一步的，相邻的两个所述第二电极203通过一条或者多条间隔设置的导电桥204电连接。本实施例中，相邻的两个所述第二电极203通过多条间隔设置的导电桥204电连接，相较于现有技术中通过一条导电桥204连接相邻的两个第二电极203的方式，由于设置所述导电桥204的区域是有限的，因此本申请中的间隔设置的多条所述导电桥204的总面积小于现有技术的导电桥204的面积，从而减小所述导电桥204与所述连接段202及所述第一电极201及第二电极203之间的电容负载，从而能够减小所述背景电容值Cm，提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。
进一步的，请参阅图7，本实施例中，所述第一电极201及所述第二电极203的边缘均呈齿状，且相互嵌合。具体的，每个所述第一电极201及所述第二电极203的边缘均设有多个凸起2011，相邻的两个凸起2011之间形成有凹口2012。每个所述第一电极201的凸起2011与同其相邻的所述第二电极203 的凹口2012相对，且每个所述第一电极201的凹口2012与所述第二电极203的凸起2011相对，从而增加所述第一电极201与同其相邻的第二电极203的之间的有效互容面积，增加感应变化电容值ΔCm，进而提高所述ΔCm/Cm的值，提升所述触控显示面板100的触控效果。其中，所述凸起2011及凹口2012可以为任意形状。例如，所述凸起2011及凹口2012可以为方形、三角形或者半圆形等形状。本实施例中，所述凸起2011及凹口2012为方形。
本实施例中，通过在所述第一电极线21和/或第二电极线22上设置所述断口24，从而减小所述触控层20与所述显示面板10的阴极层14之间的电容负载，从而减小所述背景电容值Cm。进一步的，通过将所述导电桥204的第一电极线21及第二电极线22与所述连接段202的第一电极线21及第二电极线22在垂直于所述触控层20的方向上错开，从而减小所述导电桥204与所述连接段202之间的电容负载，进一步的降低所述背景电容值Cm，进而提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。进一步的，通过将所述第一电极201及所述第二电极203的边缘设置为具有凸起2011及凹口2012的结构，从而增加所述第一电极201与所述第二电极203之间的有效互容面积，从而增加感应变化电容值ΔCm，进而进一步的提高所述ΔCm/Cm的值，提升所述触控显示面板100的触控效果。
本发明的其它实施例中，所述触控层包括第一电极层和与第一电极层绝缘设置的第二电极层。所述第一电极层包括数条所述第一电极线和/或第二电极线，所述第二电极层包括数条所述第二电极线和/或第一电极线。所述第一电极层的所述第一电极线和/或第二电极线与所述第二电极层的所述第二电极和/或第二电极线交叉围成所述像素区域。即所述像素区域23为所述第一电极层的电极线与所述第二电极层的电极线在所述显示面板10上的投影共同围成的。
具体的，请参阅图8及图9，本发明另一实施例中，所述触控显示面板100包括所述显示面板10及触控层30。其中，所述显示面板10的结构与图1所述实施例的所述显示面板10的结构相同，包括基板11及封装层15。所述触控层30包括第一电极层31、第二电极层33以及绝缘介质层32。所述绝缘介质层32设于所述第一电极层31与所述第二电极层33之间，用于实现所述第 一电极层31与所述第二电极层33的绝缘。本实施例中，所述绝缘介质层32将所述第一电极层31与所述第二电极层33完全分开，所述第一电极层31与所述第二电极层33位于不同层，并分置于所述绝缘介质层32两侧。本实施例中，将所述触控层20设于所述显示面板10上的封装层15上，且所述第一电极层31相对于所述第二电极层33更接近所述显示面板10。可以理解的是，在本发明的其它实施例中，所述第二电极层33能够相对于所述第一电极层31更接近所述显示面板10。
可以理解的是，在其他实施例中，所述触控层30也可以设置在封装层15内。还可以理解的是，在其他实施例中，所述触控层30仅包括所述第一电极层31及第二电极层33，第一电极层31设置在封装层15上远离基板11的一侧，第二电极层33设置在封装层15与基板11之间，从而实现所述第一电极层31与第二电极层32的绝缘。
所述第一电极层31包括多条所述第一电极线311。所述第二电极层33包括多条所述第一电极线331及多条所述第二电极线332。所述第二电极层33上的所述第一电极线331与所述第一电极层31的第一电极线311错开。每一个所述像素区域23为所述第一电极层31的第一电极线311、所述第二电极层33的第一电极线331以及第二电极层33的第二电极线332围成。每条所述第一电极线331上均设有多个间隔设置的所述断口34。
本实施例中，由于围成所述像素区域23的第一电极线及第二电极线均分置于不同的两层，因此，所述像素区域23必定为非封闭结构。相较于现有的像素区域23封闭的触控层来说，本申请的所述触控显示面板100的背景电容值Cm减小，从而使得所述感应变化电容值ΔCm与背景电容值Cm的比值提高，提升所述触控显示面板100的触控效果。具体的，本实施例中，由于所述第一电极层31仅包括第一电极线311，相较于第一电极层31均包括第一电极线及第二电极线的情况，本实施例的所述第一电极层31与所述第二电极层33之间的电容负载减小，以减小背景电容值Cm；并且，由于所述第二电极层33的第一电极线331上设有断口34，从而能够减少所述第一电极层31与所述第二电极层33的电极线之间的节点数，从而进一步的减小背景电容值Cm，进而提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显 示面板100的触控效果。
可以理解的是，请参阅图10，在本发明的其它实施例中，在图8所述实施例的基础上，所述第一电极层31还包括第二电极线312，所述第一电极层31的所述第二电极线22与所述第二电极层33的第二电极线22错开设置。所述像素区域23为所述第一电极层31的第一电极线311及所述第一电极层31的第二电极线312，以及所述第二电极层33的第一电极线331及所述第二电极层33的第二电极线332围成。并且，所述第二电极线22上也可以设置多个间隔设置的断口34，使得所述第二电极层33与所述显示面板10的阴极层14之间的电容负载减小。
本发明的另一实施例中，所述触控层20的结构与图7及图8所述的触控层20的结构基本相同，区别在于：本实施例的所述第一电极层31的电极线(包括第一电极线311及第二电极线312)与所述第二电极层33的电极线(包括第一电极线331及第二电极线312)位于同一层，所述绝缘介质层32包括多个阵列设置的区块，每个所述区块位于所述第一电极层31的电极线与所述第二电极层33的电极线交叉的位置，从而保证所述第一电极层31的电极线与所述第二电极层33的电极线绝缘。

所述第二电极层43包括多条平行间隔设置的所述第一电极线431及多条平行间隔设置的第二电极线432。所述第二电极层43的第一电极线431与所述第一电极层41的第一电极线411的延伸方向相同，在垂直于所述触控层20的方向上，所述第二电极层43的所述第一电极线431与所述第一电极层41 的第一电极线411错开；所述第二电极层43的所述第二电极线432与所述第一电极层41的第二电极线412错开，从而减少所述第一电极层41与所述第二电极层43之间的电容负载，以减小所述背景电容值Cm。并且，本实施例中，所述第一电极层41的所述第一电极线411与所述第二电极线412围成所述像素区域23，所述第二电极层43的第一电极线431与第二电极线432围成所述像素区域23；在垂直于所述触控层40的方向上，所述第一电极层41的所述第一电极线411与所述第二电极线412围成的所述像素区域23与所述第二电极层42的第一电极线431与第二电极线432围成的所述像素区域23部分重合，且所述第一电极层41的第二电极层42的像素区域重合的部分覆盖一个或者多个所述发光单元。换句话说，所述第一电极层41的第一电极线411以及第二电极层43的第一电极线431位于相同的两个相邻的两个发光单元之间，所述第一电极层41的第二电极线412与第二电极层43的第二电极线432位于两个相邻的两个发光单元之间，相较于相邻的两个发光单元之间仅有第一电极层41的第一电极线411或者第二电极线432来说，本申请的感应变化电容值ΔCm增加，从而进一步的提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。
进一步的，本实施例中，所述第一电极层41的所述第一电极线411包括交替设置的连续线4111及断口线4112，所述第二电极线412均为断口线。所述第二电极层43的所述第一电极线431包括交替设置的连续线4312及断口线4311，所述第二电极线432均为断口线。其中，所述连续线为连续无断口的电极线，所述断口线为具有多个间隔设置的所述断口44的电极线。所述第一电极线(第一电极线411或第一电极线431)的相邻两个断口44之间的距离为所述像素区域23与所述第一电极线(第一电极线411或第一电极线431)平行的边的长度，所述第二电极线(第二电极线412或第二电极线432)的相邻两个断口44之间的距离为所述像素区域23与所述第二电极线(第二电极线412或第二电极线432)平行的边的N倍的长度，其中N为大于或等于1的自然数，以使至少部分所述像素区域23为非封闭区域。所述断口44将所述电极线(包括第一电极线及第二电极线)分为多条间隔设置的线段。本实施例中，所述N为2，且所述第一电极层41的第二电极线412上的断口与所述第二电 极层43的第二电极线432上的断口44错开设置，使得位于同一层的具有断口44的第一电极线的线段与具有断口44第二电极线的线段相交形成“L”形的结构，所述第一电极层41的所述“L”形的结构与所述第二电极层43的所述“L”形的结构方向镜像设置并稍微错开。可以理解的是，所述第二电极线(第二电极线412或第二电极线432)也可以均为连续线或者部分为连续线。
本实施例中，通过将所述第一电极层41及所述第二电极层43上的电极线(包括第一电极线及第二电极线)均设置断口44，从而使得每个所述像素区域23均为未封闭状态，使得相较于现有技术，所述触控层40与所述显示面板10的阴极层14之间的电容负载减小，从而减小背景电容值Cm。并且，通过将所述第一电极层41及所述第二电极层43上的电极线均设置断口24，从而尽量减小所述第一电极层41与所述第二电极层43的电极线之间的节点数，以进一步减小背景电容值Cm。并且，通过将所述第一电极层41以及第二电极层43的第一电极线411或者第二电极线432设于相同的相邻的发光单元之间，以提高所述感应变化电容值ΔCm的值，进而提高所述感应变化电容值ΔCm与背景电容值Cm的比值，提升所述触控显示面板100的触控效果。
进一步的，请重新参阅图2，本发明中，未设置有所述断口的所述第一电极线及所述第二电极线均通过连接线50与控制芯片60电连接。请参阅图13，每条所述连接线50包括第一连接线51及第二连接线52，所述第二连接线52层叠于所述第一连接线51上并与所述第二连接线52间隔设置。所述第一连接线51与所述第二连接线52之间通过绝缘层53间隔开。所述绝缘层上设有多个间隔设置的过孔54，位于所述绝缘层两侧的所述第一连接线51与第二连接线52之间通过所述多个过孔54进行电连接。
通过将多个过孔54将所述第一连接线51与第二连接线52连接，相当于多个所述过孔54分别将所述第一连接线51分为多个第一区段511，并将所述第二连接线52分为多个第二区段521，并通过所述过孔54将所述第一区段511与所述第二区段521并联后再进行串联。从而使得每条所述连接线50的电阻大大的降低，从而使得所述控制芯片的控制信号经过所述连接线50时损耗减小，实现所述触控层20更为灵敏的控制。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发 明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
