具体实施方式
下文中将结合附图对本公开的实施例进行详细说明。注意，实施方式可以以多个不同形式来实施。所属技术领域的普通技术人员可以很容易地理解一个事实，就是方式和内容可以在不脱离本公开的宗旨及其范围的条件下被变换为各种各样的形式。因此，本公开不应该被解释为仅限定在下面的实施 方式所记载的内容中。在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。为了保持本公开实施例的以下说明清楚且简明，本公开省略了部分已知功能和已知部件的详细说明。本公开实施例附图只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计
在附图中，有时为了明确起见，夸大表示了各构成要素的大小、层的厚度或区域。因此，本公开的一个方式并不一定限定于该尺寸，附图中各部件的形状和大小不反映真实比例。此外，附图示意性地示出了理想的例子，本公开的一个方式不局限于附图所示的形状或数值等。
本说明书中的“第一”、“第二”、“第三”、第1、第2、第3等序数词是为了避免构成要素的混同而设置，而不是为了在数量方面上进行限定的。
在本说明书中，为了方便起见，使用“中部”、“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示方位或位置关系的词句以参照附图说明构成要素的位置关系，仅是为了便于描述本说明书和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。构成要素的位置关系根据描述各构成要素的方向适当地改变。因此，不局限于在说明书中说明的词句，根据情况可以适当地更换。
在本说明书中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解。例如，可以是固定连接，或可拆卸连接，或一体地连接；可以是机械连接，或电连接；可以是直接相连，或通过中间件间接相连，或两个元件内部的连通。对于本领域的普通技术人员而言，可以根据情况理解上述术语在本公开中的含义。
在本说明书中，晶体管是指至少包括栅电极、漏电极以及源电极这三个端子的元件。晶体管在漏电极(漏电极端子、漏区域或漏电极)与源电极(源电极端子、源区域或源电极)之间具有沟道区域，并且电流能够流过漏电极、沟道区域以及源电极。注意，在本说明书中，沟道区域是指电流主要流过的区域。
在本说明书中，第一极可以为漏电极、第二极可以为源电极，或者第一 极可以为源电极、第二极可以为漏电极。在使用极性相反的晶体管的情况或电路工作中的电流方向变化的情况等下，“源电极”及“漏电极”的功能有时互相调换。因此，在本说明书中，“源电极”和“漏电极”可以互相调换。
在本说明书中，“电连接”包括构成要素通过具有某种电作用的元件连接在一起的情况。“具有某种电作用的元件”只要可以进行连接的构成要素间的电信号的授受，就对其没有特别的限制。“具有某种电作用的元件”的例子不仅包括电极和布线，而且还包括晶体管等开关元件、电阻器、电感器、电容器、其它具有各种功能的元件等。
在本说明书中，“平行”是指两条直线形成的角度为-10°以上且10°以下的状态，因此，也包括该角度为-5°以上且5°以下的状态。另外，“垂直”是指两条直线形成的角度为80°以上且100°以下的状态，因此，也包括85°以上且95°以下的角度的状态。
在本说明书中，“膜”和“层”可以相互调换。例如，有时可以将“导电层”换成为“导电膜”。与此同样，有时可以将“绝缘膜”换成为“绝缘层”。
本公开中的“约”，是指不严格限定界限，允许工艺和测量误差范围内的数值。

目前，Touch on TFE结构主要包括柔性多层覆盖表面式(Flexible Multi Layer On Cell，简称FMLOC)结构和柔性单层覆盖表面式(Flexible Single Layer On Cell，简称FSLOC)结构。FMLOC结构是基于互容检测的工作原理，一般采用两层金属形成驱动(Tx)电极和感应(Rx)电极，集成电路(IC)通过检测驱动电极和感应电极间的互容来实现触控动作。FSLOC结构是基于自容(或电压)检测的工作原理，一般采用单层金属形成触控电极，集成电路通过检测触控电极自容(或电压)来实现触控动作。

图3为一种像素驱动电路的工作时序图。下面通过图2示例的像素驱动电路的工作过程说明本公开示例性实施例，图2中的像素驱动电路包括7个晶体管(第一晶体管T1到第六晶体管T7)、1个存储电容C和7个信号线(数据信号线D、第一扫描信号线S1、第二扫描信号线S2、发光信号线E、初始信号线INIT、第一电源线VDD和第二电源线VSS)，7个晶体管均为P型晶体管。
在示例性实施方式中，像素驱动电路的工作过程可以包括：
第一阶段A1，称为复位阶段，第二扫描信号线S2的信号为低电平信号，第一扫描信号线S1和发光信号线E的信号为高电平信号。第二扫描信号线S2的信号为低电平信号，使第一晶体管T1导通，初始信号线INIT的信号提供至第二节点N2，对存储电容C进行初始化，清除存储电容中原有数据电压。第一扫描信号线S1和发光信号线E的信号为高电平信号，使第二晶体管T2、第四晶体管T4、第五晶体管T5、第六晶体管T6和第七晶体管T7断开，此阶段OLED不发光。
第二阶段A2、称为数据写入阶段或者阈值补偿阶段，第一扫描信号线 S1的信号为低电平信号，第二扫描信号线S2和发光信号线E的信号为高电平信号，数据信号线D输出数据电压。此阶段由于存储电容C的第二端为低电平，因此第三晶体管T3导通。第一扫描信号线S1的信号为低电平信号使第二晶体管T2、第四晶体管T4和第七晶体管T7导通。第二晶体管T2和第四晶体管T4导通使得数据信号线D输出的数据电压经过第一节点N1、导通的第三晶体管T3、第三节点N3、导通的第二晶体管T2提供至第二节点N2，并将数据信号线D输出的数据电压与第三晶体管T3的阈值电压之差充入存储电容C，存储电容C的第二端(第二节点N2)的电压为Vd-|Vth|，Vd为数据信号线D输出的数据电压，Vth为第三晶体管T3的阈值电压。第七晶体管T7导通使得初始信号线INIT的初始电压提供至OLED的第一极，对OLED的第一极进行初始化(复位)，清空其内部的预存电压，完成初始化，确保OLED不发光。第二扫描信号线S2的信号为高电平信号，使第一晶体管T1断开。发光信号线E的信号为高电平信号，使第五晶体管T5和第六晶体管T6断开。
第三阶段A3、称为发光阶段，发光信号线E的信号为低电平信号，第一扫描信号线S1和第二扫描信号线S2的信号为高电平信号。发光信号线E的信号为低电平信号，使第五晶体管T5和第六晶体管T6导通，第一电源线VDD输出的电源电压通过导通的第五晶体管T5、第三晶体管T3和第六晶体管T6向OLED的第一极提供驱动电压，驱动OLED发光。
在像素驱动电路驱动过程中，流过第三晶体管T3(驱动晶体管)的驱动电流由其栅电极和第一极之间的电压差决定。由于第二节点N2的电压为Vdata-|Vth|，因而第三晶体管T3的驱动电流为：
I＝K*(Vgs-Vth) 2＝K*[(Vdd-Vd+|Vth|)-Vth] 2＝K*[(Vdd-Vd] 2
其中，I为流过第三晶体管T3的驱动电流，也就是驱动OLED的驱动电流，K为常数，Vgs为第三晶体管T3的栅电极和第一极之间的电压差，Vth为第三晶体管T3的阈值电压，Vd为数据信号线D输出的数据电压，Vdd为第一电源线VDD输出的电源电压。

图18为本公开示例性实施例一种金属网格形成触控电极的示意图，以触控区域包括24个自容式触控电极为例。如图18所示，在示例性实施方式中，矩形状的第一电极区可以形成4行*4列触控电极400，每个触控电极400的形状可以为波浪形边缘的方块状。圆冠形状的第二电极区、第三电极区、第四电极区和第五电极区可以分别形成2个触控电极400，每个触控电极400的形状可以为波浪形边缘的三角块状。
图19为图18中一个波浪形边缘方块状触控电极的放大图。如图19所示，在示例性实施方式中，波浪形边缘的方块状触控电极可以包括重复且连续设置由多个重复单元，每个重复单元可以包括前述的第一网格图案、第二网格图案和第三网格图案，每个网格图案可以是由曲线状的横边和/或曲线状的竖边构成的环形，即每个网格图案可以包括第一曲线环形、第二曲线环形、第三曲线环形和第四曲线环形中的一个。由于网格图案中横边和竖边为曲线状，且第一方向D1上相邻重复单元中相同网格图案的竖边的曲率方向(凸出方向)相反，第二方向D2上相邻重复单元中相同网格图案的横边的曲率方向相反，因而由网格图案组成的触控电极中，触控电极的边缘为波浪形。在示例性实施方式中，至少一个触控电极中可以设置至少一个虚拟区，虚拟区的形状可以与触控电极的形状相似，虚拟区的边缘为波浪形，本公开在此不做限定
在示例性实施方式中，触控电极400可以至少包括沿着第二方向D2延伸且为波浪状的第一电极边缘和沿着第一方向D1延伸且为波浪状的第二电极边缘。由于网格图案中横边与第二方向D2的夹角约为12°至18°，竖边与第一方向D1的夹角约为12°至18°，因而在第一电极边缘与第二电极边缘的交界处，第一电极边缘的切线与第二方向D2的夹角α可以约为12°至18°，第二电极边缘的切线与第一方向D1的夹角β可以约为12°至18°。在示例性实施方式中，夹角α可以等于夹角β。例如，夹角α和夹角β可以约为14°左右。
一种触控面板的设计中，形成触控电极的网格图案的形状与显示基板上 子像素中发光区域的形状基本上相同。例如，子像素中发光区域为矩形时，网格图案也是矩形。这样，当显示基板上子像素在行方向和列方向整齐排布时，触控面板上网格图案的排布十分规整，不仅使得构成网格图案的金属线通常是长距离的直线，而且形成直线状边缘的触控电极。研究表明，由于直线状金属线具有强反射特性，且整齐排布的金属线之间容易产生干涉，因而不仅会导致宏观下触控面板的触控电极和信号引线出现可视化(visibility)，特别是触控电极直线状边缘的可视化，而且会导致微观下触控面板在一个方向上或一个区域内出现亮度差异，降低了显示品质，影响了用户体验。
本公开示例性实施例提供的显示面板，通过将触控面板上网格图案的横边和/或竖边设置成曲线，且不同位置的曲线具有不同的曲率方向，使得构成网格图案的金属线为波浪形弯折线，进而形成波浪形边缘的触控电极，不仅减弱了金属线的反射，有效降低了宏观下触控电极和信号引线的可视化，特别是降低了触控电极边缘的可视化，而且减弱了金属线之间的干涉，有效降低了微观下一个方向上或一个区域内的亮度差异，有效提高了显示品质。本公开示例性实施例通过将网格图案中的横边与第二方向的夹角和竖边与第一方向的夹角设置成12°至18°左右，使得触控电极的第一电极边缘与第二方向的夹角α约为12°至18°，第二电极边缘与第一方向的夹角β约为12°至18°，最大限度地提高了消影效果，最大限度地降低了触控电极边缘的可视化。本公开示例性实施例通过在行方向上将相邻的出射相同颜色光线的子像素对应的网格图案的横边设置成曲率方向相反，在列方向上将相邻的出射相同颜色光线的子像素对应的网格图案的竖边设置成曲率方向相反，使得相邻的出射相同颜色光线的子像素对应的网格图案的横边和竖边反向弯折，有效消除了因网格图案反光导致的色偏，有利于提高显示品质。本公开示例性实施例通过将网格图案的横边或竖边与子像素发光区域之间的最小距离设置成8μm至10μm，有效降低了网格图案影响出光性能的风险。
图20为一种触控面板中触控走线的示意图，示意了触控区域100和边框区域200交界区域的触控走线的结构，以矩形网格图案为例。在示例性实施方式中，为了在触控区域100形成相互绝缘的多条触控走线，可以通过在金属网格上设置切口的方式实现。在示例性实施方式中，网格图案上设置有多 个切口，多个切口断开网格图案的金属线，实现一条触控走线的网格图案与相邻的另一条触控走线的网格图案的隔离，切口可以理解为切割金属线的假想线，多个网格图案上的多个切口可以形成一条信号传输通道。图20所示，黑色块表示切口，深色和浅色的填充分别表示由多个切口限定的触控走线410。在示例性实施方式中，边框区域200的信号引线210可以采用金属线形式，边框区域200的多条信号引线210与触控区域100的多条触控走线410对应连接。

图26所示的穿插结构仅仅是一种示例性说明，在示例性实施方式中，穿插结构可以修改或等同替换成相应结构。例如，可以在右侧的第二接地线的端部设置有穿插部以及在右侧的第二辅助接地线的端部设置有辅助穿插部。又如，穿插段可以设置在第二接地线远离触控区域的一侧。再如，辅助穿插段可以设置在第二辅助接地线靠近触控区域的一侧，本公开在此不做限定。
图27为本公开示例性实施例一种边框区域中引线汇集区的示意图。如图27所示，多条信号引线210在边框区域的引线汇集区汇集在一起后，沿着第一方向D1向着绑定区域延伸。在中心线O的两侧，多条信号引线210设置在两条接地线220之间，接地线220可以实现对信号引线的屏蔽，使得静电和干扰信号不会影响信号引线。
本公开示例性实施例通过在接地线和辅助接地线的交汇位置形成穿插结构，穿插结构不仅消除了接地线之间的间隙，增加了外部静电和外部干扰信号进入到触控区域的路径长度，也增加了外部静电和外部干扰信号进入触控区域内部的难度，有效降低了外部静电和外部干扰信号对信号引线和触控电极的影响，提高了触控性能，而且接地线交叠可以有利于静电电荷释放，减少了接地线上静电电荷的积累，降低了接地线的静电电流，最大限度地减少了接地线对触控性能的影响。
一种触控面板中，通常在触控区域的两侧设置接地线，每侧的接地线环绕该侧的触控区域后延伸到中心线位置，两侧的接地线的第一端相对设置，且间隔一段距离。研究表明，该接地线结构虽然可以为触控区域产生的静电提供一条静电释放路径，但由于两侧的接地线的第一端之间存在一段无屏蔽区域，外部静电和外部干扰信号容易从这个无屏蔽区域进入到触控区域，因而屏蔽外部静电和外部干扰信号的能力较低，降低了触控性能，影响了用户体验。本公开示例性实施例提供的触控面板，通过在接地线和辅助接地线的 交汇位置形成穿插结构，穿插结构不仅消除了接地线之间的间隙，增加了外部静电和外部干扰信号进入到触控区域的路径长度，也增加了外部静电和外部干扰信号进入触控区域内部的难度，有效降低了外部静电和外部干扰信号对信号引线和触控电极的影响，提高了触控性能，而且接地线交叠可以有利于静电电荷释放，减少了接地线上静电电荷的积累，降低了接地线的静电电流，最大限度地减少了接地线对触控性能的影响。本公开示例性实施例通过设置辅助接地线，辅助接地线与接地线连接并形成分叉结构，形成双线结构的接地线，增加了一道屏蔽结构，外部静电和外部干扰信号可以被两次屏蔽，增加了外部静电和外部干扰信号进入触控区域内部的难度，进一步提高了接地线屏蔽静电和干扰信号的能力，提高了触控性能。本公开示例性实施例通过在接地线与辅助接地线之间的空出空间设置虚拟线段，保证了刻蚀均一性，提高了制备工艺精度，提高了良品率。
