图1A为根据一些实施例的触控显示面板的结构图。
如图1A所示,本公开的实施例提供了一种触控显示面板(英文全称:Touch Screen Panel,英文简称:TSP)200。可以理解地,触控显示面板200用于显示图像信息。示例性的,触控显示面板200可以显示静态图像信息,例如图片或者照片等,也可以显示动态图像,例如视频或者游戏画面等。
随着显示技术的快速发展,触控显示面板200在车载显示、手机显示、平板电脑显示、笔记本电脑显示及电视显示等领域具有广阔的应用 空间。可以理解地,触控显示面板200具有触控功能。
在一些示例中,触控显示面板200为有机发光二极管显示器(英文全称:Organic Light-Emitting Diode,英文简称:OLED)、量子点电致发光显示器(Quantum dot Light Emitting Diodes,英文简称QLED)和液晶显示器(英文全称:Liquid Crystal Display,英文简称:LCD)中的任一个。
在一些示例中,如图1A所示,触控显示面板200具有显示区AA和周边区CC,周边区CC围设于显示区AA。可以理解地,显示区AA用于显示图像信息,周边区CC用于放置与显示区AA电连接的引线或者驱动装置等。
在一些示例中,触控显示面板200的形状可以为方形、圆形或者其他形状。显示区AA的形状与触控显示面板200的形状可以相同,也可以不同。
在一些示例中,如图1A所示,触控显示面板200包括多个子像素220。子像素220是触控显示面板200进行画面显示的最小单元。多个子像素220位于触控显示面板200的显示区AA内,且多个子像素220阵列排布,使得显示区AA能够实现图像显示功能。
在一些示例中,如图1A所示,多个子像素220沿第一方向X1排列成多列,且沿第二方向Y1排列成多行,第一方向X1和第二方向Y1相交。在一些示例中,第一方向X1为水平方向,第二方向Y1为竖直方向。示例性的,第一方向X1和第二方向Y1垂直。
可以理解地,每个子像素220可显示一种单一的颜色,例如红色、绿色或蓝色。触控显示面板200可以包括多个红色子像素、多个绿色子像素和多个蓝色子像素。通过调节不同颜色的子像素220的亮度(灰阶),即可得到不同强度的红光、绿光和蓝光。而不同强度的红光、绿光和蓝光中的至少两者进行叠加,又可以显示出更多颜色的光,从而实现了触控显示面板200的全彩化显示。
图1B为根据另一些实施例的触控显示面板的结构图。
如图1B所示,触控显示面板200包括显示基板210和触控功能层100。显示基板210具有显示侧,触控功能层100位于显示基板210的显示侧。
可以理解地,显示基板210的显示侧用于显示图像信息。显示基板210包括多个子像素220,使得显示基板220能够实现显示功能。触控功能层100能够检测到触碰位置。这样一来,将触控功能层100设置在显示基板210的显示侧,就能够使得触控显示面板200实现触控功能。
在一些示例中,触控功能层100位于触控显示面板200的显示区AA,使得显示区AA能够实现触控功能。示例性的,触控功能层100为透明材质, 避免触控功能层100对显示区AA内显示的图像信息造成阻挡。
下面继续参照图1B,以显示基板210为OLED显示基板为例,对显示基板210的结构进行举例说明。
在一些示例中,如图1B所示,每个子像素220包括发光器件EL和像素驱动电路,像素驱动电路与发光器件EL电连接,用于驱动发光器件EL发光。示例性的,像素驱动电路包括多个薄膜晶体管(英文全称:Thin Film Transistor,英文简称:TFT)T和至少一个电容。
示例性的,如图1B所示,显示基板210包括衬底211和多层导电膜层216,像素驱动电路位于多层导电膜层216内。
在一些示例中,衬底211为柔性材料,使得显示基板210能够弯曲,从而使得触控显示面板200能够实现曲面显示、折叠显示或滑卷显示等功能。在另一些示例中,衬底211为硬性材料。
示例性的,衬底211的材料可以为聚酰亚胺(英文全称:Polyimide,英文简称:PI)、聚碳酸酯(英文全称:Polycarbonate,英文简称:PC)或者聚氯乙烯(英文全称:Polyvinyl Chloride,英文简称:PVC)中的任一个。
示例性的,如图1B所示,多层导电膜层216位于衬底211的同一侧,且多层导电膜层216层叠设置。在一些示例中,如图1B所示,多层导电膜层216包括依次远离衬底211的有源膜层212、第一栅金属层Gate1、第二栅金属层Gate2、第一源漏金属层SD1和第二源漏金属层SD2。
示例性的,有源膜层212和第一栅金属层Gate1可以用于形成多个薄膜晶体管T中的一部分薄膜晶体管T(一个、两个或者更多个),有源膜层212和第二栅金属层Gate2可以用于形成多个薄膜晶体管T中的另一部分薄膜晶体管T(一个、两个或者更多个)。第一栅金属层Gate1和第二栅金属层Gate2可以用于形成至少一个电容。
在一些示例中,多层导电膜层216之间设置有绝缘膜层(图中未示出,例如栅绝缘层、钝化层、有机层等),起到对于相邻的两层导电膜层216进行电隔离的作用。
需要说明的是,本公开的实施例对有源膜层212的数量不做进一步限定。例如,本公开的一些示例中,显示基板210可以仅包括一层有源膜层212,该有源膜层212的材料可以包括金属氧化物、也可以包括低温多晶硅。本公开的另一些示例中,显示基板210也可以包括两层有源膜层212,其中,一层有源膜层212的材料包括金属氧化物,另一层有源膜层212的材料包括低温多 晶硅。
在一些示例中,多层导电膜层216还可以包括第三栅金属层(图中未示出)。示例性的,第一栅金属层Gate1、第二栅金属层Gate2、第三栅金属层、第一源漏金属层SD1和第二源漏金属层SD2,沿远离衬底211的方向依次层叠设置。
由上述可知,像素驱动电路与发光器件EL电连接,用于驱动发光器件EL发光。下面继续参照图1B,对发光器件EL进行举例说明。
在一些示例中,如图1B所示,发光器件EL位于多层导电膜层216远离衬底211的一侧。由于子像素220包括位于多层导电膜层210中的像素驱动电路,和位于多层导电膜层216远离衬底211一侧的发光器件EL,也即是,多个子像素220位于衬底211的一侧。
示例性的,如图1B所示,发光器件EL包括沿远离衬底211的方向依次设置的阳极层AND、发光功能层EML和阴极层CTD。
在一些示例中,发光功能层EML包括多个间隔设置的有效发光部,有效发光部用于发光。示例性的,有效发光部包括电致发光材料。可以理解地,电致发光指的是有机半导体材料在电场驱动下,通过载流子注入、传输、电子和空穴结合形成激子,进而辐射复合导致发光的现象。
在一些示例中,如图1B所示,显示基板210还包括像素界定层PDL,像素界定层PDL包括多个开口区,一个有效发光部位于一个开口区内,使得多个有效发光部能够间隔设置。
可以理解地,多个有效发光部中的一部分用于发红光,另一部分用于发绿光,又一部分用于发蓝光。示例性的,可以选择不同的电致发光材料,使得有效发光部能够发不同颜色的光。可以理解地,发红光的有效发光部、发绿光的有效发光部和发蓝光的有效发光部三者的数量可以相同,也可以不同。
示例性的,发红光的有效发光部、发绿光的有效发光部和发蓝光的有效发光部可以混合阵列排布,这样一来,通过控制发不同的有效发光部的发光强度,就能够得到不同强度的红光、绿光和蓝光。将不同强度的红光、绿光和蓝光混合,即可使得触控显示面板200实现全彩化图像显示。
在一些示例中,一个像素驱动电路通过阳极层AND与一个有效发光部电连接,使得各个像素驱动电路能够通过阳极层AND,分别向各个有效发光部提供驱动电流,也即是使得多个有效发光部进行独立发光,减小多个有效发光部之间的相互干扰,提高触控显示面板200的显示效果。可以理解地,通过调节像素驱动电路向有效发光部提供的驱动电流的大小,能够对有效发光 部的发光亮度起到调节作用。
在一些示例中,阳极层AND为金属材料,例如铜或者银等。阴极层CTD为透明材料,例如透明氧化铟锡(英文全称:Indium Tin Oxide,英文简称:ITO)或者透明氧化铟锌(英文全称:Indium Zinc Oxide,英文简称:IZO)等,使得有效发光部发射的光线能够经由阴极层CTD射出,即此时显示基板210为顶发光显示基板。
在另一些示例中,阳极层AND为透明材料,例如ITO或者IZO等,阴极层CTD为金属材料,例如铜或者银等,使得有效发光部发射的光线能够经由阳极层AND射出,即此时显示基板210为底发光显示基板。
在又一些示例中,阳极层AND和阴极层CTD均为透明材料,例如ITO或者IZO等,使得有效发光部发射的光线可以经由阳极层AND和阴极层CTD射出,即此时显示基板210为双面发光显示基板。
本公开的实施例以显示基板210为顶发光显示基板为例,继续举例说明。可以理解地,触控功能层100位于显示基板210的显示侧,也即是,触控功能层100位于阳极层AND远离阴极层CTD的一侧。
在一些示例中,沿阳极层AND至有效发光部的方向,在阳极层AND和有效发光部之间设置有空穴注入层(英文全称:Hole Inject Layer,英文简称:HIL)、空穴传输层(英文全称:Hole Transport Layer,英文简称:HTL)和电子阻挡层(英文全称:Electron Blocking Layer,英文简称:EBL)中的至少一个。沿阴极层CTD至有效发光部的方向,在阴极层CTD和有效发光部之间设置有电子注入层(英文全称:Electron Inject Layer,英文简称:EIL)、电子传输层(英文全称:Electron Transport Layer,英文简称:ETL)和空穴阻挡层(英文全称:Hole Blocking Layer,英文简称:HBL)中的至少一个。上述设置方式,提高了有效发光部的发光可靠性。
在一些示例中,如图1B所示,显示基板210还包括平坦层213,平坦层213位于多层导电膜层216和发光器件EL之间,也即是发光器件EL位于平坦层213远离多层导电膜层216的一侧。可以理解地,平坦层213远离多层导电膜层216的一侧表面为光滑或者近似光滑的平面。
在一些示例中,多层导电膜层216中除了包括像素驱动电路之外,还包括多条信号引线(例如数据线和电源信号线等)。多条信号引线与像素驱动电路和发光器件EL电连接,用于传输电信号,使得像素驱动电路能够驱动发光器件EL发光,实现不同灰阶的显示。
在一些示例中,如图1B所示,显示基板210还包括封装层214。封装层 214位于发光器件EL远离衬底211的一侧。可以理解地,封装层214能够覆盖发光器件EL,将发光器件EL包覆起来,以避免外界环境中的水汽和氧气进入发光器件EL,起到保护发光器件EL的作用。
图1C为根据一些实施例的触控功能层的结构图。图1D为根据一些实施例的电极板的结构图。下面参照图1C和图1D,对触控功能层100进行举例说明。
在一些示例中,如图1C所示,触控功能层100包括多个触控电极110和多条触控引线120,多条触控引线120与多个触控电极110电连接。
示例性的,触控电极110为Metal Mesh(中文名称:金属网格)触控电极,触控显示面板200为Metal Mesh TSP(中文名称:金属网格触控显示面板)。
示例性的,如图1C所示,多个触控电极110包括多个第一触控电极111和多个第二触控电极112。多个第一触控电极111沿第一方向X1间隔排布,且均沿与第一方向X1交叉的第二方向Y1延伸。可以理解地,沿第一方向X1排布的多个第一触控电极111之间相互绝缘。
示例性的,如图1C所示,多个第二触控电极112沿第二方向Y1间隔排布,且多个第二触控电极112均沿第一方向X1延伸。可以理解地,沿第二方向Y1排布的多个第二触控电极112之间相互绝缘。示例性的,第一方向X1与第二方向Y1垂直。
在一些示例中,第一触控电极111为Tx(英文全称:Transmit,中文名称:触控发射电极),第二触控电极112为Rx(英文全称:Receive,中文名称:触控接收电极)。在另一些示例中,第一触控电极111为Rx(英文全称:Receive,中文名称:触控接收电极),第二触控电极112为Tx(英文全称:Transmit,中文名称:触控发射电极)。
在一些示例中,如图1C所示,多个第一触控电极111和多个第二触控电极112整体所在的最小封闭图形区域的边缘,与显示区AA的边缘相重合。
示例性的,如图1D所示,多个第二触控电极112与多个第一触控电极111彼此交叉且相互绝缘。可以理解地,多个第二触控电极112与多个第一触控电极111彼此交叉,也即是多个第一触控电极111在显示基板210上的正投影,与多个第二触控电极112在显示基板210上的正投影彼此交叉。
可以理解地,如图1C所示,由于多个第一触控电极111和多个第二触控电极112彼此交叉且相互绝缘,使得多个第一触控电极111和多个第二触控电极112的各个交叉位置处可以构成电容单元(也即是触控图案,英文名称: Pattern)113。示例性的,多个电容单元113位于显示区AA内,且阵列排布。
在一些示例中,电容单元113为正方形或者近似正方形,示例性的,正方形电容单元113的边长可以为4mm。
可以理解地,当人手指触碰或者触控笔等触碰到电容单元113时,人手指或者触控笔的电容就会叠加至对应的电容单元113上,导致电容单元113的电容值发生变化。这样一来,通过获取多个电容单元113的电容值,即可确定出触碰位置,从而实现触控功能。
可以理解地,由于多个触控电极110和多条触控引线120电连接,而多个触控电极110能够构成电容单元113,使得多条触控引线120能够与多个电容单元113电连接。
图1E为根据一些实施例的电容单元的结构图。下面参照图1D和图1E,对触控电极进行举例说明。

示例性的,如图1E所示,第二触控电极112包括多个触控子电极1121和多个桥接部1122。多个触控子电极1121沿第一方向X1间隔设置,桥接部1122位于任意相邻的两个触控子电极1121之间,且与任意相邻的两个触控子电极1121电连接,使得第二触控电极112能够沿第一方向X1延伸。

示例性的,如图1E所示,连接结构1112a在显示基板210上的正投影,与桥接部1122a在显示基板210上的正投影相交叉。需要说明的是,连接结构1112a和桥接部1122a,仅用于限定在显示基板210上的正投影相交叉的连接结构1112和桥接部1122,不对连接结构1112和桥接部1122做进一步限定。
如图1E所示,多个触控结构1111包括相邻设置的第一个触控结构1111a 和第二个触控结构1111b,连接结构1112a位于第一个触控结构1111a和第二个触控结构1111b之间,且分别与第一个触控结构1111a和第二个触控结构1111b电连接。
需要说明的是,第一个触控结构1111a和第二个触控结构1111b仅用于区分与连接结构1112a电连接且相邻设置的两个触控结构1111,不对触控结构1111做进一步限定。
如图1E所示,多个触控子电极1121包括第一个触控子电极1121a和第二个触控子电极1121b,桥接部1122a位于第一个触控子电极1121a和第二个触控子电极1121b之间,且分别与第一个触控子电极1121a和第二个触控子电极1121b电连接。
需要说明的是,第一个触控子电极1121a和第二个触控子电极1121b仅用于区分与桥接部1122a电连接且相邻设置的两个触控子电极1121,不对触控子电极1121做进一步限定。
示例性的,如图1E所示,第一个触控结构1111a的第一部分114a和第二个触控结构1111b的第一部分114b相对设置,第一个触控子电极1121a的第二部分115a和第二个触控子电极1121b的第二部分115b相对设置。第一个触控结构1111a的第一部分114a、第二个触控结构1111b的第一部分114b、第一个触控子电极1121a的第二部分115a、第二个触控子电极1121b的第二部分115b、连接结构1112a和桥接部1122a能够构成电容单元113。
需要说明的是,第一部分114a和第一部分114b仅用于区分第一个触控结构1111a的第一部分114和第二个触控结构1111b的第一部分114,不对第一部分114做进一步限定。第二部分115a和第二部分115b仅用于区分第一个触控子电极1121a的第二部分115和第二个触控子电极1121b的第二部分115,不对第二部分115做进一步限定。
由上述可知,多个触控电极110与多条触控引线120电连接,在一些示例中,如图1C所示,多条触控引线120包括第一类触控引线120a和第二类触控引线120b。
示例性的,第一类触控引线120a的数量为多条,至少一条第一类触控引线120a,与一个第一触控电极111电连接。在一些示例中,如图1C所示,两条第一类触控引线120a,分别与同一个第一触控电极111沿第二方向Y1的两端电连接。在另一些示例中,一条第一类触控引线120a与一个第一触控电极111沿第二方向Y1的一端电连接。

需要说明的是,第一类触控引线120a和第二类触控引线120b仅用于区分与第一触控电极111和第二触控电极112电连接的触控引线120,不对触控引线120做进一步限定。
在一些示例中,如图1C所示,多个触控电极110位于显示区AA,多条触控引线120位于周边区CC。
示例性的,多个触控电极110的材质可以为透明氧化铟锡(英文全称:Indium Tin Oxide,英文简称:ITO)或者透明氧化铟锌(英文全称:Indium Zinc Oxide,英文简称:IZO)等,减小触控电极110对显示区AA内显示的图像信息造成的影响。
可以理解地,随着触控显示面板200的尺寸分辨率(英文全称:Pixels Per Inch,英文简称PPI)越来越高,触控显示面板200的周边区CC内需要布置的引线数量(例如触控引线120、电源信号线或者与其他引线)越来越多,导致周边区CC的宽度增大,从而导致触控显示面板200的边框(例如沿第一方向X1两侧的边框,以及沿第二方向Y1两侧的边框)宽度增大,不利于触控显示面板200的窄边框,影响了触控显示面板200的视觉效果。
图2A为根据又一些实施例的触控显示面板的结构图。
基于此,本公开的实施例提供了一种触控显示面板200。下面参照图2A,对本公开的实施例提供的触控显示面板200进行举例说明。
在一些实施例中,如图2A所示,触控显示面板200具有显示区AA和位于显示区一侧的扇出区BB。可以理解地,显示区AA用于显示图像信息,扇出区BB用于放置与显示区AA电连接的引线。
在一些示例中,在触控显示面板200的使用状态下,扇出区BB位于显示区AA的下方,也即是在一些使用状态下,扇出区BB可以相对于显示区AA更靠近地面。
由上述可知,触控显示面板200的周边区CC围设于显示区AA。示例性的,如图2A所示,扇出区BB位于触控显示面板200的周边区CC内。
如图2A所示,显示区AA包括第一显示区AA1和位于第一显示区AA1周围的第二显示区AA2,可以理解地,第一显示区AA1和第二显示区AA2均能够显示图像信息。
第二显示区AA2位于第一显示区AA1的周围,示例性的,如图2A所示,第二显示区AA2的靠近第一显示区AA1一侧的边缘,与第一显示区AA1靠近第二显示区AA2一侧的边缘相重合,使得第二显示区AA2能够围设于第一显示区AA1,并且与第一显示区AA1相邻设置。
扇出区BB位于显示区AA的一侧,在一些示例中,扇出区BB与第二显示区AA2相邻设置。示例性的,扇出区BB靠近第二显示区AA2一侧的边缘,与第二显示区AA2靠近扇出区BB一侧的边缘相重合。
需要说明的是,本公开的说明书附图中,以图2A为例,扇出区BB与第二显示区AA2的边缘相互分离,仅仅是为了便于示出扇出区BB和第二显示区AA2,不对扇出区BB和第二显示区AA2做进一步限定。
触控显示面板200包括显示基板210和触控功能层100。显示基板210具有显示侧,触控功能层100位于显示基板210的显示侧。触控功能层100包括多个触控电极110和多条触控引线120,多条触控引线120与多个触控电极110电连接。
可以理解地,本公开的上述实施例已经对显示基板210、触控电极110、以及多条触控引线120和多个触控电极110的电连接关系等进行了举例说明,在此不再赘述。
如图2A所示,多个触控电极110位于第一显示区AA1,多条触控引线120经由第二显示区AA2延伸至扇出区BB。
可以理解地,多个触控电极110位于第一显示区AA1,使得第一显示区AA1内能够实现触控功能。多条触控引线120与多个触控电极110电连接,示例性的,如图2A所示,多条触控引线120的一端位于第一显示区AA1,且与触控电极110电连接,另一端经由第二显示区AA2延伸至扇出区BB。
可以理解地,设置多条触控引线120经由第二显示区AA2延伸至扇出区BB,避免了触控引线120占用周边区CC内的空间,减小触控显示面板200的周边区CC的宽度,从而能够减小触控显示面板200的侧边框(例如沿第一方向X1两侧的边框,以及沿第二方向Y1两侧的边框)宽度,利于实现触控显示面板200的窄边框,使得触控显示面板200能够最大化显示区AA,并且最小化周边区CC,提高触控显示面板200的视觉效果。
在一些示例中,设置多条触控引线120经由第二显示区AA2延伸至扇出区BB,使得触控显示面板200沿第一方向X1方向的两侧、以及触控显示面板200远离扇出区BB的一侧能够实现无边框,提高触控显示面板200的视觉效果。
并且,本公开的实施例中,多个触控电极110位于第一显示区AA1,多条触控引线120经由第二显示区AA2延伸至扇出区BB,减小了触控引线120与触控电极110之间的相互影响,提高触控显示面板200的可靠性。
由上述可知,多个第一触控电极111和多个第二触控电极112彼此交叉且相互绝缘,从而能够在各个交叉位置处构成电容单元113。示例性的,如图2A所示,多个电容单元113能够沿第一方向X1和第二方向Y1阵列排布,并且沿第一方向X1排布的多个电容单元113电连接,沿第二方向Y1排布的多个电容单元113电连接。
图2B为根据另一些实施例的触控功能层的结构图。
由上述可知,如图2B所示,多个触控电极110包括多个第一触控电极111和多个第二触控电极112,多条触控引线120中的一部分(两条或者更多条)与第一触控电极111电连接,另一部分(两条或者更多条)与第二触控电极112电连接。

示例性的,如图2B所示,与第二触控电极112电连接的第二类触控引线120b,经由第二显示区AA2中,沿第一方向X1位于第一显示区AA1两侧的部分、以及沿第二方向Y1位于第一显示区AA1一侧、且靠近扇出区BB的部分延伸至扇出区BB。
在一些示例中,触控引线120的材质可以为透明氧化铟锡(英文全称:Indium Tin Oxide,英文简称:ITO)或者透明氧化铟锌(英文全称:Indium Zinc Oxide,英文简称:IZO)等,减小了触控引线120对第二显示区AA2内显示的图像信息造成的影响。
在一些示例中,如图2A所示,触控显示面板200还包括连接区230,连接区230位于周边区CC内。示例性的,连接区230位于扇出区BB远离显示区AA的一侧。连接区230内设置有多个连接引脚(图中未示出),触控引线120延伸至连接区230,且与连接区230内的连接引脚电连接。
示例性的,触控显示面板200外部的柔性电路板(英文全称:Flexible Printed Circuit,英文简称:FPC,图中未示出)能够与连接区230内的 多个连接引脚绑定连接。柔性电路板上安装有触控芯片(英文全称:Integrated Circuit,英文简称:IC,图中未示出)。触控IC能够通过柔性电路板和触控引线120,获取到多个触控电极110的电容值,也即是能够获取到多个电容单元113的电容值,使得触控IC能够根据多个电容单元113的电容值确定触碰位置。示例性的,触控IC采用COF(英文全称:Chip On Film)工艺,安装在柔性电路板上。
在一些示例中,如图2A所示,触控显示面板200还包括多条数据线160,示例性的,多条数据线160的一端与多个子像素220电连接,另一端与连接区230内的连接引脚电连接。触控显示面板200外部的驱动IC(图2A中未示出)通过连接区230内的连接引脚,与多条数据线160电连接,使得驱动IC能够通过多条数据线160向子像素220输出数据信号,从而驱动子像素220发光。
在一些示例中,驱动IC采用COF工艺,安装在与连接区230绑定连接的柔性电路板上。
在一些示例中,柔性电路板远离连接区230的一端,与主控电路板电连接。
在一些示例中,如图2A和所示,触控显示面板200还具有弯折区DD,弯折区DD位于周边区CC内,示例性的,弯折区DD位于扇出区BB和连接区230之间。
可以理解地,弯折区DD能够向远离显示侧的方向弯折,从而使得连接区230能够位于显示基板210的背面(也即是远离显示侧的一面),避免了连接区230、以及与连接区230绑定连接的柔性电路板等占用显示基板210的显示侧的空间,减小触控显示面板200下边框(靠近扇出区BB一侧边框)的宽度,提高触控显示面板200的视觉效果。
图2C为根据又一些实施例的触控显示面板的结构图。
由上述可知,在一些示例中,驱动IC采用COF工艺,安装在与连接区230绑定连接的柔性电路板上。在另一些示例中,如图2C所示,触控显示面板200还包括绑定区240。绑定区240位于周边区CC内,且位于连接区230和弯折区DD之间。驱动IC(参见图2C中242所示)采用COP(英文全称:Chip On Panel)工艺,绑定连接在显示基板210的位于绑定区240内的衬底211上。
示例性的,多条数据线160与绑定区240电连接,使得驱动IC能够通过多条数据线160向子像素220输出数据信号,从而驱动子像素220 发光。
示例性的,如图2A所示,多条数据线160在扇出区BB内靠近并聚拢,也即是,在扇出区BB内,多条数据线160中的至少两条数据线160之间的距离逐渐减小。
在一些示例中,如图2A所示,在扇出区BB内,多条触控引线120位于多条数据线160的两侧。如此设置,缩短了触控引线120的长度,减小触控引线120的电阻,降低触控引线120的负载,提高信号在触控引线120上的传输可靠性。
由上述可知,本公开的实施例中,将触控电极110设置在第一显示区AA1,并且设置触控引线120经由第二显示区AA2延伸至扇出区BB,避免了触控引线120占用触控显示面板200的周边区CC的空间,从而能够减小周边区CC的宽度,利于触控显示面板200的实现窄边框,提高触控显示面板200的视觉效果。
并且,设置触控引线120经由第二显示区AA2延伸至扇出区BB,触控电极110位于第一显示区AA1,减小了触控引线120与触控电极110之间的相互影响,在使得触控显示面板200实现窄边框的基础上,提高了触控功能层100的触控性能,从而提高了触控显示面板200的使用性能。
此外,由于触控引线120较细,故而将触控引线120设置在显示区AA2内,对于显示区AA2内显示的图像信息造成的影响较小,降低了触控引线120被肉眼察觉到的风险,提高触控显示面板200的显示性能。
并且,设置触控引线120经由第二显示区AA2延伸至扇出区BB,工艺简单,易于实现,提高触控显示面板200的生产效率,降低触控显示面板200成本。
图2D为根据一些实施例的触控有效区与显示区之间的位置关系图。图2E为根据又一些实施例的触控显示面板的结构图。
由上述可知,多个触控电极110包括多个第一触控电极111和多个第二触控电极112。多个第一触控电极111沿第一方向X1间隔排布,且均沿与第一方向X1交叉的第二方向Y1延伸。多个第二触控电极112沿第二方向Y1间隔排布,且均沿第一方向X1延伸。多个第二触控电极112与多个第一触控电极111彼此交叉且相互绝缘,以在各个交叉位置处构成电容单元113。
示例性的,如图1C所示,多个触控电极110能够构成多个电容单元113,触控电极110整体所在的最小封闭图形区域的边缘,与显示区AA 的边缘相重合。
可以理解地,如图1C所示,由于电容单元113为正方形或者近似正方形,并且触控电极110整体所在的最小封闭图形区域的边缘,与显示区AA的边缘相重合,这样一来,当显示区AA的形状为长方形、圆形或者其他不规则形状时,会导致边缘处的部分触控电极110不能够形成完整的电容单元113。
也即是,如图2D所示,多个电容单元113整体所在的最小封闭图形区域的边缘,与显示区AA的边缘之间存在间隔。需要说明的是,图2D中示出的为多个电容单元113整体所在的最小封闭图形区域的一部分,本公开的实施例对电容单元113的数量不做进一步限定。
可以理解地,如图2D所示,当人手指或者触控笔等触碰到多个电容单元113整体所在的最小封闭图形区域时,触控显示面板200能够获取到触碰位置。而当人手指或者触控笔等触碰到显示区AA之内、多个电容单元113整体所在的最小封闭图形区域之外时,触控显示面板200无法准确地获取到触碰位置,甚至无法获取到触碰位置。
示例性的,如图2D所示,可以将多个电容单元113整体所在的最小封闭图形区域称为触控有效区(如图2D中区域AA3所示),将位于显示区AA和触控有效区之间的区域称为触控无效(英文名称:Dummy)区(如图2D中区域AA4所示)。
示例性的,如图2E所示,触控无效区位于触控有效区和周边区CC之间,并且,触控有效区和触控无效区内均设置有触控电极110,触控引线120位于周边区CC内。这样一来,会导致周边区CC的宽度增大,从而导致触控显示面板200的边框宽度增大。示例性的,可以将位于触控无效区内的触控电极110称为Dummy块。
由上述可知,在一些示例中,如图2B所示,显示区AA包括第一显示区AA1和第二显示区AA2,并且第二显示区AA2围设于第一显示区AA1。
在一些实施例中,如图2B所示,多个电容单元113整体所在的最小封闭图形区域为第一显示区AA1。
可以理解地,当人手指或者触控笔等触碰第一显示区AA1时,触控显示面板200能够获取到触碰位置,也即是第一显示区AA1为触控有效区。示例性的,如图2B所示,触控电极110的边缘与第一显示区AA1的边缘相重合。
第二显示区AA2围设于第一显示区AA1,并且第二显示区AA2内设置有触控引线。可以理解地,由于触控电极110的边缘与第一显示区AA1的边 缘相重合,第二显示区AA2内并没有设置触控电极110,使得第二显示区AA2无法获取到触碰位置,也即是第二显示区AA2为触控无效区。
也即是,本公开的实施例中,在触控无效区内不设置触控电极110,而是设置多条触控引线120经由触控无效区(也即是第二显示区AA2)延伸至扇出区BB,从而能够在不影响触控显示面板200的触控性能的基础上,实现触控显示面板200的窄边框,提高触控显示面板200的可靠性。
并且,设置触控电极110的边缘与第一显示区AA1的边缘相重合,也即是触控电极110的边缘与触控有效区的边缘相重合,避免了触控电极110延伸至触控无效区,简化了触控功能层100的结构,降低触控功能层100的成本。
图2F为根据一些实施例的触控功能层的局部结构图。
由上述可知,多个电容单元113能够与多条触控引线120电连接。示例性的,如图2F所示,电容单元113包括电容单元113a和电容单元113b,电容单元113a和电容单元113b沿第二方向Y1相邻设置。需要说明的是,电容单元113a和电容单元113b仅用于区分两个沿第二方向Y1相邻设置的电容单元113,不对电容单元113做进一步限定。
如图2F所示,触控引线120包括触控引线120c和触控引线120d。触控引线120c与电容单元113a电连接,触控引线120d与电容单元113b电连接。需要说明的是,触控引线120c和触控引线120d仅用于区分与电容单元113a和电容单元113b电连接的两条触控引线120,不对触控引线120做进一步限定。
示例性的,如图2F所示,由于电容单元113a和电容单元113b沿第二方向Y1相邻设置,使得触控引线120c位于显示区AA内的部位长度,大于触控引线120d位于显示区AA内的部位的长度。
也即是,多个电容单元113阵列排布,会导致多条触控引线120位于显示区AA内的长度不一致,影响了多条触控引线120之间的负载一致性,从而影响了触控功能层100的触控性能
在一些示例中,如图2F所示,沿远离显示区AA的方向,多条触控引线120位于显示区AA内的部位的长度逐渐增大。在另一些示例中,沿远离显示区AA的方向,多条触控引线120位于显示区AA内的部位的长度逐渐减小。
图2G为根据又一些实施例的触控显示面板的结构图。图2H为根据又一些实施例的触控显示面板的结构图。
基于此,在本公开的一些实施例中,如图2G和图2H所示,多条触控引线120中,两条触控引线120位于显示区AA内的部位的长度差值的绝对值的取值范围为0mm~4mm。
可以理解地,触控引线120位于显示区AA内的部位的长度,为触控引线120位于第一显示区AA1内的部位的长度,与该条触控引线120位于第二显示区AA2内的部位的长度之和。
在一些示例中,任意两条触控引线120位于显示区AA(包括第一显示区AA1和第二显示区AA2)内的部位的长度差值的绝对值的取值范围为0mm~4mm。
如此设置,提高了多条触控引线120位于显示区AA内的部位的长度一致性,一方面,提高多条触控引线120的电阻一致性,另一方面,还能够提高多条触控引线120与其他膜层(例如显示基板210的阴极层CTD或者位于第一显示区AA1内的触控电极110等)之间形成的寄生电容的一致性,使得多条触控引线120能够实现等电容布线。这样一来,就能够提高多条触控引线120之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
在一些示例中,任意两条触控引线120位于显示区AA内的部位的长度差值的绝对值的取值可以为0mm、1mm、2mm或者3mm等。
由上述可知,触控引线120远离触控电极110的一端延伸至扇出区BB。在一些示例中,任意两条触控引线120位于扇出区BB内的部位的长度基本相等。如此设置,在提高多条触控引线120位于显示区AA内的部位的长度一致性的基础上,提高了多条触控引线120位于扇出区BB内的部位的长度一致性,从而提高多条触控引线120整体(包括位于显示区AA内的部位和位于扇出区BB内的部位)的长度一致性,进一步提高触控功能层100的触控性能。
在一些实施例中,如图2G和图2H所示,多条触控引线120中,至少两条触控引线120位于显示区AA内的部位的长度基本相等。
示例性的,至少两条触控引线120位于显示区AA内的部位的长度差值的绝对值的取值范围可以为0mm~3mm、0mm~2mm或者范围为0mm~1mm等。
示例性的,至少两条触控引线120位于显示区AA内的部位的长度差值的绝对值可以为0.5mm、1.2mm、1.8mm或者2.2mm等。
在一些示例中,任意两条触控引线120位于显示区AA内的部位的长 度基本相等。
如此设置,提高了多条触控引线120位于显示区AA内的部位的长度一致性,一方面,提高多条触控引线120的电阻一致性,另一方面,还能够提高多条触控引线120与其他膜层(例如显示基板210的阴极层CTD或者位于第一显示区AA1内的触控电极110等)之间形成的寄生电容的一致性,使得多条触控引线120能够实现等电容布线。这样一来,就能够提高多条触控引线120之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
图3A为根据又一些实施例的触控显示面板的结构图。
在一些实施例中,如图3A所示,触控引线120包括第一引出线121和第二引出线122。第一引出线121的一端与位于第一显示区AA1的触控电极110电连接。第一引出线121的另一端延伸至第二显示区AA2。第二引出线122的一端与第一引出线121远离触控电极110的一端电连接,另一端延伸至第二显示区AA2与扇出区BB的交界处。并且,第二引出线122沿第一显示区AA的边缘的延伸方向延伸。
由上述可知,在一些示例中,第二显示区AA2靠近扇出区BB一侧的边缘,与扇出区BB靠近第二显示区AA2一侧的边缘相重合。在一些示例中,第二引出线122远离第一引出线121的一端可以延伸至第二显示区AA2与扇出区BB相重合的边缘位置。在另一些示例中,第二引出线122远离第一引出线121的一端也可以和第二显示区AA2与扇出区BB相重合的边缘之间具有缝隙。
可以理解地,第一引出线121的一端位于第一显示区AA1,使得第一引出线121能够与位于第一显示区AA1的触控电极110电连接。第一引出线121的另一端从第一显示区AA1延伸至第二显示区AA2。第二引出线122一端与第一引出线121电连接,另一端延伸至第二显示区AA2与扇出区BB的交界处,也即是,第一引出线121和第二引出线122均位于显示区AA(包括第一显示区AA1和第二显示区AA2)。
在一些示例中,如图3A所示,沿远离显示区AA的方向,多条第二引出线122的长度逐渐增大。在另一些示例中,沿远离显示区AA的方向,多条第二引出线122的长度逐渐减小。
在一些示例中,如图3A所示,触控引线120还包括第三引出线127。第三引出线127位于扇出区BB,且与第二引出线122远离第一引出线121的一端电连接。这样一来,使得电信号能够经由第一引出线121、第二引出线122 和第三引出线127,在扇出区BB和第一显示区AA1之间传输。
示例性的,如图3A所示,第二引出线122沿第一显示区AA1的边缘的延伸方向延伸。也即是,第二引出线122的延伸方向,与第一显示区AA1的边缘的延伸方向相平行。如此设置,能够提高多条第二引出线122的排布规整性,一方面,能够减少多条第二引出线122的占用空间,降低多条第二引出线122被肉眼察觉到的风险,提高触控显示面板200的显示可靠性。另一方面,还能够缩短第二引出线122的距离,从而减小触控引线120的负载,提高信号的传输可靠性。
在一些示例中,任一条触控引线120中,第一引出线121和第二引出线122的长度之和为第一设定长度值。如图3A所示,多条触控引线120中,第一长度值最长的触控引线120为第二触控引线124,其余的触控引线120为第一触控引线123。
在一些示例中,第二触控引线124的数量为多条,多条第二触控引线124的第一长度值基本相等。第一触控引线123的数量为多条,多条第一触控引线123的第一长度值可以相等,也可以不相等。可以理解地,任一条第一触控引线123的第一长度值,小于第二触控引线124的第一长度值。
在一些示例中,如图3A所示,第一触控引线123还包括第一补偿线125。第一补偿线125位于第二显示区AA2,且与第一触控引线123中的第一引出线121和/或第二引出线122电连接。
在一些示例中,第一补偿线125与第一触控引线123中的第一引出线121电连接。在另一些示例中,第一补偿线125与第一触控引线123中的第二引出线122电连接。在又一些示例中,第一补偿线125与第一触控引线123中,第一引出线121和第二引出线122电连接的端点电连接,使得第一补偿线125能够与第一触控引线123中的第一引出线121和第二引出线122电连接。
可以理解地,设置第一补偿线125与第一触控引线123中的第一引出线121和/或第二引出线122电连接,使得第一触控引线123中的第一引出线121和第二引出线122上的电信号,能够传输至第一补偿线125。
由上述可知,第一触控引线123的第一长度值,小于第二触控引线124的第一长度值。故而,设置第一补偿线125与第一触控引线123中的第一引出线121和/或第二引出线122电连接,使得第一补偿线125能够对第一触控引线123起到补偿的作用,减小第一触控引线123的第一长度值与第一补偿线125的长度之和,与第二触控引线124的第一长度值之间的差值的绝对值,也即是能够减小多条触控引线120位于显示区AA内的部位的长度之间差值 的绝对值。
如此设置,提高了多条触控引线120位于显示区AA内的部位的长度一致性,一方面,提高多条触控引线120的电阻一致性,另一方面,还能够提高多条触控引线120与其他膜层(例如显示基板210的阴极层CTD或者位于第一显示区AA1内的触控电极110等)之间形成的寄生电容的一致性,使得多条触控引线120能够实现等电容布线。这样一来,就能够提高多条触控引线120之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
在一些示例中,第一触控引线123中,第二引出线122和第一补偿线125的长度之和为第二设定长度值。两条第一触控引线123的第二设定长度值的差值的绝对值的取值范围为0mm~4mm。
在一些示例中,任意两条第一触控引线123的第二设定长度值的差值的绝对值的取值范围为0mm~4mm。
可以理解地,由于第一触控引线123中的第二引出线122和第一补偿线125均位于显示区AA(第二显示区AA2)内,故而,设置两条第一触控引线123的第二设定长度值的差值的绝对值的取值范围为0mm~4mm,能够提高多条第一触控引线123位于显示区AA(第二显示区AA2)内的部位的长度一致性。
这样一来,一方面,能够提高多条第一触控引线123之间的电阻一致性,减小多条第一触控引线123之间的电阻差异。另一方面,还能够提高多条第一触控引线123与其他膜层(例如显示基板210的阴极层CTD或者位于第一显示区AA1内的触控电极110等)之间形成的寄生电容的一致性,使得多条第一触控引线123能够实现等电容布线。这样一来,就能够提高多条第一触控引线123之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
示例性的,任意两条第一触控引线123的第二设定长度值的差值的绝对值的取值可以为0mm、1mm、2mm或者3mm等。
由上述可知,触控引线120(包括第一触控引线123和第二触控引线123)包括第一引出线121。在一些示例中,多条触控引线120(包括第一触控引线123和第二触控引线123)的第一引出线121的长度基本相等,提高多条触控引线120(包括第一触控引线123和第二触控引线123)位于显示区AA内的部位的长度一致性,从而提高多条触控引线120(包括第一触控引线123和第二触控引线123)之间的负载一致性,从而提高触控功能层100的触控性能。
在一些示例中,任一条第一触控引线123的第二设定长度值(也即是第一触控引线123的第二引出线122和第一补偿线125的长度之和),与第二触控引线124的第二引出线122的长度基本相等。
如此设置,能够提高多条触控引线120(包括第一触控引线123和第二触控引线123)位于显示区AA内的部位的长度一致性,从而提高多条触控引线120(包括第一触控引线123和第二触控引线123)之间的负载一致性,从而提高触控功能层100的触控性能。
在一些实施例中,如图3A所示,至少两条第一触控引线123的第二设定长度值基本相等。
示例性的,至少两条第一触控引线123的第二设定长度值的绝对值的取值范围可以为0mm~3mm、0mm~2mm或者范围为0mm~1mm等。
示例性的,至少两条第一触控引线123的第二设定长度值差值的绝对值可以为0.5mm、1.2mm、1.8mm或者2.2mm等。
在一些示例中,任意两条第一触控引线123的第二设定长度值基本相等。
如此设置,一方面,提高多条第一触控引线123之间的电阻一致性,减小多条第一触控引线123之间的电阻差异。另一方面,还能够提高多条第一触控引线123与其他膜层(例如显示基板210的阴极层CTD或者位于第一显示区AA1内的触控电极110)之间形成的寄生电容的一致性,使得多条第一触控引线123能够实现等电容布线。这样一来,就能够提高多条第一触控引线123之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
在一些实施例中,如图3A所示,第一触控引线123包括第一条第一触控引线123a和第二条第一触控引线123b,第一条第一触控引线123a的第一设定长度值,大于第二条第一触控引线123b的第一设定长度值。也即是,第一条第一触控引线123a中的第一引出线121和第二引出线122的长度之和,大于第二条第一触控引线124b中的第一引出线121和第二引出线122的长度之和。
第一补偿线125包括第一条第一补偿线125a和第二条第一补偿线125b,第一条第一补偿线第一补偿线125a的长度,小于第二条第一补偿线125b的长度。如图3A所示,第一条第一补偿线125a与第一条第一触控引线123a电连接,第二条第一补偿线125b与第二条第一触控引线123b电连接。
也即是,如图3A所示,长度较短的第一补偿线125(第一条第一补偿线125a),与第一设定长度值较长的第一触控引线123(第一条第一触控引线 123a)电连接,长度较长的第一补偿线125(第一条第一补偿线125b),与第一设定长度值较短的第一触控引线123(第一条第一触控引线123b)电连接。
这样一来,使得长度较短的第一补偿线125(第一条第一补偿线125a),能够对第一设定长度值较长的第一触控引线123(第一条第一触控引线123a)进行补偿,而长度较长的第一补偿线125(第一条第一补偿线125b),能够对第一设定长度值较短的第一触控引线123(第一条第一触控引线123b)进行补偿,提高多条第一触控引线123之间的长度一致性,从而提高多条第一触控引线123之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。
在一些实施例中,如图3A所示,沿远离显示区AA的方向,多条触控引线120的第一设定长度值逐渐增大。
由上述可知,第二触控引线124的第一设定长度值,大于任一条第一触控引线123的第一设定长度值。这样一来,设置沿远离显示区AA的方向,多条触控引线120的第一设定长度值逐渐增大,使得第二触控引线124相对于任一条第一触控引线123远离显示区AA。
并且,由上述可知,如图3A所示,长度较短的第一补偿线125(第一条第一补偿线125a),与第一设定长度值较长的第一触控引线123(第一条第一触控引线123a)电连接,长度较长的第一补偿线125(第一条第一补偿线125b),与第一设定长度值较短的第一触控引线123(第一条第一触控引线123b)电连接。这样一来,设置沿远离显示区AA的方向,多条触控引线120的第一设定长度值逐渐增大,使得沿远离显示区AA的方向,多条第一补偿线125的长度逐渐减小。
在一些示例中,沿远离显示区AA的方向,多条触控引线120的第一设定长度值呈等差数列逐渐增大。也即是,沿远离显示区AA的方向,任意相邻的两条触控引线120的第一设定长度值的差值的绝对值相等。在另一些示例中,沿远离显示区AA的方向,任意相邻的两条触控引线120的第一设定长度值的差值的绝对值也可以不相等。
可以理解地,设置沿远离显示区AA的方向,多条触控引线120的第一设定长度值逐渐增大,能够避免多条触控引线120在延伸时产生相互干扰,提高多条触控引线120的布线便捷性,从而提高触控显示面板200的加工便捷性。
在一些实施例中,如图3A所示,第一补偿线125在显示基板210上的正 投影的至少部分,位于第一引出线121和/或第二引出线122在显示基板210上的正投影的范围之外。
可以理解地,第一补偿线125在显示基板210上的正投影的至少部分,位于第一触控引线123的第一引出线121和/或第二引出线122在显示基板210上的正投影的范围之外。并且,第一补偿线125在显示基板210上的正投影的至少部分,还位于第二触控引线124的第一引出线121和/或第二引出线122在显示基板210上的正投影的范围之外。

由上述可知,如图3D所示,第二引出线122远离第一引出线121的一端,延伸至第二显示区AA2和扇出区BB的交界处。故而,设置第一补偿线125的一端与第一连接端Q1连接,另一端向远离第二引出线122的方向延伸,使得第一补偿线125远离第一连接端Q1的一端,能够向远离扇出区BB的方向延伸。
如此设置,一方面,能够减小第一补偿线125在显示基板210上的正投影,与第一引出线121和第二引出线122在显示基板210上的交叠面积,从而减小第一补偿线125与第一引出线121和第二引出线122之间产生的寄生电容,提高多条第一触控引线123之间的电容一致性,使得多条第一触控引线123能够实现等电容布线,提高多条第一触控引线123之间的负载一致性,提高触控功能层100的触控性能,从而提高触控显示面板200的使用性能。

在一些示例中,如图4A和图4B所示,第一导电层130相对于第二导电层140远离衬底211。这样一来,设置第一补偿线125(或者第一补偿线125中的多条第一子补偿线1251)、第一引出线121和第二引出线122均位于第一导电层130,能够增大多条第一补偿线125(或者第一补偿线125中的多条第一子补偿线1251)、第一引出线121和第二引出线122与显示基板210的导电膜层216(例如阴极层CTD)之间的距离,减小多条第一补偿线125(或者第一补偿线125中的多条第一子补偿线1251)、第一引出线121和第二引出线122与显示基板210的导电膜层216之间形成的寄生电容,从而减小触控引线120的负载,提高触控功能层100的触控性能,提高触控显示面板200的性能。
