图1为根据一些实施例的显示装置的俯视图。
参见图1,本公开的一些实施例所提供的显示装置100,该显示装置100包括显示面板200。
显示装置100可以为液晶显示装置(Liquid Crystal Display,简称LCD);该显示装置100也可以为电致发光显示装置或光致发光显示装置。在显示装置100为电致发光显示装置的情况下,电致发光显示装置可以为有机电致发光显示装置(Organic Light-Emitting Diode,简称OLED)或量子点电致发光显示装置(Quantum Dot Light Emitting Diodes,简称QLED)。在显示装置100为光致发光显示装置的情况下,光致发光显示装置可以为量子点光致发光显示装置。
上述显示装置100可以是显示不论运动(例如,视频)还是固定(例如,静止图像)的且不论文字还是的图像的任何装置。更明确地说,预期所述实施例可实施在多种电子装置中或与多种电子装置关联,所述多种电子装置例如(但不限于)移动电话、无线装置、个人数据助理(PDA)、手持式或便携式计算机、GPS接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如,里程表显示器等)、导航仪、座舱控制器和/或显示器、相机视图的显示器(例如,车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构(例如,对于一件珠宝的图像的显示器)等。
本公开的以下各实施例以显示装置100为电致发光显示装置为例进行说明,在此情况下,显示面板200即为电致发光显示面板。
图2为图1中的显示面板沿剖面线A-A'的剖视图。
在一些实施例中,如图2所示,显示面板200包括显示基板1和触控结构2,触控结构2设置于显示基板1的出光侧E。
其中,如图2所示,显示基板1包括衬底基板10,以及设置于衬底基板10上的多个子像素P。每个子像素P包括设置于衬底基板10上的像素驱动电路D和发光器件L,像素驱动电路D包括多个薄膜晶体管TFT(英文全称:Thin Film Transistor)。发光器件L包括阳极L1、发光功能层L2以及阴极L3,阳极L1和多个薄膜晶体管TFT中作为驱动晶体管的薄膜晶体管TFT的漏极(或源极)电连接。
如图2所示,显示基板1还包括设置在薄膜晶体管TFT和阳极L1之间的平坦层11。
如图2所示,显示基板1还包括像素界定层12,像素界定层12包括多个开口区120,一个发光器件L设置在一个开口区120中。在一些实施例中,发光功能层L2包括发光层。在另一些实施例中,发光功能层L2除包括发光层外,还包括电子传输层(Election Transporting Layer,简称ETL)、电子注入层(Election Injection Layer,简称EIL)、空穴传输层(Hole Transporting Layer,简称HTL)以及空穴注入层(Hole Injection Layer,简称HIL)中的一层或多层。
上述显示面板200可以是顶发射型显示面板,在此情况下,靠近衬底基板10的阳极L1是不透明的,远离衬底基板10的阴极L3是透明或半透明的;显示面板200也可以是底发射型显示面板,在此情况下,靠近衬底基板10的阳极L1是透明或半透明的,远离衬底基板10的阴极L3是不透明的;显示面板200也可以为双面发光型显示面板,在此情况下,靠近衬底基板10的阳极L1和远离衬底基板10的阴极L3均是透明或半透明的。
在一些实施例中,如图2所示,显示基板1还包括设置于发光器件L远离衬底基板10一侧的薄膜封装层13。
示例性地,薄膜封装层13包括第一无机阻隔层131、有机阻隔层132和第二无机阻隔层133,第一无机阻隔层131、有机阻隔层132和第二无机阻隔层133依次层叠设置于发光器件L远离衬底基板10的一侧。其中,第一无机阻隔层131和第二无机阻隔层133具有阻隔水汽和氧气的作用,而有机阻隔层132具有一定的柔性和吸收水汽的作用等,以使所形成的薄膜封装层13具有良好的封装性能。
在一些实施例中,如图2所示,采用On-Cell技术的结构设计,触控结构2直接设置在薄膜封装层13上,即,触控结构10与薄膜封装层13之间不设置其它膜层,有利于减小显示面板200的厚度,以实现显示面板200的轻薄化。
图3为根据一些实施例的一种显示面板的俯视图;图4为图3中的显示面板在拐角区的局部放大图。
参见图3,显示面板200包括触控结构2,触控结构2具有触控区域TA,触控区域TA包括主触控区A1和拐角区A2,拐角区A2位于主触控区A1的周围。
参见图3和图4,触控结构2包括多个第一触控单元21和多个第二触控单元22,其中,多个第一触控单元21沿第一方向X延伸,一个第一触控单元21包括多个第一触控电极210和多个第一连接部211,第一触控电极210和第一连接部211沿第一方向X交替设置,即,一个第一连接部211电连接 相邻两个第一触控电极210。
继续参见图3和图4,多个第二触控单元22沿第二方向Y延伸,一个第二触控单元22包括多个第二触控电极220和多个第二连接部221,第二触控电极220和第二连接部221沿第二方向Y交替设置,即,一个第二连接部221电连接相邻两个第二触控电极220。
需要说明的是,第一触控电极210和第二触控电极220中的一者为TX(触控驱动电极),另一者为RX(触控感应电极)。相邻的第一触控电极210与第二触控电极220之间的侧面正对,在第一触控电极210和第二触控电极220上传输电信号的情况下,相邻的第一触控电极210与第二触控电极220之间会产生互容,在手指触摸显示面板200的过程中,手指会带走触控电极上的电荷,使触摸位置处的触控电极之间的互容值变化,显示面板200中的触控IC可检测到触控电极之间的互容值变化,以识别手指的触摸位置,从而实现显示面板200的触控功能。
并且,上述的第一方向X和第二方向Y相交叉,例如,第一方向X与第二方向Y相垂直。
本公开的发明人经研究发现,上述显示面板200采用圆角设计,即显示面板200的位于拐角区A2的边缘为弧形设计。相较于位于主触控区A1的触控电极(第一触控电极210和第二触控电极220)的图案,位于拐角区A2的部分触控电极(例如,靠近拐角区A2的边缘的触控电极210a和触控电极220a)的图案不完整,并且,这部分触控电极靠近拐角区A2的边缘的一侧不连接触控电极,导致位于拐角区A2的部分触控电极之间的正对面积减小,使位于拐角区A2的部分触控电极之间的互容值,小于位于主触控区A1的触控电极之间的互容值,导致显示面板200的拐角区A2的触控性能,相比于主触控区A1的触控性能较差。
为解决上述问题,本公开的一些实施例提供了另一种显示面板,图5为根据一些实施例的另一种显示面板的俯视图;图6A为图5中的显示面板在M处的局部放大图;图6B为图6A中的显示面板沿剖面线A-A'的剖视图;图6C为根据一些实施例的又一种显示面板在M处的局部放大图;图6D为图6C中的显示面板沿剖面线B-B'的剖视图;图7A为图5中的显示面板在拐角区的局部放大图;图7B为图7A中的显示面板沿剖面线C-C'的剖视图;图7C为根据一些实施例的又一种显示面板在拐角区的局部放大图;图7D为图7C中的显示面板沿剖面线D-D'的剖视图。
参见图5,显示面板200包括触控结构2,触控结构2具有触控区域TA, 触控区域TA包括主触控区A1和拐角区A2。
参见图5和图6A,触控结构2包括多个第一触控单元21和多个第二触控单元22,其中,多个第一触控单元21沿第一方向X延伸,一个第一触控单元21包括多个第一触控电极210和多个第一连接部211,第一触控电极210和第一连接部211沿第一方向X交替设置,即,一个第一连接部211电连接相邻两个第一触控电极210。
继续参见图5和图6A,多个第二触控单元22沿第二方向Y延伸,一个第二触控单元22包括多个第二触控电极220和多个第二连接部221,第二触控电极220和第二连接部221沿第二方向Y交替设置,即,一个第二连接部221电连接相邻两个第二触控电极220。
下面从膜层结构的角度去描述,连接部与相邻两个触控电极的连接方式。
参见图6B,触控结构2包括层叠设置的第一导电层2a、绝缘层2b和第二导电层2c,绝缘层2b位于第一导电层2a与第二导电层2c之间。其中,绝缘层2b中设有多个过孔H。
需要说明的是,第一导电层2a可以位于第二导电层2c靠近或远离显示基板1的一侧,本公开的以下实施例均以第一导电层2a位于第二导电层2c靠近显示基板1的一侧为例进行说明。
继续参见图6B,第一触控电极210、第二触控电极220和第一连接部211位于第一导电层2a中,第二连接部221位于第二导电层2c中。沿第一方向X,相邻两个第一触控电极210通过第一连接部211直接电连接。沿第二方向Y,第二连接部221穿过绝缘层2b中不同过孔H与相邻两个第二触控电极220电连接。
或者,参考图6C和图6D,第一触控电极210、第二触控电极220和第二连接部221位于第一导电层2a中,第一连接部211位于第二导电层2c中。沿第二方向Y,相邻两个第二触控电极220通过第二连接部221直接电连接。沿第一方向X,第一连接部211穿过绝缘层2c中不同过孔H与相邻两个第一触控电极210电连接。
此外,参见图6B和图6D,触控结构2还包括设置于第二导电层2c远离显示基板1一侧的保护层2d,起到保护和绝缘的作用。
上述触控结构2的结构设计所采用的技术为FMLOC(Flexible Multi-Layer On Cell)技术,即采用两个导电层形成第一触控电极210、第二触控电极220、第一连接部211和第二连接部221。
如图6A和图7A所示,第一连接部211在参考面上的正投影与第二连接 部221在参考面上的正投影相交叉,相交叉的第一连接部211与第二连接部221形成一个连接单元20。多个第一连接部211和多个第二连接部221形成的多个连接单元20中的至少一个为调整连接单元20a,该调整连接单元20a位于拐角区A2内。
需要说明的是,上述“参考面”可以是显示基板1所在的平面,可以是触控结构2所在的平面,也可以是图5中第一方向X与第二方向Y所在的平面。
结合图5和图7A,调整连接单元20a的第一连接部211所在的第一触控单元21中,经过位于主触控区A1的至少两个第一触控电极210的中心的直线为第一参考线L1。调整连接单元20a的第二连接部221所在的第二触控单元22中,经过位于主触控区A1的至少两个第二触控电极220的中心的直线为第二参考线L2,第一参考线L1与第二参考线L2的交点为参考点P。参考点P位于拐角区A2外,且参考点P相对于调整连接单元20a远离主触控区A1的中心C。
可以理解的是,在显示面板200不采用圆角设计的情况下,例如,显示面板200采用直角设计,那么按照触控结构2在主触控区A1的排布设计原则,“参考点P”所在的位置应该设置有连接单元20。这里,引用“参考点P”这一概念,通过描述参考点P与调整连接单元20a的相对位置关系,以便于描述调整连接单元20a的位置。
因此,参考点P位于拐角区A2外,且参考点P相对于调整连接单元20a远离主触控区A1的中心C,可以理解为,将本应该设置于参考点P处的连接单元20(因显示面板200采用圆角设计而被去除)朝靠近主触控区A1的中心C的方向挪动,得到调整连接单元20a的设计位置。
本公开的上述实施例所提供的触控结构2,将本应该设置于参考点P处的连接单元20,朝靠近主触控区A1的中心C的方向挪动,得到调整连接单元20a的设计位置。即,在拐角区A2增加调整连接单元20a,并在拐角区A2增加与调整连接单元20a电连接的触控电极,从而增加位于拐角区A2的部分触控电极之间的正对面积,以提高该部分触控电极之间的互容值,提高显示面板200的拐角区A2的触控性能。
在一些实施例中,如图5所示,多个第一触控单元21和多个第二触控单元22相互交叉,形成多个电容单元23。多个电容单元23沿第一方向X排列成多行,且沿第二方向Y排列成多列。
参见图6A和图7A,每个电容单元23包括一个连接单元20,该连接单 元20的第一连接部211连接的两个第一触控电极210中相对的部分,以及该连接单元20的第二连接部221连接的两个第二触控电极220中相对的部分。
参见图7A,调整连接单元20a所在的电容单元23为补偿电容单元230,与补偿电容单元230同行且相邻的电容单元23为第一电容单元231,与补偿电容单元230同列且相邻的电容单元23为第二电容单元232,补偿电容单元230、第一电容单元231和第二电容单元232均位于拐角区A2。
可以理解的是,参考图6A,具有完整图案的第一触控电极210(位于主触控区A1的第一触控电极210)包括两个一体设置的第一子电极210b,同样的,具有完整图案的第二触控电极220(位于主触控区A1的第二触控电极220)也包括两个一体设置的第二子电极220b。
因此,在主触控区A1内,每个电容单元23中的第一连接部211所连接的两个第一触控电极210中相对的部分为,该第一连接部211所连接的相邻两个第一子电极210b。同样的,每个电容单元23中的第二连接部221所连接的两个第二触控电极220中相对的部分为,该第二连接部221所连接的相邻两个第二子电极220b。
参考图5和图7A,在拐角区A2内,调整连接单元20a的第一连接部211所连接的两个第一触控电极210分别为第一电极E1和第二电极E2,第一电极E1相对于第二电极E2远离主触控区A1的中心C。调整连接单元20a的第二连接部221所连接的两个第二触控电极220分别为第三电极E3和第四电极E4,第三电极E3相对于第四电极E4远离主触控区A1的中心C。
示例性地,如图7A和图7B所示,第一电极E1、第二电极E2、第三电极E3、第四电极E4和调整连接单元20a中的第一连接部211设置于第一导电层2a,调整连接单元20a中的第二连接部221设置于第二导电层2c。沿第一方向X,第一电极E1与第二电极E2之间通过第一连接部211直接电连接。沿第二方向Y,第二连接部221穿过绝缘层2b中不同过孔H与第三电极E3和第四电极E4电连接。
或者,如图7C和图7D所示,第一电极E1、第二电极E2、第三电极E3、第四电极E4和调整连接单元20a中的第二连接部221设置于第一导电层2a,调整连接单元20a中的第一连接部211设置于第二导电层2c。沿第二方向Y,第三电极E3与第四电极E4之间通过第二连接部221直接电连接。沿第一方向X,第一连接部211穿过绝缘层2b中不同过孔H与第一电极E1和第二电极E2电连接。
相较于位于主触控区A1的具有完整图案的触控电极,拐角区A2中靠近 其边缘的部分触控电极不具有完整图案,例如,第一电极E1、第二电极E2、第三电极E3和第四电极E4均不具有完整图案,在此情况下,补偿电容单元230中调整连接单元20a的第一连接部211所连接的两个第一触控电极210中相对的部分,分别为第一电极E1,及第二电极E2中靠近第一电极E1的一部分。同样的,补偿电容单元230中调整连接单元20a的第二连接部221所连接的两个第二触控电极220中相对的部分,分别为第三电极E3,及第四电极E4中靠近第三电极E3的一部分。
如图7A所示,调整连接单元20a在参考面上的正投影位于补偿电容单元230在参考面上的正投影的范围内。其中,“参考面”的定义可参见前文的解释说明。
可以理解的是,若调整连接单元20a设置在补偿电容单元230与第一电容单元231的交界上,或者设置在补偿电容单元230与第二电容单元232的交界上,会使得补偿电容单元230中触控电极之间的正对面积较小,使补偿电容单元230的互容值较小。因此,调整连接单元20a在参考面上的正投影位于补偿电容单元230在参考面上的正投影的范围内,采用此设计方式,可提高补偿电容单元230中触控电极之间的正对面积,从而提高补偿电容单元230的互容值,有利于提高显示面板200的拐角区A2的触控性能。
在一些实施例中,如图6A和图7A所示,第一电容单元231的面积,大于补偿电容单元230的面积,小于位于主触控区A1的一个电容单元23的面积。第二电容单元232的面积,大于补偿电容单元230的面积,小于位于主触控区A1的一个电容单元23的面积。
可以理解的是,显示面板200采用圆角设计,相较于位于主触控区A1的电容单元23,补偿电容单元230、第一电容单元231和第二电容单元232均位于拐角区A2,三者中均有部分触控电极的图案缺失,其中,补偿电容单元230中触控电极的图案缺失面积较大。
在一些实施例中,如图7A所示,补偿电容单元230被第三参考线L3划分为第一子电容单元230a和第二子电容单元230b,第一子电容单元230a相对于第二子电容单元230b靠近第一电容单元231。
需要说明的是,第三参考线L3为,过调整连接单元20a的中心,且沿第二方向Y延伸的直线。
设定第一子电容单元230a的面积与第二子电容单元230b的面积的比值为第一比值;第一电容单元231的面积与位于主触控区A1的电容单元23的面积之差,与,第二电容单元232的面积与位于主触控区A1的电容单元23 的面积之差的比值为第二比值,且第一比值与第二比值大致相等。
可以理解的是,补偿电容单元230与第一电容单元231共用第二电极E2,且补偿电容单元230中的第一子电容单元230a更靠近第一电容单元231。由于第一电容单元231的图案相较位于主触控区A1的电容单元23的图案缺失,因此,第一子电容单元230a的互容值可以补偿给第一电容单元231,以补偿因第一电容单元231的图案缺失而损失的互容值。
同理,补偿电容单元230与第二电容单元232共用第四电极E4,且补偿电容单元230中的第二子电容单元230b更靠近第二电容单元232。由于第二电容单元232的图案相较位于主触控区A1的电容单元23的图案缺失,因此,第二子电容单元230b的互容值可以补偿给第二电容单元232,以补偿因第二电容单元232的图案缺失而损失的互容值。
并且,可根据第二比值确定第一比值,即,根据第一电容单元231的面积与位于主触控区A1的电容单元23的面积之差,与,第二电容单元232的面积与位于主触控区A1的电容单元23的面积之差的比值,来确定第一子电容单元230a的面积与第二子电容单元230b的面积的比值。例如,第一电容单元231的图案相较第二电容单元232的图案缺失较多,则应设置第一子电容单元230a的面积大于第二子电容单元230b的面积。
进而,在第一子电容单元230a的面积与第二子电容单元230b的面积的比值确定的情况下,调整连接单元20a在第一方向X上的位置也得以确定。
本公开的上述实施例,第一子电容单元230a的互容值可以补偿给第一电容单元231,第二子电容单元230b的互容值可以补偿给第二电容单元232,可补偿因第一电容单元231和第二电容单元232的图案缺失而损失的互容值,提高第一电容单元231和第二电容单元232所在区域的触控性能,从而有利于提高显示面板200在拐角区A2的触控性能。
在一些实施例中,如图5和图7A所示,第一电容单元231、第二电容单元232和补偿电容单元230的互容值的和,约为位于主触控区A1的电容单元23的互容值的两倍。
可以理解的是,根据上文所述,第一子电容单元230a的互容值可以补偿给第一电容单元231,可补偿因第一电容单元231的图案缺失而损失的互容值,第一电容单元231的经补偿后的互容值应大致等于,位于主触控区A1的电容单元23的互容值。
同理,第二子电容单元230b的互容值可以补偿给第二电容单元232,可补偿因第二电容单元232的图案缺失而损失的互容值,第二电容单元232的 经补偿后的互容值应大致等于,位于主触控区A1的电容单元23的互容值。
因此,第一电容单元231、第二电容单元232和补偿电容单元230的互容值的和,约为位于主触控区A1的电容单元23的互容值的两倍。
在一些实施例中,如图5和图7A所示,显示面板200采用圆角设计,即显示面板200的位于拐角区A2的边缘为弧形设计,使得补偿电容单元230、第一电容单元231和第二电容单元232的形状,与位于主触控区A1的电容单元23的形状均不相同。
在一些实施例中,如图5和图7A所示,第一电容单元231的远离主触控区A1的中心C的边界S1、补偿电容单元230的远离主触控区A1的中心C的边界S2及第二电容单元232的远离主触控区A1的中心C的边界S3依次连接形成弧形的边界,该弧形的边界即为拐角区A2的边界。
图8为根据一些实施例的又一种显示面板的局部俯视图;图9A为图8中的显示面板在N处的一种局部放大图;图9B为图8中的显示面板在N处的另一种局部放大图。
结合图5和图8,调整连接单元20a的第一连接部211所连接的两个第一触控电极210分别为第一电极E1和第二电极E2,第一电极E1相对于第二电极E2远离主触控区A1的中心C。调整连接单元20a的第二连接部221所连接的两个第二触控电极220分别为第三电极E3和第四电极E4,第三电极E3相对于第四电极E4远离主触控区A1的中心C。
示例性地,参见图8,第二电极E2的面积,大于第一电极E1的面积,小于位于主触控区A1的第一触控电极210的面积。并且,第四电极E4的面积,大于第三电极E3的面积,小于位于主触控区A1的第二触控电极220的面积。

继续参见图8,第一电极E1与第三电极E3,及第一电极E1与第四电极E4的相互靠近的轮廓形状互补,可增加第一电极E1与第三电极E3之间的正对面积,以及第一电极E1与第四电极E4之间的正对面积,从而可提高第一电极E1与第三电极E3之间的互容值,以及第一电极E1与第四电极E4之间的互容值。
或者,参见图8,第二电极E2与第三电极E3,及第二电极E2与第四电极E4的相互靠近的轮廓形状互补,可增加第二电极E2与第三电极E3之间的 正对面积,以及第二电极E2与第四电极E4之间的正对面积,从而可提高第二电极E2与第三电极E3之间的互容值,以及第二电极E2与第四电极E4之间的互容值。
又或者,参见图8,第一电极E1与第三电极E3,及第一电极E1与第四电极E4的相互靠近的轮廓形状互补,且第二电极E2与第三电极E3,及第二电极E2与第四电极E4的相互靠近的轮廓形状互补,可增加第一电极E1与第三电极E3之间的正对面积,第一电极E1与第四电极E4之间的正对面积,第二电极E2与第三电极E3之间的正对面积,以及第二电极E2与第四电极E4之间的正对面积,从而可提高第一电极E1与第三电极E3之间的互容值,第一电极E1与第四电极E4之间的互容值,第二电极E2与第三电极E3之间的互容值,以及第二电极E2与第四电极E4之间的互容值,以提高补偿电容单元230的互容值。
在一些实施例中,如图9A所示,第一触控电极210、第二触控电极220、第一连接部211和第二连接部221均包括面状结构。
示例性地,调整连接单元20a的第一连接部211和第二连接部221、第一电极E1、第二电极E2、第三电极E3和第四电极E4均包括面状结构。
在一些实施例中,如图9B所示,第一触控电极210、第二触控电极220、第一连接部211和第二连接部221均包括金属网格结构。金属网格结构的电阻小、灵敏度较高,可提高显示面板200的触控性能。且金属网格结构的机械强度高、重量轻,有利于减小显示面板200的重量。
示例性地,调整连接单元20a的第一连接部211和第二连接部221、第一电极E1、第二电极E2、第三电极E3和第四电极E4均包括金属网格结构。
在一些实施例中,如图8和图9A所示,第一电极E1和第三电极E3的边缘均具有至少一个第一分支K1,例如,第一电极E1靠近第三电极E3的边缘具有至少一个第一分支K1,第三电极E3靠近第一电极E1的边缘具有至少一个第一分支K1。
其中,第一电极E1的至少一个第一分支K1伸入第三电极E3内,第三电极E3的至少一个第一分支K1伸入第一电极E1内。
示例性地,如图8和图9A所示,第一分支K1的形状为长条状。
通过上述设置方式,第一电极E1的第一分支K1伸入第三电极E3内,第三电极E3的第一分支K1伸入第一电极E1内,可进一步增加第一电极E1与第三电极E3之间的正对面积,从而可提高第一电极E1与第三电极E3之间的互容值。
需要说明的是,参考图8和图9A,位于主触控区A1的触控电极(第一触控电极210和/或第二触控电极220)的边缘具有至少一个第二分支K2,该第二分支K2也伸入与其相邻的触控电极内,从而可增加该触控电极与相邻的触控电极之间的正对面积,提高二者之间的互容值。
并且,相较于主触控区A1,调整连接单元20a所在的区域的排布空间较小,因此,将调整连接单元20a所连接的触控电极的第一分支K1的高度(第一分支K1沿其伸入方向U的尺寸)设置为,小于位于主触控区A1的触控电极的第二分支K2的高度(第二分支K2沿其伸入方向V的尺寸),可在有限的排布空间内设置更多的第一分支K1,以增加调整连接单元20a所连接的触控电极之间的正对面积,提高调整连接单元20a所连接的触控电极之间的互容值。
在一些实施例中,如图9A所示,第一电极E1和第四电极E4的边缘均具有至少一个凸起T,例如,第一电极E1靠近第四电极E4的边缘具有至少一个凸起T,第四电极E4靠近第一电极E1的边缘具有至少一个凸起T。第一电极E1的至少一个凸起T和第四电极E4的至少一个凸起T的形状相适配,即第一电极E1的凸起T与第四电极E4的凸起T的轮廓形状互补。
继续参见图9A,第二电极E2和第三电极E3的边缘均具有至少一个凸起T,例如,第三电极E3靠近第二电极E2的边缘具有至少一个凸起T,第二电极E2靠近第三电极E3的边缘具有至少一个凸起T。第二电极E2的至少一个凸起T和第三电极E3的至少一个凸起T的形状相适配,即第二电极E2的凸起T与第三电极E3的凸起T的轮廓形状互补。
示例性地,凸起T的形状可包括三角形、矩形、梯形、圆形和椭圆形中的至少一种,例如,图9A中示出的凸起T的形状为三角形,即第一电极E1靠近第四电极E4的边缘为锯齿状,第四电极E4靠近第一电极E1的边缘为锯齿状,第三电极E3靠近第二电极E2的边缘为锯齿状,第二电极E2靠近第三电极E3的边缘为锯齿状。
可以理解的是,参考图9A,由于第一电极E1的第一分支K1伸入第三电极E3内,且第三电极E3的第一分支K1伸入第一电极E1内,使得第一电极E1靠近第四电极E4的边缘,第四电极E4靠近第一电极E1的边缘,第三电极E3靠近第二电极E2的边缘以及第二电极E2靠近第三电极E3的边缘不具有第一分支K1的排布空间。
因此,可通过在第一电极E1靠近第四电极E4的边缘设置至少一个凸起T,在第四电极E4靠近第一电极E1的边缘设置至少一个凸起T,且凸起T的 高度(凸起T沿指定方向R1的尺寸;第一电极E1与第四电极E4的边缘沿方向S1的延伸,指定方向R1与方向S1相垂直)小于第一分支K1的高度,以在有限的排布空间内设置更多的凸起T,从而增加第一电极E1与第四电极E4之间的正对面积,提高第一电极E1与第四电极E4之间的互容值。
同理,可通过在第三电极E3靠近第二电极E2的边缘设置至少一个凸起T,在第二电极E2靠近第三电极E3的边缘设置至少一个凸起T,且凸起T的高度(凸起T沿指定方向R2的尺寸;第二电极E2与第三电极E3的边缘沿方向S2的延伸,指定方向R2与方向S2相垂直)小于第一分支K1的高度,以在有限的排布空间内设置更多的凸起T,从而增加第二电极E2与第三电极E3之间的正对面积,提高第二电极E2与第三电极E3之间的互容值。
在一些实施例中,如图9A所示,第二电极E2和第四电极E4的边缘均具有至少一个凸起T,例如,第二电极E2靠近第四电极E4的边缘具有至少一个凸起T,第四电极E4靠近第二电极E2的边缘具有至少一个凸起T。第二电极E2的至少一个凸起T和第四电极E4的至少一个凸起T的形状相适配,即第二电极E2的凸起T与第四电极E4的凸起T的轮廓形状互补。
可以理解的是,参考图9A,第二电极E2靠近第四电极E4的边缘,以及第四电极E4靠近第二电极E2的边缘的长度较短、排布空间较小,通过在第二电极E2靠近第四电极E4的边缘设置至少一个凸起T,在第四电极E4靠近第二电极E2的边缘设置至少一个凸起T,可增加第二电极E2与第四电极E4之间的正对面积,从而可提高第二电极E2与第四电极E4之间的互容值。
图10为根据一些实施例的又一种显示面板在N处的局部放大图。
参见图10,第一电极E1和第四电极E4的边缘均具有至少一个第一分支K1,例如,第一电极E1靠近第四电极E4的边缘具有至少一个第一分支K1,第四电极E4靠近第一电极E1的边缘具有至少一个第一分支K1。
其中,第一电极E1的至少一个第一分支K1伸入第四电极内E4,第四电极E4的至少一个第一分支K1伸入第一电极E1内。
通过上述设置方式,第一电极E1的第一分支K1伸入第四电极E4内,第四电极E4的第一分支K1伸入第一电极E1内,可进一步增加第一电极E1与第四电极E4之间的正对面积,从而可提高第一电极E1与第四电极E4之间的互容值。
继续参见图10,第二电极E2和第三电极E3的边缘均具有至少一个第一分支K1,例如,第二电极E2靠近第三电极E3的边缘具有至少一个第一分支K1,第三电极E3靠近第二电极E2的边缘具有至少一个第一分支K1。
其中,第二电极E2的至少一个第一分支K1伸入第三电极内,第三电极E3的至少一个第一分支K1伸入第二电极E2内。
通过上述设置方式,第三电极E3的第一分支K1伸入第二电极E2内,第二电极E2的第一分支K1伸入第三电极E3内,可进一步增加第二电极E2与第三电极E3之间的正对面积,从而可提高第二电极E2与第三电极E3之间的互容值。
示例性地,如图10所示,第一分支K1的形状为长条状。
在一些实施例中,如图10所示,第一电极E1和第三电极E3的边缘均具有至少一个凸起T,例如,第一电极E1靠近第三电极E3的边缘具有至少一个凸起T,第三电极E3靠近第一电极E1的边缘具有至少一个凸起T。第一电极E的至少一个凸起T和第三电极E3的至少一个凸起T的形状相适配,即第一电极E的凸起T与第三电极E3的凸起T的轮廓形状互补。
示例性地,凸起T的形状可包括三角形、矩形、梯形、圆形和椭圆形中的至少一种,例如,图10中示出的凸起T的形状为三角形,即第一电极E1靠近第三电极E3的边缘为锯齿状,第三电极E3靠近第一电极E1的边缘为锯齿状。
可以理解的是,参考图10,由于第一电极E1的第一分支K1伸入第四电极内E4,第四电极E4的第一分支K1伸入第一电极E1内,第三电极E3的第一分支K1伸入第二电极E2内,且第二电极E2的第一分支K1伸入第三电极内,使得第一电极E1靠近第三电极E3的边缘,以及第三电极E3靠近第一电极E1的边缘不具有第一分支K1的排布空间。
因此,可通过在第一电极E1靠近第三电极E3的边缘设置至少一个凸起T,在第三电极E3靠近第一电极E1的边缘设置至少一个凸起T,且凸起T的高度(凸起T沿指定方向R3的尺寸;第一电极E1与第三电极E3的边缘沿方向S3的延伸,指定方向R3与方向S3相垂直)小于第一分支K1的高度,以在有限的排布空间内设置更多的凸起T,从而增加第一电极E1与第三电极E3之间的正对面积,提高第一电极E1与第三电极E3之间的互容值。
在一些实施例中,如图10所示,第二电极E2和第四电极E4的边缘均具有至少一个凸起T,例如,第二电极E2靠近第四电极E4的边缘具有至少一个凸起T,第四电极E4靠近第二电极E2的边缘具有至少一个凸起T。第二电极E2的至少一个凸起T和第四电极E4的至少一个凸起T的形状相适配,即第二电极E2的凸起T与第四电极E4的凸起T的轮廓形状互补。
可以理解的是,参考图10,第二电极E2靠近第四电极E4的边缘,以及 第四电极E4靠近第二电极E2的边缘的长度较短、排布空间较小,通过在第二电极E2靠近第四电极E4的边缘设置至少一个凸起T,在第四电极E4靠近第二电极E2的边缘设置至少一个凸起T,可增加第二电极E2与第四电极E4之间的正对面积,从而可提高第二电极E2与第四电极E4之间的互容值。
图11为根据一些实施例的又一种显示面板在N处的局部放大图。
参见图11,第一电极E1、第二电极E2、第三电极E3和第四电极E4的边缘均具有至少一个凸起T,例如,第一电极E1靠近第三电极E3的边缘具有至少一个凸起T,第一电极E1靠近第四电极E4的边缘具有至少一个凸起T;第二电极E2靠近第三电极E3的边缘具有至少一个凸起T,第二电极E2靠近第四电极E4的边缘具有至少一个凸起T;第三电极E3靠近第一电极E1的边缘具有至少一个凸起T,第三电极E3靠近第二电极E2的边缘具有至少一个凸起T;第四电极E4靠近第一电极E1的边缘具有至少一个凸起T,第四电极E4靠近第二电极E2的边缘具有至少一个凸起T。
其中,第一电极E1的至少一个凸起T,和第三电极E3的至少一个凸起T的形状相适配,且和第四电极E4的至少一个凸起T的形状相适配。即,第一电极E1的凸起T与第三电极E3的凸起T的轮廓形状互补,且第一电极E1的凸起T与第四电极E4的凸起T的轮廓形状互补。
第二电极E2的至少一个凸起T,和第三电极E3的至少一个凸起T的形状相适配,且和第四电极E4的至少一个凸起T的形状相适配。即,第二电极E2的凸起T与第三电极E3的凸起T的轮廓形状互补,且第二电极E2的凸起T与第四电极E4的凸起T的轮廓形状互补。
示例性地,凸起T的形状可包括三角形、矩形、梯形、圆形和椭圆形中的至少一种,例如,图11中示出的凸起T的形状为矩形。
可以理解的是,参考图8,相较于主触控区A1,调整连接单元20a所在的区域的排布空间较小。因此,结合图8和图11,将调整连接单元20a所连接的触控电极的边缘均设置凸起T,且凸起T的高度设置为小于位于主触控区A1的触控电极的第二分支K2的高度。以第一电极E1和第四电极E4为例,凸起T的高度为凸起T沿指定方向R4的尺寸;第一电极E1与第四电极E4的边缘沿方向S4的延伸,指定方向R4与方向S4相垂直。并且,沿方向S4,第一电极E1靠近第四电极E4的边缘的凸起T的高度逐渐减小,第四电极E4靠近第一电极E1的边缘的凸起T的高度逐渐减小。
通过上述设计,可在有限的排布空间内设置更多的凸起T,以增加调整连接单元20a所连接的触控电极之间的正对面积,提高调整连接单元20a所连接 的触控电极之间的互容值。
在一些实施例中,如图8所示,至少一个第一触控电极210内设置有至少一个第一虚设电极DM1,且第一虚设电极DM1与第一触控电极210断开。
需要说明的是,第一虚设电极DM1在参考面上的正投影,位于对应的第一触控电极210在参考面上的正投影的范围内。并且,第一虚设电极DM1与第一触控电极210之间具有间隙,以保证第一虚设电极DM1与第一触控电极210断开,实现第一虚设电极DM1与第一触控电极210的绝缘。
并且,在第一触控电极210上传输电信号的情况下,第一触控电极210与显示基板1上的导电层(例如,阴极L3)之间会产生电容,这会增加电信号在第一触控电极210上的传输负载,增加显示面板200的功耗。
本公开的上述实施例,通过在第一触控电极210中设置第一虚设电极DM1,可减小第一触控电极210与显示基板1上的导电层的正对面积,从而可减小第一触控电极210与显示基板1上的导电层之间产生的电容值,降低电信号在第一触控电极210上的传输负载,以降低显示面板200的功耗。
示例性地,如图8所示,位于主触控区A1的第一触控电极210内设置有四个第一虚设电极DM1。位于拐角区A2的第一触控电极210中,第一电极E1内不设置第一虚设电极DM1,除第一电极E1外,部分第一触控电极210内设置有两个第一虚设电极DM1,部分第一触控电极210内设置有三个第一虚设电极DM1,部分第一触控电极210内设置有四个第一虚设电极DM1。
在一些实施例中,如图8所示,至少一个第二触控电极220内设置有至少一个第一虚设电极DM1,且第一虚设电极DM1与第二触控电极220断开。
需要说明的是,第一虚设电极DM1在参考面上的正投影,位于对应的第二触控电极220在参考面上的正投影的范围内。并且,第一虚设电极DM1与第二触控电极220之间具有间隙,以保证第一虚设电极DM1与第二触控电极220断开,实现第一虚设电极DM1与第二触控电极220的绝缘。
并且,在第二触控电极220上传输电信号的情况下,第二触控电极220与显示基板1上的导电层(例如,阴极L3)之间会产生电容,这会增加电信号在第二触控电极220上的传输负载,增加显示面板200的功耗。
本公开的上述实施例,通过在第二触控电极220中设置第一虚设电极DM1,可减小第二触控电极220与显示基板1上的导电层的正对面积,从而可减小第二触控电极220与显示基板1上的导电层之间产生的电容值,降低电信号在第二触控电极220上的传输负载,以降低显示面板200的功耗。
示例性地,如图8所示,位于主触控区A1的第二触控电极220内设置有 四个第一虚设电极DM1。位于拐角区A2的第二触控电极220中,第三电极E3内不设置第一虚设电极DM1,除第三电极E3外,部分第二触控电极220内设置有两个第一虚设电极DM1,部分第二触控电极220内设置有三个第一虚设电极DM1,部分第二触控电极220内设置有四个第一虚设电极DM1。
在一些实施例中,如图8所示,至少一个第一触控电极210内设置有至少一个第一虚设电极DM1,且第一虚设电极DM1与第一触控电极210断开。并且,至少一个第二触控电极220内设置有至少一个第一虚设电极DM1,且第一虚设电极DM1与第二触控电极220断开。
本公开的上述实施例,通过在第一触控电极210和第二触控电极220中设置第一虚设电极DM1,可减小第一触控电极210和第二触控电极220与显示基板1上的导电层的正对面积,从而可减小第一触控电极210和第二触控电极220与显示基板1上的导电层之间产生的电容值,降低电信号在第一触控电极210和第二触控电极220上的传输负载,以降低显示面板200的功耗。
在一些实施例中,如图8所示,位于拐角区A2的一个触控电极中的第一虚设电极DM1的面积,小于或等于位于主触控区A1的一个触控电极中的第一虚设电极DM1的面积。
可以理解的是,触控电极中第一虚设电极DM1的设计面积,应与该触控电极的面积正相关,即,触控电极的面积越大,该触控电极中第一虚设电极DM1的设计面积越大。
因此,由于位于拐角区A2的一个触控电极的面积,小于或等于位于主触控区A1的一个触控电极的面积,相应地,位于拐角区A2的一个触控电极中的第一虚设电极DM1的设计面积,应小于或等于位于主触控区A1的一个触控电极中的第一虚设电极DM1的设计面积。
在一些实施例中,如图8所示,触控结构2还包括第二虚设电极DM2,第二虚设电极DM2设置于多个电容单元23之间的间隙区域G内。
需要说明的是,第二虚设电极DM2的透光性能与触控电极(第一触控电极210和第二触控电极220)的透光性能接近,将第二虚设电极DM2设置于多个电容单元23之间的间隙区域G内,可保证触控结构2各区域的光线透过率的一致性,避免显示面板200在间隙区域G的光线透过率过大,有利于提高显示面板200的各区域的亮度均一性。
在一些实施例中,如图5所示,显示面板200包括位于主触控区A1沿第一方向X相对两侧的第一周边区BB1和第二周边区BB2,以及位于主触控区A1沿第二方向Y相对两侧的第三周边区BB3和第四周边区BB4。
如图5和图7A所示,触控结构2还包括多条第一触控走线31和多条第二触控走线32,多条第一触控走线31从第一周边区BB1延伸至第四周边区BB4,至少一条第一触控走线31与一个第一触控单元21电连接。多条第二触控走线32从第三周边区BB3经第二周边区BB2延伸至第四周边区BB4,至少一条第二触控走线32与一个第二触控单元22电连接。
示例性地,如图5和图7A所示,一条第一触控走线31与一个第一触控单元21电连接,一条第二触控走线32与一个第二触控单元22电连接。
继续参见图7A,至少一条第一触控走线31与第一电极E1电连接,至少一条第二触控走线32与第三电极E3电连接。
示例性地,如图7A所示,一条第一触控走线31与第一电极E1电连接,一条第二触控走线32与第三电极E3电连接。
如图5和图7A所示,至少一条第一触控走线31在参考面上的正投影,与至少一条第二触控走线32在参考面上的正投影不重叠。
示例性地,所有第一触控走线31在参考面上的正投影,与所有第二触控走线32在参考面上的正投影均不重叠。
采用上述走线设计,第一触控走线31在参考面上的正投影,与第二触控走线32在参考面上的正投影不重叠,第一触控走线31和第二触控走线32可以采用相同的材料并同层设置,保证了第一触控走线31和第二触控走线32的整体性和连续性,降低了第一触控走线31和第二触控走线32断线的风险。
需要说明的是,“同层”指的是采用同一成膜工艺制备用于形成特定图形的膜层,然后利用同一掩模板通过一次构图工艺形成的层结构。根据特定图形的不同,一次构图工艺可能包括多次曝光、显影或刻蚀工艺,而形成的层结构中的特定图形可以是连续的也可以是不连续的,这些特定图形还可能处于不同的高度或者具有不同的厚度。
并且,可以理解的是,参考图7A,显示面板200靠近拐角区A2的部分易被水汽和氧气侵蚀。采用上述走线设计,第一触控走线31和第二触控走线32中的一者不需要跨越另一者,避免了第一触控走线31或第二触控走线32的跳线设计,可降低触控走线因水汽和氧气侵蚀而断线的风险。
