鉴于上述至少一个技术问题,本申请实施例提供一种显示面板及显示装置,能够简化显示面板和显示装置的制备工艺。
为了实现上述目的,本申请实施例提供如下技术方案:
本申请实施例的第一方面提供一种显示面板,包括:发光区和位于发光区***的非发光区;显示面板包括沿厚度方向相对设置的出光侧和背光侧;
显示面板包括触控层和位于触控层中的滤光层,滤光层包括色阻,触控层包括第一触控走线和第二触控走线,第二触控走线位于第一触控走线的靠近出光侧;色阻包括第一色阻和第二色阻,第一色阻位于发光区,第二色阻、第一触控走线和第二触控走线均位于非发光区,且第二色阻位于第一触控走线和第二触控走线之间;第二色阻与第一色阻同层同材料设置,第一色阻与第二色阻之间具有间隙。
本申请实施例提供的显示面板,显示面板可以包括发光区和位于发光区***的非发光区;显示面板包括沿厚度方向相对设置的出光侧和背光侧。显示面板可以包括触控层和位于触控层中的滤光层,滤光层用于降低环境光的反射,从而改善显示面板的显示效果。由于将滤光层集成在触控层中,可以减少触控层和滤光层的总结构层的数量(例如,可以采用滤光层部分或完全替代触控层中的第一绝缘层和/或第二绝缘层),从而可以简化触控层和滤光层的制备工艺。滤光层可以包括色阻,触控层包括第一触控走线和第二触控走线,第二触控走线位于第一触控走线的靠近出光侧;色阻包括第一色阻和第二色阻,第一色阻位于发光区,第一色阻可以用于对环境光中与其自身颜色不同的光进行过滤,起到滤光的作用。第二色阻、第一触控走线和第二触控走线均位于非发光区,且第二色阻位于第一触控走线和第二触控走线之间,第二色阻可以电性隔离第一触控走线和第二触控走线。其中,第二色阻与至少部分第一色阻同层同材料设置,从而可以同时制备第一色阻和第二色阻,以简化第一色阻和第二色阻的制备工艺,从而可以简化显示面板和显示装置的制备工艺。
在一种可能的实现方式中,第一色阻包括多种颜色不同且间隔设置的子色阻,第二色阻与至少一种颜色的子色阻同层同材料设置;
可以实现的是,第一色阻的厚度范围为0.5μm-5μm;和/或,第二色阻的厚度范围为0.5μm-15μm;和/或,色阻的介电常数小于或等于10;和/或,色阻的表面阻抗大于或等于10

沿背光侧至出光侧的方向,过孔的开口逐渐增大。
这样,第二触控走线与过孔的孔壁面之间不易出现孔隙,两者之间连接较为稳定。
在一种可能的实现方式中,滤光层还包括遮光层,至少部分遮光层位于第二触控走线的靠近出光侧,
可以实现的是,遮光层在第一触控走线所在平面上的正投影覆盖第一触控走线;和/或,遮光层在第二触控走线所在平面上的正投影覆盖第二触控走线。

这样,可以避免工艺误差导致第一色阻与遮光层之间出现孔隙,而该孔隙处没有第一色阻将无法对光进行过滤,从而会影响显示面板的显示效果。
在一种可能的实现方式中,第一色阻与第二色阻之间具有间隙,遮光层位于间隙中;
可以实现的是,沿背光侧至出光侧的方向,第一色阻与第二色阻之间的间距逐渐增大。
这样,遮光层可以对第一触控走线、第二触控走线和第二色阻起保护作用。
在一种可能的实现方式中,触控层中设置有保护层,至少部分保护层位于第一色阻的靠近出光侧。
这样,保护层能够保护触控层中的其他结构层。
在一种可能的实现方式中,保护层包括第一保护层,第一保护层覆盖在第一色阻的靠近出光侧的面上;
可以实现的是,第一色阻的折射率小于第一保护层的折射率;
可以实现的是,显示面板包括粘接层,粘接层位于触控层的靠近出光侧,粘接层的折射率小于第一保护层的折射率。

示例性的,第一触控走线171和第二触控走线172可以为单层导电层形成,也可以是多层导电层的堆叠结构。
触控层170中可以集成有滤光层,滤光层可以用于替代触控层170中的除第一触控走线171和第二触控走线172以外的其他绝缘材料层的至少部分,从而可以使得显示面板100的整体厚度较小,以利于显示面板100的轻薄化;另外,薄化后的显示面板100的弯折性能较好。
以下对本申请实施例提供的滤光层进行说明。
滤光层可以用于降低环境光的反射,从而改善显示面板100的显示效果。
滤光层可以包括色阻182,色阻182可以用于对环境光中与其自身颜色不同的光进行过滤。色阻182可以采用有机材料形成,其柔性较高,有 利于显示面板100的弯折性能。
一些实施例中,如图1所示,色阻182可以包括第一色阻183,第一色阻183位于发光区100a。第一色阻183与像素一一对应的设置,第一色阻183在发光层120上的正投影覆盖像素,且与被覆盖的像素的颜色相同,以避免出现混光。例如,红色像素对应设置的第一色阻183为红子色阻,红子色阻可以阻挡蓝色像素和绿色像素发出的光线,并允许红色像素或者白色像素发出的红色光穿过。
可以理解的是,第一色阻183可以包括多种颜色不同且间隔设置的子色阻,例如,红子色阻、绿子色阻、蓝子色阻、白子色阻中的任意一者或多者。其原理已经阐述,不再赘述。
一些实施例中,色阻182可以包括第二色阻185,第二色阻185位于第一触控走线171和第二触控走线172之间,第二色阻185可以电性隔离第一触控走线171和第二触控走线172。例如,第二色阻185可以采用介电常数较低的有机材料形成,从而可以减小第二触控走线172上的寄生电容,以改善触控性能。
示例性的,色阻182的介电常数可以小于或等于10,例如,色阻182的介电常数可以1、3、5、7、10或10以下的任意数值,从而可以减小第二触控走线172上的寄生电容,以改善触控性能。色阻182的表面阻抗可以大于或等于10
11Ω/平方,例如,色阻182的表面阻抗可以为10
11Ω/平方、10
12Ω/平方、10
13Ω/平方或10
14Ω/平方等,从而能够较好的电性隔离第一触控走线171和第二触控走线172。
示例性的,如图3和图4所示,第二色阻185中可以具有沿厚度方向贯穿第二色阻185的多个过孔186,第一触控走线171和第二触控走线172之间通过过孔186搭桥相连。第二触控走线172覆盖在第二色阻185的背离发光层120一侧的面上,第二触控走线172延伸至过孔186中并覆盖在过孔186的孔壁面上,从而通过过孔186与第一触控走线171电性连接。
例如,沿背光侧至出光侧的方向,即沿发光层120至触控层170的方向,过孔186的开口逐渐增大。此时,过孔186的截面为倒梯形,过孔186的孔壁面为倾斜设置,过孔186的孔壁面包括靠近盖板160的第一端和靠近发光层120的第二端,在设置有过孔186的第二色阻185中,第一端相比于第二端更靠近该第二色阻185的边缘,即第一端相比于第二端朝向该第二色阻185的边缘倾斜。从而可以使得第二触控走线172较好的覆盖在 过孔186的孔壁面上,第二触控走线172与过孔186的孔壁面之间不易出现孔隙,第二触控走线172的附着较为稳定,不易断裂。
示例性的,第二触控走线172在第二色阻185所在平面上的正投影,可以位于第二色阻185的外边缘的内侧。即第二色阻185(包括过孔186)的尺寸可以大于第二触控走线172,第二色阻185的边缘将凸出于第二触控走线172的边缘,第二色阻185对第二触控走线172的支撑效果较好;另外,第二触控走线172的边缘距离发光层120中的阴极层较远,可以降低寄生电容,保证触控性能。
本实施例中,第二色阻185可以与第一色阻183的至少部分同层同材料设置,可以同时制备该部分第一色阻183和第二色阻185,即无需单独分别制备该部分第一色阻183和第二色阻185,可以简化第一色阻183和第二色阻185的制备工艺,从而可以简化显示面板100和显示装置的制备工艺。
示例性的,第二色阻185可以与第一色阻183中的多种颜色的子色阻中的至少一者的颜色相同,颜色相同的第二色阻185与该子色阻可以同层同材料设置。例如,第二色阻185可以与其中一种颜色的子色阻同时制备,此时,第一色阻183的厚度可以与第二色阻185的厚度相等。或者,第二色阻185可以与其中两种(图5)或三种颜色(图6)的子色阻同时制备。当第二色阻185与多种颜色的子色阻同时制备时,第二色阻185的厚度可以大于第一色阻183的厚度,第二色阻185的厚度可以小于该多种颜色的子色阻的厚度之和,此时第二色阻185的厚度较大,从而可以增大第二触控走线172与发光层120中的阴极层之间的距离,从而可以降低第二触控走线172与阴极层之间的寄生电容,改善触控性能。
本申请实施例中的“同层同材料”是指由同一材料形成基础膜层,对基础膜层进行图形化和/或者其他处理工艺后,将基础膜层的不同部分分别形成多种结构膜层。由该基础膜层形成的不同结构膜层的处理工艺可以相同或者不同,且形成的不同结构膜层可以具有相同或者不同的厚度,也可以处于同一水平面或者不同水平面。
示例性的,第一色阻183的厚度范围可以为0.5μm-5μm;另外,第二色阻185的厚度范围可以为0.5μm-15μm。例如,第一色阻183的厚度可以为0.5μm、1μm、2μm、3μm、5μm或者0.5μm-5μm之间的任意厚度。第二色阻185的厚度可以为0.5μm、2μm、5μm、10μm、15μm或者0.5μm-15 μm之间的任意厚度。从而可以避免色阻182的厚度过小,避免第二触控走线172的寄生电容较大,以保证触控性能。另外,还可以避免色阻182的厚度过大,避免对显示面板100的厚度造成较大影响,有利于显示面板100的轻薄化。
如图3所示,相邻的第一色阻183与第二色阻185之间可以具有间隙187,即相邻的第一色阻183与第二色阻185之间不连接而独立设置,从而存在间隙187。或者,相邻的第一色阻183和第二色阻185之间可以接触,例如,相邻的第一色阻183和第二色阻185之间可以为一体件,从而使得相邻的第一色阻183和第二色阻185可以同时制备,可以提高相邻的第一色阻183和第二色阻185的整体强度。
在相邻的第一色阻183和第二色阻185之间具有间隙187的实施方式中,沿背光侧至出光侧的方向,第一色阻183与第二色阻185之间的间隙187的间距逐渐增大。此时,第一色阻183的靠近第二色阻185一侧的侧壁面为倾斜设置,该倾斜设置的侧壁面可以为附着于其上的其他结构层提供较好的支撑,附着于该侧壁面上的其他结构层与该侧壁面之间的附着较为稳定,不易出现孔隙,其原理与过孔186的孔壁面倾斜设置类似,不再赘述。另外,第二色阻185的靠近第一色阻183的侧壁面为倾斜设置,其原理已经阐述,不再赘述。
本实施例中,如图3所示,滤光层还可以包括遮光层181,遮光层181可以由能够阻挡光的材料形成,能够吸收照射到遮光层181上的光线。遮光层181的光密度较大,光密度越大的材料吸光效果越好,例如遮光层181的光密度可以大于或等于1,从而较好的降低环境反射光,无需在显示面板100中设置偏光片,从而可以降低显示面板100的厚度。
以下对本申请实施例提供的遮光层181进行说明。
如图3所示,至少部分遮光层181位于第二触控走线172的靠近出光侧,即至少部分遮光层181位于第二触控走线172的背离发光层120的一侧。
示例性的,遮光层181在第一触控走线171所在平面上的正投影可以覆盖第一触控走线171,即遮光层181的尺寸大于等于第一触控走线171的尺寸,遮光层181在发光层120上的正投影可以覆盖第一触控走线171在发光层120上的正投影。从而可以避免环境光照在第一触控走线171上的反射,以提高显示面板100的显示效果。
其中,第一触控走线171所在平面是指第一触控走线171整体上大致所处的平面,第一触控走线171的长度延伸方向和宽度延伸方向均位于该平面内。
示例性的,遮光层181在第二触控走线172所在平面上的正投影可以覆盖 第二触控走线172。即遮光层181的尺寸大于等于第二触控走线172的尺寸,遮光层181在发光层120上的正投影可以覆盖第二触控走线172在发光层120上的正投影。从而可以避免环境光照在第二触控走线172上的反射,以提高显示面板100的显示效果。
如图1所示,至少部分第一色阻183延伸至非发光区100b,从而使得第一色阻183的面积较大,使得环境光更多的照射到第一色阻183上,对环境光过滤效果更好,可以更好降低环境光的反射,以提高显示面板100的显示效果。此时,遮光层181还可以位于第一色阻183的靠近出光侧,遮光层181可以覆盖在第一色阻183的边缘。在非发光区100b中,第一色阻183在遮光层181所在平面上的正投影与遮光层181部分重叠。例如,在制备遮光层181时,由于存在制程误差,遮光层181可能会偏离预定的位置,而遮光层181与第一色阻183的边缘重叠,可以避免遮光层181偏离预定位置后与第一色阻183之间出现孔隙,而该孔隙处没有第一色阻183将无法对光进行过滤,从而会影响显示面板100的显示效果。
示例性的,遮光层181的厚度可以为1μm-5μm,从而可以较好降低环境光的反射。遮光层181的表面阻抗可以大于或等于10
11Ω/平方,遮光层181的绝缘性较好。
在第一色阻183与第二色阻185之间具有间隙187的实施方式中,遮光层181还可以位于第一色阻183与第二色阻185之间的间隙187中。此时,遮光层181将第一触控走线171、第二触控走线172以及第二色阻185均包围在遮光层181围设形成的容置区域中。遮光层181覆盖的面积较大,可以更好的降低环境光的反射,且可以较好的防止相邻像素之间的混光。另外,遮光层181的透水率较低,能够阻止水、氧等入侵,从而对位于容置区域中的第一触控走线171、第二触控走线172以及第二色阻185起到保护作用,无需单独为触控层170设置隔离水、氧的结构层,有利于显示面板100的轻薄化。
当然的,也可以在触控层170中设置保护层,以进一步保护触控层170中的结构层,避免水、氧等入侵触控层170而造成损害。此时,由于遮光层181已经起到保护作用,保护层可以设置的较薄,从而避免保护层过厚影响显示面板100的厚度。
以下对本申请实施例提供的保护层进行说明。
至少部分保护层可以位于第一色阻183的靠近出光侧,即至少部分保护层可以位于第一色阻183的背离发光层120的一侧,从而对第一色阻183起到保 护作用。
示例性的,如图2a和图2b所示,保护层可以包括第一保护层174,第一保护层174位于第一色阻183的背离发光层120一侧的面上,从而可以对第一色阻183起保护作用。第一保护层174可以覆盖第一色阻183的部分面积或者全部面积。
示例性的,保护层可以包括第二保护层175,第二保护层175可以位于遮光层181的靠近出光侧的面上,另外,第二保护层175可以位于遮光层181的靠近背光侧的面上。第二保护层175可以位于遮光层181的沿厚度方向相对两侧的至少一侧。第二保护层175可以用于保护第二色阻185、第一触控走线171和第二触控走线172。
如图2a所示,第二保护层175位于遮光层181的背离发光层120的一侧,第二保护层175可以保护遮光层181。
如图2b所示,第二保护层175位于遮光层181的靠近发光层120的一侧,第二保护层175可以位于间隙187中。间隙187中可以仅设置有第二保护层175,或者,间隙187中可以同时设置有第二保护层175和遮光层181。当然的,间隙187中也可以填充有其他填充件。
可以理解的是,可以仅设置第一保护层174,也可以同时设置第一保护层174和第二保护层175。在同时设置有第一保护层174和第二保护层175的实施方式中,第一保护层174和第二保护层175可以为一体件,其保护效果更好。当然的,第一保护层174和第二保护层175也可以为两个独立的结构层。
示例性的,保护层的厚度可以处处相等,保护层背离发光层120一侧的面非齐平。此时,保护层可以呈薄膜状覆盖在遮光层181和/或第一色阻183上。保护层高度起伏呈弯折状态,能够在显示面板100弯折时提供较大的形变空间,以消散弯折应力,对显示面板100起保护作用。
示例性的,第一色阻183的折射率可以小于第一保护层174的折射率,从而可以降低发光层120的光在第一色阻183和第一保护层174之间的界面上的全发射,以提高出光效率。
示例性的,粘接层150的折射率可以小于第一保护层174的折射率,可以避免像素出射的光线经过粘接层150后过于集中而使得发光区的亮度差异较大,从而减轻大视角色偏现象。另外,可以通过调整第一保护层174的厚度,以使像素出射的光在第一保护层174的沿厚度方向的相对两个表面上的反射光发生破坏性干涉而相互抵消,从而增加像素发出的光的透过率,提高出光效 率。
可以理解的是,当第一保护层174和第二保护层175为一体件时,第二保护层175与第一保护层174的折射率相同。当第一保护层174和第二保护层175为两个独立的结构层时,第二保护层175与第一保护层174的折射率可以相同或不同,第二保护层175的折射率可以大于、等于或小于色阻182和/或粘接层150的折射率。
这里需要说明的是,本申请实施例涉及的数值和数值范围为近似值,受制造工艺的影响,可能会存在一定范围的误差,这部分误差本领域技术人员可以认为忽略不计。
最后应说明的是:以上各实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述各实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
