下面将详细描述本申请的各个方面的特征和示例性实施例。在下面的详细描述中,提出了许多具体细节,以便提供对本申请的全面理解。但是,对于本领域技术人员来说很明显的是,本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请的更好的理解。
需要说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括……”限定的要素,并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
申请人经研究发现,显示面板中包括基板、发光功能单元以及隔离结构13’,隔离结构13’围合形成开口部,开口部用于容纳发光功能单元。发光功能单元位于基板一侧,包括沿远离基板方向层叠设置的第一电极、发光功能层和第二电极1213’,相邻发光功能单元的第二电极1213’通过隔离结构13’电连接。第二电极1213’采用蒸镀工艺制备形成,蒸镀源2’包括多个蒸镀孔,多个蒸镀孔沿第一方向x’排列,蒸镀过程中,蒸镀源2’的沿预设方向移动,其中,预设方向平行于显示面板所在平面且垂直于第一方向x’。如图1所示,当开口部在基板上的正投影为矩形环状结构时,开口部包括朝向开口部内侧的四个侧壁1323’,侧壁1323’所在平面与基板所在平面所成的交线L1与第一方向x’不平行、即相交时,如图2所示,会造成侧壁1323’中沿交线L1方向排列的各区域内、蒸镀材料分布的厚度分布一致性较差。同时,如图3和图4所示,蒸镀源的实际的蒸镀角(图4中S’代表蒸镀材料的实际最大分布范围的边缘,实际蒸镀角与S’相关)会
比蒸镀源的原蒸镀角θ(图3中S代表蒸镀材料的原最大分布范围的边缘,原蒸镀角与S相关)小,其中,原蒸镀角θ指的是在垂直于第一方向x’的剖面上两个最大蒸镀路径之间的夹角,蒸镀源的实际的蒸镀角指的是在垂直于L1所在平面方向上两个最大蒸镀路径之间的夹角。具体可如图4所示,图4中示出了蒸镀角θ的一半以及实际蒸镀角θ’的一半,即β和β’,其中,当第一方向x’与交线L1呈夹角γ时,可由图4得出:tanβ'/tanβ=cosγ·,即实际的蒸镀角2β’小于蒸镀源的原蒸镀角2β,从而如图5所示,使得侧壁1323’上的第二电极的高度较小。如图6所示,当交线L1与第一方向x’平行时,在蒸镀源2’沿平行于显示面板所在平面且垂直于第一方向移动过程中,可实现在相对的两个侧壁1323’上形成高度较高且厚度较为均一的蒸镀材料,从而形成与隔离结构13’搭接面积较大、且厚度较为均一的第二电极1213’。但是现有的显示面板为实现良好的显示效果需进行像素的形状以及排布设计,而蒸镀源2’的位置已固定,调节不便且调节成本较高,从而会出现显示面板中交线L1与第一方向x’不平行、即相交的情况,从而形成在侧壁1323’上高度分布较低且厚度不均一的第二电极1213’,影响显示面板的电阻和功耗以及显示面板的显示质量。基于对上述问题的研究,申请人提供了一种显示面板及其制备方法、显示装置,以降低显示面板的电阻,从而降低显示面板的功耗,并提升显示面板的显示质量。
为了更好地理解本申请,下面结合图7至图12根据本申请实施例的显示面板及显示装置进行详细描述。
请参阅图7至图10,本申请实施例提供了一种显示面板1,包括基板11、多条第一扫描线111、隔离结构13和多个发光功能单元121。多条第一扫描线111位于基板11一侧,且多条第一扫描线111沿第一方向x排列。隔离结构13形成于基板11一侧,且隔离结构13围合形成开口部131,隔离结构13包括第一隔离部132,第一隔离部132包括朝向开口部131一侧的侧面1323,侧面1323包括第一表面1320,第一表面1320所在平面与基板11所在平面相交并形成第一交线1325,第一交线1325与第一方向x呈第一预设角度。发光功能单元121设置于基板11上并对应开口部131设
置,发光功能单元121包括第一电极1211、发光功能层1212和第二电极1213。其中,第二电极1213与隔离结构13接触,第一预设角度大于或等于0°且小于45°。
具体地,基板11一侧可形成有驱动电路层110,第一扫描线111形成于驱动电路层110内。
具体地,第二电极可与隔离结构13中的第一表面1320接触。本申请提供的显示面板1中包括基板11、多条第一扫描线111、隔离结构13和多个发光功能单元121。多条第一扫描线111形成于基板11一侧,且多条第一扫描线111沿第一方向x排列,以实现对发光功能单元121对应的驱动电路的扫描。隔离结构13形成于基板11的一侧,且隔离结构13围合形成开口部131,发光功能单元121形成于开口部131内,发光功能单元121包括沿远离基板11方向层叠设置的第一电极1211、发光功能层1212和第二电极1213。隔离结构13包括第一隔离部132,第一隔离部132包括朝向开口部131一侧的侧面1323,侧面1323包括第一表面1320,侧面1323还可以包括与第一表面1320相交的其它表面,本申请不做特别限定。第一表面1320所在平面与基板11所在平面相交并形成第一交线1325,或者说第一表面1320与基板11所在平面的平行面相交并形成第一交线1325;具体地,第一交线1325可为第一表面1320靠近基板11的一端的边缘线。如图11所示,在制备过程中,用于蒸镀第二电极1213的蒸镀源2上各蒸镀孔21的排列方向通常和第一方向x平行,本申请提供的显示面板1中,第一交线1325与第一方向x呈第一预设角度,将第一预设角度设置为大于或等于0°且小于45°,从而可使得蒸镀源2中沿平行于第一方向x排列的蒸镀孔21所发出的蒸镀材料在第一表面1320上的分布均匀,具体地,该“均匀”指的是第一表面1320中沿第一交线1325方向的厚度分布一致性强,从而提升了蒸镀材料所形成的第二电极1213与第一表面1320的接触部分的厚度分布均一性,使得第二电极1213沿第一交线1325方向排列的各区域电阻均匀性更强。同时使得实际的蒸镀角较大,从而提升第一表面1320上第二电极1213的高度,提升隔离结构13与第二电极1213的搭接面积,从而使得发光功能单元121各部分发光的亮度均一性增强且电阻减小、搭
接稳定性提高,有助于提升显示面板1的显示质量。
其中,上述“高度”指的是蒸镀材料在隔离结构13上的爬升距离。爬升距离即为蒸镀材料在第一表面1320上由靠近基板11一端向远离基板11一端延伸的最小距离。
具体地,当第一表面1320中第二电极1213沿第一交线1325方向的厚度分布一致性强时,可使得发光功能单元121各位置处的电阻差异较小,从而可提升发光功能单元121的亮度均一性。第一表面1320上第二电极1213的高度较高,可降低用于驱动发光功能单元121的驱动电路内的总电阻,使得发光功能单元121的亮度更高,从而有助于降低显示面板1的功耗。同时会使得第一表面1320与第二电极1213的接触面积更大,提升二者连接的稳定性和可靠性。
如图11所示,在显示面板1的制备过程中,显示面板1在制备完成前包括待蒸镀状态,即在制备第二电极1213之前的状态,由于加工制造工艺设备的限制,蒸镀源2与待蒸镀状态的显示面板1的相对位置是固定的,通常为蒸镀源2中蒸镀孔21的排列方向平行于第一方向x,蒸镀源2的预设方向m平行于基板11且垂直于第一方向x。更改蒸镀源2与待蒸镀状态的显示面板1的相对位置会造成制备成本的显著增加。在上述实施方式中,通过使得隔离结构13的侧面1323包括第一表面1320,从而可在不改变开口部131在显示面板1内排列方式、以及蒸镀源2和待蒸镀显示面板1相对位置的基础上,仅通过改变开口部131侧壁的形状改善第二电极1213与第一隔离部132的搭接部分的分布均一性,从而可在提升显示面板1质量的同时节省制备成本。
上述实施方式中,隔离结构13的材质为导电材质,从而可实现将相邻发光功能单元121之间的第二电极1213电连接,以减少显示面板1内对第二电极1213的供电线的数量,从而简化显示面板1内的布线并降低制备成本。
上述实施方式中,基板11可以由诸如玻璃、聚酰亚胺(PI)、聚碳酸酯(PC)、聚醚砜(PES)、聚对苯二甲酸乙二醇酯(PET)、聚萘二甲酸乙二醇酯(PEN)、多芳基化合物(PAR)或玻璃纤维增强塑料(FRP)等聚合物材料形成。
可以是透明的、半透明的或不透明的。本申请实施例中的基板11还可以为柔性基板11,由厚度较薄的聚合物形成,例如聚酰亚胺。基板11还可以包括缓冲层,缓冲层可以包括多层无机、有机层层叠结构,以阻挡氧和湿气,防止湿气或杂质通过基板11扩散,并且在基板11的上表面上提供平坦的表面,具体结构本申请不再赘述。
在一种可行的实施方式中,第一预设角度大于或等于0°且小于15°。
在上述实施方式中,当第一预设角度为0°时,蒸镀材料在第一表面1320上分布的均匀度最佳。将第一预设角度设置为大于或等于0°且小于15°,从而可保证沿第一方向x排列的蒸镀孔所发出的蒸镀材料在第一表面1320上的分布均一性较强、高度较高,同时兼顾了制备工艺的精度对第一预设角度造成的偏差。
在一种可行的实施方式中,如图8所示,第一交线1325与第一方向x平行。此时实际蒸镀角即为蒸镀源2的原蒸镀角,蒸镀效果最佳。从而在不改变蒸镀源2和待蒸镀显示面板1相对位置的基础上,提升第二电极1213与第一隔离部132的搭接面积,降低第二电极1213的电阻,从而降低显示面板1的功耗,并提升了发光功能单元121的发光质量,同时兼顾了生产成本。
在一种可行的实施方式中,如图7所示,显示面板1包括多条数据线112,多条数据线沿第一方向x延伸。
在一种可行的实施方式中,多条第一扫描线111沿第二方向y延伸,第一方向x与第二方向y垂直。在一种可行的实施方式中,如图10所示,第一隔离部132包括平行于基板11的顶面1321和底面1322,顶面1321位于底面1322背离基板11一侧,第一表面1320与底面1322相连接。
在上述实施方式中,第二电极1213包括位于第一隔离部132围合形成的开口部131内部的第一部分1214,第一部分1214在基板11上的正投影与第一隔离部132在基板11上的正投影无交叠。第二电极1213还包括与第一表面1320接触的第二部分1215,第一部分1214和第二部分1215连续设置。第一表面1320与底面1322相连接,并由底面1322向顶面1321方向延伸,从而在形成第二电极1213的过程中,可提升第一表面1320上
的第二部分1215与第一部分1214之间的连接良率。无需考虑第二电极1213的膜层厚度即可实现第一部分1214与第二部分1215的连续设置,可简化制备工艺。
在一种可行的实施方式中,如图8所示,第一隔离部132在基板11上的正投影图形的边缘呈锯齿状。
在上述实施方式中,第一隔离部132在基板11上的正投影图形的边缘呈锯齿状,是指第一隔离部132围合形成的开口在基板11上的正投影的图形的边缘呈锯齿状,从而可实现将不同的第一表面1320连接并围合形成开口部131。
在一种可行的实施方式中,如图10所示,第一隔离部132包括第一截面1324,第一截面1324垂直于基板11,第一截面1324的形状为正梯形。
在上述实施方式中,第一截面1324的形状为正梯形,即第一隔离部132的侧面1323较基板11所在平面倾斜设置,且侧壁远离基板11的一端较靠近基板11的一端向远离开口部131中心的方向切斜,从而可使得侧壁更容易承接蒸镀材料,使得形成的第二电极1213更易与侧壁接触并在侧壁上连续设置。
在一种可行的实施方式中,如图8和图9所示,侧面1323还包括第二表面1326,第二表面1326与第一表面1320沿围绕开口部131中心的方向交替设置,第二表面1326与第一表面1320相连接,第二表面1326所在平面与基板11所在平面相交并形成第二交线1327,第二交线1327与第一方向x呈第二预设角度α2,第二预设角度α2大于45°且小于或等于90°。
在上述实施方式中,第一隔离部132的侧面1323还包括第二表面1326,第二表面1326与第一表面1320沿围绕开口部131中心的方向交替设置,相邻第一表面1320之间通过第二表面1326连接,从而围合形成开口部131,并实现开口部131形状的设计。
在上述实施方式中,第二表面1326所在平面与基板11所在平面相交并形成第二交线1327,或者说第二表面1326与基板11所在平面的平行面相交并形成第二交线1327,第二交线1327与第一方向x呈第二预设角度α2,第二预设角度α2大于45°且小于或等于90°,即第二表面1326较
第一表面1320不易接收蒸镀材料,其作用仅为连接相邻的第一表面1320。第二预设角度α2在自身取值范围内越大、蒸镀源2在第二表面1326上的实际蒸镀角越小,其连接的两个第一表面1320沿第一方向x的距离越近,从而可使得在开口部131沿第一方向x的尺寸一定的前提下,增大第一表面1320、第二表面1326在预设方向上的投影总面积中、第一表面1320在预设方向上的投影面积的占比,其中,预设方向平行于基板11且垂直于第一方向x。从而可进一步提升第一隔离部132与第二电极1213的接触面积。
在一种可行的实施方式中,如图8所示,第二预设角度α2等于90°。
在上述实施方式中,当第二预设角度α2为90°时,第一表面1320、第二表面1326在预设方向上的投影总面积中、第一表面1320在预设方向上的投影面积的占比最大,效果最佳。
在一种可行的实施方式中,如图10和图12所示,第一隔离部132包括平行于基板11的顶面1321和底面1322,顶面1321位于底面1322背离基板11一侧,第二表面1326与底面1322的交线长度a小于第一表面1320与底面1322的交线长度A。
第一表面1320用于承接蒸镀材料以形成与第一隔离部132接触的第二电极1213,第二表面1326用于连接相邻的第一表面1320,因此将第一表面1320与底面1322的交线长度大于第二表面1326与底面1322的交线长度,可提升侧壁与第二电极1213的搭接面积,从而提升二者搭接良率。
在一种可行的实施方式中,如图13所示,开口部131中,第一表面1320与第二表面1326的交线靠近基板11的一端在基板11上的正投影位于一个第一虚拟四边形14上、或位于一个虚拟圆形上(图中未示出),第一虚拟四边形14的侧边与第一方向x呈第一夹角c1,第一夹角c1的度数大于0°且小于90°。
在上述实施方式中,开口部131中,第一表面1320与第二表面1326的交线靠近基板11的一端在基板11上的正投影位于一个第一虚拟四边形14上、或位于一个虚拟圆形上,一方面可便于制备,另一方面可降低第一表面1320与第二表面1326的设置对开口率的影响。同时,显示面板1为矩形显示面板1时,矩形显示面板1通常包括与第一方向x平行的两个侧
边以及与第一方向x垂直的两个侧边,将第一虚拟四边形14的侧边与第一方向x设置为二者形成的第一夹角c1度数大于0°且小于90°,从而可降低显示中出现条纹等显示不良的概率,降低显示的锯齿感,使得画面显示的更好。
在一种可行的实施方式中,如图13所示,第一虚拟四边形14为矩形,第一夹角c1为45°。
在上述实施方式中,第一夹角c1为45°可进一步降低显示中出现条纹等显示不良的概率,降低显示的锯齿感,使得画面显示的更好。
在一种可行的实施方式中,如图1所示,多个发光功能单元121包括多个第一发光功能单元1216、多个第二发光功能单元1217和多个第三发光功能单元1218,其中,每个第一发光功能单元1216位于一个第二虚拟四边形18的内部,每个第二虚拟四边形18中两个相对的顶点分别与第二发光功能单元1217的中心重合、另外两个相对的顶点分别与第三发光功能单元1218的中心重合,第一发光功能单元1216、第二发光功能单元1217和第三发光功能单元1218的个数比为2:1:1。
在这种排布方式中,各个发光功能单元121中的各个第二电极1213的形状优选为相同,以便于制备。
上述实施方式中,第一发光功能单元1216的颜色为绿色、第二发光功能单元1217的颜色为红色或蓝色,当第二发光功能单元1217的颜色为红色时,第三发光功能单元1218的颜色为蓝色,当第二发光功能单元1217的颜色为蓝色时,第三发光功能单元1218的颜色为红色。
在上述实施方式中,可不改变发光功能单元121的排布方式的基础上,对第一隔离部132进行改进,第一隔离部132朝向开口部131内的侧面上形成有第一表面1320,以提升第二电极1213与第一隔离部132之间的搭接效果。

隔离结构13中、第一隔离部132在基板11上的正投影位于第二隔离部133在基板11上的正投影内,第二隔离部133在基板11上的正投影面积大于第一隔离部132在基板11上的正投影面积,从而在第一隔离部132与第二隔离部133之间形成阶梯部。在制备各种颜色的发光功能单元121时,先整面形成一种颜色的发光功能单元121中的各个膜层,然后通过刻蚀以在指定开口部131处形成该种颜色的发光功能单元121,并暴露用于容纳其它颜色的发光功能层1212的开部口。不同颜色的发光功能单元121分多次制备,上述制备过程中无需使用金属精细掩膜板,从而可节省制备成本。隔离结构13可采用深色材料制备形成,从而可起到遮光的效果,防止相邻发光功能单元121之间的串光,并阻隔隔离结构13下方结构对外界光线反射后形成的反射光线由显示面板1出光面出射的概率,从而降低显示面板1的反射率。
在一种可行的实施方式中,如图14所示,第二隔离部133在基板11上的正投影图形的边缘呈锯齿状。
在上述实施方式中,第二隔离部133在基板11上的正投影图形的边缘呈锯齿状,是指第二隔离部133围合形成的开口在基板11上的正投影图形的边缘呈锯齿状,从而可通过改变第二隔离部133的形状与第一隔离部132的形状相适配,第二隔离部133围合形成的开口在基板11上的正投影图形的边缘所呈锯齿状可位于第一隔离部132在基板11上的正投影图形的边缘所呈锯齿状内部,且两个锯齿状图形的边缘相互平行,从而可使得第二隔离部133对第一隔离部132各个位置的遮挡效果相同,有助于提升第二电极1213的高度均一性。
在一种可行的实施方式中,如图10所示,还包括像素定义层17,像素定义层17位于基板11的一侧,像素定义层17包括像素限定部171和由像素限定部171限定的第一开口172,至少部分发光功能层1212设置在第一开口172内。
像素定义层17可对发光功能单元121的位置进行限定,同时对第一电极1211的边缘进行覆盖,以实现第一电极1211之间以及第一电极1211与隔离结构13之间的绝缘。
隔离结构13可采用深色材料制备形成,此时,像素定义层17可采用透光的无机材料,以进一步降低材料成本。

在一种可行的实施方式中,如图15所示,像素限定部171背离基板11的一侧设有凹槽173,隔离结构13位于凹槽173内。可降低隔离结构13背离基板11一侧与基板11表面之间的距离,从而可降低隔离结构13对发光功能层1212发出的大角度光线的遮挡,从而可提升显示面板1的显示亮度。
在一种可行的实施方式中,如图16所示,像素限定部171包括第二开口174,隔离结构13位于第二开口174内。其中,第二开口174可为贯穿像素限定部171厚度方向的通孔。
像素定义层17的设置可实现第一电极1211与隔离结构13之间的绝缘,同时像素定义层17可对第一电极1211进行保护,当第一电极1211包括易被氧化的材质时,例如银,可降低第一电极1211被氧化的概率。隔离结构13直接位于基板11上,从而可进一步降低隔离结构13背离基板11一侧与基板11表面之间的距离,从而可降低隔离结构13对发光功能单元121发出的大角度光线的遮挡,以提升显示面板1的显示亮度。
在一种可行的实施方式中,侧面1323还包括第二表面1326,第二表面1326与第一表面1320沿开口部131的周向交替设置,第二表面1326与第一表面1320相连接。如图17所示,开口部131中,第一表面1320与第二表面1326的交线靠近基板11的一端在基板11上的正投影位于虚拟圆形15上,第一开口172在基板11上的正投影图形包括圆形176,圆形176与虚拟圆形15中心重合。

本申请第四方面还提供了一种显示面板1的制备方法,如图20所示,
包括:
S100,提供基板11。
S200,在基板11一侧形成隔离结构13,隔离结构13围合形成开口部131,隔离结构13包括第一隔离部132,第一隔离部132包括朝向开口部131一侧的侧面1323,侧面1323包括第一表面1320,第一表面1320所在平面与基板11所在平面相交并形成第一交线1325,第一交线1325与第一方向x呈第一预设角度,第一预设角度大于或等于0°且小于45°。
S300,在基板11上形成多个发光功能单元121,发光功能单元121对应开口部131设置,包括:在基板11上形成第一电极1211;在第一电极1211背离基板11的一侧形成发光功能层1212;在发光功能层1212背离基板11的一侧形成第二电极1213,包括:提供蒸镀源2,蒸镀源2包括多个蒸镀孔,蒸镀孔沿第三方向排列;将蒸镀源2与基板11的位置关系设置为蒸镀源2位于隔离结构13背离基板11的一侧,且第三方向平行于第一方向x。
上述制备方法中,通过在第一隔离结构13朝向开口部131的一侧设置第一表面1320,使得第一表面1320所在平面与基板11所在平面相交并形成第一交线1325,或者说第一表面1320与基板11所在平面的平行面相交并形成第一交线1325,第一交线1325与第一方向x呈第一预设角度,第一预设角度大于或等于0°且小于45°,并在制备过程中,使得蒸镀源2中蒸镀孔的排列方向平行于第一方向x,从而可提升蒸镀源2与第一表面1320之间的实际蒸镀角,使其接近蒸镀源2的原蒸镀角或与原蒸镀角相等,从而使得第一表面1320上可附着更为均一且高度更高的蒸镀材料,实现第二电极1213面积以及电阻均一性的提升,从而有助于提升显示面板1的显示质量。
由于本申请第四方面实施例提供的显示装置用于形成上述第一方面、第二方面任一实施例的显示面板1,因此本申请第四方面实施例提供的显示装置具有上述第一方面、第二方面任一实施例的显示面板1具有的有益效果,在此不再赘述。
上述实施方式中,步骤S100和S200之间还包括:
在基板11一侧形成多条第一扫描线111,多条第一扫描线111沿第一方向x排列。
在上述实施方式中,基板11上还形成有多条沿第一方向x排列的第一扫描线111,可在基板11上形成第一表面1320时,以第一扫描线111所限定出的第一方向x作为参考进行制备。现有的显示面板1的加工制造工艺设备中,待蒸镀的显示面板1中的第一扫描线111所限定出的第一方向x与蒸镀源2中蒸镀孔的排列方向一般设置为平行,从而可在不改变蒸镀源2与待蒸镀状态的显示面板1的相对位置的前提下,使得第一表面1320与蒸镀源2的位置关系可使得第二电极1213在第一表面1320上的形成效果更好。在一种可行的实施方式中,还包括:沿预设方向移动蒸镀源2,以使蒸镀孔蒸镀出的蒸镀材料形成于第一表面1320,以形成第二电极1213,第二电极1213与第一表面1320接触,其中,预设方向平行于基板11所在平面且垂直于第一方向x。
上述实施方式中,蒸镀源2沿垂直于第一方向x的预设方向m移动,可实现在相对的两个侧壁1323上形成高度较高且厚度较为均一的蒸镀材料,从而形成与隔离结构13搭接面积较大、且厚度较为均一的第二电极1213。
在一种可行的实施方式中,所述第一预设角度为0°,蒸镀材料在第一表面1320上分布的均匀度最佳。将第一预设角度设置为大于或等于0°且小于15°,从而可保证沿第一方向x排列的蒸镀孔所发出的蒸镀材料在第一表面1320上的分布均一性较强、高度较高,同时兼顾了制备工艺的精度对第一预设角度造成的偏差。
在一种可行的实施方式中,侧面1323还包括第二表面1326,第二表面1326与第一表面1320沿围绕开口部131中心的方向交替设置,第二表面1326与第一表面1320相连接,第二表面1326所在平面与基板11所在平面相交并形成第二交线,或者说第二表面1326与基板11所在平面的平行面相交并形成第二交线,第二交线与第一方向x呈第二预设角度,第二预设角度大于45°且小于或等于90°;即第二表面1326较第一表面1320不易接收蒸镀材料,其作用仅为连接相邻的第一表面1320。第二预设角度α2在自身取值范围内越大、蒸镀源2在第二表面1326上的实际蒸镀角越小,
其连接的两个第一表面1320沿第一方向x的距离越近,从而可使得在开口部131沿第一方向x的尺寸一定的前提下,增大第一表面1320、第二表面1326在预设方向上的投影总面积中、第一表面1320在预设方向上的投影面积的占比,其中,预设方向平行于基板11且垂直于第一方向x。从而可进一步提升第一隔离部132与第二电极1213的接触面积。
在一种可行的实施方式中,第二表面1326与底面1322的交线长度小于第一表面1320与底面1322的交线长度;第一表面1320用于承接蒸镀材料以形成与第一隔离部132接触的第二电极1213,第二表面1326用于连接相邻的第一表面1320,因此将第一表面1320与底面1322的交线长度大于第二表面1326与底面1322的交线长度,可提升侧壁与第二电极1213的搭接面积,从而提升二者搭接良率。
在一种可行的实施方式中,第一隔离部132在基板11上的正投影图形的边缘呈锯齿状,是指第一隔离部132围合形成的开口在基板11上的正投影图形的边缘呈锯齿状;从而可实现将不同的第一表面1320连接并围合形成开口部131。
依照本申请如上文的实施例,这些实施例并没有详尽叙述所有的细节,也不限制该发明仅为的具体实施例。显然,根据以上描述,可作很多的修改和变化。本说明书选取并具体描述这些实施例,是为了更好地解释本申请的原理和实际应用,从而使所属技术领域技术人员能很好地利用本申请以及在本申请基础上的修改使用。本申请仅受权利要求书及其全部范围和等效物的限制。
