请参阅图1以及图2,图1为本申请提供的彩膜基板的平面透视示意图,图2为图1所示的彩膜基板沿AA’方向的第一种实施方式的截面示意图。
本申请提供一种彩膜基板100,其包括衬底10、遮光层20以及配向层30。该衬底10包括中心区域101以及围绕中心区域101的边缘区域102。遮光层20设置在衬底10上,且在边缘区域102上的遮光层20的表面具有凹凸结构。配向层30设置在遮光层20,并覆盖中心区域101和边缘区域102。
该衬底10可以是玻璃基板,其包括中心区域101和边缘区域102。中心区域101可以是用于显示画面的显示区,边缘区域102可以是非显示区。遮光层20的材料可以是黑色树脂材料,可以用于定义子像素区,并且还可以用于防止显示面板漏光。配向层30在遮光层20的表面流平时,由于在边缘区域102上的遮光层20的表面具有凹凸结构,因此,配向层30可以被阻挡在预设位置上,达到提高配向层30膜厚均匀性的目的。该预设位置可以有生产人员预先设定,具体可以根据实际显示面板的尺寸而定,在此不再赘述。配向层30的材料可以是聚酰亚胺。在实际生产过程中,可以将配向液涂敷到衬底10上并固化以达到锚定液晶分子的目的。然后,可以通过加电的方式形成预倾角,从而使液晶分子能够有序排列。
在本申请中,通过在边缘区域102上的遮光层20的表面形成凹凸结构,当在衬底10上涂布配向层30的材料时,位于边缘区域102的凹凸结构可以将配向层30的材料阻挡在预设位置上,避免了配向层30的材料外流导致配向层30各部分的膜厚存在差异,因此能够提高彩膜基板100的配向能力,从而提高显示面板的显示效果。
遮光层20包括第一遮光层201和第二遮光层202。第一遮光层201呈网格状设置在中心区域101上,第二遮光层202包括设置在边缘区域102上的主体部202A,以及设置在主体部202A上的多个突起部202B。多个突起部20B设置在主体部20A朝向配向层30的表面上,主体部20A与多个突起部20B形成凹凸结构。
需要说明的是,可以采用一道具有不同透光率的掩膜板,如半色调掩膜板,一并制成具有网格状结构的第一遮光层201,以及第二遮光层202。例如,采用一道掩膜板,该掩膜板具有第一透光区、第二透光区以及第三透光区。第一透光区的透光率为100%,第二透光区的透光率为50%,第三透光区的透光率为35%。然后,采用该掩膜板对衬底10上的遮光层20进行曝光显影,以形成具有网格状结构的第一遮光层201、主体部202A以及多个突起部202B。
在一些实施例中,第一遮光层201包括多个第一遮光条201A和多个第二遮光条201B。多个第一遮光条201A沿第一方向设置为多列,多个第二遮光条201B沿第二方向设置为多行。比如,第一方向为竖直方向,第二方向为水平方向,也即,第一方向与第二方向垂直。当然,第一方向也可以为水平方向,第二方向也可以为竖直方向,具体根据实际情况进行设置。图中仅仅以第一方向为竖直方向以及第二方向为水平方向示例。
进一步的,多个第一遮光条201A与多个第二遮光条201B交叉设置形成多个子像素区401,每个子像素区401上均设有一子像素41。子像素41包括红色子像素R、绿色子像素G和蓝色子像素B。
在一些实施例中,请参阅图2以及图3,图3为图1所示的彩膜基板沿BB’方向的第一种实施方式的截面示意图。
每个第一遮光条201A的厚度H、每个第二遮光条201B的厚度h以及主体部202A与每个突起部202B的厚度之和D均相等。
在本申请中,第一遮光条201A的厚度H指的是,第一遮光条201A朝向配向层30表面到第一遮光条201A朝向衬底10表面的距离。第二遮光条202A的厚度h指的是,第二遮光条202A朝向配向层30表面到第二遮光条202A朝向衬底10表面的距离。主体部202A与每个突起部202B的厚度之和D指的是,每个突起部202B远离主体部202A的表面到主体部202A朝向衬底10表面的距离。在本实施例中,每个第一遮光条201A的厚度H、每个第二遮光条201B的厚度h以及主体部202A与每个突起部202B的厚度之和D均相等,可以保证配向层30膜厚的均匀性,避免了配向层30的材料外流导致配向层30各部分的膜厚存在差异,因此能够提高彩膜基板100的配向能力,从而提高显示面板的显示效果。
在一些实施例中,请参阅图4,图4为图1所示的彩膜基板沿AA’方向的第二种实施方式的截面示意图。在中心区域101到边缘区域102的方向上,多个突起部202B的厚度逐渐递增。
比如,在中心区域101到边缘区域102的方向上设置有5个突起部202B。其中,第一个突起部202B的厚度为1毫米,第二个突起部202B的厚度为2毫米,第三个突起部202B的厚度为3毫米,第四个突起部202B的厚度为4毫米,第五个突起部202B的厚度为5毫米。在实际生产过程中,在遮光层20上涂敷配向层30的材料,由于在中心区域101到边缘区域102的方向上,多个突起部202B的厚度逐渐递增,可以保证配向层30膜厚的均匀性,避免了配向层30的材料外流导致配向层30各部分的膜厚存在差异,因此能够提高彩膜基板100的配向能力,从而提高显示面板的显示效果。
为了进一步保证配向层30膜厚的均匀性,因此,在一些实施例中,最远离中心区域101的突起部202B与主体部202A的厚度之和D等于每个第一遮光条201A的厚度H。
在一些实施例中,请参阅图5,图5为图1所示的彩膜基板沿AA’方向的第三种实施方式的截面示意图。在中心区域101到边缘区域102的方向上,相邻突起部202B之间的距离逐渐递减。
另外,为了保证配向层30膜厚的均匀性,在一些实施例中,分别以不同的速率在中心区域101和边缘区域102上形成配向层30。即,配向层30包括相互连接的第一部分301和第二部分302。第一部分301设置在中心区域101上,第二部分302设置在边缘区域102上,第一部分301以第一速率沉积,第二部分302以第二速率沉积。
在实际生产过程中,可以采用喷墨打印的方式在衬底10上形成配向层30,并且,可以通过改变压电陶瓷的电压来控制配向材料的液滴大小,从而使得第二配向层302表面与第一配向层301的表面平齐,可以保证配向层30膜厚的均匀性,因此能够提高彩膜基板100的配向能力,从而提高显示面板的显示效果。
相应的,请参阅图6,图6为本申请提供的显示面板的结构示意图。本申请还提供一种显示面板1,包括本申请任一实施例的彩膜基板100、阵列基板200以及设置在彩膜基板100和阵列基板200之间的液晶层300。彩膜基板100的具体结构请参阅前面实施例,在此不再赘述。
以上对本申请实施例提供的彩膜基板以及显示面板进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请。同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
