Description

显示面板、显示面板的制作方法和显示装置
本申请分别要求于2019年4月8日提交中国专利局,申请号为CN201910275099.9,申请名称为“一种显示面板的阵列基板、制作方法和显示装置”、于2019年4月8日提交中国专利局,申请号为CN201910275098.4,申请名称为“一种显示面板的彩膜基板、制作方法和显示装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域,尤其涉及一种显示面板、显示面板的制作方法和显示装置。
背景技术
这里的陈述仅提供与本申请有关的背景信息,而不必然地构成现有技术。
薄膜晶体管显示装置(Thin Film Transistor Liquid Crystal Display,TFT-LCD)领域中,液晶显示面板主要由彩膜基板和阵列基板,以及两片基板之间填充的液晶层构成。两片基板上均设有配向膜,液晶能够沿着配向膜上的沟槽进行配向排列,并通过电场对液晶的控制,形成显示画面。两片基板通过封框胶固定安装。通常会在基板上涂布一层配向液(PI)来形成预倾角以利于液晶的在显示时具有固定倒向。配向液是一种具有流动性的化学液体,涂布之后会向非显示区扩散流动,所以会在配向液涂布范围的边缘设置挡墙来防止配向液超过框胶边缘。
配向液达到挡墙处时会发生回流堆积,导致配向液的厚度增加,显示不均匀,或着流到框胶处造成框胶脱落。
发明内容
本申请的目的是提供一种显示面板、显示面板的制作方法和显示装置,防止配向液回流或流到框胶处。
本申请公开了一种显示面板,包括阵列基板;彩膜基板;框胶,所述阵列基板和所述彩膜基板通过所述框胶对组;以及设置于所述阵列基板和/或彩膜基板上的多个挡墙,设置为阻挡配向液的流动;多个所述挡墙垂直于所述显示面板的框胶涂布方向设置,多个所述挡墙之间具有高度差,每个所述挡墙之间相隔一段间距。
本申请还公开了一种显示装置,包括显示面板,所述显示面板包括:彩膜基板;阵列基板;框胶,所述彩膜基板和阵列基板通过所述框胶对组;以及设置于所述阵列基板和/或彩膜基板上的多个挡墙,设置为阻挡配向液的流动;多个所述挡墙垂直于所述显示面板的框胶 涂布方向设置,多个所述挡墙之间具有高度差,每个所述挡墙之间相隔一段间距。
本申请还公开了一种显示面板的制作方法,包括步骤:
制作阵列基板;
制作彩膜基板;
在所述阵列基板和/或彩膜基板上垂直于所述显示面板的框胶涂布的方向设置多个不同高度的挡墙,每个所述挡墙之间相隔一段间距;以及
用框胶将所述阵列基板和所述彩膜基板对组形成显示面板。
本申请在阵列基板上用金属层来垫高挡墙的方法,按配向液流动的方向设置多个高度逐个递增的挡墙,当配向液流到挡墙,会被分步阻挡,最后设置一个附加挡墙和沟槽,有效防止配向液流到胶框处,防止框胶脱落;然后每当配向液漫过一个挡墙的时候,流速就会有所降低,使配向液不会由于流速较快遇到挡墙后产生回流堆积而导致配向液厚度增加,使显示面板的亮度更均匀。

具体实施方式
需要理解的是,这里所使用的术语、公开的具体结构和功能细节,仅仅是为了描述具体实施例,是代表性的,但是本申请可以通过许多替换形式来具体实现,不应被解释成仅受限 于这里所阐述的实施例。
在本申请的描述中,术语“第一”、“第二”仅用于描述目的,而不能理解为指示相对重要性,或者隐含指明所指示的技术特征的数量。由此,除非另有说明,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征;“多个”的含义是两个或两个以上。术语“包括”及其任何变形,意为不排他的包含,可能存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和/或其组合。
另外,“中心”、“横向”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系的术语,是基于附图所示的方位或相对位置关系描述的,仅是为了便于描述本申请的简化描述,而不是指示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。
此外,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,或是两个元件内部的连通。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本申请中的具体含义。
框胶会涂布在阵列基板侧,阵列基板侧的配向液不能涂布超过框胶的位置,否则会出现框胶脱落或显示异常。这样配向液的边缘要处在显示区和框胶的内侧边缘之间。一般会在配向液的边缘设置挡墙来防止配向液超过框胶的边缘。一般是设置一道或几道支撑柱墙来形成配向液的挡墙,挡墙的高度是配向液的厚度的10倍以上。随着市场的进化,人们越来越倾向于显示器的窄边框化,这样对配向膜在显示区域和框胶之间的位置的要求更加严格。
如图1所示,就有阵列基板侧的支撑柱突起式的配向液挡墙140会使配向液回流堆积在显示区附近,导致配向液的厚度增加,显示面板100点亮时出现亮度不均匀,或者如图2所示,配向液越过挡墙140流到框胶130下,造成框胶130脱落。
下面参考附图和可选的实施例对本申请作进一步说明。
如图3所示,本申请实施例公布了一种显示装置200,所述显示装置200包括显示面板100,所述显示面板100包括彩膜基板110、阵列基板160和框胶130;所述彩膜基板110和所述阵列基板160通过框胶130对组。
如图4所示,所述阵列基板160包括衬底114、金属层162、绝缘层161、配向层120和多个挡墙140;金属层162设置于衬底114上,所述金属层162位于所述衬底114的非显示区内;绝缘层161设置于衬底114上,覆盖于所述金属层162上;配向层120和多个挡墙140均设置于所述阵列基板160的所述绝缘层161上,多个挡墙140设置为阻挡配向液的流动;多个所述挡墙140垂直于所述框胶130涂布的方向设置,多个所述挡墙140之间具有高度差,部分所述挡墙140设置于所述绝缘层161上对应金属层162的位置。
本申请在阵列基板160上用金属层162来垫高挡墙140的方法,按配向液流动的方向设置多个高度逐个递增的挡墙140,当配向液流到挡墙140,会被分步阻挡,最后设置一个附加挡墙150和沟槽113,有效防止配向液流到胶框处,防止框胶130脱落;然后每当配向液漫过一个挡墙140的时候,流速就会有所降低,使配向液不会由于流速较快遇到挡墙140后产生回流堆积而导致配向层120厚度增加,使显示面板100的亮度更均匀。
具体的,所述阵列基板160包括设置于显示区内的所述绝缘层161上的色阻层116,所述挡墙140的材料与所述色阻层116的材料相同,所述挡墙140包括上层结构141和下层结构142,所述挡墙140为单层结构或多层堆叠结构;所述挡墙140设置于无所述金属层162对应的所述绝缘层161的位置,或设置于所述金属层162对应的所述绝缘层161的位置。
按照配向液流动的方向设置于所述彩膜基板110的所述遮光层111上的第一挡墙143、第二挡墙144、第三挡墙145、复合挡墙146和附加挡墙150,设置为阻挡所述配向液的流动;四个所述挡墙140和一个所述附加挡墙150垂直于所述框胶130涂布的方向设置,四个所述挡墙140的高度沿着配向液的流向递增。第一挡墙143、第二挡墙144、第三挡墙145的材料依次对应红色色阻层、绿色色阻层和蓝色色阻层。由于显示区的红色色阻层、绿色色阻层和蓝色色阻层本来高度就是递增的,以此种方式组成逐个增高的挡墙140,可以跟色阻层116的制程同步形成,制作方便。
各种颜色的所述挡墙140与显示区的对应所述色阻层116的高度相同。这样可以在制作显示区的色阻层116时一同制作出挡墙140所需的色阻层116,减少所需制程。
复合挡墙146为最高的挡墙140,以绿色色阻层和红色色阻层的材料堆叠的方式形成。以色阻层116堆叠成一个最高的挡墙140,有效防止配向液漫过挡墙140流到框胶130区导致框胶130脱落。而且绿色色阻层和红色色阻层均比蓝色色阻层低,组合以后高度可以超过蓝色色阻层,但又不会超太多,避免配向液回流。
当然,复合挡墙146可以由蓝色色阻层和红色色阻层的材料堆叠而成,或者蓝色色阻层和绿色色阻层的材料堆叠而成;或者红色色阻层、绿色色阻层和蓝色色阻层的材料堆叠而成;还可以由色阻层116上堆叠支撑柱117材料的方式形成。
附加挡墙150采用红色色阻层材料制成,所述绝缘层161在复合挡墙146与附加挡墙150之间的位置设置沟槽113,所述沟槽113的宽度小于最高的所述挡墙140与所述附加挡墙150之间的间距。沟槽113的宽度为80μm-280μm。
当然,所述沟槽113的宽度也可以等于于复合挡墙146与所述附加挡墙150之间的间距。沟槽113的宽度为100μm-300μm。
如图5所示,在一实施例中,所述显示面板100包括彩膜基板,所述彩膜基板包括遮光层111和衬底114,所述遮光层111设置在衬底114的非显示区上,所述遮光层111包括凹 槽112;涂布于所述彩膜基板110上的配向层120;设置于所述彩膜基板110上的框胶130,设置为密封所述显示面板100;设置于所述彩膜基板110的所述遮光层111上的多个挡墙140,设置为阻挡所述配向液的流动,多个所述挡墙之间有间距;多个所述挡墙140垂直于所述框胶130涂布的方向设置,多个所述挡墙140的高度沿着配向液的流向递增;其第一个所述挡墙140设置于所述凹槽112中。将第一个所述挡墙140设置于所述凹槽112中,设置比较稳固,防止配向液流到第一个所述挡墙140处将所述挡墙140撞塌。
当然,也可以将多个所述挡墙140设置于多个所述凹槽112中,凹槽112的深度按照配向液流动的方向逐渐减小。
彩膜基板110在显示区包括黑矩阵115、色阻层116和支撑柱117,黑矩阵115设置于衬底114的显示区内,色阻层116设置于黑矩阵115上,支撑柱117设置于色阻层116上,挡墙140包括上层结构141和下层结构142,下层结构142与色阻层116的材料相同,上层结构141与支撑柱117材料相同,挡墙140为单层的下层结构142或下层结构142与上层结构141的堆叠。以此种方式组成逐个增高的挡墙140,采用的都是显示面板100制程中的材料,制作方便,以色阻层116加支撑柱117堆叠成一个高的挡墙140,有效防止配向液漫过挡墙140流到框胶130区导致框胶130脱落。
如图6和图7所示,在一实施例中,多个所述挡墙140平行于所述框胶130涂布的方向A设置,多个所述挡墙140紧密连接,所述挡墙140由下层结构142为色阻层116加上层结构141为支撑柱堆叠而成。
