Description

显示面板的基板、制作方法和显示装置
本申请要求于2019年04月08日提交中国专利局，申请号为CN201910275199.1，申请名称为“一种显示面板的基板、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的基板、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)中，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的基板、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的基板，包括衬底；设置于衬底上的遮光层，所述遮光层位于所述衬底的非显示区内；以及多个挡墙，平行于所述显示面板的框胶涂布的方向设置于所述基板的所述遮光层上，各个所述挡墙之间贴合连接，在所述挡墙设置的方向上任意两个相邻的所述挡墙的高度不同。
本申请还公开了一种显示装置，包括框胶，以及所述显示面板的基板；所述基板包括衬底；设置于衬底上的遮光层，所述遮光层位于所述衬底的非显示区内；以及多个挡墙，平行于所述显示面板的框胶涂布的方向设置于所述基板的所述遮光层上，各个所述挡墙之间贴合连接，在所述挡墙设置的方向上任意两个相邻的所述挡墙的高度不同；所述基板包括彩膜基板和阵列基板；所述彩膜基板和所述阵列基板通过框胶对组。
本申请还公开了一种基板的制作方法，包括步骤：
在衬底的非显示区上设置遮光层；
在所述遮光层上平行于所述显示面板的框胶涂布方向设置多个不同高度的挡墙，各个所述挡墙之间贴合连接。
本申请通过平行于所述显示面板的框胶涂布方向设置不同高度的挡墙，可以使得若挡墙在能挡住配向液的时候各个位置都能挡住，防止配向液漫到框胶处使框胶脱落；若挡墙不能挡住配向液的时候，配向液能固定从较矮的挡墙处溢出，使得配向液可以均匀溢出。

图1为示例性的一种显示面板的剖面结构的示意图，如图1所示，一种显示面板100包括阵列阵列基板160和彩膜基板110，所述彩膜基板110包括衬底114；设置在所述衬底114显示区170内的黑矩阵115；设置在所述衬底114上和黑矩阵115之间的色阻层116；设置在衬底114非显示区180内的遮光层111，设置在所述遮光层111上的挡墙140；以及设置在所述黑矩阵115表面和所述色阻层116表面的配向层120。所述基板包括衬底114；设置在所述衬底114上的金属层162；设置在所述金属层162上的绝缘层161；以及设置在所述绝缘层161上的配向层120。
图2和图3为示例性的一种挡墙设置的示意图，如图2和图3所示，所述挡墙140设置在非显示区180，围绕显示区170设置一圈。
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4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包括框胶130，以及以下所述的基板190；基板190包括彩膜基板110和阵列基板160，彩膜基板110和阵列基板160通过框胶130对组。以下以彩膜基板110为例，进一步阐述本申请的构思。
如图1、图5和图6所示，所述彩膜基板110包括衬底114和遮光层111，所述遮光层111设置于所述衬底114的非显示区180上，设置于所述遮光层111上的多个不同高度的挡墙140，设置为阻挡配向液的流动，多个所述挡墙140平行于所述显示面板100的框胶130涂布的方向A设置，多个所述挡墙140贴合连接；所述挡墙140的高度沿着框胶130的涂布方向A递增。
通过平行于所述显示面板100的框胶130涂布方向设置不同高度的挡墙140，可以使得若挡墙140在能挡住配向液的时候各个位置都能挡住，防止配向液漫到框胶130处使框胶130脱落；若挡墙140不能挡住配向液的时候，配向液能固定从较矮的挡墙140处溢出，使得配向液可以均匀溢出。
具体的，所述彩膜基板110包括黑矩阵115、色阻层116和支撑柱117，所述黑矩阵115 设置于所述衬底114的显示区170内，所述色阻层116设置于所述黑矩阵115上，所述支撑柱117设置于所述黑矩阵115上，所述挡墙140包括上层结构141和下层结构142，所述上层结构141与所述支撑柱117材料相同，所述下层结构142与所述色阻层116的材料相同，所述色阻层116包括不同颜色的色阻，三个所述挡墙140分为一组，一组中所述挡墙140的材料依次对应红色色阻、绿色色阻和蓝色色阻，各色阻之间贴合连接；各个色阻上堆叠所述支撑柱117的高度相同，各色阻上堆叠的所述支撑柱117之间也贴合连接，所述上层结构141的厚度H1小于所述下层结构142的厚度H2，所述上层结构141的宽度L等于所述下层结构142的宽度L，所述厚度H的方向为所述配向液流动的方向，所述宽度L的方向为所述框胶130涂布的方向A；所述下层结构142的高度大于所述上层结构141的高度；所述挡墙140沿着所述框胶130的涂布方向A围绕显示区170设置一圈。当然，所述下层结构142的材料也可以与所述上层结构141的材料相同，所述上层结构141的厚度H1也可以等于所述下层结构142的厚度H2。
以此种方式组成逐个增高的挡墙140，蓝色色阻高于绿色色阻，绿色色阻高于红色色阻，采用的都是显示面板100制程中的材料，制作方便；各色阻之间贴合连接以及各色阻上堆叠的支撑柱117也贴合连接，防止配向液从挡墙140之间流出到框胶130处导致框胶130脱落，因为上层结构141所受的力小，强度要求较低，将厚度H做薄一些，节省材料。
如图7所示，所述挡墙140沿着所述框胶130的涂布方向围绕显示区170设置形成围墙300，所述围墙有多圈300，每圈所述围墙300之间相隔间隙，每一圈所述围墙300内相邻的三个所述挡墙140为一组，分别采用三种不同颜色的色阻材料制成。增加阻挡配向液流动的围墙300，配向液漫过了一圈围墙300还有下一圈围墙300进行阻挡，有效防止配向液流入到框胶130区使框胶130脱落。不同圈的所述围墙300之间的高的挡墙140和低的挡墙140对应位置设置，高的挡墙140对应着低的挡墙140形成的缺口，对漫出的配向液进一步阻挡分流。
如图8所示，在一实施例中，所述显示面板100包括阵列基板160，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，所述金属层162设置于所述衬底114上，所述绝缘层161覆盖所述金属层162设置于衬底114上，多个不同高度的所述挡墙140设置在阵列基板160的绝缘层161上，所述阵列基板160还包括色阻层116，所述色阻层116包括不同颜色的色阻，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是通过将所述挡墙140设置在金属层162的上方以及所述色阻的堆叠来形成不同的高度。
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框胶130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。
当然，也可以额外在挡墙140所在位置的绝缘层161下方设置金属层162来将挡墙140垫高。
如图9所示，在一实施例中，所述显示面板包括彩膜基板110，所述彩膜基板110包括遮光层111、衬底114、框胶130、配向层120和多个挡墙140，所述遮光层111设置在衬底114的非显示区180上，所述遮光层111包括凹槽112；配向层120设置于所述彩膜基板110上；框胶130设置于所述彩膜基板110上，设置为密封所述显示面板100；多个挡墙140设置于所述彩膜基板110的所述遮光层111上，设置为阻挡所述配向液的流动，多个所述挡墙140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。
在彩膜基板110上设置多个挡墙140，将部分挡墙140设置于凹槽112中，使挡墙140的高度按配向液流动的方向逐个递增，当配向液流到挡墙140，会被分步阻挡，有效防止配向液流到框胶130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。
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。以此方式形成不同高度的所述挡墙140，所述凹槽112对所述挡墙140形成一个固定，增大所述挡墙140的受力强度。
如图10所示，作为本申请的另一实施例，公开了一种基板的制作方法，包括步骤：
S1：在衬底的非显示区上设置遮光层；
S2：在所述遮光层上平行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，各个所述挡墙之间贴合连接。
需要说明的是，本方案中涉及到的各步骤的限定，在不影响具体方案实施的前提下，并不认定为对步骤先后顺序做出限定，写在前面的步骤可以是在先执行的，也可以是在后执行的，甚至也可以是同时执行的，只要能实施本方案，都应当视为属于本申请的保护范围。
本申请的技术方案可以广泛用于各种显示面板，如扭曲向列型(Twisted Nematic，TN)显示面板、平面转换型(In-Plane Switching，IPS)显示面板，均可适用上述方案。
以上内容是结合具体的可选的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
