Description

一种显示面板及其制作方法 【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及其制作方法。
【背景技术】
显示器一般都基于主动开关进行控制，具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，主要包括液晶显示器、OLED(Organic Light-Emitting Diode)显示器、QLED(Quantum Dot Light Emitting Diodes)显示器、等离子显示器等、从外观结构来看，既有平面型显示器、也有曲面型显示器。
对于液晶显示器，包括液晶面板及背光模组(BacklightModule)两大部分，液晶显示器的工作原理是在两片平行的玻璃基板当中放置液晶分子，并在两片玻璃基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
对于OLED显示器，采用机发光二极管自发光来进行显示，具有自发光、广视角、几乎无穷高的对比度、较低耗电、极高反应速度等优点。
QLED显示器结构与OLED技术非常相似，主要区别在于QLED的发光中心由量子点(Quantum dots)物质构成。其结构是两侧电子(Electron)和空穴(Hole)在量子点层中汇聚后形成光子(Exciton)，并且通过光子的重组发光。
随着市场的进化，人们越来越倾向于显示器的窄边框化，使得形成配向层的PI(Polyimide，聚酰亚胺)液容易在显示区和框胶区的设置比较困难，非常影响显示面板的显示效果和显示品质。

在图中，结构相似的单元是以相同标号表示。
如图1所示，申请人设计了一款未公开的显示面板，显示面板包括第一基板11和第二基板，第一基板11和基板上设有配向层14，显示面板包括显示区30和框胶区31，第一基板11和第二基板之间设有间隔单元32(photo spacer，PS)，间隔单元32设在显示区30和框胶内侧边缘之间；在黑色矩阵层13上设置配向层14是通过在其表面涂布一层聚酰亚胺(Polyimide，PI)液，PI液33是用来形成预倾角以利于液晶的在显示时具有固定倒向，待PI液33进过摩擦(rubbing)的动作，让PI的表面分子均匀排列形成配向层14，在涂布PI液33时由于显示面板的边框位置会设置框胶，然而PI不能涂布超过框胶的位置，否则会出现框胶出现剥落或脱落，从而导致显示面板的显示异常，间隔单元32能够有效的对涂布的PI液33进行阻挡，使得PI液33回流堆积在显示区30附近，有效的避免框胶出现剥落或脱落，从而导致显示面板的显示异常的情况发生。
进一步的间隔单元32会设置一道或几道来形成PI液33的挡墙，挡墙的高度是PI液33厚度的10倍以上，能够对PI液33进行有效的阻挡，有效的避免PI液33进入框胶区31，从而有效的保证框胶的正常使用，进一步的提高显示面板的显示效果以及显示品质。
申请人进一步研究发现，由于间隔单元32的突起式的设置形成PI也的挡墙，会使得PI液33回流堆积在显示区30的附近，固化后会导致配向层14厚度增加，影响液晶层在显示时具有固定倒向，使得显示面板出现显示异常。

在上述实施例中，以液晶面板为例，液晶面板包括阵列基板和彩膜基板(CF)，所述阵列基板与彩膜基板相对设置，所述阵列基板与彩膜基板之间设有液晶和间隔单元32，所述阵列基板上设有主动开关20，主动开关20例如为薄膜晶体管(TFT)，彩膜基板上设有彩色滤光层15，彩色滤光层15及主动开关20可形成于同一基板上。
参考图7本申请的实施例申请了一种显示面板的制作方法，包括：
S71：提供一第一基板和第二基板；
S72：在所述第一基板上设置黑色矩阵层；
S73：采用多色调光罩制程在所述黑色矩阵层上获取至少一条沟槽；
S74：在所述黑色矩阵层和所述第二基板上设置配向层；
S75：在所述第一基板上设置彩色滤光层；
S76：在所述第一基板及所述第二基板之间设置液晶层；
S77：在所述第二基板上设置主动开关；
S78：在所述第一基板或所述第二基板上对应所述沟槽的位置设置遮光层，所述遮光层在所述基板的正投影区域完全覆盖所述沟槽在所述基板的正投影区域。
通过在黑色矩阵层13上设置至少一条沟槽131，使得在涂布PI液时，间隔单元形成的挡墙会使得PI液回流，回流的PI液进入沟槽131内，将沟槽131进行填平，有效的避免PI液的堆积，使得PI液的涂布更加的均匀，PI液形成的配向层14厚度比较均匀一致，有效的降低配向层14对液晶层16的影响，有效的避免显示面板点亮时出现mura现象，即显示面板的亮度不均匀,以及造成各种痕迹的现象，使得显示面板的具有更好的显示效果，从而有效的提高显示面板的显示品质。
在上述实施例中，显示面板包括液晶面板、OLED(Organic Light-Emitting Diode)面板、QLED(Quantum Dot Light Emitting Diodes)面板、等离子面板、平面型面板、曲面型面板等，在此不做限定。
参考图8，本实施方式申请一种显示装置100。该显示装置100包括控制部件200，以及本申请所述的显示面板300，以上以显示面板为例进行详细说明，需要说明的是，以上对显示面板结构的描述同样适用于本申请实施例的显示装置中。其中，当本申请实施例的显示装置为液晶显示器时，液晶显示器包括有背光模组，背光模组可作为光源，用于供应充足的亮度与分布均匀的光源，本实施例的背光模组可以为前光式，也可以为背光式，需要说明的是，本实施例 的背光模组并不限于此。
以上内容是结合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。
