Description

阵列基板及其应用的显示面板 技术领域
本申请是有关于一种阵列基板及其应用的显示面板，特别是关于一种具有阻挡结构的显示面板面板及液晶显示面板。
背景技术
随着科技进步，具有省电、无幅射、体积小、低耗电量、平面直角、高分辨率、画质稳定等多项优势的液晶显示器，尤其是现今各式信息产品如：手机、笔记本电脑、数字相机、PDA、液晶屏幕等产品越来越普及，也使得液晶显示器(Liquid Crystal Display，LCD)的需求量大大提升。目前被广泛应用的液晶显示器通常具有两基板，其间夹设液晶层，封合胶位于两基板之间，以接合两基板，并将液晶层密封地封合在两基板之间。为使两基板之间的液晶分子形成一定配向，需要在两基板的表面分别形成配向层(Alignment Layer或Orientation Layer)，通过在配向层上形成配向槽来构成配向层。配向层形成后，再形成封合胶接合两基底。
配向层的涂布方式目前大致有两种，即印刷方式和涂布方式。印刷方式工艺复杂，主要应用于小尺寸面板。涂布方式涂布效率高，适用于大尺寸面板。
在显示面板中，通过在彩色滤光层(Color Filter，CF)基板的周边区域中设置数道光间隔挡墙(Dummy PS Wall)及数条沟槽，从而防止在彩色滤光层基板上涂布配向层形成液(聚酰亚胺，Polyimide，PI)时，配向层形成液从有效显示区域周围回流到有效显示区域中。但是在主动开关阵列(Thin Film Transistor，TFT)基板侧就没法设计挡墙来防止配向层形成液回流，特别是在显示面板布线区的扇出区线路(fanout)交接的位置。由于显示面板扇出区的设计限制，传输线路配合各交接部位会形一个倒三角的区域，在这个位置很容易发生配向层形成液回流堆积。目前在阵列基板侧都是通过调整涂布机的控制配向层形成液的涂布精度，而且以涂布方式中的喷涂方式居多。但是随着市场对大尺寸窄边框产品的需求提升，喷涂方式的涂布机，较不易调整出窄边框产品需求的涂布精度。

另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种阵列基板及显示面板，其具体实施方式、结构、特征及其功效，详细说明如后。
本申请的显示面板例如为液晶显示面板、OLED显示面板、QLED显示面板或其他显示面板。以液晶显示面板为例，液晶显示面板包括第一基底及第二基底与形成于两基底之间的液晶层，第一基底及第二基底可例如为主动阵列开关(Thin Film Transistor，TFT)基底、彩色滤光层(Color Filter，CF)基底。然不限于此，在一些实施例中，本申请的主动阵列开关及彩色滤光层亦可形成于同一基底上。液晶显示面板基本结构包括主动开关阵列(Thin Film Transistor，TFT)基板、彩色滤光层(Color Filter，CF)基板、封合胶以及液晶层。
在一些实施例中，本申请的显示面板可为曲面型显示面板。

阵列基板100包括第一基底101；阵列结构102，形成于所述第一基底101上，所述阵列结构102包括信号线、主动开关与像素单元设置在所述第一基底101的显示区，所述多个像素单元分别耦接于所述多个主动开关，所述多个主动开关电性耦接所述多条信号线，所述多条信号线包括多条栅极线与多条源极线；第一配向层103，形成于所述阵列结构102上；彩色滤光层基板200包括第二基底201；彩色滤光层202，形成于所述第二基底201上，第二配向层203，形成于所述彩色滤光层202上。多个驱动单元106，设置于所述第一基底101的布线区105，电性耦接所述多条信号线；多条连接导线107，间隔配置于所述布线区105并电性连接于所述多个驱动单元106之间。在一些实施例中，阻挡结构204，形成于所述第二基底201处并大体环绕所述第二配向层203。所述阻挡结构204包括数种不同的结构，依据不同的需求可以设计如：凹槽、光间隔物(Photo Spacer，PS)形成的光间隔挡墙(Dummy PS Wall)、非显示区域色阻挡墙，或是此三种组件之中至少其一者所组成的结构设计。所述的非显示区域色阻挡墙的材料为红色阻、蓝色阻或者绿色阻。其中，所述非显示区域色阻挡墙，在加工时先进行红、蓝或者绿色阻涂布，所述光间隔挡墙进行光间隔挡墙色阻涂布同时对色阻进行曝光。光间隔挡墙是配置在非显示区域色阻挡墙上，依据设计需求，可以形成数层光间隔挡墙。光间隔挡墙高度及凹槽的宽度设计上考虑了由于机台的精度误差导致的多吐出配向层形成液的部分，通过计算准确定义光间隔挡墙及凹槽的铺设尺寸。因此，通过在彩色滤光层基板200的周边区域中设置阻挡结构204，从而防止在彩色滤光层基板200上涂布配向层形成液(聚酰亚胺，Polyimide，PI)时，配向层形成液从有效显示区域周围回流到有效显示区域中。
但在主动开关阵列基板侧就没法设计挡墙来防止配向层形成液回流，特别是在布线区(fanout)105交接的位置。如图1b与图1c所示。由于布线区105的设计限制，传输线路107配合各交接部位会形成一个外宽内窄的三角区域(虚方框)，在这个位置很容易发生配向层形成液112回流 堆积(虚圆框)。以上所述，仅是以液晶显示面板其中一结构为例来作一说明，但本申请的应用范围并不仅限于此，其更可应用于各类型的液晶显示面板。
图2为显示依据本申请的方法，一实施例应用于阵列基板的局部布线区示意图。请配合图1a及图1b以利于理解。如图2所示，一种阵列基板100，包括：第一基底101，包括显示区104及其***的布线区105，多条信号线、多个主动开关和多个像素单元设置在所述第一基底101的显示区104，所述多个像素单元分别耦接于所述多个主动开关，所述多个主动开关电性耦接所述多条信号线，所述多条信号线包括多条栅极线与多条源极线；多个驱动单元106，设置于所述第一基底101的边缘，电性耦接所述多条信号线；多个连接导线107，间隔设置于所述多个驱动单元106之间，且位于所述布线区105，与所述多个驱动单元106电性连接；其中，所述多条连接导线107内形成有多个导流沟槽108，所述多个导流沟槽108为多个线条形状排列组成，所述多个导流沟槽108的沟槽方向大致为所述第一基底101内朝向所述第一基底101外缘的方向延伸形成。
