Abstract

Description

阵列基板及显示面板 技术领域
本申请是有关于一种阵列基板及显示面板，特别是关于一种具有阻挡结构的阵列基板及液晶显示面板。
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底，其间夹设一液晶层，一封合胶位于两基底之间，以接合两基底，并将液晶层密封地封合在两基底之间。为使两基底之间的液晶分子形成一定配向，需要在两基底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。
在现有的显示面板中，通过在基底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CF基底上涂布配向层形成液(聚酰亚胺，Polyimide，PI)时涂布到有效显示区域周围的配向层液回流到有效显示区域中。但现行光间隔挡墙的设计大多为平行等高，此种设计容易造成配向层形成液流动性不佳。且在配向层形成液堆积过多时，局部光间隔挡墙会有配向层残液，容易造成显示面板的对向组合的面板间隔(cell gap)偏高，显示面板点灯时会产生边框偏白、亮度不均匀、残痕等不良现像(mura)。另外在对向组合面板的边框四个角落容易积液地方，并无特殊导流设计，在生产过程中，随配向层形成液的涂布，此等角落会有积液越积越高的情形，所以此等角落处越容易有面板间隔(cell gap)偏高的异常问题。

在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度。将理解的是，当例如层、膜、区域或基底的组件被称作“在”另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
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申请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。
本申请的液晶面板可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。
在一些实施例中，本申请的液晶面板可为曲面型显示面板。
图1为范例性的液晶显示面板的横截面结构示意图。液晶显示面板基本结构包括阵列基板100、对向基板200、封合胶以及液晶层。阵列基板100包括一基底101；一阵列结构102，形成于所述基底101上；一配向层103，形成于所述阵列结构102上；以及一阻挡结构104，形成于所述基底101处并大体环绕所述配向层103，其中所述阻挡结构103与所述基底101的一表面构成一段差。如图1所示，配向层103是由配向层形成液(聚酰亚胺，Polyimide，PI)涂布在阵列结构102上所形成。阻挡结构103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、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。
请继续参考图1，阵列基板100中央是有效显示区域，其包括多个像素区域，每一像素区域配置有多个相异色阻，依据显示面板的规格而有不同，如三色色阻、四色色阻或是其它多色色阻的设 计，三色色阻例如红色阻、绿色阻与蓝色阻，四色色阻例如红色阻、绿色阻、蓝色阻与白色阻。各色阻的组合还可以包括黄色阻或其它颜色的色阻。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。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，从而防止在阵列基板上涂布配向层形成液时，涂布到有效显示区域周围的配向层形成液回流到有效显示区域中。常态设计上，各光间隔挡墙是被设计成相同高度，各凹槽是被设计成相同宽度，但为一些必要性设计，光间隔挡墙会被设计成不同高度。为避免配向层形成液溢出，会在阵列结构102外侧两相邻边夹角处外边密集性的配置所述多个光间隔挡墙。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。
