Description

显示面板和显示装置
本申请要求于2018年9月14日提交中国专利局、申请号为CN 201821514195.1、发明名称为“一种显示面板和显示装置”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。
随着科技的发展和进步，液晶显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶显示面板及背光模组(Backlight Module)。液晶显示面板包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)、薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFTSubstrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(LiquidCrystal，LC)。
当光束通过这层液晶时，液晶本身会排排站立或扭转呈不规则状，因而阻隔或使光束顺利通过。大多数液晶都属于有机复合物，由长棒状的分子构成。在自然状态下，这些棒状分子的长轴大致平行。将液晶倒入一个经精良加工的开槽平面，液晶分子会顺着槽排列，所以假如那些槽平行，则各分子也是平行的。液晶是一种介于晶体状态和液态状态之间的中间物质。它兼有液体和晶体的某些特点，表现出一些独特的性质。在框胶将两层基板封闭之后，液晶会进入框胶中使得发生液晶穿刺的风险变高。

窄边框显示面板要求非显示区域180宽度减小，而该区域宽度减小后，显示区域170的液晶140进入框胶150即发生液晶140穿刺的风险将变高。
下面结合附图和较佳的实施例对本申请作进一步说明。
如图1至图3所示，本申请实施例公布了一种显示面板100，包括：第一基板110；第二基板120；液晶层140，位于第一基板110与第二基板120之间，液晶层140包括液晶141；框胶150，位于第一基板和110第二基板120的边缘，粘合第一基板110和第二基板120；挡墙130，位于液晶层140和框胶150之间，形成一个包围圈，阻挡液晶141进入框胶；挡墙130每条边的长度大于每条边两端点之间的直线距离；挡墙130可以设置一圈或多圈，挡墙130的宽度和高度可调节；挡墙130尽可能靠近框胶150远离显示区域170，可只在边框较窄的边制作挡墙130，而在边框较宽的边留出开口，以增加液晶140区域。其中，第一基板110为阵列基板，第二基板120为彩膜基板。
本方案中，在非显示区域180和框胶150之间增加挡墙130可以限制液晶141的活动范围，挡墙130每条边的长度大于每条边两端点之间的直线距离，增加挡墙130的长度，从而增加挡墙130的上表面积，在防止发生液晶141穿刺时增加挡墙130对显示面板100边缘部分的支撑力。
在一个实施例中，挡墙130形状为锯齿状。
本方案中，相比于直线型的挡墙130，锯齿状的挡墙130可以使得液晶141进入折角后产生回流，进一步避免液晶141穿刺。
在一个实施例中，挡墙130形成的包围圈内侧尖角处进行倒圆角处理。
本方案中，将挡墙130形成的包围圈内侧尖角进行倒圆角处理，使尖角变成圆弧拐角131，增大受力面积，减小液晶141对挡墙130下凹的尖角处的压力，防止液晶141刺穿挡墙130。
在一个实施例中，挡墙130形成的包围圈外侧尖角处进行倒圆角处理。
本方案中，在制作窄边框的时候挡墙130与框胶150会十分接近，将挡墙130形成的包围圈外侧尖角处进行倒圆角处理，防止尖角对框胶150产生损伤从而导致胶合不稳固的事情发生。
在一个实施例中，挡墙130的所有尖角进行倒圆角处理。
本方案中，在生产过程中，尖角处难以完整的保留，会产生缺陷，将挡墙130的所有尖角进行倒圆角处理。
在一个实施例中，挡墙130包括矩形拐角132，挡墙130的相邻两条边之间以矩形拐角132连接。
本方案中，在夹角处容易产生集中的压力，使得液晶141容易刺穿挡墙130，现以矩形拐角132来替代夹角，增大拐角的受力面，增大拐角的受力强度，防止液晶141在相邻两条边的连接处发生刺穿现象。

本方案中，在夹角处容易产生集中的压力，使得液晶141容易刺穿挡墙130，现以圆弧拐角131来替代夹角，对液晶141产生的压力进行分散，防止液晶141在每条边的连接处发生刺穿现象。
在一个实施例中，显示面板100包括膜柱160，挡墙130的制程在进行膜柱160的制程中同时完成，挡墙130和膜柱160使用相同的材料。
本方案中，在制造膜柱160的同时将挡墙130制造出来，无需新增加制程，节省制造工序。
作为本申请的另一实施例，如图1至图3所示，公开了一种显示面板100，包括：第一基板110；第二基板120；液晶层140，位于第一基板110与第二基板120之间，液晶层140包括液晶141；框胶150，位于第一基板和110第二基板120的边缘，粘合第一基板110和第二基板120；挡墙130，位于液晶层140和框胶150之间，形成一个包围圈，阻挡液晶141进入框胶；挡墙130每条边的长度大于每条边两端点之间的直线距离；挡墙130形状为锯齿状；挡墙130包括矩形拐角132，挡墙130的相邻两条边之间以矩形拐角132连接；挡墙130的制程在进行膜柱160的制程中同时完成。
相对于一般的显示面板100，该申请增加挡墙130可以限制液晶141的活动范围，挡墙130每条边的长度大于每条边两端点之间的直线距离，增加挡墙130的长度，从而增加挡墙130的上表面积，在防止发生液晶141穿刺时增加挡墙130对显示面板100边缘部分的支撑力。相比于直线型的挡墙130，锯齿状的挡墙130可以使得液晶141进入折角后产生回流，进一步避免液晶141穿刺。在制造膜柱160的同时将挡墙130制造出来。
