Description

显示装置及其制作方法 技术领域
本公开的实施例涉及一种显示装置及其制作方法。
背景技术
静电放电(Electro-Static discharge，ESD)容易对FIC(Film Integrated Circuit，膜集成电路)产品造成破坏与损伤。对于显示装置而言，驱动芯片(Driver IC)是重要的电路组成部分。实际应用中，由于制作工艺的需要，会在驱动芯片的金属端子区域涂覆一层感光胶(感光胶)。感光胶可以防止金属端子接触到导电体发生短路。但是感光胶是透明的，不易检查其表面平整性，而且对于抗ESD作用不大。
然而在当前，驱动芯片的抗ESD能力已成为衡量移动终端抗ESD能力的重要因素之一。例如，目前市场上驱动芯片的抗ESD的规格在2kV左右，但是由于惯常技术的制约，无法达到移动终端的最低认证标准(一般为6～8kV)，从而导致该类显示产品整体上的性能下降。

附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的至少一个实施例提供了一种制作显示装置的方法，所述方法包括：在显示面板1的设置有暴露连接线图形的边缘区域2上贴附静电屏蔽层3。图1示出了本发明一实施例中提供的一种显示装置的剖面结构以及俯视结构。如图1中的上方的图形所示，在显示面板1的边缘区域2中包括设置连接线图形的第一区域21和不设置连接线图形的第二区域22，静电屏蔽层3包括绝缘材料区域31和导电材料区域32，所述绝缘材料区域31面向显示面板1并接触第一区域21，所述导电材料区域32面向显示面板1并接触第二区域22。在边缘区域2中，第一区域21与第二区域22之间的边界可根据实际应用需求进行设置。静电屏蔽层3贴附在显示面板1的边缘区域2的第一区域21上，如图1下方的图形所示。图1下方的图形为沿图1中的A-A’线的剖视图。该绝缘材料区域31与第一区域21相对并接触，该导电材料区域32与第二区域22相对并接触。例如，可以采用静电屏蔽层3覆盖在边缘区域2上方，两者之间采用胶体固定。
本公开的实施例通过在显示面板1的形成有暴露连接线图形的边缘区域2上贴附静电屏蔽层3，有效屏蔽静电荷和静电场对形成在第一区域21中的 连接线图形的影响。而且，贴附的静电屏蔽层可以代替在显示面板上制作的感光胶，因而相对于设置感光胶的显示面板，可以在不增加工艺流程的情况下提高边缘的芯片的连接线的抗ESD能力。另外，相对于感光胶而言，形成材料中含有金属的静电屏蔽层是非透明的，更容易检查贴附情况，而且也不会产生表面平整性的缺陷，有利于产品良率和性能上的提升。
需要说明的是，本公开实施例通过在显示面板1的边缘区域2表面设置静电屏蔽层3就可以将到达该表面的静电荷与静电场阻挡在显示面板的外面。若持续发生ESD放电现象，则静电荷可能存储在该静电屏蔽层3上，从而使静电屏蔽层3成为一个带电体，也就是说，在持续ESD放电的情况下，静电屏蔽层3成为带电体并可能对显示面板1上的其他部件造成损伤。
如图2所示，在本公开的一个实施例中，导电材料区域32还可以接触边缘区域内接地的导电触点CC(图2中所示为银质的导电触点)，以释放聚集在静电屏蔽层3上的电荷。通过将导电材料区域32连接导电触点，使聚集在其表面的静电荷及时传输到导电触点CC并被释放掉，从而进一步提升显示面板的抗ESD能力。
本领域技术人员也可以在其他位置处为静电屏蔽层单独设置接地的导体连接结构，以将静电荷及时释放。
本公开实施例中，在将静电屏蔽层3的表面上的导电材料区域32贴附至边缘区域2的第二区域22的工艺中，需要保证该导电材料区域32不能接触连接线图形。为此，在本公开的一个实施例中，所述边缘区域内设置有至少一个连接线图形，上述在显示面板1的形成有暴露连接线图形的边缘区域2上贴附静电屏蔽层3，可以包括以下步骤：
分别在所述至少一个连接线图形的每一个上贴附绝缘材料层；
在边缘区域2上贴附导电材料层，以形成包括绝缘材料区域31和导电材料区域32的静电屏蔽层3，如图3所示。
在本公开的实施例中，通过两个步骤形成静电屏蔽层3，先于导电材料层贴附的绝缘材料层可以遮盖连接线图形暴露的表面，使导电材料层与连接线图形无法接触，从而避免在贴附导电材料层的过程中导电材料层接触连接线图形形成短路，可以有效提高对位的准确度。
图4示出了根据本公开另一实施例的静电屏蔽层的设置方式。在该实施 例中，静电屏蔽层3包括对应于整个边缘区域2的绝缘材料层31，以及在导电材料区域内贴附在该绝缘材料层31上的导电材料层32。在根据该实施例的方法中，预先在绝缘材料层31上的导电材料区域内贴附导电材料层32以形成静电屏蔽层3，然后再将静电屏蔽层3通过对位的方式贴附在边缘区域2上。基于此，相比于图3所示的贴附方式，可以减少导电材料的使用量，导电材料的实际使用量可以减少一半以上，因而有助于成本的降低。
需要说明的是，本公开实施例中导电材料层可由金属箔片制成。可选地，上述金属箔片为铝材质；可选地，上述金属箔片可以为一层，也可以为多层。绝缘材料层由绝缘布制成。
在本公开的一个实施例中，金属箔片以及绝缘布之间可以采用黏胶完成贴附过程，从而简化工艺流程。
图5是本公开再一实施例中提供的一种显示面板在边缘区域内的剖面图。参见图5，在该实施例中，显示面板内形成有公共电极层，但公共电极层均位于边缘区域之外，因此在图5所示的边缘区域部分没有示出。在图5中，在显示面板边缘区域基板的平坦层43上分别形成靠近显示面板显示区域的源漏金属层45和远离显示面板显示区域的平坦化绝缘膜层44，在源漏金属层45上形成具有连接线图形的第一区域作为导体金属层41，例如像素电极层；在平坦化绝缘膜层44形成不具有连接线图形的第二区域作为绝缘层42，例如钝化层。在此之后，在其上可贴附静电屏蔽层3。由此，因为去除了通常由ITO(氧化铟锡)材料形成的公共电极层，所以显示面板边缘处由上方接触像素电极层的接触电阻可以大大降低，有利于提升抗ESD的效果。
基于同样的发明构思，本公开的至少一个实施例提供一种显示装置，该显示装置可以为：显示面板、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。如图2所示，该显示装置包括显示面板1；所述显示面板1的形成有暴露连接线图形的边缘区域2上贴附有静电屏蔽层3；其中，在显示面板1的边缘区域2中包括设置连接线图形的第一区域21和不设置连接线图形的第二区域22，静电屏蔽层3包括绝缘材料区域31和导电材料区域32，所述绝缘材料区域31面向显示面板1并接触第一区域21，所述导电材料区域32面向显示面板1并接触第二区域22。
本公开的实施例通过在显示面板暴露有连接线图形的边缘区域上贴附静电屏蔽层，有效阻挡静电荷和静电场对边缘区域内连接线图形的影响。而且，贴附的静电屏蔽层可以代替在显示面板上制作的感光胶，因而可以在不增加工艺流程的情况下提高边缘的芯片的连接线上设置感光胶的显示面板的抗ESD能力。另外，形成材料包括金属的静电屏蔽层是非透明的，相比感光胶更容易检查贴附情况，而且也不会产生表面平整性的缺陷，有利于产品良率和性能上的提升。
在本公开的一个实施例提供的显示面板中，可使所述导电材料区域电性连通边缘区域内接地的导电触点，以进一步提升显示面板的抗ESD能力。
在本公开的一个实施例提供的显示面板中，所述第一区域内设置有至少一个连接线图形，所述静电屏蔽层包括至少一个绝缘材料层和导电材料层；其中，所述绝缘材料层分别贴附在所述至少一个连接线图形的每一个上；所述导电材料层贴附在所述边缘区域上并覆盖所述至少一个绝缘材料层。基于此，可以避免在贴附导电材料层的过程中短路连接线图形，有效提高对位的准确度。
在本公开的一个实施例提供的显示面板中，所述静电屏蔽层包括绝缘材料层，以及在所述导电材料区域内贴附在所述绝缘材料层上的导电材料层。从而，可以减少导电材料的使用量，因而有助于成本的降低。
在本公开的一个实施例提供的显示面板中，所述导电材料层由金属箔片构成；可选地，上述金属箔片为铝材质；可选地，上述金属箔片可以为一层，也可以为多层。绝缘材料层由绝缘布制成。
在本公开的一个实施例提供的显示面板中，金属箔片以及绝缘布之间可以采用黏胶完成贴附过程，从而简化工艺流程。
在本公开的一个实施例提供的显示面板中，所述显示面板内具有公共电极层；所述公共电极层均位于所述边缘区域之外。从而，显示面板边缘处由上方接触像素电极层的接触电阻可以大大降低，有利于提升抗ESD的效果。
在本公开的实施例中，说明了大量具体细节。然而，能够理解，本公开的实施例可以在没有这些具体细节的情况下实践。在一些实施例中，并未详细示出公知的方法、结构和技术，以便不模糊对本公开的理解。
需要说明的是，在本公开的实施例中，术语“上”、“下”等指示的方 位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限定。除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应作广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
还需要说明的是，在本公开中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限定的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
本申请要求于2016年5月18日递交的中国专利申请No.201610331525.2的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
