Description

一种显示屏 技术领域
本申请涉及显示技术领域，尤其涉及一种显示屏。
背景技术
PMOLED(英文全称：Passive matrix Organic Light-Emitting Diode，中文名称：被动式有机电激发光二极管)是有机电激发光二极管的一种，具有自发光、对比度高、厚度薄、视角广、反应速度快、制作过程较简单等特点，被越来越多地应用到各个显示以及照明领域。
通常，针对PMOLED显示屏而言，在制作PMOLED显示屏的过程中，需要使用绝缘胶对显示屏引线区中的正极引线以及负极引线进行绝缘，以保证在对引线区通电后，显示屏可以正常发光显示。具体地，可以将绝缘胶均匀地涂抹在引线区的正极引线以及负极引线上，使得引线区上覆盖有一整块的绝缘层，进而实现对正极引线以及负极引线的绝缘。
然而，在实际应用中，针对一整块的绝缘层而言，绝缘层的一部分区域脱落后，很容易导致整块绝缘层脱落，在整块绝缘层脱落的情况下，引线区的正极引线以及负极引线很容易相互接触，这样，在对引线区通电后，正极引线以及负极引线很容易被损坏并出现电腐蚀的现象，造成显示屏显示异常，产品良率较低。
实用新型内容
本申请的主要目的是提供一种显示屏，旨在解决现有技术中，使用绝缘胶对显示屏引线区中的引线绝缘后，在绝缘层脱离时，容易造成引线区的引线电腐蚀，导致显示屏显示异常，产品良率较低的问题。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图示出的结构获得其他的附图。
图1为现有技术中的一种显示屏的结构示意图；
图2为本申请实施例提供的一种显示屏的结构示意图；
图3为本申请实施例提供的另一种显示屏的结构示意图。
本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
现有技术中，在制作PMOLED显示屏的过程中，通常可以使用绝缘胶对显示屏引线区中的引线(包括正极引线以及负极引线)进行绝缘处理。在使用绝缘胶对引线区的引线进行绝缘处理后，引线区的引线上会覆盖有绝缘胶形成的一整块绝缘层。
如图1所示，显示屏包含引线区以及非引线区(图1中未示出非引线区)，所述引线区中可以包含正极引线11以及负极引线12。针对所述引线区而言，在使用绝缘胶对所述引线区进行绝缘处理后，所述引线区的正极引线11以及负极引线12上覆盖有一整块的绝缘层13(图1中的灰色部分)，绝缘层13可以起到对正极引线11以及负极引线12绝缘的作用。
在实际应用中，绝缘层13会不可避免的出现局部脱落的现象，此时，由于绝缘层13是一整块的绝缘层，因此，很容易造成整块绝缘层的脱落。在绝缘层13脱落后，正极引线11以及负极引线12在未被绝缘的情况下，很容易相互接触。这样，在对正极引线11以及负极引线12进行通电时(例如，对显示屏进行老炼处理时通电)，由于正极引线11以及负极引线12相互接触，容易造成正极引线11以及负极引线12的电腐蚀，进而导致显示屏显示异常，产品良率较低。
为了解决上述问题，本申请实施例提供一种显示屏，包括：引线区，其中：所述引线区包含第一引线区以及第二引线区；所述第一引线区上覆盖有 第一绝缘层，所述第二引线区上覆盖有第二绝缘层，所述第一绝缘层与所述第二绝缘层互不接触。本申请实施例提供的技术方案，显示屏引线区中的正极引线以及负极引线可以分别覆盖绝缘层，且绝缘层之间互不接触，这样，在正极引线或负极引线上覆盖的绝缘层脱落时，不会影响其他绝缘层脱落，进而避免正极引线与负极引线相互接触，相较于现有技术而言，可以有效降低正极引线以及负极引线电腐蚀的几率，提高产品的良率。
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，本申请实施例提供的显示屏，可以是PMOLED显示屏，也可以是其他使用绝缘胶对引线区中的引线进行绝缘的显示屏，不做具体限定。本申请实施例可以以PMOLED显示屏为例进行说明。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图2为本申请实施例提供的一种显示屏的结构示意图。所述显示屏如下所述。
如图2所示，所述显示屏可以包括引线区以及非引线区(图2中未示出非引线区)，其中，所述引线区可以包含第一引线区21以及第二引线区22，所述非引线区可以包含所述显示屏的有效显示区。
需要说明的是，第一引线区21可以是所述引线区中正极引线所在的区域，第二引线区22可以是所述引线区中负极引线所在的区域；或者，第一引线区21可以是所述引线区中负极引线所在的区域，第二引线区22是所述引线区中正极引线所在的区域，本申请实施例不做具体限定。图2中可以以第一引线区21是所述引线区中正极引线所在的区域，以及第二引线区22是所述引线区中负极引线所在的区域为例进行说明。
本申请实施例中，第一引线区21上可以覆盖有第一绝缘层23(图2中深色阴影部分)，第二引线区22上可以覆盖有第二绝缘层24(图2中浅色阴影部分)，其中，第一绝缘层23与第二绝缘层24之间互不接触。也就是说，用于对所述引线区中正极引线以及负极引线进行绝缘的绝缘层不再是一整块，而是可以 按照引线的类型(即正极引线以及负极引线)使用互不接触的多个绝缘层分别对引线进行绝缘。
相对于现有技术而言，通过将用于对所述引线区中的正极引线以及负极引线进行绝缘的绝缘层分块处理(即分为第一绝缘层23以及第二绝缘层24)，分块后的绝缘层互不接触，并使用分块后的绝缘层分别对正极引线以及负极引线进行绝缘，这样，可以在其中一块绝缘层脱落时，不影响其他绝缘层脱落，进而保证所述正极引线以及所述负极引线不会由于绝缘层的脱落相互接触，极大降低了引线被电腐蚀的几率，提高产品的良率。
例如，图2中，第一绝缘层23脱落掉后，第二绝缘层24不会脱落，这样，由于第二绝缘层24没有脱落，即使第一引线区21中的引线未被绝缘，第一引线区21中的引线也不会与第二引线区22中的引线相接触，从而可以避免第一引线区21中的引线被电腐蚀，提高产品的良率。
需要说明的是，在实际应用中，所述引线区包含的所述第一引线区的个数可以是一个，也可以是多个(多个所述第一引线区可以是互不接触的)，所述引线区包含的所述第二引线区的个数可以是一个，也可以是多个(多个所述第二引线区可以是互不接触的)，那么，为了有效避免所述引线区中的引线电腐蚀，在本申请实施例中：
针对所述第一引线区，若所述引线区包含一个所述第一引线区，则所述第一引线区上可以覆盖有所述第一绝缘层；若所述引线区包含多个所述第一引线区，则每一个所述第一引线区上可以分别覆盖有所述第一绝缘层。
针对所述第二引线区，若所述引线区包含一个所述第二引线区，则所述第二引线区上可以覆盖有所述第二绝缘层；若所述引线区包含多个所述第二引线区，则每一个所述第二引线区上可以分别覆盖有所述第二绝缘层。
例如，图2中第一引线区21的个数是一个，第二引线区22的个数是两个，那么，第一引线区21上可以覆盖有第一绝缘层23，每一个第二引线区22上分别覆盖有第二绝缘层24。
还需要说明的是，在实际应用中，在引线区上覆盖绝缘层时，针对同一个引线区，其上覆盖的绝缘层可以包含多个绝缘块，两个相邻的绝缘块之间可以相互接触，但是，其中一个绝缘块脱落并不会影响其相邻的绝缘块，这样，针对同一个引线区而言，可以更为有效地对其中的引线进行绝缘。
如图3所示，图3中第一绝缘层23可以包含两个相互接触的绝缘块231和绝缘块232，其中，绝缘块231以及绝缘块232的大小相同，并且，对称覆盖在第一引线区21上，对第一引线区21中的引线起绝缘作用。其中，在绝缘块231脱落时，并不影响绝缘块232，这样，可以有效地对第一引线区21中的引线进行绝缘。
本申请实施例中，第一绝缘层23的形状可以与第一引线区21的形状相同，第二绝缘层24的形状可以与第二引线区22的形状相同，这样，一方面可以保证第一绝缘层23与第二绝缘层24之间互不接触，另一方面还可以保证第一绝缘层23能够覆盖在第一引线区21上，并对第一引线区21的引线进行绝缘，第二绝缘层24能够覆盖在第二引线区22上，并对第二引线区22的引线进行绝缘。
本申请实施例中，第一绝缘层23与第二绝缘层24之间可以存在间隙，所述间隙可以不小于0.01毫米(具体可以根据实际情况确定，本申请实施例不做具体限定)，这样，可以有效保证第一绝缘层23与第二绝缘层24之间互不接触。
第一绝缘层23使用的绝缘胶的可以是有机绝缘胶(例如PI胶)，也可以是无机绝缘胶(例如氧化硅胶)，第二绝缘层24使用的绝缘胶可以是有机绝缘胶，也可以是无机绝缘胶，不做具体限定。作为一种优选地方式，第一绝缘层23以及第二绝缘层24所使用的绝缘胶可以均为PI胶。
第一绝缘层23的厚度可以与第二绝缘层24的厚度相同。其中，第一绝缘层23的厚度(即第二绝缘层24的厚度)不宜过大，也不宜过小，原因是：若第一绝缘层23的厚度过小，则第一绝缘层23容易断裂；若第一绝缘层23的厚度过大，则不易对所述显示屏进行加工。
本申请实施例中，作为一种优选地方式，第一绝缘层23的厚度范围可以在3.1微米至3.9微米之间，第二绝缘层24的厚度范围也可以在3.1微米至3.9微米之间。考虑实际应用，第一绝缘层23以及第二绝缘层24的厚度可以均为3.2μm±0.1μm。
本申请实施例提供的显示屏，包括：引线区，其中：所述引线区包含第一引线区以及第二引线区；所述第一引线区上覆盖有第一绝缘层，所述第二引线区上覆盖有第二绝缘层，所述第一绝缘层与所述第二绝缘层互不接触。本申请实施例提供的技术方案，显示屏引线区中的正极引线以及负极引线可 以分别覆盖绝缘层，且绝缘层之间互不接触，这样，在正极引线或负极引线上覆盖的绝缘层脱落时，不会影响其他绝缘层脱落，进而避免正极引线与负极引线相互接触，相较于现有技术而言，可以有效降低正极引线以及负极引线电腐蚀的几率，提高产品的良率。
本领域的技术人员应明白，尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
