上述说明仅是本公开技术方案的概述,为了能够更清楚了解本公开的技术手段,而可依照说明书的内容予以实施,并且为了让本公开的上述和其它目的、特征和优点能够更明显易懂,以下列举本公开的具体实施方式。
附图说明
通过阅读下文示例性实施方式的详细描述,各种其他的优点和益处对于本领域普通技术人员将变得清楚明了。附图仅用于示出示例性实施方式的目的,而并不认为是对本公开的限制。而且在整个附图中,用相同的参考符号表示相同的部件。在附图中:
图1示出了现有的封装胶的局部剖视图;
图2示出了根据本公开的实施例的一种显示面板的制作方法的流程图;
图3示出了根据本公开的实施例的丝网的结构示意图;
图4示出了本公开的实施例的封装胶的局部剖视图。
具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示,若沿着切割线121切割出窄边框的显示面板,则封装胶在封装区的拐角位置的部分处极易发生裂纹,从而引起封装信赖性测试失败,导致显示面板的切割良率难以控制。
图2示出了根据本公开的实施例的一种显示面板的制作方法的流程图。
下面以丝网印刷为例来描述形成封装胶的过程,本领域的技术人员应了解还可以采用其它方式来形成封装胶。
在本公开实施例中,显示母板包括至少一个显示面板,每个显示面板具有显示区和围绕所述显示区的封装区。
如图2所示,在步骤201中,在所述封装区形成封装胶。所述封装胶在所述封装区的拐角位置的部分处具有朝向所述显示区的凹陷。
首先,制作具有拐角位置向内凹陷的丝网,其中,丝网的图案与显示母板中各个显示面板的大小和位置相对应。所述显示面板可以为OLED面板。所述OLED面板包括主动矩阵有机发光二极管(Active Matrix/Organic Light Emitting Diode,简称AMOLED)面板。
图3示出了根据本公开的实施例的丝网的结构示意图。
显示母板包括多个按照相应位置排布的显示面板。在制作如图3所示的丝网31时,丝网中的图案按照显示母板中各个显示面板的相应位置进行排布。每个显示面板之间有一定的距离,便于后续的印刷封装胶与显示面板的切割。
例如,图案311与一个显示面板的大小和位置相对应,图案312与另一个显示面板的大小和位置相对应,图案321也对应一个显示面板。每个显示面板对应的图案的四个拐角位置被设计成具有向内的凹陷,该凹陷的方向朝向显示面板的显示区。尽管未示出,图3中的图案不仅仅包括图案311、图案312和图案313,还包括与其余各个显示面板的大小和位置相对应的图案。丝网中的图案形状和个数与显示母板中的显示面板相对应。
然后,按照制作好的在拐角位置处具有朝向内的凹陷的丝网,采用丝网印刷的方式在封装区形成封装胶。由于制作好的丝网在拐角位置处具有向内的凹陷,则封装胶在封装区的拐角位置的部分处具有朝向显示区的凹陷。丝网具有四个拐角位置,所以封装胶在四个拐角位置处均具有朝向显示区的凹陷。所述封装胶包括玻璃胶,也可被描述为frit胶。
显示母板包括基板和盖板。按照制作好的在拐角位置处具有朝向内的凹陷的丝网,在盖板上的各个封装区采用丝网印刷的方式印刷封装胶。印刷完成后,将盖板与基板进行贴合。然后采用激光照射封装胶。通过激光的能量使封装胶熔融固化,完成对显示母板的封装。丝网印刷是利用有图形的部分网孔透浆料,非图形部分网孔不透浆料的基本原理进行印刷。在进行丝网印刷时,在丝网的一端倒入浆料,用刮刀在丝网的浆料部位施加一定的压力,同时朝丝网的另一端移动。浆料在移动过程中被刮刀从有图形的部分网孔中挤压到盖板上。当刮刀刮过整个印刷区域后被抬起,同时丝网也脱离盖板,一次丝网印刷完成。
图4示出了根据本公开的实施例的封装胶的局部剖视图。
如图4所示,采用丝网印刷的方式在封装区形成封装胶41。封装胶在封装区的拐角位置的部分处具有朝向显示区的凹陷。
在本公开的实施例中,所述封装胶的高度可以为4-10μm,所述封装胶 中在所述拐角位置之外的部分的宽度可以大于300μm。凹陷的形状与尺寸根据实际情况设定,具体的形状不局限于图4中的形状。凹陷的形状可被设计成半圆形、弧形以及半椭圆形等。具体的形状在本公开实施例中不做限制。
在步骤202,在所述封装胶上布置切割线。在所述封装区的所述拐角位置的部分处的切割线延伸到所述凹陷中。
本公开实施例中,在封装好的显示母板上布置切割线。为切割出窄边框的显示面板,切割线在拐角位置之外的部分位于封装胶上。而为了防止封装胶在封装区的拐角位置的部分处发生裂纹,在拐角位置处的切割线延伸到封装胶的凹陷中。
如图4所示,切割线411位于封装胶41上,且在拐角位置处的切割线411延伸到封装胶41的凹陷中。
根据切割线与显示区之间的距离,设定显示面板的具体边框宽度。封装胶41的凹陷处的尺寸大小与显示面板的具体边框宽度相关。
在步骤203,沿所述切割线对所述显示面板进行切割。
本公开实施例中,根据显示母板上排布好的切割线,沿切割线对各个显示面板进行切割,得到分离的多个显示面板。
具体的,采用刀轮沿切割线对各个显示面板进行切割,得到分离的多个显示面板。
在本公开实施例中,一般不采用丝网印刷的方式直接在封装区形成窄边框的封装胶。由于目前丝网印刷的方式具有局限性,当要求的用于窄边框的封装胶的宽度小于等于300μm时,难以控制封装胶的宽度均一性,会造成封装和切割后的显示面板的边框宽度不均,即封装胶的一部分区域宽度大于300μm,而封装胶的另一部分区域宽度小于300μm,使得显示面板的封装效果不佳。显示面板的边框宽度不均会形成较多的凹凸点,进而影响显示面板的信赖性。因此,在窄边框显示面板设计时,通过在所述拐角位置之外的部分印刷宽度大于300μm的封装胶,然后将切割线置于封装胶上,沿切割线对各个显示面板进行切割,得到分离的多个窄边框显示面板。 这样获得的显示面板的封装效果较佳,满足显示面板的信赖性要求。
在本公开的进一步的实施例中,封装胶在所述拐角位置之外的部分的宽度可以为300-700μm。这样既满足显示面板的信赖性要求,又节省了封装胶的消耗。
根据本公开的显示面板的制作方法消除了由于封装胶的在封装区的拐角位置的部分处极易发生裂纹而对封装信赖性测试失败造成的影响,从而提高了显示面板的切割良率。
对于方法实施例,为了简单描述,故将其都表述为一系列的动作组合。但是本领域技术人员应该知悉,本公开实施例并不受所描述的动作顺序的限制,因为依据本公开实施例,某些步骤可以采用其他顺序或者同时进行。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于示例性实施例,所涉及的动作并不一定是本公开实施例所必须的。
本公开的实施例提供了一种显示面板。所述显示面板具有显示区和围绕所述显示区的封装区。所述封装区形成有封装胶。所述封装胶在所述封装区的拐角位置的部分处具有朝向所述显示区的凹陷。
具体的,根据本发明的实施例的显示面板可以是来自显示母板中的一个显示面板。该显示母板包括至少一个显示面板,每个显示面板具有显示区和围绕所述显示区的封装区。
所述封装胶的高度可以为4-10μm,所述封装胶在所述拐角位置之外的部分的宽度可以大于300μm。
在本公开的一个示例性实施例中,封装胶在所述拐角位置之外的部分的宽度可以为300-700μm。
本领域的技术人员应了解,根据本公开的实施例的显示面板可以采用根据本公开的实施例的显示面板的制作方法来制作,也可以采用根据本公开的实施例的显示面板的制作方法之外的制作方法来制作。
根据本公开的显示面板,消除了由于封装胶在封装区的拐角位置的部分处极易发生裂纹而对封装信赖性测试失败造成的影响,从而提高了显示面板的切割良率。
本公开实施例中提供了一种显示装置。所述显示装置包括上述的显示面板。

在此处所提供的说明书中,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,以便不模糊对本说明书的理解。
类似地,应当理解,为了精简本公开并帮助理解各个公开方面中的一个或多个,在上面对本公开的示例性实施例的描述中,本公开的各个特征有时被一起分组到单个实施例、图、或者对其的描述中。然而,并不应将该公开的方法解释成反映如下意图:即所要求保护的本公开要求比在每个权利要求中所明确记载的特征更多的特征。更确切地说,如下面的权利要求书所反映的那样,公开方面在于少于前面公开的单个实施例的所有特征。因此,遵循具体实施方式的权利要求书由此明确地并入该具体实施方式,其中每个权利要求本身都作为本公开的单独实施例。
此外,本领域的技术人员能够理解,尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征,但是不同实施例的特征的组合意味着处于本公开的范围之内并且形成不同的实施例。例如,在下面的权利要求书中,所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
尽管已描述了本申请实施例的示例性实施例,但本领域内的技术人员一旦得知了基本创造性概念,则可对这些实施例做出另外的变更和修改。所以,所附权利要求意欲解释为包括示例性实施例以及落入本申请实施例范围的所有变更和修改。
最后,还需要说明的是,在本文中,诸如第一和第二之类的关系术语 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、商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、商品或者设备所固有的要素。在没有更多限制的情况下,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、商品或者设备中还存在另外的相同要素。
