附图说明

图2是本申请实施例提供的显示面板的制造方法的流程示意图。
本发明的实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清 楚、完整地描述。显然,所描述的实施例仅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,本领域技术人员在没有作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。
本申请实施例提供了一种显示面板及其制造方法,以下将分别进行详细说明。
请参阅图1,图1是本申请实施例提供的一种显示面板的结构示意图。该显示面板10可以包括相对设置的第一柔性基板101和第二柔性基板102、以及涂布于第一柔性基板101或第二柔性基板102上的框胶103。需要说明的是,第一柔性基板101可以是阵列基板,第二柔性基板102可以是彩膜基板。或第一柔性基板101为彩膜基板,第二柔性基板102为阵列基板。
该框胶103包括框胶主体和具有端环氧基封端的芳香族聚酯类聚合物。在本申请实施例中,该具有端环氧基封端的芳香族聚酯类聚合物和该框胶主体的质量百分比为5%-30%。
其中,框胶主体可以按照质量百分比,由15%-30%的亚克力树脂、40%-60%的环氧树脂、1%-3%的光引发剂、5%-15%的硬化剂、1%-2%的添加剂以及5%-15%的填充物组成。
其中,具有端环氧基封端的芳香族聚酯类聚合物可以由超支化聚酯和环氧氯丙烷反应生成。该超支化聚酯可以为2代超支化聚酯(HBP2)、3代超支化聚酯(HBP3)或4代超支化聚酯(HBP4)中的一种或多种。
例如HBP2与环氧氯丙烷反应生成具有端环氧基封端的芳香族聚酯类聚合物的化学方程式为:
Figure PCTCN2019128129-appb-000001
其中,R-(OH) 12的结构式为:
Figure PCTCN2019128129-appb-000002
具体的,可以将超支化聚酯和环氧氯丙烷以2:1的物质的量加入一反应器皿中,并加入一定量的乙酸作为溶剂,加热至70℃-100℃,回流8-17小时后,使用旋转蒸发仪蒸发掉多余溶剂,并用热水洗涤除掉多余的环氯丙烷,最后进行烘干得到粘稠体物质,该粘稠体物质即为具有端环氧基封端的芳香族聚酯类聚合物。
在本申请实施例中,框胶103可以通过在框胶主体中添加该具有端环氧基封端的芳香族聚酯类聚合物制得。该过程可以在调框胶时同时进行,无需增加额外的工艺。
具体的,可以称取一定量的框胶主体放入调胶瓶,再称取一定量的具有端环氧基封端的芳香族聚酯类聚合物放入调胶瓶,然后在常温下搅拌30分钟,以脱去气泡,使得框胶主体和具有端环氧基封端的芳香族聚酯类聚合物充分混合,得到均一的混合物。在本申请实施例中,具有端环氧基封端的芳香族聚酯类聚合物和该框胶主体的质量百分比为5%-30%。需要说明的是,为了较大程度的提升框胶的韧性,且对转变温度等性能改变较小,具有端环氧基封端的芳香族聚酯类聚合物和该框胶主体的质量百分比可以为8%-18%。
请参阅图2,图2是本申请实施例提供的显示面板的制造方法的流程示意图。该显示面板10的具体制造流程可以如下:
201、提供第一柔性基板101和第二柔性基板102。
202、提供一框胶103,所述框胶103包括具有端环氧基封端的芳香族聚酯类聚合物。
203、将所述第一柔性基板101和所述第二柔性基板102相对设置,并在所述第一柔性基板101或所述第二柔性基板102上涂布所述框胶103。
204、对所述框胶103进行紫外线照射。
205、对所述框胶103进行热固化。
在本申请实施例中,第一柔性基板101和第二柔性基板102成盒形成显示面板10后,框胶103还处于未固化状态。因此需要对框胶103进行固化处理。具体的,可以对该框胶103的外层框胶进行紫外线预固化,并同时对该框胶103的外层框胶和内层框胶进行热固化。其中,热固化的温度可以为80-150℃,加热时间可以为30-120min。
在对该框胶103进行热固化的过程中,框胶103中的环氧树脂进行交联聚合固化。同时,具有端环氧基封端的芳香族聚酯类聚合物表面具有大量的反应端基,可以和环氧树脂的化学键相连接。
当该显示面板10弯折时,框胶103中的具有端环氧基封端的芳香族聚酯类聚合物粒子受到外界应力作用,从而产生空穴,空穴引起应力集中,可吸收掉大部分应力。
同时,环氧树脂的化学键和具有端环氧基封端的芳香族聚酯类聚合物表面的反应端基相连接可以产生扭曲空间,该扭曲空间也可以分担一部分应力,使得框胶103不易断裂或剥离。具体的,由于具有端环氧基封端的芳香族聚酯类聚合物的端基和环氧树脂的化学键相连接破坏了网络的规整性,因此在具有端环氧基封端的芳香族聚酯类聚合物粒子周围发生扭曲,形成扭曲空间。当应力经过该扭曲空间时,扭曲空间存在大量的相互作用力,诱发局部剪切力屈服,可以进一步减少应力集中。
本申请实施例提供的具有端环氧基封端的芳香族聚酯类聚合物的框胶103固化后韧性较高,将该框胶103涂布于第一柔性基板101或第二柔性基板102可以极大降低显示面板10弯折时,框胶103出现断裂或剥落的问题,提高显示面板10的可靠性。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种显示面板及其制造方法进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想;本领域的普通技 术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
