本发明涉及显示领域,尤其涉及一种异形显示屏封胶方法。
背景技术
近年来随着全面屏手机的兴起,带缺口(Notch)或面内开孔(hole)的异形显示屏逐渐成为大众关注的焦点。由于异形屏设置有带缺口的边或是开孔处,不仅容易漏光,造成亮线缺陷,而且这些缺口、开孔处一般用于放置摄像头或是传感器,其表面硬度相对较高,在与屏幕(pannel)玻璃进行装配时,容易相互刮伤。因此,在这些带缺口的边或是开孔处需要采用本发明提供的封胶方法进行处理。
目前市场上已有一些异形屏的封胶设备,但从目前的试验效果来看,主要存在胶厚不均匀的问题,详见下图2所示(本申请结合现有技术提供的一种异形显示屏的第一结构图),缺口1的外圆角处11胶厚偏小,内圆角处12胶厚偏大,胶厚波动范围达到±50%;开孔处2(R=5.5mm)靠近缺口1一端13胶厚偏小,远离缺口1一端14胶厚偏大,胶厚波动范围达±20%,而当开孔半径R变小时,此波动范围还会更大。胶厚的不均匀情况,将直接影响到摄像头、传感器等器件的装配误差。

本发明提供的一种异形显示屏封胶方法的实施方式,具体请参阅下图1、图3以及图4进行说明,图1为本申请实施例提供的一种异形显示屏封胶方法的第一流程示意图,主要介绍了本申请异形显示屏封胶方法的几个步骤;图3为本申请实施例提供的一种异形显示屏的第二结构示意图,主要包括:缺口部1,开孔部2,异形显示屏的第一侧边101,异形显示屏的第二侧边103,异形显示屏的第三侧边102,异形显示屏的第四侧边104,异形显示屏100以及机身105;图4为本申请实施例提供的一种异形显示屏的第二流程示意图,其中4A为一预设有点胶区域的异形显示屏;4B为设置了定位标记的异形显示屏机身,401为第一点胶区域,402为第二点胶区域,403为异形显示屏外侧的机身非显示区,即定位标记处,404为异形显示屏显示区;4C为点胶完成后的异形显示屏;4    D为封胶完成之后的异形显示屏。
图1的第一流程结构图简述了异形显示屏封胶方法的几个步骤,主要包括:
首先,提供一异形显示屏100,所述异形显示屏表面设置有预设点胶区域,所述预设点胶区域包括第一点胶区域401和第二点胶区域402,所述第二点胶区域402的预设点胶厚度,大于所述第一点胶区域401的预设点胶厚度;在异形显示屏外侧的机身非显示区403设置定位标记;使用点胶设备在所述第一点胶区域401和所述第二点胶区域402进行点胶;使用激光切割设备的电荷耦合元件摄像头匹配所述定位标记,并对所述第二点胶区域402的胶层进行减薄处理,使得所述第二点胶区域402的胶厚与所述第一点胶区域401的胶厚相同。
其中,所述异形显示屏100的第一点胶区域401包括:第一侧边101、第二侧边103、第三侧边102及第四侧边104;所述异形显示屏的第二点胶区域402包括:缺口部1或是开孔部2。
根据本发明提供的一优选实施例,所述步骤“S20”包括:分别在对所述异形显示屏100的缺口部1或是开孔部2外侧的机身非显示区403设置定位标记。再分别对所述异形显示屏的第一侧边,第二侧边,第三侧边以及第四侧边外侧的机身非显示区403设置定位标记。详见图4中4B。
根据本发明提供的一优选实施例,所述第一侧边101和所述第二侧边103平行且相对;所述第三侧边102和所述第四侧边104平行且相对。
根据本发明提供的一优选实施例,所述步骤“S30”包括:分别对所述异形显示屏100的第一侧边101,第二侧边103;第三侧边102;第四侧边104以及缺口部1或是开孔部2进行点胶,然后对点胶处进行固化,最后,再对点胶完成的效果进行检查,详见图4中4C。
根据本发明提供的一优选实施例,胶材颜色为黑色。本发明的模组封胶方法区别于显示屏与手机机壳组装的点胶方法,整机组装时点胶的主要作用是密封和固定,其使用的胶材颜色根据机壳外观有黑色、白色等多种颜色。而本发明提供的异形显示屏封胶方法中,胶材颜色为黑色:一是进行结构固定(用于粘合显示模组的玻璃和背光两部件);二是防漏光;三是提高模组的抗静电性能和结构缓冲作用(防镜头刮擦等)。
根据本发明提供的一优选实施例,点胶种类为热熔胶或是紫外固化胶。
热熔胶(Hot Glue)是一种可塑性的粘合剂,在一定温度范围内其物理状态随温度改变而改变,而化学特性不变,其无毒无味,属环保型化学产品;无气味,折迭柔软,具有一定的弹性,可以作为镜头等的缓冲材料。用后也不会因温度低出现脱胶现象;生产工艺也十分简单,时现阶段使用最多的胶种之一。
紫外固化胶,又称UV胶(Ultraviolet Rays)是一种必须通过紫外线光照射才能固化的一类胶粘剂,它可以作为粘接剂使用,也可作为油漆、涂料、油墨等的胶料使用。其固化原理是UV固化材料中的光引发剂(或光敏剂)在紫外线的照射下吸收紫外光后产生活性自由基或阳离子,引发单体聚合、交联化学反应,使粘合剂在数秒钟内由液态转化为固态。因此,其固化速度更快。这两种胶都非常适合用于电子设备屏幕的粘合。
根据本发明提供的一优选实施例,采用喷涂方式进行点胶。目前点胶方式基本是采用一个喷阀喷涂,常规显示屏(无缺口部或开孔部)的喷涂方式是载台不动,喷阀移动;但异形显示屏在喷涂时,喷阀和载台均会移动。
根据本发明提供的一优选实施例,所述步骤“S40”包括:首先,用激光切割设备的电荷耦合元件摄像头匹配所有标有定位标记的位置;然后,用激光切割设备切割所述异形显示屏100的缺口部1和开孔部2;最后再检查切割完成的第二点胶区域402的厚度是否与所述第一点胶区域401厚度一致,详见图4中4D。
根据本发明提供的一优选实施例,所述胶厚精度在±0.03mm范围内。
结合图3可以看出,缺口部1或是开孔部2设置在异形显示屏100上,靠近异形显示屏的第一侧边101处,异形显示屏的第一侧边101与异形显示屏的第二侧边103平行且相对,异形显示屏的第二侧边102与异形显示屏的第三侧边104平行且相对,整个异形显示屏100覆盖在机身105上。该异形显示屏可以是LCD(Liquid Crystal Display,LCD)显示屏或是OLED(Organic Light-Emitting Diode, OLED)显示屏,可以是手机、平板或是任何其他包含异形显示屏的设备。
以上对本发明实施例所提供的一种异形显示屏封胶方法进行了详细介绍,本文中应用了具体个例对本发明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发明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发明各实施例的技术方案的范围。
