Description
技术领域
本发明属于LCD模组技术领域,尤其涉及一种LCD模组制作方法。
背景技术
目前,LCD模组(显示驱动模组)是电子产品中重要部分,极大影响着电子产品的显示效果;其中,在现有的模组制作方法中,大多数是玻璃面板组件和LCM模组贴合以完成,采用的贴合工艺是全贴合或者框贴合。而现有贴合工艺一般是要在LCM模组中的玻璃面板顶面和底面均粘合偏光片,以实现电子产品的显示成像。在制作过程中,需要将两个偏光片分别粘合在玻璃面板的顶面和底面上的粘合方式,这种双面粘合方式在对于中大尺寸产品的LCD模组(表面积大于600平方厘米)时基于偏光片尺寸也大和双面粘合有偏光片这种易损特性,导致粘合过程是缓慢进行且需要对于精度进行精密控制,这样就会容易在粘合过程中在偏光片和玻璃面板之间吸附大量异物,影响显示效果。
因此,现有技术有待于改善。
发明内容
本发明的主要目的在于提出一种LCD模组制作方法,以解决现有技术中存在的,在制作过程中由于需要精细控制导致制作过程缓慢,使得偏光片和玻璃面板之间容易吸附异物的问题。
为了解决上述技术问题,本发明的一种LCD模组制作方法,包括以下步骤:
步骤S10,在组装显示模组时,将第一偏光片贴合在第一玻璃面板的底部;
步骤S20,在完成所述显示模组组装后,将第二偏光片贴合在第二玻璃面板的上表面或下表面;
步骤S30,将所述第二玻璃面板粘合在第二铁框上表面。
优选地,在所述步骤S10之前,包括步骤:
步骤S1,将反射膜固定在第一铁框内;
步骤S2,将设有灯条的导光板置于所述反射膜上方,将第一铁框和胶框扣合;
步骤S3,将扩散膜、第一增光膜和第二增光膜依次置于所述胶框内,其中,所述第一增光膜位于所述扩增膜和第二增光膜之间。
优选地,所述步骤S30中,所述第二玻璃面板下表面设有双面泡棉胶,所述双面泡棉胶用于粘合所述第二玻璃面板和所述第二铁框。
优选地,在所述步骤S20中,所述第二偏光片基于静电贴粘合在所述第二玻璃面板上表面。
优选地,所述第二偏光片包括PVA层、压敏胶、离型膜、保护膜和两个TAC层,所述两个TAC层分别粘合在所述PVA层的底面和顶面,所述保护膜设置在所述顶面上,所述压敏胶用于粘合所述底面和所述离型层。
本发明具有以下有益效果:
1、第一玻璃面板上不再需要粘合两个偏光片,底面粘合一个偏光片即可,对于第一玻璃面板上不需要粘合偏光片的顶面是可以触碰的,提高对于第一玻璃面板的控制精度且不再具有偏光片受损问题,基于不再需要在第一玻璃面板两侧粘合两个偏光片使得可以显著提高制作速度,避免吸附大量异物。
2、第二偏光片粘合在第二玻璃面板上表面,可以避免第二玻璃面板爆裂时的溅射现象,提高安全性,且制作方法简易。
附图说明
图1为本发明第一实施例的流程示意图;
图2为本发明第二实施例的流程示意图;
图3为本发明第一实施例所制作的LCD模组结构示意图;
图4为本发明第一实施例中第二偏光片的结构示意图。
本发明目的的实现、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
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
参考图1,图1为本发明第一实施例中流程示意图。
如图1所示,本发明的一种LCD模组制作方法,包括以下步骤:
步骤S10,在组装显示模组时,将第一偏光片13贴合在第一玻璃面板14的底部(如图3所示);
本发明的LCD模组制作方法,是针对于中大型电子产品,即所述LCD模组的显示屏或者第二玻璃面板的表面积大于600平方厘米;在步骤S10中,在组装显示模组时,如图3所示,所述显示模组包括第一玻璃面板14、第一偏光片13、导光板7、反射膜6、扩散膜9、胶框8、第一增光膜10、第二增光膜11和第一铁框5;将第一偏光片贴合在玻璃面板的底部是非常重要的步骤,是实现所述LCD模组的显示屏成像的初始条件,对于LCD模组的显示屏成像具有导光作用;所述偏光片也称作偏振光片;其中,第一玻璃面板为ON-CELL玻璃面板,即表示在玻璃面板上配有触摸传感器。
步骤S20,在完成所述显示模组组装后,将第二偏光片15贴合在第二玻璃面板18上表面或下表面(如图3所示);
执行完步骤S10之后,执行步骤S20,在完成所述显示模组组装后,将第二偏光片贴合在第二玻璃面板上表面,步骤S20是与现有技术有较大区别的步骤,现有技术一般而言是将两个偏光片分别贴合于所述第一玻璃面板两侧,而步骤S20,是将其中一个贴合在所述第一玻璃面板两侧的第二偏光片贴合在第二玻璃面板上表面或下表面,首先基于偏光板是较软且粘合性强,如果发生第二玻璃面板爆裂,因为第二玻璃面板是基于用户操作实现控制功能,基于偏光板贴合在所述第二玻璃面板上表面,可以避免第二玻璃面板的碎片爆裂现象,提高保护性;然后,第一玻璃面板上不再需要粘合两个偏光片,底面粘合一个偏光片即可,对于第一玻璃面板上不需要粘合偏光片的顶面是可以触碰的,不像以前需要顾虑到偏光片的表面完整性而不敢使用机械手进行微操,改进后,基于步骤S20,所述顶面就可以利用机械手微操或者固定,以提高控制扣合过程中的精度。其中,如图4所示,所述第二偏光片包括PVA层23、压敏胶25、离型膜26、保护膜22和两个TAC层24,所述两个TAC层24分别粘合在所述PVA层23的底面和顶面,所述保护膜22设置在所述顶面上,所述压敏胶25用于粘合所述底面和所述离型层;本实施例对于第二偏光片的结构进行限定,以使得在所述第二玻璃面板爆裂时所产生的碎片基于上述结构所组成的软质特性和粘合性强的符合结构不会飞溅,提高发生意外时对于使用者的保护性,同时基于ON-CELL玻璃面板和第二玻璃面板所构成的显示组件对于LCD模组的成像至关重要,主要是基于在两个偏光片之间夹着玻璃面板才能实现成像的原理。
步骤S30,将所述第二玻璃面板18粘合在第二铁框16上表面(如图3所示)。
在执行完步骤S20后,将所述第二玻璃面板18粘合在所述第二铁框16上表面,即完成LCD模组的整体固定;具体地,在所述第二玻璃面板18下表面放置双面泡棉胶17,所述双面泡棉胶17用于粘合所述第二玻璃面板18和所述第二铁框16;提高了第二玻璃面板和第二铁框的牢固性,且通过双面泡棉胶缓冲所述第二玻璃面板受到外力时的冲击力大小。
参考图2,图2为本发明第二实施例的流程示意图。
如图2和图3所示,优选地,在所述步骤S10之前,包括步骤:
步骤S1,将反射膜6固定在第一铁框5内;
步骤S2,将设有灯条4的导光板7置于所述反射膜6上方,将第一铁框5和胶框8扣合;
步骤S3,将扩散膜9、第一增光膜10和第二增光膜11依次置于所述胶框内,其中,所述第一增光膜位于所述扩增膜和第二增光膜之间。
在步骤S10之前,是对于导光板、反射膜、扩散膜、第一增光膜、第二增光膜和第一铁框之间的组装进行限定,即组装显示模组的过程;首先执行步骤S1,将反射膜固定在第一铁框内;然后,执行步骤S2,将设有灯条的导光板置于所述反射膜上方,将第一铁框和胶框扣合,所述导光板7和扩散膜9之间通过第三固定胶2粘合,所述第三固定胶为3M胶,在步骤S2中,将所述灯条4基于双面胶3粘合在所述导光板7上,然后执行步骤S3,将扩散膜、第一增光膜和第二增光膜依次置于所述胶框内,并且将第一固定胶1和第二固定胶12粘合在所述第二增光膜上,所述第一固定胶和第二固定胶均为3M胶,但不局限于上述;其中,导光板是现有的亚克力板材;所述反射膜是现有的金属反射膜;而对于扩散膜是具有若干孔状的金属膜片;第一增光膜是透明的PET薄膜;基于上述S1、S2和S3步骤以完成显示模组的部分组装;避免在后续进行第一偏光片贴合时基于需要考虑导光板和第一增光膜的组装位置而影响到第一偏光片的贴合效果。
优选地,在所述步骤S20中,所述第二偏光片基于静电贴粘合在所述第二玻璃面板上表面;本优选实施例中,所述静电贴为PVC静电膜,使得所述第二偏光片是基于静电贴附在所述第二玻璃面板上表面,以在制作LCD模组过程中减少异物吸附,即减少LCD模组坏点现象。
以上仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
