Description

一种防蓝光的手机屏幕盖板及其制造方法 技术领域
本发明涉及一种防蓝光的手机屏幕盖板及其制造方法。
背景技术
随着现代生活手机的普遍使用，而且人们的生活越来越离不开手机，有很多人经常性的使用手机带来的结果是眼睛出现酸涩、疼痛、流泪等不舒服症状，更严重的出现视力下降，这些不舒服的症状是因为眼睛长时间对手机屏幕，由手机屏幕所散发出来的有害光线所致，手机屏幕发出的光是眼睛的大敌，普遍手机屏幕供应商为了体现手机屏幕的色彩对比度及饱和度，会提高手机屏幕背后的灯光亮度，这样会使屏幕表面像装了一片玻璃一样显得有质感，提高了清晰度，同样它也会像玻璃一样反射光线，但光线照向屏幕时会增加光线反射，尤其是晚上的时候消费者在使用手机时，LED灯光照向手机屏幕会增加光线反射，这样很容易被这些光线伤害到眼睛，并产生视觉疲劳的症状，慢慢的会引起视力下降和头痛的健康问题，，手机屏幕产生的“不舒服的光”持续照射我们的眼睛还会引起视觉系统失调，手机屏幕发出的光让我们眼睛不舒服是因为这些光线里面含有大量不规则频率的高能短波蓝光，这些短波蓝光具有能量能穿透我们的眼球晶体直达视网膜，短波蓝光持续照射视网膜会产生大量自由基离子，这些自由基离子会使得视网膜的色素上皮细胞衰亡，上皮细胞的衰会使感光细胞缺少养分而引起视力损伤；这些短波蓝光也是引起黄斑部病变的主要起因，我们每天长时间面对手机屏幕产生的蓝光刺激，殊不知蓝光波长短能量高，易引起眼睛视觉上的干涩、畏光、疲劳等早发性白内障、自发性黄斑部病变。蓝光约占可见光的50～60％，而蓝光也是引起黄斑部病变的主要原因之一，严重可能导致失明。蓝光会刺激视网膜产生大量自由基离子，使得视网膜色素上皮的萎缩，再引起光敏感细胞的衰亡，这是因为我们所处的是信息时代，人们的工作与学习都离不开手机,面对手机屏幕的时间越来越长,用眼的频率也越来越高。眼睛开始酸涩、疼痛、流泪，它凄切的告诉我们：我们的眼睛已经受到了伤害，需要在使用手机时得到保护。目前手机屏幕发出的蓝光、电磁波、自由电子它们均会对眼睛造成伤害，为了保护眼睛，必须加以过滤，而目前过滤手机屏幕蓝光的方法是在手机屏幕表面贴一层保护膜，手机屏幕贴膜以后，透光率往往会下降，所贴的膜容易产生划痕影响视觉效果，对防蓝光效果依然不够理想。手机屏幕盖板的材质大部分是有机玻璃(聚甲基丙烯酸酯)，这种有机玻璃容易破碎，抗冲击性能不理想。
发明内容

A2、镀防蓝光膜层：采用电子枪将防蓝光膜层的膜材进行蒸发后，在离子源的作用下所述膜材以纳米级分子形式沉积于步骤A1中抗冲击强化膜层的表面，形成防蓝光膜层，防蓝光膜层的厚度为0.1-600纳米；所述防蓝光膜层的膜材包括以下重量百分比的组分的混合物：氧化锡30％-60％；铷10％-40％；铂10％-40％；
A3、镀导电膜层：采用电子枪将导电膜层的膜材进行蒸发后，在离子源的作用下所述膜材以纳米级分子形式沉积于步骤A2中防蓝光膜层的表面，形成导电膜层，导电膜层的厚度为0.1-600纳米；所述导电膜层的膜材为氧化铟锡；
A4、镀防油污膜层：采用电子枪将防油污膜层的膜材进行蒸发后，在离子源的作用下所述膜材以纳米级分子形式沉积于步骤A3中导电膜层的表面，形成防油污膜层，防油污膜层的 厚度为0.1-600纳米；所述防油污膜层的膜材包括以下重量百分比的组分的混合物：氟化镁60％-80％；氧化铟锡20％-40％；
防油污膜层镀膜完成，基板的外表面镀膜系完成后，转入基板的内表面镀膜系；
B、基板的内表面镀膜；
B1、镀抗冲击强化膜层：采用电子枪，将抗冲击强化膜层的膜材进行蒸发后，在离子源的作用下所述膜材以纳米级分子形式沉积于基板内表面，形成抗冲击强化膜层，抗冲击强化膜层的厚度为0.1-600纳米；所述抗冲击强化膜层的膜材包括以下重量百分比的组分的混合物：氧化硅20％-80％；氧化锆20％-80％；
B2、镀导电膜层：采用电子枪将导电膜层的膜材进行蒸发后，在离子源的作用下所述膜材以纳米级分子形式沉积于步骤B1中抗冲击强化膜层的表面，形成导电膜层，导电膜层的厚度为0.1-600纳米；所述导电膜层的膜材包括以下重量百分比的组分：所述导电膜层的膜材为氧化铟锡。

b、采用水基清洗剂对经步骤a清洗的基板进行清洗，并以超声波辅助清洗；
c、将步骤b处理的基板依序进行自来水漂洗和蒸馏水漂洗。
基板外表面和内表面的抗冲击强化膜层的作用：1、能使基板的耐冲击性能提高，基板不容易破碎避免伤害眼睛；2、提高基板的附着力，可以作为镀下一层膜层的介质有着很好粘结作用使得膜层间不容易脱层。
基板外表面的防蓝光膜层的作用：防蓝光膜层是一种白色透明的膜层(白金膜层)能更独特有效的过滤有害蓝光和紫外线以及各种对人体有害的射线；针对波长为380-500nm的蓝光吸收率达到达33％以上，使得视觉轻松，进而缓解视觉疲劳从而能进入理想的视觉状态。
基板外表面的防油污膜层的作用：手机屏幕盖板表面镀有多层膜后，盖板膜层表面特别容易产生污渍，而污渍会破坏膜层效果。在显微镜下，我们可以发现膜层呈孔状结构，所以油污特别容易浸润至膜层。解决的方法是在膜层上再镀一层具有抗油污和防水性能的膜层，该膜层不但不会改变其他膜层的光学性能，且还具有抗油污、耐磨擦以及导电效果；防油污膜层将已镀上盖板表面的膜层覆盖起来，并且能够将水和油与手机屏幕盖板的接触面积减少，使油和水滴不易粘附于手机屏幕盖板表面。
本发明采用电子束真空蒸镀的原理，利用带电荷的粒子在电场中加速后具有一定动能 的特点，将离子引向欲被镀膜的基板制成的电极，并通过电子枪高温轰击将高纯度金属氧化物组分，蒸发出来的纳米分子使其沿着一定的方向运动到基板并最终在基板上沉积成膜的方法。本项发明技术结合利用磁场的特殊分布控制电场中的电子运动轨迹，以此改进镀膜的工艺，使得镀膜厚度及均匀性可控，且制备的膜层致密性好、粘结力强及纯净度高。
