Description

屏幕贴膜
本申请要求于2017年06月08日提交中国专利局的申请号为201710427833X、名称为“一种屏幕贴膜”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电子产品配件领域，尤其涉及一种屏幕贴膜。
背景技术
随着电子产品的飞速发展，由于美观及实用性的需要，采用曲面屏的电子设备越来越多。曲面屏在日常使用的过程中，容易出现磨损，这对曲面屏的美观及寿命会造成极大的影响。为对曲面屏进行保护，需要在曲面屏上粘贴屏幕贴膜。
目前市面上流通的屏幕贴膜，由于种种原因，在与曲面屏进行贴合过程中，因为张力、弧度等因素，使得边缘飘起，从而导致密封性不良，接触不良，边缘灰尘密布。
具体的，主要是因为屏幕贴膜的中间部分采用网点印刷工艺，在装配到曲面屏上时，中间部分会处于悬空的状态，与曲面屏贴合不紧密且存在缝隙。这还会造成触摸不良，在进行手势操控时，需要大力按压使屏幕贴膜变形才能触摸到曲面屏。
由于曲面屏与屏幕贴膜的中间部分有缝隙，大力按压中间部分的时候，造成屏幕贴膜边缘飘起，继而进一步地影响到曲面屏与屏幕贴膜之间的密封性。在水汽严重的环境下，曲面屏与屏幕贴膜之间还容易出现湿点，影响曲面屏的使用，出现触摸不良的现象。
