Description

一种光学薄膜及电子设备盖板 技术领域
本发明涉及薄膜技术领域,尤其涉及一种光学薄膜电子设备盖板。
背景技术
现有的很多技术领域要求产品的颜色或者图文呈渐变的效果,这样给人们一个视觉上的过度,在某些程度上也能起到安全的效果;例如,现有产品市场上电器的外壳、手机的外壳、或者一些电子设备上的贴膜、或者交通工具上的贴膜也需要渐变的效果。
现有技术中的颜色渐变采用的技术方案有多种选择,例如,采用印刷技术印刷不同的油墨,通过调色是的颜色或者图案产生渐变;或者通过采用提拉的方式得到颜色的渐变的效果,再或者使用磁粉材料实现颜色的渐变效果。但是这些技术方案都会带来一些技术问题,采用第一种技术方案通过调色来实现的,这样使的产品的分辨率不够高,出现点纹;第二种技术方案所形成的产品在图文之间会出现不稳定以及重复性差;第三种采用磁粉实现渐变的效果成本太高,作为工业生产价格比较高。
鉴于此,本发明通过改变图文结构以解决所存在的技术问题。
