为什么有些智慧黑板不怕屏幕进粉尘？

2020-12-19 10:34

屏幕进灰，是每个带“屏”的电子产品在使用过程中的一大困扰，繁星点点般的灰尘，简直要逼死强迫症。但为什么近几年来却很少有人再提起手机屏幕进灰的问题？探讨触摸屏的贴合方案发现，这与全贴合工艺在手机的普及直接相关。

 

所谓全贴合，即以均匀填充的方式，用光学级水胶将玻璃盖板与显示面板贴合，构造出无空气夹层的高规格显示器件。相较于触摸屏早期采用的传统框贴工艺，这一工艺消除了空气层，隔绝了灰尘进入的途径，有效减少了屏幕进灰的现象。除此之外，因为减少了面板与玻璃之间的反光，触控显示无任何视觉偏差，在阳光照射下仍清晰可见。

 

全贴合比之框贴的提升并不是一两点的事情，从缝隙灰尘、显示效果、再到触控体验来说，都是全贴合显示屏更占优势，而在当下大尺寸触摸屏市场中，框贴工艺由于成本优势中占据较大的市场份额，导致很多用户其实还在“重温”当年刚接触触摸屏时、隔着厚厚一层玻璃触摸的体验，殊不知如今的大尺寸触摸屏已经能做到零距离的触控体验，书写流畅低延迟。

因模组尺寸大、边框窄，大尺寸触摸屏的框贴的双面胶使用量还受限制，产品可靠性差；当tw和lcd受到挤压时，双面胶将无法恢复支撑，导致产生贴合牛顿环，造成显示不良；框贴工艺周边的边框还容易积灰、进灰，直接影响其显示画质及使用寿命。

基于以上框贴工艺的种种劣势，全贴合工艺在高粉尘的使用环境、高使用频率的智慧教育领域上率先得到大规模应用，成功让部分智慧黑板不怕“吃灰”，使用寿命更长。据discien数据显示，2020年一季度中国智慧黑板市场全贴合占比达到67%，随着全贴合良率和效率的提升，全贴合的普及率持续提高，并将完全取代框贴技术。

我司是一家专业生产大尺寸电容触摸屏及显触一体化产品的供应商，强大的研发团队、精良的生产工艺、丰富的制造经验，使我司较早在大尺寸触摸屏上推行全贴合技术。

我司江苏生产制造基地的百级无尘车间工厂里，布局着全尺寸tpm全贴合生产线，2018年来，这条生产工艺先进、生产良率高的全贴合生产线实现运行，在业内颇具盛名。

 

我司全贴合工艺亮点在于减少了贴合过程中增加的空气层，不仅防尘、抗冲击，屏幕可视角度还高达178°，触控时精度在1.5mm内、响应时间不少于0.01s，屏幕息屏后不发白，实现一体化。华科创智全贴合工艺已广泛应用于金融、教育、医疗等垂直行业的商显终端产品，大幅改善相应产品的外观、性能及体验等。

正如手机贴合工艺的发展一样，全贴合未来也将成为大尺寸触摸屏的标配工艺，届时，屏幕进灰的困扰在大尺寸领域也将不复存在。华科创智成熟、全尺寸的全贴合生产线，加之全产业链的成本优势、稳定的规模量产能力，会是这一业务代工的绝佳之选！
