Description

微结构、显示装置及其显示面板 技术领域
本发明涉及显示器技术领域，尤其涉及一种微结构、显示装置及其显示面板。
背景技术
显示装置通常在表面设置有一层盖板玻璃，由于显示装置盖板玻璃的反射作用，显示装置在较强的外部环境光下工作时，环境光照射到显示装置表面会发生反射。当反射率较高时，将严重影响显示画面的观看效果，甚至根本看不清显示画面。
为了解决这一问题，需要对盖板玻璃表面进行防反射处理；在盖板上蒸镀各种防反射薄膜是当前最常用的方法。虽然防反射薄膜可降低盖板玻璃表面的反射率，但是，该方法也存在较大局限性；一般情况下，在玻璃表面蒸镀单层防反射薄膜只能降低单一波长的反射，目视盖板玻璃会出现比较明显的色偏现象；此外，尽管在盖板玻璃表面蒸镀多层防反射薄膜可以降低盖板玻璃在可见光波长范围内(380nm～780nm)的反射率，但是复杂的膜层结构会大大增加加工成本且其性能稳定性也会有所下降。
目前，受飞蛾眼睛的启发，人们提出了一种在盖板玻璃表面制备周期性微纳结构的方法，通过这些微纳结构可在可见光范围内降低盖板玻璃的反射率。蛾眼表面具有一层六角蜂窝状纳米结构，该结构的特征尺寸在百纳米量级，小于入射光波长。在该尺度范围内，光波入射到微纳结构表面时无法辨认出该微结构，使得材料表面的折射率沿深度方向呈连续变化，能够减小折射率急剧变化所造成的反射现象，从而有效降低材料的反射率。‘蛾眼’结构的三维形貌以及空间分布对盖板玻璃的反射率有很大影响，因此，需要提供一种能够使得盖板玻璃具有较低反射率的‘蛾眼’结构设计。
