液晶高分子製作及開發LCD 3D Lens

Abstract

本研究描述利用液晶高分子做為製作3D凸透鏡陣列之材料，同時運用液晶具有雙折射率的性質，達成2D與3D模式可切換之裸視3D顯示技術，並擁有高亮度及多視角設計，以完成新穎立體顯示器之開發。 以樹酯材料凹透鏡及玻璃作為基材，玻璃先經由聚亞醯胺(PI)薄膜塗佈，以布毛摩擦(rubbing)方式分別使樹酯及PI表面具有溝槽，再利用狹縫塗佈方式將液晶高分子塗佈於聚亞醯胺薄膜之上，並於真空環境下將凹透鏡與玻璃兩者對組，後續施以外加應力及退火(annealing)程序使液晶分子規則性排列，完成後照射紫外光使其進行聚合反應，最後移除玻璃基材。 實驗結果顯示，利用上述製作方式，透過控制布毛摩擦條件、外加應力方式和退火溫度曲線，可以有效使液晶分子規則性排列，以完成液晶高分子凸透鏡陣列薄膜之製作。

This study describes use liquid crystal polymer (LCP) as the material of 3D convex lens array. The use of the nature of liquid crystal birefringence, we reach to 2D and 3D mode switchable naked-eye 3D display technology. It also has high brightness and multi-view angle advantages. We use the above features to complete the development of novel 3D display. We use resin material as a substrate of concave lens. Besides, we are coating polyimide (PI) film on the glass substrate. We let those two substrates with grooves on surface by cotton cloth rubbing method, respectively. After LCP are coated on top of the PI glass substrate. We assemble those two substrates in a vacuum environment. Then we apply stress and annealing procedures to align liquid crystal molecules. The liquid crystal material is polymerized by UV light exposure. Finally, we remove the glass substrate. The experiment results show that use of the above-mentioned production methods, through the control of rubbing conditions, stress applied method and temperature curve of anneal. We can make effectively alignment of liquid crystal molecules. Then we complete the LCP lens array fabrication of 3D display.
