利用雷射細微加工系統製做大面積導光模仁

Abstract

隨著液晶顯示器的需求不斷上升，導光板的製程技術影響著面板的表面輝度和成本，在製程技術上將網點直接設計於導光模仁可減少加工的步驟，且利用雷射加工來製作導光模仁有著相當多的優點，但雷射加工在製作大面積導光模仁下有著接縫的問題，且在某些加工條件下會有光暈出現，光暈為多次反射造成的干涉校應，藉由改變雷射加工的架構可避免，接縫是因為加工順序在邊界上的不同，本文會利用演算法的方法來處理。

The demand of LCD is increasing in recently year. The brightness of LCD and cost are predominantly influenced by the light guide plate (LGP). Dot design on the LGP mold can reduce one process. The use of laser processing to make the LGP mold has quite a number of advantages, but laser machining in the production of large area LGP mold have seam problem. The halo appear under certain machining conditions. The halo is the effect of interference caused by multiple reflections. Changing the laser structure can avoid the halo. The seams is the different sequence on boundary. In this article will make use of the algorithm to solve.
