| dc.description.abstract | 本論文先以液晶模擬軟體2dimMOS模擬分別探討傳統圓孔型電極液晶透鏡，具有額外電極之圓孔型電極液晶透鏡，曲面型電極液晶透鏡之電位分佈。由電位分佈判斷三種透鏡尺寸為毫米之透鏡是否在液晶層能形成連續分佈，並且產生不均勻之電場，進而使得液晶層內產生折射率分佈，進而形成液晶透鏡。本論文更進一步探討圓孔型電極液晶透鏡與曲面型電極液晶透鏡在高填充因子之目標下，兩種透鏡間電位分佈是否會有平緩之情形發生，透鏡間產生有crosstalk之現象。最後，本論文也包含四種透鏡尺寸之曲面型電極液晶透鏡製程，而透鏡尺寸是從微米到毫米。我們將精密加工所之透鏡做為母模，然後運用二次翻模之技術並利用旋轉塗佈，將導電高分子PEDOT:PSS均勻旋塗於透鏡以製造曲面電極，再使用NOA65填平並旋塗上PVA作為配向膜，並將其與ITO玻璃封裝成液晶盒，最後注入液晶形成液晶透鏡。 | zh_TW |
| dc.description.abstract | In this thesis, we use liquid crystal simulation software 2dimMOS to investigate the electric potential of liquid crystal lenses with hole-pattern electrode, hole-pattern with additional electrode and spherical electrode. We analyze the electric potential to determine whether the three kinds of liquid crystal lenses with the lens sizes of millimeters can form a continuous electric potential distribution in the liquid crystal layer and the non-uniform electric field could be generated. The refractive index distribution generated by non-uniform electric field in the liquid crystal layer forms a liquid crystal lens. We further investigate whether the hole-pattern electrode with additional electrode liquid crystal lens and the spherical electrode liquid crystal lens have flat potential distribution between the two adjacent lenses and crosstalk occurs consequently. Fabrication of four sizes of liquid crystal lenses range from micrometers to millimeters is also included. Replication process is used and conductive polymer PEDOT:PSS is applied to form spherical electrode. We assemble flattened spherical electrode with ITO glass with PVA to form liquid crystal lens. | en |
