利用特殊設計的電極及外部分壓電路的配合，經由驅動電壓的調控，可使液晶樣品內部形成電場強度的梯度分佈，並且能簡單地在正或負梯度間變換，使得水平配向的液晶樣品具有正或負型透鏡的特性。由此發展一種可在正負型透鏡特性之間做變換且焦距變化為電場分佈函數之液晶透鏡。此種設計配合現有TFT製造技術即具有開發大尺寸液晶透鏡的潛力。

By using a special design of electrode pattern and the differential biased circuit, the gradient of the electric field distribution inside the liquid crystal sample cell can be achieved through the adjustment of driving voltage. The characteristics of positive or negative types of lens can be converted by changing the polarity of gradient within the sample cell which posses the homogeneous alignment. The liquid crystal lens with a variable focal length and the tunable types of focusing is demonstrated by utilizing the controllable distribution of electric field. This special design incorporating with the fabrication technology of TFT has a potential to develop a large scale of liquid crystal lens.
