本論文主題為研發一光寫入穿透式液晶顯示器，此顯示器不需要外在的電壓驅動。它的顯示機制是藉由摻雜一種雷射引致吸附配向的偶氮染料，並且可以藉由改變寫入雷射光場的偏振方向以及加熱此摻雜偶氮染料的液晶盒來顯示想要的資訊。在妥善的控制溫度及寫入光場的強度下，我們可以保留不想改變的資訊，並且洗去不要的資訊，然後寫入新的資訊。此光寫入穿透式液晶顯示器的製作過程容易，並且可以再覆寫的次數內(~20次)維持對比度>5。

This work presents a photo-addressable memory transmissive liquid crystal display (PTLCD) that can be operated without power supply, and conductive layer. The mechanism is based on the photo-induced adsorption alignment layer of azo dyes, which then align LCs. The adsorbed dye alignment layer can be re-oriented by changing the direction of the writing laser beam and heating the sample simaltaneously. This transmissive liquid crystal display is extremely simple to fabricate, and can be optically written, erased and re-written for ~20 times with a contrast larger than 5.
