基于动态散射模式的图案化透明显示器OA北大核心

Patterned transparent display based on dynamic scattering mode(DSM)has become a prominent technique in display industry.However,patterned DSM always depend on patterned electrodes,which not only make the preparation process more complex,and increase the cost of the equipment.To solve this problem,our research develops a method for fabricating patterned DSM transparent display which used a mask to expose the liquid crystal(LC)system on fully covered electrodes.By introducing LC monomers into the DSM system and expose on photopolymerization areas,the LC monomers in unexposed area will transfer to exposed area,thus control the distribution of the polymer network.When voltage is applied,the move of ion dopant will be restrained by dense polymer network in exposed area,so the exposed area will be transparent;In unexposed area,the movement of ion dopant changes the orientation direction of LC molecules,which can realize dynamic scattering effect,thus achieve patterned display.The contrast ratio(CR)in exposed area and unexposed area can reach 16.Our research offers a useful technology guidance for functional and industrial development of transparent displays.
