This Small Business Technology Transfer (STTR) Phase I project is to synthesize and characterize new optically addressed molecular switches and incorporate them into an innovative reflective display films. These materials will then be studied for optical addressing and erasing of high-resolution images under various molecular alignments achievable in an electro-optic driven bi-stable display cell. Prototype display films coated on thin flexible plastic substrates well be fabricated and evaluated for control of image lifetime in ambient light and for use as a low-cost (pennies) display for tagging and related applications.Photochemical chiral materials will be utilized to create a photographic film in which an image can be erased and a new image optically addressed repeatedly on the same film. As a paper replacement, these displays are developed for such applications as point of purchase, identification, and production line tags as well as updatable displays on credit and debit cards. If successful, this will create a new market that electronically addressed displays have not been able to penetrate because of their high cost due to attached drive and control electronics.

这个小型企业技术转移(STTR)第一阶段的项目是合成和表征新的光寻址分子开关，并将它们整合到创新的反射显示薄膜中。然后将研究这些材料，用于在电光驱动的双稳态显示单元中实现的各种分子排列下的高分辨率图像的光学寻址和擦除。涂覆在薄的柔性塑料衬底上的原型显示薄膜可以很好地制造和评估，以控制环境光中的图像寿命，并用作标签和相关应用的低成本(便士)显示器。光化学手性材料将被用于制造一种照相薄膜，其中可以在同一薄膜上重复擦除图像和光学寻址新图像。作为纸的替代品，这些显示器被开发用于诸如购买点、识别和生产线标签以及信用卡和借记卡上的可更新显示器等应用。如果成功，这将创造一个新的市场，由于附加的驱动和控制电子设备，电子寻址显示器由于成本高而无法渗透。
