The area of display devices has experienced extremely rapid growth in recent years and these advances show no sign of declining. One of the major developments in this field has been the use of lasers for various microfabrication tasks. This paper describes some techniques which have been developed using excimer lasers for the production of novel microstructures in polymer materials. Examples of the types of microstructures which are produced are presented and their applicability for display device applications is outlined. Forthcoming developments in the laser manufacture of displays are discussed.
Non‐birefringent photopolymer materials incorporated into Liquid Crystal Display (LCD) assemblies can improve performance characteristics such as angle of view (AOV), definition, and brightness. Such improvements can be made both to displays that incorporate permanent backlights, and also to those that rely in part on ambient lighting. This paper describes the optical characteristics of some non‐birefringent photopolymer materials, their incorporation into displays, and the consequent improvement in display performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
