Latest Patents

Hammerschmidt's latest patents include a method for producing optical compensation films through a carrier-web-casting process. This method involves coating one or more first and second layers onto a carrier substrate and stretching them simultaneously. The first layers consist of a polymer with an out-of-plane birefringence not more negative than -0.005 and not more positive than +0.005. The second layers contain a polymer with a more negative or positive out-of-plane birefringence. The resulting optical compensation film exhibits an overall in-plane retardation greater than 20 nm and an out-of-plane retardation that is either more negative than -20 nm or more positive than +20 nm.

Another significant patent involves a multilayer compensator that utilizes specified Tg material as a birefringent layer. This multilayer compensator comprises one or more polymeric first layers and second layers. The first layers include a polymer with an out-of-plane birefringence between -0.005 and +0.005, while the second layers consist of an amorphous polymer with a more extreme out-of-plane birefringence. The overall in-plane retardation of this multilayer compensator is also greater than 20 nm, with specific conditions for the glass transition temperature (Tg) of the amorphous polymer.
