Title: Erich C Walter: Innovator in Display Technology
Introduction
Erich C Walter is a notable inventor based in Woodbury, MN (US). He has made significant contributions to the field of display technology, particularly in the development of cholesteric liquid crystal displays and electrochromic devices. With a total of 2 patents to his name, Walter's work has advanced the capabilities of modern display systems.
Latest Patents
Walter's latest patents include "Fast transitions of large area cholesteric displays" and "Electrochromic device." The first patent describes a gray scale drive scheme for passive matrix displays, specifically cholesteric liquid crystal displays. This innovative approach allows the display to appear black before an image is written by first driving the pixels to a homeotropic state and then to a focal conic state. The drive scheme resets pixels by driving selected pixels back to a homeotropic state, utilizing a combination of selecting and non-selecting row voltage signals with column voltage signals to effectively write an image.
The second patent, the "Electrochromic device," involves an electrode that features a transparent substrate with a conductive layer and an electrode layer made of doped tin oxide nanoparticles and an organic binder. This electrode layer is designed to be transparent, enhancing the functionality of electrochromic articles that incorporate such electrodes.
