Title: Innovations of Peter Kipfer
Introduction
Peter Kipfer is a notable inventor based in Berneck, Switzerland. He has made significant contributions to the field of optical devices and liquid crystal technology. With a total of 2 patents, his work showcases innovative approaches to enhancing visual displays.
Latest Patents
Kipfer's latest patents include a Bragg reflection optical device and methods for the manufacturing thereof. This optical device utilizes at least one film of cholesteric liquid crystal to reflect specific wavelength bands from incident light. A key feature of this invention is the presence of a non-zero birefringence gradient within the film, which can be achieved by layering materials with varying birefringence coefficients. This gradient effectively removes lateral bands from the reflection spectrum, resulting in more brilliant and saturated colors, particularly enhancing the perception of red hues.
Another significant patent is related to a liquid crystal display device designed to form a color image display screen. This device consists of a transparent first substrate and a second substrate that creates a cavity for the liquid crystal film. The liquid crystal can switch between reflecting light of a predetermined color and becoming transparent, controlled by electrodes on the substrate surfaces. Additionally, a filter is incorporated to absorb visible neighboring wavelengths, ensuring the display's color accuracy.
