Title: The Innovative Contributions of Bertil Helgee

Introduction

Bertil Helgee, an accomplished inventor based in Västra Frölunda, Sweden, has made significant contributions in the field of electro-optic devices. With a portfolio of five patents, his work primarily focuses on enhancing liquid crystal technology, which has far-reaching implications in imaging and display applications.

Latest Patents

Helgee's most recent patent includes a groundbreaking liquid crystal device designed for the generation and fast switching of high contrast images. This innovative electro-optic device incorporates antiferroelectric liquid crystals with a large molecular tilt of approximately 45 degrees, situated between two flat glass or polymer substrates. The design employs crossed polarizers, allowing for the control of light passage depending on whether an electric field is applied. In the absence of the field, the device remains isotropic, preventing light transmission. Once engaged, the electric field transitions the state from optically isotropic to birefringent ferroelectric, enabling high-contrast image generation and rapid switching, as well as creating various grey scale levels.

Another notable patent involves the development of a polymer used as an alignment layer in liquid crystal devices. This polymer is characterized by a unique structure that lacks directly coupled ring formations, with side-chains consisting of substituted or unsubstituted phenyl groups linked through various coupling units. The polymer exhibits dielectric anisotropy, which is essential for the effective operation of liquid crystal displays.
