Introduction

Qingbing Wang is a notable inventor based in Kent, OH (US), recognized for his contributions to the field of liquid crystal technology. With a total of 2 patents, he has made significant advancements that enhance the performance and durability of liquid crystal devices.

Latest Patents

One of his latest patents focuses on "Polymer enhanced liquid crystal devices built with rigid or flexible substrates." This invention describes a liquid crystal device that consists of a pair of opposed substrates defining a cell gap. Each substrate features an electrode on a surface facing the other substrate, with a plurality of spacers randomly disposed in the cell gap. These spacers extend from one substrate to the other, and crucially, a polymerization enhancing or initiating compound is not placed on the surface of the spacers. The invention also includes polymer columns that immobilize the spacers in the cell gap, providing stability against mechanical pressure. This innovation enables the fabrication of durable, flexible liquid crystal display devices using plastic substrates, making them suitable for portable and handheld applications.

Another significant patent by Wang is related to "Liquid crystal alignment using electron beam exposure." This apparatus is designed to produce an alignment surface on a substrate of a liquid crystal display. It utilizes a collimated electron beam to raster across the substrate while it is positioned at a preselected angle. This method enhances the alignment of liquid crystals, improving the overall performance of the display.
