Title: Innovations of Inventor Chen Cai
Introduction
Chen Cai is a notable inventor based in Hartsdale, NY (US). He has made significant contributions to the field of liquid crystal display technology. With a total of 2 patents, his work has advanced the understanding and application of liquid crystal materials in display devices.
Latest Patents
Chen Cai's latest patents include a vertical aligned liquid crystal display and a method using dry deposited alignment layer films. This innovative liquid crystal display device features a first substrate with a dry alignment film deposited over it. A second substrate is coupled to the first substrate, with the dry alignment film in between, forming a cell gap filled with liquid crystal material. The dry alignment film enables a truly vertical alignment of the liquid crystal molecules, allowing them to form an angle of substantially 90 degrees relative to the substrate. This process can be enhanced with a ridge and fringe field method to create multidomain Vertical Alignment (VA) Liquid Crystal Displays (LCDs) that offer wide viewing angles. Another patent involves a vertically aligned pi-cell LCD, which includes a layer of liquid crystal material between homeotropic alignment layers. This design allows for a unique orientation of the liquid crystal molecules in response to an electric field, enhancing the display's performance.
