Title: Innovations in Liquid Crystal Displays by Inventor Youichi Murayama

Introduction

Youichi Murayama is a distinguished inventor based in Tokyo, Japan, known for his significant contributions to the field of liquid crystal display technology. With a portfolio that includes five notable patents, Murayama has demonstrated a keen ability to innovate and enhance display technologies, particularly through anisotropic reflection electrodes.

Latest Patents

Murayama's latest inventions revolve around advanced liquid crystal displays. One of his prominent patents describes a reflection electrode with an undulated shape, which features a normal direction distributed unevenly to a specific azimuth angle. The innovation includes openings formed in areas with a tilt angle between 0 to 2 degrees and/or 10 degrees or higher. This design alters the molecular alignment mode of the liquid crystal layer, leading to increased output light intensity in both reflection and transmission modes. Furthermore, the balance of colors in transmission mode is determined by the area of these openings in pixels of each color, with a higher color temperature set in transmission mode compared to reflection mode. This results in a semi-transmission type liquid crystal display that boasts excellent visibility in both modes.

Another patent mirrors these elements, emphasizing the anisotropic reflection electrode's undulated shape and its varying light reflection properties based on azimuth angles. By changing the retardation of the liquid crystal layer through different molecular alignment modes between the openings and the electrode, Murayama significantly enhances light output.
