Latest Patents
Kouji Ooae's latest patents focus on innovative liquid crystal display materials and methods. One of his inventions provides a novel liquid crystal display material that boasts an excellent contrast ratio. This invention utilizes a polymer in which liquid crystal is dispersed in a dissolvable or phase-separable state. The liquid crystal dissolves in the polymer at high temperatures and separates at low temperatures, allowing for a contrast ratio (B/A) of a reflectance (A) of the display material cooled from the dissolution state at a rate of 10°C/sec and a reflectance (B) cooled at a rate of 4°C/sec to be not less than 2. This technology enables the maintenance of an image-forming state by controlling the cooling rate from the dissolution state.
Another significant patent involves a polymer-dispersed liquid crystal display element designed to prevent cross-talk effects while allowing for simple matrix drive. This element employs a polymer with a dielectric constant greater than that of the liquid crystal, ensuring that the volumetric content of the liquid crystal does not exceed that of the polymer.
