Title: Komei Asai: Innovator in Liquid Crystal Display Technology
Introduction
Komei Asai is a prominent inventor based in Hirakata, Japan. He has made significant contributions to the field of liquid crystal display technology, holding a total of 5 patents. His innovative work has paved the way for advancements in image display apparatuses.
Latest Patents
One of Asai's latest patents is an image display apparatus of liquid crystal valve projection type. This apparatus comprises an electro-optic element and a Schlieren optical system. The electro-optic element features a liquid crystal layer that possesses dielectric and optical anisotropy. An electric field with a spatial intensity distribution, corresponding to an image signal, is applied to the liquid crystal, resulting in the formation of a spatially phase-modulated phase diffraction grating. This technology allows for the projection of an enlarged image with a constant light diffraction angle, enhancing the light utilization efficiency.
Another notable patent is an apparatus for driving a liquid crystal display device. This device includes a liquid crystal layer with electrodes on its two opposite surfaces. It features means for applying a first signal to designate the electrode position and a higher frequency voltage signal to one surface's electrodes. The other surface's electrodes receive an input signal along with the higher frequency signal. This innovative approach allows for temperature compensation by adjusting the magnitude or frequency of the voltage signal based on the temperature level.
