Title: Kei Oyobe - Innovator in Liquid Crystal Display Technology
Introduction
Kei Oyobe is an inventor based in Osaka, Japan. He has made significant contributions to the field of liquid crystal display technology. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.
Latest Patent Applications
One of his notable patent applications is for a "LIQUID CRYSTAL DISPLAY DEVICE, AND COLOR REPRODUCTION METHOD THEREOF." This device features a backlight and a liquid crystal panel positioned on the light-emitting surface side of the backlight. The design includes at least one blue LED for emitting blue light and at least one white LED for emitting white light. Each pixel of the liquid crystal panel is equipped with a red filter that transmits light in the red wavelength region, a green filter for the green wavelength region, and a white filter that transmits light across all wavelength regions.
Another application is for a "DISPLAY PANEL AND DISPLAY DEVICE." This invention includes a display part that detects external input through a photo sensor. It consists of an active matrix substrate with the photo sensor, an opposite substrate, a liquid crystal layer between the two substrates, and a protective plate covering the opposite substrate. A non-flat portion is formed on the protective plate to enhance the recognition of contact points from outside.
Conclusion
Kei Oyobe's work in liquid crystal display technology showcases his innovative spirit and dedication to advancing display devices. His latest patent applications reflect his commitment to improving color reproduction and user interaction in display technologies.
