Title: Innovations by Toshifumi Maeda
Introduction
Toshifumi Maeda is a notable inventor based in Toyama-ken, Japan. He has made significant contributions to the field of touch panel technology, holding a total of 3 patents. His innovative designs focus on improving the functionality and reliability of touch input devices.
Latest Patents
One of Maeda's latest patents is a touch panel input device that utilizes a transparent insulative liquid sealed between two transparent plates. These plates are coated with transparent conductor layers on their mutually facing surfaces. The roughened surface of at least one plate allows for a unique interaction when the device is tilted, ensuring that only the protrusions of the conductor layer make contact, thus maintaining a high contact resistance until a pressing operation is made. This design allows for a light pressing force to register a touch, enhancing user experience.
Another patent involves a touch-panel input device where two transparent conductive panels are separated by an elastic adhesive perimeter, creating a sealed gap filled with transparent insulative fluid. This fluid's refraction index is close to that of the panels, improving light transmittance. The small gap width enhances response time and prevents vacuum formation, while spacers reduce the chance of erroneous position commands. This design also provides better temperature variation tolerance and improves the overall reliability of the device.
