Title: Hiroshi Tanaka: Innovator in Touch Panel Technology
Introduction
Hiroshi Tanaka is a prominent 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 have paved the way for advancements in user interface technology.
Latest Patents
Tanaka's latest patents include 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 of the transparent plates allows for a unique interaction when the device is tilted. The insulative liquid settles downward, enabling the upper conductor layers to make contact only at the protrusions, ensuring that the overall contact resistance remains high enough to avoid misinterpretation as a pressing operation. When a pressing action occurs, the liquid flows into the depressions created by the roughened surface, allowing for a reliable and responsive touch experience.
Another notable patent involves a touch-panel input device where two transparent conductive panels are separated by an elastic adhesive perimeter, forming a sealed gap filled with transparent insulative fluid. This design enhances light transmittance and improves response time while preventing vacuum formation in the gap. The position detection circuit connected to the panels accurately determines the coordinate position of applied pressure points, ensuring precision in user interactions.
