Title: Kazunari Okamura: Innovator in Display Technology
Introduction
Kazunari Okamura is a notable inventor based in Tenri, Japan. He has made significant contributions to the field of display technology, holding a total of 3 patents. His work primarily focuses on enhancing the functionality and stability of tablet devices.
Latest Patents
One of Okamura's latest patents is a display-integrated type tablet device that features a detection and hold circuit. This circuit outputs a reference signal proportional to an x-coordinate detection pulse from an X-coordinate signal amplifier. A delay element is incorporated to delay the reference signal, while an adder combines the x-coordinate detection pulse and the delayed signal. Comparators are utilized to obtain a coordinate detection pulse, ensuring that noise following the x-coordinate detection pulse is effectively removed. This innovation allows for stable coordinate detection, which is crucial for the performance of tablet devices.
Another significant patent involves a display-integrated type tablet device capable of detecting correct coordinates. In this invention, an induction voltage signal induced at a detection electrode of a detection pen is binarized. The number of pulses in the binary signal is counted, and this count is compared with the number of times the electrode is scanned. If the pulse count exceeds a certain threshold, an error detection alarm signal is triggered. This arrangement ensures that coordinates at the tip of the detection pen are detected accurately, even in the presence of external noise.
