Title: Teruyuki Fujii: Innovator in Key Interface and LCD Driver Circuits
Introduction
Teruyuki Fujii is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electronics, particularly in the development of key interface circuits and LCD driver circuits. With a total of 3 patents to his name, Fujii continues to push the boundaries of innovation in his industry.
Latest Patents
Fujii's latest patents include a key interface circuit with a reduced number of input terminals. This static key interface circuit features an input terminal connected to N key switches, where N is an integer greater than one. The key switches are biased at different potentials, which are supplied to the input terminal when the switches are closed. A multilevel detector within the circuit detects the potential of the input terminal and generates corresponding result data. Additionally, he has developed a dynamic key interface circuit that scans P rows of N key switches, utilizing a similar multilevel detector to increase the number of key switches connectable to a single input terminal by a factor of N. Another notable patent is his LCD driver circuit, which comprises a plurality of cascade-connected LCD drivers. This circuit can be activated to make a latch pulse signal input active on its trailing edge, allowing operation even when a corresponding clock pulse signal is input during the latch pulse signal period.
