Title: Yasuhiro Kobayashi: Innovator in Display and Memory Technologies
Introduction
Yasuhiro Kobayashi is a notable inventor based in Gifu, Japan. He has made significant contributions to the fields of display technology and semiconductor memory devices. With a total of 4 patents to his name, Kobayashi's work has had a lasting impact on the industry.
Latest Patents
Kobayashi's latest patents include a gate driver for an active matrix liquid crystal display device. This innovative device is designed to reduce power consumption and eliminate switching loss, preventing surge when stepwise changing the gate pulse supplied to a gate line during selection. The device features a selection voltage supply circuit that includes a first power source for supplying a predetermined selection voltage and a second power source for supplying a voltage lower than the selection voltage by a predetermined value. This design ensures that voltage from the second power source is always applied to the output point of the selection voltage supply circuit, while voltage from the first power source is superimposed during a shorter time than the selection period, thereby applying stepwise gate pulses to the selected gate lines.
Another significant patent is for a semiconductor memory device with improved read characteristics. This device includes a plurality of memory cells, a reference cell, a comparator, and a discriminator. The comparator compares the actual signal equivalent to the current flowing in each memory cell with reference signals from the reference cell, outputting a comparison result signal during data reading operations. The discriminator then determines the value of data stored in each memory cell based on this comparison result.
