Title: Innovations of Mitsuharu Nakazawa
Introduction
Mitsuharu Nakazawa is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of liquid-crystal display technology. With a total of 3 patents to his name, Nakazawa's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a drive circuit for liquid-crystal displays. This innovation features a simple configuration that is not susceptible to the characteristics of the device. The liquid-crystal drive circuit includes an auxiliary capacitor, which applies a first voltage to a driving buffer. It temporarily accumulates an output voltage of the driving buffer in the auxiliary capacitor and applies a voltage produced by subtracting the potential at the auxiliary capacitor from a second voltage to the driving buffer. The output of the driving buffer is then applied onto a data bus. Another significant patent is for a liquid crystal display device and the process for its production. In this patent, a capacitor electrode is formed simultaneously with drain bus lines. This capacitor electrode is electrically connected to the contact of two TFTs through the medium of a contact hole. An interlayer insulating film is formed on the entire face, and a black matrix of light-blocking metal film is formed on the interlayer insulating film to overlie the channel parts and the contacts of the TFTs and the capacitor electrode. Together, these components form a capacitor.
