Title: Munehiro Haraguchi: Innovator in Liquid Crystal Display Technology
Introduction
Munehiro Haraguchi is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of liquid crystal display (LCD) technology, holding a total of 6 patents. His innovative work has paved the way for advancements in display quality and manufacturing processes.
Latest Patents
Haraguchi's latest patents include a liquid crystal display device and a process for its production. In one of his notable inventions, a capacitor electrode is formed simultaneously with drain bus lines. This capacitor electrode is electrically connected to the contact of two thin-film transistors (TFTs) through a contact hole. An interlayer insulating film is then formed on the entire face, along with a black matrix of light-blocking metal film, such as titanium, which overlies the channel parts and contacts of the TFTs and the capacitor electrode. This configuration allows the capacitor electrode, the interlayer insulating film, and the black matrix to jointly form a capacitor.
Another significant patent involves an active matrix liquid crystal display and its driving method. This invention features a liquid crystal layer, first and second electrodes, and a third electrode. The liquid crystal layer is inserted between the first and second electrodes to define liquid crystal cells. The third electrode is capacitively coupled with one of the first and second electrodes. A correction voltage is applied to the third electrode to correct distortion in the driving waveform, thereby maintaining an effective voltage across the liquid crystal cells and improving display quality. This innovation effectively corrects common voltage distortion and prevents crosstalk.
