Title: Shigeki Tamai: Innovator in Liquid Crystal Technology
Introduction
Shigeki Tamai is a prominent inventor based in Nara, Japan, known for his significant contributions to liquid crystal technology. With a total of 15 patents to his name, Tamai has made remarkable advancements in the field of liquid crystal displays.
Latest Patents
Tamai's latest patents include a method of driving liquid crystal panels and a liquid crystal display apparatus. The liquid crystal display apparatus utilizes an active-matrix liquid crystal panel driven by the line reversal driving method. This innovative approach involves a common driver that AC-drives one of a pair of electrodes in each pixel of the liquid crystal panel. An adding circuit is employed to obtain the sum of multiple gradation components, which helps in determining the gradations of the pixels at predetermined horizontal intervals. Additionally, a voltage setting portion in the source driver corrects the reference voltage difference based on the sum, allowing for the selection of appropriate gradation voltages to be applied to the data lines in the liquid crystal panel.
Another notable patent is the liquid-crystal-panel driver IC package and liquid crystal panel module. This invention allows for compact mounting of the driver IC package on the liquid crystal panel without the need for fixing jigs. The design includes laminated glass substrates that seal liquid crystals and form a step region, where multiple driver ICs are arrayed for efficient operation.
