Title: Innovations of Katsumi Komiyama
Introduction
Katsumi Komiyama is a prominent inventor based in Isehara, Japan. He has made significant contributions to the field of liquid crystal technology, holding a total of 16 patents. His work has greatly influenced the development of advanced display technologies.
Latest Patents
Among his latest innovations are two notable patents. The first is a liquid crystal apparatus that includes a liquid crystal device with spontaneous polarization. This device causes a state change accompanied by polarity inversion within a specific response time. The drive means sequentially selects scanning signal lines during a scanning selection period, applying data signal voltages to the pixels along the associated scanning signal line. This method ensures that the scanning selection period is shorter than the response time for the liquid crystal, allowing for a desired state change while compensating for any voltage decrease caused by remaining polarity inversion.
The second patent is for a liquid crystal display apparatus that enhances motion picture quality. This improvement is achieved by strategically placing a non-display period based on the responsiveness of the liquid crystal and a backlight source. A sub-period is established within one frame period to display luminance corresponding to prescribed picture data, ensuring that the time integral of luminance does not exceed a certain threshold. Another sub-period is allocated for displaying lower luminance within the same frame period.
