Title: The Innovations of Tokutarou Kusada
Introduction
Tokutarou Kusada is a notable inventor based in Tenri, Japan. He has made significant contributions to the field of liquid crystal display technology. With a total of 2 patents, his work has advanced the capabilities of display devices, particularly in television signal reception.
Latest Patents
Kusada's latest patents include a liquid crystal display device and a driving method thereof. This innovative device enhances the interlace scanning method for receiving television signals. By increasing the number of rows of pixels and scan signal lines on the liquid crystal panel, it matches the number of valid scan lines of one frame of television signals. The original video signals are compressed to half their size, with interpolating signals added to create pseudo video signals. The shift register operation of both the scan driver and the segment driver is executed at double the speed of conventional devices. Additionally, the timing of the shift register operation is controlled to alternate between even and odd fields, allowing for a seamless display that adheres to the interlace scanning method.
Another significant patent is a device and method for driving a liquid crystal panel. This circuit utilizes multiple source drivers and includes a separate line memory circuit for transmitting color signals to both even and odd line source drivers. Each line memory circuit is designed to form digital color signal trains based on the color order of the corresponding source lines. This innovative approach allows for efficient processing and transmission of color signals, enhancing the overall performance of liquid crystal displays.
