Title: Fujio Matsu: Innovator in Display Technology
Introduction
Fujio Matsu is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of display technology, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of liquid crystal displays.
Latest Patents
Matsu's latest patents include a display device that features a liquid crystal panel, a controller, a common driver, and a segment driver. This innovative design allows the common driver to operate on a high power supply voltage, outputting row driving waveforms with relatively high voltage levels. In contrast, the segment driver functions on a low power supply voltage, producing column driving waveforms with lower voltage levels. This construction eliminates the need for both drivers to be high withstand voltage integrated circuit devices. Another notable patent is the gray shade driving device for liquid crystal displays. This device employs first circuitry to apply row signals represented by orthonormal functions to row electrodes, while second circuitry performs dot product computations between these functions and pixel data. This results in a column signal that is synchronized with the scanning process, enhancing the display's performance.
