Title: Hirotomo Oniwa: Innovator in Display Technology
Introduction
Hirotomo Oniwa 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 innovative designs have advanced the functionality and efficiency of display devices.
Latest Patents
One of his latest patents is a display device that includes a liquid crystal panel, a controller, a common driver, and a segment driver. The common driver is powered by a high power supply voltage and outputs row driving waveforms with predetermined voltage levels that are relatively high. In contrast, the segment driver operates on a low power supply voltage, outputting column driving waveforms with relatively low voltage levels. This design eliminates the need for both the segment and common drivers to be high withstand voltage integrated circuit devices.
Another notable patent is the gradative driving apparatus of a liquid crystal display panel. This device features a vertical driver that applies row signals represented by a set of orthogonal functions supplied by an orthogonal function generator. The horizontal driver applies column signals based on the results of a dot product computation, synchronizing with group-sequential scanning. A frame memory stores pixel data for each frame in divided bit form, enhancing the display's performance.
