Title: Fumio Shida: Innovator in Liquid Crystal Display Technology

Introduction

Fumio Shida is a notable inventor based in Suwa, Japan. He has made significant contributions to the field of liquid crystal display technology. With a total of 2 patents, his work has had a lasting impact on the industry.

Latest Patents

Fumio Shida's latest patents include a circuit for driving an active matrix liquid crystal display panel. This innovative circuit is designed to operate with M rows and N columns, utilizing video digital data of K bits. The design features thin film transistors that form pixels at the intersections of the rows and columns. An analog switch, capable of ON and OFF states, receives a video voltage and a control signal, selectively outputting the video voltage to each column. The video voltage varies in level, sequentially increasing from the OFF state at least once during each horizontal scanning period. The control mechanism processes the K bit digital input data to produce a control signal that regulates the ON state of the analog switch.

Another patent by Shida also focuses on a circuit for driving a liquid crystal display panel. Similar to the previous invention, it involves M rows and N columns, with the addition of a discharge power supply voltage. This circuit also utilizes an analog switch to output either the video voltage or the discharge power supply voltage to each column based on the control signal. The innovative design ensures that the video voltage varies in level, enhancing the display's performance.
