Title: Masanori Ookawa: Innovator in Liquid Crystal Display Technology

Introduction

Masanori Ookawa is a prominent inventor based in Katsuura, Japan. He has made significant contributions to the field of liquid crystal display (LCD) technology. With a total of 2 patents, his work has advanced the functionality and reliability of LCD devices.

Latest Patents

Masanori Ookawa's latest patents include innovative designs for LCD devices. One of his patents describes an LCD device with pixels that incorporate first and second transistors of different sizes and connections. In this design, the first transistor is larger than the second, with channel widths and gate widths that are also larger. This configuration allows the first transistor to be closer to the drain signal line, ensuring that it operates normally while the second transistor remains in a floating state. In the event of an abnormality in the first transistor, it can be disconnected from the drain signal line, allowing the second transistor to take over through a repair line.

Another notable patent involves a liquid crystal display device that features a spare transistor. This design includes a normal transistor connected to a data signal line and a pixel electrode, along with a spare transistor in a floating state. If the normal transistor experiences an operational abnormality, it is cut off from the data signal line and the pixel electrode. Subsequently, the spare transistor is connected to both the data signal line and the pixel electrode via repair lines, enhancing the reliability of the display.

Career Highlights

Throughout his career, Masanori Ookawa has worked with leading companies in the display technology sector. He has been associated with Hitachi Displays, Ltd. and Panasonic Liquid Crystal Display Co., Ltd.
