Introduction

Manabu Fujiwara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of display technology, particularly in the development of current limiting circuits and methods for driving plasma display panels. With a total of 2 patents, his work has had a notable impact on the efficiency and performance of display devices.

Latest Patents

Fujiwara's latest patents include a current limiting circuit and a method for driving an address-display separated type AC plasma display panel. The current limiting circuit is designed to receive a video signal for a display panel that includes pixels, effectively limiting the current consumption of these pixels. This circuit features a first gain calculation circuit that computes a first gain based on the power consumption of the pixels, and a second gain calculation circuit that determines a second gain based on the first power consumption and its rate of change. A gain selection circuit then chooses between these gains to multiply with the video signal, followed by a gain multiplication circuit that applies this gain.

The second patent focuses on a method for driving an address-display separated type AC plasma display panel. This method ensures that wall charges can be formed sufficiently on both the scanning and sustaining electrodes, even when the width of the scanning pulse is reduced. The driving operations during the pre-discharge period remain consistent with conventional methods, while adjustments are made during the scanning period to enhance wall charge accumulation.
