Title: Innovations by Shinichiro Hashimoto
Introduction
Shinichiro Hashimoto is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of plasma display technology. With a total of 10 patents to his name, Hashimoto has been instrumental in advancing display technologies that enhance image quality and performance.
Latest Patents
Hashimoto's latest patents include a plasma display device and a plasma display panel driving method. The plasma display device aims to stabilize the generation of address discharge and improve the gradation characteristics of display images. Key elements of this invention include a plasma display panel, a sustain pulse generating circuit, and a ramp voltage generating circuit. The ramp voltage generating circuit consists of a first ramp voltage generating circuit, a second ramp voltage generating circuit, and a switching circuit. The first ramp voltage generating circuit generates a first ramp voltage that gently increases during the initializing period. The second ramp voltage generating circuit produces a second ramp voltage that increases with a gradient gentler than that of the rising edge of a sustain pulse and steeper than that of the first ramp voltage at the end of each sustain period. The switching circuit halts the operation of the second ramp voltage generating circuit immediately after the second ramp voltage reaches a predetermined electric potential. In at least one sustain period of one field, no sustain pulse is generated, but the second ramp voltage is produced.
Another notable patent involves a plasma display device featuring a protective layer that includes a base protective layer and a particle layer. This device utilizes a crystal particle made of MgO single crystal, which exhibits a desired cathode luminescence emission spectrum. The driving method during the initializing period involves applying a voltage that gradually increases from a first voltage to a second voltage to a second electrode, followed by a gradual decrease from a third voltage to a fourth voltage.
