Akio Niwa

Title: Akio Niwa: Innovator in Display Technology

Introduction

Akio Niwa is a notable inventor based in Takatsuki, Japan. He has made significant contributions to the field of display technology, holding a total of 3 patents. His work has been instrumental in advancing the functionality and efficiency of plasma displays and video signal conversion devices.

Latest Patents

One of his latest patents is for a plasma display that features a latch failure detecting function. This innovation includes a test pattern generation circuit that outputs a test pattern during a clock phase adjustment period. A flip-flop circuit latches the test pattern at the fall of a shift clock and outputs it as a test pattern. Additionally, a latch miss detection circuit outputs a latch miss detection signal indicating the presence or absence of a latch miss generation according to the test pattern and a delay shift clock. A clock phase controller delays the shift clock based on the latch miss detection signal, thereby outputting a delay shift clock.

Another significant patent by Niwa is related to a video signal conversion device and method. This invention involves storing video data of a field necessary for I/P conversion and scanning line conversion in a field memory part. Vertical frequency conversion is performed by a memory control processing part, while I/P conversion is executed by an I/P conversion processing part. Scanning line conversion is handled by a scanning line conversion part, and horizontal pixel conversion is performed by a horizontal pixel conversion processing part using the data stored in the field memory part. A synchronous processing part supplies a prescribed clock, along with horizontal and vertical synchronizing signals to each block, allowing a single system to perform vertical frequency conversion, I/P conversion, scanning line conversion, and horizontal pixel conversion.
