Title: Innovations by Ryohei Hatta

Introduction

Ryohei Hatta is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of input signal correction devices, holding two patents that showcase his innovative approach to reducing power consumption in display technology.

Latest Patents

Hatta's latest patents include advanced input signal correction devices designed to enhance the performance of various display panels. The first patent describes an input signal correction device that features an input circuit, extension/degeneration circuit, separation/recovery circuit, and delay adjustment circuit operating at frequency f. It also includes a demura circuit operating at frequency f/2 and an adder circuit. This device is capable of increasing the input signal cycle length by a factor of 2 or degenerating the input signal to ½, based on a control signal. The demura circuit outputs a correction signal that adjusts the preprocessing signal from the extension/degeneration circuit. The separation/recovery circuit further refines the output by reducing the correction signal cycle length to ½ or maintaining the same differential signal over two cycles. The delay adjustment circuit introduces a delay to the input signal, while the adder circuit combines the differential signal with the delay signal to produce the final output.

The second patent also focuses on an input signal correction device, which includes similar components such as an input circuit, extension circuit, degenerate circuit, separation circuit, recovery circuit, and delay adjustment circuit. This device operates at an operating frequency f, with the demura circuit functioning at frequency f/2. The extension circuit extends the period of the R and B input signals by a factor of 2, while the degenerate circuit processes the G input signal. The demura circuit corrects the preprocessing signals and outputs correction signals. The separation circuit reduces the period of the R and B correction signals to ½, and the recovery circuit processes the G correction signal similarly. The delay adjustment circuit manages the timing of input and output signals, and the adder circuit combines the differential signals with the delay signals to produce the output signals.
