Latest Patents
Hashiguchi's latest patents include a plasma display apparatus and a display device with a method of driving the same. The plasma display apparatus patent describes a unique waveform of a driving voltage supplied from a driver. This waveform includes a sustaining period where a sustaining pulse is alternately applied to scanning electrodes and sustain electrodes to maintain discharge. Additionally, it features an erasing period where a ramp voltage pulse, differing in polarity from the sustaining pulse, is applied to a different electrode. This innovation effectively prevents false discharge, ensuring a stable image display.
The second patent focuses on a display device and its driving method. It outlines a process where a heating current is supplied to a cathode during periods when electron beam emission to a photo-emissive screen is inhibited. When the emission is enabled, the heating current supply is interrupted, allowing the cathode's potential to be varied with a video signal. This method ensures uniform electron beam emission along the cathode, enhancing the quality of the displayed image.
