Latest Patents
Yamamura holds a patent for a field emission display device. This device operates on a high anode voltage to effectively accelerate emitted electrons towards the anode, resulting in high brightness without leakage of glowed light. The design includes cone emitters formed on a cathode electrode, which is laid on a cathode substrate. An insulating layer and first gate electrodes are created on areas without emitters, while a second insulating layer is placed over the first gate electrodes. The second gate electrodes, or focusing electrodes, are formed with openings above the first gate electrodes. Multiple lines of emitters are arranged in parallel within the emitter area, corresponding to one pixel. The emitters are aligned with the openings, and an anode voltage ranging from 2kV to 5kV is applied to the anode electrode. The electrons emitted are focused by the focusing electrodes and directed towards the anode electrode.
