Electron-beam generating device having plurality of cold cathode elements, method of driving said device and image forming apparatus applying same

The invention relates to a conductive to drive a electron-emitting supply method and device, a leakage current of the non-uniform efficient current distribution device for obtaining is the high image display in the cold-cathode element is a stop block. A digital video signal input of the shift register, and realizes to each wire of the serial of parallel conversion. The line of image data the conversion are locked by a latch both are provided with a voltage regulator circuit; and a through the corresponding row are connected to a display lower cold-cathode element.
