发明名称 Field emission device and field emission display
摘要 A field emission display and display driving method, wherein the display includes a plurality of cathode lines arranged in a first direction in parallel; a plurality of gate lines arranged in a second direction in parallel, perpendicular to the first direction and isolated from the cathode lines; a field emission device at a cross point of one of the cathode lines and one of the gate lines, including an anode, an emitter connected to the one of the cathode lines, and a gate connected to the one of the gate lines; a scanning circuit configured to apply a scanning signal to one of the gate lines; and a modulating circuit configured to form a modulated signal synchronized with the scanning signal from an image signal having intensity information. The modulated signal has a plurality of pulse width modulated waveforms, each having a duty cycle indicative of the brightness of a corresponding picture element of the image signal, wherein successive waveforms have a level transition (high to low or low to high) that is inverted from the level transition of the immediately prior waveform, each of the waveforms beginning a period at one of two signal levels (high or low) and ending the period at the other (low or high) of the two signal levels. In one embodiment, a first cathode line has applied thereto a first pulse width modulated signal which begins the period at one of the two signal levels, and simultaneously a second cathode line has applied thereto a second pulse width modulated signal which begins the period with the other of the two signal levels.
