Flat panel display device having planar field emission source

A method for driving a flat panel display, the flat panel display including a back plate, a gate electrode, a cathode electrode, a planar field emission source formed on the cathode electrode, a grid plate with a first grid electrode and a second grid electrode and having a plurality of apertures corresponding to a pixel area and a faceplate spaced from the grid plate and having a screen formed on one surface thereof facing the grid plate, the method comprising the steps of:

• applying scan voltage to the cathode electrode and data signal voltage to the gate electrode to form an electronic field by emitting electrons from the planar field emission source;
• applying focus signal voltage to the first grid electrode to converge the electrons at the apertures of the grid plate;
• applying deflection signal voltage to the second grid electrode to deflect the electrons passing through the apertures toward target phosphors;
• and
• applying anode signal voltage to the screen to accelerate the electrons to the screen.
