Abstract:
1. A display device comprising: a display panel having cathodes, gates and an anode, the cathodes and the gates being connected in matrix form; electron emitters provided on each of the cathodes and capable of performing electron emission with a voltage applied only between the cathodes and the anode, the display device being constructed to perform display by bringing pixels to dark states by applying a cut-off voltage between the cathodes and the gates to cut off electron emission from the electron emitters toward the anode; and a control unit for controlling the operation of a display panel driving circuit in order to complete, when a display completing signal is generated, application of the cut-off voltage or a driving voltage capable of providing a particular display state, after a predetermined time passes from the moment when a potential of the anode decreases below a threshold potential capable of causing electron emission from the electron emitters with the cut-off voltage or the driving voltage capable of providing the particular display state being applied between the cathodes and the gates.
