    Abstract: A driving apparatus comprises a scanning driver circuit connected to scanning electrodes and a signal driver circuit connected to signal electrodes. The sccanning driver circuit comprises: a drive signal voltage generating unit which includes a first signal voltage generating unit for generating a scanning selection signal voltage supplied to a first bus, and a second signal voltage generating unit for generating a scanning nonselection signal voltage supplied to a second bus, a switching circuit unit for selectively supplying the scanning selection signal or the scanning nonselection signal to a scanning electrode, and a switching signal generating unit for supplying a switching control signal to the switching circuit unit.

    Abstract: An electron emitting device includes a first electrode located on a substrate (1), an insulating layer located on the first electrode (2), and a second electrode (3) located on the insulating layer. Various examples are described. In one example, the second electrode has a first surface and a second surface, which are substantially vertical to a direction that the first electrode and the insulating layer are laminated. The first surface of the second electrode is in contact with the insulating layer. A higher potential than that applied to the second electrode is applied to the first electrode to emit an electron from the second surface.

    Abstract: An electron source emits electrons as a function of input signals. The electron source comprises a substrate (1), a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes (5,6) and a thin film (4) including an electron emitting region (3) and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. Each pixel unit is irradiated by at least two electron beams emitted from the respective electron emitting regions which are juxtaposed with interleaving the higher potential device electrode therebetween and a gap interval W in the juxtaposing direction of which satisfies equation (1) below: K2 x 2H(Vf/Va) ≥ W/2 ≥ K3 x 2H(Vf/Va) where K2 = 1.25 +/- 5.05, K3 = 0.35 +/- 0.05, H is the distance between the surface-conduction electron-emitting devices and the image-forming member, Vf is the voltage applied to the surface-conduction electron-emitting device and Va is the voltage applied to the image-forming member.
