Image sensing device

An imaging apparatus includes an electron emission array having electron sources arranged in matrix form, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film, wherein the control and drive circuit is further configured to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film in any one or more blanking periods excluding both a blanking period immediately following the given video signal output period and a blanking period immediately preceding a next video signal output period in which the one or more horizontal scan lines will be selected next time.

Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.

The image display device includes emittersconnected to a cathode electrode, a gate electrode, an anode electrode, transistors Trand Tr, and a capacitor.

Further, the field emission element includes an anode pixel formed by the anode electrode and a generally rectangular fluorescent body formed thereon and a plurality of wells, each being formed in the emitter electrode and the interlayer insulating layer in a form of a narrow elongated hole. Here, the wells are disposed within a generally rectangular electron emitting area and at least a majority of the wells are arranged parallel to each other, and a length direction of the majority of the wells is substantially normal to that of the fluorescent body and the electron emitting area.

A front glass cover is provided on an inner surface thereof with FECs constituted by cathode lines, insulating layers, emitters and gate lines so as to define light-permeable sections between FECs. A substrate is formed opposite to the light-permeable sections with anodes constituted by anode-lines and phosphor layers. Electrons emitted from the FECs impinge on the anodes, leading to luminescence of the phosphor layer, which is then observed through the light-permeable sections of the front glass cover.
