Embodiment approach 1

[0110] The driving method of the electron emission element of Embodiment 1 of the present invention is as follows figure 1 , figure 2 The scheme shown in is also an electron emission element having a two-terminal structure having a cathode (cathode electrode) and an anode (anode electrode) at a distance of only H above the cathode as an electron emission element.

[0111] That is, the electron emission element of this embodiment, such as figure 2 As shown, a predetermined voltage can be applied by a voltage source 91 between a cathode electrode 93 formed of a carbon fiber aggregate 94 constituting an electron emission element and a counter electrode (anode electrode) 95 disposed at a position facing it. Va. Moreover, the driving method of the electron emission element of the present embodiment is to apply the maximum voltage between the cathode electrode 93 and the counter electrode 95 before the start of driving (typically, at the time of manufacture), that is, the maxim...

Embodiment approach 2

[0116] use Figure 6 and Figure 7 The electron emission element of this embodiment will be described. The electron emission element of this embodiment is an electron emission element of a so-called 3-terminal structure. and also, Figure 7 is a typical cross-sectional view showing how the electron-emitting element of this embodiment is driven, Figure 6 is a typical plan view for explaining part of the cathode electrode 13 and the control electrode 12 ( Figure 6 (a)), and Figure 6 (a) A typical cross-section between A-A' ( Figure 6 (b)).

[0117] Both the control electrode 12 and the cathode electrode 13 are arranged at intervals on the substrate 11 . Moreover, the top end (marked with reference numeral 64) of the carbon fiber assembly 14 disposed on the cathode electrode 13 is located closer to the anode electrode 62 than the control electrode 12 (refer to Figure 7 ).

[0118] In this example, the electron emission from the carbon fiber aggregate 14 is started b...

Embodiment approach 3

[0188] Next, as Embodiment 3 of the present invention, an electron source driving method for arranging a plurality of electron emission elements having various kinds of the above-mentioned carbon fiber aggregates and a manufacturing method for reducing the difference in electron emission characteristics of each electron emission element (characteristic adjustment step) were carried out. illustrate.

[0189] Figure 14 It is an example of an electron source in which a plurality of electron emission elements produced by the above method are arranged in a matrix. Figure 15 typically expressed Figure 14 The section between A-A' in. As for the arrangement shape of the electron emission elements of the present invention, it is not limited to Figure 14 shape.

[0190] Figure 14 In the example, the column direction wiring 161 is connected to the control electrode 165 of the element ( Figure 6 , 7 Components denoted by number 12 in). The row-direction wiring 162 is electri...

Abstract

In a driving method for an electron-emitting device in which an electron-emitting member made of an aggregate of carbon fibers is made to emit electrons by a voltage being applied between a cathode electrode on which the electron-emitting member is formed and a counter electrode disposed in opposition to the cathode electrode, a driving voltage V smaller than a maximum applied voltage Vmax is applied between the cathode electrode and the counter electrode to drive the electron-emitting device, the maximum applied voltage Vmax being a maximum voltage applied between the cathode electrode and the counter electrode before the start of driving.

Description

technical field [0001] The present invention relates to a driving method of an electron emission element using carbon fibers, a driving method of an electron source, a manufacturing method of the electron source, and an image display. Background technique [0002] Conventionally, an electric field emission type (hereinafter abbreviated as FE type) is known as an electron emission element. [0003] Regarding the FE type electron emission element, it has been published in J. Appl. Phys. Vol. 47, No. 12, p. 5248 (1997) and the like. [0004] In recent years, fibrous carbon materials such as carbon nanotubes having diameters of a nanometer size have been paid attention to in the above-mentioned FE-type electron emission materials. [0005] Carbon nanotubes themselves are described, for example, in Nature, 354, (1991) 56. [0006] Aggregates of carbon fibers are disclosed in, for example, JP-A-2000-095509 and Applied Physics Letters 76(2000) pp.2367-2369. [0007] And, just ca...
