Electron-emitting device having multi-layer resistor |
摘要 |
An electron-emitting device employs a multi-layer resistor (46). A lower layer (48) of the resistor overlies an emitter electrode (42). A set of electron-emissive elements (54) overlie an upper layer (50) of the resistor. Each resistive layer extends continuously from a location below each electron-emissive element to a location below each other electron-emissive element. The two resistive layers are of different chemical composition. The upper resistive layer is typically formed with cermet. The lower resistive layer is typically formed with a silicon-carbon compound.
