    Abstract: A cathode ray tube having a cathode comprising a sleeve with a heater installed therein and a base metal with a side portion covering an outer circumference of the sleeve and an upper surface portion covering an upper side of the sleeve, satisfies the following formula: tSnulltB1null2tS, wherein tB1 is a thickness of the side portion of the base metal and tS is a thickness of the sleeve. Therefore, the warm-up time taken for formation of an image after power is applied to the cathode ray tube can be shortened.

    Abstract: Apparatus and method are provided for using a multi-element field emission cathode in a color cathode ray tube. The field emission cathode may have from four to ten field emission arrays linearly arranged. The arrays are preferably formed from carbon-based material. An electron gun assembly focuses electron beams from each array on to a phosphor stripe or dot on the screen of the cathode ray tube. Deflection apparatus moves the beam from each field emission array according to clock signals. Clock signals also turn on or turn off voltage to contacts controlling electron current from the array. Values of voltage applied, determined by a video signal, determine the intensity of electron current from each array, which controls the intensity of the light emitted by each color stripe or dot of phosphor on the phosphor screen.

    Abstract: In a field emission-type electron source (10), a strong field drift layer (6) and a surface electrode (7) consisting of a gold thin film are provided on an n-type silicon substrate (1). An ohmic electrode (2) is provided on the back surface of the n-type silicon substrate (1). A direct current voltage is applied so that the surface electrode (7) becomes positive in potential relevant to the ohmic electrode (2). In this manner, electrons injected from the ohmic electrode (2) into the strong field drift layer (6) via the n-type silicon substrate (6) drift in the strong field drift layer (6), and is emitted to the outside via the surface electrode (7). The strong field drift layer (6) has: a number of semiconductor nanocrystals (63) of nano-meter order formed partly of a semiconductor layer configuring the strong field drift layer (6); and a number of insulating films (64) each of which is formed on the surface of each of the semiconductor nanocrystals (63) and each having film thickness to an extent such that an electron tunneling phenomenon occurs.
