Problems solved by technology

[0007] However, a typical field emission display element needs to provide a high voltage between the cathode and the anode, which is usually higher than 1000 volts, which makes the power consumption of the element extremely large

Abstract

A field emission display device (1) includes a cathode plate (20), a resistive buffer (30) in contact with the cathode plate, a plurality of electron emitters (40) formed on the buffer, and an anode plate (50) spaced from the electron emitters. Each electron emitter includes a rod-shaped first part (401) and a conical second part (402). The buffer and first parts are made from silicon oxide. The combined buffer and first parts has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest the anode plate. The second parts are made from niobium. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse an interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage is needed.

Description

【Technical field】 [0001] The invention relates to a field emission display element, in particular to a field emission display element which realizes low energy consumption by means of nanoscale electron emission units. 【Background technique】 [0002] In recent years, flat panel displays have developed rapidly and have been widely used in fields such as personal computers and consumer electronics products. At present, the most widely used flat-panel display is an active matrix liquid crystal display with high resolution, hereinafter referred to as liquid crystal display, which can provide high resolution, so it is widely used. However, the inherent limitations of liquid crystal display itself make it unsuitable in some applications. Liquid crystal displays, for example, suffer from a number of manufacturing drawbacks, including slow deposition of amorphous silicon on glass panels and low yields. Moreover, the liquid crystal display requires a high-energy backlight source, b...
