Problems solved by technology

[0006] However, during the operation of an electron emission display, it is difficult to emit electron beams in a completely straight manner
In other words, while most of the electrons emitted from the electron emission region of the first substrate are diffused or attracted to the phosphor layer of the second substrate, some electrons are diffused or scattered at a predetermined diffusion angle

Embodiment Construction

[0020] Various aspects of the invention are described in detail below, as well as examples in the accompanying drawings, wherein like reference numerals refer to like elements throughout. Various aspects are described below so as to explain the present invention by referring to the figures.

[0021] 1 and 2 are a partially exploded perspective view and a partial sectional view, respectively, of an electron emission display according to an aspect of the present invention. Although not required in all configurations, an FEA type electron emission display is shown in FIGS. 1 and 2 .

[0022] As shown in FIGS. 1 and 2 , the electron emission display 1 includes a first substrate 10 and a second substrate 12 which are parallel to each other and face each other with a predetermined distance therebetween. A seal (not shown) is provided on the periphery of the first substrate 10 and the second substrate 12 to seal them to each other. After sealing, the sealed space is evacuated to ab...

Abstract

An electron emission display includes first and second substrates facing each other, electron emission regions to emit electrons and formed on the first substrate, and driving electrodes formed on the first substrate to use in the control of the emission of electrons from the electron emission regions. Phosphor layers are formed on a surface of the second substrate. An anode electrode is placed on a surface of the phosphor layers. Spacers are mounted between the first and the second substrates. Antistatic electrodes are placed over the first substrate such that the antistatic electrodes are insulated from the driving electrodes, and electrically connected to the spacers.

Description

technical field [0001] The present invention relates to electron emission displays. In particular, the present invention relates to an electron emission display having a spacer installed in a vacuum container to resist pressure applied thereto. Background technique [0002] In general, electron emission elements are classified into different types according to the type of electron source. These include the first type using hot cathodes and the second type using cold cathodes. A second type of electron emission element using a cold cathode includes a field emitter array (FEA) type, a surface conduction emission (SCE) type, a metal-insulator-metal (MIM) type, and a metal-insulator-semiconductor (MIS) type. To construct an electron emission display, an array of electron emission elements is arranged on a first substrate, together forming an electron emission device. The electron emission device is combined with a second substrate having a light emission unit having a fluores...
