Embodiment Construction

[0049] Fig. 3 is a cross-sectional view of the field emission display of the present invention. It is composed of a set of cathode unit and anode unit. The phosphor layer 33 of each anode unit of the anode plate 30 is attached to the anode conductive layer 32, and the anode conductive layer 32 is attached to the anode substrate 31. The electron source emission layer 43 of each cathode unit of the cathode plate 40 is attached on the cathode conductive layer 42, and the cathode conductive layer 42 is attached on the cathode substrate 41. A mesh cover 5 is fixedly installed between the cathode plate 40 and the anode plate 30. The mesh cover 5 has a three-layer structure of a convergence electrode layer 51, an insulating layer 52 and a gate electrode layer 53. The convergent electrode layer 51 faces the anode plate 30 and the gate layer 53 faces the cathode plate 40. Both the gate layer 53 and the convergence electrode layer 51 have an appropriate potential. A plurality of through hol...

Abstract

This invention refers to the guard of quaternary structured field emission display device and making method thereof, a guard is set between anode and cathode board, said guard has a gate and a convergence electrode layer, an insulation layer is set between them to form a independent three-layer structure body, plurality of through holes are set on guard, each hole corresponds each pair of anode and cathode unit, a glass board between guard and anode cathode unit is used as spacer, the convergence electrode layer of guard is opposite the anode board to make the electronic beam emitted from electronic emission source to be limited and reduced the diffusing range, which can make the electronic beam exactly impact the corresponded anode area.

Description

Technical field [0001] The present invention relates to a structure of a field emission display and a manufacturing method thereof, in particular to a fourth pole (ie, convergent pole) added to a well-known three-pole (cathode, anode and gate) structure with a glass plate as a support Quadrupole structure field emission display and its manufacturing method. Background technique [0002] In recent years, flat panel displays (Flat Panel Display, FPD) have become extremely popular in the market, and various types of flat panel displays continue to appear in the market, including field emission displays (FED), liquid crystal displays (LCD), plasma displays ( PDP), Organic Light Emitting Diode Display (OLED), etc. Lightness and thinness are the common characteristics of these flat-panel displays, and according to the different characteristics of various flat-panel displays (such as size and brightness, etc.), some are suitable for small-sized panels, such as mobile phones and personal...
