Abstract
Evacuation of the volume of a field emission display can be carried out more easily by attaching the auxiliary chamber of various shape to the main space of a field emission display, which enlarge the volume of the field emission display. Several types of auxiliary chambers are attached to the main space of a field emission display and the resultant structures are described. The main purpose of the present invention is to introduce the method of providing the space for placing getters and increasing the conductance of the system to evacuate by enlarging the total volume of the field emission display.
Claims14
A field emission display comprising:
- a face plate where a phosphor layer and a transparent electrode are formed in a pixel;
- a base plate comprising emitters, cathode electrodes and gate electrodes;
- an auxiliary base plate with an auxiliary side wall, supporting grooves formed in an outer direction of circumferences of openings of said auxiliary side wall, auxiliary spacer supporting said base plate, and lead lines for an electrode which are formed on spacers formed for maintaining a constant space between said face plate and said base plate;
- and
- a side wall formed for sealing between said face plate and said auxiliary base plate.
A field emission display comprising:
- a face plate on one side of which an anode electrode and a phosphor layer are formed in sequence;
- a base plate which is placed oppositely to said face plate and on one side of which cathode electrodes and emitters are formed;
- spacers which form panels between said face plate and said base plate;
- a first opening for exhaustion which is vertically formed in one portion of said base plate where said cathode electrodes are not formed;
- outgoing lines for electrode which are formed on said base plate;
- a lead line for connecting said base plate to said outgoing lines for electrode;
- and
- an auxiliary chamber containing an opening for exhaustion having a hemispherical inner space connected to said base plate.
