FIELD EMISSION DISPLAY FOR MAXIMIZING GAS ABSORPTION ABILITY TO CONTINUOUSLY MAINTAIN HIGH-DEGREE VACUUM STATE INSIDE PANEL

摘要

PURPOSE: A field emission display is provided to place a getter ring containing a getter material inside a panel and activate the getter material after tip-off to form a getter layer in a wide area at the side of a frame, thereby maximizing gas absorption ability to continuously maintain high-degree vacuum state inside the panel. CONSTITUTION: A field emission display includes an upper substrate(110) having a fluorescent layer(112) and an anode electrode layer for applying voltage to the fluorescent layer, a lower substrate(120) on which a field emission emitter(124) is formed, and a frame(108) for maintaining a predetermined distance between the upper and lower substrates. A shadow mask(131) having electron beam passage holes is located at the side of the fluorescent layer. The shadow mask is welded to a rail(123) mounted on the upper substrate. A getter ring(105) filled with a getter material(103) is fixed to the side of the rail using an antenna.
