FLAT PANEL DISPLAY UTILIZING LINEAR ARRAY OF FIELD EMISSION CATHODES

摘要

A flat panel display (11), having at one edge a linear array of electron guns (16) incorporating field emission cathodes (17, 18, 19). Each of the field emission electron guns is individually addressable, and all are simultaneously addressable. A deflecting structure (28) is provided to deflect electron beams issuing simultaneously from the guns toward a phosphor-coated display screen (12) to simultaneously address an entire column of pixels on the screen. All columns of a raster scan are sequentially addressed to thereby form the full raster scan. A beam alignment/calibration structure is included to enable correction of any deviation of a beam from a desired intensity or alignment.
