Abstract
A flat-panel cathode-ray tube display contains electron-emissive regions () spaced non-uniformly apart from one another in a line of the electron-emissive regions so as to better utilize the space where the electron-emissive regions are located. Alternatively or additionally, electron focusing can be appropriately made more concentrated by implementing each electron-emissive region as two or more portionsA-F) situated suitably with respect to openings (A-F) in an electron-focusing system ().
