Flat configuration image display apparatus.

摘要

In a flat configuration color display CRT in which one or more rows of electron beams (11) are generated with the electron beams passing through respective apertures in successively disposed electrodes including horizontal deflection electrodes (7a,7b), apertures (18) formed in an electrode (6) positioned adjacent to the horizontal deflection electrodes have a central axis position displacement with respect to corresponding apertures (20) of the horizontal deflection electrodes. A trajectory correction voltage which varies during each vertical scanning interval is applied to that adjacent electrode to execute dynamic adjustment of electron beam landing positions and thereby correct for an angular positioning error between a fluorescent layer pattern (10a) of the CRT and the electrode structure.
