ABSTRACT:
The present invention relates to a display device comprising a cathode ray index tube (1) having a neck portion (1″) and a screen portion (1). The display device comprises an electron gun assembly (3) for generating a plurality of electron beams (3R,3G,3B), positioned in the neck portion (1″) of the cathode ray index tube (1), a deflection unit (5), placed around the neck portion (1″) of the cathode ray index tube (1), for deflecting said plurality of electron beams (3R,3G,3B), and a convergence unit (6) for converging said plurality of electron beams (3R,3G,3B). The deflection unit (5) is placed at an axial distance from said electron gun assembly (3), closer to said screen portion (1′). The convergence unit (6) is placed in close proximity to the deflection unit (5).
