摘要：
The invention relates to a vacuum display device comprising a display screen (30) having picture elements (35), cathode means (20) for generating a plurality of electron beams (EB), each corresponding to one of the picture elements (35), and addressing means (41,42) for addressing the picture element (35) through modulation of the intensity of an electron beam corresponding to the picture element (35). A channel structure (10) is arranged adjacent the cathode means (20). The channel structure (10) comprises a plurality of electron beam guidance cavities (15), each corresponding to one of the picture elements (35), and protects the cathode means (20) from incident ions. The exit (17) of the cavity (15) is smaller than the entrance (16), so that an electron beam (EB) exiting from the cavity (15) has a particularly high brightness and spatial uniformity.
