Abstract (en)
An image display device comprising means for emitting a row of electron beams and an electron optics for the row of electron beams, including an assembly of at least two electrodes, provided with contact planes, which are separated by insulating interfaces which are contiguous to the contact planes. Such an assembly is simple to manufacture, is mechanically stable and has an appropriate microphonic behaviour, i.e. it is less sensitive to microphonics.
