Abstract (en)
[origin: EP0643412A2] It is known to provide image tube components with identification patterns. According to the prior art, this identification of image tube components is carried out in such a manner that there are applied on the outside of the glass troughs (10) layers or labels which are particular to the cone and contain the identification data. Due to the additional layers or labels, this technique is, however, exceptionally costly, so that the object consisted in simplifying this method. According to the invention, it is specified to form the respective identification pattern (16) directly in a first function layer which is supported on the inside (19) of the respective image tube components. The method can be carried out in a particularly simple manner when the respective identification pattern (16) is burnt into the first function layer with the aid of the laser. <IMAGE>
