Identification marks of picture tube parts |
摘要 |
It is known to provide picture tube parts with identification marks. According to the state of the art, this identification of picture tube parts is achieved by attaching special layers or labels containing the identification data to the outside of the glass pans (10). However, this technique is extraordinarily costly because of the additional layers or labels. The invention shows that the respective identification marks (16) are formed directly on a first functional layer applied to the inside (19) of the respective picture tube part. The process is very simple if the respective identification marks (16) are burned into the first functional layer by means of a laser.
