ABSTRACT:
There is disclosed a method of permanently attaching metallic spacers in gaseous discharge display panels by ultrasonically bonding said spacers between the glass substrates thereof to thin film metal tabs located between the electrodes. Such a method prevents any subsequent movement of the spacers after attachment and makes the spacers substantially invisible to the naked eye. The article so bonded is also an integral part of this invention.
