Abstract
During the construction of display gas panels front and back panels are connected together by means of a seal which forms a chamber for receiving a display gas. A hole is provided in the back plate which is outside the display viewing area and a glass tube is fitted into this hole and sealed to the assembly. The tube is used to first evacuate and then admit display gas into the chamber. An electric tip-off oven is used to collapse the tube stem to form a permanent seal. A cast protective heat sink and a reflective foil wafer are used to protect the gas panel and the tube-to-gas panel interface from damage by the oven.
