Panasonic say that they’re the first TV manufacturer to remove all lead from the production of their current plasma display panels, including their 103-inch monster. The process started in Spring 2006 with their new plasma TV line in Europe and the US.
Traditionally, lead oxide glass is used in the dielectric layer, electrodes, seal and other parts of the structure. However, Panasonic have developed a new material similar in properties to the lead oxide glass, plus the optimisation of heating conditions.
It’s all a bit technical, but the bottom line is that all Panny TV’s are now free from lead, which should hopefully be a little kinder on the environment.
