Plasma colour matrix display squares having front/rear electrodes and central discharge space with luminophore covered side walls and front face partially covered recycling ultraviolet energy.
Plasma colour matrix display squares having front/rear electrodes and central discharge space with luminophore covered side walls and front face partially covered recycling ultraviolet energy.
The luminophore squares are formed on a front (2) and rear electrode (4) of two matrix networks. There are matrix cells (20) forming a discharge space. The side walls (23) are partially covered with luminphores. The front face (24) is partially covered with luminphores recycling ultra violet energy.
