    Schematic diagram of a plasma1 display panel showing the pixels2 sandwiched between two transparent3 glass panels. Each pixel4 is made up of three gas-filled phosphor-coated cells.

    1. plasma: 1. The fourth state of matter – a gas that is ionised and consists of positive and negative ions (or particles), with no overall charge. It is affected by magnetic fields and has high electrical conductivity. 2. The colourless or pale yellow liquid in blood and lymph.
    2. pixel: The most basic unit of an image displayed on a digital screen or printer. Smaller pixels (higher resolution) provide a sharper image. The term pixel is short for picture element.
    3. transparent: A substance that light can pass through without scattering. Objects are clearly visible when viewed through a transparent substance such as smooth window glass or water.
    4. pixel: A contraction of ‘picture element’. In a medium-sized plasma display flat-screen TV, there are over 900 000 tiny cells called pixels. Each pixel is made up of three gas-filled cells that emit either red, blue or green light when electrically stimulated.

    We happily live in the Earth’s gaseous lower atmosphere composed of a mixture of gases – primarily nitrogen and oxygen. However, if we move upwards from the Earth’s surface, the environment ...
