Colour mixing


The main components of a plasma screen are the electrodes and the pixels located between them. Each pixel consists of three sub-pixels or cells, which can emit red, green or blue light when charged by electric current. The colour of the pixel at a particular moment is created by a mixture of the colours of the cells.

The electrodes supply the electric current necessary for the sub-pixels, each of them being supplied by a separate electrode, which means they are individually controlled.

The cells are filled with a mixture of noble gases, which become ionised when charged by electric current and enter a plasma state while emitting ultraviolet photons which are invisible to the human eye. The UV photons are represented as purple spheres in this animation.
The UV photons then strike the layer of phosphors painted on the inside of the cell. When this happens, the layer of phosphors emits visible light in red, green or blue, depending on the type of fluorescent material.
