Definitions

an anti-reflective coating has the function of reducing its light reflection, therefore increasing its light transmission.
a substrate thus coated therefore sees an increase in its transmitted light / reflected light ratio, which improves the visibility of the objects placed behind it.
a plasma screen comprises a plasma gas trapped between two sheets of glass, and phosphors arranged on the internal face of the back sheet of the screen.
the interactions between the particles of the plasma gas and the phosphors generate a radiation of electromagnetic waves which are located in the near infrared between 800 and 1000 nm and whose propagation, mainly through the face front of the screen, can be the source of very annoying disturbances, in particular for equipment located nearby and controlled by infrared, for example by means of remote controls.
FIG. 2 illustrates a comparative graph of different anti-reflective coatings
FIG. 3 shows two images of a coating respectively, of the film type and of the layer stacking type
