French scientist Georges Destriau discovered electroluminescence (EL) as early as 1936.
The format was first discovered and produced by sandisk in 1994. ... These symptoms include electroluminesense form.
Electroluminescence is the result of radioactive recombination of electrons and holes in a material, usually a semiconductor. The excited electrons release their energy as photons - light. Prior to recombination, electrons and holes may be separated either by doping the material to form a p-n junction (in semiconductor electroluminescent devices such as LEDs), or through excitation by impact of high-energy electrons accelerated by a strong electric field (as with the phosphors in electroluminescent displays).
