Mercury Quantity in a Fluorescent Lamp for a Backlight of LCD-TVs

The amount of vapor mercury for the generation of glow discharge plasma has been calculated in a fine tube fluorescent lamp having a mixed gas of Ne+Ar including a mercury. When the ionization of atom is considered by the collision between neutral atoms (Ne, Ar, Hg) and electrons of energy , the density of vapor mercury atom has been obtained as for the plasma density . In the fluorescent lamps of out diameter 4 mm used for -inch LCD-TVs having a mixture gas of Ne(95%)+Ar(5%) with the pressure of 50 Torr, the quantity of vapor mercury for the glow discharge has been caculated as .
