·Small green circles are manganese atoms.
·Large blue circles are excited manganese atoms.
·The horizontal dashes represent mobile electrons in the phosphor particle.
·Electrons in the phosphor particles are driven by the
electric field. These electrons slam into manganese atoms in the
phosphor and excite
them.
·The excited manganese atoms relax by emitting a visible
photon.
·The motion of the electrons is proportional to the
electric field.
·The electric field is proportional to the applied
voltage and inversely proportional
to the electrode separation. Thus the
brightness will increase by
raising the voltage or thinning the phosphor and the dielectric
layers.
