An exoelectron emission which may be emitted from MgO in PDPs contributes to discharge priming. The emission persists for 10 hours or even longer. In order to detect an extremely weak emission, a measuring technique was introduced in which trains of pulses are repetitively applied in order to amplify the number of the electrons. The address discharges of PDPs can reliably be ignited as long as the reset pulses are applied at least once every 10s for 3.5% Xe, or once every second for 30% Xe due to the priming action of the exoelectrons. The reduction of the number of the reset pulses improves the dark room contrast by orders of magnitudes. It can be concluded that MgO in PDPs has three important roles; large secondary electron emission, resistant to ion bombardment, and intense exoelectron emission.
