Control method applying voltage on plasma display device and plasma display panel

摘要

The present invention provides a control method for applying a voltage on a plasma display panel of a plasma display device that realizes an improvement in a ultraviolet emission efficiency. The invention provides a plasma display device comprising a plasma display panel 101 having a plurality of discharge cells each having a pair of sustain discharge electrodes 102 and 103 and an address electrode 104 wherein a voltage is applied to at least one of the sustain discharge electrodes and the address electrode in a sustain discharge period. The plasma display device comprises applying repeatedly to the sustain discharge electrodes 102 and 103 a sustain discharge voltage of a voltage waveform having a rise period (Tr) from a first voltage level to a second voltage level, a sustain period (Tsus) for maintaining the second voltage level, a fall period (Tf) from the second voltage level to the first voltage level and a sustain period (Tg) for maintaining the first voltage level, and, in a voltage for applying a constant voltage Va (V) to the address electrode A, applying to the sustain discharge electrodes 102 and 103 a composite voltage which is a sum of the sustain discharge voltage and a variation voltage from a circuit for generating variation waveform in high frequency with setting the head of the sustain discharge voltage of the rectangular waveform to 0s and during a time 0<T<Tr (s).
