Apply positive voltage pulse at the address period addressing electrode, scan electrode and keep electrode and apply negative voltage pulse, wherein the voltage amplitude of scan electrode is with the voltage amplitude of keeping electrode or for identical, or is difference.
Each cycle of keeping is made up of three phases in the phase of keeping, and the phase one scan electrode applies positive voltage pulse, keeps electrode and addressing electrode and keeps ground state, mainly carries out the subtend discharge between scan electrode and the addressing electrode; Subordinate phase is kept electrode and is applied positive voltage pulse, and scan electrode and addressing electrode keep ground state, mainly carries out scan electrode and keeps surface-discharge between the electrode; Phase III keeps electrode and scan electrode applies negative voltage pulse, and addressing electrode keeps ground state, mainly keeps the subtend discharge between electrode and the addressing electrode, wherein keeps the voltage amplitude of electrode and scan electrode or for identical, or be difference.
Each keeps the voltage pulse width of voltage pulse width, subordinate phase of the phase one in cycle and the voltage pulse width of phase III or for identical, or be difference.
Beneficial effect of the present invention:
Because the image display driver waveform of existing shadow mask plasma display panel only adopts the form of subtend discharge or surface-discharge in the phase of keeping, and causes brightness and efficient can not reach optimization.According to the characteristics of subtend discharge and surface-discharge, the present invention proposes to adopt shadow mask circulation discharge drive waveforms, makes brightness and efficient obtain optimization.The experimental result of subtend discharge, surface-discharge and circulation discharge shows, the strength of discharge of circulation discharge is higher, discharging efficiency is between surface-discharge and subtend discharge, adopt the circulation discharge to make region of discharge enlarge, diminish with the distance of fluorescent powder, thereby luminescence efficiency and brightness all are optimized.
