Embodiment 2

[0022] Such as figure 1 , 4 shown.

[0023] Such as figure 1The three-electrode shadow mask plasma display panel shown includes a front substrate 1, a rear substrate 2, and a shadow mask 3, wherein the shadow mask 3 is packaged between the front and rear substrates 1 and 2, and the front substrate 1 is mainly composed of the front substrate Glass substrate 4, first electrode pairs 5, 6, dielectric layer 7, protective film 8, wherein the first electrode pairs 5, 6 are arranged in parallel on the front substrate glass substrate 4, it can be formed without transparent conductive film ITO electrode, electrode 5 is called sustain electrode, electrode 6 is called scan electrode, dielectric layer 7 is covered on the first electrode pair 5, 6, and protective film 8 is covered on the dielectric layer 7; Substrate glass substrate 9, second electrode 10, dielectric layer 11, wherein the second electrode 10 is located on the rear substrate glass substrate 9, the dielectric layer 11 cov...

Embodiment 3

[0027] Such as figure 1 , 5 shown.

[0028] exist figure 1 In the shown three-electrode shadow mask plasma display panel, the scan electrodes and the sustain electrodes of the front substrate 1 and the address electrodes of the rear substrate 2 are applied as follows Figure 5 As shown in the drive waveform, the shadow mask is applied with a floating potential. During the addressing period, the scan electrodes apply a negative voltage pulse V wy , the addressing electrode applies a positive voltage pulse V a , the sustain electrode is connected to 0V voltage (V wy with V a The sum is greater than the ignition voltage between the scanning electrode and the addressing electrode), the addressing discharge makes the pixels selected in this row enter the ignited state, and after scanning all rows, the addressing of the subfield to the entire screen pixels is completed. Positive wall charges are accumulated on the dielectric layer of the scan electrodes, negative wall charges...

Abstract

The invention discloses a composite display drive method for shadow mask type plasma display panel. The method which combines the advantages of opposite discharge and surface discharge completes opposite discharge between a scanning electrode and an addressing electrode and surface discharge between the scanning electrode and a maintaining electrode at the same time within a maintenance period, thereby realizing composite discharge. The composite discharge enlarges discharge area and shortens the distance between the discharge area and fluorescent powder so as to optimize both luminous efficiency and luminance.

Description

technical field [0001] The invention relates to a driving method of a shadow mask type plasma display panel, in particular to a composite display driving method which combines the advantages of the existing opposing discharge driving method and surface discharge driving method, specifically a shadow mask A composite display driving method for a plasma display panel. Background technique [0002] The structure of the currently used shadow mask type plasma display panel mainly includes a front substrate, a rear substrate and a shadow mask. Starting from the glass substrate, the front substrate is the scanning electrode, the dielectric layer, and the protective layer formed on the surface of the dielectric layer; the rear substrate is starting from the glass substrate, and is the addressing electrode perpendicular to the scanning electrode, the dielectric layer, and the protective layer formed on the dielectric layer. The protective layer; the shadow mask sandwiched between th...
