Abstract

Aiming at the problems of low discharge efficiency and low brightness in the existing surface discharge type shadow mask plasma display panel, the present invention invents a surface discharge discharge device with a finger-joint electrode structure with low ignition voltage, high luminous efficiency and low power consumption. Type shadow mask plasma display panel, which mainly includes front and rear substrates and a conductive shadow mask containing grid hole arrays, a pair of scan electrodes and sustain electrodes on the front substrate and branch electrodes perpendicular to them, and a pair of electrodes on the rear substrate. The addressing electrodes and the grid holes of the conductive shadow mask together constitute the discharge unit, and adopt the working mode of surface discharge. The phosphor is not only coated on the inner wall of the shadow mask mesh, but also coated on the rear substrate where the discharge unit is located. Above all, the inner wall of the shadow mask mesh of the discharge unit and the corresponding powder-coated part of the rear substrate form an area much larger than the area of ​​the phosphor powder of the shadow mask-type opposed discharge unit, and the luminous brightness and luminous efficiency are improved. It has the advantages of low ignition voltage, higher brightness and luminous efficiency, and low power consumption.

Description

technical field [0001] The present invention relates to a flat TV display panel, in particular to a shadow mask plasma display panel, in particular to a surface discharge shadow mask plasma display panel with a finger-joint electrode structure.
