Abstract

The invention discloses a conical ITO-free electrode structure, which comprises a metal electrode X and a metal electrode Y, wherein a discharge part of the metal electrode X and a discharge part of the metal electrode Y are in conical shapes so as to form point discharge. The invention also discloses a method for manufacturing an upper substrate of a plasma display panel with the conical ITO-free electrode structure. The conical ITO free electrode structure is adopted, the discharge part of the metal electrode X and the discharge part of the metal electrode Y are in the conical shapes to form the point discharge, so the ignition voltage is reduced, and simultaneously the covering area is small to increase light transmittance.

Description

Technical field [0001] The invention belongs to the field of gas discharge, and particularly relates to a method for manufacturing a substrate on a cone-shaped plasma display screen without an ITO electrode structure. Background technique [0002] The current general AC gas discharge plasma display screen adopts a surface discharge structure, which includes an upper substrate and a back substrate sealed with it. The upper substrate is equipped with a transparent electrode and a bus electrode. The transparent electrode and the bus electrode constitute the discharge electrode. The discharge electrode includes sustain discharge electrode X and scan discharge electrode Y. The surface of the discharge electrode is covered with a dielectric layer, and the dielectric layer is covered with a magnesium oxide protective layer. The rear substrate is provided with address electrodes perpendicular to the discharge electrodes, and the address electrodes are covered with a dielectric layer. The...
