Plasma display screen manufacturing method and plasma display screen

Abstract

The invention provides a plasma display screen manufacturing method and a plasma display screen manufactured by employing the manufacturing method. The manufacturing method comprises steps of manufacturing a front substrate, manufacturing a back substrate and subsequent processing steps, the subsequent processing comprises steps that: the front substrate and the back substrate are folded, the first sealing exhaustion is carried out, a work gas is filled, the first characteristic stabilizing operation is further carried out, an exhaust pipe of the plasma display screen is cut, the second sealing exhaustion of the plasma display screen after the first characteristic stabilizing operation is carried out, the work gas is filled, the second characteristic stabilizing operation is carried out, and the plasma display screen is acquired. According to the manufacturing method provided by the invention, twice sealing exhaustions and twice characteristic stabilizing operations are carried out, so impurity gases in an enclosed space of the acquired plasma display screen are effectively eliminated, an integral surface state of the plasma display screen is uniform, and photo-electrical property of the plasma display screen is more stable.

Description

technical field [0001] The invention relates to the technical field of gas discharge, in particular to a manufacturing method of a plasma display screen and a plasma display screen obtained by the method. Background technique [0002] figure 1 It is a perspective view of a partial structure of a plasma display screen 100 in the prior art.
