High-brightness AC plasma display screen

Abstract

A high brightness Ac plasmka display screen contains a front glass plate and a rear glass plate. The front one contains a glass plate, two sets of holding discharging electrodes, dielectric and its protection layers. The rear one contains a glass plate, an addressing electrode, blocking walls, phosphor powder layer and discharging triggers between blocking walls. The two glass plates are sealed together then sealed off after exhaustion, charged with inert mixed discharging gas to form a plasma display screen. The trigger is used during addressing to trigger addressing discharge to reduce the addressing voltage or increase the discharge space height of discharging units and phosphor powder coating areas so as to increase light output and brightness.

Description

[0001] 1. Field [0002] The invention belongs to the field of video manufacturing, and further relates to a plasma display screen, in particular to a high-brightness AC plasma display screen used for displaying information terminals and wall-mounted TVs. 2. Background technology [0003] At present, the general-purpose AC plasma display screens all adopt a surface discharge structure, that is, a transparent discharge electrode is prepared on the front glass plate, a main electrode (metal electrode) is made on the transparent electrode, and then a layer is covered on the electrode. The transparent medium layer is covered with a layer of MgO dielectric protective film on the medium layer. On the rear glass plate, an address electrode, a dielectric layer, a stripe barrier and a phosphor layer are prepared. After the prepared front and rear glass plates are sealed, exhausted, inflated and aged, the AC plasma display screen is made. The display screen is equipped with a correspo...

AI Technical Summary

Problems solved by technology

[0009] The powder coating area is also small, and the brightness of the display screen is low.

[0010] In addition, the address discharge gap Da is the same as the discharge space height of the discharge cell, so the address discharge gap Da and the discharge space height of the discharge cell cannot be individually optimized.
