Ultra-thin shadow-mask plasma display panel and NB-UVB source

摘要

. The shadow-mask is a special metal mesh which is used to form the discharge cells and embed phosphors. The upper part of the discharge cell has a diamond design and the lower part is slot shaped and the gas channels are made in the back side. The shadow-mask replaces the rib wall while the thin glass sheets are used instead of the conventional dielectric layers. So the structure is simplified as a sandwich which includes the front and rear thin glass sheets, the shadow-mask, MgO layers and the exterior electrodes. Moreover, a special vacuum in-line sealing system, which consists of a vacuum chamber, temperature control system and gas filling system, is applied to the fabrication. The panels can be sealed directly in the system without pumping tubes.
