H01J 11/10

AC-PDPs with at least one main electrode being out of contact with the plasma

Introduced: January 2012

Full Title

Full titles differ between systems:

IPC:

Gas-filled discharge tubes with alternating current induction of the discharge, e.g. alternating current plasma display panels [AC-PDP]; Gas-filled discharge tubes without any main electrode inside the vessel; Gas-filled discharge tubes with at least one main electrode outside the vessel > AC-PDPs with at least one main electrode being out of contact with the plasma

CPC:

Gas-filled discharge tubes with alternating current induction of the discharge, e.g. alternating current plasma display panels [AC-PDP] (circuits or methods for driving PDPs G09G3/28); Gas-filled discharge tubes without any main electrode inside the vessel; Gas-filled discharge tubes with at least one main electrode outside the vessel > AC-PDPs with at least one main electrode being out of contact with the plasma

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

IPC defines codes here since 2012.
