Layers for protecting or enhancing the electron emission, e.g. MgO layers

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 > Constructional details > Vessels, containers or parts thereof, e.g. substrates > Layers for protecting or enhancing the electron emission, e.g. MgO layers

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 > Constructional details > Vessels, containers or parts thereof, e.g. substrates > Layers for protecting or enhancing the electron emission, e.g. MgO layers

No child classifications to compare. This is a leaf node in both IPC and CPC.
