using AC panels

Introduced: January 2000

Full Title

Control arrangements or circuits, of interest only in connection with visual indicators other than cathode-ray tubes > for presentation of an assembly of a number of characters, e.g. a page, by composing the assembly by combination of individual elements arranged in a matrix > using controlled light sources > using luminous gas-discharge panels, e.g. plasma panels > using AC panels

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 1990.
