ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION (arrangements for transferring data between digital computers and displays G06F3/14; static indicating arrangements comprising an association of a number of separate sources or light control cells G09F9/00; static indicating arrangements comprising integral associations of a number of light sources H01J, H01K, H10H, H05B33/12; scanning, transmission or reproduction of documents or the like, e.g. facsimile transmission, details thereof H04N1/00)

Introduced: January 1980

Description

G09G encompasses electrical and electronic circuits and systems for controlling display devices that use static visual elements to present changing information. This includes control architectures for technologies such as cathode-ray tubes (CRTs), liquid crystal displays (LCDs), light-emitting diodes (LEDs), plasma displays, and other electro-optical devices. The classification covers driver circuits, timing generators, memory interfaces, signal processing, and refresh mechanisms necessary to modulate static display components into dynamic visual output. Related display-specific subcategories address particular technologies (e.g., G09G 3 for CRTs, G09G 5 for specific display types), while G09G itself focuses on the broader control infrastructure and general circuit principles applicable across display modalities.

CPC subdivides this area 6x more granularly than IPC with 15 additional codes.

15 codes are CPC-only extensions.

Note: 15 CPC extensions are marked as secondary classification only.

2 shared codes have differing titles between IPC and CPC.
