DIFF Subgroup
H10H 29/30 Active-matrix LED displays
Introduced: January 2025
Full Title
Full titles differ between systems:
IPC:
Integrated devices, or assemblies of multiple devices, comprising at least one light-emitting semiconductor element covered by group > Active-matrix LED displays
CPC:
Integrated devices, or assemblies of multiple devices, comprising at least one light-emitting semiconductor element covered by group H10H20/00 > Active-matrix LED displays
Of 9 combined children, 7 exist in both systems.
2 codes are CPC-only extensions.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 2025.
