H10H 29/30 Active-matrix LED displays
Introduced: January 2025
Full Title
Full titles differ between systems:
Integrated devices, or assemblies of multiple devices, comprising at least one light-emitting semiconductor element covered by group > Active-matrix LED displays
Integrated devices, or assemblies of multiple devices, comprising at least one light-emitting semiconductor element covered by group H10H20/00 > Active-matrix LED displays
Additional Content IPC
pixel pixels unit of a display device, the unit often having an arrangement of subpixels, e.g. an RGB pixel comprising red (R), blue (B) and green (G) subpixels, and the unit typically repeating across the display. subpixel subpixels portion of a pixel capable of emitting light of a particular colour, typically red (R), blue (B) or green (G), and separately addressable from the other subpixels of the pixel. The subpixel includes one or more light-emitting elements, each being connected to addressing circuitry, e.g. a driving transistor.
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.
