Abstract
Described is a CMOS power plane including interleaving contact areas, alternating Vand Vcontact areas, on at least two long sides of the μLED display area. By this way, Vand cathode current are injected uniformly along the four sides of the μLED display panel. A large cathode current distribution ring on Vand Vcircuits is used to distribute the current along the four sides of the panel. The current distribution ring surrounds a pixel die area. An insulated area may be included on the cathode current redistribution ring adjacent one of the of μbumps.
