ST patent application US20120286135 "Low drop-out regulator with distributed output network" by Jingfeng Gong, Yann Desprez-Le-Goarant (Singapore), proposed a regulator for a pixel array with distributed output transistor that "improves localized heat dissipation by spatially-distributing transistors, and reduces IR drop across an output track by providing a consistent output voltage at each output node located along the output track." (I'd say with improved consistency, not exactly the same voltages).
The prior art is shown on Fig. 1A:
The proposed solution is shown on Fig. 2:
