Thin-film transistor architecture for high resolution displays

A semiconductor thin-film transistor, TFT, stack (200) is provided. The stack (200) includes a first TFT structure and a second TFT structure. A same metal layer (232, 233) is configured as both i) a gate metal (232) of one of the first TFT structure and the second TFT structure, and ii) a source-drain metal (232, 233) of the other one of the first TFT structure and the second TFT structure. A display of an active matrix LED type is also provided. The display includes a plurality of pixels and, for each pixel, a pixel driving circuit formed at least partly by the disclosed semiconductor TFT stack.
