1. An electronic device, comprising:
a pixel array structure, comprising a plurality of signal lines;
a redistribution structure, overlapping the pixel array structure, comprising a plurality of conductive lines; and
a plurality of conductive via structures, electrically connecting the signal lines of the pixel array structure and the conductive lines of the redistribution structure, wherein at least one of the conductive via structures comprises a middle pattern, a top pattern and a conductive via connected between the middle pattern and the top pattern, and wherein:
the middle pattern shares a first conductive layer with the pixel array structure;
the top pattern and the conductive via share a second conductive layer with the pixel array structure; and
the middle pattern has a different shape than the conductive via,
wherein the plurality of signal lines comprises a plurality of power lines and a plurality of data lines, the plurality of power lines and the plurality of data lines are electrically connected to different conductive via structures, the pixel array structure further comprises a plurality of sub-pixels, two adjacent rows of the sub-pixels share one power line electrically connected to at least one of the conductive via structures, and
wherein the plurality of signal lines further comprises a plurality of scan lines, which intersect with the plurality of power lines and the plurality of data lines.
