Abstract
A multi-channel voltage sensing circuit for pixel compensation includes a plurality of channel circuits arranged for multiple channels; and a first dummy channel circuit and a second dummy channel circuit disposed among the plurality of channel circuits with some channel circuits interposed therebetween, wherein the first dummy channel circuit and the second dummy channel circuit receive a first reference voltage of a fixed level, and provide electrical coupling to adjacent channel circuits.
