Abstract
The current sensing device in the present disclosure comprises a plurality of sensing units each of which is connected to a sensing channel. The sensing unit may comprise a reference current generator generating a reference current; a current comparator outputting a comparator output signal based on a pixel current input through the sensing channel and the reference current, and removing an offset deviation component included in the pixel current and the reference current by using a reset current externally applied; and an edge triggered data flip-flop outputting a digital sensing value corresponding to the pixel current based on the comparator output signal.
