Abstract:
Disclosed in the embodiments of the present disclosure are a current detection device and a display device. The current detection device includes: a plurality of detection circuits; the detection circuit includes: a feedback compensation circuit and a current detection circuit; and the feedback compensation circuit is configured to generate a noise inversion signal by inverting a noise AC signal generated on the predetermined power line in the display panel and to provide the noise inversion signal to a first end of the current detection circuit; and the current detection circuit is configured to output a detection signal to the signal output end according to the noise inversion signal, the signal on the detection line and the signal of the reference voltage end.
