Abstract: A control method and a control device for a current detection apparatus are provided, which are used to improve the accuracy of current detected by the current detection apparatus. A sensing control switch is controlled to be in an on state at a first time point before an integration operation is performed on the detection line; a current detection circuit is controlled to start the integration operation on a current of a detection line at the integration start time point to obtain an integrated voltage signal corresponding to the detection line; multiple samplings are performed on the integrated voltage signal, and an output voltage difference between different sampling points is determined; and the current of the detection line is determined based on the output voltage difference.
