The present disclosure discloses a sampling method, a sampling control method, a sampling device, a sampling control device, a sampling control system, and a display device. The present disclosure provides a sampling method for sampling pixel units disposed on a display substrate, the method including: the controller controlling a plurality of sampling modules to be simultaneously turned on, so that a plurality of sampling modules controlled by the controller are capable of receiving luminance information of the pixel units obtained through sampling of the sampling channel; the controller sequentially controlling a group of sampling channels to be simultaneously turned on, so that the group of sampling channels simultaneously sample the luminance information, and transmit the sampled luminance information to respective sampling modules connected to the group of sampling channels through the output terminals of the group of sampling channels.
