Abstract

A current detection device for detecting a current on the sense line, and compensating for a grayscale of a pixel in accordance with a difference in the detected currents, so as to provide the pixels with uniform brightness. An integration operation is performed on a sense line through an integration sub-circuitry to obtain an output voltage, and the current on the sense line is determined in accordance with the output voltage.
