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.
Claims22
A current detection device, comprising a plurality of detection circuitries each coupled to a sense line in a display panel, wherein the detection circuitries comprise a current detection circuitry configured to detect a current on the sense line coupled to the current detection circuitry.
