Abstract:
A display device may include rows of pixels that may display image data on a display and a circuit. The circuit may perform a progressive scan across the rows of pixels to display the image data using a plurality of pixels, supply test data to a pixel of plurality of pixels that corresponds to a first row of the rows of pixels during one frame of the progressive scan, and initiate a sensing period for determining one or more sensitivity properties associated with the pixel based on the performance of the pixel with respect to the test data in response to receiving a pulse of a first global signal. The circuit may then end the sensing period in response to receiving a second global signal and resume the progressive scan across the rows of pixels to display the image data after the sensing period ends.
