Abstract
A display device may include a plurality of pixels configured to display image data on a display. The display device may also include a circuit that measures a first current associated with a light-emitting diode (LED) of a pixel of the plurality of pixels in response to the circuit receiving a first data voltage. The circuit may also measure a second current associated with the LED of the pixel of the plurality of pixels in response to the circuit receiving a second data voltage. The circuit may then determine a voltage associated with the LED based at least in part on the first current and the second current.
