Abstract:
A system may include a display panel that includes number of pixels that display image data on a display. The system may also include a circuit that measures a voltage associated with a light-emitting diode (LED) of a pixel of the number of pixels in response to the LED receiving a current. In addition to the circuit, the system may employ data processing circuitry that may generate a calibrated prediction model based at least in part on the voltage and the current, such that the calibrated prediction model predicts a change in voltage performance of the LED as the LED ages.
