A method of compensating an OLED (organic light emitting diode) display device (100) for burn-in of pixels of the OLED display involves; measuring a first voltage drop across at least one test pixel of the display and measuring a second voltage drop across at least one other pixel of the display. From the first and second voltages and from a value (V1), representing a drive voltage increase for a loss in efficiency of said display due to burn-in, an estimated reduction in efficiency of the display due to burn-in is determined. A driver for the display is then compensated using the estimated efficiency reduction, preferably by increasing the drive current by a factor dependent on an inverse of the estimated efficiency reduction. The test pixel may be chosen from the 20% of pixels having the least aging and preferably is the least aged pixel of the display. |
