Proof of switched-back regions by detecting luminance changes in OLEDs: The bottom line of the figure presents the top-view sketches onto an OLED pixel at three different exemplary stages of total applied current. The top-line estimates the luminance profiles across the indicated cross section. While low driving currents result in a homogenous luminance distribution (left column), elevated currents give rise to a gradually decreasing luminance profile (middle column). After exceeding a certain threshold current, the luminance will even reduce ("switch back") in certain areas of the device (right column).
