Figure 7From: Thermal behavior and indirect life test of large-area OLED lighting panelsVoltage vs. temperature at J low = 0.1 mA/cm2for a large area OLED light panel with an equivalent architecture to the OLED test pixel. The gradient gives 1/K, where K = ΔT j ΔV . For this panel operating at 0.1 mA/cm2, K = 167°C/V. The dotted line shows an extrapolation to 20°C.Back to article page
