ITO-less OLED tiles open up opportunity for lower prices
Commercially available OLED lighting tiles currently utilize indium tin oxide (ITO) transparent electrodes. However, due to the limited conductivity of ITO (20 ohms/sq on glass and 50-100 ohms/sq on flexible plastic film), the voltage drops considerably over lengths larger than 2 centimeters, requiring the application of metal grids on top of the ITO to prevent any gradients in light emission caused by the voltage drop. Cambrios ClearOhm coatings can have a resistance as low as 5 ohms/sq with greater than 90 percent transmission independent on the carrier substrate, enabling large 100 cm2 tiles with uniform light emission. In addition the ClearOhmT electrodes offer significant potential for cost reductions in comparison to ITO and are suited for all sorts of flexible device applications.
Cambrios has already demonstrated a 5 cm by 5 cm OLED lighting tile with efficiencies greater than 40 lm/W, based on ClearOhm electrodes. OLEDs made using Cambrios ClearOhm electrodes exhibit improved angle dependence of color, providing higher quality OLED displays and lighting products. The ClearOhm-based 10 cm by 10cm tile proves ClearOhm transparent coating material can create high performance OLED Lighting panels at commercially viable sizes.
Cambrios ClearOhm coating material creates highly conductive and transparent electrodes that enable large area OLED lighting tiles. The coating material can form transparent conducting layers on a variety of substrates and at a wide range of sheet resistances to enable an array of applications including touch screens, liquid crystal displays, OLED devices, and thin film photovoltaics.
