Organic Light Emitting Diode displays attain higher performance when addressed by an active matrix. However, in conventional designs the OLEDs has to emit through the substrate and the active matrix which must be fabricated before the OLED is deposited. Because OLEDs require a high current density, the addressing elements take up the majority of the space in the pixel, resulting in a low aperture ratio. We have developed fabrication processes for top- emitting OLEDs that solves the problem and provide more flexibility in the design of the matrix. The top transparent electrode is ITO sputtered at room-temperature and low power to minimize damage on the underlying organic layers.
