===Technology Mapping===
 * An interesting trend in top emission In OLED's devices not all internally generated light is the use coupled out of principle of internal reflection the device (only 20%-50%), which reduces the device efficiency and lifetime. Interesting trend in structures applied to improve outcouple efficiency in order to enhance the display efficiency and Lifetime of the OLEDtop emission OLEDs are depicted.
