Flexible Organic light emitting diodes are the electronic devices. These devices are made by placing a thin film of two different types of an electroluminescent organic material between two conductors of different work functions using flexible substrates. When an electrical voltage is applied, electrons and holes are injected into the electroluminescent material. When these electrons and holes recombine, energy is emitted in the form of light. One or more additional thin layers are generally added for different purposes such as electron and hole transport in device. OLEDs can be used for different purposes like large and small area flat panel flexible self-luminous displays in many consumer products. The performance achieved was 10,000 hours of lifetime at initial luminance of 1000cd/m2. Some of the advantages of OLED technology work and focus on the easiness of chemically modifying the materials, either to tune the colors or to make them processable, through the control of solubility. This seminar paper presents a new application for large-area, high-resolution, flexible organic light-emitting diode (FOLED) display technology currently used to manufacture low-cost color flexible displays on thin metal foil or on plastic substrates.
