Organic Light Emitting Diodes

Technology has changed our lives as we dream of. Imagine a simple, low cost, high quality and flexible display. The screen size of a television or computer is a thin plastic piece. Whether you are watching your favorite movies or playing your favorite computer game, you are feeling right with a very bright and vivid color. A heavy and power-consuming cathode ray tube has been called CRT many times. s.

Flexible organic light emitting diode (FOLED); Flexible organic light emitting diode (OLED) is an organic light emitting diode (OLED) incorporating a flexible plastic substrate deposited on a flexible plastic substrate. This allows the device to be bent or rolled up during operation. Currently, research by industry and academic societies focuses on flexible OLEDs to form a way to manufacture rotatable displays. Returning to building materials, nanomaterials began to influence the manufacturing process of nanotechnology steels, nanotechnology steels are stronger, corrosion-resistant, cold-resistant, and plasticity; organic matter, and nanotechnology gypsum dry type It is stronger, lighter, more durable and more water resistant than walls, non-nanosized plaster (Michael F., 2009).

An OLED (organic light emitting diode) is a light emitting diode (LED) where the light emitting electroluminescent layer is a film of an organic compound that emits light in response to a current. The organic semiconductor layer is disposed between the two electrodes. Typically, at least one of the electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens. It is also used for portable systems such as computer monitors and mobile phones, portable game machines, PDAs and the like.

An organic light emitting diode (OLED) which is also an organic electroluminescent device (OELD) is a light emitting diode (LED) whose light emitting electroluminescent layer is made of an organic compound film. A layer of organic semiconductor material is formed between the two electrodes, at least one of which is transparent. This device can be used for small handheld system screens such as television screens, computer monitors, mobile phones and PDAs, clocks, advertisements, information and descriptions. OLEDs can also be used for general spatial illumination sources and large area light emitting devices. Due to the younger developmental stage, OLEDs emit less per unit area than inorganic solid-based LEDs, which are typically designed to be used as point light sources.
