>> OLED structure features 7th,August,2018
The base layer, transparent plastic, glass, metal foil, is used to support the entire OLED.
The anode, the anode, is transparent and removes electrons as current flows through the device.
The organic layer is composed of an organic molecule or an organic polymer.
The conductive layer consists of organic plastic molecules that transport "holes" from the anode. Polyaniline can be used as the conductive polymer of the OLED.
The emissive layer consists of organic plastic molecules, ie different from conductive layers, which transport electrons from the cathode; the luminescence process takes place in this layer. Polyfluorene can be used as the emissive layer polymer.
The cathode, which may be transparent or opaque, depends on the type of OLED. When current flows in the device, the cathode injects electrons into the circuit.
OLED is a self-luminous material, which does not require a backlight board. At the same time, the viewing angle is wide, the image quality is uniform, the reaction speed is fast, the color is easy to be colorized, and the simple driving circuit can achieve illumination, simple process, and can be made into a flexible panel. In line with the principle of light and thin, the application range is small and medium size panels.
OLED active illumination, large viewing angle range; fast response, stable image; high brightness, rich color and high resolution. The driving voltage is low, the energy consumption is low, and it can be matched with solar cells, integrated circuits, and the like.
