 improve the technology of the luminescent material color purity and luminous efficiency, while etching the metal mask is also crucial.

Currently, small organic molecules AlQ3 luminescent material is a good point a small green LED on the material, its green color purity, luminous efficiency and stability are good. But a red light emitting OLED best luminous efficiency of small molecule materials only 31m / W, 10,000 hours life, blue light-emitting small molecule materials development is very slow and very difficult. Small organic molecules emitting material biggest bottleneck is the purity of the red and blue materials, efficiency and longevity. But it is to the subject by the light emitting dopant material, has got a color purity, luminous efficiency and good stability are blue and red. T8 Tube

The advantage of polymer light-emitting materials can be chemically modified by adjusting the light wavelength, has got its name from blue to green to red visible range covering the entire range of colors, but the life of only a few tenth of a luminescent material molecules, Therefore, the polymer light-emitting materials, luminous efficiency and lifetime are to be improved. Continue to develop light-emitting material with excellent performance materials development workers should be an arduous and long-term issues. LED Flexi
