Method and OLED.
Background technology
Organic electroluminescence device（Organic Light-Emitting Diodes, abbreviation OLED）It is self-luminous device
Part, it has light weight, ultra-thin, and theoretical luminous efficiency is high, and more important point can be to make flexibility, and either illumination is still aobvious
Show field, it will be following developing direction.
The efficiency of luminous organic material and life-span are obtained for very big raising, especially recent years, HONGGUANG and green glow
The photoelectric properties of luminous organic material have been fully achieved the requirement of industrialization, but the efficiency of blue light material is still very low, the longevity
Life is also very low, and especially in the case where high voltage and long-time light device, life-span and efficiency decay are more accelerated.Current is aobvious
Show and illuminating product be driven by unidirectional current, and the quality of product quality be will be by long-time using verifying
's.When the overlong time for using, the efficiency of luminescence unit and life-span can quickly reduce, while its CIE is likely to occur
Very big change.Especially for blue light emitting unit, its life-span and efficiency are inherently very low, for a long time by unidirectional current flow point
Bright, its photoelectric properties attenuation ratio is red and green emitting unit will be fast.But whether being led in lighting field or showing
Domain, blue light is requisite, is difficult to show white light without blue light, so blue light efficiency is low and the life-span differs from this difficult problem needs
Overcome.
