Stream, other than the application of display, the light-emitting component of Organic Electricity can more form array knot in the material of frivolous deflection
Structure.
In display using upper, full-color is the necessary condition of market success, if distinguishing according to colorization mode, organic electroluminescence
Illuminated display structure can be divided mainly into three-colour light-emitting layer structure, color converting layer (color change media, CCM) and coloured silk
Three kinds of modes such as color optical filtering membrane structure (color filter, CF), wherein three-colour light-emitting layer structure is current organic electroluminescent
The most-often used mode of display true color is that the luminescent material of red, blue, green three colors is respectively coated in picture element, is added not
It is same to be biased to generate full-color effect, and have the advantages that luminous efficiency is optimized.And it is light emitting source that color converting layer, which then utilizes blue light,
Via Color Conversion film blue light is converted into feux rouges or green-blue light respectively and then realizes redgreenblue light.In addition, colored filter
The colored filter that light membrane structure then uses white light source to penetrate similar LCD is full-color to achieve the effect that.
At present on organic electroluminescent LED (OLED) panel because use metal as thin film transistor (TFT) (TFT) and
Electrode, so on panel appearance very strong reflecting effect can be generated because of environment light source, and whole optical characteristics is caused to drop
Low (such as to when coloration).
It is used to improve high reflectance on panel at present and improves the mode of comparison, polaroid is usually sticked on panel
(polarizing film) eliminates the reflection of environment light plus phase shift films (retardation film).Its using it is upper more
It is inconvenient.
