Some specific embodiment parties of the organic electroluminescence device provided to the first aspect of the present invention below in conjunction with the accompanying drawings
Formula illustrates.
Referring to Fig. 1, the organic electroluminescence device that one embodiment of the invention provides has blueness, red and green sub- picture
Plain region, organic electroluminescence device include through-thickness and are successively set on chromatic filter layer on underlay substrate 1, semi-transparent half
Anti- layer 5, transparent electrode layer 6, organic luminous layer and metal electrode layer 12, wherein：
Chromatic filter layer water white transparency in the subpixel area of blueness, chromatic filter layer include the sub- picture for being arranged on red
Red color membrane structure 2 in plain region, the green color membrane structure 3 being arranged in the subpixel area of green and for compensating
The transparent planar layer 4 of segment difference between red color membrane structure 2 and the color membrane structure 3 of green；
Transflective layer 5 is the metallic film that thickness is 5~20nm, be arranged on blueness subpixel area in, and with gold
The micro-cavity structure of outgoing blue light is formed between category electrode layer 12；
Organic luminous layer includes the first organic function layer 7, red strip-shaped light-emitting structure 8, the strip-shaped light-emitting structure of green
9th, 10 and second organic function layer 11 of blue light-emitting layer；Wherein, the first organic function layer 7 is arranged on strip-shaped light-emitting structure and transparent
Between electrode layer 6, the strip-shaped light-emitting structure 9 of red strip-shaped light-emitting structure 8 and green is set with layer, and blue light-emitting layer 10 is by whole
Face is formed, and the second organic function layer 11 is arranged between metal electrode layer 12 and blue light-emitting layer 10.
It will be appreciated that above-mentioned red strip-shaped light-emitting structure 8 refers to sending the string light knot of the light of red
Structure, above-mentioned green strip-shaped light-emitting structure 9 refer to sending the strip-shaped light-emitting structure of the light of green, above-mentioned blue light-emitting layer
10 refer to sending the ray structure of the light of blueness.
The operation principle of organic electroluminescence device provided in this embodiment is illustrated below：
After applying operating voltage between metal electrode layer 12 and transparent electrode layer 6, the blue-light-emitting in organic luminous layer
Layer 10 sends blue light, and red strip-shaped light-emitting structure 8 sends feux rouges, and green strip-shaped light-emitting structure 9 sends green light, and what is sent is red
Light and green light are transmitted by the color membrane structure of transparent electrode layer 6, transparent planar layer 4 and corresponding color, corresponding color
Color membrane structure the light of corresponding color is filtered, to improve the excitation purity of the light of corresponding color.When blue light-emitting layer 10 is sent out
The blue light gone out by transparent electrode layer 6 reach transflective layer 5, due to transflective layer 5 have the function of it is semi-transparent semi-reflecting, one
Part light is transmitted, and another part light is reflected onto in the micro-cavity structure formed between transflective layer 5 and metal electrode layer 12,
Transflective layer 5 is reflexed to by metal electrode layer 12 by the part light that transflective layer 5 reflects again, it is seen that some blue light is in microcavity
Vibrated in structure, be so-called microcavity effect.In practical applications, because the chamber of micro-cavity structure grows different, micro-cavity structure
The wavelength for the light that transmissive goes out is different, therefore the micro-cavity structure grown by making default chamber, can obtain the blue light of preset wavelength,
With this come to ensure that blue light has higher excitation purity.Since the blue light of micro-cavity structure outgoing is no longer filtered through color membrane structure
Light, therefore current efficiency can be improved, so as to reduce the power consumption of blue subpixels, extend the service life of blue subpixels.
In above-mentioned operation principle explanation, the luminescence process of organic luminous layer is specially：In metal electrode layer 12 as just
Pole and transparent electrode layer 6 are as in the case of anode, and by hole transport into ray structure, first has the second organic function layer 11
Electric transmission into ray structure, is excited ray structure to shine by machine functional layer 7 when electronics and hole combine in ray structure.

Ray structure 9) and the organic luminous layer that forms of functional layer shine, it is certainly in practical applications, alternative real at some
Apply in example, it not necessary to using the organic luminous layer being made of ray structure and functional layer, other structures can also be used
Organic luminous layer shines, its technical solution can also reach the electricity that blue subpixels are lifted on the basis of high color purity is kept
The basic object of efficiency is flowed, therefore should also be fallen under the scope of the present invention.
In the present embodiment, since transflective layer 5 is the metallic film that thickness is 5~20nm, colored filter under normal circumstances
The thickness of the other structures such as photosphere is micron dimension, and the thickness of transflective layer 5 is nanometer scale, than chromatic filter layer etc. its
His structure is thin very much, therefore contributes to the realization of the semi-transparent semi-reflecting function of metallic film.Certainly in practical applications, can at some
In alternative embodiment, transflective layer 5 need not necessarily use metallic film of the thickness for 5~20nm, in practical applications
The material for making transflective layer can be selected as needed, its thickness can also be configured according to material, as long as system
Making obtained structure has the function of semi-transparent semi-reflecting, and corresponding technical solution should just be fallen under the scope of the present invention.
In the present embodiment, despite with the organic electroluminescence device with blueness, red and green subpixel area
Illustrate, but in some alternative embodiments, organic electroluminescence device need not necessarily have red and green
The subpixel area of color, for the sub- picture with blueness and other at least two random colors (such as yellow, green and purple)
Plain region, corresponding chromatic filter layer include the color membrane structure of other at least two random colors, its technical solution can also reach
To the basic object for the current efficiency that blue subpixels are lifted on the basis of high color purity is kept, therefore it should also fall into the present invention
Protection domain within.
In the present embodiment, due to using the color membrane structure 3 of the red color membrane structure 2 of 4 pairs of transparent planar layer and green it
Between segment difference compensate, therefore facilitate the making of transflective layer 5, transparent electrode layer 6 etc..Certainly in practical applications, exist
In some alternative embodiments, transparent planar layer 4 may not be only the color membrane structure to red color membrane structure 2 and green
Segment difference between 3 compensates, such as is sent out for the organic electroluminescence of the subpixel area with blueness, yellow, green and purple
For optical device, transparent planar layer need to compensate the segment difference between the color membrane structure of yellow, green and purple.In addition,
Also the segment difference between the color membrane structure of 4 pairs of different colours of transparent planar layer need be not necessarily used to compensate, its technical side
Case can also reach the basic object for the current efficiency that blue subpixels are lifted on the basis of high color purity is kept, therefore should also fall
Enter within protection scope of the present invention.
