Embodiment
At first, see also Fig. 3 and shown in Figure 4, be respectively the generalized section and the section construction generalized section of a preferred embodiment of the present invention.As shown in the figure, Organic Light-Emitting Device 400 of the present invention mainly is provided with at least one organic EL component 40 in a colored filter 30, and filters the light source (S1, S2, S3) that organic EL component 40 is produced with colored filter 30.Wherein, colored filter 30 mainly is respectively arranged with at least one black matrix" 33 and at least one chromatic photoresist 35 on a transparency carrier 31, and is coated with a planarization layer 37 on black matrix" 33 and/or chromatic photoresist 35.
Supplying with between first electrode 41 and second electrode 45 has a current signal, will cause organic luminous layer 43 to produce a white light source W.There is the white light source W of part directly to penetrate hole transport implanted layer 431, and derives organic EL component 40, path r1 as shown in Figure 3.Then penetrating electrons transmission implanted layer 433 of white light source W is partly arranged, and via after 45 reflections of second electrode, penetrating electrons is transmitted implanted layer 433, organic luminous layer 43 and hole transport implanted layer 431 in regular turn again, and derives organic EL component 40, path r2 as shown in Figure 3.
The present invention mainly adjusts the optical path difference of hole transport implanted layer 431 and/or electric transmission implanted layer 433, to improve the light source derivation rate of particular range of wavelengths among the white light source W.For example, when the optical path difference of hole transmission layer implanted layer 431 is the integral multiple of 650nm to 760nm, for derive the white light source W of organic EL component 40 via path r1, the light source of its Wavelength distribution between 650nm to 760nm will have higher derivation efficient, and make that deriving light source is one first light source S1.
Again, there is the white light source W of part to derive by path r2, can make that wherein the optical path difference of electric transmission implanted layer 433 is 1/2nd times of 650nm to 760nm, help improving among the white light source W equally, the light source of Wavelength distribution between 650nm to 760nm derived efficient, and this derivation light source is similarly the first light source S1.
The first light source S1 is compared to the light source S (as illustrated in prior art fig. 1) of prior art, and the distribution of its wavelength is different.For example, the first light source S1 compares with the light source S of prior art, and the ratio of its Wavelength distribution between 650nm to 760nm is higher.
If first chromatic photoresist 351 is a red photoresistance (only allowing the chromatic photoresist that wave-length coverage is passed through between the light source of 650nm to 760nm), and filter the first light source S1 with first chromatic photoresist 351.Compared to the light source S of prior art, the first light source S1 has preferable penetrance to first chromatic photoresist 351.This is to be distributed in ratio between the 650nm to 760nm than due to the light source S height of prior art because of the first light source S1 medium wavelength.To help improving first chromatic photoresist 351 after filtering the first light source S1, the brightness of first coloured light (ruddiness) L1 that is produced for this reason.
Above-mentioned inventive embodiments is first chromatic photoresist (red photoresistance) 351 direction as an illustration with chromatic photoresist 35.Yet when practical application, this chromatic photoresist 35 also can be one second chromatic photoresist (green photoresistance), 353 or 1 the 3rd chromatic photoresist (blue photoresistance) 355.And according to chromatic photoresist 35 (first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355), the difference of the first coloured light L1, the second coloured light L2 of the generation of filtering and the wave spread of the 3rd coloured light L3.Carry out the adjustment of the optical path difference of hole transport implanted layer 431 and/or electric transmission implanted layer 433.
For example, hole transport implanted layer 431 on first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355 is respectively the integral multiple of the wavelength of first coloured light (ruddiness) L1 (650nm to 760nm), second coloured light (green glow) L2 (500nm to 560nm) and the 3rd coloured light (blue light) L3 (450nm to 480nm).And the electric transmission implanted layer 433 on first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355 is respectively 1/2nd integral multiple of first coloured light (ruddiness) L1 (650nm to 760nm), second coloured light (green glow) L2 (500nm to 560nm) and the 3rd coloured light (blue light) L3 (450nm to 480nm) and wavelength.
In other words, electric transmission implanted layer 433 and hole transport implanted layer 431 and optical path difference are filtered the wave-length coverage of the coloured light (the first coloured light L1, the second coloured light L2 and the 3rd coloured light L3) that produces and are adjusted according to chromatic photoresist 35.Wherein the optical path difference of hole transport notes layer 431 is the integral multiple of the wavelength of coloured light (L1, L2, L3), and the optical path difference of electric transmission implanted layer 433 then is the integral multiple of coloured light (L1, L2, L3) 1/2nd wavelength.
To cause the organic EL component 40 on first chromatic photoresist 351 to produce one first light source S1 for this reason; Organic EL component 40 on second chromatic photoresist 353 produces a secondary light source S2; And the organic EL component 40 on the 3rd chromatic photoresist 355 produces one the 3rd light source S3.And it is one first coloured light L1 that this first light source S1 will be filtered into after penetrating first chromatic photoresist 351; It is one second coloured light L2 that secondary light source S2 will be filtered into after penetrating second chromatic photoresist 353; And the 3rd light source S3 will to be filtered into after penetrating the 3rd chromatic photoresist 355 be one the 3rd coloured light L3.
The above-mentioned hole transport implanted layer 431 and/or the optical path difference of electric transmission implanted layer 433 can be adjusted by the selection that thickness (d1, d2) and material refractive index (n1, n2) thereof are set of hole transport implanted layer 431 and/or electric transmission implanted layer 433.For example, if the wavelength that chromatic photoresist 35 filters the coloured light that produces is λ
1The time, can make the optical path difference of hole transport implanted layer 431 meet n
1d
1=m λ
1, wherein m is a positive integer, the optical path difference of electric transmission implanted layer 433 then meets
Wherein n is a positive integer.In other words, making the optical path difference of hole transport implanted layer 431 and/or electric transmission implanted layer 433, is λ to wavelength
1Coloured light meet the condition of a constructive interference.
Via the material of hole transport implanted layer 431 and/or the change of thickness is set, reach the purpose of the optical path difference of adjusting hole transport implanted layer 431 as mentioned above.For this reason, may make that set hole transport implanted layer 431 has the different thickness that is provided with on win chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355.And first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355 set hole transport implanted layers 431 also can be selected by different materials made.Certainly, for set electric transmission implanted layer 433 on first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355, thickness is set for it and material is also different.
Moreover, see also Fig. 5 and shown in Figure 6, be respectively the generalized section and the section construction generalized section of further embodiment of this invention.As shown in the figure, Organic Light-Emitting Device 401 mainly is provided with at least one organic EL component 40 in a colored filter 30.The embodiment of the invention and Fig. 3 and different part embodiment illustrated in fig. 4 are, are not provided with electric transmission implanted layer 433 in the organic EL component 40.
Because, be not provided with electric transmission implanted layer 433 in the structure of organic EL component 40.Therefore, the internal structure of organic EL component 40 is the stacked of first electrode 41, hole transport implanted layer 431, organic luminous layer 43 and second electrode 45 in regular turn.Only need the optical path difference of the hole transport implanted layer 431 of organic EL component 40 inside is adjusted.For example, make that the optical path difference of hole transport implanted layer 431 is chromatic photoresist 35 (first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355), the integral multiple of each coloured light (L1, L2, the L3) wavelength that produces that filters.
At last, see also Fig. 7 and shown in Figure 8, be respectively the generalized section and the section construction generalized section of further embodiment of this invention.As shown in the figure, Organic Light-Emitting Device 403 mainly is provided with at least one organic EL component 40 in a colored filter 30.The embodiment of the invention and Fig. 3 and the different part of embodiment shown in Figure 4 are, are not provided with hole transport implanted layer 431 in this organic EL component 40.
Wherein, the formation of organic EL component 40 is the stacked of first electrode 41, organic luminous layer 43, electric transmission implanted layer 433 and second electrode 45 in regular turn.Only need the optical path difference of electric transmission implanted layer 433 is adjusted, just can reach the purpose that improves Organic Light-Emitting Device 403 luminosity.For example, can make that the optical path difference of electric transmission implanted layer 433 is chromatic photoresist 35 (first chromatic photoresist 351, second chromatic photoresist 353 and the 3rd chromatic photoresist 355), 1/2nd integral multiple of each coloured light (L1, L2, the L3) wavelength that produces of filtering.
Again, in above-mentioned all embodiment to carry out the Organic Light-Emitting Device 400 of light color filtering as inventive embodiment by colored filter 30.Yet when practical application, use colored filter 30 to carry out the Organic Light-Emitting Device of light color filtering with being not limited to, for an organic EL component that can directly produce ruddiness, green glow or blue light, also can pass through the adjustment of the optical path difference of hole transport implanted layer and/or electric transmission implanted layer, reach the derivation efficient that improves ruddiness, green glow and blue light that it produced.
