Specific embodiment
To make the purpose of the present invention, technical solution and advantage are clearer, with reference to the accompanying drawing to embodiment of the present invention
It is described in further detail.Obviously, described embodiment is a part of the embodiments of the present invention, rather than whole implementation
Example.Based on described the embodiment of the present invention, those of ordinary skill in the art are obtained under the premise of being not necessarily to creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment one
As shown in Figs. 1-2, which show a kind of Full-color OLED display provided by the invention, the Full-color OLED display packets
It includes including substrate 1, the chromatic filter layer 2 on the substrate 1 and black matrix layer 3 and is set to the chromatic filter layer 2 and black
WOLED display layer 6 in matrix layer 3；The chromatic filter layer 2 includes red filter area 21, green filter area 22 and blue filter
Light area 23；The thickness in the red filter area 21 is less than the thickness in the green filter area 22.Specifically, in the present embodiment,
Flatness layer 4 and water oxygen barrier layer 5 are additionally provided between the chromatic filter layer 2 and black matrix layer 3 and WOLED display layer 6.In this way,
Thickness by reducing red filter area 21 makes its thickness be less than green filter area 22, and it is right to effectively reduce red filter area 21
The absorption of feux rouges improves the light extraction efficiency of WOLED display layer 6 to improve the light extraction efficiency of feux rouges.
Further, as shown in figure 3, since the thickness in red filter area 21 is smaller, if directly coating is primary flat
Smooth layer 4 then segment difference easy to form, and then the arrangement and cabling of WOLED display layer 6 are influenced, reduce product quality.Therefore, at this
In embodiment, the flatness layer 4 includes the first flatness layer 41 and the second flatness layer 42, and first flatness layer 41 is set to described red
On color filter area 21, it is configured to the thickness difference in compensation red filter area 21 and green filter area 22；Second flatness layer 42 covers
It is placed in first flatness layer 41, chromatic filter layer 2 and black matrix layer 3.That is the mode being coated with twice is first passed through to come
Flatness layer 4 is formed, the first coating forms the first flatness layer 41 for being located at red filter area 21, and the first flatness layer 41 can be mended effectively
The thickness difference in red filter area 21 Yu green filter area 22 is repaid, such as makes thickness and the red filter area 21 of the first flatness layer 41
The sum of thickness it is equal with the thickness in green filter area 22, in this way, would not occur after the first flatness layer 41 of coating biggish recessed
Convex injustice, therefore second of coating can be carried out and form the second flatness layer 42, second flatness layer 42 is just covered in described the
In one flatness layer 41, chromatic filter layer 2 and black matrix layer 3, so as to which the planarization effect of the second flatness layer 42 is effectively ensured
Fruit guarantees the arrangement and production of water oxygen barrier layer 5 and WOLED display layer 6.
Embodiment two
The present embodiment is identical as previous embodiment principle, and structure is similar, and difference is only that the WOLED display layer 6 is matched
It is set to and white light is issued by compound orange light and blue light；Wherein, the intensity for issuing orange light is greater than the intensity of blue light.In this way, by
It is directed through blue filter area 23 in blue light, light extraction efficiency is relatively high, can also be with so that the intensity of orange light is larger
The Distribution utilization for preferably realizing light, improves the light extraction efficiency of WOLED display layer 6.
Further, as shown in figure 4, in the lesser situation of blue light strength, so that the thickness in the blue filter area 23
Transmitance is improved, to guarantee that blue light goes out less than the thickness in the green filter area 22 so as to reduce the absorption to blue light
Light rate.For example, the green filter area 22 is with a thickness of 2 ± 0.1 μm, and the thickness in red filter area 21 and blue filter area 23 can
Think 1 ± 0.1 μm.
Similarly, in the present embodiment, further, due to the thickness in red filter area 21 and blue filter area 23 compared with
It is small, if therefore be directly coated with a flatness layer 41 then segment difference easy to form, and then influence WOLED display layer 6 arrangement and
Cabling reduces product quality.Therefore, the flatness layer 4 also includes the first flatness layer 41 and the second flatness layer 42, and described first
Flatness layer 41 accordingly be set to the red filter area 21 and blue filter area 23 on, be configured to compensation red filter area 21 with it is green
The thickness difference of color filter area 22 and the thickness difference in blue filter area 23 and green filter area 22.Similarly, described second is flat
Layer 42 is covered in first flatness layer 41, chromatic filter layer 2 and black matrix layer 3.That is it first passes through and to be coated with twice
Mode forms flatness layer 4, and the first coating forms the first flatness layer 41 being located in red filter area 21 and blue filter area 23,
First flatness layer 41 can with the thickness difference in effective compensation red filter area 21, blue filter area 23 and green filter area 22, in this way,
Being coated with after the first flatness layer 41 would not occur biggish uneven, therefore can carry out second of coating to form second flat
Layer 42, second flatness layer 42 is just covered in first flatness layer 41, chromatic filter layer 2 and black matrix layer 3, thus
It can effectively ensure that the flattening effect of the second flatness layer 42, guarantee the arrangement and system of water oxygen barrier layer 5 and WOLED display layer 6
Make.
More specifically, the viewing area setting of the corresponding Full-color OLED display of the flatness layer 4.I.e. described first flatness layer 41
It only corresponds to red filter area 21 and/or blue filter area 23 to be arranged, to pattern flatness layer 4, similarly, first flatness layer
41 also only correspond to viewing area setting, to pattern flatness layer 4.Certainly, in a further embodiment, second flatness layer 42
It can not be patterning planarization, but the mode that selection integrally covers is arranged.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
Therefore limitations on the scope of the patent of the present invention are interpreted as, as long as skill obtained in the form of equivalent substitutions or equivalent transformations
Art scheme should all be fallen within the scope and spirit of the invention.
