Embodiment
For making those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, electroluminescent device provided by the invention and manufacture method, display base plate and display unit are described in detail.
The vertical view of the electroluminescent device that Fig. 3 provides for the embodiment of the present invention one, Fig. 4 be in Fig. 3 B-B to sectional view, as shown in Figure 3 and Figure 4, this electroluminescent device comprises: substrate 1 and pixel define layer 2, wherein, pixel defines the top that layer 2 is formed at substrate 1, and pixel defines on layer 2 and is formed with pixel openings matrix, this pixel openings matrix comprises multiple pixel openings 3, electroluminescence layer 4 is formed in pixel openings 3, wherein be in the electroluminescence layer 4 of the corresponding same color of whole pixel openings 3 of same row, be in the whole pixel openings of same row 3 aperture area that at least there is a pixel openings 3 and other pixel openings 3 unequal.
In the present embodiment, unequal owing to being in the whole pixel openings of same row 3 aperture area that at least there is a pixel openings 3 and other pixel openings 3, therefore when adopt row coating mode instil electroluminescent material solution and in same row, the amount of the electroluminescent material solution of each pixel openings 3 correspondence is identical time, through super-dry process with after electroluminescent material solution is become electroluminescence layer 4, be in whole electroluminescence layers 4 of same row the thickness that at least there is an electroluminescence layer 4 and other electroluminescence layers 4 unequal, the thickness being now in whole electroluminescence layers 4 of same row is not exclusively equal, thus make the brightness irregularities that this row electroluminescence layer 4 produces when luminescence.Although now may produce some somes mura in electroluminescent device because of brightness irregularities, the striped mura in electroluminescent device can be desalinated largely.By in this electroluminescent device applications to display unit time, because a mura region is relatively little, be therefore difficult to distinguish out by naked eyes, and then the visual effect of display unit can not be affected.
In this enforcement alternatively, the aperture area being in each pixel openings in whole pixel openings of same row is all unequal, and correspondingly, the thickness being in each electroluminescence layer in whole electroluminescence layers of same row is all unequal.Now, the probability of this electroluminescent device generation striped mura can reduce relatively.
Alternatively, the aperture area of pixel openings 3 is formed with area ratio a with the area of reference pre-set, and the span of area ratio a is: 0.98≤a≤1.02, and namely the knots modification of the aperture area of each pixel openings 3 is between-2% ~ 2% of area of reference.Preferably, the span of area ratio a is: 0.995≤a≤1.005, and namely the knots modification of the aperture area of each pixel openings 3 is between-0.5% ~ 0.5% of area of reference.Above-mentioned setting is under the display effect in order to ensure not affect display unit, is effectively desalinated by striped mura.
Alternatively, the aperture area being in each pixel openings 3 in whole pixel openings 3 of same row is all unequal.Wherein, when the amount of the electroluminescent material solution in each pixel openings 3 correspondence is identical, then, correspondingly after super-dry process, the thickness being in each electroluminescence layer 4 in whole electroluminescence layers 4 of same row is all unequal.
In addition, as another alternatives in the present embodiment, in the present embodiment, not only be in the whole pixel openings 3 in same row that at least to there is a pixel openings 3 different from the aperture area of other pixel openings 3, and it is unequal with the volume of other electroluminescence layers 4 at least to there is an electroluminescence layer 4 in the whole electroluminescence layers 4 being in same row.Namely, when the mode adopting row to be coated with instils electroluminescent material solution, the amount being in the electroluminescent material solution of each pixel openings 3 correspondence in same row is not exclusively equal.Now, the thickness that also can realize the whole electroluminescence layers 4 being in same row is not exclusively equal.
The process not exclusively equal to the amount realizing the electroluminescent material solution be in same row in each pixel openings 3 below in conjunction with accompanying drawing is described in detail.
Fig. 5 is the schematic diagram of nozzle instillation electroluminescent material solution, as shown in Figure 5, the volume of the electroluminescent material solution that nozzle oozes at every turn can be controlled by voltage sub-prime, when there being driving voltage to be loaded into voltage sub-prime, the raw deformation of the voltage sub-prime meeting sell of one's property, thus control oozing of the electroluminescent material solution of certain volume.Suppose in the present embodiment in each pixel openings 3, to need instillation four electroluminescent material solution, the volume often dripping electroluminescent material solution can be controlled by the driving voltage of of a correspondence complete waveform, such as, when the magnitude of voltage of first driving voltage is less, then the electroluminescent material solution that the corresponding drop volume produced is less.In Figure 5, the voltage of four corresponding four complete waveform of electroluminescent material solution.By adjusting at least one voltage, thus the dropped amount of electroluminescent material solution in respective pixel opening 3 can be controlled.Nozzle just moves to above the next line pixel openings 3 of respective column after generation four electroluminescent material solution, and repeats above-mentioned dropping liquid process.
After the instillation process of electroluminescent material solution, process to form electroluminescence layer 4 by drying.It should be noted that, when changing the dropped amount of electroluminescent material solution in pixel openings 3, for avoiding a mura to highlight, therefore in pixel openings 3, the knots modification of the dropped amount of electroluminescent material solution can not be excessive.Alternatively, the volume of the final electroluminescence layer 4 formed is formed with volume ratio b with the reference volume pre-set, and the span of volume ratio b is: 0.98≤b≤1.02.Namely the knots modification of the volume of each electroluminescence layer 4 is between-2% ~ 2% of reference volume.Preferably, the span of volume ratio b is: 0.995≤b≤1.005, and namely the knots modification of the volume of each electroluminescence layer 4 is between-0.5% ~ 0.5% of reference volume.
In the present embodiment, alternatively, the electroluminescence layer of corresponding same color and the incomplete same pixel openings random distribution in pixel openings matrix of aperture area, now, the probability that in electroluminescent device, this electroluminescent device produces striped mura can reduce relatively.
