Specific embodiment

It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not For limiting the application.

A kind of inkjet printing methods provided by the present application, can be applied in application environment as shown in Figure 1.Wherein, it sprays Black printing terminal 102 is communicated by network with ink jet printing device 104.Wherein, inkjet printing terminal 102 can with but it is unlimited Then various personal computers, laptop, smart phone, tablet computer and portable wearable device.Inkjet printing is set Standby 104 for making OLED device.

It should be noted that certain functional materials can use the side of inkjet printing in the manufacture craft of OLED device Formula is made.For example, hole injection layer (Hole Inject Layer, HIL), hole transmission layer (Hole in OLED device Transport Layer, HTL), luminescent layer (Emitting Material Layer, EML) etc., hole injection layer, hole pass The pixel of defeated layer and luminescent layer hole, can squeeze into functional material ink by way of inkjet printing.Wherein, pixel hole has Certain ink capacity needs to set ink total volume for the ink capacity, that is, cheat and instill to pixel in inkjet printing After several ink droplets, the sum of several droplet volumes needs match with the ink total volume.

The application in order to facilitate understanding by those skilled in the art, below with reference to Fig. 2 to Fig. 4, to the embodiment of the present application Ink jet printing device is illustrated.

Fig. 2 is a kind of schematic diagram of a scenario of inkjet print head production OLED device.It can be seen that inkjet print head 202 204 printing function material inks 206 are cheated to the pixel of OLED device.

Fig. 3 is a kind of structural schematic diagram of inkjet print head.It can be seen that inkjet print head 302 includes multiple sprays Mouth 3021, nozzle 3021 are used to spray ink droplet, under the control of different voltages waveform, nozzle 3021 according to the control of voltage waveform Spraying every droplet volume for dripping ink droplet, there may be differences.Inkjet print head 302 is connected with fill ink part 304, and ink is filled out Part 304 is filled for providing functional material ink to nozzle 3021.

Fig. 4 is a kind of structural schematic diagram of nozzle.It can be seen that including ink storage chamber 4021, excitation cavity in nozzle 402 4022, piezoelectric ceramic plate 4023.Ink storage chamber 4021 is used to store the functional material ink of fill ink part offer, and to excitation cavity 4022 input function material inks；Excitation cavity 4022 is used to store the functional material ink of the input of ink storage chamber 4021；When to piezoelectricity When ceramic wafer 4023 applies certain voltage, piezoelectric ceramic plate 4023 then can deformation occurs, and squeeze excitation cavity 4022；It is squeezed Excitation cavity 4022, can squeeze out the functional material ink wherein stored, ink droplet 403 be formed, however, ink droplet 403 is injected into In the pixel hole of OLED device 404.In order to realize that continuous inkjet, piezoelectric ceramic plate 4023 need to carry out reciprocal in print out task Deformation.In order to realize the reciprocal transformation of piezoelectric ceramic plate 4023, then need to piezoelectric ceramic plate 4023 according to the certain intervals time, Apply the voltage of certain duration.

It should be added that the ink droplet more dripped may be instilled for each pixel hole in a print out task. And due to the craft precision of nozzle difference, even if the droplet volume that different spray nozzles spray ink droplet may according to same voltage waveform There is some difference.

In existing OLED device InkJet printing processes, each nozzle the control of identical voltage waveform spray more drop ink droplets it Afterwards, this species diversity can then accumulate, and lead to differing greatly for the ink volume in the corresponding pixel hole of nozzle, what inkjet printing obtained The film of OLED device then can became uneven, seriously affect the performance of OLED device.

For example, setting the corresponding droplet volume deviation range of voltage waveform as [9.7,10.3], corrected by ink-jet ink-droplet, Learn that the actual droplet volume of nozzle A is 10.1pl (picoliters), the actual droplet volume of nozzle B is 10.3pl, it is assumed that is currently needed Three drop ink droplets are sprayed, the ink total amount that nozzle A sprays is 10.1*3=30.3pl, and the ink total amount that nozzle B sprays is 10.3*3=30.9pl there are the volume differences of 30.9-30.3=0.6pl for the two.

In one embodiment, as shown in figure 5, providing a kind of inkjet printing methods, it is applied in Fig. 1 in this way It is illustrated for inkjet printing terminal 102, comprising the following steps:

Step S502 obtains candidate droplet volume.

Wherein, the candidate droplet volume in step S502 includes the nozzle of ink jet printing device respectively according to multiple voltage waves The practical droplet volume sprayed when shape ink-jet.Each nozzle is according to multiple voltage waveform ink-jets, the available multiple voltages of correspondence Multiple droplet volumes of waveform.When each nozzle is according to multiple voltage waveform ink-jets, multiple ink of available multiple nozzles Drop volume, as candidate droplet volume.For example, ink jet printing device includes 128 nozzles, 128 nozzles are respectively according to 16 A waveform carries out ink-jet, and 128*16=2048 candidate droplet volume can be obtained.

Specifically, the available each nozzle of inkjet printing terminal 102 is according to the practical ink droplet sprayed of different voltages waveform Volume can further screen candidate droplet volume as candidate droplet volume so as to subsequent.

Obtain candidate droplet volume concrete mode can there are many.For example, multiple voltage waveforms can be set first, adopt Ink droplet titration correction is carried out with nozzle of multiple voltage waveform to ink jet printing device, obtains the correspondence different voltages wave of nozzle The nozzle is corresponded to the droplet volume of each voltage waveform as candidate droplet volume by the droplet volume of shape.It can also carry out ink Drop titration correction, obtain the droplet volume of correspondence different voltages waveform of nozzle after, further calculate multiple droplet volumes with The deviation of standard droplet volume, and according to the deviation, several preferred droplet volumes are filtered out, as candidate ink droplet body Product.Certainly, those skilled in the art can obtain candidate droplet volume using other modes according to actual needs, and the application is implemented Example to specific candidate droplet volume acquisition modes with no restriction.

Step S504 filters out multiple target droplet volumes from the candidate droplet volume；The multiple target ink droplet The sum of volume is matched with the ink total volume of setting.

Wherein, the target droplet volume in step S504 includes that the ink total volume of sum and setting is matched several Candidate droplet volume.

Wherein, the ink total volume in step S504 includes the volume for the ink for needing to spray in current print out task.Ink Water total volume can be set according to the ink capacity that pixel is cheated.For example, the ink capacity in pixel hole is 30.3pl, can set The ink total volume of current print out task is 30.3pl.

Specifically, inkjet printing terminal 102 can extract multiple candidate droplet volumes first and sum, and judge candidate ink Whether the ink total volume of the sum of drop volume and setting matches with preset ink total volume.If so, being extracted conduct Target droplet volume；It sums if it is not, then extracting other candidate droplet volume again, carries out the judgement processing of next round.

Screening target droplet volume can be there are many specific processing mode.

For example, the candidate droplet volume for corresponding to same nozzle can be determined first in multiple candidate droplet volumes, Target droplet volume is searched in the candidate droplet volume of same nozzle.If can not be in the candidate droplet volume of the same nozzle Multiple target droplet volumes are got, the candidate droplet volume of other nozzles can be obtained further to increase alternative time Droplet volume is selected, then in the candidate droplet volume of same nozzle, and, in the candidate droplet volume of other nozzles, obtain mesh Mark droplet volume.

It, can also be according to same nozzle during searching target droplet volume in the candidate droplet volume of same nozzle Candidate droplet volume deviation, carry out classification searching.For example, can be first in the lesser candidate droplet volume of deviation Multiple target droplet volumes are searched, multiple target droplet volumes can not be got in the lesser candidate droplet volume of deviation When, the biggish candidate droplet volume of deviation is further obtained, it is larger in the lesser candidate droplet volume of deviation and deviation Candidate droplet volume in, search multiple target droplet volumes.

It, can also be with during the candidate droplet volume of other nozzles is obtained to increase alternative candidate droplet volume Nozzle selection is carried out according to the distance between nozzle.For example, multiple target ink can not be got in the candidate droplet volume of nozzle A Drop volume then can further obtain the candidate droplet volume of adjacent nozzle B, in the candidate droplet volume and nozzle B of nozzle A Candidate droplet volume in, search multiple target droplet volumes.

It should be noted that above example is merely to illustrate the screening means used for different actual conditions, and The non-restriction to Screening Treatment.Those skilled in the art can use various means according to actual needs, filter out summation after with The matched multiple target droplet volumes of ink total volume.

Step S506 obtains the corresponding nozzle-waveform combination of each target droplet volume.

Wherein, nozzle-waveform combination in step S506 includes the information as composed by nozzle mark and voltage waveform.Spray Mouth is identified for identifying the entity nozzle in ink jet printing device.For example, a target droplet volume v₁Corresponding nozzle-waveform M0001 is combined, can be " nozzle INJ₀₀₁Voltage waveform V₁", indicate nozzle INJ₀₀₁Corresponding entity nozzle, according to voltage wave Shape V₁When carrying out ink-jet, the volume for spraying ink droplet is target droplet volume v₁。

Specifically, since the nozzle that candidate droplet volume is ink jet printing device carries out ink droplet according to the voltage waveform of setting Titration correction obtains, and therefore, each candidate's droplet volume has corresponding nozzle mark and voltage waveform.Inkjet printing terminal 102 are directed to target droplet volume, it can get corresponding nozzle mark and voltage waveform, and formed a spray Mouth-waveform combination.Multiple target droplet volumes has then accordingly obtained multiple nozzle-waveform combinations.

Step S508 sends the corresponding multiple nozzle-waveform combinations of the multiple target droplet volume to inkjet printing and sets It is standby, print out task is executed according to the nozzle-waveform combination for the ink jet printing device.

Specifically, multiple nozzle-waveform combinations can be sent to ink jet printing device 104 by inkjet printing terminal 102.Spray Black printing device 104 then can execute print out task according to multiple nozzle-waveform combinations.More specifically, ink jet printing device 104 can select nozzle to identify corresponding target entity spray according to the mark of the nozzle in nozzle-waveform combination and voltage waveform Mouth, control target entity nozzle carry out ink-jet according to the voltage waveform.For multiple nozzle-waveform combinations, ink jet printing device 104 can choose multiple target entity nozzles, carry out ink-jet according to different voltage waveforms.

As previously mentioned, multiple nozzle-waveform combinations correspond respectively to multiple target droplet volumes, and multiple target ink droplet The sum of volume and the ink total volume of setting match.In other words, ink jet printing device is according to multiple nozzle-waveform selections pair The target entity nozzle answered, and the target entity nozzle is controlled, according to corresponding voltage waveform, some pixel hole is sprayed Ink, the sum of the droplet volume of the more drop ink droplets sprayed also correspondingly match with the ink total volume of setting.To OLED The ink total volume injected in each pixel hole on device, otherness will reduce, and ensure that film in OLED device Thickness reaches unanimity.

For example, it is assumed that the ink total volume of current print out task is 30.3pl, for three nozzles-waveform combination M0001, M0002 and M0003, nozzle-waveform combination M0001 are [nozzle INJ₀₀₁Voltage waveform V₁], nozzle-waveform combination M0002 is [nozzle INJ₀₀₂Voltage waveform V₁], nozzle-waveform combination M0003 is [nozzle INJ₀₀₂Voltage waveform V₂].Ink jet printing device When executing print out task according to three nozzles-waveform combination, specifically, according to nozzle-waveform combination M0001 [nozzle INJ₀₀₁Voltage waveform V₁], select nozzle INJ₀₀₁Corresponding nozzle is according to voltage waveform V₁Ink-jet sprays the droplet volume of ink droplet For 10.0pl；According to nozzle-waveform combination M0002 [nozzle INJ₀₀₂Voltage waveform V₁], select nozzle INJ₀₀₂Corresponding nozzle According to voltage waveform V₁Ink-jet, the droplet volume for spraying ink droplet is 10.1pl；According to nozzle-waveform combination M0003 [nozzle INJ₀₀₂Voltage waveform V₂], select nozzle INJ₀₀₂Corresponding nozzle is according to voltage waveform V₂Ink-jet sprays the droplet volume of ink droplet For 10.2pl.The droplet volume v=10.0+10.1+10.2=30.3pl of the three drop ink droplets sprayed as a result, appoints with current printing The ink total volume of business is 30.3pl matching.So analogize, for OLED device each pixel cheat, it is available with The sum of matched droplet volume of 30.3pl.

In above-mentioned inkjet printing methods, by overall with setting ink after filtering out summation in candidate droplet volume The matched multiple target droplet volumes of product, and the corresponding nozzle-waveform combination of multiple target droplet volumes is obtained, by multiple sprays Mouth-waveform combination is sent to ink jet printing device, and ink jet printing device controls each nozzle according to right according to nozzle-waveform combination When the waveform answered carries out ink-jet, the sum of the droplet volume for more drop ink droplets that each nozzle sprays, with the ink total volume of setting It matches, so that the ink volume in each pixel hole in OLED device reaches unanimity, solves OLED device ink material Expect that the uniformity of film forming is poor, influences the problem of performance of OLED device.

In another embodiment, as shown in fig. 6, provide one kind filters out multiple target ink droplets from candidate droplet volume The flow diagram of the step of volume, candidate's droplet volume are identified with corresponding nozzle, and the step S504 can have Body includes following sub-step:

Sub-step S11 determines nozzle mark to be processed in multiple nozzles mark；

Sub-step S12 judges in the corresponding candidate droplet volume of the nozzle mark to be processed, if comprising the multiple Target droplet volume；If so, S13 is thened follow the steps, if it is not, thening follow the steps S14；

Sub-step S13 identifies in corresponding candidate droplet volume in the nozzle to be processed, extracts the multiple target ink Drop volume；

Sub-step S14 obtains the adjacent nozzle mark of the nozzle mark to be processed, and identifies in the nozzle to be processed Candidate droplet volume and the adjacent nozzle mark candidate droplet volume in, extract the multiple target droplet volume.

Specifically, its corresponding nozzle mark can be marked for multiple candidate droplet volumes, from multiple candidate ink droplets When volume screens target droplet volume, a nozzle mark can be determined first, is identified as nozzle to be processed.Then, more In a candidate's droplet volume, the multiple candidate droplet volumes for corresponding to nozzle to be processed mark are determined, and judge multiple candidate In droplet volume, if include the multiple target droplet volumes for the ink total volume that summing value is setting.

It, then can be with if including multiple target droplet volumes in the corresponding candidate droplet volume of nozzle to be processed mark Directly therefrom extract multiple target droplet volumes.

If nozzle to be processed identifies in corresponding candidate droplet volume, not comprising there are multiple target droplet volumes, then need The adjacent nozzle mark for further determining that nozzle mark to be processed identifies corresponding candidate droplet volume in nozzle to be processed, And in the candidate droplet volume of adjacent nozzle mark, that is, in the candidate droplet volume of two nozzles mark, extract more A target droplet volume.

In actual inkjet printing scene, if multiple target droplet volumes are related to different nozzles, it may need Inkjet print head is moved to adjust nozzle location, to increase the print time.Accordingly, it is preferred that printing type is using same One nozzle carries out ink-jet.Correspondingly, when screening target droplet volume, then preferentially from the candidate droplet volume of same nozzle mark In, filter out target droplet volume.However, if target ink droplet can not be filtered out in the candidate droplet volume of a certain nozzle mark Volume can choose adjacent nozzle mark, the selected part target ink droplet body in the candidate droplet volume of adjacent nozzle mark Product expands the selection source of candidate droplet volume, and increase obtains the probability of multiple target droplet volumes, while guaranteeing to increase again Add the excessive print time, improves the efficiency of inkjet printing.

In practical application, formula Σ (v can be passed through_n)=v_totalJudged.Wherein, v_nFor the candidate's ink currently chosen Drop volume, v_totalFor the ink total volume set for current print out task.By selecting multiple candidate droplet volumes and asking With, until obtain summing value be v_totalSeveral candidate droplet volume v_n, as multiple target droplet volumes.

In another embodiment, nozzle mark has a corresponding position, described in the acquisition in the sub-step S14 to The step of handling the adjacent nozzle of nozzle mark, can be with specifically:

Calculate separately other nozzles identify corresponding position and the nozzle to be processed identify between corresponding position away from From obtaining multiple distances；In the multiple distance, minimum range is determined；By the corresponding nozzle mark of minimum range, as institute State adjacent nozzle mark.

Wherein, said nozzle identifies corresponding position, may include identifying for recording nozzles in ink jet printing device The information of corresponding entity nozzle location.

Specifically, in order to determine that adjacent nozzle identifies, can determine that each nozzle identifies corresponding position first, calculate to The position of nozzle mark and the distance between the position of other nozzle marks are handled, thus obtains multiple distances, therefrom really Determine minimum range, the smallest nozzle of the positional distance identified with nozzle to be processed is identified, is identified as adjacent nozzle.

By identifying the nozzle mark of minimum range as adjacent nozzle, convenient for reducing spray when executing print out task The black print head mobile time to adjust nozzle, improve the efficiency of inkjet printing.

In practical application, a distance threshold can also be set, when minimum range is greater than the distance threshold, will not be selected Nozzle mark is taken to identify as adjacent nozzle, to avoid inkjet printhead movement apart from excessive.

In another embodiment, the candidate droplet volume has corresponding deviation, and the sub-step S12 can have Body are as follows:

Judge to identify in candidate droplet volume corresponding, with the first deviation N1 range in the nozzle to be processed, It whether include the multiple target droplet volume；Wherein, N1 >=0；If it is not, then further judging to identify in the nozzle to be processed In candidate droplet volume corresponding, with the second deviation N2 range, if include the multiple target droplet volume；Its In, N1 >=0 the N2 >；If it is not, then determining not including in the corresponding candidate droplet volume of the nozzle mark to be processed State multiple target droplet volumes.

Wherein, the deviation in above-mentioned steps may include the difference of candidate droplet volume Yu preset standard droplet volume Value.For example, candidate droplet volume is 10.2pl, preset standard droplet volume is 10.0pl, and deviation is 0.2pl.

Specifically, in order to promote screening efficiency, judge whether to wrap in the candidate droplet volume for nozzle to be processed mark When droplet volume containing target, multiple candidate droplet volumes with the first deviation N1 range can be determined first, multiple In candidate droplet volume, judge whether comprising the multiple target droplet volume.

If it is, multiple target droplet volumes can be extracted directly in multiple candidate droplet volume.

If it is not, then needing to further determine that multiple candidate droplet volumes with the second deviation N2 range, and judge In multiple candidate droplet volumes with the first deviation N1 range and multiple candidate ink droplets with the second deviation N2 range In volume, judge whether comprising the multiple target droplet volume.

If it is, multiple target droplet volumes can be extracted wherein.

If it is not, then can be determined that in the corresponding candidate droplet volume of nozzle to be processed mark, not comprising there is multiple targets Droplet volume.

In actual application scenarios, each nozzle has multiple candidate droplet volumes, if according to formula Σ (v_n)= v_total, whether judgement includes wherein multiple target droplet volumes, and the processing time spent then can be more.

For example, the ink total volume of current print out task is 30.3pl, corresponding standard droplet volume is 10.1pl, currently Nozzle identifies INJ₀₀₁Corresponding candidate's droplet volume is 9.7 to 10.3pl, to be judged whether in multiple candidate droplet volume There are multiple target droplet volumes, need to carry out multiple selection, summation, judgement processing.

Therefore, multiple target droplet volumes preferentially can be extracted in the lesser candidate droplet volume of deviation, to sieve While selecting target droplet volume, the processing time is reduced.

For example, ink total volume is 30.3pl, the first deviation is [0,0.1pl], and corresponding candidate's droplet volume is 10.0pl, 10.1pl and 10.2pl choose this three candidate droplet volume summations, the ink of 10.1+10.0+10.2=30.3pl Total volume is matched with the ink total volume 30.3pl of setting.

When multiple target droplet volumes can not be extracted in the lesser candidate droplet volume of deviation, then further exist The biggish candidate droplet volume of deviation extracts target droplet volume, to obtain in the candidate droplet volume that same nozzle identifies To target droplet volume.

In another embodiment, the step S502, can be with specifically:

It obtains the nozzle to be processed and identifies corresponding multiple practical droplet volumes, and, it obtains overall with the ink The corresponding standard droplet volume of product；Calculate the multiple practical droplet volumes and the standard ink droplet body that the nozzle to be processed identifies Long-pending deviation obtains multiple deviations；It obtains the practical droplet volume with the first deviation N1 range and there is institute The practical droplet volume for stating the second deviation N2 range identifies corresponding candidate droplet volume as the nozzle to be processed.

Wherein, above-mentioned practical droplet volume, the entity nozzle for corresponding to nozzle mark including ink jet printing device are passing through Cross the droplet volume obtained after ink droplet titration correction.

Wherein, above-mentioned standard droplet volume, including the intended volume of the every drop ink droplet set according to ink total volume.

Specifically, when obtaining candidate droplet volume, nozzle can be obtained first and identifies corresponding practical droplet volume, together When, available standard droplet volume.

Above it has been described that ink total volume v can be set according to current print out task_total.Then, according to ink Water total volume, then can set ink droplet drop number N, and standard droplet volume can then pass through formula v_total=v₀* N is obtained.

For example, the ink total volume of current print out task is 30.3pl, the droplet volume deviation range of an ink droplet exists [9.7,10.3] in the case where taking median 10.0, then need at least to spray three drop ink droplets, can just obtain the ink of 30.3pl. Thus may determine that N=3, correspondingly, standard droplet volume v₀It is then 30.3/3=10.1pl.

It is then possible to calculate the deviation between the multiple practical droplet volumes and standard droplet volume of nozzle mark.Root , can be according to formula for obtained multiple deviations | v₀-v_n|_{It is minimum}, choose the first deviation and the corresponding reality of the second deviation Border droplet volume, as candidate droplet volume, so that the difference of the candidate droplet volume and standard droplet volume chosen minimizes.

Entity nozzle corresponding with nozzle mark is sprayed according to the voltage waveform on triggering ink jet printing device Ink

Specifically, ink jet printing device 104 receives three nozzles-waveform combination M0001, M0002 and M0003.Wherein, Nozzle-waveform combination M0001 is [nozzle INJ₀₀₁Voltage waveform V₁], nozzle-waveform combination M0002 is [nozzle INJ₀₀₂Electricity Corrugating V₁], nozzle-waveform combination M0003 is [nozzle INJ₀₀₂Voltage waveform V₂].Ink jet printing device 104 is according to nozzle- Waveform combination M0001 [nozzle INJ₀₀₁Voltage waveform V₁], select nozzle INJ₀₀₁Corresponding nozzle is according to voltage waveform V₁Ink-jet, The droplet volume for spraying ink droplet is 10.0pl；According to nozzle-waveform combination M0002 [nozzle INJ₀₀₂Voltage waveform V₁], selection Nozzle INJ₀₀₂Corresponding nozzle is according to voltage waveform V₁Ink-jet, the droplet volume for spraying ink droplet is 10.1pl；According to nozzle-wave Shape combines M0003 [nozzle INJ₀₀₂Voltage waveform V₂], select nozzle INJ₀₀₂Corresponding nozzle is according to voltage waveform V₂Ink-jet, spray The droplet volume of ink droplet is 10.2pl out.The droplet volume v=10.0+ for the three drop ink droplets that ink jet printing device 104 sprays as a result, 10.1+10.2=30.3pl being that 30.3pl is matched with the ink total volume of current print out task.So analogize, for OLED device Each pixel of part is cheated, the sum of available and matched droplet volume of 30.3pl.

By above-mentioned inkjet printing methods so that in OLED device each pixel hole in ink volume tend to one It causes, solves the problems, such as that the uniformity of OLED device ink material film forming is poor, influences the performance of OLED device.

In another embodiment, the method also includes:

It specifically, may include having for being deformed under specific voltage, to squeeze excitation in ink jet printing device 104 A numerical control frequency converter can be set for the piezoelectric ceramic plate in the piezoelectric ceramic plate of chamber ink-jet, with adjustment.Due to multiple sprays Voltage waveform in mouth-waveform combination may be different, and when executing print out task, voltage waveform can then change.Therefore, exist When detecting that the voltage waveform in nozzle-waveform combination changes, can for variation after voltage waveform in voltage and Time, adjustment be applied to voltage ceramic plate voltage and apply the alive time, with change piezoelectric ceramic plate amplitude of deformation and Deformation frequencies, to change the droplet volume of the ink droplet of nozzle ejection.

Figure 10 is a kind of schematic diagram of optimization nozzle interior structure of the embodiment of the present application.It can be seen that the spray of optimization In mouth, in addition to including excitation cavity 1002 and piezoelectric ceramic plate 1004, it is additionally provided with a numerical control frequency converter 1006.Become by numerical control Frequency device 1006 can be directed to different voltage waveforms, adjust the voltage being applied on piezoelectric ceramic plate 1004 and apply alive Time, piezoelectric ceramic plate 1004 generate repetitive distortion to squeeze the dynamics of the ejection ink droplet of excitation cavity 1002 and then can mutually strain with the time Change, to change the droplet volume for spraying ink droplet.

The embodiment of the present application is deeply understood for the ease of those skilled in the art, is said below with reference to specific example It is bright.

Assuming that including multiple nozzles in current inkjet print head, corresponding nozzle mark is respectively INJ₀₀₁、 INJ₀₀₂、INJ₀₀₃、INJ₀₀₄、INJ₀₀₅And INJ₀₀₆.According to inkjet printing methods in the prior art, a voltage wave is received Shape V₁, each nozzle is according to voltage waveform V₁Ink-jet is carried out, obtained droplet volume is as shown in table 1 below:

						INJ₀₀₁	INJ₀₀₂	INJ₀₀₃	INJ₀₀₄
V₁	10.1	10.2	10.2	10.1
					V₁	10.1	10.2	10.2	10.1
V₁	10.1	10.2	10.2	10.1
