[0002] Inkjet printing is one of the main processes for manufacturing organic light-emitting diode (OLED) displays. It involves spraying ink onto a substrate material to create the OLED display. Before inkjet printing, it is often necessary to set the waveform corresponding to the printhead, and then use the waveform to control the printhead to eject a corresponding volume of ink, thus achieving inkjet printing.

[0003] However, in the actual inkjet printing process, since there are multiple nozzles on a printhead, the ink droplet volume in the multiple nozzles is different, which will cause a difference between the total amount of ink ejected by the printhead and the total amount of ink that needs to be ejected.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Inkjet printing is one of the main processes for manufacturing OLED displays. It involves spraying ink onto the substrate material of the display screen to create an organic self-emissive display. Before inkjet printing, it is often necessary to set the waveform corresponding to the printhead, and then use the waveform to control the printhead to eject a corresponding volume of ink, thus achieving inkjet printing.

[0033] However, in the actual inkjet printing process, since there are multiple nozzles on a printhead, the actual ink droplet volume filled in the multiple nozzles is different, which will cause a difference between the total amount of ink ejected by the printhead and the total amount of ink that needs to be ejected.

[0034] When there is a difference between the total amount of ink corresponding to the pixels on the display panel and the required total amount of ink, it will cause quality problems such as uneven display of the entire display panel.

[0035] To address the aforementioned technical problems, embodiments of this application provide an inkjet printing method, apparatus, electronic device, and storage medium. This inkjet printing method can reduce the difference between the actual ejected ink droplet volume and the required ejected ink droplet volume.

[0036] For a more detailed understanding of the inkjet printing method provided in the embodiments of this application, please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of the nozzle structure provided in the embodiment of this application.

[0037] like Figure 1 The nozzle shown includes an ink filling chamber 110 and multiple nozzles 120. The ink filling chamber 110 and multiple nozzles 120 are connected. The nozzles 120 can be filled with ink of a corresponding volume. Then, controlled by an electrical signal, the nozzles 120 spray ink into the pixel pits of the display substrate.

[0038] Please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the nozzle structure provided in the embodiment of this application.

[0039] The nozzle 120 includes an ink excitation chamber 121, a piezoelectric ceramic plate 122, and a CNC frequency converter 123.

[0040] Before inkjet printing, the ink is stored in the ink excitation chamber 121. The electronic device controls the digital frequency converter 123 to output the corresponding voltage, thereby controlling the piezoelectric ceramic plate 122 to undergo corresponding deformation. The deformed piezoelectric ceramic plate 122 will squeeze the ink excitation chamber 121, thereby causing the ink in the ink excitation chamber 121 to be ejected at a certain frequency.

[0041] When inkjet printing ends, the electronic device can control the CNC inverter 123 to stop the piezoelectric ceramic plate 122 from pressurizing the ink excitation chamber 121, thereby stopping the nozzle from spraying ink.

[0042] Please refer to the following: Figure 3 , Figure 3 This is a waveform diagram provided in an embodiment of this application.

[0043] Within the CNC frequency converter 123, it is often necessary to set the corresponding voltage-time combination waveform, such as... Figure 3 As shown, the horizontal axis represents time and the vertical axis represents voltage.

[0044] When the CNC frequency converter 123 operates according to the waveform, it outputs corresponding voltages to the piezoelectric ceramic plate 122 at different times, thereby causing the piezoelectric ceramic plate 122 to deform. This causes the ink excitation chamber 121 to eject a corresponding volume of ink.

[0045] In this embodiment of the application, taking a unit to be printed as an example, the electronic device obtains the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle under the first waveform; determines the target nozzle corresponding to the unit to be printed based on the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle; and then determines the total ink droplet volume based on the first ink droplet volume corresponding to the target nozzle.

[0046] If the total droplet volume does not meet the preset total droplet volume of the printing unit, the nozzle to be adjusted is determined; the first waveform corresponding to the nozzle to be adjusted is adjusted to obtain the second waveform corresponding to the nozzle to be adjusted; finally, inkjet printing is performed on the printing unit according to the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted.

[0047] Ultimately, the ink volume ejected by the target nozzle corresponding to the unit to be printed and the ink volume ejected by the nozzle to be adjusted are added together. The resulting sum is the same as the preset total ink volume corresponding to the unit to be printed, thereby reducing the difference between the total ink droplet volume ejected by the nozzle corresponding to the unit to be printed and the preset total ink droplet volume of the unit to be printed.

[0048] When the unit to be printed is a pixel, if the actual total ink volume corresponding to each pixel is the same as the preset total ink volume for the entire display panel to be printed, then the final printed display panel will have smaller differences between pixels, the entire display panel will look more uniform, and the display effect of the display panel will be better.

[0049] For a more detailed understanding of the inkjet printing method provided in the embodiments of this application, please refer to [link / reference]. Figure 4 , Figure 4 This is a first flowchart illustrating the inkjet printing method provided in this application embodiment. The inkjet printing method may include the following steps:

[0050] 210. Obtain the preset droplet volume of the unit to be printed and the first droplet volume of the nozzle corresponding to the first waveform.

[0051] Different types of printing units correspond to different preset ink droplet volumes. For example, if the size of printing unit A and printing unit B are different, then the preset ink droplet volumes corresponding to printing unit A and printing unit B are also different.

[0052] The electronic device can obtain the preset ink droplet volume of the cell to be printed. The preset ink droplet volume is the volume dropped into the corresponding filling hole of the cell to be printed in one go. For example, if the volume dropped in one go is 10.0 plc (pixels), then the preset ink droplet volume of the cell to be printed is 10.0 plc.

[0053] As described above, a printhead contains multiple nozzles, and these nozzles can fill a certain volume of ink under the first waveform. The electronic equipment can determine the actual volume of the first ink droplet filled by each nozzle under the first waveform.

[0054] For example, the electronic device drives the chamber of the nozzle to deform according to the first waveform, thereby filling the ink and determining the volume of the first ink droplet filled in the nozzle.

[0055] In some implementations, the nozzle waveform is adjusted before inkjet printing. Once a set of waveform parameters is determined, the volume of the ejected ink droplets is fixed on the nozzle of the inkjet printhead.

[0056] Once the first waveform is determined, the electronic device can control multiple nozzles to draw ink based on the first waveform, and then the electronic device can determine the corresponding first ink droplet volume in each nozzle. Theoretically, the first ink droplet volume filled by the nozzle controlled by the first waveform should be equal to the preset ink droplet volume. However, in actual scenarios, the first ink droplet volume of some nozzles may differ from the preset ink droplet volume. For example, the ink droplet volume in the nozzle may be larger or smaller than the target ink droplet volume.

[0057] For example, if the preset droplet volume is 10.0 pl (picoliter), the actual volume of the first droplet filled in the nozzle is 10.1 pl, which is greater than the preset droplet volume.

[0058] In some implementations, the electronic device can acquire the volume of a first ink droplet within each nozzle, which is the actual volume of ink droplets drawn by the nozzle. For example, the first ink droplet volume corresponding to nozzle 1 is 10.1 pl, and the first ink droplet volume corresponding to nozzle 2 is 9.9 pl.

[0059] Since the first waveform corresponding to multiple nozzles is determined, the actual volume of the first ink droplet drawn into the nozzle is the volume of the ink droplets that will be ejected subsequently. For example, if the volume of the first ink droplet corresponding to nozzle 1 is 10.1pl, then nozzle 1 will subsequently eject an ink droplet of 10.1pl.

[0060] 220. Determine the target nozzle corresponding to the unit to be printed based on the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle.

[0061] In some implementations, among multiple nozzles, the electronic device can select the nozzle whose first droplet volume is closest to a preset droplet volume as the target nozzle corresponding to the unit to be printed.

[0062] For example, if the preset droplet volume of the unit to be printed is 10.0 pl, the first droplet volume corresponding to one nozzle is 10.3 pl, and the first droplet volume corresponding to another nozzle is 9.9 pl, then the nozzle with the first droplet volume of 9.9 pl is selected as the target nozzle.

[0063] In some implementations, if the unit to be printed needs to use multiple target nozzles for inkjet printing, the nozzle whose first droplet volume is closest to the preset droplet volume can be selected as the target nozzle from all nozzles.

[0064] In some implementations, the electronic device may also acquire the number and size of the units to be printed in the panel to be printed; and determine the target nozzle corresponding to each unit to be printed based on the number and size of the units to be printed, as well as the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle.

[0065] For example, electronic devices can first determine the number of nozzles that can be evenly allocated to each printing unit among multiple nozzles based on the number of units to be printed.

[0066] Then, the electronic device determines the nozzle corresponding to each printing unit from among multiple nozzles based on the size of each unit and the corresponding preset ink droplet volume. For example, the larger the size of the printing unit and the larger the preset ink droplet volume of the printing unit, the larger the first ink droplet volume that the nozzle corresponding to the printing unit can actually fill.

[0067] In some implementations, the electronic device can input the number of printing units and the size of the printing units, the preset ink droplet volume corresponding to each printing unit, and the first ink droplet volume that each nozzle can actually fill as parameters into the inkjet printing system, and the inkjet printing system can then allocate nozzles to each printing unit to determine the target nozzle corresponding to the printing unit.

[0068] 230. Determine the total droplet volume based on the volume of the first droplet corresponding to the target nozzle.

[0069] After determining the target nozzles corresponding to the unit to be printed, the electronic device can determine the first droplet volume corresponding to each target nozzle, and then determine the total droplet volume based on the first droplet volumes corresponding to the target nozzles. For example, if the target nozzles corresponding to the unit to be printed are nozzle 3 and nozzle 2, and the first droplet volume corresponding to nozzle 3 is 10.3 pl, and the first droplet volume corresponding to nozzle 2 is 9.9 pl, then the total droplet volume is 20.2 pl.

[0070] In some implementations, the number of inkjet prints corresponding to each target nozzle can be obtained, and then the number of inkjet prints can be multiplied by the first ink droplet volume corresponding to the target nozzle to obtain the target first ink droplet volume. Finally, the target first ink droplet volumes are added together to obtain the total ink droplet volume.

[0071] For example, if nozzle 3 ejects ink twice, the target first ink droplet volume corresponding to nozzle 3 is 20.6 pl. If nozzle 2 ejects ink once, the target first ink droplet volume corresponding to nozzle 2 is 9.9 pl.

[0072] 240. If the total droplet volume does not meet the preset total droplet volume of the printing unit, determine the nozzle to be adjusted.

[0073] In some implementations, if the total droplet volume corresponding to the target nozzle is greater than or less than a preset total droplet volume, then the nozzle to be adjusted is identified among the target nozzles.

[0074] For example, if the total droplet volume is 30.5pl and the preset total droplet volume is 30pl, then the nozzle to be adjusted is determined in the target nozzle, and then the actual droplet volume of the nozzle to be adjusted is adjusted.

[0075] In some implementations, the electronic device can determine the difference between a preset total droplet volume and a total droplet volume, and then determine the nozzle to be adjusted in the target nozzle based on the difference.

[0076] Specifically, the electronic device can determine the adjustable volume range corresponding to each target nozzle; identify the target nozzles containing the difference within the adjustable volume range as nozzles to be selected; and identify the nozzle to be adjusted among the nozzles to be selected.

[0077] For example, if the fillable droplet volume range corresponding to target nozzle 1 is 9.7pl to 10.3pl, and the first droplet volume corresponding to target nozzle 1 under the first waveform is 10.0pl, then the adjustable range corresponding to target nozzle 1 is -0.3pl to 0pl and 0pl to 0.3pl. If the difference between the preset total droplet volume and the total droplet volume is within the range of -0.3pl to 0pl or 0pl to 0.3pl, then target nozzle 1 is the nozzle to be selected.

[0078] If there are multiple nozzles to be selected, the electronic device can randomly determine the nozzle to be adjusted from among them.

[0079] The electronic device can also determine the inkjet sequence of each nozzle to be selected; based on the inkjet sequence, the nozzle that last sprays ink is selected from among multiple nozzles to be selected as the nozzle to be adjusted. For example, if the target nozzle 1 is the last nozzle to spray ink among multiple nozzles to be selected, then target nozzle 1 can be selected as the nozzle to be adjusted.

[0080] If the printing unit requires multiple nozzles to be adjusted, the electronic device can determine the last few inkjet nozzles to be adjusted according to the required number of nozzles to be adjusted and the inkjet sequence.

[0081] In some implementations, if the adjustable volume range corresponding to each target nozzle does not include the difference, then multiple nozzles to be adjusted are determined in the target nozzles, and the sum of the adjustable volumes of each nozzle to be adjusted is equal to the difference.

[0082] If the adjustable volume range corresponding to each target nozzle does not include the difference, it means that a single target nozzle cannot meet the adjustment of the difference. In this case, multiple nozzles are needed to achieve the adjustment of the difference.

[0083] For example, the adjustable volume range of nozzle 1 to be adjusted is -0.3pl to 0pl or 0pl to 0.3pl, and the adjustable volume range of nozzle 2 to be adjusted is -0.2pl to 0pl or 0pl to 0.3pl. If the difference between the preset total ink droplet volume and the total ink droplet volume is -0.4pl, then the ink droplet volume in nozzles 1 and 2 to be adjusted needs to be reduced. In this case, the adjustment volume that nozzle 1 needs to reduce can be determined as -0.3pl, and the adjustment volume that nozzle 2 needs to reduce is determined as -0.1pl. Then the adjustment volume that nozzle 1 needs to reduce -0.3pl is in the range of -0.3pl to 0pl, and the adjustment volume that nozzle 2 needs to reduce -0.1pl is in the range of -0.2pl to 0pl.

[0084] The adjustment volume reduction required for nozzle 1 (-0.3pl) plus the adjustment volume reduction required for nozzle 2 (-0.1pl) equals the difference (-0.4pl).

[0085] In some implementations, the electronic device may also randomly select one or more target nozzles from a plurality of target nozzles as the nozzle to be adjusted.

[0086] 250. Adjust the first waveform corresponding to the nozzle to be adjusted to obtain the second waveform corresponding to the nozzle to be adjusted.

[0087] In some implementations, the waveform corresponding to the nozzle to be adjusted is a first waveform, which indicates that the volume of the first ink droplet filled by the nozzle to be adjusted is insufficient to meet the required volume of ink droplets to be ejected. Therefore, it is necessary to adjust the first waveform corresponding to the nozzle to be adjusted to obtain a second waveform corresponding to the nozzle to be adjusted.

[0088] In some implementations, the electronic device can determine the volume of the second ink droplet that the nozzle to be adjusted needs to fill, and then adjust the first waveform corresponding to the nozzle to be adjusted according to the volume of the second ink droplet to obtain the second waveform corresponding to the nozzle to be adjusted.

[0089] In some implementations, if the number of nozzles to be adjusted is one, the first ink droplet volume corresponding to the nozzle to be adjusted is added to or subtracted from the difference between the preset total ink droplet volume and the total ink droplet volume to obtain the second ink droplet volume that the nozzle to be adjusted needs to fill.

[0090] A positive difference between the preset total droplet volume and the preset total droplet volume indicates that the volume of ink droplets filling the nozzle to be adjusted needs to be increased. A negative difference between the preset total droplet volume and the total droplet volume indicates that the volume of ink droplets filling the nozzle to be adjusted needs to be decreased.

[0091] In some implementations, if there are multiple nozzles to be adjusted, the sum of the first ink droplet volumes corresponding to the multiple nozzles to be adjusted is determined; the sum of the first ink droplet volumes is added to or subtracted from the difference between the preset total ink droplet volume and the total ink droplet volume to obtain the target volume; the target volume is divided by the number of nozzles to be adjusted to obtain the second ink droplet volume that each nozzle to be adjusted needs to fill.

[0092] For example, if there are 3 nozzles to be adjusted, and the sum of the first ink droplet volumes corresponding to the nozzles to be adjusted is 29.7pl, and the difference between the preset total ink droplet volume and the total ink droplet volume is 0.3pl, then by adding the first ink droplet volume of 29.7pl to the difference of 0.3pl, we get 30pl. Then by dividing 30pl by 3, we get the second ink droplet volume that each nozzle to be adjusted needs to fill is 10pl.

[0093] The electronic device can modify the voltage parameters in the first waveform based on the volume of the second ink droplet to obtain the second waveform.

[0094] For example, combining Figure 2 The volume of the first ink droplet in the nozzle to be adjusted needs to be increased to obtain the actual volume of the second ink droplet that can be filled. The electronic device can control the CNC inverter 123 to reduce the output voltage, thereby controlling the small deformation of the piezoelectric ceramic plate 122, thereby increasing the fillable volume of the ink excitation chamber 121, and finally increasing the volume of the first ink droplet in the nozzle to be adjusted to obtain the volume of the second ink droplet. At this time, the electronic device can record the corresponding voltage parameters as parameters in the second waveform.

[0095] In some application scenarios, the preset total ink droplet volume is 30pl, the total ink droplet volume is 30.5pl, the target first ink droplet volume that nozzle 3 needs to spray is 20.6pl, and the first ink droplet volume corresponding to nozzle 2 is 9.9pl, then the ink droplet volume that nozzle 2 can spray needs to be adjusted to 9.4pl, that is, the second ink droplet volume.

[0096] Then, the first waveform corresponding to nozzle 2 is adjusted according to the second ink droplet volume of 9.4pl to obtain the second waveform, so that the electronic device can control nozzle 2 to eject ink of the second ink droplet volume according to the second waveform.

[0097] 260. Perform inkjet printing on the unit to be printed according to the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted.

[0098] In some implementations, after obtaining the second waveform corresponding to the nozzle to be adjusted, inkjet printing can be performed based on the target nozzle and the nozzle to be adjusted corresponding to the printing unit. The target nozzle uses a first waveform, while the nozzle to be adjusted uses a second waveform. By adjusting the first waveform of the nozzle to be adjusted, the nozzle to be adjusted can eject the required ink droplet volume according to the second waveform.

[0099] For example, if the preset total droplet volume required for the printing unit is 30pl, the target nozzle can eject droplets of 20.6pl, while the nozzle to be adjusted can eject droplets of 9.4pl through the second waveform, thus making the actual droplet volume in the printing unit 30pl, thereby reducing the difference between the actual droplet volume and the preset total droplet volume in the printing unit.

[0100] In this embodiment, the electronic device acquires the preset droplet volume of the unit to be printed and the first droplet volume of the nozzle corresponding to the first waveform; determines the target nozzle corresponding to the unit to be printed based on the preset droplet volume of the unit to be printed and the first droplet volume of the nozzle; then determines the total droplet volume based on the first droplet volume of the target nozzle; if the total droplet volume does not meet the preset total droplet volume of the unit to be printed, determines the nozzle to be adjusted; adjusts the first waveform corresponding to the nozzle to be adjusted to obtain the second waveform corresponding to the nozzle to be adjusted; finally, inkjet printing is performed on the unit to be printed based on the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted. This embodiment can reduce the difference between the total droplet volume ejected by the nozzle corresponding to the unit to be printed and the preset total droplet volume of the unit to be printed.

[0101] For a more detailed understanding of the inkjet printing method provided in the embodiments of this application, please refer to the following: Figure 5 , Figure 5This is a second flowchart illustrating the inkjet printing method provided in this application embodiment. The inkjet printing method may include the following steps:

[0102] 301. Drive the nozzle to fill with ink according to the first waveform, and determine the volume of the first ink droplet filled in the nozzle.

[0103] It should be noted that step 210 may include step 301.

[0104] In some implementations, the nozzle waveform is adjusted before inkjet printing. Once a set of waveform parameters is determined, the volume of the ejected ink droplets is fixed on the nozzle of the inkjet printhead.

[0105] Once the first waveform is determined, the electronic device can control multiple nozzles to draw ink based on the first waveform, and then the electronic device can determine the corresponding first ink droplet volume in each nozzle. Theoretically, the first ink droplet volume filled by the nozzle controlled by the first waveform should be equal to the preset ink droplet volume. However, in actual scenarios, the first ink droplet volume of some nozzles may differ from the preset ink droplet volume. For example, the ink droplet volume in the nozzle may be larger or smaller than the target ink droplet volume.

[0106] For example, if the preset droplet volume is 10.0 pl (picoliter), the actual volume of the first droplet filled in the nozzle is 10.1 pl, which is greater than the preset droplet volume.

[0107] In some implementations, the electronic device can acquire the volume of a first ink droplet within each nozzle, which is the actual volume of ink droplets drawn by the nozzle. For example, the first ink droplet volume corresponding to nozzle 1 is 10.1 pl, and the first ink droplet volume corresponding to nozzle 2 is 9.9 pl.

[0108] Since the first waveform corresponding to multiple nozzles is determined, the actual volume of the first ink droplet drawn into the nozzle is the volume of the ink droplets that will be ejected subsequently. For example, if the volume of the first ink droplet corresponding to nozzle 1 is 10.1pl, then nozzle 1 will subsequently eject an ink droplet of 10.1pl.

[0109] In some embodiments, after driving the nozzle to fill ink according to the first waveform and determining the volume of the first ink droplet filled in the nozzle, the electronic device can determine the ink parameters of the ink in the nozzle; establish a mapping relationship between the ink parameters and the first waveform, wherein the ink parameters include at least one of viscosity, surface tension parameter, and density.

[0110] When an electronic device needs to use ink for inkjet printing again, it can input the ink parameters and then match the first waveform corresponding to the nozzle in the mapping relationship based on the ink parameters.

[0111] 302. Determine the target nozzle corresponding to the unit to be printed based on the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle.

[0112] It should be noted that step 220 includes step 302.

[0113] In some implementations, among multiple nozzles, the electronic device can select the nozzle whose first droplet volume is closest to a preset droplet volume as the target nozzle corresponding to the unit to be printed.

[0114] For example, if the preset droplet volume of the unit to be printed is 10.0 pl, the first droplet volume corresponding to one nozzle is 10.3 pl, and the first droplet volume corresponding to another nozzle is 9.9 pl, then the nozzle with the first droplet volume of 9.9 pl is selected as the target nozzle.

[0115] In some implementations, if the unit to be printed needs to use multiple target nozzles for inkjet printing, the nozzle whose first droplet volume is closest to the preset droplet volume can be selected as the target nozzle from all nozzles.

[0116] In some implementations, the electronic device may also acquire the number and size of the units to be printed in the panel to be printed; and determine the target nozzle corresponding to each unit to be printed based on the number and size of the units to be printed, as well as the preset ink droplet volume of the unit to be printed and the first ink droplet volume corresponding to the nozzle.

[0117] For example, electronic devices can first determine the number of nozzles that can be evenly allocated to each printing unit among multiple nozzles based on the number of units to be printed.

[0118] Then, the electronic device determines the nozzle corresponding to each printing unit from among multiple nozzles based on the size of each unit and the corresponding preset ink droplet volume. For example, the larger the size of the printing unit and the larger the preset ink droplet volume of the printing unit, the larger the first ink droplet volume that the nozzle corresponding to the printing unit can actually fill.

[0119] In some implementations, the electronic device can input the number of printing units and the size of the printing units, the preset ink droplet volume corresponding to each printing unit, and the first ink droplet volume that each nozzle can actually fill as parameters into the inkjet printing system, and the inkjet printing system can then allocate nozzles to each printing unit to determine the target nozzle corresponding to the printing unit.

[0120] 303. Determine the total ink droplet volume based on the volume of the first ink droplet corresponding to the target nozzle.

[0121] It should be noted that step 230 includes step 303.

[0122] After determining the target nozzles corresponding to the unit to be printed, the electronic device can determine the first droplet volume corresponding to each target nozzle, and then determine the total droplet volume based on the first droplet volumes corresponding to the target nozzles. For example, if the target nozzles corresponding to the unit to be printed are nozzle 3 and nozzle 2, and the first droplet volume corresponding to nozzle 3 is 10.3 pl, and the first droplet volume corresponding to nozzle 2 is 9.9 pl, then the total droplet volume is 20.2 pl.

[0123] In some implementations, the number of inkjet prints corresponding to each target nozzle can be obtained, and then the number of inkjet prints can be multiplied by the first ink droplet volume corresponding to the target nozzle to obtain the target first ink droplet volume. Finally, the target first ink droplet volumes are added together to obtain the total ink droplet volume.

[0124] For example, if nozzle 3 ejects ink twice, the target first ink droplet volume corresponding to nozzle 3 is 20.6 pl. If nozzle 2 ejects ink once, the target first ink droplet volume corresponding to nozzle 2 is 9.9 pl.

[0125] 304. Determine the difference between the preset total ink droplet volume and the total ink droplet volume.

[0126] It should be noted that step 240 may include steps 304 to 306.

[0127] For example, if the preset total ink droplet volume is 30pl, and the target nozzles for the printing unit are nozzle 3 and nozzle 2, with the first ink droplet volume corresponding to nozzle 3 being 10.3pl and the first ink droplet volume corresponding to nozzle 2 being 9.9pl, and nozzle 3 sprays ink twice while nozzle 2 sprays ink once, then the total ink droplet volume is 30.5pl.

[0128] The preset difference between the total ink droplet volume and the total ink droplet volume is -0.5pl.

[0129] 305. Determine the adjustable volume range corresponding to each target nozzle.

[0130] For example, if the fillable droplet volume range corresponding to target nozzle 1 is 9.7pl to 10.3pl, and the first droplet volume corresponding to target nozzle 1 under the first waveform is 10.0pl, then the adjustable range corresponding to target nozzle 1 is -0.3pl to 0pl and 0pl to 0.3pl.

[0131] 306. Based on the difference and the adjustable volume range, determine the nozzle to be adjusted in the target nozzle.

[0132] Specifically, the electronic device can identify target nozzles containing differences within the adjustable volume range as nozzles to be selected; and identify the nozzle to be adjusted from among the nozzles to be selected.

[0133] For example, the adjustable range corresponding to the target nozzle 1 is -0.3pl to 0pl and 0pl to 0.3pl. If the difference between the preset total ink droplet volume and the total ink droplet volume is -0.2pl, then -0.2pl is within the range of -0.3pl to 0pl or 0pl to 0.3pl, indicating that the target nozzle 1 is the nozzle to be selected.

[0134] The electronic device can also determine the inkjet sequence of each nozzle to be selected; based on the inkjet sequence, the nozzle that last sprays ink is selected from among multiple nozzles to be selected as the nozzle to be adjusted. For example, if the target nozzle 1 is the last nozzle to spray ink among multiple nozzles to be selected, then target nozzle 1 can be selected as the nozzle to be adjusted.

[0135] If the printing unit requires multiple nozzles to be adjusted, the electronic device can determine the last few inkjet nozzles to be adjusted according to the required number of nozzles to be adjusted and the inkjet sequence.

[0136] In some implementations, if the adjustable volume range corresponding to each target nozzle does not include the difference, then multiple nozzles to be adjusted are determined in the target nozzles, and the sum of the adjustable volumes of each nozzle to be adjusted is equal to the difference.

[0137] If the adjustable volume range corresponding to each target nozzle does not include the difference, it means that a single target nozzle cannot meet the adjustment of the difference. In this case, multiple nozzles are needed to achieve the adjustment of the difference.

[0138] For example, the adjustable volume range of nozzle 1 to be adjusted is -0.3pl to 0pl or 0pl to 0.3pl, and the adjustable volume range of nozzle 2 to be adjusted is -0.2pl to 0pl or 0pl to 0.3pl. If the difference between the preset total ink droplet volume and the total ink droplet volume is -0.4pl, then the ink droplet volume in nozzles 1 and 2 to be adjusted needs to be reduced. In this case, the adjustment volume that nozzle 1 needs to reduce can be determined as -0.3pl, and the adjustment volume that nozzle 2 needs to reduce is determined as -0.1pl. Then the adjustment volume that nozzle 1 needs to reduce -0.3pl is in the range of -0.3pl to 0pl, and the adjustment volume that nozzle 2 needs to reduce -0.1pl is in the range of -0.2pl to 0pl.

[0139] The adjustment volume reduction required for nozzle 1 (-0.3pl) plus the adjustment volume reduction required for nozzle 2 (-0.1pl) equals the difference (-0.4pl).

[0140] 307. Determine the second droplet volume that the nozzle to be adjusted needs to fill based on the difference between the first droplet volume corresponding to the nozzle to be adjusted and the total droplet volume and the preset total droplet volume.

[0141] It should be noted that step 250 includes steps 307 and 308.

[0142] In some implementations, if the number of nozzles to be adjusted is one, the first ink droplet volume corresponding to the nozzle to be adjusted is added to or subtracted from the difference between the preset total ink droplet volume and the total ink droplet volume to obtain the second ink droplet volume that the nozzle to be adjusted needs to fill.

[0143] For example, if the volume of the first ink droplet of the nozzle to be adjusted is 9.8pl, and the difference between the preset total ink droplet volume and the total ink droplet volume is 0.2pl, then the volume of the first ink droplet plus the difference will give the volume of the second ink droplet as 10pl.

[0144] In some implementations, if there are multiple nozzles to be adjusted, the sum of the first ink droplet volumes corresponding to the multiple nozzles to be adjusted is determined; the sum of the first ink droplet volumes is added to or subtracted from the difference between the preset total ink droplet volume and the total ink droplet volume to obtain the target volume; the target volume is divided by the number of nozzles to be adjusted to obtain the second ink droplet volume that each nozzle to be adjusted needs to fill.

[0145] For example, if there are 3 nozzles to be adjusted, and the sum of the first ink droplet volumes corresponding to the nozzles to be adjusted is 29.7pl, and the difference between the preset total ink droplet volume and the total ink droplet volume is 0.3pl, then by adding the first ink droplet volume of 29.7pl to the difference of 0.3pl, we get 30pl. Then by dividing 30pl by 3, we get the second ink droplet volume that each nozzle to be adjusted needs to fill is 10pl.

[0146] 308. Adjust the first waveform corresponding to the nozzle to be adjusted according to the volume of the second ink droplet to obtain the second waveform corresponding to the nozzle to be adjusted.

[0147] The electronic device can modify the voltage parameters in the first waveform based on the volume of the second ink droplet to obtain the second waveform.

[0148] For example, combining Figure 2 The volume of the first ink droplet in the nozzle to be adjusted needs to be increased to obtain the actual volume of the second ink droplet that can be filled. The electronic device can reduce the output voltage by controlling the CNC inverter 123, thereby controlling the small deformation of the piezoelectric ceramic plate 122, thereby increasing the fillable volume of the ink excitation chamber 121, and finally increasing the volume of the first ink droplet in the nozzle to be adjusted to obtain the volume of the second ink droplet. At this time, the electronic device can record the corresponding voltage parameters as parameters in the second waveform.

[0149] In some application scenarios, the preset total ink droplet volume is 30pl, the total ink droplet volume is 30.5pl, the target first ink droplet volume that nozzle 3 needs to spray is 20.6pl, and the first ink droplet volume corresponding to nozzle 2 is 9.9pl, then the ink droplet volume that nozzle 2 can spray needs to be adjusted to 9.4pl, that is, the second ink droplet volume.

[0150] Then, the first waveform corresponding to nozzle 2 is adjusted according to the second ink droplet volume of 9.4pl to obtain the second waveform, so that the electronic device can control nozzle 2 to eject ink of the second ink droplet volume according to the second waveform.

[0151] 309. Perform inkjet printing on the unit to be printed according to the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted.

[0152] It should be noted that step 260 includes step 309.

[0153] In some implementations, after obtaining the second waveform corresponding to the nozzle to be adjusted, inkjet printing can be performed based on the target nozzle and the nozzle to be adjusted corresponding to the printing unit. The target nozzle uses a first waveform, while the nozzle to be adjusted uses a second waveform. By adjusting the first waveform of the nozzle to be adjusted, the nozzle to be adjusted can eject the required ink droplet volume according to the second waveform.

[0154] For example, if the preset total droplet volume required for the printing unit is 30pl, the target nozzle can eject droplets of 20.6pl, while the nozzle to be adjusted can eject droplets of 9.4pl through the second waveform, thus making the actual droplet volume in the printing unit 30pl, thereby reducing the difference between the actual total droplet volume and the preset total droplet volume in the printing unit.

[0155] In this embodiment, the electronic device drives the nozzle to fill with ink according to a first waveform and determines the first droplet volume of the ink filled in the nozzle. Based on the preset droplet volume of the unit to be printed and the first droplet volume corresponding to the nozzle, the target nozzle corresponding to the unit to be printed is determined. Then, the total droplet volume is determined based on the first droplet volume corresponding to the target nozzle, and the difference between the preset total droplet volume and the total droplet volume is determined to determine the adjustable volume range corresponding to each target nozzle.

[0156] Next, based on the difference and the adjustable volume range, the nozzle to be adjusted is determined in the target nozzle. Based on the difference between the first droplet volume corresponding to the nozzle to be adjusted and the total droplet volume, and the preset total droplet volume, the second droplet volume that the nozzle to be adjusted needs to fill is determined. The first waveform corresponding to the nozzle to be adjusted is then adjusted according to the second droplet volume to obtain the second waveform corresponding to the nozzle to be adjusted. Finally, inkjet printing is performed on the printing unit based on the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted. This ensures that the total droplet volume ejected by the nozzle corresponding to the printing unit is equal to the preset total droplet volume of the printing unit.

[0157] For a more detailed understanding of the inkjet printing method provided in the embodiments of this application, please refer to [link / reference]. Figure 6 , Figure 6 This is a schematic diagram of an inkjet printing scenario provided in an embodiment of this application.

[0158] like Figure 6 As shown, the unit to be printed can be a target pixel, which is X. Nozzle 1 is P1, nozzle 2 is P2, and nozzle 3 is P3. The droplet volume corresponding to each nozzle ranges from 9.7pl to 10.3pl.

[0159] The target nozzles corresponding to the target pixel are nozzle 2 and nozzle 3, and the preset total ink droplet volume to be filled by the target pixel is 30pl.

[0160] After being driven by the first waveform, nozzle 3 can pick up a first ink droplet with a volume of 10.3 pl, and nozzle 2 can pick up a first ink droplet with a volume of 9.9 pl.

[0161] Nozzle 3 ejects two ink drops in succession, that is... Figure 6 If we consider ink droplets S1 and S2, then the actual ink droplet volume filling the target pixel is 20.6pl. Subtracting the actual ink droplet volume from the preset total ink droplet volume, we find that a second ink droplet volume of 9.4pl is still needed.

[0162] The electronic device identifies nozzle 2 as the nozzle to be adjusted, and then adjusts the first waveform of nozzle 2 to obtain a second waveform. This second waveform drives nozzle 2 to draw in a 9.4pl volume ink droplet. Nozzle 2 can then eject a 9.4pl volume ink droplet into the target pixel.

[0163] By using the above method, the total volume of ink actually ejected by the nozzle corresponding to the target pixel can be equal to the preset total volume of ink droplets corresponding to the target pixel. This results in a more uniform image display when the display panel is in production.

[0164] Please see Figure 7 , Figure 7This is a schematic diagram of the structure of the inkjet printing apparatus provided in the embodiments of this application. The inkjet printing apparatus 400 may include:

[0165] The acquisition module 410 is used to acquire the preset ink droplet volume of the unit to be printed and the first ink droplet volume of the nozzle under the first waveform.

[0183] The adjustment module 450 is also used to determine the second ink drop volume that the nozzle to be adjusted needs to fill based on the first ink drop volume corresponding to the nozzle to be adjusted and the difference between the preset total ink drop volume and the total ink drop volume;

[0184] The first waveform corresponding to the nozzle to be adjusted is obtained by adjusting the second waveform based on the volume of the second ink droplet.

[0185] The adjustment module 450 is also used to, if the number of nozzles to be adjusted is one, add or subtract the difference between the preset total ink drop volume and the total ink drop volume corresponding to the first ink drop volume of the nozzle to be adjusted, so as to obtain the second ink drop volume that the nozzle to be adjusted needs to fill.

[0186] The adjustment module 450 is also used to determine the sum of the volumes of the first ink droplets corresponding to the multiple nozzles to be adjusted if there are multiple nozzles to be adjusted.

[0187] The target volume is obtained by adding or subtracting the difference between the preset total ink drop volume and the total ink drop volume from the sum of the volumes of the first ink droplets.

[0188] Divide the target volume by the number of nozzles to be adjusted to obtain the second droplet volume that each nozzle to be adjusted needs to fill.

[0189] The printing module 460 is used to perform inkjet printing on the unit to be printed according to the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted.

[0190] In this embodiment, the electronic device acquires the preset droplet volume of the unit to be printed and the first droplet volume of the nozzle corresponding to the first waveform; determines the target nozzle corresponding to the unit to be printed based on the preset droplet volume of the unit to be printed and the first droplet volume of the nozzle; then determines the total droplet volume based on the first droplet volume of the target nozzle; if the total droplet volume does not meet the preset total droplet volume of the unit to be printed, determines the nozzle to be adjusted; adjusts the first waveform corresponding to the nozzle to be adjusted to obtain the second waveform corresponding to the nozzle to be adjusted; finally, inkjet printing is performed on the unit to be printed based on the first waveform corresponding to the target nozzle and the second waveform corresponding to the nozzle to be adjusted. This embodiment can reduce the difference between the total droplet volume ejected by the nozzle corresponding to the unit to be printed and the preset total droplet volume of the unit to be printed.

Those skilled in the art will understand that... Figure 8 The electronic device structure shown does not constitute a limitation on the electronic device and may include more or fewer components than shown, or combine certain components, or have different component arrangements. Wherein:

[0192] The memory 501 can be used to store software programs and modules.

The program storage area may store the operating system, application programs required for at least one function (such as sound playback function, image playback function, etc.), etc.; the data storage area may store data created according to the use of the electronic device (such as audio data, telephone directory, etc.). In addition, the memory 501 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, the memory 501 may also include a memory controller to provide access to the memory 501 for the processor 505 and the input unit 502.

Specifically, in one embodiment, input unit 502 may include a touch-sensitive surface and other input devices. A touch-sensitive surface, also known as a touch display or touchpad, can collect user touch operations on or near it (e.g., user operations using fingers, styluses, or any suitable object or accessory on or near the touch-sensitive surface) and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, transmitting the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to the processor 505, and can receive and execute commands from the processor 505. Furthermore, various types of touch-sensitive surfaces, such as resistive, capacitive, infrared, and surface acoustic wave, can be used. In addition to the touch-sensitive surface, input unit 502 may also include other input devices. Specifically, other input devices may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

Display unit 503 may include a display panel, optionally configured as a liquid crystal display (LCD), organic light-emitting diode (OLED), or similar form. Furthermore, a touch-sensitive surface may cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it transmits the information to processor 505 to determine the type of touch event. Subsequently, processor 505 provides corresponding visual output on the display panel according to the type of touch event. Although in Figure 8 In this context, the touch-sensitive surface and the display panel are two separate components for implementing input and output functions.

As a type of motion sensor, a gravity acceleration sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that identify the posture of electronic devices (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition-related functions (such as pedometers, taps), etc. Other sensors that may be configured in electronic devices, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

By running or executing software programs and / or modules stored in memory 501, and by calling data stored in memory 501, it performs various functions and processes data, thereby providing overall monitoring of the electronic device. Optionally, processor 505 may include one or more processing cores; preferably, processor 505 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 505.

[0197] The electronic device also includes a power supply 506 (such as a battery) that supplies power to various components. Preferably, the power supply can be logically connected to the processor 505 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply 506 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.
