Description

Technical Field

[0001] This application relates to the field of inkjet printer technology for displays, specifically to a method for processing seam mura patterns and an inkjet printer. Background Technology

[0002] Currently, in inkjet printing (piezoelectric or electro-hydraulic), when the substrate size to be printed is larger than the printhead module's printing size, the printhead module performs multiple print passes. That is, the printhead module needs to perform multiple passes to print the entire substrate; therefore, a one-pass printing method cannot be used.

[0003] However, because two adjacent passes cannot achieve a perfect fit; or rather, at the seam between two adjacent passes, the ink droplet thickness is uneven, resulting in visible Mura patterns. For example... Figure 1 As shown, the X direction is the travel direction of the nozzle module 101, and the Y direction is the travel direction of the substrate 100. The nozzle module 101 is in... Figure 1 The first print of a, with printhead module 101 in Figure 1 The second print in step b will create seam 102. When the seam between the two prints is narrow, the ink droplet thickness at the seam increases, producing a Mura pattern; when the seam between the two prints is wide, the ink droplet thickness at the seam decreases, producing a Mura pattern. Mura patterns (both raised and recessed) affect print quality and also the display quality of the OLED display panel.

[0004] Therefore, how to reduce the Mura pattern between two adjacent passes has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a method for processing seam murmurs and an inkjet printer, which can reduce seam murmurs between two adjacent passes.

[0006] The first aspect of this application discloses a method for processing seam Mura patterns, the method comprising: dividing a pattern to be printed into at least two partitioned patterns; wherein, one partitioned pattern is a pattern printed by a printhead module on a substrate in a single operation, and the at least two partitioned patterns include a first partitioned pattern and a second partitioned pattern; performing a printing operation on the pattern to be printed using the first partitioned pattern and the second partitioned pattern; wherein the first partitioned pattern is the pattern printed by the printhead module on the substrate for the first time, and the second partitioned pattern is the pattern printed by the printhead module on the substrate for the second time.

[0007] In the above scheme, the seam mura pattern between two adjacent passes is "blurred" by setting a partition pattern; the partition pattern makes the seam between two adjacent passes no longer a straight line, thereby reducing the seam mura pattern between two adjacent passes.

[0008] In one possible implementation, after performing the printing operation of the pattern to be printed, the method further includes: obtaining the film thickness of the edge region and determining whether the film thickness is within a preset film thickness range; the edge region is the adjacent region of the first partition pattern and the second partition pattern; if the film thickness of the edge region is within the preset film thickness range, then the film printing of the edge region is confirmed to be qualified.

[0009] In the above scheme, an edge region is set. Within the edge region, the two partition patterns may or may not overlap. In scenarios where there is a further requirement for the film thickness in the edge region, the film thickness range can be set to determine whether the film printing is qualified. If the film printing in the edge region is qualified, it means that not only is the Mura pattern between two adjacent passes reduced, but the film thickness can also be further adjusted.

[0010] In one possible implementation, after determining whether the film thickness is within a preset film thickness range, the method further includes: if the film thickness of the edge region is outside the preset film thickness range, then confirming that the film printing of the edge region is unqualified; replacing the first partition pattern and the second partition pattern, and repeating the printing operation on the substrate until the film thickness printed in the edge region is qualified; wherein, replacing the first partition pattern and the second partition pattern specifically includes replacing the first partition pattern with a third partition pattern and replacing the second partition pattern with a fourth partition pattern.

[0011] The above solution provides a method to address the issue of substandard film thickness in edge regions. Since the film thickness is determined by the required range, a narrow range can lead to substandard thickness even after setting a partitioning pattern. In this case, a new partitioning pattern can be set to replace the previous one to resolve the problem.

[0012] In one possible implementation, before obtaining the film thickness of the edge region, the method further includes: printing a first edge region at a first ratio and printing a second edge region at a second ratio; wherein the edge region includes the first edge region and the second edge region, the first ratio is the proportion of ink droplets printed by the printhead module in the first printing phase to the printable landing area on the edge region, and the second ratio is the proportion of ink droplets printed by the printhead module in the second printing phase to the printable landing area on the edge region.

[0013] In the above solution, based on setting the edge area, the proportion of ink droplets falling during inkjet printing is adjusted to further reduce the seam mura pattern. By adjusting the proportion of ink droplets falling in the edge area, the film thickness in the edge area can be further adjusted, which can also further reduce the seam mura pattern.

[0014] In one possible implementation, the ratio of the first ratio to the second ratio ranges from 10% to 90%, and the sum of the first ratio and the second ratio ranges from 80% to 120%.

[0015] In the aforementioned implementation method that uses edge regions to calculate the droplet landing ratio, within the edge region, the first edge region is the landing region of the first partitioned pattern within the edge region, and the second edge region is the landing region of the second partitioned pattern within the edge region. However, the first edge region and the second edge region may or may not overlap. When they overlap, the first edge region and the second edge region may partially overlap or completely overlap (when they completely overlap, the first edge region, the second edge region, and the edge region are of equal size and constitute the same region). This solution limits the droplet landing ratio when the first edge region and the second edge region overlap, and this landing ratio is a preferred ratio that limits the film thickness of the edge region within a preset film thickness range.

[0016] In one possible implementation, before obtaining the film thickness of the edge region, the method further includes: printing a first edge region at a third ratio and printing a second edge region at a fourth ratio; wherein the edge region includes the first edge region and the second edge region, the third ratio is the proportion of the ink droplets printed by the printhead module in the first edge region to the printing landing area, and the fourth ratio is the proportion of the ink droplets printed by the printhead module in the second edge region to the printing landing area.

[0017] In the above solution, based on setting the edge pattern, the ink droplet landing ratio of inkjet printing is set to further reduce the seam mura pattern. Unlike the previous solution, this embodiment calculates the landing ratio based on the first edge area of ​​the printhead module, instead of using the edge area as in the previous solution; these two different setting methods make the landing ratio setting more flexible and can be selected according to actual needs.

[0018] In one possible implementation, the ratio range of the third ratio and the fourth ratio includes 10%-90%.

[0019] At this point, the implementation methods corresponding to the third and fourth ratios are to calculate the landing point ratio based on the first edge region. In the implementation method of calculating the landing ratio based on the first edge region, the first edge region and the second edge region may not overlap, may overlap partially, or may overlap completely. The preferred ratio ranges for the third and fourth ratios are as follows: When the first edge region and the second edge region do not overlap, the sum of the third and fourth ratios is preferably constrained to 100%-200%.

[0020] In one possible implementation, the at least two partition patterns further include other partition patterns that form multiple edge regions; wherein any two edge regions may use the same or different patterns.

[0021] In the above solution, the case of large-size substrates is considered; when the printhead module requires multiple passes for printing, there will be multiple edge regions. The patterns used for any two edge regions can be the same or different, which can be selected during the actual inkjet printing process.

[0022] In one possible implementation, the pattern to be printed is divided into at least two partitioned patterns, specifically including: obtaining the size of the substrate to be printed and the single-print size of the printhead module; and dividing the pattern to be printed into at least two partitioned patterns according to the substrate size and the single-print size.

[0023] The above scheme explains the basis for dividing the partitioned pattern. Of course, this is conditional, as the size of the substrate must be larger than the size of a single print.

[0024] In one possible implementation, the pattern shape of the edge region includes curved and straight lines.

[0025] The above scheme discloses two preferred edge region patterns. Compared with other edge region patterns, these two patterns can further reduce seam murmur.

[0026] A second aspect of this application discloses an inkjet printer, which includes a processor, a memory, a display, and a network interface. The memory is used to store instructions, and both the display and the network interface are used to communicate with other devices. The processor is used to execute the instructions stored in the memory to cause the inkjet printer to perform the following operations:

[0027] The pattern to be printed is divided into at least two partition patterns; wherein, one partition pattern is the pattern that the printhead module prints on the substrate in a single operation, and the at least two partition patterns include a first partition pattern and a second partition pattern.

[0028] The printing operation of the pattern to be printed is performed using the first partition pattern and the second partition pattern; the first partition pattern is the pattern printed by the printhead module on the substrate for the first time, and the second partition pattern is the pattern printed by the printhead module on the substrate for the second time.

[0029] A third aspect of this application provides an electronic device including a processor, a memory, a display, and a network interface, wherein the memory is used to store instructions, the display and the network interface are both used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the electronic device to perform the method as described in any of the foregoing.

[0030] A fourth aspect of this application provides a computer-readable storage medium storing instructions that, when executed, perform the method described in any of the preceding descriptions.

[0031] This application can reduce the Mura pattern at the seam between two adjacent passes. Attached Figure Description

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification 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.

Rather, the use of the words "for example" or "for instance" is intended to present the relevant concepts in a specific manner.

[0043] In the description of the embodiments of this application, the term "multiple" means two or more. For example, multiple systems means two or more systems, and multiple screen terminals means two or more screen terminals. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0044] This manual describes an inkjet printer, which can use either a piezoelectric or electrothermal printhead. In practice, the size of the substrate may differ from the size of the printhead module, necessitating pattern planning. The printhead module then performs multiple passes to complete the printing process. To address the issue of mura patterns forming at the edges of the two prints, this manual employs a pattern planning approach, focusing particularly on the edges of the two printed patterns.

[0045] This specification discloses a method for processing seam Mura patterns, such as... Figure 3 As shown. The method includes steps S110-S120.

[0046] Step S110: Divide the pattern to be printed into at least two partition patterns; wherein, one partition pattern is the pattern that the printhead module prints on the substrate in a single operation, and the at least two partition patterns include a first partition pattern and a second partition pattern.

[0047] Step S120: Using the first partition pattern and the second partition pattern, perform the printing operation of the pattern to be printed; the first partition pattern is the pattern printed on the substrate by the printhead module for the first time, and the second partition pattern is the pattern printed on the substrate by the printhead module for the second time.

[0048] The following explains how to set the partition pattern.

[0049] by Figure 4A As an example, edge region 201 is an adjacent region of the first partition pattern and the second partition pattern. The first partition pattern and the second partition pattern in the edge region may or may not overlap. Taking non-overlapping patterns as an example, such as... Figure 4A ; Figure 4A The image shows two printing patterns of the printhead module in the edge region 201. Pattern A is the first printing pattern of the printhead module in the edge region, and pattern B is the second printing pattern of the printhead module in the edge region. Figure 4A In the edge regions 201 of a, b, and c, the edge lines 202 of patterns A and B are different; in a, the edge line is a curve with less undulation; in b, the edge line is an irregular zigzag shape; and in c, the edge line is a curve with greater undulation. Regardless of the type of edge line, it is more... Figure 1 The thickness of the film layer printed by the 102 center seam should be uniform to reduce [the risk of defects]. Figure 1 The Mura pattern is visible to the naked eye at 102 seams in the middle.

[0050] In one example, the pattern shapes of the edge areas include curved and straight lines.

[0051] by Figure 4B For example, the pattern shapes of the edge areas are illustrated as curved and straight lines. Figure 4B Two preferred edge region patterns are shown, but the pattern is not limited to these. Figure 4A The shape of the pattern shown also meets the requirements; therefore, this application does not limit the shape of the pattern.

[0052] This instruction manual is Figure 4B Taking the pattern in the image as an example, we will further explain the characteristics of the pattern. Figure 4B The edge region pattern of pattern a is curved, and both pattern A and pattern B are patterns with curved edges. Figure 4BIn pattern b, the edge area pattern is linear. Patterns A and B are staggered, and both have straight edges. In pattern a, the frequency, period, and amplitude of the sine wave (a type of curve) are not limited; in actual use, testing will be conducted based on specific needs to ensure a more uniform film thickness. Similarly, for pattern b, printing in sections using patterns A and B also results in a more uniform film thickness; and the dimensions of patterns A and B are not limited, but can be adjusted after testing based on actual needs.

[0053] It should be noted that the above solution can reduce the murmur between two passes. This specification also discloses a further implementation scheme, namely, a further implementation scheme in inkjet printing that not only solves the problem of murmur between passes, but also has requirements on the film thickness range in the edge area.

[0054] In one example, after performing the printing operation of the pattern to be printed, the method further includes: obtaining the film thickness of the edge region and determining whether the film thickness is within the preset film thickness range; the edge region is the adjacent region of the first partition pattern and the second partition pattern; if the film thickness of the edge region is within the preset film thickness range, then the film printing of the edge region is confirmed to be qualified.

[0055] At this point, the film thickness range is set as needed. It should be noted that the film thickness in the edge region being outside the specified range does not mean that the problem of reducing seam mura is not addressed; that is, whether the film thickness in the edge region is within or outside the specified range, it can reduce seam mura issues in the current two passes of printing. However, since different inkjet printing processes require different film thicknesses, in practice, the film thickness range will be set according to the required film thickness.

[0056] Furthermore, when the film thickness in the edge region is outside the film thickness range, the film thickness problem can be alleviated by resetting the partition pattern.

[0057] In one example, after determining whether the film thickness is within the preset film thickness range, the method further includes: if the film thickness of the edge region is outside the preset film thickness range, then confirming that the film printing of the edge region is unqualified; replacing the first partition pattern and the second partition pattern, and repeating the printing operation on the substrate until the film thickness printed in the edge region is qualified; wherein, replacing the first partition pattern and the second partition pattern specifically includes replacing the first partition pattern with the third partition pattern and replacing the second partition pattern with the fourth partition pattern.

[0058] In this example, by setting a new partition pattern, the problem of the film thickness being outside the preset film thickness range can be solved. Just as the first and second partition patterns were not limited above, this specification also does not limit the specific patterns of the third and fourth partition patterns.

[0059] Furthermore, this manual allows for further adjustment of the film thickness in the edge region by adjusting the proportion of inkjet module landing points in the edge region each time.

[0060] In one example, before obtaining the film thickness of the edge region, the method further includes: printing a first edge region at a first ratio and printing a second edge region at a second ratio; wherein the edge region includes a first edge region and a second edge region, the first ratio being the proportion of ink droplets printed by the printhead module in the first printing to the printing landing area on the edge region, and the second ratio being the proportion of ink droplets printed by the printhead module in the second printing to the printing landing area on the edge region.

[0061] At this point, based on the established partition pattern, this application further reduces seam murmur by adjusting the ink droplet ratio during inkjet printing. By regulating the ink droplet ratio in the edge region, the film thickness in the edge region is further adjusted, thereby further reducing seam murmur.

[0062] Furthermore, within the edge region, the first edge region is the landing point of the first partition pattern within the edge region, and the second edge region is the landing point of the second partition pattern within the edge region; however, the first edge region and the second edge region may overlap or may not overlap; when they overlap, the first edge region and the second edge region may overlap partially or completely (when they overlap completely, the first edge region, the second edge region, and the edge region are of equal size and constitute the same region).

[0063] Figure 5A The example illustrates the case where patterns A and B do not overlap. Figure 5A Pattern A corresponds to the first edge region, and pattern B corresponds to the second edge region. Figure 5A exist Figure 4B Based on the selected pattern, an example is given of adjusting the proportion of ink droplets in the pattern to further control the film thickness in the edge area, making the film thickness in the edge area more uniform. Figure 5A In the diagram, a1 and a2 are both curved patterns. a1 is a schematic diagram of pattern A, and a2 is a schematic diagram of pattern B. The area to be printed, c2, is a magnified schematic diagram of a part of pattern B. The area to be printed, c2, shows a schematic diagram of the printing ink droplet occupying one-third of the local area to be printed. Figure 5AIn the diagram, b1 and b2 are both linear patterns. b1 is a schematic diagram of pattern A, and b2 is a schematic diagram of pattern B. The area to be printed, c1, is a magnified view of a portion of pattern A. The areas where ink droplets have already landed are 204, and the areas where ink droplets have not landed (non-droplet landing areas) are 203. c1 shows a schematic diagram of ink droplets occupying half of the area to be printed. The areas to be printed, c1 and c2, include both droplet landing areas and non-droplet landing areas. This specification does not limit the proportion of ink droplets in the area to be printed.

[0064] This specification also discloses the landing point ratio when the first edge region and the second edge region overlap (including partial overlap and complete overlap), which is a preferred ratio defining the edge region film thickness within a preset film thickness range. In one example, the ratio of the first ratio to the second ratio ranges from 10% to 90%, and the sum of the first ratio and the second ratio ranges from 80% to 120%.

[0065] also, Figure 5B The example shows a case where the two printed patterns completely overlap. Figure 5B In pattern a1, patterns A1 and A2 are both pattern A, and pattern B in a2 completely overlaps with pattern A2 in a1. In pattern b1, patterns A1 and A2 are both pattern A, and patterns B1 and B2 in b2 are both pattern B; pattern A1 in b1 overlaps with pattern B2 in b2; pattern A2 in b1 overlaps with pattern B1 in b2, meaning pattern A in b1 overlaps with pattern B in b2. Both of these pattern settings can reduce the seam Mura pattern between the two passes.

[0066] At this time, with Figure 5B Taking the sine wave (a type of curve, used as an example) patterns a1 and a2 as examples, patterns A1 and A2 in a1 serve as the printing landing points of the first edge region; the entire area of ​​pattern A1 can be printed, and 30% of pattern A2 can be printed (the proportion of the printed ink droplets in the area of ​​pattern A2 to be printed is omitted below for ease of description). At this time, the proportion of the printed ink droplets in pattern A to the printing landing points of the first edge region is 80%; pattern B in a2 is the printing landing point of the second edge region; the proportion of the printed ink droplets in pattern B to the printing landing points of the second edge region is 70%. Figure 5B Taking histogram patterns b1 and b2 as examples, patterns A1 and A2 in b1 correspond to the printing points of the first edge region, and patterns B1 and B2 in b2 correspond to the printing points of the second edge region. When A1 in b1 and B2 in b2 overlap, pattern A1 prints 70% of the overlapping area, and pattern B2 prints 30% of the overlapping area. When A2 in b1 and B1 in b2 overlap, pattern A2 prints 20% of the overlapping area, and pattern B1 prints 80% of the overlapping area.

[0067] In one example, before obtaining the film thickness of the edge region, the method further includes: printing the first edge region at a third ratio and printing the second edge region at a fourth ratio; wherein the edge region includes the first edge region and the second edge region, the third ratio is the proportion of the ink droplets printed by the printhead module in the first edge region to the printing landing area, and the fourth ratio is the proportion of the ink droplets printed by the printhead module in the second edge region to the printing landing area.

[0068] In one example, the proportions for both the third and fourth proportions range from 10% to 90%.

[0069] At this point, the implementation methods corresponding to the third and fourth ratios are to calculate the landing point ratio based on the first edge region. In the implementation method of calculating the landing ratio based on the first edge region, the first edge region and the second edge region may not overlap, may overlap partially, or may overlap completely. The preferred ratio ranges for the third and fourth ratios are as follows: When the first edge region and the second edge region do not overlap, the sum of the third and fourth ratios is preferably constrained to 100%-200%.

[0070] In one example, at least two partition patterns also include other partition patterns that form multiple edge regions; wherein any two edge regions may use the same or different patterns.

[0071] like Figure 2 As shown, the substrate 100 may have multiple edge regions. Two edge regions, edge region 200 and edge region 300, are shown in the figure. In this specification, an edge region is a region formed by the adjacent edges of two partitioned patterns. Figure 2 Figure 4 shows examples of pattern shapes for the edge regions. It should be noted that the size of the edge regions is not unique and can be determined based on ink droplet characteristics (such as ink droplet flowability) and substrate parameters (such as substrate size or substrate surface adhesion). This specification does not impose any restrictions on this.

[0072] Regarding the criteria for dividing the pattern into partitions: In one example, the pattern to be printed is divided into at least two partitions, specifically including: obtaining the size of the substrate to be printed and the single print size of the printhead module; dividing the pattern to be printed into at least two partitions based on the substrate size and the single print size.

[0073] This application can reduce the seam murras between two adjacent passes by setting a partitioned pattern. At the same time, by setting an edge region and judging the film thickness of the edge region, the film thickness of the edge region can be further limited, thereby further reducing the seam murras between two adjacent passes. In addition, by limiting the landing point ratio of the pattern in the edge region, the seam murras between two adjacent passes can be further reduced by controlling the film thickness.

[0074] This specification also discloses an inkjet printer, which includes a processor, a memory, a display, and a network interface. The memory is used to store instructions, the display and the network interface are both used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the inkjet printer to perform the following operations:

[0075] The pattern to be printed is divided into at least two partition patterns; wherein, one partition pattern is the pattern that the printhead module prints on the substrate in a single operation, and the at least two partition patterns include a first partition pattern and a second partition pattern.

[0076] The printing operation of the pattern to be printed is performed using the first partition pattern and the second partition pattern; the first partition pattern is the pattern printed on the substrate by the printhead module for the first time, and the second partition pattern is the pattern printed on the substrate by the printhead module for the second time.

[0077] In one example, after performing the printing operation of the pattern to be printed, the method further includes: obtaining the film thickness of the edge region and determining whether the film thickness is within the preset film thickness range; the edge region is the adjacent region of the first partition pattern and the second partition pattern; if the film thickness of the edge region is within the preset film thickness range, then the film printing of the edge region is confirmed to be qualified.

[0078] In one example, after determining whether the film thickness is within the preset film thickness range, the method further includes: if the film thickness of the edge region is outside the preset film thickness range, then confirming that the film printing of the edge region is unqualified; replacing the first partition pattern and the second partition pattern, and repeating the printing operation on the substrate until the film thickness printed in the edge region is qualified; wherein, replacing the first partition pattern and the second partition pattern specifically includes replacing the first partition pattern with the third partition pattern and replacing the second partition pattern with the fourth partition pattern.

[0079] In one example, before obtaining the film thickness of the edge region, the method further includes: printing a first edge region at a first ratio and printing a second edge region at a second ratio; wherein the edge region includes a first edge region and a second edge region, the first ratio being the proportion of ink droplets printed by the printhead module in the first printing to the printable landing area on the edge region, and the second ratio being the proportion of ink droplets printed by the printhead module in the second printing to the printable landing area on the edge region.

[0080] In one example, the ratio of the first ratio to the second ratio ranges from 10% to 90%, and the sum of the first ratio and the second ratio ranges from 80% to 120%.

[0081] In one example, before obtaining the film thickness of the edge region, the method further includes: printing the first edge region at a third scale and printing the second edge region at a fourth scale; wherein,

[0082] The edge region includes a first edge region and a second edge region. The third ratio is the proportion of the ink droplets printed by the printhead module in the first edge region to the area to be printed on the first edge region. The fourth ratio is the proportion of the ink droplets printed by the printhead module in the second edge region to the area to be printed on the second edge region.

[0083] In one example, the proportions for the third and fourth ratios range from 10% to 90%.

[0084] In one example, at least two partition patterns also include other partition patterns that form multiple edge regions; wherein any two edge regions may use the same or different patterns.

[0085] In one example, the pattern to be printed is divided into at least two partitioned patterns, which specifically includes: obtaining the substrate size to be printed and the single print size of the print head module; and dividing the pattern to be printed into at least two partitioned patterns based on the substrate size and the single print size.

[0086] In one example, the pattern shapes of the edge areas include curved and straight lines.
