Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides an inkjet printing method which can solve the problem of low printing efficiency in the related art.
The embodiment of the application provides an inkjet printing method, which can be realized through steps 101-103 as shown in fig. 1, and specifically comprises the following steps:
step 101: and planning the ink drop point of the substrate to obtain the initial ink drop point in the substrate.
Wherein the initial ink drop points in the substrate are distributed in an array, and the initial ink drop points in the substrate represent ink drop point positions of the nozzle device to be printed. Referring to fig. 3, the initial ink drop points in the substrate are distributed in an array, including virtual and real coils.
In some embodiments, the pitch of two adjacent sub-pixel pits in the substrate is a multiple of the pitch of two adjacent original ink drop points; the width of the sub-pixel pits is greater than a preset multiple of the initial drop point diameter.
In some examples, the ink drop point of the substrate is planned to obtain an initial ink drop point in the substrate, and the planning may be performed according to at least one parameter of the size of the substrate, the width of the sub-pixel pits, the distance between two adjacent sub-pixel pits, the distance between the initial ink drop points, the target film thickness of the ink material, and the step value of the printing nozzle.
Step 102: and according to a target disabling algorithm, disabling a part of initial ink drop points in the substrate to determine a control instruction corresponding to each initial ink drop point in the substrate.
The target disabling algorithm characterizes control instructions corresponding to initial ink drop points in the substrate, namely, the target disabling algorithm can obtain which control instructions corresponding to the initial ink drop points in the substrate are nozzles for ejecting ink and which control instructions are nozzles for disabling; the disabling process refers to setting a control instruction corresponding to the initial ink drop point such that the nozzle is disabled. The control instruction corresponding to the initial ink drop point characterizes the control instruction required to be executed when the nozzle of the nozzle device scans to the initial ink drop point, and the control instruction comprises the ink jet of the nozzle or the disabling of the nozzle.
In some embodiments, the disabling process may be implemented by: sequentially sequencing the serial numbers of the initial ink drop points from small to large along the scanning direction of the printing nozzle, and sequentially sequencing the serial numbers of the initial ink drop points from small to large along the vertical direction of the scanning direction of the printing nozzle to obtain two-dimensional serial numbers of the initial ink drop points; the disabling process for the initial ink drop points in the substrate that do not belong to the sub-pixel pit area is: taking the serial number of the initial ink drop point in the y direction as a forbidden condition; the disabling process for the initial ink drop points in the substrate belonging to the sub-pixel pit area is as follows: and taking the serial number of the forbidden initial ink drop point in the two-dimensional direction as a forbidden condition.
In some examples, planning ink drop points of a substrate to obtain initial ink drop points in the substrate; according to a target disabling algorithm, disabling a portion of the initial ink drop points in the substrate may include: and setting initial control instructions corresponding to the initial ink drop points in the substrate as nozzle ink jet, and adjusting the initial control instructions corresponding to part of the initial ink drop points in the substrate from nozzle ink jet to nozzle disabled according to a target disabling algorithm so as to determine target control instructions.
In other examples, disabling a portion of the initial drop points in the substrate according to a target disabling algorithm may include: according to a target disabling algorithm, determining that a control instruction in a substrate is an initial ink drop point corresponding to ink jet of a nozzle and the control instruction is an initial ink drop point corresponding to the disabled nozzle; and setting control instructions corresponding to all initial ink drop points in the substrate according to the determined control instructions.
According to the embodiment of the application, the interval between the initial ink drop points in the sub-pixel pits is shortened by disabling part of the initial ink drop points initially planned in the substrate, so that the printing efficiency of the printing nozzle and even the whole printing system is improved.
In some embodiments, according to the target disabling algorithm, disabling a portion of the initial ink drop points in the substrate to determine a control instruction corresponding to each initial ink drop point in the substrate may be implemented by steps 1021-1022, see fig. 2, which specifically includes the following steps:
step 1021: and determining initial ink drop points which do not belong to the sub-pixel pit area in the substrate according to the positions of the sub-pixel pits in the substrate.
It should be noted that an organic light Emitting Diode (OLED, organicLight-Emitting Diode) display screen is composed of a pixel array, and each pixel is composed of red, green and blue 3-color sub-pixel pits. It will be appreciated that the sub-pixel pits in the substrate are in sub-pixel pit areas, while other positions are non-sub-pixel pit areas. The initial ink drop points belonging to the sub-pixel pit areas are that the whole initial ink drop points are in the sub-pixel pit areas. For example, see fig. 3, where part of the initial drop points on three sub-pixel pits are exemplarily given, the initial drop points 1,4 each belong to a non-sub-pixel pit area, i.e. not to a sub-pixel pit area; the original ink drop point 2,3 belongs to a sub-pixel pit area.
Step 1022: and setting a control instruction corresponding to the initial ink drop point which does not belong to the sub-pixel pit area in the substrate as the nozzle is disabled.
According to the embodiment of the application, the initial ink drop points which do not belong to the sub-pixel pit area in the substrate are forbidden, so that the interval of the finally planned initial ink drop points (namely, the control instruction is that the nozzle sprays ink) to be printed is reduced, for example, one nozzle of the printing nozzle scans one sub-pixel pit once to print a plurality of ink drops at one time, and the printing efficiency of the printing nozzle is improved.
In other embodiments, according to the target disabling algorithm, disabling a portion of the initial ink drop points in the substrate to determine a control instruction corresponding to each initial ink drop point in the substrate may be implemented through steps 1023-1024, see fig. 4, which specifically includes the following steps:
step 1023: and determining a sub-pixel pit area and a non-sub-pixel pit area in the substrate according to the positions of the sub-pixel pits in the substrate.
Step 1024: determining initial ink drop points in the sub-pixel pit areas without ink jet according to the film thickness of the ink material required in each sub-pixel pit;
step 1025: the control instructions corresponding to the initial ink drop points in the substrate in the non-sub-pixel pit area and the initial ink drop points in the sub-pixel pit area where the ink does not need to be ejected are set to be disabled.
In an actual inkjet printing scene, the film thickness requirement on the ink material is finer, and the control instructions of the initial ink drop points belonging to the sub-pixel pit area are all set to be inkjet by the nozzles, so that the problem that the film thickness of the printed sub-pixel pits does not belong to the value range of the target film thickness can be caused. According to the embodiment of the application, the initial ink drop point needing to be sprayed in the sub-pixel pit area can be determined through testing according to the film thickness of the ink material needed in each sub-pixel pit, and the control instruction corresponding to the initial ink drop point needing not to be sprayed is set as the disabled nozzle. Therefore, the embodiment of the application can adaptively adjust the initial ink drop point required to jet ink so that the ink material printed by the method meets the preset condition of the target film thickness, and on the basis of improving the printing efficiency, the initial ink drop point can be adjusted more conveniently and controllably, thereby printing the substrate of the ink material with the preset condition meeting the target film thickness more accurately, and improving the printing quality.
Step 103: and sending a control instruction to the spray head equipment to control the spray head equipment to print out the substrate with the ink material meeting the preset condition of the target film thickness. The preset condition of the target film thickness is that the film thickness of the ink material is in the range of the target film thickness.
In some embodiments, the target disabling algorithm may also be determined by steps 201-203 before disabling a portion of the initial drop points in the substrate according to the target disabling algorithm. The method comprises the following specific steps:
step 201: determining a control instruction corresponding to each initial ink drop point in the substrate according to a candidate disabling algorithm; and controlling the nozzle device to print the ink material in the substrate according to the control instruction.
Step 202: after printing is completed, it is detected whether the film thickness of the ink material in the substrate is within the range of the target film thickness.
Step 203: if yes, determining the candidate forbidden algorithm as a target forbidden algorithm; if not, the candidate disabling algorithm is adjusted.
In some examples, adjusting the candidate disabling algorithm may be accomplished by: when the film thickness of the ink material in the substrate exceeds the value range of the target film thickness, regulating a disabling instruction corresponding to part of initial ink drop points in the substrate from nozzle ink jetting to nozzle disabling; when the film thickness of the ink material in the substrate is lower than the value range of the target film thickness, the control instruction corresponding to part of initial ink drop points in the substrate is forbidden to be regulated by the nozzles to inkjet the nozzles.
Specifically, the scanning direction of the printing nozzle is taken as the x direction, the vertical direction of the scanning direction of the printing nozzle is taken as the y direction, the serial numbers of the x direction of the initial ink drop points are sequentially ordered from small to large along the x direction, and the serial numbers of the y direction of the initial ink drop points are sequentially ordered from small to large along the y direction, namely, the two-dimensional serial numbers of the initial ink drop points can be obtained. Therefore, the disabling processing mode of the initial ink drop points which do not belong to the sub-pixel pit area in the substrate is only required to take the y-direction serial number of the initial ink drop points as a disabling condition; and the disabling processing mode of the initial ink drop points belonging to the sub-pixel pit area in the substrate takes serial numbers in two dimension directions of the disabled initial ink drop points as disabling conditions. Thereby, the processing efficiency of the disabling can be improved.
When the film thickness of the ink material in the substrate exceeds the value range of the target film thickness, as an example of the adjustment candidate disabling algorithm, the adjustment of the control command corresponding to the partial initial ink drop point in the substrate from the nozzle ink jet to the nozzle disabled can be achieved by: and obtaining the number of initial ink drop points needing to adjust the control instruction according to the ratio of the film thickness of the ink material in the substrate to the preset target film thickness. The quotient of the film thickness of the ink material in the substrate and the preset target film thickness and the number of initial ink drop points of which the control command is that the nozzle sprays ink is equal to the number of the initial ink drop points of which the control command needs to be adjusted. The preset target film thickness is any value in a value range of the target film thickness, and specifically may be a median of the value range of the target film thickness. According to the number of the initial ink drop points of the nozzle for ink jet, determining the initial ink drop points of the nozzle for ink jet according to the adjusted control instruction, so that the initial ink drop points of the nozzle for ink jet are uniformly distributed in the scanning direction of the printing nozzle and the vertical direction of the scanning direction of the printing nozzle; and determining the initial ink drop point of the control instruction to be modified according to the adjusted control instruction as the initial ink drop point of the nozzle for ink jet, and adjusting the control instruction to be modified in the substrate from the nozzle for ink jet to the nozzle for disabling. Thereby, uniformity of the ink material formed is ensured.
Specifically, assuming that the film thickness of the ink material in the substrate exceeds just one time of the preset target film thickness, the adjustment method may specifically be to disable the control instruction in the candidate disabling algorithm by half for the initial drop point of the ink ejected from the nozzle.
In some examples, an initial mapping of the number of ink drops to the thickness of the formed ink material may be determined by empirical values, and candidate disabling algorithms may be set based on the initial mapping, such that the set candidate disabling algorithms may be more accurate.
According to the embodiment of the application, a candidate disabling algorithm is set, and the film thickness of the ink material printed by the candidate disabling algorithm is obtained according to test verification. The initial ink drop point to be printed in the substrate can be adaptively adjusted so that the printed ink material meets the preset condition of the target film thickness, and the initial ink drop point can be adjusted more conveniently and controllably on the basis of improving the printing efficiency, so that the substrate with the ink material meeting the preset condition of the target film thickness can be printed more accurately.
In some embodiments, a variety of candidate disabling algorithms may be set to yield a target disabling algorithm through a test verification. In the test verification stage, in order to improve the efficiency of the test verification, the test verification may be performed by the following embodiments: uniformly arranging a plurality of areas and a plurality of sub-pixel pits arranged in each area on a substrate according to the size of the substrate; setting a corresponding candidate disabling algorithm for each region; wherein the candidate disabling algorithms corresponding to different regions are different from each other.
In some examples, printing each region in the substrate according to the candidate disabling algorithm corresponding to the region to obtain a film thickness of ink material in each region in the substrate; and determining the region with the film thickness of the ink material in the range of the target film thickness according to the film thickness of the ink material in each region, and taking the candidate disabling algorithm corresponding to the region as the target disabling algorithm.
Referring to fig. 6, there are a total of 6×6=36 areas (areas are not all shown) on a substrate, and there are a total of M sub-pixel pits (sub-pixel pits are not all shown) in one area, where M is a positive integer, and M is randomly allocated to each area according to a plurality of preset candidate disabling algorithms, for example, each area corresponds to a different candidate disabling algorithm, for example, area 1 corresponds to candidate disabling algorithm a, area 2 corresponds to candidate disabling algorithm B, and so on. Thus, printing a substrate can verify 36 candidate disabling algorithms.
Therefore, the embodiment of the application improves the efficiency of test and verification and saves the cost of test and verification by arranging the plurality of areas on the substrate and arranging different candidate disabling algorithms in the plurality of areas.
Referring to fig. 7, the inkjet printing control apparatus may be an MCU (micro controller unit), a PC (personal computer), a tablet computer, a portable computer, or a server, or the like.

Wherein the communication bus 702 is used to enable connected communications between these components. The user interface 703 may comprise a Display, an input unit such as a Keyboard (Keyboard), and the optional user interface 703 may also comprise a standard wired interface, a wireless interface. The network interface 704 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 705 may be a high-speed random access Memory (RandomAccessMemory, RAM) Memory or a stable nonvolatile Memory (NVM), such as a disk Memory. The memory 705 may alternatively be a storage device separate from the aforementioned processor 701.
It will be appreciated by those skilled in the art that the apparatus structure shown in fig. 7 is not limiting of the inkjet printing control apparatus, and may include more or fewer components than shown, or certain components may be combined, or a different arrangement of components.
As shown in fig. 7, an operating system, a network communication module, a user interface module, and an inkjet printing control application program may be included in the memory 705 as one type of computer storage medium.
In the device shown in fig. 7, the network interface 704 is mainly used for connecting to a background server, and is in data communication with the background server; the user interface 703 is mainly used for connecting a client and communicating data with the client; and the processor 701 may be used to call an inkjet printing control program stored in the memory 705 to implement the operations in the inkjet printing control method provided by the above embodiment.
The embodiment of the application also provides an ink-jet printing system which comprises the substrate, the ink-jet printing control equipment and the spray head equipment. Of course, it is understood that the inkjet printing system may also include other devices for ensuring proper operation of the inkjet printing system, such as a motion stage, a nozzle moving mechanism, a power supply, etc.

The preset multiple is an integer, for example, the preset multiple may be 2 or 3.
In the embodiment of the application, the distance between two adjacent sub-pixel pits in the substrate is a multiple of the distance between two adjacent initial ink drop points, so that the consistency of the initial ink drop points in which the control instruction is the nozzle ink jet in the sub-pixel pits can be ensured, namely, the relative positions of the initial ink drop points in each sub-pixel pit are the same, and the relative positions refer to the positions of the initial ink drop points in the sub-pixel pit relative to the sub-pixel pit corresponding to the initial ink drop points. The width of the sub-pixel pit is larger than the preset multiple times of the diameter of the initial ink drop point, so that one nozzle of the nozzle device can scan one sub-pixel pit, ink is dropped by one preset multiple times of printing (pass), and the printing efficiency is improved.
In some embodiments, referring to fig. 8, assuming that the size of the substrate is 10Nx10Nmm, the substrate is divided into Z regions, and M sub-pixel pits are in each region, the interval between two adjacent sub-pixel pits in the substrate is 5Num, the width of the sub-pixel pit in the substrate is 3Num, and it is possible to plan that the interval between two adjacent initial ink drop points in the substrate is Num; wherein M, Z is a positive integer, N is a positive number, and specific N can be 10, 20 and 30;801 is a substrate, 802 is a print head, 803 is a sub-pixel pit, 804 is an initial drop point, and 805 is a nozzle. It can be seen that in the scanning direction of the printing nozzle, two initial ink drop points of the nozzle for jetting ink are arranged in each sub-pixel pit by the control instruction, so that a single nozzle of the printing nozzle can scan one sub-pixel pit, and two ink drops can be continuously printed in one printing process.
When the interval between two adjacent initial ink drop points in the substrate is larger, a single nozzle of the printing nozzle is required to scan one sub-pixel pit for printing 2 drops of ink continuously at one time, and the interval between two adjacent sub-pixel pits in the substrate is required to be certain. To increase the versatility of inkjet printing systems. Referring to fig. 9, assuming that the size of the substrate is 10Nx10Nmm, the substrate is divided into Z regions, M sub-pixel pits are in each region, the pitch of two adjacent sub-pixel pits in the substrate is 5Num, the width of the sub-pixel pit in the substrate is 3Num,901 is the substrate, 902 is the print head, 903 is the sub-pixel pit, 904 is the initial drop point, 905 is the nozzle. In some embodiments, the interval between two adjacent initial ink drop points in the substrate can be set to be N/2um. It can be seen that three initial ink drop points of the nozzle for ejecting ink are arranged in each sub-pixel pit according to the control instruction in the scanning direction of the printing nozzle, so that a single nozzle of the printing nozzle can scan one sub-pixel pit, and three drops of ink can be printed at a time.
In the embodiment of the application, the distance between two adjacent initial ink drop points in the substrate is set to a reasonable range according to practical conditions (such as the size of the substrate, the distance between the sub-pixel pits, the width of the sub-pixel pits, the frequency of a printing nozzle, and the like), for example, 10um, and a plurality of initial ink drop points with control instructions of nozzle ink spraying are arranged in each sub-pixel pit in the scanning direction of the printing nozzle, so that when a single nozzle of the printing nozzle scans one sub-pixel pit, a plurality of ink drops can be printed at one time, and the printing efficiency is accelerated; and a plurality of initial ink drop points are provided, and as the number of the initial ink drop points is more, when a control instruction for adjusting the initial ink drop points is needed, the operability is stronger, so that the uniformity of the formed ink material is more controllably ensured.
