[0003] However, existing inkjet printers are affected by printhead quality, operating environment, and usage time, leading to nozzle damage or precision loss. This results in low- to mid-range printheads being unable to print on high-precision display panels. Current technologies attempt to mitigate this issue by periodically replacing or maintaining printheads. However, these methods increase printing costs and cycle times, and cannot meet the high-precision and high-efficiency automatic printing requirements for the high-precision pixel grooves of glass display panels. Therefore, improving printing precision control to achieve high-precision display panel printing is a pressing issue that needs to be addressed. Summary of the Invention

[0031] Example 1

[0032] Figure 1 This is a flowchart of a high-precision image splitting and printing method provided in Embodiment 1 of the present invention. This embodiment is applicable to the high-precision and high-efficiency automatic printing of high-precision pixel slots on glass display panels. The method can be executed by a high-precision image splitting and printing device, which can be implemented in hardware and / or software. This high-precision image splitting and printing device can be configured in an electronic device, for example, in a computer device. Figure 1 As shown, the method includes:

[0033] S110. Print specific test data through the current printhead to obtain imaging ink dots, and determine the current printhead information based on the current position of the imaging ink dots; wherein, the current printhead information includes: printhead parameters, clogging points, ink volume accuracy, and position accuracy.

[0034] Here, "current printhead" refers to the printhead in the inkjet printer that requires improved printing accuracy. "Specific test data" refers to test strips pre-generated based on the relevant parameters of the current printhead. Typically, specific test data includes the landing positions of each ink droplet; thus, the state of the current printhead can be detected using specific test materials. "Imaging ink droplets" refers to the ink droplets obtained after the current printhead prints the specific test data.

[0035] The current printhead information refers to the current status information of the printhead. For example, it may include printhead parameters, clogging points, ink volume accuracy, and position accuracy. Printhead parameters may refer to the nozzle parameters contained in the current printhead. For example, it may be the sequence number of each nozzle. Clogging points may refer to the sequence number of nozzles that are clogged or have deviations such as misaligned spraying. Ink volume accuracy may refer to the ink volume accuracy of each nozzle in the current printhead. Position accuracy may refer to the ink spraying position accuracy of each nozzle in the current printhead.

[0036] Specifically, after the printhead prints specific test data to obtain image ink dots, visual inspection technology can be used to identify the ink volume of each ink dot in the image ink dots and locate the printing landing position. Then, the ink volume and printing landing position corresponding to the image ink dots are compared with the ink volume and landing position recorded in the specific test data to obtain the ink volume accuracy and position accuracy.

[0037] S120. Obtain the panel parameters of the current display panel, and perform step compensation on the current printhead based on the panel parameters, printhead parameters in the current printhead information, clogging points and ink volume accuracy to obtain the target landing point combination.

[0038] Here, "current display panel" can refer to the actual display panel used for printing. For example, it can be a glass display panel. "Panel parameters" can refer to the parameter information of the current display panel. For example, it can include slot size, slot position, number of slots, ink application amount, and tolerance value. Typically, the panel parameters of the current display panel are set uniformly by the manufacturer, and this embodiment of the invention does not impose any restrictions on this.

[0039] Step compensation refers to compensating for the number of steps of the current printhead, so that the ink droplets ejected by the current printhead after step compensation can evenly cover all slots of the current display panel. Target landing point combination refers to the combination of the optimal nozzle opening sequence and the optimal step value.

[0040] S130. Based on the position accuracy in the current nozzle information, perform position compensation on the current nozzle to obtain the target position compensation.

[0041] Position compensation refers to compensating for the printing position of the current printhead so that the ink droplets ejected from the current printhead can accurately fall into the respective slots of the current display panel. Target position compensation refers to the compensation value of the position compensation.

[0042] S140: Based on the target landing point combination and target position compensation, control the current printhead to actually print on the current display panel to generate a high-precision split map.

[0043] Specifically, after obtaining the target landing point combination and target position compensation, the target landing point combination and target position compensation can be used to control the current printhead to actually print on the current display panel, thereby generating a high-precision split image.

[0044] The technical solution of this invention involves controlling the current printhead to print specific test data to obtain imaging ink dots, and determining the current printhead information based on the current position of the imaging ink dots. Then, the panel parameters of the current display panel are acquired, and the current printhead is step-compensated based on the panel parameters, the printhead parameters in the current printhead information, clogging points, and ink volume accuracy to obtain a target landing point combination. Further, the current printhead is position-compensated based on the position accuracy in the current printhead information to obtain target position compensation. Finally, the current printhead is controlled to perform actual printing on the current display panel based on the target landing point combination and target position compensation, generating a high-precision image. This solves the problem of low printing accuracy in existing technologies, which prevents the achievement of high-precision display panel printing. It can meet the requirements of high-precision and high-efficiency automatic printing of high-precision pixel slots, improving printing accuracy and achieving high-precision display panel printing.

[0045] Example 2

[0046] Figure 2 This is a flowchart of a high-precision printing method for image splitting according to Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Specifically, this embodiment refines the operation of performing step compensation on the current printhead based on panel parameters, printhead parameters in the current printhead information, clogging points, and ink volume accuracy to obtain a target landing point combination. Specifically, it may include: determining the parameter validity of the current printhead information and initial step value, obtaining basic current printhead information and basic initial step value that meet the parameter validity requirements; determining the simulated tank bottom map based on the panel parameters of the current display panel; determining the target step value using the basic initial step value, and controlling the current printhead to form simulated ink dots in the simulated tank bottom map using the target step value; selecting a target landing point combination from the simulated ink dots based on the printhead parameters, clogging points, and ink volume accuracy in the basic current printhead information; wherein, the target landing point combination includes a target step value and a target nozzle combination. Figure 2 As shown, the method includes:

[0047] S210. Print specific test data through the current printhead to obtain imaging ink dots, and determine the current printhead information based on the current position of the imaging ink dots; wherein, the current printhead information includes: printhead parameters, clogging points, ink volume accuracy and position accuracy.

[0048] S220. Parameter legalization: Determine the current nozzle information and initial step value, and obtain the basic current nozzle information and basic initial step value that meet the parameter legalization requirements.

[0049] The initial step value refers to the number of steps in the current nozzle's initial state. Parameter validity verification refers to the operation of checking the accuracy of the input current nozzle information and initial step value. Parameter validity verification can prevent the input of incorrect current nozzle information and initial step value.

[0050] Here, "basic current nozzle information" can refer to the current nozzle information that meets the parameter validity requirements. "Basic initial step value" can refer to the initial step value that meets the parameter validity requirements.

[0051] In one optional implementation, the parameter validation process, which determines the current nozzle information and initial step value to obtain basic current nozzle information and basic initial step value that meet the parameter validation requirements, may include: obtaining the current nozzle information and initial step value; performing a consistent comparison between the current nozzle information and preset current nozzle information to obtain basic current nozzle information that meets the parameter validation requirements; and performing a consistent comparison between the initial step value and preset initial step value to obtain basic initial step value that meets the parameter validation requirements.

[0052] The preset current nozzle information refers to the pre-set parameter information of the current nozzle. The preset initial step value refers to the pre-set initial step value. It is worth noting that both the preset current nozzle information and the preset initial step value can be set according to the actual state parameters of the current nozzle.

[0053] Specifically, after obtaining the input current nozzle information, it can be compared with preset current nozzle information. If the current nozzle information does not match the preset current nozzle information (e.g., if the preset current nozzle information has 1024 nozzles, while the current nozzle information has 1023 or 1025 nozzles), the current nozzle information is discarded. Conversely, if the current nozzle information matches the preset current nozzle information, it is used as the base current nozzle information. Similarly, after obtaining the input initial step value, it can be compared with a preset initial step value. If the initial step value does not match the preset initial step value, it is discarded. Conversely, if the initial step value matches the preset initial step value, it is used as the base initial step value. This ensures the accuracy of the input data and provides a valid basis for subsequent operations.

[0054] S230. Determine the simulation tank bottom diagram based on the panel parameters of the current display panel.

[0055] The simulated slot bottom map refers to a slot bottom map generated based on the panel parameters of the current display panel. Specifically, the simulated slot bottom map can be drawn based on the slot size, slot position, and number of slots of the current display panel.

[0056] S240. Determine the target step value using the basic initial step value, and use the target step value to control the current printhead to form simulated ink dots in the simulated tank bottom map.

[0057] The target step value can refer to the final determined step value of the current printhead. The simulated ink droplet can refer to the ink droplet that falls from the current printhead in the simulated tank bottom map according to the target step value.

[0058] In one optional implementation, determining a target step value using a basic initial step value and controlling the current printhead to form simulated ink dots in the simulated slot bottom image using the target step value may include: controlling the current printhead to form initial ink dots in the simulated slot bottom image based on the printhead starting position coordinates in the printhead parameters and the basic initial step value; if the initial ink dot amount of the target row pixel slot in the simulated slot bottom image does not meet the ink drop amount in the panel parameters, increasing the basic initial step value by a step value based on a preset threshold as the target step value, and controlling the current printhead to form simulated ink dots in the simulated slot bottom image using the target step value.

[0059] Here, the initial ink droplet refers to the ink droplet that falls from the current printhead in the simulated slot bottom image based on the basic initial step value. The target row pixel slot refers to a single row pixel slot in the simulated slot bottom image, i.e., the simulated slot bottom. Figure 1 All pixel slots in the row. Initial ink dot amount can refer to the initial ink dot amount. For example, it could be five dots or ten dots, etc. Preset threshold can refer to a pre-set value used to improve the base initial step value.

[0060] Specifically, the current printhead is controlled to move based on its initial position coordinates and the basic initial step value. Based on the relative positions of the nozzles on the current printhead, the nozzle positions after the step are calculated. Then, the initial ink droplet positions of each nozzle are mapped based on their positions. Finally, the initial ink droplet volume of each initial ink droplet is calculated based on the ink volume accuracy of each nozzle. If simulating the bottom of the tank... Figure 1 The initial ink droplet amount for all pixel slots in the row cannot meet the ink droplet amount specified in the panel parameters. This means that after the printhead moves according to the basic initial step value, the generated initial ink droplets cannot fill all slot positions in the simulated slot bottom image. Therefore, it is necessary to increase the basic initial step value of the current printhead according to a preset threshold and decrease the step amount of the current printhead. This ensures that the ink droplets generated when the current printhead moves according to the target step value can fill all slot positions in the simulated slot bottom image, thus improving printing accuracy.

[0061] It is worth noting that after determining the target step value, it is also necessary to control the current printhead to form ink dots in the simulated slot bottom image based on the printhead's starting position coordinates and the target step value. When the amount of ink dots in the target row pixel slot in the simulated slot bottom image meets the ink drop amount in the panel parameters, the target step value is selected. Otherwise, it is still necessary to increase the step value of the target step value according to the preset threshold until the amount of ink dots in the target row pixel slot in the simulated slot bottom image meets the ink drop amount in the panel parameters.

[0062] S250. Based on the printhead parameters, clogging points, and ink volume accuracy in the current printhead information, select a target landing point combination in the simulated ink dots; wherein, the target landing point combination includes the target step value and the target nozzle combination.

[0063] The target nozzle combination can refer to a combination of nozzle sequences that meet the ink drop requirements in the panel parameters.

[0064] In one optional implementation, selecting a target landing point combination from simulated ink dots based on the nozzle parameters, clogging points, and ink volume accuracy in the current basic nozzle information may include: obtaining the landing point position and nozzle number of the simulated ink dots in the simulated tank bottom image after a single step; determining a target nozzle combination that meets the ink volume requirements in the panel parameters from the landing point position and nozzle number of the generated simulated ink dots based on the nozzle parameters, clogging points, and ink volume accuracy in the current basic nozzle information; and combining the target nozzle combination with the target step value to determine the target landing point combination.

[0065] Specifically, given the nozzle numbers and clogging points of each nozzle in the current printhead, after a single step, the corresponding nozzle number can be determined by simulating the ink droplet landing position in the simulated tank bottom diagram. Then, based on the ink drop volume in the panel parameters and the inkjet accuracy of each nozzle, the optimal nozzle combination is selected as the target nozzle combination. For example, if after a single step, the simulated ink droplet landing positions in the simulated tank bottom diagram are 1, 3, and 5, the nozzle numbers generating the ink droplets are 1, 2, 3, 4, and 5, the ink volume accuracy of each nozzle is 5, and the ink drop volume in the panel parameters is 10, then to ensure printing uniformity, nozzle numbers 2 and 4 can be turned off, and nozzle numbers 1, 3, and 5 can be combined to generate the target nozzle combination.

[0066] S260. Obtain the current horizontal position of the current nozzle at the target scanning position and the position accuracy in the current nozzle information.

[0067] The target scanning position can refer to the pre-defined printing direction of the current printhead. For example, it can be the installation direction of the current printhead, such as the x-direction. The current horizontal position can refer to the coordinates of the current printhead at the target scanning position.

[0068] S270. The position accuracy of the current horizontal position is compensated according to the preset standard position to obtain the target position compensation.

[0069] The preset standard position can refer to the pre-defined printing position coordinates. For example, it can be the groove position coordinates in the simulated groove bottom image, or it can be the coordinates of the groove position in the simulated groove bottom image on the target scanning position.

[0070] Specifically, if there is a deviation between the current horizontal position of the printhead at the target scanning position and the preset standard position, the positional accuracy of each nozzle at the current horizontal position can be compensated according to the preset standard position. Thus, by increasing the resolution of the target scanning position, pixel-level nozzle compensation can be performed to improve printing accuracy.

[0071] S280. Based on the target position compensation, perform position compensation on the actual horizontal position of the current nozzle at the actual scanning position to obtain the position compensation result.

[0072] The actual scanning position refers to the printing direction of the printhead during the actual printing process. The actual horizontal position refers to the coordinates of the printhead at the actual scanning position. The position compensation result refers to the result after compensating the actual horizontal position of the printhead based on the target position compensation.

[0073] Specifically, after determining the combination of target position compensation and target landing point, the actual horizontal position of the current nozzle at the actual scanning position can be compensated based on the target position compensation. This achieves pixel-level nozzle compensation, providing an effective foundation for the subsequent generation of high-precision map breakdown.

[0074] S290: Based on the position compensation result, control the current nozzle to land according to the target landing point combination, and generate a high-precision map.

[0075] Specifically, after position compensation is performed on the actual horizontal position of the current nozzle at the actual scanning position based on the target position compensation, the opening or closing of each nozzle in the current nozzle can be controlled according to the target nozzle combination in the target landing point combination, and the current nozzle can be controlled to move according to the target step value in the target landing point combination, thereby generating a high-precision map.

[0076] The technical solution of this invention involves controlling the current printhead to print specific test data to obtain imaging ink dots, and determining the current printhead information based on the current position of the imaging ink dots. Then, it acquires basic current printhead information and basic initial step values ​​that meet parameter validation requirements, determines a target step value using the basic initial step value, and uses the target step value to control the current printhead to form simulated ink dots in a simulated slot bottom map determined based on the panel parameters of the current display panel. Based on the printhead parameters, clogging points, and ink volume accuracy in the basic current printhead information, it selects a target landing point combination from the simulated ink dots. Furthermore, it acquires the current horizontal position of the current printhead at the target scanning position. The system calculates the position and accuracy of the current printhead information, compensates for the position accuracy of the current horizontal position based on a preset standard position, and obtains the target position compensation. Finally, it compensates for the actual horizontal position of the current printhead at the actual scanning position based on the target position compensation, obtains the position compensation result, and controls the current printhead to land according to the target landing point combination based on the position compensation result, generating a high-precision image. This solves the problem of low printing accuracy in existing technologies, which makes it impossible to achieve high-precision display panel printing. It can meet the requirements of high-precision and high-efficiency automatic printing of high-precision pixel slots, improves printing accuracy, and realizes high-precision display panel printing.

[0077] Figure 3 The diagram shows a flowchart of a step compensation process provided by an embodiment of the present invention. Specifically, firstly, the current printhead information and initial step value are obtained; parameter validity is determined based on the current printhead information and initial step value to obtain basic current printhead information and basic initial step value that meet the parameter validity requirements; then, a simulated slot bottom map is determined based on the panel parameters of the current display panel; further, the current printhead is controlled to form initial ink dots in the simulated slot bottom map based on the printhead starting position coordinates and basic initial step value in the printhead parameters; it is determined whether the initial ink dot amount of the target row pixel slot in the simulated slot bottom map meets the ink drop amount in the panel parameters; if so, the basic initial step value is determined. The target step value is set as follows: if not, the step value is the step value that is increased by the basic initial step value according to the preset threshold, and the target step value is used to control the current printhead to form simulated ink dots in the simulated tank bottom map; further, the landing position and nozzle number of the simulated ink dots in the simulated tank bottom map after a single step are obtained; based on the printhead parameters, clogging points and ink volume accuracy in the basic current printhead information, the target nozzle combination that meets the ink volume requirements in the panel parameters is determined from the landing position and nozzle number of the generated simulated ink dots; finally, the target nozzle combination is combined with the target step value to determine the target landing point combination.

[0078] It is worth noting that, in this embodiment of the invention, if it is determined that the current nozzle information and the initial step value do not meet the parameter validity requirements, a pop-up window in the form of "failure + reason + solution" can be output, specifically "failure + parameter (1024 nozzle) does not match the current nozzle (2040 nozzle) + replace nozzle", so as to facilitate subsequent improvements.

[0079] Figure 4 The diagram shows a flowchart of an optional high-precision image splitting printing method provided by an embodiment of the present invention. Specifically, firstly, the panel parameters of the current display panel and the current printhead information of the current printhead are obtained; then, the position of the current printhead is compensated according to the position accuracy in the current printhead information to obtain the target position compensation; further, the pixel slot landing point in the stepping direction is determined according to the target position compensation; and, step compensation is performed on the current printhead according to the panel parameters, the printhead parameters in the current printhead information, the clogging point, and the ink volume accuracy to obtain the target landing point combination; finally, the current printhead is controlled to perform actual printing on the current display panel according to the target landing point combination and the target position compensation to generate a high-precision image splitting.

[0084] The position compensation module 330 is used to perform position compensation on the current nozzle based on the position accuracy in the current nozzle information to obtain the target position compensation.

[0085] The image splitting generation module 340 is used to control the current printhead to actually print on the current display panel based on the target landing point combination and target position compensation, and generate a high-precision image splitting.

[0086] The technical solution of this invention involves controlling the current printhead to print specific test data to obtain imaging ink dots, and determining the current printhead information based on the current position of the imaging ink dots. Then, the panel parameters of the current display panel are acquired, and the current printhead is step-compensated based on the panel parameters, the printhead parameters in the current printhead information, clogging points, and ink volume accuracy to obtain a target landing point combination.
