[0002] LED display screens are applied to various fields due to their advantages such as low cost, low power consumption, high visibility, and free assembly. Since LED screens are often used in splicing scenarios, gaps will be generated after splicing. Therefore, it is necessary to determine a gap adjustment coefficient to adjust the screen. In related technologies, a method of real pixel adjustment is provided.

However, since the sub-pixels in a sub-pixel display screen are different from real pixels, the method of real pixel adjustment is not applicable to the adjustment of sub-pixel display screens.

[0048] In the accompanying drawings, the same components are denoted by the same reference numerals, and the drawings are not drawn to actual scale. Detailed implementation manners

[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be construed as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0050] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0051] If similar descriptions such as "first / second / third" appear in the application documents, the following explanation is added. In the following description, the terms "first / second / third" only distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0053] Figure 1 It shows a schematic diagram of the structure of a real pixel in the related art. As Figure 1 shown, in an LED display screen, a real pixel is usually composed of three sub-pixels: red1, green2, and blue3. Each sub-pixel can emit light independently, and the combination of the three produces different colors and brightness. Generally, the seam repair coefficient is calculated according to the actual distance. At this time, since the RGB of the actual pixel is aggregated together, generally the same seam adjustment coefficient is used for RGB.

[0054] In the related art, for the seam adjustment method of actual pixels, the seam repair coefficient of pixel seams can be obtained through the following methods:

[0055] The examples are as follows. Continue to refer to Figure 1, the actual resolution is 4 * 8, the number of sub - pixels and light points is 4 * 8 * 3. The distance between normal light points is D0, and due to the influence of the splicing gap, the distance between some light points becomes D1.

[0056] The general formula for gap brightness adjustment is as follows:

[0057]

[0058] Among them, is the basic calculation method, is a correction value based on the basic calculation method, mainly considering the errors in the data collected by the camera. f(D1) will directly act on the real pixels on both sides of the gap, representing the seam - repairing coefficient.

[0059] Generally speaking, when adjusting real pixels, 1 row / 1 column of real pixels on both sides of the gap will be adjusted. This adjustment method is not applicable to sub - pixel gap adjustment, mainly because sub - pixel display involves a smaller display unit of pixels, that is, sub - pixels. The change in the judgment of the gap distance between sub - pixels is completely different from that of real pixels.

[0060] Figure 2 Fig. shows a schematic structural diagram of a 4 - light - point sub - pixel screen body. The sub - pixels include: three types of sub - pixels, namely red 4, green 5, and blue 6. As an assumption, if the above - mentioned real - pixel adjustment method is adopted and 1 row or 1 column of pixels is directly adjusted, there will be a color - deviation problem when people view the gap.

[0061] Figure 3 This is a display schematic diagram after real - pixel adjustment provided by an embodiment of the present application. As Figure 3 shown, the adjustment coefficients of regions 7 and 8 are calculated using formula (1). Due to different sub - pixels, when people view the gap, the left - hand light board will be bluish - green and the right - hand light board will be yellowish.

[0062] In the related art, the method of using real - pixel adjustment for sub - pixel screen body gap adjustment has a poor adjustment effect. That is, the method of using real - pixel adjustment is not applicable to the adjustment of sub - pixel displays.

[0063] Based on the problems existing in the related art, an embodiment of the present application provides a bright - dark line correction method. The execution subject of the method can be an electronic device, and the electronic device can be a mobile terminal, a computer, a sub - pixel display screen, etc. In some embodiments, the electronic device can be a controller of a mobile terminal, a computer, or a sub - pixel display screen.

[0064] The function realized by the bright - dark line correction method provided by an embodiment of the present application can be achieved by the processor of the electronic device calling program code, where the program code can be stored in a computer storage medium.

[0065] An embodiment of the present application provides a bright and dark line correction method. Figure 4 As shown in the schematic flowchart of the implementation of a bright and dark line correction method provided by an embodiment of the present application, Figure 4 as shown, the bright and dark line correction method includes:

[0066] Step S1, obtain the first distance between the adjustment unit on one side of the gap and the gap in the sub-pixel display screen, the second distance between two adjacent sub-pixels in the same row of sub-pixels, the third distance between the target sub-pixels on both sides of the gap, and the total number of adjustment units on both sides of the gap, where the adjustment unit includes at least: two sub-pixels, and the target sub-pixel is the sub-pixel in the same row and closest to the gap.

[0067] In an embodiment of the present application, the adjustment unit includes at least two sub-pixels, that is, the adjustment unit includes more than two sub-pixels. As an example, the adjustment unit includes at least a red sub-pixel and a green sub-pixel, or includes a red sub-pixel and a blue sub-pixel.

[0068] In an embodiment of the present application, step S1 may specifically include the following steps:

[0069] Determine the arrangement mode of the sub-pixel display screen. As an example, the sub-pixel arrangement modes include RGB, BGR, etc. Determining the arrangement mode helps to determine the position of the gap. As an example, the gap usually appears between adjacent sub-pixels, and the position of the gap can be determined by visual observation or tools such as magnifying glasses.

[0070] Determine the adjustment unit and the target sub-pixel on one side of the gap: According to the gap position and the sub-pixel arrangement mode, determine the adjustment unit and the target sub-pixel on one side of the gap. For example, if it is an RGB arrangement mode, the adjustment unit on one side of the gap may be a red sub-pixel, and the target sub-pixel is the sub-pixel closest to the gap.

[0071] Measure the distance: Use appropriate measurement tools to measure the first distance between the adjustment unit and the gap, the second distance between two adjacent sub-pixels in the same row of sub-pixels, and the third distance between the target sub-pixels on both sides of the gap.

[0072] Count the total number of adjustment units: Determine the total number of adjustment units on both sides of the gap to ensure that the adjustment unit includes at least two sub-pixels.

[0073] Figure 5 shows a structural example of a sub-pixel display screen according to an embodiment of the present application. As shown in Figure 5 as shown, the dotted box is an adjustment unit, and the second distance between two adjacent sub-pixels in the same row of sub-pixels can be referred to Figure 5Understand the distance marked by D0 shown in the figure. The third distance between the target sub-pixels on both sides of the gap can be referred to Figure 5 and understood as the distance marked by D1 shown in the figure.

[0074] In the embodiments of the present application, the parameters obtained above will be used in the subsequent bright and dark line correction process.

[0075] Step S2: Determine the target correction function value based on the first distance and the total number of adjustment units.

[0076] In the embodiments of the present application, the target correction function can be used to represent the degree of brightness correction required at a specific distance.

[0077] In the embodiments of the present application, the target correction function value can be calculated by inputting the first distance and the total number of adjustment units into the target correction function. Here, the target correction function can be a mathematical function used to calculate the target correction value for bright and dark line correction based on the first distance and the total number of adjustment units. It should be noted that the present application does not limit the specific function form, and the specific function form can be determined according to actual needs and system requirements.

[0078] In the embodiments of the present application, step S2 may specifically include the following steps:

[0079] Determine the form of the target correction function, and calculate the target correction function value according to the first distance and the total number of adjustment units. Use the determined target correction function, take the first distance and the total number of adjustment units as inputs, and calculate the corresponding target correction function value.

[0080] The calculation of the target correction function can be determined according to specific algorithms and requirements. For example, a linear function, an exponential function, or other suitable function forms can be used.

[0081] In the embodiments of the present application, through the above steps, the target correction function value for bright and dark line correction can be determined based on the first distance and the total number of adjustment units. Here, the target correction function value will be used in the subsequent brightness adjustment and bright and dark line correction processes.

[0082] Step S3: Determine the gap adjustment coefficient of the adjustment unit based on the target correction function value, the second distance, and the third distance.

[0083] In the embodiments of the present application, the gap adjustment coefficient represents the brightness adjustment ratio of the adjustment unit at a specific distance. Here, the correction coefficient of the adjustment unit calculated according to the target correction function value, the second distance, and the third distance is the gap adjustment coefficient.

[0084] In the embodiments of the present application, step S3 may specifically include the following steps:

[0085] In some embodiments, step S3 of determining the gap adjustment coefficient of the adjustment unit based on the target correction function value, the second distance, and the third distance can be implemented through the following steps:

[0086] Step S31: Divide the third distance by the second distance to obtain a first calculated value.

[0087] In this step, divide the third distance by the second distance to obtain a first calculated value. The formula is expressed as: First calculated value = Third distance / Second distance.

[0088] Exemplarily, the first calculated value can be expressed as:

[0089] In this step, through this calculation, a first calculated value can be obtained for the bright and dark line correction process in subsequent steps. It should be noted that the calculation process needs to ensure the consistency of distance units.

[0090] Step S32: Subtract 1 from the first calculated value to obtain a second calculated value.

[0091] In this step, subtract 1 from the first calculated value to obtain a second calculated value. The formula is expressed as: Second calculated value = First calculated value - 1.

[0092] In the embodiments of the present application, the second calculated value can be expressed as:

[0093] In this step, through this calculation, a second calculated value can be obtained for the bright and dark line correction process in subsequent steps. The purpose of this calculation is to convert the difference between the first calculated value and 1 into the second calculated value for subsequent correction and adjustment.

[0094] Step S33: Add the correction value to the second calculated value to obtain a third calculated value.

[0095] In this step, add the correction value to the second calculated value to obtain a third calculated value. The formula is expressed as: Third calculated value = Second calculated value + correction value.

[0096] In the embodiments of the present application, the third calculated value can be expressed as: where, is the correction value.

[0097] In this step, through this calculation, a third calculated value can be obtained for the bright and dark line correction process in subsequent steps. The correction value can be a fixed offset or a value dynamically calculated according to specific requirements and algorithms. The purpose of this calculation is to adjust the third calculated value based on the second calculated value and the correction value for subsequent bright and dark line correction.

[0098] Step S34: Multiply the third calculated value by the target correction function value to obtain a fourth calculated value.

[0099] In this step, multiply the third calculated value by the target correction function value to obtain a fourth calculated value. The formula is expressed as: Fourth calculated value = Third calculated value * Target correction function value.

[0100] In the embodiments of the present application, the fourth calculated value can be expressed as: where f(d, num) is the target correction function value.

[0101] In this step, through this calculation, a fourth calculated value can be obtained for use in the subsequent bright and dark line correction process. The target correction function value is determined according to the goals and requirements of the bright and dark line correction. It can be a fixed value or a dynamic value calculated according to a specific algorithm. The purpose of this calculation is to adjust the third calculated value according to the target correction function for use in the subsequent bright and dark line correction.

[0102] Step S35: Add 1 to the fourth calculated value to obtain the gap adjustment coefficient of the adjustment unit.

[0103] In this step, add 1 to the fourth calculated value to obtain the gap adjustment coefficient of the adjustment unit. The formula is expressed as: Gap adjustment coefficient of the adjustment unit = Fourth calculated value + 1.

[0104] In the embodiments of the present application, the gap adjustment coefficient can be expressed as:

[0105] where

[0106] f(d) is a function of the position distance d of the current adjustment unit from the gap. f(num) is a function of the number num of adjustment units in the current adjustment strategy. is the correction value. f(D1, d, num) is the gap adjustment coefficient.

[0107] In this step, through this calculation, the final gap adjustment coefficient of the adjustment unit can be obtained. This coefficient is used to adjust and correct the gap adjustment in the bright and dark line correction process to achieve the desired bright and dark line effect. The purpose of adding 1 to the fourth calculated value is to ensure that the gap adjustment coefficient of the adjustment unit is always positive to ensure the accuracy and stability of the correction process.

[0108] In these embodiments, through the above steps, the gap adjustment coefficient of the adjustment unit can be calculated based on the target correction function value, the second distance, and the third distance. These calculation steps can be adjusted and optimized according to actual needs and system requirements to ensure obtaining an accurate gap adjustment coefficient to achieve bright and dark line correction.

[0109] Step S4, adjust the display brightness of the adjustment unit based on the gap adjustment coefficient to adjust the sub-pixel display screen.

[0110] In the embodiments of the present application, the method for adjusting the display brightness of the adjustment unit can be determined according to specific requirements and system requirements. As an example, it can be achieved by changing the driving current, adjusting the pixel voltage, or applying a specific correction algorithm.

[0111] In the embodiments of the present application, through the above steps, the display brightness of the adjustment unit is adjusted according to the gap adjustment coefficient, so as to perform bright-dark line correction on the sub-pixel display screen. In this way, the effect of correcting the bright-dark line can be achieved by adjusting the display brightness of the adjustment unit.

[0112] According to the bright-dark line correction method provided by the embodiments of the present application, by obtaining the first distance between the adjustment unit on one side of the gap and the gap in the sub-pixel display screen, the second distance between two adjacent sub-pixels in the same row of sub-pixels, the third distance between the target sub-pixels on both sides of the gap, and the total number of adjustment units on both sides of the gap, where the adjustment unit at least includes: two sub-pixels, and the target sub-pixel is the sub-pixel in the same row and closest to the gap, determining the target correction function value based on the first distance and the total number of adjustment units, determining the gap adjustment coefficient of the adjustment unit based on the target correction function value, the second distance, and the third distance, and adjusting the display brightness of the adjustment unit based on the gap adjustment coefficient to adjust the sub-pixel display screen. In this way, the bright-dark line of the sub-pixel display screen can be corrected.

[0113] According to the present application, the target correction function value and the gap adjustment coefficient can be determined according to different distances and the number of adjustment units, so as to realize the bright-dark line correction of the sub-pixel display screen. This method can improve the display consistency and detail performance. For example, when adjusting the brightness of sub-pixels, it is necessary to ensure that the overall spliced image is visually continuous without breaks, presenting continuous and consistent image content. This may involve non-uniform brightness adjustment of the sub-pixels on both sides of the gap.

[0114] In some embodiments, step S2, determining the target correction function value based on the first distance and the total number of adjustment units, includes:

[0115] Step S21, obtain the pre-established correspondence table, and each group of correspondences in the correspondence table includes: the correspondence between the distance, the total number of adjustment units, and the correction function value, where the distance is used to represent the distance between the adjustment unit and the gap.

[0116] Table 1 is a schematic table of a correspondence table provided by the embodiments of the present application. As shown in Table 1:

[0117]

[0118] In this step, the correspondence table is pre-established based on experimental data, and each set of correspondences describes the distance between the adjustment unit and the slit. The purpose of the correspondence table is to correspond different distances and the total number of adjustment units to appropriate correction function values to achieve the effect of adjusting the bright and dark lines according to the actual situation.

[0119] In this step, through the records in the correspondence table, appropriate distances and the total number of adjustment units can be matched according to the actual situation to obtain the corresponding correction function values for the bright and dark line correction process in the subsequent steps.

[0120] In some embodiments, the correspondence table includes: a first correspondence and a second correspondence. The adjustment units corresponding to the distances in the first correspondence are on one side of the slit, and the adjustment units corresponding to the distances in the second correspondence are on the other side of the slit. The sum of all the correction function values corresponding to the first correspondence is equal to 0.5, and the sum of all the correction function values corresponding to the second correspondence is equal to 0.5. In the case where the distance in the target first correspondence is equal to the distance in the target second correspondence, the correction function value corresponding to the target first correspondence is equal to that of the target second correspondence. It should be noted that the slit is located between adjacent sub-pixels being spliced, and one side and the other side of the slit belong to the opposite sides of the slit, and the corresponding adjustment units are located on two adjacent sub-pixels.

[0121] Step S22: Match the first distance and the total number of adjustment units with the distances and the total number of adjustment units in each set of correspondences to obtain a matching result.

[0122] In this step, through the matching, a matching result can be obtained, that is, the correspondence that best matches the first distance and the total number of adjustment units is found.

[0123] In this step, step S22 specifically may include the following steps:

[0124] Obtain the first distance and the total number of adjustment units.

[0125] Traverse each record in the correspondence table.

[0126] For each record, compare the distance and the total number of adjustment units therein with the first distance and the total number of adjustment units. As an example, if a matching distance and total number of adjustment units are found, that is, the distance and the total number of adjustment units in the record are exactly the same as the first distance and the total number of adjustment units, then the matching is successful. If multiple matching records are found, the closest one or other specified selection strategies can be selected. If no matching record is found, other strategies may need to be adopted or default values may be used.

[0127] The matching result is the record that matches the first distance and the total number of adjustment units, and this record contains the corresponding correction function value. The matching result will be used in the subsequent bright and dark line correction process to determine the target correction function value.

[0128] Step S23, determine the target correspondence based on the matching result.

[0129] In this step, the matching result is the record that matches the first distance and the total number of adjustment units found in step S22, where the record contains the corresponding correction function value.

[0130] Based on the matching result, the target correspondence can be determined, that is, determine the correction function value corresponding to the distance between the adjustment unit and the slit.

[0131] Based on the determination of the target correspondence, it can be ensured that during the bright and dark line correction process, the appropriate correction function value is selected according to the actual situation to achieve the desired bright and dark line effect.

[0132] Step S24, determine the correction function value in the target correspondence as the target correction function value.

[0133] In this step, the target correspondence is determined based on the matching result in step S23, which contains the distance between the adjustment unit and the slit and the corresponding correction function value.

[0134] Determining the correction function value in the target correspondence as the target correction function value means using this correction function value as the target value in the correction process. This target value will be used in the subsequent bright and dark line correction process to adjust the bright and dark line effect.

[0135] In this step, by determining the correction function value in the target correspondence as the target correction function value, it can be ensured that the correct target value is used in the correction process to achieve accurate and stable bright and dark line correction.

[0136] In these embodiments, according to the pre-established correspondence table, by matching and determining the correspondence, the appropriate correction function value can be obtained to achieve the target effect of bright and dark line correction.

[0137] In some embodiments, in step S22, matching the first distance, the total number of adjustment units with the distance and the total number of adjustment units in each group of correspondences includes:

[0138] Step S221, calculate the similarity between the first distance, the total number of adjustment units and the distance, the total number of adjustment units in each group of correspondences.

[0139] In this step, the similarity is used to measure the similarity between the first distance, the total number of adjustment units, and the distance and the total number of adjustment units in each group of corresponding relationships. The similarity calculation method can be, for example, Euclidean distance, cosine similarity, etc. Based on the similarity calculation, it is beneficial to find the most matching combination according to the actual situation for bright and dark line correction.

[0140] Step S222, perform matching based on the similarity.

[0141] In this step, according to the calculated similarity value, a matching process is carried out to find the most matching combination. In this way, the appropriate correction function value can be determined for subsequent calculation of the gap adjustment coefficient.

[0142] In this step, by calculating the similarity, the first distance and the total number of adjustment units can be matched with the distance and the total number of adjustment units in each group of corresponding relationships. The goal of the matching is to find the corresponding relationship with the highest similarity to the first distance and the total number of adjustment units.

[0143] In these embodiments, through these two steps, the similarity between the first distance and the total number of adjustment units and the distance and the total number of adjustment units in each group of corresponding relationships can be calculated, and matching is performed based on the similarity. The matching result will be used in the subsequent bright and dark line correction process to determine the target corresponding relationship and the target correction function value. In this way, it can be ensured that the appropriate corresponding relationship and correction function value are selected according to the actual situation to achieve an accurate bright and dark line correction effect.

[0144] In some embodiments, in step S1, obtain the first distance between the adjustment unit on one side of the gap and the gap in the sub-pixel display screen, the second distance between two adjacent sub-pixels in the same row of sub-pixels, the third distance between the target sub-pixels on both sides of the gap, and the total number of adjustment units on both sides of the gap, where the adjustment unit includes at least: two sub-pixels, and the target sub-pixel is the sub-pixel in the same row and closest to the gap, including:

[0145] Step S11, collect the image information of the sub-pixel display screen.

[0146] In this step, the image information of the sub-pixel display screen can be obtained through a corresponding sensor or device for subsequent analysis and processing. As an example, the image information of the sub-pixel display screen can be obtained through a camera, a scanner, or other image acquisition devices. The collected image information will include details such as sub-pixels and gaps on the sub-pixel display screen for subsequent processing and analysis.

[0147] In this step, the collected image information will be used for operations such as identifying sub-pixels and gaps, dividing adjustment units, and determining the distance and number between the adjustment unit and the gap.

[0148] Step S12: Identify sub-pixels and gaps in the sub-pixel display based on the image information.

[0149] In this step, image processing and computer vision techniques can be used to identify sub-pixels and gaps in the sub-pixel display.

[0150] In this step, step S12 includes the following sub-steps:

[0151] Preprocessing: Preprocess the collected image, including operations such as denoising, enhancing contrast, and edge detection, to better identify sub-pixels and gaps.

[0152] Feature extraction: Use image processing algorithms to extract features in the image, such as color, shape, texture, etc., to distinguish sub-pixels and gaps.

[0153] Segmentation: Use image segmentation techniques to segment sub-pixels and gaps in the image for subsequent identification and analysis.

[0154] Detection and recognition: Use computer vision algorithms to detect and recognize sub-pixels and gaps in the image, and different brightness, contrast, and angle situations may need to be considered.

[0155] Through the above steps, the operation of identifying sub-pixels and gaps in the sub-pixel display based on the image information can be achieved, providing a necessary data basis for subsequent analysis and processing.

[0156] Step S13: Divide on both sides of the gap with at least two sub-pixels as one adjustment unit to obtain a division result.

[0157] In this step, step S13 may include the following steps:

[0158] Sub-pixel grouping: Group the identified sub-pixels according to the specified grouping method to ensure that each adjustment unit contains at least two sub-pixels.

[0159] Division on both sides of the gap: According to the structure and layout of the sub-pixel display, divide the grouped sub-pixels on both sides of the gap to ensure that each adjustment unit is located on one side of the gap.

[0160] Obtain the division result: Record the position of each adjustment unit and the sub-pixels it contains to obtain the division result for subsequent processing and analysis.

[0161] In this step, through the above steps, it is possible to divide on both sides of the gap with at least two sub-pixels as one adjustment unit and obtain the division result. The result of this step will provide the necessary data basis for the subsequent determination of the number of adjustment units and distance calculation. This step divides the sub-pixels in the sub-pixel display screen into adjustment units for subsequent calculation of the first distance, second distance, and third distance.

[0162] Step S14, determine the number of adjustment units on both sides of the gap based on the division result, where the number of adjustment units on both sides of the gap is the same.

[0163] In this step, determine the number of adjustment units on both sides of the gap according to the division result to ensure that the number of adjustment units on both sides of the gap is the same.

[0164] In this step, step S14 may include the following steps:

[0165] Count adjustment units: According to the division result, count the number of adjustment units included on both sides of the gap.

[0166] Adjustment unit matching: Ensure that the number of adjustment units on both sides of the gap is the same. If differences are found, it may be necessary to adjust the division result or perform additional processing to match the number of adjustment units.

[0167] Determine the number: Finally, determine the number of adjustment units on both sides of the gap and record it for subsequent use.

[0168] In this step, through the above steps, it is possible to determine the number of adjustment units on both sides of the gap based on the division result and ensure that they are the same. The result of this step will provide the necessary data basis for the subsequent distance calculation and adjustment unit analysis.

[0169] Step S15, determine the total number of adjustment units on both sides of the gap based on the number of adjustment units on both sides of the gap.

[0170] In this step, it is necessary to determine the total number of adjustment units on both sides of the gap based on the number of adjustment units on both sides of the gap. This step can be completed through a simple addition operation, that is, adding the number of adjustment units on both sides of the gap to determine the total number of adjustment units on both sides of the gap.

[0171] In this step, step S15 specifically includes the following steps:

[0172] Obtain the number of adjustment units on both sides of the gap.

[0173] Add the number of adjustment units on both sides of the gap to obtain the total number of adjustment units on both sides of the gap.

[0174] Record the total number of adjustment units on both sides of the gap for subsequent use.

[0175] In this step, through the above steps, the total number of adjustment units on both sides of the gap can be determined based on the number of adjustment units on both sides of the gap. The result of this step will provide the necessary data basis for subsequent distance calculation and adjustment unit analysis.

[0176] Step S16, determine the first distance, the second distance, and the third distance based on the adjustment unit and the gap.

[0177] In this step, according to the positional relationship between the adjustment unit and the gap, determine the first distance, the second distance, and the third distance, providing the necessary parameters for subsequent bright and dark line correction.

[0178] In this step, step S16 specifically includes the following steps:

[0179] First distance: The first distance usually refers to the distance between adjacent adjustment units and can be determined by measuring the width of the adjustment unit.

[0180] Second distance: The second distance usually refers to the width of the gap between adjacent adjustment units and can also be determined by measurement.

[0181] Third distance: The third distance usually refers to the distance between three adjacent adjustment units, including two adjustment units and the gap between them, and can also be determined by measurement.

[0182] Record the measurement results: Record the measured first distance, second distance, and third distance for subsequent use.

[0183] In this step, through the above steps, the first distance, the second distance, and the third distance can be determined based on the adjustment unit and the gap. The determination of these distances will help analyze and process the structure and layout of the sub-pixel display screen subsequently.

[0184] In these embodiments, the above steps help to obtain the distance and number information between the adjustment unit on one side of the gap and the gap in the sub-pixel display screen, providing the necessary data basis for the subsequent steps of the bright and dark line correction method.

[0187] Judging from the data, the brightness adjustment of this solution is more delicate, and the visual effect on the human eye is better. In terms of color cast, since the RGGB sub-pixels on both sides will be adjusted, the color effect will also be more consistent.
