Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and particularly relates to a color deviation display adjustment method, device and system applied to an LCD monitor. Background Art

[0002] During the manufacturing process of an LCD monitor (Liquid Crystal Display), due to cost control, material differences, and production process influences, color deviation phenomena often occur, which in turn leads to a deviation between the display effect and the actual color. Color deviation adjustment for an LCD monitor is an important step to ensure accurate color reproduction. Color deviation adjustment usually needs to be completed through professional equipment such as a colorimeter. By combining hardware and software for color calibration, the color performance can be significantly improved, thereby providing users with a more real and accurate visual experience.

[0003] In existing color deviation adjustment methods, a colorimeter is usually used to measure the color deviation pixel points of an LCD monitor and generate a configuration file containing color correction data to correct the color output of the monitor. The colorimeter projects color samples on the monitor and records the reflected spectral data. However, when the colorimeter conducts color evaluation, the pixel point area with color deviation may also be abnormal color display caused by reasons such as the liquid crystal layer, thin film transistor, or backlight problem, and these defective areas will be misidentified as adjustable areas, thereby reducing the accuracy of color deviation adjustment.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0056] The following specifically describes the specific solutions of a color deviation display adjustment method, device and system applied to an LCD monitor provided by the present invention with reference to the accompanying drawings.

[0057] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the implementation environment of a color deviation display adjustment method applied to an LCD monitor provided by an embodiment of the present invention. As Figure 1As shown in the figure, the implementation environment includes a color deviation display adjustment terminal 101, an information collection terminal 102, and a target LCD monitor 103. The color deviation display adjustment terminal 101 can be a terminal device configured with a color deviation display adjustment system, including but not limited to a laptop computer, a tablet computer, a personal digital assistant (PDA), a PAD, a desktop computer, etc. with local computing capabilities; the color deviation display adjustment system can be implemented in the form of a target client, and the target client can be a video client, an instant messaging client, a browser client, etc. that support color deviation display adjustment; the color deviation display adjustment terminal 101 can communicate with the information collection terminal 102 through a network, which can include but not limited to: a wired network and a wireless network. Among them, the wired network includes: a local area network, a metropolitan area network, and a wide area network, and the wireless network includes: Bluetooth, WIFI, and other networks that implement wireless communication. The above-mentioned color deviation display adjustment terminal 101 can include but not limited to a human-computer interaction screen, a processor, and a memory. The above-mentioned human-computer interaction screen can be used to display the image of the monitor during the color deviation display adjustment process. The above-mentioned processor can be used to respond to human-computer interaction operations, execute corresponding operations, or generate corresponding instructions.

[0058] As an optional method, the information collection terminal 102 and the target LCD monitor 103 can be arranged opposite to each other to collect the color values corresponding to each pixel point in the target LCD monitor 103 through the information collection terminal 102. The information collection terminal 102 can include, for example: an imaging colorimeter, a spectrophotometer, a color analyzer, a spectral radiometer, a color calibrator. Exemplarily, an imaging colorimeter is a precision instrument dedicated to measuring and analyzing the color characteristics of a display device. It captures the image of the display device and extracts the color information of each pixel from it, thereby achieving precise measurement of the color performance of the display device; a spectrophotometer can measure the spectral distribution and calculate the color value based on this; a color analyzer combines spectral measurement and other sensor technologies and can provide high-precision color measurement. Some advanced models can be directly connected to a computer and have the function of automatic measurement; a spectral radiometer can measure the absolute spectral power distribution of a light source and can be used to calculate color coordinates; a color calibrator can help adjust the color of the monitor and can also measure the current display state. A color calibrator usually includes a small probe that can be placed on the screen to measure the color output.

[0059] As an optional method, the above-mentioned color deviation display adjustment terminal 101 can also be a server, which can be a single server, a server cluster composed of multiple servers, or a cloud server. The above is only an example, and this embodiment does not make any limitations in this regard.

[0060] As an alternative, the following steps of the color deviation display adjustment method applied to the LCD monitor can be executed on the color deviation display adjustment terminal 101:

[0061] Obtain the color values corresponding to each pixel point in the target LCD monitor;

[0062] Compare the color values corresponding to each pixel point with the preset standard color values, and determine multiple color deviation pixel point regions according to the comparison results;

[0063] Analyze the area, edge shape, and color change of each color deviation pixel point region, and obtain the first pixel point region corresponding to the hardware defect according to the analysis results;

[0064] Based on the first pixel point region, perform color deviation display adjustment on the target LCD monitor.

[0065] Based on the above method, comparing the color values corresponding to each pixel point with the preset standard color values and determining multiple color deviation pixel point regions according to the comparison results can identify the pixel points with color deviation, ensure the accuracy of the monitor color, and help to detect and solve the color deviation problem in a timely manner; because the characteristics of software defects and hardware defects in terms of area, edge shape, and color change are different, the area, edge shape, and color change of each color deviation pixel point region can be analyzed to distinguish the first pixel point region corresponding to the hardware defect, providing clear guidance for repair or replacement, thereby improving the accuracy of color deviation adjustment and ensuring that the monitor resumes normal color display.

[0066] As an alternative example, the execution subject of the above color deviation display adjustment method applied to the LCD monitor is not limited in this embodiment. The above color deviation display adjustment method applied to the LCD monitor can be executed on the color deviation display adjustment terminal 101. For example, when the color deviation display adjustment terminal 101 is a desktop computer, some or all of the steps of the above color deviation display adjustment method applied to the LCD monitor can be executed on the desktop computer.

[0067] The above part introduces the content of the exemplary implementation environment of applying the technical solution of the present application. Next, the color deviation display adjustment method applied to the LCD monitor of the present application will be continued to be introduced.

[0068] To solve the problem of how to improve the accuracy of color deviation adjustment in the prior art, the embodiments of the present application respectively propose a color deviation display adjustment method applied to the LCD monitor, a color deviation display adjustment system applied to the LCD monitor, an electronic device, a computer-readable storage medium, and a computer program product. These embodiments will be described in detail below.

[0069] Please refer to Figure 2 ,Figure 2 The flowchart of a color deviation display adjustment method applied to an LCD monitor provided by an embodiment of the present invention. This method can be applied to Figure 1 the implementation environment shown. It should be understood that this method can also be applicable to other exemplary implementation environments and be specifically executed by devices in other implementation environments. This embodiment does not limit the implementation environment applicable to this method.

[0070] As Figure 2 shown, in an exemplary embodiment, the color deviation display adjustment method applied to an LCD monitor at least includes steps S210 to S240, which are introduced in detail as follows:

[0071] In step S210, obtain the color values corresponding to each pixel point in the target LCD monitor.

[0072] Among them, the color value refers to the numerical value representing the color of a certain pixel in a digital image. Different color models use different numerical combinations to represent colors. The color models can include RGB (Red, Green, Blue), HSV (Hue, Saturation, Value), etc.

[0073] Exemplarily, RGB is one of the most commonly used color models, mainly used in display devices such as televisions and computer monitors. In the RGB model, colors are composed of different intensity combinations of three primary colors: Red, Green, and Blue. The intensity of each color is usually represented by an 8-bit binary number, with a value range from 0 to 255, which means that each color channel can have 256 different intensity levels.

[0074] Exemplarily, the HSV color model emphasizes the intuitive perception of colors and divides colors into three main parts: Hue, Saturation, and Value. Hue represents the type of color, usually represented by an angle from 0 to 360 degrees; Saturation represents the purity of the color, with a range from 0 to 100%, and the color is gray when the saturation is 0; Value represents the brightness of the color, with a range from 0 to 100%, and the color is black when the value is 0.

[0075] Among them, any one of an imaging colorimeter, a spectrophotometer, a color analyzer, a spectral radiometer, and a color calibrator can be selected to obtain the color values corresponding to each pixel point in the target LCD monitor.

[0076] In step S220, compare the color values corresponding to each pixel point with a preset standard color value, and determine multiple color deviation pixel point regions according to the comparison result.

[0077] Among them, the standard color value can be the standard value provided by the display manufacturer; it can also be the standard color value defined by the international standards organization; it can also be a user-defined color value for specific application requirements.

[0078] Among them, when comparing the color value corresponding to each pixel with the preset standard color value, the Euclidean distance or the color difference formula recommended by the International Commission on Illumination can be used to determine the comparison result of each pixel. According to the comparison result, if the difference between the color value of a certain pixel and the standard color value exceeds a predetermined threshold, it is considered that the pixel has a color deviation. Mark all the color-deviated pixel points to form a color-deviated pixel point area.

[0079] In step S230, analyze the area, edge shape, and color change of each of the color-deviated pixel point areas, and obtain the first pixel point area corresponding to the hardware defect according to the analysis result.

[0080] Among them, when adjusting the color deviation of the display, there may be a pixel point area where the color cannot be corrected due to hardware defects. It is necessary to analyze the distinguishing performance characteristics between software defects and non-adjustable color-deviated pixel points, and obtain the pixel point area that requires manual intervention and repair, so as to realize the color deviation display adjustment of the LCD display combining hardware and software.

[0081] Among them, analyzing the area of the color-deviated pixel point area mainly involves calculating the area of each color-deviated area and then comparing it with the panel area of the target LCD display. This can be achieved by counting the number of pixels in the color-deviated area or using the area measurement tool provided by image processing software.

[0082] Among them, when analyzing the edge shape of the color-deviated pixel point area, an edge detection algorithm can be used to identify the boundary of the color-deviated area, which helps to analyze the shape characteristics of the color-deviated area. Analyzing the edge shape of the color-deviated area includes, but is not limited to: regularity, checking whether the edge of the color-deviated area is smooth, regular or irregular; geometric features, measuring geometric parameters such as the perimeter and diameter of the color-deviated area; directionality, observing whether the color-deviated area expands along a certain direction.

[0083] Among them, when analyzing the color change of the color-deviated pixel point area, it is mainly to analyze the color change trend within the color-deviated area: uniformity, checking whether the color within the color-deviated area is uniform, or whether there is a gradient or spot; color distribution, counting the proportion of different colors within the color-deviated area and analyzing whether there is a specific color concentration phenomenon.

[0084] Among them, according to the above analysis results, the causes of color deviation and the corresponding hardware defects can be preliminarily obtained: isolated points or spots, if the color deviation is manifested as isolated points or small-scale spots, it may be a pixel defect (such as a dead point, a hot spot); regular shape, if the color deviation area presents a regular shape (such as a straight line, a rectangle), it may be a problem with the signal line or circuit board; irregular shape, if the color deviation area presents an irregular shape and the edges are blurred, it may be a problem with uneven backlight or uneven distribution of liquid crystal materials; color gradient, if the color deviation area shows a color gradient, it may be a problem with the coating or film layer of the display panel. For example, if multiple isolated points or spots are found to be concentrated in a certain area, and the color differences of these points are significant, then the area where these points are located is likely to be the area corresponding to the hardware defect.

[0085] In step S240, color shift display adjustment is performed on the target LCD display based on the first pixel point area.

[0086] Among them, based on the analysis results of the color-shifted pixel area, corresponding measures can be taken to adjust the display, for example: using the monitor's built-in calibration function to recalibrate the color; if the problem is caused by a hardware defect, it may be necessary to repair or replace related hardware components for the first pixel area, and then use color management tools to adjust the color profile at the software level.

[0087] It can be seen from the above steps S210 to S240 that the solution proposed in this embodiment compares the color value corresponding to each pixel with the preset standard color value, and determines multiple color-deviant pixel areas based on the comparison results, so as to identify pixels with color deviation, ensure the accuracy of the display color, and help to promptly discover and solve the color deviation problem; because software defects and hardware defects differ in the characteristics of area, edge shape, and color change, the area, edge shape, and color change of each color-deviant pixel area can be analyzed to distinguish the first pixel area corresponding to the hardware defect, thereby providing clear guidance for repair or replacement, thereby improving the accuracy of color deviation adjustment and ensuring that the display returns to normal color.

[0088] In one embodiment of the present application, the step of obtaining the color value corresponding to each pixel in the target LCD display includes:

[0089] Starting a preset display measurement program to make the target LCD display display a plurality of color samples;

[0090] When the target LCD display displays a plurality of color samples, the reflection spectrum of each color sample corresponding to each pixel point in the target LCD display is obtained by a preset colorimeter, and the color value is obtained according to the reflection spectrum.

[0091] Exemplarily, place the LCD monitor in a dark room, keep the light stable, turn on the LCD monitor and preheat it for 30 minutes to ensure that the screen reaches a stable state and reduce color deviation caused by temperature changes. Connect the imaging colorimeter to the computer, install the calibration software attached to the colorimeter, and use a bracket to align the colorimeter with the center of the LCD monitor to ensure that sufficient measurement points are covered. Start the monitor measurement program, and the monitor will automatically display a series of color samples (such as pure white, pure red, pure green, pure blue, and grayscale images). The colorimeter will sequentially measure the reflection spectra of these color samples at each measurement point of the monitor (equivalent to each pixel point in the monitor), record the spectral data and transmit it to the software to obtain the color values of each pixel point.

[0092] In an embodiment of the present application, the color value includes a hue value, the standard color value includes a standard hue value, and the comparing the color values corresponding to the respective pixel points with a preset standard color value and determining a plurality of color deviation pixel point regions according to the comparison result includes:

[0093] Comparing the hue value corresponding to each pixel point with the standard hue value to obtain the color deviation degree of each pixel point, and the color deviation degree is used to indicate the difference between the hue value and the standard hue value;

[0094] When the color deviation degree is greater than a preset color deviation degree threshold, the pixel point is used as a color deviation pixel point to obtain the plurality of color deviation pixel point regions.

[0095] Among them, the LCD display screen mainly includes a panel, a backlight, an LCD driving and control circuit, a liquid crystal module frame, etc. The LCD panel itself does not have a light-emitting characteristic. Uniform light is generated by the backlight and input into the panel. The panel receives the electrical signal from the main control circuit and drives the liquid crystal molecules. The liquid crystal molecules will exhibit different light transmittances after being driven by the electrical signal, thereby controlling the light intensity transmitted through each liquid crystal molecule region. Then, the white light is selectively transmitted through the color filter to form light of the three primary colors of red, green, and blue. The light intensity mixing ratio of the three primary colors is adjusted by the liquid crystal molecules to achieve the display of different colors. The manufacturing process of the LCD display screen is very complex, including stages such as photolithography, alignment layer arrangement, and glass cell processing. Due to the existence of environmental factors, temperature and humidity factors, and human interference factors during the liquid crystal panel processing, almost every panel has defects in the production of the liquid crystal panel, resulting in color deviation. Therefore, when measuring the color deviation of the LCD monitor, first evaluate the pixel points that need to correct the color, use a colorimeter to obtain the hue value of each pixel point in the HSV color space. When there is a large difference from the standard hue value in the ICC (International Color Consortium) profile, it indicates that the pixel point has a color deviation and needs color correction.

[0096] Exemplarily, the representation method of the color deviation degree of each pixel point can be:

[0097] S i = |H i - H i ′ |

[0098] Wherein, S i represents the color deviation degree of the i-th pixel point; H i represents the hue value of the i-th pixel point; H i ′ represents the standard hue value corresponding to the i-th pixel point.

[0099] Wherein, |H i - H i ′ | represents the difference between the hue value in the actual display of the i-th pixel point and the standard hue value. The greater the difference, the greater the color deviation degree of the pixel point.

[0100] Wherein, the greater the color deviation degree, the more color deviation exists in the pixel point, and color correction is required.

[0101] Exemplarily, pixel points with a color deviation degree exceeding the preset color deviation degree threshold of 0.01 are put into a set, and multiple color deviation pixel point regions are formed by connecting adjacent pixel points in the color deviation set.

[0102] In this embodiment, by comparing the hue value corresponding to each pixel point with the standard hue value, the pixel points that need color correction can be accurately found, rather than blindly adjusting the entire display area. This can effectively improve the pertinence and effectiveness of color correction. Only the pixel points with color deviation are processed, avoiding the influence on the normal display area, reducing the false alarm rate, and maintaining the color accuracy of the non-color deviation area. The colorimeter can provide high-precision color measurement data, especially the hue value in the HSV color space, which makes the subsequent color deviation analysis more reliable. The hue value (Hue) in the HSV color space directly reflects the basic attributes of the color.

[0103] In an embodiment of the present application, analyzing the area, edge shape, and color change of each of the color deviation pixel point regions, and obtaining a first pixel point region corresponding to the hardware defect according to the analysis result includes:

[0104] Analyzing the color deviation distribution of the target LCD monitor according to the area of each color deviation region, and obtaining the non-adjustability of each color deviation region, where the non-adjustability is used to indicate the possibility that each color deviation region cannot be adjusted for color deviation through software;

[0105] Based on the edge pixel points within each color deviation region and the adjacent pixel points of the edge pixel points, obtain the edge features of each color deviation region, where the edge features are used to indicate the edge shape of each color deviation region;

[0106] Based on the color deviation degrees of the pixel points within the color deviation region and the color deviation degrees of the neighboring pixel points of the pixel points, obtain the defect manifestation degrees corresponding to the color changes of each pixel point;

[0107] Based on the defect manifestation degrees of each pixel point and the edge features of each color deviation region, obtain the defect manifestation degrees of each color deviation region;

[0108] When the defect manifestation degree of the color deviation region is greater than a preset defect manifestation degree threshold, use the color deviation region as the first pixel point region.

[0109] In an embodiment of the present application, the analyzing the color deviation distribution of the target LCD monitor according to the areas of the color deviation regions to obtain the non-adjustability of each color deviation region includes:

[0110] Obtain the number of pixel points within the color deviation region;

[0111] Based on the number of pixel points, obtain the area of the color deviation region;

[0112] Compare the area of the color deviation region with the panel area of the target LCD monitor to obtain an area comparison result;

[0113] Based on the color deviation degrees of the pixel points within the color deviation region, obtain the average color deviation degree;

[0114] Based on the area comparison result and the average color deviation degree, obtain the non-adjustability of each color deviation region.

[0115] Among them, the pixel points with color deviation are caused by software defects and hardware defects, and corresponding treatments need to be carried out separately. Among them, the color deviation pixel points caused by software defects can be effectively adjusted in color output and the color deviation can be corrected through a color calibration tool; while for the pixel points where the color deviation still exists or can only be partially improved after software correction, they are related to hardware defects (such as quality defects of the liquid crystal panel, backlight non-uniformity or internal circuit problems), and it is necessary to check and repair the display materials of the corresponding pixel points. To prevent that when performing color correction on the display, due to accidental factors, the color output happens to be the same as the standard color after improvement, while the hardware defect still exists, and there will be a color display problem during subsequent user use, it is necessary to distinguish these two types of color deviation problems when measuring the color difference to ensure that the displays with color display defects do not flow to customers.

[0116] Among them, the color deviation caused by software defects usually manifests as a large - area shift in the color of the entire screen, and calibration software can be used to effectively adjust the color output. The color deviation caused by hardware defects appears as isolated pixel points in local areas. By analyzing the color deviation distribution on the LCD monitor panel, the non - adjustability of the monitor's color deviation can be obtained. When the proportion of the pixel point area with color deviation in the overall monitor panel is smaller, it indicates that this color deviation is more likely to be caused by hardware defects.

[0117] Exemplarily, the way to represent the non - adjustability of the color - deviation area can be:

[0118]

[0119] Among them, X j represents the non - adjustability of the j - th color - deviation area; A j represents the area of the j - th color - deviation area, which is represented by the number of pixel points in this area; A represents the panel area of the monitor; exp represents the exponential function with the natural constant e as the base; S j represents the average value of the color - deviation degrees of all pixel points in the j - th color - deviation area. The larger this value is, the more obvious the color deviation in this area is, and the greater the non - adjustability of software correction.

[0120] Among them, is the result of the area ratio comparison, representing the proportion of the j - th area with color deviation in the panel area of the entire LCD monitor. The color deviation caused by software defects often appears in patches or as a whole, and the area of the color deviation is relatively large. So, the smaller this formula is, the greater its non - adjustability.

[0121] Among them, the greater the non - adjustability, the greater the possibility that this area has a hardware defect; the smaller the non - adjustability, the smaller the possibility that this area has a hardware defect.

[0122] In this embodiment, converting the number of pixel points into an area enables the quantification of the severity of the color - deviation problem. Area is a more intuitive measurement unit, facilitating understanding and communication. The calculation of the area provides a unified scale for subsequent comparisons, enabling color - deviation areas of different sizes to be compared. By calculating the proportion of the color - deviation area in the total panel area, the proportion of the color - deviation problem in the entire display area can be evaluated, thereby determining the severity of the color - deviation problem. The average value of the color - deviation degree can also reflect the uniformity within the color - deviation area, helping to further analyze the pattern of the color deviation. Combining the area ratio comparison result and the average value of the color - deviation degree can comprehensively evaluate the non - adjustability of the color - deviation area. This helps to distinguish which color - deviation problems can be solved by software correction and which may require hardware repair or replacement.

[0123] In an embodiment of the present application, the adjacent pixel points include a left adjacent pixel point and a right adjacent pixel point. Obtaining the edge feature of each color deviation region according to the edge pixel points in each color deviation region and the adjacent pixel points of the edge pixel points includes:

[0124] Obtain the number of the edge pixel points in the color deviation region, the first connection direction angle between the edge pixel point and the left adjacent pixel point, and the second connection direction angle between the edge pixel point and the right adjacent pixel point;

[0125] Obtain the direction difference degree between the left adjacent pixel point and the right adjacent pixel point according to the number of the edge pixel points, the first connection direction angle, and the second connection direction angle;

[0126] Based on the non-adjustability of each color deviation region and the direction difference degree, obtain the edge feature of each color deviation region.

[0127] After obtaining the non-adjustability of each color deviation region in the display, to prevent the possibility of similar manifestations in the color deviation regions caused by hardware defects and software defects, it is necessary to further judge the manifestation characteristics of the color deviation regions, observe the shapes of the color deviation regions formed by the two. The edge of the color deviation region caused by hardware defects is a straight line, while the edge of the color deviation region of software defects has a certain curvature. If the edge pixel points are straight lines, then this region may be caused by hardware defects. The edges of the color deviation regions caused by hardware defects may have a perpendicular relationship, and the edge pixel points forming a right angle with the directions of the left and right adjacent edge pixel points are not considered.

[0128] Exemplarily, the representation method of the edge feature of the color deviation region can be:

[0129]

[0130] where B j represents the edge feature of the j-th color deviation region; X j represents the non-adjustability of the j-th color deviation region; K represents the number of edge pixel points in the color deviation region; l j,k represents the first connection direction angle between the k-th edge pixel point in the j-th color deviation region and the left adjacent pixel point; r j,k represents the second connection direction angle between the k-th edge pixel point in the j-th color deviation region and the right adjacent pixel point; exp represents the exponential function with the natural constant e as the base.

[0131] where It represents the degree of directional difference between the left adjacent pixel and the right adjacent pixel of all edge pixels in the j-th color deviation region. When the degree of directional difference is smaller, it indicates that the edge pixels in the color deviation region form a straighter line.

[0132] Among them, the larger the edge feature, the greater the possibility that the region is a hardware defect region.

[0133] In this embodiment, by calculating the number of edge pixels in the color deviation region, the complexity of the boundary of the color deviation region can be understood. The more edge pixels there are, the more complex the boundary of the color deviation region is. By calculating the connection direction angles between the edge pixels and their left and right adjacent pixels, the understanding of the edge feature can be further refined. The difference in angles can reveal the irregularity degree of the boundary of the color deviation region. The calculation of the first connection direction angle and the second connection direction angle helps to identify the directional change trend of the edge of the color deviation region, so as to judge whether the color deviation region presents a certain specific shape or pattern.

[0134] In an embodiment of the present application, obtaining the defect manifestation degree corresponding to the color change of each pixel point according to the color deviation degree of each pixel point in the color deviation region and the color deviation degree of the neighboring pixel points of the pixel point includes:

[0135] According to the color deviation degree of each pixel point in the color deviation region and the color deviation degree of the neighboring pixel points of the pixel point, obtain the degree of difference between the pixel point and each neighboring pixel point;

[0136] According to the degree of difference between the pixel point and each neighboring pixel point, obtain the defect manifestation degree corresponding to the color change of each pixel point.

[0137] Among them, after judging the entire color deviation region, due to the differences between the internal pixel points of the color deviation region caused by software defects and hardware defects, it is necessary to further judge each pixel point in the region. The pixel points in the color deviation region of software defects have continuous color changes, while the pixel points in the color deviation region of hardware defects are often known in color and mostly exist discontinuously and isolatedly.

[0138] Exemplarily, the representation method of the defect manifestation degree of a pixel point can be:

[0139]

[0140] Among them, Q j,o represents the defect manifestation degree of the o-th pixel point in the j-th color deviation region; N represents the eight neighboring pixels of each pixel point; S j,o represents the color deviation degree of the o-th pixel point in the j-th color deviation region; S j,o,n represents the color deviation degree of the n-th pixel point in the eight neighboring pixels of the o-th pixel point in the j-th color deviation region.

[0141] Among them, represents the degree of difference in color deviation between the o-th pixel in the j-th color deviation region and the pixels in its eight-neighbor region. There are differences in the color deviation degrees between each pixel in a large area caused by software defects and the pixels in its eight-neighbor region, but these differences are small and gradually changing. However, there are large color differences between each pixel in the color deviation region caused by hardware defects and the pixels in its eight-neighbor region, or the pixels with hardware defects are all edge pixels, and there are also large color differences with the surrounding region, and the differences in color deviation degrees are large. Therefore, when this formula is larger, the defect manifestation degree of this pixel is greater.

[0142] Among them, when the defect manifestation degree is greater, it means that the pixel is more likely to have color deviation due to hardware defects.

[0143] Exemplarily, according to the defect manifestation degree of each pixel in each color deviation region, the defective pixel region of the final LCD monitor is confirmed. When the consistency degree of the defect manifestation degrees of each pixel in the color deviation region is high and all are large, this region may belong to the defective pixel region in the production of the LCD monitor. Among them, the representation method of the defect manifestation degree of the color deviation region can be:

[0144] P j = Q j × B j

[0145] Among them, P j represents the defect manifestation degree of the j-th color deviation region; Q j represents the average value of the defect manifestation degrees of all pixels in the j-th color deviation region. When the defect manifestation degrees of all pixels in this region are large, the defect manifestation degree of this color deviation region is greater; B j represents the edge feature of the j-th color deviation region. When this value is larger, it indicates that the edge of this color deviation region more conforms to the characteristics of hardware defects, and its defect manifestation degree is greater.

[0146] Among them, when the defect manifestation degree of the color deviation region is greater, it means that this color deviation region is more likely to have color deviation caused by hardware defects.

[0147] Exemplarily, when the defect manifestation degree of the color deviation region exceeds the preset defect manifestation degree threshold of 0.7, this color deviation region is used as the first pixel region.

[0148] In an embodiment of the present application, the color deviation display adjustment for the target LCD monitor based on the first pixel region includes:

[0149] Giving a maintenance prompt for the hardware corresponding to the first pixel region;

[0150] After the repair of the first pixel point area, the target LCD monitor is detected by a pre-set colorimeter to obtain the second pixel point area corresponding to the software defect;

[0151] Based on the pre-generated color correction data, color deviation display adjustment is performed on the second pixel point area to correct the color output of the target LCD monitor.

[0152] Exemplarily, after a repair prompt is given for the hardware corresponding to the first pixel point area and professionals are notified to inspect and repair the circuits, transistors and other materials in the first pixel point area, the monitor is detected and adjusted again using an imaging colorimeter to obtain the second pixel point area corresponding to the software defect. At the same time, the software supporting the colorimeter generates an ICC profile containing color correction data. The generated ICC profile is applied to the system as the default color profile of the monitor to correct the color output of the monitor to meet the standards, and finally an LCD monitor with color deviation adjusted is obtained.

[0158] A color deviation display adjustment unit 304, configured to perform color deviation display adjustment on the target LCD monitor based on the first pixel point area.

[0159] In the exemplary color deviation display adjustment system applied to an LCD monitor, the color values corresponding to each pixel are compared with preset standard color values, and multiple color deviation pixel regions are determined according to the comparison results, enabling the identification of pixels with color deviation, ensuring the color accuracy of the monitor, and helping to promptly detect and solve color deviation problems. Since the characteristics of software defects and hardware defects differ in terms of area, edge shape, and color change, it is possible to analyze the area, edge shape, and color change of each color deviation pixel region to distinguish the first pixel region corresponding to the hardware defect, providing clear guidance for repair or replacement, thereby improving the accuracy of color deviation adjustment and ensuring that the monitor resumes normal color display.
