Description

Technical Field

[0001] The present invention relates to the technical field of display devices, and in particular to a color shift display adjustment method, device and system applied to LCD displays. Background Art

[0002] LCD displays (Liquid Crystal Displays) often have color shifts during the manufacturing process due to cost control, material differences, and production process, which leads to deviations between the display effect and the actual color. Adjusting the color shift of LCD displays is an important step to ensure accurate color reproduction. Color shift adjustment usually requires professional equipment such as a colorimeter. Combining hardware and software for color calibration can significantly improve color performance, thereby providing users with a more realistic and accurate visual experience.

[0003] In the existing color shift adjustment method, a colorimeter is usually used to measure the color shift pixels of the LCD display and generate a configuration file containing color correction data to correct the color output of the display. The colorimeter projects a color sample on the display and records the reflected spectral data. However, when the colorimeter performs color evaluation, the pixel area showing color shift may also be abnormal color caused by problems with the liquid crystal layer, thin-film transistors, or backlight, and these defective areas will be mistakenly identified as adjustable areas, thereby reducing the accuracy of color shift adjustment.

[0056] The following specifically describes a method, device and system for adjusting color shift display of an LCD display provided by the present invention in conjunction with the accompanying drawings.

[0057] See also Figure 1 , Figure 1 A schematic diagram of an implementation environment of a color shift display adjustment method for an LCD display provided by an embodiment of the present invention. Figure 1As shown, the implementation environment includes a color deviation display adjustment terminal 101, an information collection terminal 102, and a target LCD display 103. The color deviation display adjustment terminal 101 can be a terminal device equipped with a color deviation display adjustment system, including but not limited to a laptop computer, a tablet computer, a handheld computer, 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 supports color deviation display adjustment; the color deviation display adjustment terminal 101 can, but is not limited to, communicate with the information collection terminal 102 through a network, and the above network can include but is not limited to: a wired network, a wireless network, wherein 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 color deviation display adjustment terminal 101 can, but is not limited to, include a human-computer interaction screen, a processor, and a memory. The above human-computer interaction screen can, but is not limited to, be used to display the image of the display during the color deviation display adjustment process. The above processor can, but is not limited to, be used to respond to human-computer interaction operations, perform corresponding operations, or generate corresponding instructions.

[0058] As an optional method, the information collection terminal 102 can be arranged relative to the target LCD display 103, so that the color value corresponding to each pixel in the target LCD display 103 can be collected through the information collection terminal 102. The information collection terminal 102 may include, for example: an imaging colorimeter, a spectrophotometer, a color analyzer, a spectroradiometer, and a color calibrator. For example, an imaging colorimeter is a precision instrument specifically used to measure and analyze the color characteristics of a display device. It captures an image of the display device and extracts the color information of each pixel therefrom, thereby achieving accurate measurement of the color performance of the display device; a spectrophotometer can measure the spectral distribution and calculate the color value based on it; a color analyzer combines spectral measurement and other sensor technologies to provide high-precision color measurement. Some advanced models can be directly connected to a computer and have the function of automated measurement; a spectroradiometer 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 display and can also measure the current display status. A color calibrator usually includes a small probe that can be placed on the screen to measure the color output.

[0059] As an optional manner, the color deviation display adjustment terminal 101 may also be a server, which may 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 limitation to this.

[0060] As an optional manner, the following steps of the color shift display adjustment method applied to the LCD display may be performed on the color shift display adjustment terminal 101:

[0061] Get the color value corresponding to each pixel in the target LCD display;

[0062] Comparing the color value corresponding to each pixel with a preset standard color value, and determining a plurality of color-shifted pixel regions according to the comparison result;

[0063] Analyze the area, edge shape, and color change of each of the color-shifted pixel regions, and obtain a first pixel region corresponding to the hardware defect according to the analysis result;

[0064] Based on the first pixel point area, color shift display adjustment is performed on the target LCD display.

[0065] Based on the above method, the color value corresponding to each pixel is compared with the preset standard color value, and multiple color-deviant pixel areas are determined according to the comparison results. The pixels with color deviation can be identified, the accuracy of the display color can be ensured, and it is helpful 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, and the first pixel area corresponding to the hardware defect can be distinguished, providing clear guidance for repair or replacement, thereby improving the accuracy of color deviation adjustment and ensuring that the display returns to normal color.

[0066] As an optional example, this embodiment does not limit the execution subject of the above-mentioned color deviation display adjustment method applied to the LCD display. The above-mentioned color deviation display adjustment method applied to the LCD display 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 steps of the above-mentioned color deviation display adjustment method applied to the LCD display can be executed on the desktop computer.

[0067] The above section introduces the contents of an exemplary implementation environment for applying the technical solution of the present application. Next, the present application will continue to introduce the color shift display adjustment method applied to an LCD display.

[0068] In order 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 an LCD display, a color deviation display adjustment system applied to an LCD display, an electronic device, a computer-readable storage medium and a computer program product. These embodiments will be described in detail below.

[0069] See also Figure 2 , Figure 2 A flow chart of a method for adjusting color shift display applied to an LCD display provided by an embodiment of the present invention. The method can be applied to Figure 1 It should be understood that the method can also be applied to other exemplary implementation environments and specifically executed by devices in other implementation environments, and this embodiment does not limit the implementation environment to which the method is applicable.

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

[0071] In step S210, the color value corresponding to each pixel in the target LCD display is obtained.

[0072] The color value refers to the numerical value representing the color of a pixel in a digital image. Different color models use different numerical combinations to represent colors, and color models may include RGB (red, green, and blue), HSV (hue, saturation, and value), etc.

[0073] For example, RGB is one of the most commonly used color models, mainly used in display devices such as televisions, computer monitors, etc. In the RGB model, colors are composed of different intensities of three basic colors: red, green, and blue. The intensity of each color is usually represented by an 8-bit binary number ranging from 0 to 255, which means that each color channel can have 256 different intensity levels.

[0074] For example, the HSV color model emphasizes the intuitive perception of color and divides color into three main parts: Hue, Saturation, and Value. Hue indicates the type of color, usually expressed as an angle from 0 to 360 degrees; Saturation indicates the purity of the color, ranging from 0 to 100%, and the color is gray when the saturation is 0; Value indicates the brightness of the color, ranging 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 spectroradiometer, and a color calibrator can be selected to obtain the color value corresponding to each pixel point in the target LCD display.

[0076] In step S220, the color value corresponding to each pixel is compared with a preset standard color value, and a plurality of color-shifted pixel regions are determined according to the comparison result.

[0077] The standard color value may be a standard value provided by a display manufacturer; may be a standard color value defined by an international standards organization; or may be a user-defined color value for specific application requirements.

[0078] When the color value corresponding to each pixel is compared with the preset standard color value, the comparison result of each pixel can be determined by the Euclidean distance or the color difference formula recommended by the International Illumination Commission. According to the comparison result, if the difference between the color value of a pixel and the standard color value exceeds a predetermined threshold, it is considered that the pixel has color deviation. All color deviation pixels are marked to form a color deviation pixel area.

[0079] In step S230, the area, edge shape and color change of each color-shifted pixel region are analyzed, and the first pixel region corresponding to the hardware defect is obtained according to the analysis result.

[0080] Among them, when adjusting the color deviation of the display, there may be pixel areas where the color cannot be corrected due to hardware defects. It is necessary to analyze the different performance characteristics of software defects and unadjustable color deviation pixels, and obtain the pixel 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] The area of ​​the color-shifted pixel region is analyzed by calculating the area of ​​each color-shifted region 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-shifted region or using the area measurement tool provided by the image processing software.

[0082] Among them, the edge shape of the color-shifted pixel area is analyzed, and the edge detection algorithm can be used to identify the boundary of the color-shifted area, which is helpful to analyze the shape characteristics of the color-shifted area. The edge shape of the color-shifted area is analyzed, including but not limited to: regularity, checking whether the edge of the color-shifted area is smooth, regular or irregular; geometric features, measuring geometric parameters such as the perimeter and diameter of the color-shifted area; directionality, observing whether the color-shifted area extends in a certain direction.

[0083] Among them, the color change analysis of the color-shifted pixel area is mainly to analyze the color change trend in the color-shifted area: uniformity, check whether the color in the color-shifted area is uniform, or whether there is a gradient or spot; color distribution, count the proportion of different colors in the color-shifted area, and analyze 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 display in a dark room, keep the light stable, start the LCD display and preheat 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 that comes with the colorimeter, and use a bracket to align the colorimeter with the center of the LCD display to ensure that enough measurement points are covered. Start the display measurement program, and the display will automatically display a series of color samples (such as pure white, pure red, pure green, pure blue, and grayscale images). The colorimeter will measure the reflectance spectrum of these color samples at each measurement point of the display (equivalent to each pixel in the display) in turn, and record the spectral data and transmit it to the software to obtain the color value of each pixel.

[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 color value corresponding to each pixel is compared with a preset standard color value, and a plurality of color-shifted pixel regions are determined according to the comparison result, including:

[0093] Comparing the hue value corresponding to each pixel with the standard hue value to obtain the color deviation of each pixel, where the color deviation 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 the panel, backlight source, LCD drive and control circuit, liquid crystal module frame, etc. The LCD panel itself has the characteristics of luminescence. The uniform light is generated by the backlight source and input to the panel. The panel receives the electrical signal of the main control circuit and drives the liquid crystal molecules. The liquid crystal molecules will show different transmittances after being driven by the electrical signal, and then control the light intensity transmitted by each liquid crystal molecule area. Then the white light is selectively transmitted through the color filter to form 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 display different colors. The manufacturing process of the LCD display screen is very complicated, including photolithography, alignment layer arrangement and glass empty box processing. Due to the environmental factors, temperature and humidity factors, and human interference factors in the process of liquid crystal panel processing, almost every panel in the production of liquid crystal panels has defects, resulting in color deviation. Therefore, when measuring color deviation on an LCD display, first evaluate the pixels that need to be corrected, and use a colorimeter to obtain the hue value of each pixel in the HSV color space. If there is a large difference from the standard hue value in the ICC (International Color Consortium) profile, it means that the pixel has color deviation and needs color correction.

[0096] Exemplarily, the color deviation of each pixel may be expressed as follows:

[0097] S i =|H i -H i ′ |

[0098] Among them, S i Indicates the color deviation of the i-th pixel; H i Represents the hue value of the i-th pixel; H i ′ Indicates the standard hue value corresponding to the i-th pixel.

[0099] Among them, |H i -H i ′ | represents the difference between the hue value of the actual display of the i-th pixel and the standard hue value. The larger the difference, the greater the color deviation of the pixel.

[0100] The greater the color deviation, the more likely the pixel has color deviation and needs color correction.

[0101] Exemplarily, pixels whose color deviation exceeds a preset color deviation threshold of 0.01 are put into a set, and connected pixels in the color deviation set are grouped into a plurality of color deviation pixel regions.

[0102] In this embodiment, the hue value corresponding to each pixel is compared with the standard hue value, so that the pixel that needs color correction can be accurately found, instead of blindly adjusting the entire display area, which can effectively improve the pertinence and effectiveness of color correction. Only the pixels with color deviation are processed, which avoids the impact on the normal display area, reduces the false alarm rate, and maintains 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 properties of the color.

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

[0104] According to the area of ​​each color deviation region, the color deviation distribution of the target LCD display is analyzed to obtain the non-adjustability of each color deviation region, wherein the non-adjustability is used to indicate the possibility that the color deviation of each color deviation region cannot be adjusted by software;

[0105] Obtaining edge features of each color-shifted region according to edge pixels in each color-shifted region and adjacent pixels of the edge pixels, wherein the edge features are used to indicate edge shapes of each color-shifted region;

[0106] According to the color deviation degree of each pixel point in the color deviation area and the color deviation degree of the neighboring pixel points of the pixel point, the defect expression degree corresponding to the color change of each pixel point is obtained;

[0107] Obtaining the defect expression degree of each of the color deviation regions according to the defect expression degree of each of the pixel points and the edge features of each of the color deviation regions;

[0108] When the defect expression degree of the color deviation area is greater than a preset defect expression degree threshold, the color deviation area is used as the first pixel point area.

[0109] In one embodiment of the present application, analyzing the color shift distribution of the target LCD display according to the area of ​​each color shift region to obtain the non-adjustability of each color shift region includes:

[0110] Obtain the number of pixels in the color deviation area;

[0111] According to the number of the pixels, the area of ​​the color deviation region is obtained;

[0112] Comparing the area of ​​the color shift region with the panel area of ​​the target LCD display to obtain an area comparison result;

[0113] Obtaining a color deviation average value according to the color deviation of each pixel in the color deviation area;

[0114] The non-adjustability of each of the color deviation regions is obtained according to the area comparison result and the color deviation average.

[0115] Among them, pixels with color deviation are divided into those caused by software defects and those caused by hardware defects, and they need to be processed accordingly. For pixels with color deviation caused by software defects, the color output can be effectively adjusted and the color deviation can be corrected through color calibration tools; pixels where the color deviation still exists or can only be partially improved after software correction are related to hardware defects (such as quality defects of the LCD panel, backlight unevenness, or internal circuit problems), and the display materials of the corresponding pixels need to be inspected and repaired. In order to prevent the color output from being improved to the same color as the standard color due to accidental factors during color correction of the display, while the hardware defect still exists, and there will be color rendering problems when the user uses it later, it is necessary to distinguish between these two types of color deviation problems when measuring color difference to ensure that displays with color rendering defects will not be circulated to customers.

[0116] Color shift caused by software defects usually manifests as large-area color shift of the entire screen. Calibration software can be used to effectively adjust color output. Color shift caused by hardware defects manifests as isolated pixels in local areas. The color shift distribution of the LCD display panel is used to obtain the non-adjustability of the display color shift. The smaller the proportion of the pixel area with color shift in the overall display panel, the more likely the color shift is caused by hardware defects.

[0117] Exemplarily, the non-adjustability of the color shift region may be represented as follows:

[0118]

[0119] Among them, X j A represents the unadjustability of the jth color shift area; j represents the area of ​​the jth color deviation region, expressed by the number of pixels in the region; A represents the panel area of ​​the display; exp represents an exponential function with the natural constant e as the base; S j It represents the average color deviation of all pixels in the j-th color deviation area. The larger the value is, the more obvious the color deviation in this area is, and the greater the unadjustability of software correction is.

[0120] in, is the area comparison result, indicating the ratio of the j-th area producing color deviation to the panel area of ​​the entire LCD display. The color deviation of software defects often appears in patches or as a whole. The area occupied by the color deviation is large. The smaller this formula is, the greater its unadjustability is.

[0121] The greater the unadjustability, the greater the possibility that the region is a hardware defect; and the smaller the unadjustability, the smaller the possibility that the region is a hardware defect.

[0122] In this embodiment, the number of pixels is converted into area so that the severity of the color deviation problem can be quantified. Area is a more intuitive unit of measurement, which is easy to understand and communicate. The calculation of the area provides a unified scale for subsequent comparisons, so that color deviation areas of different sizes can be compared. By calculating the proportion of the area of ​​the color deviation area to the total panel area, the proportion of the color deviation problem in the entire display area can be evaluated, thereby judging the severity of the color deviation problem. The mean color deviation degree can also reflect the uniformity within the color deviation area, which helps to further analyze the color deviation pattern. Combining the area comparison results and the mean color deviation degree, the non-adjustability of the color deviation area can be comprehensively evaluated. This helps to distinguish which color deviation problems can be solved by software correction and which may require hardware repair or replacement.

[0123] In one embodiment of the present application, the adjacent pixel points include left adjacent pixel points and right adjacent pixel points, and the edge features of each color shift region are obtained according to the edge pixel points in each color shift region and the adjacent pixel points of the edge pixel points, including:

[0124] Acquire the number of edge pixels in the color deviation area, as well as the first line direction angle between the edge pixel and the left adjacent pixel, and the second line direction angle between the edge pixel and the right adjacent pixel;

[0125] Obtaining a degree of directional difference between the left adjacent pixel points and the right adjacent pixel points according to the number of the edge pixel points, the first connecting line direction angle, and the second connecting line direction angle;

[0126] Based on the non-adjustability of each of the color-shifted regions and the degree of directional difference, edge features of each of the color-shifted regions are obtained.

[0127] Among them, after obtaining the non-adjustability of each color deviation area in the display, in order to prevent the possibility of similar performance of the color deviation area caused by hardware defects and software defects, it is necessary to further judge the performance characteristics of the color deviation area and observe the shape of the color deviation area formed by the two. The edge of the color deviation area caused by hardware defects is a straight line, while the edge of the color deviation area caused by software defects has a certain curvature. If the edge pixel point is a straight line, then the area may be caused by hardware defects. The edge of the color deviation area caused by hardware defects may have a vertical relationship, and the edge pixel points that form a right angle with the direction of the left and right adjacent edge pixel points are not considered.

[0128] Exemplarily, the edge features of the color cast region may be represented as follows:

[0129]

[0130] Among them, B j represents the edge feature of the jth color shift region; X j represents the unadjustability of the jth color deviation area; K represents the number of edge pixels in the color deviation area; l j,k represents the first line direction angle between the kth edge pixel point and the left adjacent pixel point in the jth color deviation area; r j,k represents the direction angle of the second line between the kth edge pixel point and the right adjacent pixel point in the jth color shift area; exp represents an exponential function with the natural constant e as the base.

[0131] in, It represents the degree of directional difference between the left adjacent pixel points and the right adjacent pixel points of all edge pixel points in the j-th color shift area. The smaller the degree of directional difference is, the greater the degree to which the edge pixel points in the color shift area form a straight line.

[0132] The larger the edge feature, the greater the possibility that the area is a hardware defect area.

[0133] In this embodiment, by calculating the number of edge pixels in the color-shifted region, the complexity of the boundary of the color-shifted region can be understood. The more edge pixels there are, the more complex the boundary of the color-shifted region is. By calculating the direction angle of the connection between the edge pixel and its left and right adjacent pixels, the understanding of the edge features can be further refined. The difference in angles can reveal the degree of irregularity of the boundary of the color-shifted 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-shifted region, thereby determining whether the color-shifted region presents a certain specific shape or pattern.

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

[0135] Obtaining the degree of difference between the pixel and each of the neighboring pixels according to the degree of color deviation of each pixel in the color deviation area and the degree of color deviation of the neighboring pixels of the pixel;

[0136] According to the difference between the pixel point and each of the neighboring pixel points, the defect expression degree corresponding to the color change of each of the pixel points is obtained.

[0137] Among them, after judging the entire color deviation area, due to the differences between the internal pixels of the color deviation area caused by software defects and hardware defects, it is necessary to further judge each pixel in the area. The color deviation area of ​​software defects has continuous color changes between the pixels, while the color deviation area of ​​hardware defects often has known colors and mostly exists intermittently and isolatedly.

[0138] Exemplarily, the defect representation degree of a pixel point may be expressed as follows:

[0139]

[0140] Among them, Q j,o represents the defect expression degree of the oth pixel in the jth color deviation area; N represents the eight neighboring pixels of each pixel; S j,o represents the color deviation of the oth pixel in the jth color deviation area; S j,o,n Indicates the color deviation degree of the nth pixel in the eight-neighborhood of the oth pixel in the jth color deviation area.

[0141] in, It represents the degree of difference in color deviation between the oth pixel in the jth color deviation area and the pixels in the eight-neighborhood area. There is a difference in color deviation between each pixel in the large area caused by software defects and the pixels in the eight-neighborhood area, but they are all small and gradual. There is a large color difference between each pixel in the color deviation area caused by hardware defects and the pixels in the eight-neighborhood area, or the pixels with hardware defects are all edge pixels, and there is also a large color difference with the surrounding area. The difference in color deviation is large. Therefore, when the formula is larger, the defect expression degree of the pixel is greater.

[0142] Among them, the greater the defect expression, the more likely the pixel will have color deviation due to hardware defects.

[0143] For example, the defective pixel area of ​​the final LCD display is determined based on the defective expression degree of each pixel in each color deviation area. When the defective expression degree of each pixel in the color deviation area is highly consistent and large, the area may belong to the pixel area of ​​the LCD display production defect. The defective expression degree of the color deviation area can be expressed as:

[0144] P j =Q j ×B j

[0145] Among them, P j represents the defect expression degree of the jth color deviation area; Q j B represents the mean defect expression degree of all pixels in the jth color deviation area. When the defect expression degree of all pixels in the area is large, the defect expression degree of the color deviation area is large. j Represents the edge feature of the j-th color deviation area. The larger the value, the more the edge of the color deviation area conforms to the characteristics of the hardware defect, and the greater the defect expression degree.

[0146] The greater the defect expression degree of the color deviation area, the more likely the color deviation of the color deviation area is caused by hardware defects.

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

[0148] In one embodiment of the present application, the color shift display adjustment of the target LCD display based on the first pixel point area includes:

[0149] Providing maintenance prompts for the hardware corresponding to the first pixel area;

[0150] After the first pixel area is repaired, the target LCD display is tested by a preset colorimeter to obtain a second pixel area corresponding to the software defect;

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

[0152] Exemplarily, a maintenance prompt is given for the hardware corresponding to the first pixel area, and after notifying professionals to inspect and repair the circuits, transistors and other materials in the first pixel area, the imaging colorimeter is used again to detect and adjust the display to obtain the second pixel area corresponding to the software defect. At the same time, the colorimeter supporting software generates an ICC profile including color correction data. The generated ICC profile is applied to the system as the default color profile of the display, and the color output of the display is corrected to meet the standard, ultimately obtaining an LCD display with adjusted color deviation.

[0155] A color value acquisition unit 301 is used to acquire the color value corresponding to each pixel in the target LCD display;

[0156] A color value comparison unit 302 is used to compare the color value corresponding to each pixel with a preset standard color value, and determine a plurality of color-shifted pixel regions according to the comparison result;

[0157] The hardware defect analysis unit 303 is used to analyze the area, edge shape and color change of each color-shifted pixel region, and obtain a first pixel region corresponding to the hardware defect according to the analysis result;

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

[0159] In this exemplary color deviation display adjustment system applied to LCD displays, the color value corresponding to each pixel is compared with a preset standard color value, and multiple color deviation pixel areas are determined based on the comparison results. Pixels with color deviation can be identified, the accuracy of the display color can be ensured, and it is helpful to promptly discover and solve color deviation problems. 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 deviation pixel area can be analyzed, and the first pixel area corresponding to the hardware defect can be distinguished, providing clear guidance for repair or replacement, thereby improving the accuracy of color deviation adjustment and ensuring that the display returns to normal color.
