DETAILED DESCRIPTION

[0021] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0022] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with substantially the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there any limitation on the quantity and execution order.

[0023] Artificial Intelligence (AI) is the theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to achieve better results.

[0024] Machine learning (ML) is a multidisciplinary field that encompasses probability theory, statistics, approximation theory, convex analysis, and algorithmic complexity theory. It specifically studies how computers can simulate or implement human learning behaviors to acquire new knowledge or skills and reorganize existing knowledge sub-models to continuously improve their performance. Machine learning is at the core of artificial intelligence and the fundamental way to make computers intelligent. Its applications span all areas of AI.

[0025] A display device is an electronic output device used to convert electronic signals into visual images or text. It is widely used in terminal devices such as computers, televisions, and mobile phones. Its core function is to achieve visual presentation of information through various technical means (such as optical and electrical means).

[0026] Color Accuracy: refers to the degree of consistency between the colors presented by a display device or imaging system and the true or standard colors. It is one of the core indicators for measuring display quality.

[0027] Color Accuracy Testing: A testing process that evaluates a device's color reproduction capabilities using standardized methods to ensure it meets the requirements of a specific industry or application scenario. In this embodiment, the color accuracy test is used to determine the test score of the target display, thereby quantitatively evaluating the color accuracy of the target display.

[0028] In related technologies, color accuracy testing of display screens usually relies on the naked eye judgment of testers. However, different testers have different judgment criteria, resulting in different testers obtaining different results when judging the color accuracy of the same display screen. The test results are less consistent and less reliable.

[0029] In response to the above problems, the technical solution provided in the embodiments of the present application can realize automated color accuracy testing, and the final test results are highly interpretable, which not only improves the efficiency of color accuracy testing of display screens, but also obtains more accurate test results.

[0030] Figure 1 This is a schematic diagram of the implementation environment of a display color accuracy testing method provided in an embodiment of the present application, see Figure 1The implementation environment may include a test device 101 and an external image acquisition device 104 .

[0031] Testing device 101 is used to acquire data related to color accuracy testing and process the acquired data to determine a color accuracy test score, which is a measure of color accuracy. The data acquired by testing device 101 includes data related to the target display screen to be tested, data related to the environment in which the target display screen is located, and data related to external image acquisition device 104.

[0032] The external image acquisition device 104 is connected to the test device 101 via a wired network or a wireless network. The external image acquisition device 104 is used to capture the display content of the target display screen. In other words, the external image acquisition device 104 is equivalent to the "glasses" of the test device 101, enabling external observation of the target display screen. When testing the target display screen, the content acquisition side of the external image acquisition device 104 faces the target display screen, thereby capturing the display content of the target display screen. In addition, when performing color accuracy testing, the external image acquisition device 104 and the target display screen are adjacent but not close to each other to avoid damaging the target display screen. The distance between the external image acquisition device 104 and the target display screen is set by a technician based on actual conditions, and this embodiment of the application does not limit this.

[0033] After introducing the implementation environment of the embodiments of the present application, the application scenarios of the embodiments of the present application are described below. The technical solutions provided by the embodiments of the present application can be applied in the scenario of color accuracy testing of display screens of various types and sizes. By using the technical solutions provided by the embodiments of the present application, it is possible to implement automated color accuracy testing of display screens, directly obtain color accuracy test results, and the test process does not rely on the subjective evaluation of the tester, and the test results are highly accurate.

[0034] The following describes the display color accuracy testing method provided in the embodiment of the present application. Figure 2 This is a flow chart of a display color accuracy testing method provided by an embodiment of the present application, see Figure 2 Taking the execution subject as the test device as an example, the method includes the following steps.

[0035] 201. In response to a color accuracy test instruction for a target display screen, a test device obtains display screen information of the target display screen, environmental information of the environment in which the target display screen is located, and operating parameters of an external image acquisition device, and acquires display content of the target display screen through the external image acquisition device, where the external image acquisition device is adjacent to but not in contact with the target display screen.

[0036] Among them, the target display screen is the display screen to be tested for color accuracy. The color accuracy test instruction is triggered manually by the tester or automatically when certain conditions are met, and the embodiments of the present application are not limited to this. The display screen information includes information related to the target display screen, and the display screen information is crucial for determining the color accuracy of the target display screen. The environmental information includes information related to the environment in which the target display screen is located. The environmental information will affect the test results of the color accuracy test. In order to obtain more accurate test results, it is necessary to use the environmental information for calibration. The external image acquisition device is used to capture the display content of the target display screen, and the working parameters are used to describe the working conditions of the external image acquisition device. The working conditions of the external image acquisition device will also affect the final test results, so it is also necessary to use the working parameters for calibration. The display content is the content that needs to be displayed when the target display screen is subjected to the color accuracy test, and the display content is an image or video. In some embodiments, when the target display screen is subjected to the color accuracy test, the target display screen is connected to the test device, and the test device supplies power to the target display screen and provides the display content.

[0037] 202. The testing device determines a first color accuracy impact parameter of the target display screen based on the display screen information and the environmental information, where the first color accuracy impact parameter is used to indicate a degree of impact of the display screen information and the environmental information on color accuracy.

[0038] The first color accuracy impact parameter can reflect the combined impact of the target display screen itself and the surrounding environment on color accuracy.

[0039] 203. The testing device determines a second color accuracy influencing parameter of the target display screen based on the display screen information, the environmental information, and the operating parameters, where the second color accuracy influencing parameter is used to indicate the degree of influence of the display screen information, the environmental information, and the operating parameters on color accuracy.

[0040] The second color accuracy influencing parameter can reflect the combined influence of the target display screen itself, the surrounding environment, and the external image acquisition device on the color accuracy.

[0041] 204. The testing device determines a test score of the target display screen based on the first color accuracy influencing parameter, the second color accuracy influencing parameter, the display content, and standard color information of the display content, where the test score is used to represent color accuracy.

[0042] The test score is positively correlated with color accuracy, that is, the higher the test score, the higher the color accuracy; the lower the test score, the lower the color accuracy.

[0043] Through the technical solution provided by the embodiment of the present application, in response to a color accuracy test instruction for a target display screen, the display screen information of the target display screen, the environmental information of the environment in which the target display screen is located, and the working parameters of an external image acquisition device are obtained, and at the same time, the display content of the target display screen is acquired through the external image acquisition device. Based on the display screen information and the environmental information, a first color accuracy influencing parameter of the target display screen is determined, and the first color accuracy influencing parameter is used to eliminate the influence of the display screen itself and the environment on color accuracy. And based on the display screen information, the environmental information, and the working parameters, a second color accuracy influencing parameter of the target display screen is determined, and the second color accuracy influencing parameter is used to eliminate the influence of the external image acquisition device on color accuracy. The test score of the target display screen is determined based on the first color accuracy influencing parameter, the second color accuracy influencing parameter, the display content, and the standard color information of the display content, and the accuracy of the test score is relatively high.

[0044] The above steps 201-204 are a brief introduction to the display color accuracy test method provided by the embodiment of the present application. The following will combine some examples to more clearly illustrate the display color accuracy test method provided by the embodiment of the present application. Figure 3 Taking the execution subject as a test device as an example, the method includes the following steps.

[0045] 301. In response to a color accuracy test instruction for a target display screen, a test device obtains display screen information of the target display screen, environmental information of the environment in which the target display screen is located, and operating parameters of an external image acquisition device, and acquires display content of the target display screen through the external image acquisition device, where the external image acquisition device is adjacent to but not in contact with the target display screen.

[0046] The target display is the display to be tested for color accuracy, and may include a mobile phone display, laptop display, monitor, tablet display, or television display. The color accuracy test instruction is used to instruct a color accuracy test to be performed on the target display. It can be triggered manually by a tester or automatically when certain conditions are met, but this is not limited in the present embodiments. Display information includes information related to the target display, which is crucial for determining the color accuracy of the target display. Environmental information includes information related to the environment in which the target display is located. Environmental information can affect the test results of the color accuracy test, and to obtain more accurate test results, calibration is required using environmental information. An external image acquisition device is used to capture the display content of the target display. Operating parameters describe the operating conditions of the external image acquisition device, which can also affect the final test results. Therefore, calibration is also required using operating parameters. Display content is the content to be displayed on the target display during the color accuracy test, and can be an image or video. In some embodiments, when performing a color accuracy test on the target display, the target display is connected to a test device, which provides power to the target display and displays the content, enabling data exchange between the test device and the target display. In some embodiments, the connection between the target display screen and the test device can be achieved through a transmission device, that is, the target display screen is placed on the transmission device, and the transmission device can move the target display screen to the position where the external image acquisition device is located. At the same time, the connection between the test device and the target display screen is achieved through a robotic arm, and the external image acquisition device is moved to the acquisition position corresponding to the target display screen.

[0047] In one possible implementation, in response to a color accuracy test instruction for a target display screen, a testing device obtains display screen information from the target display screen. The testing device obtains environmental information about the target display screen's environment via an environmental sensor. The testing device also obtains the operating parameters and the display content of the target display screen from an external image acquisition device.

[0048] The test device is electrically connected to an external image acquisition device, and the test device can directly obtain the operating parameters from the external image acquisition device. The external image acquisition device can also transmit the acquired display content to the test device. The display content acquired by the external image acquisition device includes images and videos, and therefore can also be referred to as visual acquisition information. When testing a target display screen, the target display screen will be connected to the test device, and the test device can directly obtain the display screen information from the target display screen and send the content to be displayed to the target display screen, which will then be displayed.

[0049] Under this implementation, the test equipment obtains display information through the target display, obtains environmental information through environmental sensors, and obtains working parameters and the display content of the target display through external image acquisition equipment, thereby obtaining the data required for color accuracy testing with high data acquisition efficiency.

[0050] 302. The testing device determines a first color accuracy impact parameter of the target display screen based on the display screen information and the environmental information, where the first color accuracy impact parameter is used to indicate a degree of impact of the display screen information and the environmental information on color accuracy.

[0051] The first color accuracy influencing parameter can reflect the combined influence of the target display screen itself and the surrounding environment on the color accuracy.

[0052] In one possible implementation, the display screen information includes screen display information and screen attributes, and the environmental information includes ambient light information. The testing device determines a first reference color accuracy impact parameter of the target display screen based on the screen display information and the ambient light information, where the first reference color accuracy impact parameter is used to indicate the degree of influence of the screen display information and the ambient light information on color accuracy. The testing device determines a second reference color accuracy impact parameter of the target display screen based on the screen attributes and the ambient light information, where the second reference color accuracy impact parameter is used to indicate the degree of influence of the screen attributes and the ambient light information on color accuracy. The testing device determines the first color accuracy impact parameter of the target display screen based on the first reference color accuracy impact parameter and the second reference color accuracy impact parameter.

[0053] Among them, the screen display information includes relevant information when the target display screen displays the display content. Screen attributes are used to reflect the characteristics of the target display screen, and screen attributes usually do not change under external influences. Ambient light information is used to reflect the lighting conditions of the environment in which the target display screen is located. When conducting a color accuracy test, the target screen itself and the ambient light will affect the final test results. The first reference color accuracy impact parameter can reflect the degree of influence of the current ambient light and the display conditions of the target display screen on color accuracy. The second reference color accuracy influence degree and the first reference color accuracy influence degree reflect the degree of influence of the combination of display screen information and environmental information on color accuracy from different dimensions. Unlike the first reference color accuracy influence degree, the second reference color accuracy influence degree reflects the influence degree from the dimensions of ambient light and screen attributes.

[0054] In this embodiment, screen display information and ambient light information are used to determine a first reference color accuracy influencing parameter of the target display screen, and screen attributes and ambient light information are used to determine a second reference color accuracy influencing parameter of the target display screen, thereby determining influencing parameters of different dimensions. By combining the first reference color accuracy influencing parameter and the second reference color accuracy influencing parameter, a more accurate first color accuracy influencing parameter can be determined.

[0055] In order to explain the above embodiment more clearly, the above embodiment will be described in several parts below.

[0056] In the first part, the testing device determines a first reference color accuracy influencing parameter of the target display screen based on the screen display information and the ambient light information.

[0057] In one possible implementation, the screen display information includes screen display brightness and screen display mode, and the ambient light information includes ambient light intensity and ambient light color. The testing device determines a brightness intensity influence parameter of the target display screen based on the screen display brightness and the ambient light intensity, where the brightness intensity influence parameter is used to indicate the degree of influence of the screen display brightness and the ambient light intensity on color accuracy. The testing device determines a mode color influence parameter of the target display screen based on the screen display mode and the ambient light color, where the mode color influence parameter is used to indicate the degree of influence of the screen display mode and the ambient light color on color accuracy. The testing device determines the first reference color accuracy influence parameter based on the brightness intensity influence parameter and the mode color influence parameter.

[0058] Among them, the screen display modes include standard mode, vivid mode and eye protection mode. The display effects of the target display screen are different under different screen display modes, so different screen display modes also have an impact on the final color accuracy test results.

[0059] Under this implementation, the screen display brightness and ambient light intensity are used to determine the brightness intensity influencing parameters, and the screen display mode and ambient light color are used to determine the mode color influencing parameters, thereby realizing the determination of the influencing parameters in different dimensions. The obtained first reference color accuracy influencing parameters have high accuracy and strong interpretability.

[0060] In order to explain the above embodiment more clearly, the above embodiment will be described in several parts below.

[0061] A. The test device determines the brightness intensity influencing parameters of the target display screen based on the screen display brightness and the ambient light intensity.

[0062] In a possible implementation, the testing device substitutes the screen display brightness and the ambient light intensity into the first relationship data to obtain the brightness intensity influencing parameter.

[0063] Among them, the first relationship data is a relationship function used to express the correspondence between the screen display brightness and the ambient light intensity and brightness intensity influencing parameters. The first relationship data is calibrated or fitted by technicians according to actual conditions, and the embodiment of the present application does not limit this.

[0064] In this implementation manner, the corresponding brightness intensity influencing parameters can be obtained by substituting the screen display brightness and the ambient light intensity into the first relationship data, and the acquisition efficiency of the brightness intensity influencing parameters is relatively high.

[0065] In one possible implementation, the testing device inputs the screen display brightness and the ambient light intensity into a brightness intensity influence parameter determination model. The brightness intensity influence parameter determination model then extracts features of the screen display brightness and the ambient light intensity to obtain a brightness intensity influence feature of the target display. The testing device maps the brightness intensity influence feature using the brightness intensity influence parameter determination model to obtain the brightness intensity influence parameter.

[0066] Among them, the brightness intensity influence parameter determination model is a regression model, which can map the input screen display brightness and ambient light intensity into brightness intensity influence parameters. In the process of training the brightness intensity influence parameter determination model, the brightness intensity influence parameter determination model is actually allowed to learn the correspondence between the screen display brightness and ambient light intensity and the brightness intensity influence parameters. The embodiment of the present application does not limit the structure and training method of the brightness intensity influence parameter determination model.

[0067] For example, the test device inputs the screen display brightness and the ambient light intensity into a brightness intensity influence parameter determination model. The brightness intensity influence parameter determination model performs multiple full connections on the screen display brightness and the ambient light intensity to obtain the brightness intensity influence characteristic of the target display. The test device uses the brightness intensity influence parameter determination model to fully connect and normalize the brightness intensity influence characteristic to obtain the brightness intensity influence parameter.

[0068] B. The test device determines the mode color impact parameters of the target display screen based on the screen display mode and the ambient light color.

[0069] In a possible implementation, the testing device substitutes the mode parameters of the screen display mode and the ambient light color into the second relationship data to obtain the mode color impact parameter.

[0070] The second relationship data is a relationship function that represents the relationship between the mode parameters of the screen display mode and the ambient light color and mode color influencing parameters. The second relationship data is obtained by calibration or fitting by a technician based on actual conditions and is not limited in this embodiment of the present application. The mode parameter is used to represent the impact of the corresponding screen display mode on the display process of the target display screen. For example, the mode parameter is at least one of a brightness adjustment parameter, a contrast adjustment parameter, a color temperature adjustment parameter, and a color saturation adjustment parameter.

[0071] In this implementation, the corresponding mode color influence parameters can be obtained by substituting the mode parameters of the screen display mode and the ambient light color into the second relationship data, and the acquisition efficiency of the mode color influence parameters is relatively high.

[0072] In one possible implementation, the testing device inputs the mode parameters of the screen display mode and the ambient light color into a mode color impact parameter determination model. The mode color impact parameter determination model then extracts features of the mode parameters of the screen display mode and the ambient light color to obtain mode color impact features of the target display screen. The testing device maps the mode color impact features using the mode color impact parameter determination model to obtain the mode color impact parameters.

[0073] Among them, the mode color influence parameter determination model is a regression model, which can map the mode parameters of the input screen display mode and the ambient light color into mode color influence parameters. In the process of training the mode color influence parameter determination model, the mode color influence parameter determination model is actually allowed to learn the correspondence between the mode parameters of the screen display mode and the ambient light color and the mode color influence parameters. The embodiment of the present application does not limit the structure and training method of the mode color influence parameter determination model.

[0074] For example, the test device inputs the pattern parameters and the ambient light color into a pattern color impact parameter determination model. The pattern color impact parameter determination model performs multiple full connections on the pattern parameters and the ambient light color to obtain the pattern color impact characteristics of the target display. The test device uses the pattern color impact parameter determination model to fully connect and normalize the pattern color impact characteristics to obtain the pattern color impact parameters.

[0075] C. The testing device determines the first reference color accuracy influencing parameter based on the brightness intensity influencing parameter and the mode color influencing parameter.

[0076] In a possible implementation, the testing device performs weighted fusion on the brightness intensity influencing parameter and the pattern color influencing parameter to obtain the first reference color accuracy influencing parameter.

[0077] Among them, the weight of the weighted fusion is used to reflect the confidence of the corresponding influencing parameter. The weight of the weighted fusion is set by the technician according to the actual situation, or determined by the test equipment according to the brightness intensity influencing parameter and the mode color influencing parameter. The embodiment of the present application does not limit this.

[0078] In the second part, the testing device determines a second reference color accuracy influencing parameter of the target display screen based on the screen attributes and the ambient light information.

[0079] In one possible implementation, the screen attributes include screen material and pixel array type, and the ambient light information includes ambient light intensity and ambient light color.

The testing device determines the second reference color accuracy impact parameter based on the color material impact information and the array ambient light impact information.

[0080] Among them, screen materials include LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode). LCD and OLED have many subcategories.

[0106] Among them, the temperature influence parameter determination model is a regression model, which can map the input display screen temperature and ambient temperature into temperature influence parameters. In the process of training the temperature influence parameter determination model, the temperature influence parameter determination model is actually allowed to learn the correspondence between the display screen temperature, ambient temperature and temperature influence parameters. The embodiment of the present application does not limit the structure and training method of the temperature influence parameter determination model.

[0107] For example, the test device inputs the display screen temperature and the ambient temperature into a temperature impact parameter determination model. The temperature impact parameter determination model then performs multiple full connections on the display screen temperature and the ambient temperature to obtain the temperature impact characteristic of the target display screen. The test device then performs full connections and normalization on the temperature impact characteristic using the temperature impact parameter determination model to obtain the temperature impact parameter.

[0108] In the second part, the test equipment determines the temperature and humidity impact parameters based on the display screen temperature and the ambient humidity.

[0109] In a possible implementation, the testing device substitutes the display screen temperature and the ambient humidity into fourth relationship data to obtain the temperature and humidity influencing parameter.

[0110] Among them, the fourth relationship data is a relationship function used to express the correspondence between the display screen temperature, ambient humidity and temperature and humidity influencing parameters. The fourth relationship data is calibrated or fitted by technicians according to actual conditions, and the embodiment of the present application does not limit this.

In the process of training the temperature and humidity influence parameter determination model, the temperature and humidity influence parameter determination model is actually allowed to learn the correspondence between the display screen temperature and ambient humidity and the temperature and humidity influence parameters. The embodiment of the present application does not limit the structure and training method of the temperature and humidity influence parameter determination model.

[0114] For example, the test device inputs the display screen temperature and the ambient humidity into a temperature and humidity influence parameter determination model.

The operational stability information indicates the operational stability of the external image acquisition device and is determined based on the device's operational log.

[0118] In this embodiment, the temperature impact parameter and the temperature and humidity impact parameter are fused to obtain a first fused parameter. This first fused parameter can comprehensively reflect the degree of influence of temperature and humidity on color accuracy. A device acquisition impact parameter is determined based on the operational stability information and the display content acquisition parameter, thereby determining the degree of influence of the external acquisition device on color accuracy. A second color accuracy impact parameter is determined using the first fused parameter and the device acquisition impact parameter. The second color accuracy impact parameter has a higher accuracy.

[0119] In order to explain the above embodiment more clearly, the above embodiment will be described in several parts below.

[0125] C. The testing device determines the second color accuracy influencing parameter based on the first fusion parameter and the device acquisition influencing parameter.

[0126] In a possible implementation, the testing device performs weighted fusion on the first fusion parameter and the device acquisition influencing parameter to obtain the second color accuracy influencing parameter.

[0127] Among them, the weights of weighted fusion are set by technical personnel according to actual conditions, and the embodiments of this application do not limit this.

[0128] 304. The testing device determines a test score of the target display screen based on the first color accuracy influencing parameter, the second color accuracy influencing parameter, the display content, and standard color information of the display content, where the test score is used to represent color accuracy.

[0129] The test score is positively correlated with color accuracy, that is, the higher the test score, the higher the color accuracy, and the lower the test score, the lower the color accuracy.

[0130] In one possible implementation, a testing device determines the content type of the displayed content and obtains captured color information of the displayed content, where the content type includes images and videos. The testing device determines a color accuracy correction parameter based on the content type, the first color accuracy influencing parameter, and the second color accuracy influencing parameter. The testing device then determines a test score for the target display based on the captured color information, the color accuracy correction parameter, and the standard color information.

[0131] The acquired color information is the color information of the display content acquired by an external image acquisition device, and the standard color information is the true color information of the display content, which is stored in the storage medium of the test device. In some embodiments, the color information includes pixel values of multiple pixels in the display content.

[0132] In order to explain the above embodiment more clearly, the above embodiment will be described in several parts below.

[0133] In the first part, the testing device determines the content type of the display content and obtains the acquired color information of the display content.

[0136] In one possible implementation, the testing device determines a type correction parameter for the displayed content based on the content type, and combines the type correction parameter, the first color accuracy influencing parameter, and the second color accuracy influencing parameter to obtain the color accuracy correction parameter.

[0137] For example, the test device uses the content type to query and obtains a type correction parameter for the displayed content. The test device weightedly combines the type correction parameter, the first color accuracy impact parameter, and the second color accuracy impact parameter to obtain the color accuracy correction parameter.

[0138] Among them, the weights of weighted fusion are set by technical personnel according to actual conditions, and the embodiments of this application do not limit this.

[0139] Part three: The testing device determines a test score of the target display screen based on the collected color information, the color accuracy correction parameter, and the standard color information.

[0140] The test score ranges from (0, 1).

[0141] In one possible implementation, the test device uses the color accuracy correction parameter to correct the collected color information to obtain corrected color information of the target display screen. The test device determines a test score for the target display screen based on the difference between the corrected color information and the standard color information.

[0142] For example, the color accuracy correction parameters include a correction matrix and a correction bias matrix. The collected color information is the collected pixel value matrix of the display content. The test device performs a dot multiplication of the collected color information with the collected pixel value matrix and then adds the result to the correction bias matrix to obtain the corrected color information, which is the corrected pixel value matrix. The test device maps the difference information between the corrected color information and the standard color information to determine the test score of the target display. That is, the corrected pixel value matrix is subtracted from the standard pixel value matrix corresponding to the standard color information to obtain a pixel difference matrix. The test device fully connects and normalizes the pixel difference matrix to obtain the test score of the target display.

[0143] Optionally, after step 304 , the following step 305 or 306 can also be executed.

[0144] 305. When the test score is greater than or equal to the preset test score, the testing device determines that the target display screen passes the color accuracy test.

[0145] The preset test score is associated with the screen type of the target display screen and the test requirements. The following describes how to determine the preset test score.

[0146] In some embodiments, the testing device extracts features of the target display screen type and the test requirements to obtain screen type features of the target display screen and test requirement features of the test requirements. The testing device fuses the screen type features and the test requirement features to obtain score determination features. The testing device fully connects and normalizes the score determination features to obtain the preset test score.

[0147] 306. When the test score is less than the preset test score, the testing device determines that the target display screen fails the color accuracy test.

[0148] All of the above optional technical solutions can be combined in any way to form optional embodiments of the present application, and will not be described in detail here.
