Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of LED display screen testing, and in particular to a temperature testing method, device and computer equipment for an LED display screen. Background Art

[0002] Nowadays, a large number of LED components are generally arranged in a specific array on LED (Light Emitting Diode) display screens. Each LED component is equipped with a red light-emitting unit R (Red-LED), a green light-emitting unit G (Green-LED) and a blue light-emitting unit B (Blue-LED). The color of each LED component can be changed by adjusting the RGB value (including the brightness values ​​of R, G and B) in each LED component. Generally, when testers perform temperature tests on LED display screens according to traditional schemes, they will make the LED display screen display random content, or display a pure white color image (the corresponding RGB value is (255, 255, 255)), or change the power value of the LED display screen by only changing the brightness and color temperature of the LED display screen.

[0003] Traditional methods of testing the temperature of LED display screens mainly include testing with random content, testing by controlling the brightness and color temperature of the full-screen LED, and testing with pure color content. However, traditional methods are often one-sided and have a large degree of randomness. For example, when using random content for testing, it may happen that a certain content can pass the test, but other content may not pass the test; when testing by controlling the brightness and color temperature of the LED, the color of the full-screen LED display cannot be changed, and the test of the LED display when displaying various colors is ignored; when using pure color content for testing, there is a difference between the content actually played by the LED display, and the LED display may fail the test when playing pure white content, but in fact the LED display will not play pure white content for a long time.

[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] The temperature testing method of the LED display provided in this application can be applied to Figure 1In the application environment shown, the LED display screen 102 communicates with the computer device 104 via wired or wireless means. The computer device 104 may be, but is not limited to, various personal computers, laptops, smart phones, and tablet computers, and the computer device 104 may include a display screen.

[0053] In certain exemplary embodiments of the present disclosure, Figure 2 As shown, a temperature test method for an LED display screen is provided. Figure 1 Taking a computer device as an example, the method includes the following steps:

[0054] Step S202: displaying each chessboard image in sequence on the LED display screen, each chessboard image including a white image area and another non-white pure color image area that appear alternately in the horizontal direction and the vertical direction.

[0055] The number of chessboard images can be determined according to actual needs, and the colors of the pure color image areas of each chessboard image are different colors. Figure 3 As shown, the checkerboard image includes white image areas that alternately appear horizontally and vertically ( Figure 3 The area marked with "white" in the image) and another non-white solid color image area ( Figure 3 The area marked with the word "pure" in the image is shown in the figure), wherein the color of the pure color image area can be selected from other colors except white as needed, for example, it can be but not limited to black, blue, green, red, cyan, magenta and yellow, and the color of the white image area is white. Among them, in the same chessboard image, the sum of the areas of the white image area and the sum of the areas of the pure color image area can be equal or unequal. In the same chessboard image, the number of white image areas and the number of pure color image areas can be the same or the same. In the same chessboard image, the areas of different white image areas can be the same or different. Similarly, the areas of different pure color image areas can be equal or unequal. For any pair of two different chessboard images, the sum of the areas of the white image areas of the two images can be equal or unequal. The sum of the areas of the pure color image areas of the two images can be equal or unequal. The sum of the number of white image areas of the two images can be consistent or inconsistent. In addition, the sum of the number of pure color image areas of the two images can be consistent or inconsistent.

[0056] Among them, after the style of the chessboard image is selected, for example Figure 3As shown, the computer device selects a chessboard image with equal areas of white image area and pure color image area, and the user can set the RGB value of the pure color image area to make the computer device generate a corresponding chessboard image. Specifically, the computer device receives the RGB setting value of the pure color image area, generates a corresponding chessboard image according to the RGB setting value of the pure color image area, and transmits the generated chessboard image to the LED display screen for display. Alternatively, the computer device can directly transmit the RGB setting value of the pure color image area to the LED display screen for display.

[0057] Exemplarily, the RGB setting values ​​received by the computer device are (0, 0, 0), (0, 0, 255), (0, 255, 0), (255, 0, 0), (0, 255, 255), (255, 0, 255), and (255, 255, 0), and the checkerboard images displayed on the LED display screen are black and white checkerboard images, blue and white checkerboard images, green and white checkerboard images, red and white checkerboard images, cyan and white checkerboard images, magenta and white checkerboard images, and yellow and white checkerboard images. Figure 4 The figure shows a schematic diagram of a plurality of color chessboard images, wherein from left to right are a yellow and white chessboard image, a magenta and white chessboard image, a cyan and white chessboard image, a blue and white chessboard image, a black and white chessboard image, a red and white chessboard image, and a green and white chessboard image. Figure 5 As shown, if the RGB setting value received by the computer device is (0, 0, 0), a black and white chessboard image is displayed on the LED display. If the RGB setting value is (255, 0, 0), a red and white chessboard image is displayed. If the RGB setting value is (0, 255, 0), a green and white chessboard image is displayed.

[0058] Step S204: acquiring first temperature values ​​of the LED display screen, wherein the first temperature values ​​are temperature detection values ​​of the LED display screen after the LED display screen displays each chessboard image and the screen temperature of the LED display screen reaches a stable state.

[0059] Specifically, the computer device can display a chessboard image on the LED display screen each time, wait until the screen temperature of the LED display screen reaches a stable state and then obtain the temperature value of the LED display screen, and use the obtained temperature value as the first temperature value corresponding to the chessboard image, and use this method to obtain the first temperature values ​​of the LED display screen in sequence. Among them, there can be multiple ways to determine whether the screen temperature of the LED display screen has reached a stable state. For example, method one: when the computer device detects that the screen temperature of the LED display screen no longer increases within a set time, it is determined that the screen temperature has reached a stable state. Method two: when the computer device analyzes that the rate of change of the screen temperature of the LED display screen over time is equal to 0, it is determined that the screen temperature has reached a stable state. Method three: when the computer device detects that the heating power of the LED display screen is equal to or matches the screen heat dissipation efficiency at the current ambient temperature, it is determined that the screen temperature has reached a stable state.

[0060] Step S206: determining the temperature test result of the LED display screen according to each first temperature value and the color of the corresponding pure color image area of ​​each chessboard image.

[0061] Specifically, the computer device can compare each first temperature value with a preset temperature threshold value to determine whether the corresponding chessboard image can pass the test, and then obtain the temperature test result of the LED display screen, and the temperature test result can include the color information of the chessboard image that passed the test or / and the color information of the chessboard image that did not pass the test, where the color information refers to the color of the pure color image area of ​​the corresponding chessboard image. The temperature threshold value can be determined according to the actual safe operating temperature of the LED display screen.

[0062] Exemplarily, assuming that the temperature threshold is 60 degrees Celsius, the computer device finds after detection that: when the LED display screen displays various checkerboard images, the colors of the pure color image area are black, blue and green checkerboard images, and the corresponding first temperature values ​​are all less than 60 degrees Celsius, and the colors of the pure color image area are other colors of checkerboard images, and the corresponding first temperature values ​​are all greater than 60 degrees Celsius. Then the temperature test result of the LED display screen may include checkerboard images that pass the test with colors of black, blue and green, or it may be a checkerboard image including a pure color image area with colors of black, blue and green.

[0063] In the above-mentioned temperature testing method of the LED display screen, since the computer device designs a series of chessboard images for the LED display screen to display, a comprehensive and quantitative temperature test of the LED display screen is achieved, thereby improving the accuracy and reliability of the temperature test results of the LED display screen.

[0064] In some other exemplary embodiments of the present disclosure, a pure color image may be used for testing first, and if the test fails when the pure color image is used, a checkerboard image may be used for testing. Specifically, Figure 6 As shown, the method may also include the following steps:

[0065] Step S602: displaying each pure color image in sequence on the LED display screen.

[0066] Here, a pure color image refers to an image that includes only one color, such as Figure 7 As shown, the colors of each solid color image include but are not limited to black, blue, green, cyan, red, magenta, yellow and white.

[0067] Specifically, the computer device can receive the RGB setting values ​​of each pure color image, generate each pure color image respectively, and then transmit the generated pure color image to the LED display screen for display. Among them, each pure color image is displayed in full screen on the LED display screen. After the color of the pure color image is selected by the user, the computer device receives the RGB setting value of the pure color image, generates a corresponding pure color image according to the RGB setting value of the pure color image, and transmits the generated pure color image to the LED display screen for display. Alternatively, the computer device can directly transmit the RGB setting value of the pure color image to the LED display screen for display. In addition, after the computer device completes the temperature detection work on the LED display screen displaying the current pure color image, it needs to display the next pure color image on the LED display screen in the order required by the test task, and prepare for the next step of temperature detection work. By analogy, each pure color image can be displayed in sequence on the LED display screen in this order.

[0068] For example, Figure 8 As shown, when the RGB setting value of the pure color image received by the computer device is (0, 0, 0), the color of the pure color image displayed on the LED display screen is black. If the RGB setting value is (255, 0, 0), the color of the pure color image displayed is red. Alternatively, if the RGB setting value is (255, 255, 255), the color of the pure color image displayed is white.

[0069] Step S604: acquiring second temperature values ​​of the LED display screen, which are temperature detection values ​​of the LED display screen after the LED display screen displays each pure color image and the screen temperature reaches a stable state.

[0070] Specifically, the computer device may wait until the screen temperature of the LED display screen reaches a stable state each time after displaying a pure color image in full screen on the LED display screen, and then obtain the temperature value of the LED display screen as the second temperature value corresponding to the pure color image, and sequentially obtain the second temperature values ​​of the LED display screen in this manner. There are multiple ways to determine whether the screen temperature of the LED display screen reaches a stable state, and the specific ways are as described in the above embodiments, which will not be described in detail here.

[0071] Step S606: In response to any second temperature value being greater than a preset temperature threshold, the process proceeds to a step of sequentially displaying each chessboard image on the LED display screen.

[0072] Specifically, the computer device can compare each second temperature value with a preset temperature threshold value. When any second temperature value is greater than the preset temperature threshold value, the step of sequentially displaying each chessboard image on the LED display screen is entered, that is, the process of testing according to the chessboard image is started. The temperature threshold value of this step is also determined according to the actual safe operating temperature of the LED display screen. The computer device can also determine each second temperature value that needs to be entered into the temperature test result according to the preset temperature threshold value.

[0073] For example, assuming that the temperature threshold is 60 degrees Celsius, the computer device finds after temperature testing that when the LED display screen displays a solid color image in black, blue, and green, the corresponding second temperature values ​​are all less than 60 degrees Celsius. However, when the LED display screen displays a solid color image in white, the corresponding second temperature value exceeds 60 degrees Celsius, or when the LED display screen displays a solid color image in white, yellow, and red, the corresponding second temperature values ​​exceed 60 degrees Celsius, then the computer device needs to enter the above-mentioned step of sequentially displaying each chessboard image on the LED display screen. Generally, when the LED display screen displays a solid color image in white, the heating efficiency of the screen is relatively high, while the heating efficiency of the screen when displaying other colors is relatively low.

[0074] Furthermore, after the above temperature test, the computer device can also obtain a quantitative temperature test result, specifically: when the RGB setting value of the pure color image received by the computer device is (0, 0, 0), (0, 0, 255) or (0, 255, 0), the corresponding second temperature value will be less than 60 degrees Celsius. However, when the RGB setting value is (255, 255, 255), the corresponding second temperature value will definitely exceed 60 degrees Celsius.

[0075] In the temperature testing method for the above-mentioned LED display screen, since the computer equipment performs a preliminary temperature test on the LED display screen displaying pure color content, a series of chessboard images are designed for the LED display screen that will overheat when displaying pure color content to perform display, which not only avoids invalid chessboard image display and temperature detection of the LED display screen, but also realizes quantitative temperature testing of the LED display screen.

[0076] In some embodiments, each pure color image is displayed in sequence on the LED display screen, such as Fig. 9 As shown, the method includes:

[0077] Step S902: Displaying a pure white image on the LED display screen.

[0078] Specifically, the computer device can set the RGB value of the full-screen LED display screen to (255, 255, 255), so that the LED display screen displays a pure white image.

[0079] Step S904: other pure color images are displayed in sequence on the LED display screen by respectively reducing the color values ​​of the three color channels according to the set first brightness gradient.

[0080] Specifically, the first brightness gradient does not exceed half of the highest color value of a single color channel, so that the R channel, the G channel, and the B channel can have at least three different display states, ensuring that the gradient distinction of the color value is detailed. For example, if the first brightness gradient is set to 128, three different display states of 0, 128, and 255 can appear on the R channel. If the first brightness gradient is set to 64, five different display states of 0, 64, 128, 192, and 255 can appear on the R channel.

[0081] For example, assuming that the first brightness gradient is set to 128, the computer device can first reduce the R channel of the full screen from 255 to 128, and the RGB value of the LED display screen is (128, 255, 255). Then, in the next adjustment, the R channel of the full screen can be reduced from 128 to 0, and the RGB value of the LED display screen is (0, 255, 255); or, in the second adjustment, the G channel of the full screen can be reduced from 255 to 128, and the RGB value of the LED display screen is (128, 128, 255).

[0082] By analogy, assuming that the RGB value of the LED display screen (128, 255, 255) is used as the starting point for adjustment, after the computer device has adjusted the LED display screen once, the RGB value of the LED display screen can be: (255, 255, 128), (255, 128, 255) or (128, 255, 255). After two adjustments, its RGB value can be: (255, 128, 128), (128, 255, 128), (128, 128, 255), (0, 255, 128), (255, 0, 255), (0, 255, 255) or (255, 255, 0). After 3 adjustments, its RGB values ​​can be: (255, 128, 0), (128, 0, 255), (0, 255, 128), (128, 128, 128), (0, 128, 255), (128, 255, 0), (0, 255, 128). After 4 adjustments, its RGB values ​​can be: (0, 255, 0), (255, 0, 0), (0, 0, 255), (128, 128, 0), (128, 0, 128), (0, 128, 128). After 5 adjustments, its RGB values ​​can be: (0, 128, 0), (0, 0, 128), (128, 0, 0). After the computer device is adjusted for the 6th time, its RGB value drops to the lowest (0, 0, 0).

[0083] In the temperature testing method of the above-mentioned LED display screen, since the computer device reduces the color values ​​of the R channel, the G channel and the B channel respectively according to the set first brightness gradient, each pure color image displayed in the LED display screen can be obtained, which is used to perform a preliminary temperature test on the LED display screen quantitatively.

[0084] In some embodiments, displaying each chessboard image in sequence on the LED display screen includes:

[0085] The area ratio of the white image area to the pure color area is determined according to the preset test requirements, and each chessboard image determined according to the area ratio is displayed on the LED display screen. The color of the pure color image area of ​​these chessboard images is obtained according to the set second brightness gradient change.

[0086] Specifically, the second brightness gradient may be equal to or different from the first brightness gradient, and the second brightness gradient does not exceed half of the highest color value of a single color channel. Assuming that the second brightness gradient is set to 128, the computer device can adjust the LED display screen according to the above adjustment method of "when the first brightness gradient is set to 128", thereby obtaining each chessboard image. However, the difference is that when the computer device is ready to adjust the color of the pure color image area of ​​the chessboard image, the color of its pure color image area is not white.

[0087] For example, when the area ratio of the white image area to the pure color area is equal to 1:1, the checkerboard image is as follows: Figure 3 When the area ratio of the white image area to the pure color area is not equal to 1:1, the chessboard image is as follows Fig.10 As shown in the figure, there are two pure color areas, one large and one small. Generally, since the local heating efficiency of the white image area is relatively higher, the LED display screen will Fig.10 When displaying a checkerboard pattern as shown, the heat generation power of the entire screen will be less than when displaying Figure 3 The chessboard image shown is the heating power of the entire screen. If the test requirement is: the heating power of the entire LED display screen is required to be smaller and the steady-state temperature is lower, the computer equipment can choose Fig.10 The checkerboard image shown is used to display the image.

[0088] In addition, assuming that before the computer device adjusts the color of the pure color image area of ​​the chessboard image, the color of the pure color image area is light yellow (RGB value is "255, 255, 128"), then after one adjustment, the RGB value of the LED display screen can be: (255, 128, 128), (128, 255, 128), (255, 255, 0). Similarly, the computer device makes adjustments in this way for multiple times and obtains the RGB value of each pure color image, and then obtains each chessboard image.

[0089] In the temperature testing method of the above-mentioned LED display screen, since the computer device reduces the color values ​​of the R channel, the G channel and the B channel respectively according to the set first brightness gradient, each chessboard image displayed in the LED display screen can be obtained for quantitatively performing temperature testing on the LED display screen.

[0090] In some embodiments, displaying each chessboard image in sequence on the LED display screen further includes:

[0091] When the pure color image area of ​​the chessboard image displayed on the LED display screen is any color, the brightness of the white image area of ​​the chessboard image is changed according to the set third brightness gradient, and different chessboard images are obtained for display.

[0092] Specifically, the third brightness gradient may be equal to or different from the first brightness gradient or the second brightness gradient, and the third brightness gradient does not exceed half of the highest color value of any color channel, and the brightness ratio between RGB in the white image area needs to be maintained at 1:1:1. Each time the computer device changes the brightness of the white image area, it needs to simultaneously and equally lower the brightness of RGB.

[0093] For example, assuming that the third brightness gradient is set to 128, the color of the white image area of ​​the chessboard image displayed on the LED display is originally white (RGB value is "255, 255, 255"). At this time, the computer device needs to simultaneously lower the RGB brightness value according to the gradient of 128, and adjust the color / brightness of the white image area of ​​the chessboard image to gray (RGB value is "128, 128, 128") and black (RGB value is "0, 0, 0") in turn.

[0094] In the temperature testing method of the LED display screen, since the computer device lowers the brightness of RGB in an equal gradient, each checkerboard image after adjusting the brightness of the white image area can be obtained and displayed on the LED display screen, which is used for further temperature testing of the LED display screen.

[0095] In some embodiments, the temperature test result of the LED display screen is determined according to each first temperature value and the color of each corresponding chessboard image, such as Fig.11 As shown, including:

[0096] Step S1102: Filter out at least one chessboard image whose corresponding first temperature value does not exceed the temperature threshold, and obtain the power consumption value of the LED display screen when displaying the at least one chessboard image.

[0097] Specifically, the temperature threshold of this step is also set according to the actual safe operating temperature of the LED display. When the LED display displays any chessboard image and the temperature rises to a stable state, the computer device measures the first temperature value of the LED display when the chessboard image is displayed, and then the computer device can select at least one chessboard image whose corresponding first temperature value does not exceed the temperature threshold from each detected first temperature value according to the temperature threshold.

[0098] Step S1104: Generate a temperature test result of the LED display screen according to the color of the pure color image area corresponding to at least one chessboard image, the area ratio of the white image area to the pure color area, and the power consumption value.

[0099] Exemplarily, assuming that the temperature threshold is set to 60 degrees Celsius, the computer device screens all the measured first temperature values ​​according to the temperature threshold and finds that when the LED display screen displays olive green (RGB value is "128, 128, 0"), purple (RGB value is "128, 0, 128") and cyan (RGB value is "0, 128, 128") checkerboard images, the corresponding first temperature value does not exceed 60 degrees Celsius. When the LED display screen displays other colors, such as a red (RGB value is "255, 0, 0") checkerboard image, the corresponding first temperature value exceeds 60 degrees Celsius. The computer device will then measure the corresponding power consumption values ​​of the LED display screen when it displays the olive green, purple and cyan checkerboard images, and record the temperature test results. The final temperature test results may include: the area ratio of olive green, purple, cyan, and white image areas to pure color areas is 1:1; when the LED display screen displays olive green, purple, and cyan checkerboard images, the corresponding power consumption values ​​are 55 watts, 58 watts, and 60 watts, respectively.

[0100] In the temperature testing method of the LED display screen, since the computer device determines the temperature test result by screening, a comprehensive and quantitative temperature test of the LED display screen is achieved, thereby improving the accuracy and reliability of the temperature test result of the LED display screen.

[0101] In some embodiments, the temperature test result of the LED display screen is determined according to each first temperature value and the color of each corresponding chessboard image, such as Fig.12 As shown, including:

[0102] Step S1202: screening out at least one chessboard image whose corresponding first temperature value does not exceed the temperature threshold, and screening out at least one pure color image whose second temperature value does not exceed the temperature threshold.

[0103] Specifically, the temperature threshold of this step is also set according to the actual safe operating temperature of the LED display. When the LED display is displaying any pure color image and the temperature rises to a stable state, the computer device measures the second temperature value of the LED display when displaying the pure color image. Then, according to the temperature threshold, the computer device can filter out at least one chessboard image whose corresponding first temperature value does not exceed the temperature threshold from each detected first temperature value. And according to the same temperature threshold, filter out at least one pure color image whose corresponding second temperature value does not exceed the temperature threshold from each detected second temperature value.

[0104] Step S1204: Generate a temperature test result of the LED display screen according to the color of the pure color area corresponding to at least one chessboard image and the color of at least one pure color image.

[0105] Exemplarily, assuming that the temperature threshold is set to 60 degrees Celsius, the computer device screens the various first temperature values ​​measured according to the temperature threshold and finds that when the LED display screen displays a checkerboard image of olive green (RGB value "128, 128, 0"), purple (RGB value "128, 0, 128"), and cyan (RGB value "0, 128, 128"), the corresponding first temperature value does not exceed 60 degrees Celsius. It is also found that when the LED display screen displays a pure color image of lime green (RGB value "0, 255, 0"), red (RGB value "255, 0, 0"), blue (RGB value "0, 0, 255"), olive green (RGB value "128, 128, 0"), purple (RGB value "128, 0, 128"), and cyan (RGB value "0, 128, 128"), the corresponding second temperature value does not exceed 60 degrees Celsius. It can be determined that the temperature test results should include: olive green, purple and cyan for the checkerboard image, and orange-green, red, blue, olive green, purple and cyan for the solid color image.

[0106] In the temperature testing method for the above-mentioned LED display, since the computer equipment preliminarily obtains the colors of each pure color image and each chessboard image that meet the safe operation requirements of the LED display through screening, it is convenient to conduct a deeper functional temperature test on the LED display, thereby improving the availability and accuracy of the temperature test results.

[0107] In some embodiments, the temperature test results of the LED display are generated, such as Fig.13 As shown, the method also includes:

[0108] Step S1302: obtaining a first type of power consumption value when the LED display screen displays at least one chessboard image, and a second type of power consumption value when the LED display screen displays at least one pure color image.

[0109] Specifically, the first type of power consumption value is the power consumption value when the LED display screen displays a specific chessboard image while ensuring that the first temperature value does not exceed the temperature threshold. The second type of power consumption value is the power consumption value when the LED display screen displays a specific pure color image while ensuring that the second temperature value does not exceed the temperature threshold. The way in which the computer device obtains the power consumption value can be obtained by referring to the power consumption value comparison table of the LED display screen, or it can be obtained after actual measurement.

[0110] Step S1304: entering the first type of power consumption value corresponding to at least one chessboard image and the second type of power consumption value corresponding to at least one solid color image into the temperature test result.

[0111] Specifically, the computer device can use the corresponding colors of the above-mentioned pure color images and checkerboard images that meet the safe operation requirements of the LED display as target working conditions, and when the LED display is executing the above-mentioned working conditions, it measures the first type of power consumption value and the second type of power consumption value.

[0112] For example, it is assumed that the colors of each pure color image and each chessboard image that meet the safe operation requirements of the LED display screen include: olive green, purple and cyan for chessboard images, and orange green, red, blue, olive green, purple and cyan for pure color images. Then the computer device determines the first-class power consumption value corresponding to the LED display screen when displaying the olive green, purple and cyan chessboard images. And the second-class power consumption value corresponding to the LED display screen when displaying the orange green, red, blue, olive green, purple and cyan pure color images is determined, and the temperature test result is recorded. The final temperature test result may include: when the LED display screen displays the olive green, purple and cyan chessboard images, the first-class power consumption values ​​corresponding to each of them are 55 watts, 58 watts and 60 watts respectively. And when the LED display screen displays the orange green, red, blue, olive green, purple and cyan pure color images, the second-class power consumption values ​​corresponding to each of them are 50 watts, 52 watts, 52 watts, 53 watts, 54 watts and 53 watts respectively.

[0113] In the temperature testing method of the above-mentioned LED display screen, since the computer equipment determines the colors of each pure color image and each checkerboard image that meets the safe operation requirements of the LED display screen, and their corresponding power consumption values, it can be used to reflect the functional indicators of the LED display screen, thereby improving the effectiveness and accuracy of the temperature test results.

[0114] It should be noted that, with respect to the various steps included in the temperature testing method for an LED display screen provided in any of the above embodiments, unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of these steps may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
