Description

Technical Field

[0001] This application relates to the field of LED displays, and in particular to a method, apparatus and storage medium for low-temperature LED display. Background Technology

[0002] Currently, compared with other electronic displays (such as LCD screens), although LED displays are also made by splicing multiple unit boards, the LED beads of LED displays are encapsulated on the unit boards, which makes the spliced ​​display screen more complete. At the same time, due to its adjustable brightness and waterproof and moisture-proof features, LED displays have been widely used in various places.

[0003] While LED displays can be used in various locations, due to the characteristics of their components (such as light-emitting diodes and power supplies), the lowest temperature at which LED displays can typically operate normally is -20°C. Therefore, in some colder environments, LED displays will not function properly (e.g., they may fail to power on). Thus, ensuring that LED displays can operate normally in low-temperature environments has become a challenge. Summary of the Invention

[0004] In order to enable LED displays to function normally in low-temperature environments, this application provides a method for low-temperature LED display.

[0005] In a first aspect, this application provides a method for low-temperature display on an LED display screen, employing the following technical solution:

[0006] A method for low-temperature display on an LED display screen includes:

[0007] If a user-triggered temperature acquisition command is detected, the current temperature of each unit board in the LED display screen is acquired, and each unit board has a corresponding heating device.

[0008] If the current temperature of at least one unit board has not reached the first preset temperature, then the at least one unit board is identified as a unit board to be heated, and the position information of the unit board to be heated is obtained.

[0009] Based on the position information of the unit board to be heated, the heating device corresponding to the unit board to be heated is controlled to heat the unit board to be heated;

[0010] When heated to the first preset temperature, the LED display screen is controlled to display.

[0011] By adopting the above technical solution, when a user-triggered temperature acquisition command is detected, it indicates that the LED display screen needs to be turned on. However, since the LED display screen may not turn on when the temperature is too low, it is necessary to acquire the current temperature of the unit boards inside the LED display screen to determine whether the unit boards can be turned on normally. When the current temperature has not reached the first preset temperature, it indicates that the unit board needs to be heated. This unit board is identified as the unit board to be heated, and its position information is acquired to determine the specific location of the unit board to be heated. This allows for the control of the corresponding heating device to heat the unit board based on its position information, thus facilitating more accurate heating. When the temperature reaches the first preset temperature, it indicates that the LED display screen can display normally, and the LED display screen is controlled to display. This achieves the effect of normal operation of the LED display screen under low temperature conditions.

[0012] In another possible implementation, controlling the heating device corresponding to the unit board to be heated to heat the unit board includes:

[0013] Obtain the heating rate of the heating device;

[0014] Based on the first preset temperature, the heating rate, and the current temperature, the heating time of the unit board to be heated is determined;

[0015] The heating unit board is heated based on the heating time.

[0016] By adopting the above technical solution, the heating rate of the heating device is obtained, so that the heating time of the corresponding unit board to be heated can be determined according to the first preset temperature, the heating rate, and the current temperature. This allows the electronic device to accurately know the specific duration for which the heating device needs to heat the unit board. Consequently, when the electronic device heats the unit board according to the heating time, it can more accurately ensure that the unit board reaches the first preset temperature.

[0017] In another possible implementation, determining the heating time of the unit board to be heated based on the first preset temperature, the heating rate, and the current temperature includes:

[0018] The temperature difference value is obtained by subtracting the first preset temperature from the current temperature;

[0019] Based on the temperature difference and the heating rate, the heating time of the unit board to be heated is calculated.

[0020] By employing the above technical solution, the difference between the first preset temperature and the current temperature is calculated to obtain a temperature difference value. This allows for the calculation of the heating time for the unit board to be heated based on the temperature difference and the heating rate. Consequently, subsequent electronic devices can heat the unit board according to the required heating time.

[0021] In another possible implementation, heating the unit board based on the heating time includes:

[0022] Obtain the number of the unit plates to be heated;

[0023] If the number of the unit boards to be heated is one, then the unit board to be heated is heated based on the heating time.

[0024] If the number of the heating unit boards is at least two, the heating time corresponding to each heating unit board is sorted to obtain a sorting result, and each heating unit board is heated based on the sorting result.

[0025] By adopting the above technical solution, the number of unit boards to be heated is obtained, which facilitates the determination of the specific heating measures for each unit board. When there is only one unit board to be heated, it is only necessary to heat it according to the corresponding heating time. However, when there are at least two unit boards to be heated, to avoid incomplete display of the LED screen, it is necessary to ensure that the unit boards to be heated can be used normally at the same time. That is, the unit boards to be heated must reach the normal operating temperature at the same time. The heating time corresponding to each unit board to be heated is sorted, and the sorting result is obtained. Each unit board to be heated is heated according to the sorting result, so that each unit board to be heated can reach the normal operating temperature at the same time, thereby reducing the number of situations where the LED screen cannot display simultaneously.

[0026] In another possible implementation, heating each of the unit plates to be heated based on the sorting result includes:

[0027] Based on the sorting results, the maximum heating time and the heating sequence of the at least two heating unit plates are determined;

[0028] The waiting time for each heating unit is obtained by subtracting the maximum heating time from the heating time.

[0029] Each unit board to be heated is heated based on the waiting time and the heating sequence.

[0030] By adopting the above technical solution, the maximum heating time and the heating sequence of at least two heating unit boards are determined according to the sorting results. The difference between the maximum heating time and the total heating time is the waiting time corresponding to the heating unit. This allows the electronic device to heat each heating unit board according to the waiting time and the heating sequence, thereby achieving the effect of simultaneous display of all unit boards in the LED display screen.

[0031] In another possible implementation, the LED display screen comprises at least two unit boards; the method further includes:

[0032] If the LED display screen is detected to be in display mode and the heating device is in working mode, then the current temperature increase rate and the third temperature of any unit board are obtained.

[0033] If the third temperature reaches the second preset temperature, heating of any of the unit boards is stopped;

[0034] The second temperature increase rate of any unit board is obtained, and the second temperature increase rate is the temperature increase rate of any unit board after heating is stopped.

[0035] If the second temperature increase rate is not less than the current temperature increase rate, then the position information of any unit board will be output.

[0036] By adopting the above technical solution, since the LED display screen itself also dissipates heat when in display mode, the temperature increase rate of the unit board will be faster when the LED display screen itself generates heat and the heating device is used for heating, which will reach the upper temperature limit of the unit board that cannot work normally much faster. The third temperature of any unit board is obtained so that subsequent determination of whether to stop heating the unit board can be made based on the third temperature and the second preset temperature. Simultaneously, the current temperature increase rate is obtained, and the temperature increase rate of the unit board after heating is stopped is obtained, i.e., the second temperature increase rate of the unit board, so as to determine whether the heating device corresponding to the unit board has stopped heating the unit board. When the second temperature increase rate is not less than the current temperature increase rate, it indicates that the heating device of the unit board is still working, that is, the heating device corresponding to the unit board is abnormal. If the heating device is used continuously, the unit board will not be able to display normally. Therefore, the location information of the unit board needs to be output. Since each unit board corresponds to a heating device, this allows users to know the location information of the abnormal heating device in a timely manner, thus facilitating users to handle the abnormal heating device and reducing the possibility of unit board damage.

[0037] In another possible implementation, the method further includes:

[0038] Obtain the duration for which the LED display screen is in the off state;

[0039] If the shutdown duration reaches the preset shutdown duration, the heating device corresponding to the unit board is controlled to heat the unit board.

[0040] By adopting the above technical solution, the off-time of the LED display screen in the off state is obtained. The longer the off-time, the longer the LED display screen has not worked, that is, the longer each heating device in the LED display screen has not worked. When the off-time reaches the preset off-time, it means that the LED display screen has been in a low-temperature environment for too long. The longer the LED display screen is in a low-temperature environment, the greater the possibility of component damage. Therefore, it is necessary to control the heating device corresponding to the control board to heat the unit board to increase the service life of the LED display screen.

[0041] Secondly, this application provides a device for low-temperature display of an LED screen, which adopts the following technical solution:

[0042] A device for low-temperature LED display, comprising:

[0043] The first acquisition module is used to acquire the current temperature of the unit board inside the LED display screen when a temperature acquisition command triggered by the user is detected. Each unit board has a corresponding heating device.

[0044] The second acquisition module is used to determine the unit board as the unit board to be heated when the current temperature does not reach the first preset temperature, and to acquire the position information of the unit board to be heated.

[0045] The first control module is used to control the heating device corresponding to the unit board to heat the unit board based on the position information of the unit board to be heated;

[0046] The second control module is used to control the LED display screen to display when the temperature is heated to the first preset temperature.

[0047] By adopting the above technical solution, when a user-triggered temperature acquisition command is detected, it indicates that the user needs to turn on the LED display screen. However, since the LED display screen may not turn on when the temperature is too low, the first acquisition module needs to acquire the current temperature of the unit boards inside the LED display screen to determine whether the unit boards can be turned on normally. When the current temperature has not reached the first preset temperature, it indicates that the unit board needs to be heated. This unit board is identified as the unit board to be heated, and the second acquisition module acquires the position information of the unit board to be heated to determine the specific position of the unit board to be heated. This allows the first control module to control the heating device corresponding to the unit board to be heated to heat the unit board more accurately. When the temperature reaches the first preset temperature, it indicates that the LED display screen can display normally, and the second control module controls the LED display screen to display. This achieves the effect of normal operation of the LED display screen under low temperature conditions.

[0048] In another possible implementation, when the first control module controls the heating device corresponding to the unit board to be heated to heat the unit board, it is specifically used for:

[0049] Obtain the heating rate of the heating device;

[0050] Based on the first preset temperature, the heating rate, and the current temperature, the heating time of the unit board to be heated is determined;

[0051] The heating unit board is heated based on the heating time.

[0052] In another possible implementation, when the first control module determines the heating time of the unit board to be heated based on the first preset temperature, the heating rate, and the current temperature, it is specifically used for:

[0053] The temperature difference value is obtained by subtracting the first preset temperature from the current temperature;

[0054] Based on the temperature difference and the heating rate, the heating time of the unit board to be heated is calculated.

[0055] In another possible implementation, when the first control module heats the unit board to be heated based on the heating time, it is specifically used for:

[0056] Obtain the number of the unit plates to be heated;

[0057] If the number of the unit boards to be heated is one, then the unit board to be heated is heated based on the heating time.

[0058] If the number of the heating unit boards is at least two, the heating time corresponding to each heating unit board is sorted to obtain a sorting result, and each heating unit board is heated based on the sorting result.

[0059] In another possible implementation, when the first control module heats each of the heating unit plates based on the sorting result, it is specifically used for:

[0060] Based on the sorting results, the maximum heating time and the heating sequence of the at least two heating unit plates are determined;

[0061] The waiting time of the unit board to be heated is obtained by subtracting the maximum heating time from the heating time.

[0062] Each unit board to be heated is heated based on the waiting time and the heating sequence.

[0063] In another possible implementation, the LED display screen consists of at least two unit boards; the device further includes:

[0064] The third acquisition module is used to acquire the current temperature increase rate and the third temperature of any unit board when it is detected that the LED display screen is in display state and the heating device is in working state.

[0065] The heating stop module is used to stop heating any of the unit boards when the third temperature reaches the second preset temperature.

[0066] The fourth acquisition module is used to acquire the second temperature growth rate of any unit board, wherein the second temperature growth rate is the temperature growth rate of any unit board after heating is stopped;

[0067] The output module is used to output the position information of any unit board when the second temperature growth rate is not less than the current temperature growth rate.

[0068] In another possible implementation, the device further includes:

[0069] The fifth acquisition module is used to acquire the off duration of the LED display screen in the off state;

[0070] The third control module is used to control the heating device corresponding to the unit board to heat the unit board when the shutdown duration reaches the preset shutdown duration.

[0071] Thirdly, this application provides an electronic device that adopts the following technical solution:

[0072] An electronic device comprising:

[0073] One or more processors;

[0074] Memory;

[0075] One or more applications, wherein the applications are stored in memory and configured to be executed by one or more processors, the applications being configured to: perform a method for low-temperature display of an LED display screen according to any possible implementation of the first aspect.

[0076] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution:

[0077] A computer-readable storage medium, when the computer program is executed in a computer, causes the computer to perform the method of low-temperature display of an LED display screen as described in any one of the first aspects.

[0078] In summary, this application includes at least one of the following beneficial technical effects:

[0079] 1. When a user-triggered temperature acquisition command is detected, it indicates that the LED display needs to be turned on. However, since the LED display may not turn on when the temperature is too low, it is necessary to acquire the current temperature of the unit boards within the LED display to determine whether the unit boards can be turned on normally. If the current temperature has not reached the first preset temperature, it indicates that the unit board needs to be heated. This unit board is identified as the unit board to be heated, and its position information is acquired to determine the specific location of the unit board to be heated. This allows for more accurate heating of the unit board by controlling the corresponding heating device. When the temperature reaches the first preset temperature, it indicates that the LED display can display normally, and the LED display is controlled to display. This achieves the effect of normal operation of the LED display under low temperature conditions.

[0080] 2. Since the LED display screen itself generates heat when in display mode, continuing to use a heating device while the LED display screen itself is generating heat will cause the unit board's temperature to rise faster than using the heating device alone. This will quickly reach the upper temperature limit where the unit board cannot function properly. Therefore, it's necessary to obtain the third temperature of any unit board to determine whether heating should be stopped based on the third temperature and the second preset temperature. Simultaneously, the current temperature rise rate and the second temperature rise rate after heating is stopped are also obtained to determine if the corresponding heating device has stopped heating the unit board. If the second temperature rise rate is not less than the current temperature rise rate, it indicates that the heating device is still operating, meaning there is an abnormality in the heating device. Continuing to use the heating device will cause the unit board to malfunction. Therefore, the location information of the unit board needs to be output. Since each unit board has a corresponding heating device, this allows users to promptly identify the location of any abnormal heating devices, facilitating troubleshooting and reducing the risk of unit board damage.

[0084] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0085] After reading this specification, those skilled in the art may make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0086] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0087] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0088] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0089] This application provides a method for low-temperature display on an LED screen, executed by an electronic device. This electronic device can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication. This application does not impose any limitations on this. Figure 1 As shown, the method includes steps S101, S102, S103, S104, and S105, wherein,

[0090] Step S101: If a user-triggered temperature acquisition command is detected, the current temperature of each unit board in the LED display screen is acquired.

[0091] Each unit panel has a corresponding heating device.

[0092] In this embodiment of the application, when a user-triggered temperature acquisition command is detected, it indicates that the LED display screen needs to be turned on. However, due to the inherent characteristics of the components that make up the LED display screen, such as the power supply temperature being below -20°C, they will not function properly. Furthermore, the LED display screen is composed of interconnected unit boards. Therefore, before turning on the LED display screen, the current temperature of each unit board within the LED display screen is acquired. This facilitates subsequent determination of whether each unit board within the current LED display screen needs heating based on the current temperature. Assume the LED display screen includes unit board A, unit board B, unit board C, and unit board D, where the current temperature of unit board A is -40°C, the current temperature of unit board B is -42°C, the current temperature of unit board C is -39°C, and the current temperature of unit board D is -45°C.

[0093] Users can trigger temperature acquisition commands via display devices such as mice and touchscreens.

[0094] Step S102: If the current temperature of at least one unit board has not reached the first preset temperature, then at least one unit board is identified as a unit board to be heated, and the position information of the unit board to be heated is obtained.

[0095] In this embodiment, the first preset temperature is a pre-set temperature, representing the minimum temperature at which the unit board can operate normally. Assuming the first preset temperature is -20℃, taking step S101 as an example, if the current temperature of none of the unit boards within the LED display screen reaches -20℃, it indicates that the unit boards within the LED display screen need to be heated. The unit boards that have not reached -20℃ are identified as the unit boards to be heated, i.e., unit boards A, B, C, and D are all unit boards to be heated. The corresponding position information of the unit boards to be heated is obtained as position information A, position information B, position information C, and position information D, respectively, so that the unit boards to be heated can be accurately heated subsequently.

[0096] Step S103: Based on the position information of the unit board to be heated, control the heating device corresponding to the unit board to heat the unit board.

[0097] In this embodiment of the application, the heating device corresponding to the unit board to be heated is controlled to heat the unit board according to the position information of the unit board to be heated, thereby achieving a more accurate heating effect on the unit board to be heated. Taking step S102 as an example, the electronic device controls the heating device A corresponding to unit board A to heat unit board A according to the position information A of unit board A. This enables the electronic device to heat unit board A more accurately.

[0098] Step S104: When the temperature reaches the first preset temperature, control the LED display screen to display the information.

[0099] In this embodiment, the first preset temperature is a pre-set temperature, representing the minimum temperature at which the unit boards can operate normally. Assuming the first preset temperature is -20℃, when unit boards A, B, C, and D all reach this temperature, it indicates that they can operate normally and control the LED display screen to display correctly. This achieves the effect of enabling the LED display screen to function normally at low temperatures.

[0100] One possible implementation of this application embodiment is that step S103, when controlling the heating device corresponding to the unit board to be heated to heat the unit board, specifically includes steps S1031 (not shown in the figure), S1032 (not shown in the figure), and S1033 (not shown in the figure), wherein...

[0101] Step S1031: Obtain the heating rate of the heating device.

[0102] In this embodiment of the application, the heating rate of the heating device is obtained so that the heating time for each unit plate to be heated can be determined based on the heating rate, combined with the first preset temperature and the current temperature. It is assumed that the heating rate of the heating device corresponding to each unit plate to be heated is the same, which is 1℃ / S (heating 1 degree Celsius per second).

[0103] One approach is to measure and calculate the heating device before it is put into use to determine the heating rate, or to obtain heating records of the heating device being used multiple times on the LED display screen and calculate the heating rate based on these records.

[0104] Step S1032: Based on the first preset temperature, heating rate and current temperature, determine the heating time of the unit board to be heated.

[0105] For the embodiments of this application, taking steps S101, S102, and S1031 as examples, the heating time for unit board A is determined to be 20 seconds, the heating time for unit board B is 22 seconds, the heating time for unit board C is 19 seconds, and the heating time for unit board D is 25 seconds. Determining the heating time for each unit board allows for accurate heating of each unit board in subsequent processes.

[0106] Step S1033: Heat the heating unit board based on the heating time.

[0107] In this embodiment of the application, taking step S1032 as an example, the heating device corresponding to the electronic device control unit board A can reach a normal operating temperature in 20 seconds. Therefore, by heating the unit board to be heated according to the heating time, the heating device can heat the unit board to be heated more accurately.

[0108] In one possible implementation of this application embodiment, step S1032, when determining the heating time of the unit board to be heated based on the first preset temperature, heating rate, and current temperature, specifically includes steps S10321 (not shown in the figure) and S10322 (not shown in the figure), wherein...

[0109] Step S10321: Divide the first preset temperature by the current temperature to obtain the temperature difference value.

[0110] For an embodiment of this application, taking step S1032 as an example, the difference between -20℃ and -40℃, -42℃, -39℃, and -45℃ is calculated to obtain the temperature difference values ​​of unit board A (20℃), unit board B (22℃), unit board C (19℃), and unit board D (25℃).

[0111] Step S10322: Calculate the heating time of the unit board to be heated based on the temperature difference and the heating rate.

[0112] In this embodiment of the application, taking step S10322 as an example, 20℃, 22℃, 19℃, and 25℃ are divided by 1℃ / S respectively to obtain the heating time for unit board A as 20S, unit board B as 22S, unit board C as 19S, and unit board D as 25S. This facilitates subsequent heating of each unit board according to its heating time.

[0113] One possible implementation of this application embodiment, when heating the heating unit plate based on the heating time, specifically includes steps S10331 (not shown in the figure), S10332 (not shown in the figure), and S10333 (not shown in the figure), wherein...

[0114] Step S10331: Obtain the number of unit plates to be heated.

[0115] In this embodiment of the application, the number of unit boards to be heated is obtained in order to determine the specific heating measures to be performed on the unit boards to be heated.

[0116] Step S10332: If the number of unit boards to be heated is one, then the unit board to be heated is heated based on the heating time.

[0117] In this embodiment of the application, taking step S102 as an example, assuming that only unit board A is the unit board to be heated, it means that only heating unit board A is needed for the LED display screen to display normally. Therefore, the heating device corresponding to the electronic device control unit board A can work for 20 seconds to enable unit board A to work normally, thereby enabling the LED display screen to display normally.

[0118] Step S10333: If the number of heating unit plates is at least two, sort the heating time corresponding to each heating unit plate to obtain the sorting result, and heat each heating unit plate based on the sorting result.

[0119] In this embodiment of the application, taking step S102 as an example, unit board A, unit board B, unit board C, and unit board D are all unit boards to be heated, meaning there are at least two unit boards to be heated. If heating is performed according to the heating time of each unit board, the time it takes for each unit board to work normally will differ. If the unit boards to be heated are controlled to work simultaneously, the screen display will be incomplete. Therefore, the heating times are sorted, resulting in a sorting result of 25S, 22S, 20S, and 19S. The heating device is controlled sequentially according to the sorting result so that the unit boards to be heated can simultaneously reach the first preset temperature, reducing the occurrence of situations where the LED display screen cannot display images simultaneously.

[0120] In this embodiment of the application, step S10332 or step S10333 is executed according to the number of unit plates to be heated obtained in step S10331.

[0121] One possible implementation of this application embodiment, when heating each unit plate to be heated based on the sorting result in step S10333, specifically includes steps S103331 (not shown in the figure), S103332 (not shown in the figure), and S103333 (not shown in the figure), wherein,

[0122] Step S103331: Based on the sorting results, determine the maximum heating time and the heating sequence of at least two heating unit plates.

[0123] For the embodiments of this application, taking step S10333 as an example, the maximum heating time is determined to be 25 seconds, and the heating sequence of the heating device controlled by the electronic device is unit board D, unit board B, unit board A, and unit board C. That is, the electronic device first needs to control the heating device of unit board D to turn on, then control the heating device of unit board B to turn on, then control the heating device of unit board A to turn on, and finally control the heating device of unit board C to turn on.

[0124] In this embodiment, when the heating time of the unit boards to be heated is the same, the electronic device will control the heating devices corresponding to the same unit boards to be heated to turn on simultaneously. Assuming that the heating time of unit board A is 20 seconds, the heating time of unit board B is 20 seconds, and the heating time of unit board C is 22 seconds, the heating sequence controlled by the electronic device is as follows: first, the heating device corresponding to unit board C is turned on, and then the heating devices corresponding to unit board A and unit board B are turned on simultaneously.

[0125] Step S103332: Subtract the maximum heating time from the heating time to obtain the waiting time for each heating unit plate.

[0126] For the embodiments of this application, taking step S10333 as an example, the difference between 25S and 21S, 22S, 20S and 19S is calculated respectively to obtain the waiting time of unit board D as 0S, the waiting time of unit board B as 3S, the waiting time of unit board A as 5S and the waiting time of unit board C as 6S.

[0127] Step S103333: Heat each unit board to be heated based on the waiting time and heating sequence.

[0128] For the embodiments of this application, taking steps S103331 and S103332 as examples, it is assumed that the heating device corresponding to control unit board D is turned on at 0 seconds, the heating device corresponding to control unit board B is turned on at 3 seconds, the heating device corresponding to control unit board A is turned on at 5 seconds, and finally the heating device corresponding to control unit board C is turned on at 6 seconds. Here, 0 seconds indicates that the heating device of unit board D is turned on immediately, and turning on indicates that the heating device begins to heat the unit board to be heated.

[0129] In this embodiment, the heating speed of the heating device corresponding to each unit board is the same. Furthermore, when the heating speed of the heating device corresponding to each unit board is variable, the heating speed of each heating device is adjusted according to the temperature difference corresponding to each unit board. This ensures that each unit board reaches the first preset temperature simultaneously when the heating devices are turned on at the same time.

[0130] One possible implementation of this application embodiment further includes steps S105 (not shown in the figure), S106 (not shown in the figure), S107 (not shown in the figure), and S108 (not shown in the figure), wherein step S105 can be executed after step S104, wherein,

[0131] Step S105: If the LED display screen is detected to be in display mode and the heating device is in working mode, then the current temperature increase rate and the third temperature of any unit board are obtained.

[0132] In this embodiment, since the LED display screen generates heat when it is in display mode, and the heating device continues to heat it while the LED display screen itself is generating heat, the temperature of the unit boards inside the LED display screen increases rapidly. Consequently, the time it takes for the corresponding unit board to reach its maximum temperature limit, which prevents it from working properly, is shorter. Therefore, the current temperature increase rate of any unit board and its temperature (the third temperature) are obtained to determine whether heating of any unit board needs to be stopped. Assume that the current temperature increase rate of unit board A is 4°C / s and the third temperature is 30°C.

[0133] Step S106: If the third temperature reaches the second preset temperature, then stop heating any unit board.

[0134] In the embodiments of this application, the second preset temperature is a temperature set in advance. Assuming the second preset temperature is 20°C, taking step S105 as an example, the third temperature of unit board A has reached the second preset temperature. This means that if unit board A continues to increase its heat at the current rate, it will cause unit board A to reach the upper limit of temperature that cannot work normally in a relatively short time. That is, it is necessary to control the heating device corresponding to unit board A to stop heating unit board A, thereby slowing down the temperature increase rate of unit board A.

[0135] Step S107: Obtain the second temperature increase rate of any unit plate.

[0136] The second temperature growth rate is the temperature growth rate after any unit plate stops heating.

[0137] In this embodiment of the application, taking step S106 as an example, the second temperature increase rate of unit plate A is obtained to determine whether the heating device corresponding to unit plate A is turned off. Assume the second temperature increase rate of unit plate A is 4°C / s.

[0138] Specifically, the second temperature growth rate of unit board A can be obtained by taking the temperature after the heating device corresponding to electronic control unit board A is turned off, taking the temperature again after a specified time, taking the difference between the two temperatures, and removing the difference by the specified time to obtain the second temperature growth rate.

[0139] Step S108: If the second temperature growth rate is not less than the current temperature growth rate, then output the position information of any unit board.

[0140] For the embodiments of this application, taking steps S105 and S107 as examples, if the second temperature increase rate of unit board A is not less than the current temperature increase rate, it indicates that the electronic device has not successfully controlled the heating device of unit board A to stop heating, that is, there is an abnormality in the heating device corresponding to unit board A. If the heating device is used continuously, unit board A will not be able to display normally. Therefore, the position information of unit board A needs to be output. Since each unit board has a corresponding heating device, it is possible for the user to know the position information of the abnormal heating device in a timely manner, so that the user can handle the abnormal heating device and reduce the possibility of damage to the unit board.

[0141] The location information of unit board A can be output to the user's terminal device, or it can be played through a speaker, or other output methods are not limited here.

[0142] In this embodiment, when an anomaly is detected in any unit board, the location information of that unit board is output, and it can also be determined whether the unit board belongs to an edge unit board based on the location information. If it belongs to an edge unit board, the unit board can be controlled to stop working, thereby reducing its temperature. If it does not belong to an edge unit board, an emergency signal is sent so that the user is aware that the electronic device is currently unable to self-regulate.

[0143] Furthermore, after stopping the operation of the unit board, in order to ensure the user's viewing experience, the horizontal or vertical unit boards of the unit board can be stopped simultaneously according to the position information of the unit board, and the display screen of the working unit boards can be readjusted so that the LED display screen can display the image completely even in the event of an abnormality.

[0144] One possible implementation of this application embodiment further includes steps S109 (not shown in the figure) and S110 (not shown in the figure), wherein step S109 may be executed before step S101, wherein,

[0145] Step S109: Obtain the off duration of the LED display screen in the off state.

[0146] In this embodiment of the application, a longer shutdown time indicates a longer period of inactivity for the LED display screen, and further indicates a longer period of time the LED display screen is in a low-temperature environment. The shutdown time of the LED display screen in the off state is obtained to determine the duration of the LED display screen in a low-temperature environment, thereby determining whether the LED display screen needs to be heated. Assume the shutdown time of the LED display screen is 21 hours.

[0147] In step S110, if the shutdown duration reaches the preset shutdown duration, the heating device corresponding to the control unit board heats the unit board.

[0148] In this embodiment of the application, the preset shutdown time is the maximum duration for which the LED display screen is in the off state, set in advance. Assuming the preset shutdown time is 20 hours, taking step S109 as an example, the LED display screen has reached the preset shutdown time, indicating that the LED display screen has been in a low-temperature environment for too long. The longer the LED display screen is in a low-temperature environment, the greater the possibility of component damage. Therefore, it is necessary to control the heating device corresponding to the control board to heat the unit board to increase the service life of the LED display screen.

[0149] The above embodiments describe a method for low-temperature display of an LED display screen from the perspective of process flow. The following embodiments describe a device for low-temperature display of an LED display screen from the perspective of virtual modules or virtual units.

[0166] If there are at least two heating unit boards, the heating time corresponding to each heating unit board is sorted to obtain the sorting result, and each heating unit board is heated based on the sorting result.

[0167] In one possible implementation of this application embodiment, when the first control module 203 heats each unit plate to be heated based on the sorting result, it is specifically used for:

[0168] Based on the sorting results, determine the maximum heating time and the heating sequence of at least two heating unit plates;

[0169] The difference between the maximum heating time and the heating time is used to obtain the waiting time of the unit board to be heated;
