[0035] Step S101: The electronic device acquires several historical field information displayed on the screen.

[0036] In step S102, the electronic device predicts the field to be displayed based on the historical field information, and the first time to display the field to be displayed.

[0037] In step S103, the electronic device determines whether there is a risk of light decay in the target LED light source corresponding to the field to be displayed.

[0038] Step S104: If the target LED light source corresponding to the field to be displayed is at risk of light decay, the electronic device determines the alternative LED light source corresponding to the field to be displayed.

[0039] In step S105, the electronic device triggers the operation of the alternative LED light source corresponding to the field to be displayed at the first moment.

[0040] The method for controlling LED light sources provided in this disclosure predicts the field to be displayed and the first time to display the field based on historical field information already displayed on the screen. If the target LED light source corresponding to the field to be displayed is at risk of light decay, the method triggers the operation of a backup LED light source corresponding to the field to be displayed immediately. This allows the backup LED light source to replace the target LED light source when it is at risk of light decay, thus ensuring the display brightness and improving the user experience.

[0041] Optionally, the field to be displayed corresponds to one target LED light source and multiple backup LED light sources. Determining the backup LED light source corresponding to the field to be displayed includes: arbitrarily selecting one backup LED light source as the backup LED light source corresponding to the field to be displayed.

[0042] Optionally, the historical field information includes historical fields and a second time when the display shows the historical fields; predicting the field to be displayed based on the historical field information, and the first time to display the field to be displayed, includes: obtaining the currently displayed field on the display at the current moment, predicting the field to be displayed based on the currently displayed field, each historical field, and each second time, and the first time to display the field to be displayed. In this way, the field to be displayed can be predicted based on the currently displayed field on the display at the current moment.

[0043] Combination Figure 2 As shown, this disclosure provides a method for controlling an LED light source, including:

[0044] Step S201: The electronic device acquires several historical field information displayed on the screen.

[0045] Step S202: The electronic device obtains the currently displayed field shown on the display screen at the current moment.

[0046] In step S203, the electronic device predicts the field to be displayed based on the currently displayed field, each historical field, and each second time, as well as the first time to display the field to be displayed.

[0047] In step S204, the electronic device determines whether there is a risk of light decay in the target LED light source corresponding to the field to be displayed.

[0048] Step S205: If the target LED light source corresponding to the field to be displayed is at risk of light decay, the electronic device determines the alternative LED light source corresponding to the field to be displayed.

[0049] In step S205, the electronic device triggers the operation of the alternative LED light source corresponding to the field to be displayed at the first moment.

[0050] The method for controlling LED light sources provided in this disclosure predicts the field to be displayed based on historical field information already displayed on the screen, determines the first time to display the field, and triggers the operation of a backup LED light source corresponding to the field in the first instance if there is a risk of light decay in the target LED light source corresponding to the field. This allows the backup LED light source to replace the target LED light source when there is a risk of light decay, thus ensuring the display brightness and improving the user experience of the electronic device.

[0051] Optionally, based on the currently displayed field, each historical field, and each second time point, predict the field to be displayed, and the first time point for displaying the field to be displayed, the process includes: sorting each historical field in descending order according to the second time point to obtain a historical field information sorting list; identifying historical fields identical to the currently displayed field as first candidate fields; obtaining second candidate fields corresponding to each first candidate field from the historical field information sorting list; in the historical field information sorting list, first candidate fields are adjacent to their corresponding second candidate fields, and the second time point for displaying the second candidate field is greater than the second time point for displaying the corresponding first candidate field; sorting each second candidate field in descending order according to its frequency of occurrence; and identifying the second candidate field ranked first as the field to be displayed; obtaining the time difference between the second candidate field closest to the current time point and its corresponding first candidate field; and determining the first time point as the sum of the current time point and the time difference.

[0052] Optionally, determining whether the target LED light source corresponding to the field to be displayed is at risk of light decay includes: obtaining the cumulative usage time of the target LED light source, and determining whether the target LED light source is at risk of light decay based on the cumulative usage time. Since the lifespan of an LED light source is basically fixed, obtaining the cumulative usage time of the target LED light source can determine whether the target LED light source is at risk of light decay.

[0053] Further, determining whether the target LED light source has a risk of light decay based on the cumulative usage time includes: obtaining the average temperature of the display screen during use and determining whether the average temperature is less than a first preset threshold. If the average temperature is greater than or equal to the first preset threshold, determining whether the cumulative usage time is less than a second preset threshold. If the cumulative usage time is greater than or equal to the second preset threshold, determining that the target LED light source has a risk of light decay. And / or; if the cumulative usage time is less than the second preset threshold, determining that the target LED light source does not have a risk of light decay. Since the lifespan of an LED light source decreases with increasing temperature, obtaining the average temperature of the area where the target LED light source is located can be obtained by acquiring the average temperature of the display screen during use. By determining whether the average temperature is greater than or equal to the first preset threshold, it can be determined whether the average temperature of the area where the target LED light source is located is greater than or equal to the first preset threshold. And if the average temperature is greater than or equal to the first preset threshold, determining whether the cumulative usage time of the target LED light source is greater than or equal to the second preset threshold can determine whether the target LED light source has a risk of light decay.

[0054] Optionally, after determining whether there is a risk of light decay in the target LED light source corresponding to the field to be displayed, the method further includes: if there is no risk of light decay in the target LED light source corresponding to the field to be displayed, triggering the target LED light source to run at the first moment.

[0055] Combination Figure 3 As shown, this disclosure provides a method for controlling an LED light source, including:

[0056] Step S301: The electronic device acquires several historical field information displayed on the screen.

[0057] In step S302, the electronic device predicts the field to be displayed based on the historical field information, and determines the first time to display the field to be displayed.

[0058] Step S303: The electronic device acquires the cumulative usage time of the target LED light source.

[0059] Step S304: The electronic device acquires the average temperature of the display screen during use.

[0060] Step S305: If the average temperature of the electronic device is greater than or equal to a first preset threshold, determine whether the cumulative usage time is greater than or equal to a second preset threshold. If yes, proceed to step S306. Otherwise, proceed to step S307.

[0061] In step S306, the electronic device determines that the target LED light source has a risk of light decay and determines the alternative LED light source corresponding to the field to be displayed. Then, step S308 is executed.

[0062] In step S307, the electronic device determines that the target LED light source does not pose a risk of light decay. Then, step S309 is executed.

[0063] In step S308, the electronic device triggers the operation of the alternative LED light source corresponding to the field to be displayed at the first moment.

[0064] In step S309, the electronic device triggers the target LED light source corresponding to the field to be displayed to run at the first moment.

[0065] The method for controlling LED light sources provided in this disclosure predicts the field to be displayed based on historical field information already displayed on the screen, and determines whether the target LED light source has a risk of light decay based on the cumulative usage time of the target LED light source corresponding to the field to be displayed and the average temperature of the area. This allows for a more accurate determination of whether the target LED light source has a risk of light decay. Then, if the target LED light source has a risk of light decay, the alternative LED light source corresponding to the field to be displayed is triggered to operate immediately. In this way, when the target LED light source corresponding to the field to be displayed has a risk of light decay, the alternative LED light source corresponding to the field to be displayed can be used to replace the target LED light source, thereby ensuring the display brightness and guaranteeing the user's experience when using the electronic device.

[0066] Optionally, after determining whether the average temperature is less than a first preset threshold, the method further includes: if the average temperature is less than the first preset threshold, determining whether the cumulative usage time is less than a third preset threshold. If the cumulative usage time is greater than or equal to the third preset threshold, it is determined that the target LED light source has a risk of light decay. And / or, if the cumulative usage time is less than the third preset threshold, it is determined that the target LED light source does not have a risk of light decay; the third preset threshold is greater than the second preset threshold. Since the lifespan of an LED light source decreases with increasing temperature, and if the average temperature is less than the first preset threshold, it can be determined that the lifespan of the target LED light source is relatively long. Therefore, using the third preset threshold as a benchmark allows for a more accurate determination of whether the target LED light source has a risk of light decay.

[0073] In step S406, the electronic device determines that the target LED light source has a risk of light decay and determines the alternative LED light source corresponding to the field to be displayed. Then, step S408 is executed.

[0074] In step S407, the electronic device determines that there is no risk of light decay in the target LED light source. Then, step S409 is executed.

[0075] In step S408, the electronic device triggers the operation of the alternative LED light source corresponding to the field to be displayed at the first moment.

[0076] In step S409, the electronic device triggers the target LED light source corresponding to the field to be displayed to run at the first moment.

[0077] The method for controlling LED light sources provided in this disclosure predicts the field to be displayed based on historical field information already displayed on the screen, and determines whether the target LED light source has a risk of light decay based on the cumulative usage time of the target LED light source corresponding to the field to be displayed and the average temperature of the area. This allows for a more accurate determination of whether the target LED light source has a risk of light decay. Then, if the target LED light source has a risk of light decay, the alternative LED light source corresponding to the field to be displayed is triggered to operate immediately. In this way, when the target LED light source corresponding to the field to be displayed has a risk of light decay, the alternative LED light source corresponding to the field to be displayed can be used to replace the target LED light source, thereby ensuring the display brightness and guaranteeing the user's experience when using the electronic device.

[0079] The device for controlling LED light sources provided in this disclosure predicts the field to be displayed based on historical field information already displayed on the screen. When the target LED light source corresponding to the field to be displayed is at risk of light decay, and the first time interval corresponding to the field is reached, the device triggers the operation of a backup LED light source corresponding to the field to be displayed. This allows the backup LED light source to replace the target LED light source when it is at risk of light decay, thereby ensuring the display brightness and improving the user experience of the electronic device.
