[0031] The embodiments of the present application are described in detail below.

[0032] The related technology uses the following two methods to solve the problem of red lamp bead attenuation during the display process of LED display screen, as follows:

[0033] 1. Through thermal correction and other methods, pulse width modulation (PWM) is adjusted to control the working current of the LED display.

[0034] 2. By adjusting the pulse signal, the working timing of the control circuit of the LED display screen can make the display effect of the lamp beads on the display screen consistent.

[0035] The adjustment of these two methods is relatively mechanical, resulting in unclear optimization of the screen display effect.

[0036] In order to solve the defects in the related art, the embodiment of the present application provides a display control method, which is applied to an electronic device, wherein the electronic device includes an LED display screen, and the LED display screen includes k display modules, where k is an integer greater than 1; the method may include the following steps:

According to the k second working parameters, the k display modules are controlled to display the content to be displayed. First, since the red lamp beads are prone to attenuation, the display brightness of the red lamp beads can be mainly considered to perform targeted compensation. Second, dynamic compensation is achieved based on the characteristics of the display module and the actual situation of the displayed content, which helps to improve the display effect and enhance the user experience.

The content to be displayed may include at least one of the following: video, image, icon, etc., which are not limited here. Then, the display brightness of the red lamp beads corresponding to the content to be displayed can be determined to obtain m first display brightnesses, where m is an integer greater than 1. Since red lamp beads are prone to attenuation, the display brightness of the red lamp beads can be mainly considered, and targeted compensation can be performed to improve the display effect.

[0047] Each display module may also correspond to a display area.

[0048] 102. Determine a compensation parameter of each display module in the k display modules according to the m first display brightnesses to obtain k compensation parameters.

[0049] In a specific implementation, the m first display brightnesses reflect the characteristics of the content (image) to be displayed. The compensation parameters of each of the k display modules are determined according to the m first display brightnesses to obtain k compensation parameters. That is, dynamic compensation can be achieved based on the actual situation of the display content, which helps to improve the display effect and enhance the user experience.

[0050] 103. Obtain operating parameters of the k display modules to obtain k first operating parameters.

[0051] Among them, the working parameters of the display module may include at least one of the following: working current, working current, working power, working time, working frequency, working mode, etc., which are not limited here.

[0052] In a specific implementation, the operating parameters of k display modules may be acquired to obtain k first operating parameters, and each display module corresponds to one first operating parameter.

[0053] 104. Compensate corresponding first operating parameters among the k first operating parameters according to the k compensation parameters to obtain k second operating parameters.

[0054] In a specific implementation, corresponding first working parameters among k first working parameters can be compensated according to k compensation parameters to obtain k second working parameters. Since dynamic compensation is realized based on the characteristics of the display module and the actual situation of the display content, it helps to improve the display effect and enhance the user experience.

[0055] 105. Control the k display modules to display the content to be displayed according to the k second working parameters.

[0056] In a specific implementation, each of the k display modules can control a display area, thereby achieving division of labor and assistance, and targeted compensation, that is, controlling the k display modules to display the content to be displayed according to the k second working parameters. Since dynamic compensation is achieved based on the characteristics of the display modules and the actual situation of the display content, it helps to improve the display effect and enhance the user experience.

[0057] It can be seen that the display control method described in the embodiment of the present application is applied to an electronic device, the electronic device includes an LED display screen, the LED display screen includes k display modules, k is an integer greater than 1, the content to be displayed is obtained, and the display brightness of the red lamp beads corresponding to the content to be displayed is determined to obtain m first display brightnesses, m is an integer greater than 1, the compensation parameters of each display module in the k display modules are determined according to the m first display brightnesses, and k compensation parameters are obtained, the working parameters of the k display modules are obtained, and k first working parameters are obtained, and the corresponding first working parameters in the k first working parameters are compensated according to the k compensation parameters to obtain k second working parameters. According to the k second working parameters, the k display modules are controlled to display the content to be displayed. First, since the red lamp beads are prone to attenuation, the display brightness of the red lamp beads can be mainly considered to perform targeted compensation. Second, dynamic compensation is achieved based on the characteristics of the display module and the actual situation of the displayed content, which helps to improve the display effect and enhance the user experience.

[0058] See also Figure 3 , Figure 3 1 is a flow chart of a display control method provided by an embodiment of the present application. As shown in the figure, it is applied to an electronic device, wherein the electronic device includes an LED display screen, and the LED display screen includes k display modules, where k is an integer greater than 1. The display control method includes:

[0059] 301. Obtain content to be displayed, and determine the display brightness of the red lamp beads corresponding to the content to be displayed, to obtain m first display brightnesses, where m is an integer greater than 1.

[0060] In a specific implementation, the electronic device may include an LED display screen, and the LED display screen includes k display modules, where k is an integer greater than 1, such as Figure 2 As shown, k display modules can constitute the entire LED display screen. The k display modules can be connected through a bus, and the k display modules can work synchronously. The synchronous work can be implemented by using k threads or k processes, and each display module corresponds to one thread or one process.

[0061] In an embodiment of the present application, the content to be displayed can be obtained from the cache. The content to be displayed may include at least one of the following: video, image, icon, etc., which are not limited here. Then, the display brightness of the red lamp beads corresponding to the content to be displayed can be determined to obtain m first display brightnesses, where m is an integer greater than 1. Since red lamp beads are prone to attenuation, the display brightness of the red lamp beads can be mainly considered, and targeted compensation can be performed to improve the display effect.

[0062] Each display module may also correspond to a display area.

[0063] 302. Determine a display brightness greater than a preset threshold among the m first display brightnesses, and obtain n second display brightnesses, where n is a positive integer less than or equal to m.

[0064] The preset threshold value may be preset or set by system default.

[0065] In a specific implementation, when the first display brightness is less than or equal to a preset threshold, it means that the red lamp bead at that position is weakly displayed, and its effect on the display effect is very weak and can be ignored. Furthermore, when the first display brightness is greater than the preset threshold, it means that the red lamp bead at that position is stronger, which will have a certain impact on the display effect. Therefore, the display brightness greater than the preset threshold among the m first display brightnesses can be determined to obtain n second display brightnesses, where n is a positive integer less than or equal to m. Furthermore, compensation is only performed for the position where the red lamp bead displays stronger, thereby improving the display effect.

[0066] 303 . Determine a second display brightness set in each of the k display modules according to the n second display brightnesses to obtain k second display brightness sets.

[0067] In a specific implementation, the second display brightness set in each of the k display modules can be determined according to the n second display brightnesses to obtain k second display brightness sets, that is, the second display brightness of each of the k display modules is determined to obtain k second display brightness sets, and the number of second display brightnesses that can be included in each of the k second display brightness sets is a natural number.

[0068] Among them, all the second display brightnesses in the k second display brightness set are n second display brightnesses.

[0069] 304. Determine the attenuation parameter of the red lamp bead corresponding to each second display brightness set in the k second display brightness sets to obtain k attenuation parameter sets; each attenuation parameter in each attenuation parameter set is used to characterize the attenuation degree of the corresponding red lamp bead.

[0070] In a specific implementation, the attenuation parameter of the red lamp bead corresponding to each second display brightness set in the k second display brightness sets can be determined to obtain k attenuation parameter sets, that is, each display module can correspond to an attenuation parameter set, each attenuation parameter set includes a natural number of attenuation parameters, and each attenuation parameter is used to characterize the attenuation degree of the corresponding red lamp bead. The attenuation parameter can also correspond to the position of a red lamp bead.

[0071] 305 . Determine a compensation parameter of each of the k display modules according to the k attenuation parameter sets and the k second display brightness sets to obtain k compensation parameters.

[0072] In a specific implementation, k attenuation parameter sets reflect the characteristics of each display module, and k second display brightness sets reflect the display conditions of each display area. Furthermore, the compensation parameters of each of the k display modules can be determined based on the k attenuation parameter sets and the k second display brightness sets to obtain k compensation parameters. Thus, dynamic compensation can be achieved based on the characteristics of the display modules and the actual conditions of the displayed content, which helps to improve the display effect and user experience.

[0073] The value range of the compensation parameter may be preset or set by system default. For example, the value range of the compensation parameter may be between 0 and 0.2.

[0074] 306. Obtain operating parameters of the k display modules to obtain k first operating parameters.

[0075] Among them, the working parameters of the display module may include at least one of the following: working current, working current, working power, working time, working frequency, working mode, etc., which are not limited here.

[0076] In a specific implementation, the operating parameters of k display modules may be acquired to obtain k first operating parameters, and each display module corresponds to one first operating parameter.

[0077] 307. Compensate corresponding first operating parameters among the k first operating parameters according to the k compensation parameters to obtain k second operating parameters.

[0078] In a specific implementation, corresponding first working parameters among k first working parameters can be compensated according to k compensation parameters to obtain k second working parameters. Since dynamic compensation is realized based on the characteristics of the display module and the actual situation of the display content, it helps to improve the display effect and enhance the user experience.

[0079] 308. Control the k display modules to display the content to be displayed according to the k second working parameters.

[0080] In a specific implementation, each of the k display modules can control a display area, thereby achieving division of labor and assistance, and targeted compensation, that is, controlling the k display modules to display the content to be displayed according to the k second working parameters. Since dynamic compensation is achieved based on the characteristics of the display modules and the actual situation of the display content, it helps to improve the display effect and enhance the user experience.

[0081] Optionally, the above step 305, determining the compensation parameter of each of the k display modules according to the k attenuation parameter sets and the k second display brightness sets to obtain k compensation parameters, may include the following steps:

[0082] Determine a first mean and a first standard deviation of a first attenuation parameter set, where the first attenuation parameter set is any attenuation parameter set among the k attenuation parameter sets;

[0083] determining a second mean and a second standard deviation of a target second display brightness set corresponding to the first attenuation parameter set;

[0084] determining a first compensation parameter corresponding to the first mean value;

[0085] Determining a first adjustment parameter corresponding to the second mean;

[0086] determining a first relative deviation between the first standard deviation and the second standard deviation;

[0087] determining a first fine-tuning parameter corresponding to the first relative deviation;

[0088] A compensation parameter corresponding to the first attenuation parameter set is determined according to the first compensation parameter, the first adjustment parameter and the first fine-tuning parameter.

[0089] In a specific implementation, taking the first attenuation parameter set as an example, the first attenuation parameter set is any attenuation parameter set among the k attenuation parameter sets, then the first attenuation parameter set can be subjected to a mean operation to obtain a first mean, and the first attenuation parameter set can be subjected to a standard deviation operation to obtain a first standard deviation. The first mean reflects the overall attenuation degree of the display module corresponding to the first attenuation parameter set when displaying the content to be displayed, and the first standard deviation reflects the overall attenuation stability of the display module corresponding to the first attenuation parameter set when displaying the content to be displayed.

[0090] Correspondingly, the target second display brightness set corresponding to the first attenuation parameter set can be operated on for a mean value to obtain a second mean value, and the target second display brightness set can be operated on for a standard deviation to obtain a second standard deviation. The second mean value reflects the display degree, and the second standard deviation reflects the stability of the display effect.

[0091] In a specific implementation, a mapping relationship between a preset mean and a compensation parameter can be pre-stored, and then, a first compensation parameter corresponding to the first mean can be determined based on the mapping relationship, that is, targeted compensation can be made for the overall attenuation degree of the display module when displaying the content to be displayed, thereby preliminarily ensuring that the display effect is deeply adapted to the characteristics of the display module and the characteristics of the image itself.

[0092] Next, the mapping relationship between the preset mean and the adjustment parameter can be pre-stored, and then the first adjustment parameter corresponding to the second mean can be determined based on the mapping relationship. To a certain extent, different display effects will also have a certain impact on the display under the attenuation state. The second mean reflects the display degree. In this way, the display effect can be further optimized based on the display effect.

[0093] Next, the first relative deviation between the first standard deviation and the second standard deviation can also be determined, the first relative deviation = (first standard deviation - second standard deviation) / (first standard deviation + second standard deviation). Since the first standard deviation reflects the overall attenuation stability of the display module corresponding to the first attenuation parameter set when displaying the content to be displayed, and the second standard deviation reflects the stability of the display effect, the display effect can be deeply optimized by deeply combining the characteristics of the display module and the characteristics of the image itself.

[0094] In a specific implementation, a mapping relationship between a preset relative deviation and a fine-tuning parameter can be pre-stored, and then, a first fine-tuning parameter corresponding to the first relative deviation can be determined based on the mapping relationship, and then the compensation parameter corresponding to the first attenuation parameter set is determined according to the first compensation parameter, the first adjustment parameter and the first fine-tuning parameter. Specifically, the compensation parameter corresponding to the first attenuation parameter set = the first compensation parameter * (1 + the first adjustment parameter) * (1 + the first fine-tuning parameter), wherein the value range of the first adjustment parameter can be -0.12 to 0.12, and the value range of the first fine-tuning parameter can be -0.02 to 0.02. In this way, the compensation parameters can be deeply optimized so that the final compensation parameters are deeply adapted to the characteristics of the display module and the characteristics of the image itself.

[0095] Optionally, the above step 307, compensating corresponding first operating parameters among the k first operating parameters according to the k compensation parameters to obtain k second operating parameters, may include the following steps:

[0096] Compensating a target first operating parameter corresponding to the first compensation parameter according to a first compensation parameter to obtain a reference operating parameter, wherein the first compensation parameter is any compensation parameter among the k compensation parameters;

[0097] Determining a first environmental parameter of the display module corresponding to the first compensation parameter;

[0098] Determining a first feedback adjustment parameter corresponding to the first environmental parameter;

[0099] Feedback adjustment is performed on the reference operating parameter according to the first feedback adjustment parameter to obtain a second operating parameter corresponding to the first compensation parameter.

[0100] In a specific implementation, the first compensation parameter can be taken as an example. The first compensation parameter is any compensation parameter among k compensation parameters. The target first working parameter corresponding to the first compensation parameter can be compensated according to the first compensation parameter to obtain a reference working parameter, that is, the reference working parameter = (1 + first compensation parameter) * target first working parameter.

[0101] Among them, the first environmental parameter may include at least one of the following: hardware environment parameters, software environment parameters, physical environment parameters, etc., which are not limited here. Hardware environment parameters may include at least one of the following: hardware type, hardware configuration parameters, etc., which are not limited here. Software environment parameters may include at least one of the following: operating system parameters, network environment parameters, etc., which are not limited here. Physical environment parameters may include at least one of the following: ambient temperature, ambient brightness, ambient humidity, magnetic field interference intensity, etc., which are not limited here.

[0102] In a specific implementation, the first environmental parameter of the display module corresponding to the first compensation parameter can be determined, and the mapping relationship between the preset environmental parameters and the feedback adjustment parameters can be pre-stored. Then, the first feedback adjustment parameter corresponding to the first environmental parameter can be determined based on the mapping relationship, and then the reference working parameter can be feedback-adjusted according to the first feedback adjustment parameter to obtain the second working parameter corresponding to the first compensation parameter, that is, the second working parameter = (1 + first feedback adjustment parameter) * reference working parameter. On the one hand, the compensated working parameters can be initially made to deeply adapt to the characteristics of the display module and the characteristics of the image itself. On the other hand, the compensated working parameters can be adjusted based on the real-time environmental parameter feedback, so that the final working parameters are deeply consistent with the actual environment, further ensuring the display effect and improving the user experience.

[0103] Optionally, the following steps may also be included:

[0104] Performing target extraction on the content to be displayed to obtain a target area and a background area;

[0105] Determining a first average display brightness and a first area of ​​the target area;

[0106] Determine a second average display brightness and a second area of ​​the background area;

[0107] determining a first ratio of the first area to the second area;

[0108] determining a reference threshold value corresponding to the first ratio;

[0109] determining a second relative deviation between the first average display brightness and the second average display brightness;

[0110] determining a second feedback adjustment parameter corresponding to the second relative deviation;

[0111] Feedback adjustment is performed on the reference threshold according to the second feedback adjustment parameter to obtain the preset threshold.

[0112] In a specific implementation, a target may be extracted for the content to be displayed to obtain a target area and a background area, and then a first average display brightness and a first area of ​​the target area may be determined, as well as a second average display brightness and a second area of ​​the background area may be determined, and then a first ratio of the first area to the second area may be determined, that is, the first ratio = the first area / the second area. A mapping relationship between a preset ratio and a threshold may also be pre-stored, and then a reference threshold corresponding to the first ratio may be determined based on the mapping relationship. In this way, the first ratio reflects the screen share corresponding to the target to a certain extent, and the screen share reflects the user's attention to a certain extent. The corresponding threshold is dynamically determined based on the user's attention. For example, for content that the user does not pay attention to, the compensation may be appropriately reduced, and for content that the user pays attention to, the compensation may be appropriately increased.

[0113] Next, the second relative deviation between the first average display brightness and the second average display brightness can also be determined, the second relative deviation = (first average display brightness - second average display brightness) / (first average display brightness + second average display brightness), the second relative deviation reflects to a certain extent the degree of contrast difference between the target area and the background area, and the degree of contrast difference is deeply related to human visual characteristics, and then, the mapping relationship between the preset relative deviation and the feedback adjustment parameter can be pre-stored, and then, the second feedback adjustment parameter corresponding to the second relative deviation can be determined based on the mapping relationship, that is, the reference threshold can be feedback-adjusted according to the second feedback adjustment parameter to obtain the preset threshold, then the preset threshold = (1 + second feedback adjustment parameter) * reference threshold, the threshold is further dynamically adjusted based on the contrast difference, so that the final threshold selection depth is deeply related to the user's attention and the image itself, which can not only ensure the compensation efficiency but also the display effect.

[0114] Optionally, the above step 304, determining the attenuation parameter of the red lamp bead corresponding to each second display brightness set in the k second display brightness sets to obtain k attenuation parameter sets, may include the following steps:

[0115] Determining a first usage time of the LED display screen;

[0116] Determine a reference attenuation parameter of the red lamp bead corresponding to the first usage time;

[0117] Acquire a first ambient temperature corresponding to a red lamp bead corresponding to a target second display brightness, wherein the target second display brightness is a second display brightness in any second display brightness set among the k second display brightness sets;

[0118] determining a target error parameter corresponding to the first ambient temperature;

[0119] The attenuation parameter of the red lamp bead corresponding to the target second display brightness is determined according to the target error parameter and the reference attenuation parameter.

[0120] In a specific implementation, the first usage time of the LED display screen can be determined. The longer the usage time, the more severe the attenuation. Therefore, the mapping relationship between the preset usage time and the attenuation parameter can be pre-stored. Then, the reference attenuation parameter of the red lamp bead corresponding to the first usage time can be determined based on the mapping relationship.

[0121] Next, taking the target second display brightness as an example, the target second display brightness is the second display brightness of any second display brightness set among k second display brightness sets, then the first ambient temperature corresponding to the red lamp bead corresponding to the target second display brightness can be obtained. Due to the influence of temperature, there will be a certain error in the determination of the attenuation parameter. The mapping relationship between the preset ambient temperature and the error parameter can be pre-stored, and then the target error parameter corresponding to the first ambient temperature can be determined based on the mapping relationship, that is, the attenuation parameter of the red lamp bead corresponding to the target second display brightness can be determined according to the target error parameter and the reference attenuation parameter, that is, the attenuation parameter of the red lamp bead corresponding to the target second display brightness = (1 + target error parameter) * reference attenuation parameter, that is, the attenuation parameter of each red lamp bead can be preliminarily determined based on the usage time, and the attenuation parameter can be calibrated based on the actual ambient temperature, so that the final attenuation parameter depth conforms to the actual environment, thereby helping to ensure compensation accuracy, improve display effects, and improve user experience.

[0122] It can be seen that the display control method described in the embodiment of the present application is applied to an electronic device, wherein the electronic device includes an LED display screen, and the LED display screen includes k display modules, where k is an integer greater than 1; obtain the content to be displayed, and determine the display brightness of the red lamp beads corresponding to the content to be displayed, to obtain m first display brightnesses, where m is an integer greater than 1; determine the display brightness greater than a preset threshold among the m first display brightnesses, to obtain n second display brightnesses, where n is a positive integer less than or equal to m; determine the second display brightness set in each display module of the k display modules according to the n second display brightnesses, to obtain k second display brightness sets; determine the attenuation parameter of the red lamp beads corresponding to each second display brightness set in the k second display brightness sets, to obtain k attenuation parameter sets; each attenuation parameter in each attenuation parameter set is used to characterize the attenuation degree of the corresponding red lamp beads; according to the k attenuation The parameter set and k second display brightness sets determine the compensation parameters of each display module in the k display modules to obtain k compensation parameters; obtain the working parameters of the k display modules to obtain k first working parameters; compensate the corresponding first working parameters in the k first working parameters according to the k compensation parameters to obtain k second working parameters; control the k display modules to display the content to be displayed according to the k second working parameters. Firstly, since the red lamp beads are prone to attenuation, the display brightness of the red lamp beads can be mainly considered to perform targeted compensation. Secondly, when the first display brightness is greater than the preset threshold, it means that the red lamp beads at this position are displayed strongly, which will have a certain impact on the display effect. Only the position where the red lamp beads display strongly is compensated. Thirdly, dynamic compensation is achieved based on the characteristics of the display module and the actual situation of the displayed content, which helps to improve the display effect and enhance the user experience.
