First, referring to fig. 1, a method for controlling an LED display screen according to an embodiment of the present invention is specifically described.
Fig. 1 is a schematic flow chart of a method for controlling an LED display screen according to the present invention, where this embodiment is applicable to monitoring conditions of an LED display screen, and the method may be executed by a control device of the LED display screen to control a monitoring process of the LED display screen, where the control device of the LED display screen may be composed of hardware and/or software, and may be generally integrated in a device, and the device may be any device having a data processing function. The test method of the recognition algorithm specifically comprises the following steps:
s101, detecting the working time and/or the dead pixel rate of the LED display screen at regular time.
In the embodiment, the timing refers to a preset time period, so as to detect the working time and/or the dead pixel rate of the LED display screen according to the set time period. The time period for detecting the working time of the LED display screen can be different from the time period for detecting the dead pixel rate of the LED display screen.
Optionally, the working time of the LED display screen may be detected by detecting the energization time of the receiving card in the LED display screen at regular time; and/or detecting the dead pixel rate of the LED display screen by detecting the number of dead pixels acquired by the receiving card in the LED display screen at regular time.
It can be understood that, in the present embodiment, detecting the operating time and/or the dead pixel rate of the LED display screen may be detecting the operating time of the LED display screen; or detecting the defective pixel rate of the LED display screen; or, the operating time and the defective pixel rate of the LED display screen are detected at the same time, which is not limited herein.
S102, if the working time of the LED display screen is smaller than the working time threshold value in the control period, controlling the distribution box to electrify the LED display screen.
In this embodiment, the control period may be preset when the LED display screen leaves the factory; or, the setting may be customized according to the usage scenario of the LED display screen by the user, and the like, and is not limited in this respect.
The working duration threshold may be a standard working duration threshold preset when the LED display screen leaves a factory; or, the working time threshold set by the user according to the usage scenario of the LED display screen may also be customized, which is not specifically limited herein.
In the embodiment of the invention, whether the working time of the LED display screen is less than the working time threshold value in the control period or not is determined by comparing the working time of the LED display screen with the working time threshold value in the control period. If the working time of the LED display screen is greater than or equal to the working time threshold value in the control period, controlling the LED display screen to normally operate without any treatment; if the working time of the LED display screen is less than the working time threshold value in the control period, it indicates that the lamp beads in the LED display screen are exposed in the external environment, and the condition of dead spots of the LED display screen can be caused due to overhigh temperature or overhigh humidity of the external environment.
Therefore, when the working time of the LED display screen is smaller than the working time threshold value in the control period, the LED display screen is electrified through the control distribution box, and the LED display screen is copied, so that dead spots of the LED display screen caused by the fact that the working time of the LED display screen is smaller than the working time threshold value in the control period are reduced or even avoided.
S103, if the dead pixel rate of the LED display screen is larger than the dead pixel rate threshold value, controlling and adjusting the environmental parameters of the LED display screen.
It should be noted that, corresponding to the detection of the operation duration and/or the dead pixel rate in S101, S102 and S103 are also in and/or relationship. Specifically, the working time of the LED display screen can be adjusted; or adjusting the dead pixel rate of the LED display screen; or simultaneously adjusting the working time and the dead pixel rate of the LED display screen.
The dead pixel rate threshold value can be adaptively set according to the condition that the dead pixel rate of the LED display screen causes visual influence on human eyes; or, the standard bad pixel rate threshold may also be preset when the LED display screen leaves the factory, and is not specifically limited here. E.g., 50ppm, 55ppm, etc. Among them, ppm (parts per million, Chinese name: parts per million).
Assuming that the threshold of the defective pixel rate is set according to the condition that the defective pixel rate of the LED display panel has a visual effect on human eyes, and when the defective pixel rate is 50ppm, the LED display panel has a visual effect on human eyes, the threshold of the defective pixel rate can be set to 45 ppm.
Optionally, the dead pixel rate of the LED display screen is compared with a dead pixel rate threshold, so as to determine whether the dead pixel rate of the LED display screen is greater than the dead pixel rate threshold. If the dead pixel rate of the LED display screen is smaller than or equal to the dead pixel rate threshold value, controlling the LED display screen to normally operate without any treatment; if the dead pixel rate of the LED display screen is greater than the dead pixel rate threshold value, it indicates that the dead pixel rate of the LED display screen is abnormal, and the normal watching effect of the user may be affected.
Therefore, when the dead pixel rate of the LED display screen is greater than the threshold value of the dead pixel rate, the environmental parameters of the LED display screen are controlled and adjusted to reduce the probability of dead pixels appearing on lamp beads of the LED display screen, improve the display effect of the LED display screen and prolong the service life of the LED display screen.

It can be understood that, in the present embodiment, adjusting the ambient temperature and/or the ambient humidity of the LED display screen may be adjusting the ambient temperature of the LED display screen; or adjusting the environment humidity of the LED display screen; or, the ambient temperature and the ambient humidity of the LED display screen are adjusted, which is not limited herein.
Further, before the environmental parameters of the LED display screen are controlled and adjusted, the environmental temperature and/or the environmental humidity of the LED display screen may be detected, and then the environmental parameters of the LED display screen are adjusted according to the detected environmental temperature and/or environmental humidity.

According to the control method of the LED display screen provided by the embodiment of the invention, the working duration and/or the dead pixel rate of the LED display screen are/is detected at regular time, and when the working duration of the LED display screen is less than the working duration threshold value in the control period, the distribution box is controlled to electrify the LED display screen; and/or when the dead pixel rate of the LED display screen is greater than the dead pixel rate threshold value, controlling and adjusting the environmental parameters of the LED display screen. Therefore, the LED display screen is controlled according to the detected working time and/or the detected dead pixel rate of the LED display screen, so that the service life of the LED display screen is prolonged, and the cost is saved.
On the basis of the above embodiment, S101 further includes: and if the working time of the LED display screen is less than the working time threshold in the control period, and/or the dead pixel rate of the LED display screen is greater than the dead pixel rate threshold, sending abnormal reminding information to a user.

the first method is as follows: and sending an abnormal reminding message to the user in a short message mode.
The second method comprises the following steps: and sending an abnormal reminding message to the user in a mail mode.
The above two modes are only exemplary illustrations of the embodiments of the present invention, and do not specifically limit the present invention.
In this embodiment, when it is determined that the operating time of the LED display screen is less than the operating time threshold in the control period and/or the dead pixel rate of the LED display screen is greater than the dead pixel rate threshold, the user can prevent the LED display screen in time by sending an abnormal reminding message to the user, so as to improve the viewing effect of the LED display screen.
On the basis of the embodiment, the ambient temperature and/or the ambient humidity of the LED display screen can be detected; if the ambient temperature of the LED display screen exceeds the temperature threshold, controlling and adjusting the ambient temperature of the LED display screen; and/or controlling and adjusting the ambient humidity of the LED display screen if the ambient humidity of the LED display screen exceeds a humidity threshold value.
The temperature threshold may be set by a user in a self-defined manner, or may be preset when the LED display screen leaves a factory, where the temperature threshold is not specifically limited. In this embodiment, the temperature threshold may be a range of values, such as: -10 ℃ to +40 ℃ and may be a specific value.

It can be understood that, in this embodiment, adjusting the ambient temperature and/or the ambient humidity of the LED display screen may refer to adjusting the ambient temperature of the LED display screen; or adjusting the environment humidity of the LED display screen; or, the ambient temperature and the ambient humidity of the LED display screen are adjusted, which is not limited herein.
Through the analysis, the working time and/or the dead pixel rate of the LED display screen are detected in a timing mode, so that the LED display screen is adjusted and controlled according to the working time and/or the dead pixel rate.
With reference to fig. 2, the following describes adjustment and control of the LED display screen according to the working time of the LED display screen in the embodiment of the present invention.
Fig. 2 is a flow chart of another control method of the LED display screen according to the present invention. As shown in fig. 2, the method for controlling an LED display screen according to the embodiment of the present invention specifically includes the following steps:
s201, detecting the working time of the LED display screen at regular time.
S202, if the working time of the LED display screen in the monitoring sub-period in the current control period is smaller than the first working time threshold, the distribution box is controlled to electrify the LED display screen in the adjustment sub-period in the current control period until the total working time of the LED display screen in the current control period reaches the second working time threshold.
Wherein the current control period consists of the monitoring sub-period and the adjusting sub-period.
In the embodiment of the invention, the monitoring sub-period and the adjusting sub-period can be set according to days; or by week, etc. For example, set by days, the monitoring sub-period may be set to 5 days, and the adjustment sub-period may be set to 2 days; alternatively, the monitoring sub-period is set to 6 days, the adjustment sub-period is set to 1 day, and so on.
For example, assuming that the current control period is 7 days, wherein the monitoring sub-period is the first 5 days, the adjusting sub-period is the second 2 days, the first working duration threshold is 10 hours (h), and the second working duration threshold is 14h, when the control device of the LED display determines that the working duration of the LED display screen in the first 5 days is 9h and is less than 10h, the distribution box is controlled to power on the LED display screen in the second 2 days to execute the copy operation, the working duration of the LED display in the first 5 days and the total working duration of the power-on duration of the LED display in the second 2 days are determined in the power-on process, the total working duration is compared with 14h, and if the total working duration is less than 14h, the LED display is continuously powered on until the total working duration is greater than or equal to 14 h.
According to the control method of the LED display screen provided by the embodiment of the invention, when the detected working time of the LED display screen in the monitoring sub-period in the current control period is determined to be less than the first working time threshold, the distribution box is controlled to electrify the LED display screen in the adjustment sub-period in the current control period until the total working time of the LED display screen in the current control period reaches the second working time threshold. Therefore, the problem that the copying operation cannot be executed due to the fact that the LED display screen does not work for a long time can be effectively avoided, the LED display screen is enabled to have dead spots due to wetting, and the service life of the LED display screen is prolonged.
Through the analysis, the LED display screen is adjusted and controlled according to the working time of the LED display screen.
In another implementation scenario, the embodiment of the invention can also adjust and control the LED display screen according to the defective pixel rate of the LED display screen. The LED display screen has the defect rate which comprises the defect rate in the current period and the total defect rate of the existing period. Therefore, the embodiment can adjust and control the LED display screen according to the defective pixel rate of the LED display screen in the current period; and/or adjusting the LED display screen according to the total failure point of the LED display screen in the existing period, which can be specifically described with reference to fig. 3 and 4.
First, referring to fig. 3, the adjustment control of the LED display screen is described according to the defective pixel rate of the LED display screen in the current period. As shown in fig. 3, the control method of the LED display screen specifically includes the following steps:
s301, determining the dead pixel rate of the LED display screen in the current period according to the number of the dead pixels acquired by the receiving card in the LED display screen in the current period.
Generally, a receiving card in the LED display screen has a function of detecting the number of dead pixels, so that the embodiment can detect the number of dead pixels of the LED display screen in the current period through the receiving card in the LED display screen. And then, calculating the defective pixel rate of the LED display screen in the current period according to the number of the defective pixels detected by the receiving card in the LED display screen.
In this embodiment, the dead pixel rate of the LED display screen in the current period can be calculated by formula (1):
a
S302, if the dead pixel rate of the LED display screen in the current period is larger than the single-period dead pixel rate threshold value, controlling and adjusting the environmental parameters of the LED display screen.
The single-cycle defective pixel rate threshold may be preset when the LED display screen leaves a factory, or may be set in other manners, and the threshold is not specifically limited herein. For example, 1ppm, 1.2 ppm.
For example, if the single-cycle defective pixel rate threshold is 1ppm, when the defective pixel rate of the LED display screen in the current cycle is 1.1ppm, it indicates that the defective pixel rate of the LED display screen in the current cycle is abnormal. At this moment, the control device of the LED display screen can adjust the environmental parameters of the LED display screen by starting the air conditioner and/or the fan, so that the LED display screen is prevented from continuously generating dead spots, the watching effect of the LED display screen is poor, and the normal watching of a user is influenced.
Referring to fig. 4, the adjustment control of the LED display screen is described according to the total number of bad points acquired by the LED display screen in the existing period. As shown in fig. 4, the control method of the LED display screen specifically includes the following steps:
s401, determining the total dead pixel rate of the LED display screen according to the total dead pixel number obtained by the receiving card in the LED display screen in the existing period.
According to the embodiment of the invention, the total number of the bad spots in the existing period of the LED display screen is detected through the receiving card in the LED display screen. And calculating the total defective pixel rate of the LED display screen according to the total defective pixel number detected by the receiving card in the LED display screen.
In this embodiment, the total dead pixel rate of the LED display screen can be calculated by formula (2):
a
S402, if the total dead pixel rate of the LED display screen is larger than the threshold value of the total dead pixel rate, controlling and adjusting the environmental parameters of the LED display screen.
The total dead pixel rate threshold may be preset when the LED display screen leaves a factory, or may be adaptively set according to an actual application scenario, and the like, which is not specifically limited herein. For example, 50ppm, 55ppm, 60ppm, etc.
For example, if the total defective pixel rate threshold is 50ppm, when the total defective pixel rate of the LED display screen is 51ppm, it indicates that the total defective pixel rate of the LED display screen is abnormal, so that the LED display screen is reduced or even prevented from continuously generating defective pixels by adjusting the environmental parameters of the LED display screen.
That is to say, in this embodiment, the total dead pixel rate of the LED display screen is determined, and the total dead pixel rate is compared with the total dead pixel rate threshold. And when the total dead pixel rate of the LED display screen is determined to be greater than the total dead pixel rate, controlling and adjusting the environmental parameters of the LED display screen to reduce or even avoid continuous dead pixels of the LED display screen, thereby improving the watching effect of the LED display screen.
