The LED display screen is a planar screen formed by using LED lattice modules or pixel units, and because the packaging material of the LED device in the prior art is usually epoxy resin, the gaps among molecules are larger, and gaseous water molecules can enter the inside of the shell through the gaps to cause the lamp beads to be wetted, therefore, if the LED display screen is not used for a long time, the LED display screen is very likely to be damaged due to the fact that the lamp beads are wetted when being electrified together with high current.

In this embodiment of the present application, it is considered that the current that the lamp beads can bear under different humidity is different, and the working current of the lamp beads is determined by the brightness of the played video, so, by pre-storing a plurality of video files in the display screen management device 11 in advance, the display screen can realize dehumidification under different humidity conditions by playing video files with different brightness, thereby achieving the purpose of protecting the lamp beads.
Specifically, in the embodiment of the present application, each video file includes a plurality of video segments with brightness levels, and the brightness levels and/or time intervals between two adjacent video segments in different video files are different. Wherein, the brightness level represents the difference value of the brightness levels corresponding to the two adjacent video clips, and the time interval represents the time interval between the starting points of the two adjacent video clips (i.e. the duration corresponding to the previous video clip in the two adjacent video clips).
For example, in one possible embodiment, the first video file stored in the display management device 11 includes three video clips with brightness levels of 0, 50, and 100%, where the video clip with brightness of 0 corresponds to 30 minutes, the video clip with brightness level of 50 corresponds to 30 minutes, and the video clip with brightness level of 100 corresponds to 15 minutes; the second video file stored in the display management apparatus 11 includes 5 video clips having luminance levels of 0, 20%, 40%, 70%, and 100%, respectively, wherein the video clip having luminance of 0 corresponds to a period of 1 hour, the video clip having luminance level of 20% corresponds to a period of 1 hour, the video clip having luminance level of 40% corresponds to a period of 1 hour, the video clip having luminance level of 70% corresponds to a period of 30 minutes, and the video clip having luminance level of 100% corresponds to a period of 10 minutes. And, the video clips in the first video file and the second video file are arranged in the order from low brightness level to high brightness level.
It should be noted that, in the embodiment of the present application, the brightness level and/or the time interval of the other video files stored in the display management device 11 may be similar, which is not exemplified here.
The following describes in detail a method for managing a display screen provided in an embodiment of the present application with reference to fig. 3, where the method includes:
step S10, acquiring environmental parameters of the environment where the display screen is located, wherein the environmental parameters comprise humidity parameters.
Specifically, in the embodiment of the present application, the environmental parameter may be acquired through a detection device such as a sensor that is communicatively connected to the display screen management apparatus 11. For example, in one possible implementation, the humidity parameter may be obtained by detecting an area where the display screen is located by using a humidity sensor, and then the collected humidity parameter is sent to the display screen management device 11 by using the humidity sensor, so that the display screen management device 11 performs subsequent processing on the collected environmental parameter.
Further, the method comprises:
step S20, determining whether the environmental parameter is within a preset parameter threshold range.
In this embodiment, the parameter threshold range may be set according to the management requirement, for example, in a possible implementation manner, the parameter threshold range may be set to 0-30% rh, which means that when the ambient humidity does not exceed 30% rh, the display screen dehumidification function is not required to be started or the influence of humidity on the display screen is not required to be considered, and when the ambient humidity is greater than 30% rh, the display screen is required to be dehumidified.
Further, with continued reference to fig. 3, after step S20 the method further comprises:
and step S30, if the video file is not in the parameter threshold range, searching a corresponding target video file from a plurality of pre-stored video files according to the environment parameters.
Specifically, in the embodiment of the present application, each pre-stored video file is configured with an environmental humidity corresponding thereto. Therefore, when it is detected in the step S20 that the humidity of the environment where the display screen is located exceeds the parameter threshold range, the target video file matched with the current humidity of the environment where the display screen is located can be found out through the corresponding relationship between the video file and the environment humidity.
For example, when the preset environmental humidity is 60% rh, the corresponding video file is the first video file, when the environmental humidity is 80% rh, the corresponding video file is the second video file, when the humidity of the environment where the display screen is located is detected to be 60% rh, the first video file is used as the target video file, and when the humidity of the environment where the display screen is detected to be 80% rh, the second video file is used as the target video file.
Further, with continued reference to fig. 3, after step S30 the method further comprises:
and step S40, the target video file is sent to the display screen, and the display screen is controlled to play the target video file.
After a target video file matched with the environment humidity of the environment where the display screen is located is found, the target video file is sent to a receiving card of the display screen, and then the display screen is driven by the receiving card to play the target video file, so that the lamp beads can work with proper working current, and the effect of dehumidifying the lamp beads is achieved on the premise that the lamp beads are not damaged.
Specifically, in this embodiment of the present application, the video clips in each video file are arranged in order from low to high in brightness level, and in the process of sending the target video file to the display screen, the display screen management device 11 may send each video clip in the target video file to the display screen in order from low to high in brightness level, and control the display screen to sequentially play each video clip in the same order, so that the lamp beads dry themselves with gradually increased power.
By the method, the lamp beads can be dehumidified by playing video files with different brightness according to different environmental humidity, the safety of the lamp beads is ensured to a great extent, and the lamp beads are prevented from being damaged due to the fact that the lamp beads cannot bear excessive current in the dehumidification process due to moisture.
Further, considering that the working current which can be borne by the lamp beads in the display screen is also related to the historical use condition (such as the use frequency, the last use time and the like) of the lamp beads, and the moisture resistance of different types of display screens is different, in another embodiment of the application, besides the humidity parameter, the type information of the display screen and/or the corresponding relation between the historical use information of the display screen and the video file are further increased, so that the accuracy of the video file matched with the display screen under different conditions is further improved.
For example, in one possible implementation, for a frequency of usage of humidity lower than 60% rh once a week (about 8 hours of usage), the beads used for the display screen are gold thread lamps, and the surface of the beads has a plating working condition, because the humidity is normal, the effect on the beads is small, and the display screen has better moisture-proof performance, so that a video file with a larger brightness level and a smaller time interval can be configured corresponding to the video file. For example: the video clips with three brightness levels are respectively 0, 50 and 100%, wherein the video clip with the brightness level of 0 corresponds to 5 minutes, the video clip with the brightness level of 50% corresponds to 10 minutes, and the video clip with the brightness level of 100% corresponds to 20 minutes.
For the use frequency of 3 days (4 hours for each day) of use of the display screen within the humidity range of 60-80% RH, the lamp beads used by the display screen are gold thread lamps, but the surface of the lamp beads has no plating film working condition, and the influence on the display screen is larger due to higher humidity, and the moistureproof performance of the lamp beads is relatively weaker, so that video files with smaller brightness level and larger time interval can be configured to correspond to the video files. For example: the video clips with five brightness levels are respectively 0, 20%, 40%, 70 and 100%, wherein the video clip with the brightness level of 0 corresponds to 2 hours, the video clip with the brightness level of 20% corresponds to 1 minute, the video clip with the brightness level of 40% corresponds to 40 minutes, the video clip with the brightness level of 70% corresponds to 20 minutes, and the video clip with the brightness level of 100% corresponds to 5 minutes.
It should be understood that, in the embodiment of the present application, the correspondence between each video file and the working condition of the display screen may be set according to actual requirements, and is not limited to the above-listed several corresponding cases.
It should also be appreciated that in embodiments of the present application, the environmental parameters may include, but are not limited to, the humidity parameters described above.
For example, in another possible implementation manner, considering that the dehumidification efficiency of the lamp beads is related to the ambient temperature, the humidity parameter of the environment where the display screen is located is collected, and meanwhile, the temperature parameter of the area where the display screen is located is also collected, and the corresponding relationship between the temperature parameter and the video file is configured.
The following describes a process of configuring the corresponding relation between each video file and the current working condition of the display screen in the embodiment of the present application with reference to fig. 4.
Referring to fig. 4, in the embodiment of the present application, a process of configuring a correspondence between each video file and a current working condition of a display screen includes:
and S01, determining the brightness level and time interval matched with the display screen under the current condition according to at least one of the environment parameters or the type information and the historical use information of the display screen and the environment parameters.
Step S02, searching a video file matched with the brightness level and the time interval from the stored video files, and configuring the corresponding relation between the video file and the environment parameters or the type information and the history use information of the video file and the display screen and the environment parameters.
In this embodiment, the operating current to which the display screen is adapted under various operating conditions may be preconfigured, and then the brightness level and the time interval to which the display screen is adapted under various operating conditions may be obtained according to the operating current. When the video files are stored, the corresponding relation between the video files and the working conditions of the display screen can be configured according to the corresponding relation and the brightness level and the time interval corresponding to each video file.
Specifically, when the working conditions of the display screen include humidity parameters of the environment in which the display screen is located, a corresponding relation between each humidity parameter (or parameter range) and the video file may be configured, and when the working conditions of the display screen include display screen type and/or display screen historical use information in addition to the humidity parameters, a corresponding relation between each video file and the humidity parameter (or parameter range), display screen type and/or display screen historical use information may be configured.
After the configuration is completed, the display management device 11 may search the target video file suitable for the current working condition of the display according to the pre-configured correspondence, so as to control the display to play the target video file to achieve reasonable dehumidification.
Referring to fig. 5, a block diagram of a display management apparatus 70 according to an embodiment of the present application is provided, which may be applied to a display management device 11 in the display management system 10 shown in fig. 1, to provide a display dehumidification management function for the display management device 11. Specifically, the device includes an acquisition module 701, a judgment module 702, a search module 703, a control module 704, and a configuration module 705.
