How to ensure the stability of transparent LED screen
Transparent LED displays are widely used in various fields to play commercial advertisements and rental activities. In order to ensure the smooth operation of advertisements and the smooth development of performances and other activities, we need transparent LED screens to maintain a stable working operation, so how should we do it?
Below we will introduce the solution to the stability of the transparent LED screen from three aspects, let’s take a look together:
1. Material selection
The key materials that determine the stability of the transparent LED display include LED lights, driver ICs, power supplies, power signal connectors and excellent structural design. Our requirements for material selection are: well-known international brands, relevant tests higher than industry standards, and requirements for various protection functions. For example, switching power supply selection requirements: overheat protection, AC input must support wide voltage, anti-surge. The DC output must have overvoltage and overcurrent protection. The structural design not only ensures the beautiful and fashionable cabinet, but also ensures good heat dissipation and fast splicing.
2. System control scheme
Every link of the system control has a hot backup function, including video sending and receiving equipment, signal transmission cables, etc., which can ensure that when an unexpected situation occurs in a certain link of the system, the system can automatically diagnose and switch to the The standby equipment works, and the whole switching process will not affect the display effect on site. For example: in order to meet the needs of the stage scene, the display screen needs to be mobile spliced and shaped at the live broadcast site. If due to the negligence of the staff or other reasons, a certain display screen signal input line in the middle of the large screen is loose, in the conventional control scheme, from the box where the loosening occurs to the end of the signal cascade, all display screens There will be no signal. If a hot backup solution is added to the control system, the hot backup function will be activated at the moment the signal line is loose, and the display will still work normally without any impact on the live broadcast.
3. LED transparent screen working status monitoring
Computer real-time monitoring, including temperature, humidity, voltage, smoke, working status of cooling fans, etc. It can automatically adjust and process various situations that occur, and provide location and alarm for abnormalities. For example: when the internal temperature of a certain cabinet is relatively high due to the environment or other factors, the power supply inside the cabinet will be over-temperature protected at any time if it is not dealt with in time. If the working status of the display screen is monitored in this case, the system will intelligently adjust the working status of the transparent LED glass screen to reduce its internal temperature. When the intelligent adjustment cannot reduce the temperature to the set target, the system will alarm through the setting method of the staff, and provide the location of the abnormal box, and notify the staff to deal with it in time. Ensure the normal working condition of the display screen.
